Why Gas Prices Are Rising Essay -- essays research papers

Gas prices risingOR EVEN ABOUT SQUEEZING a few much miles out of each precious tankful. But among the special-edition Ferraris, bizarre Cadillac studies and a whole tender crop of gas-guzzling SUVs, not all that many people were talking most cheaper and cleaner ways of getting around. The section of the show dedicated to New Energies was a little corner on the second floor of Hall 2, basis the stands of the insurance companies. in that respect were exactly two exhibits.The lull is deceiving. Never have so many automakers put as much money and effort into structure a fountainer car. Not entirely without some prodding, mind you. Facing clean-fleet laws in the U.S. and voluntary restrictions in Europe, the industry is committing to cut emissions of its gasoline and diesel-powered cars. Gridlocked Italian cities like capital of Italy and Milan may ban conventional cars altogether from their historic centers. In Tokyo, putting 30,000 natural-gas-powered taxis in the streets has al put in helped clean up the air. But most of all, carmakers have been whipped into pull through by Californias Zero Emissions Mandate that requires ten percent of all cars sold in the state to be pollution-free by 2003.Mention green cars, and most people think of some battery-powered buggy that the average driver wouldnt be caught dead in. Electric cars have been around for decades and neer caught on. Their problem batteries arent very powerful, so the cars speed, range and weight remain strictly limited. The typical result is Fords new THNK, already on the market in Scandinavia and about to hit a few dozen American dealers as well. The THNK is a tiny two-seater with a grubby-looking plastic shell that can go about 50 miles between recharges, at a top speed of 50 mph. A full charge takes eight hours, exclusively costs only 50 cents. With a sticker price of $15,000, the car provide win a bantam market niche at best. If youre not entrusting to put up with the performance of a glorified golf cart, there are invariably standard cars powered by alternative fuels like propane, ethanol or liquified natural gas. Also around for decades, these cars have actually begun to catch on. There are 4 million cars in the world today running on a propane/butane mix, including 1.2 million in Italy alone. Many gas stations aver this cleaner fuel as well, so chances are you dont have to drive very far for a fillup. GMs U.K.-based Vauxh... ...drogen in favor of methanol, which is simpler to transport and releases hydrogen fairly easily. Trouble is, methanol leaves toxic byproducts that need to be disposed. BMW uses a different technology, burning hydrogen in a conventional combustion engine. Clean steam comes out of the exhaust pipe. As with any other technology, theres a fierce battle for the standards that will define our hydrogen fuel-cell future. So while hydrogen may be what DaimlerChrysler CEO Juergen Schrempp calls the great big alternative, itll be a while yet in front this technology is mature enough to replace gasoline-powered cars on a grand scale. The first models will roll out in a few years, but theyll be expensive and hard to find a filling station for. But industry analysts predict that by 2010, the market will be ready another ten years, and half the cars sold in the world could run on hydrogen. Everyone is buying a ticket to the lottery because we all know that whoever wins will win big time, says Paul Everitt, chief economist at the Society of Motor Manufacturers and Traders. If hes right, greener cars will start to be a much hotter category at the auto show.

DISINVESTMENT OF PUBLIC SECTOR UNDERTAKINGS IN INDIATODAY THE RUSSIAN sparing MODEL OF DEVELOPMENT CON nonED THROUGH THE RUSSIAN FUR DOES NOT EXIST.TODAY THE CHINESE ECONOMIC MODEL OF DEVELOPMENT CONNOTED THROUGH THE MAO SUIT DOES NOT EXIST.Margaret Thatcher disrobed them. The concept of the GOLDEN STRAIGHT JACKET is avowed, to whether it were the Democrats or the Re earthly concernans, the Conservatives or the Laborites, the BJP or the Congress.The concept of the golden straight jacket has been embraced by all countries including India. It endeavors to shift the economical decision making from the government to the markets. The concept of Disinvestment being its major tenet.The Nehruvian temples of economic growth, better known as the Public Sector Undertakings were born as the outcome of the conscious policy of the government to speed up industrialization of the country with a view to giving added impetus to economic growth as well as achieve certain socio-economic goals.These u ndertakings account for of our GDP. They also account for 1/3 of our exports and have made contributions to import substitution. Also government undertakings rent more than 70% of the workers employed in the organized sector.These undertakings have helped reduce imbalances in regional development and a few of them have earned character for excellence at international level.But the picture is not as rosy as it seems, rather the scene in most of the PSUs is rattling chilling. According to figures upto March 99 losses incurred by 29 PSUs trebled within one year from approx. Rs.1050 crores to Rs. 3600 crores.The major reasons for the non performance of the PSUs can be summarized asPolitical Interference, High Cost of Delay, Fear of Scams, Headless Plants, Ineffective Management, Huge Inventories, Trade Unionism and Unutilized Capacities.A comprehensive policy on public sector was set out in the Industrial Policy Statement of July 24, 1991 - the year when the country had to tide over an unprecedented economic crisis reflected in its interior and external finances. The steps adumbrated included a review of public sector investments to focus on strategic and essential infrastructure enterprises and new procedures to tackle chronically sick and loss-making units.Rationality is least expected from an economist who is best defined as a man who tells you tomorrow why the things he predicted yesterday did not happen today.The DEPARTMENT OF DISINVESTMENT has the following rationale Because of the current revenue expenditure on items such as interest payments, wages and salaries of Government employee and subsidiaries, the Government is go away with hardly any surplus for capital expenditure on social and physical infrastructure.

Insurance Fraud :: essays research papers fc

Insurance FraudInsurance Fraud is becoming wholeness of the top forms of fraud in America. Martin Frankel owned several mansions, luxury cars, and diamonds. He lived a life of complete luxury. A life of luxury that was paid for with money stolen through insurance fraud. Martin Frankel is one of the major contributors to insurance fraud. He constructed a scheme to malversate over 200 million dollars from insurance companies in several states across the U.S. He began his send-off minor case of insurance fraud in 1986 and was not convicted until 2002 for insurance fraud, racketeering, and money laundering. Throughout his career he learned new ways to embezzle money and began to master the art of insurance fraud.Insurance fraud cost Americans billions of dollars every year as higher premium. It is viewed as mostly as a white-collar crime but it can come in many different forms. People who usually commit these kinds of frauds are motivated by voraciousness for necessity or seeking wea lth and luxury. This may have been the case with Martin Frankel as stated by the prosecutors he was motivated by greed, sexual proneness and a lust for the high life a mansion in Greenwich, fancy cars, diamonds the size of nickels, and several girlfriends.In 1986 convince a businessman named Douglas maxwell to join him in etablishing the Frankel Fund. The Frankel Fund was an investment partnership in which the limited partners had to invest at least $50,000 each. In 1991 the Frankel Fund failed and the Securities and Exchange Commission taboo him from dealing with securities business for life. After that he using false names he set up the Creative Partners Fund LP. This fund was another rook like the Frankel Fund but the minimum investment was only $10,000 and it spread through a much broader base of investors. He and his partner Sonia Schulte formed a thunor trust to purchase insurance companies that where in financial trouble.Martin Frankel made his millions from keeping the ve ry large reserves from the purchased insurance companies and spending it for luxuries instead of investing it and corrupt securities. He built a large false insurance empire through using the reserves to buy more and more insurance companies and thence transferring the money from company to company to look as if the money remained untouched. He called his scheme the Ponzi scheme after Charles Ponzi who became rich from a pyramid scheme.

Dietary Supplements Essay -- Work Out Supplements

There ar many different work push through supplements. Some of those work out supplements atomic number 18 Proteins/Amino Acids, Performance Supplements, Energy Boosting Products, and Vitamins. The first work out supplement we are going to tell you rough is Proteins/Amino Acids. One supplement that is made of Protein is called, The Ultimate Whey Designer Protein. This designer protein is 68% better than egg white and or regular whey. It mixes simplified and gives you up to 18 grams of protein per scoop. This supplement pull up stakes run you the consumer about $26.99 each 2 lbs bottle. This should last you a good 4 weeks. Another protein supplement is Promax Protein. This contains 50 grams of predigested, bioactive protein per serving it also contains less than 1 gram of fat and is sugar free.

Evolution of Ideas and Practices From Ancient Times :: essays research papers

Evolution of Ideas and Practices From Ancient TimesPlatos symposium is a array of speeches on what relish meant in the society. Although the term homosexuality was not present in ancient times, it was something that was well practiced. Men and wowork force still shared intercourse, but it was not cerebration of as wrong, or out of the norm, for there to be staminate and male interaction, and sometimes female and female interaction. Love, the kind shared between two males, came from personal attraction, emotional attraction and mental attraction. Love, the kind shared between a man and a woman came from emotional and mental attraction, and a need to procreate. subsequent the times of Plato female homosexuality was completely forbidden, although male homosexuality was deemed acceptable. Marriage was often just for procreation, but there was also love involved. Homosexuality in modern times is often thought of as wrong. It is thought of as completely inappropriate for two men or for two women to be unitedly in a sexual way. It is interesting to see how the idea and practice of homosexuality and the practice of love and marriage has evolved through the times.There was much male and male interaction in the times of Plato. Older men often took younger men under their wings. An older man would teach younger men about the world of love, politics, business etc. in return for sexual favors. In the beginning of Symposium Agathon requests that Socrates be seated next to him so that I may touch you, he said and have the benefit of that wise thought which came into your mind in the portico... Agathon believed that he were to touch Socrates and be with Socrates he could learn Socrates more wisdoms. It would not have been uncommon for the other men in the room to witness a sexual interaction between males, for they themselves surely participated in it. Although it is later learned that Socrates is not a enthusiast of sexual pleasures, he looks better upon stimulation of the brain.Who is really to say which kind of love is the true kind of love? Aristophenes tells a story of a different people, and Androgynous people. In the beginning a human was one being with quaternity arms, four hands, four legs, and four feet.

Effects of Peer Pressure on the Graduating of Angelicum College Essay

We learners have always been exposed to consort invite, but the kinds of peer puzzle out that they encounter have changed tremendously in the past classs. Peers can influence everything from whether or not a student engages in academics or new(prenominal) things. This is an in-chief(postnominal) topic because if society and education related professionals understand the issues surrounding negative peer influence, they atomic number 18 more likely to prevent it and be more adequately prepared to help a teenager facing positive and negative aspects of peer pressure sensation.The researchers dealt with the Effects of Peer Pressure on the Graduating Batch of Angelicum College, school year 2013-2013. The researchers examined the positive and negative deeds of peer pressure to the graduating learners. The researchers further attempted to find out whether the students are influenced by their friends in doing their modular activities or are they more motivated to work with their fri ends. The researchers conducted a survey to the randomly selected learners from the seven moderatorship classes from the graduating batch of Angelicum College school year 2012-2013. The survey was used to elicit the subjects perceptions of peer pressure on educational issues. In conducting the survey forms, the researchers used the term friends instead of peers and influence instead of pressure, so that the subject would not be pressured when answering the survey.The results showed how peer pressure affects the subjects academics and school life. The subjects answers on their interest in attending to the same college as their peers seem to be in a 50/50 percentage. The summary further revealed that peer pressure is a major factor to the academic achievement of the learners. The general conclusion emanating from this study was that first peers exert some influence on the students decisions concerning academic activities and aspirational decisions.Secondly, peers are somehow a huge f actor for the learners to work on the given modular activities. In general therefore, the researcher concludes that the effect of peer pressure largely affects the learners in their academic pacing. More research needs to be undertaken to compare the data taken from the learners in Angelicum College to the graduating learners in other schools. Also, to know other factors of peer pressure to the graduating learners should be studied to determine the effects on learner susceptibility to peer pressure.

Joplin Scott’s The Entertainer

Joplin Scotts The Entertainer is undoubtedly one of the most easily recognizable melodies in music. Its popularity can be considered part of popular culture that has lasted a century thanks to modern adaptations of the music. The piece created in the height of American rattle on time music, has a great history and is considered as an important cultural piece in African American art genre (French, 2007). Joplin himself is an icon of American music and proved himself devoted to his craft to develop ragtime music to a classical status.The SettingThe turn to the 20th century is among the most unfavourable times in history. Globally, the United States is becoming a leader, spearheading the industrial movement of internationalization of commerce. Within the United States itself, there was significant economic growth and kind development in terms of rights and suffrage movements. Though African Americans were still subject to a significant amount of legal and social discrimination, they were beginning to take aim interest and lobby movements and cultivate their identity in American society (Schafer et al, 1977, pp. 47-52).One of the fields that they gained recognition was in music. Strongly based in church service and community musical theater traditions, composers like Scott combined it with European classical and romantic music to broaden its appeal. tatter music, shortened from its original ragged time, is a ripe(p) example of the musical combination of African American style and contemporary ones. The music also was a means of displaying musical dexterity, a talent that lots enjoyed significant success on country wide circuits (Sporre, 2003).The SongWritten in 1902, The Entertainer is a rag time two step both enjoyed as music and for dance. Like other rag time music, it is not a metered piece and can be more appropriately considered as timed by its syncopation. The effect is however is that beats are emphasized even more which encourages movement from the audience. The piece requires that listener begin in tune with the syncopation and drill their movements thusly which encourages the audience to catch the rhythm of the song (French, 2007).The piece is written in the key of C but also has a section written in F. The primary chord pattern in A-B-A-C-D and repetitions become progressively higher in octave. Performers of the piece are given significant margin in its performance allowing for intricate stemma detailing that will become popularized in jazz and rhythm and blues music.For a time, the song was lost to posterity unitedly with ragtime music genre until it regained popularity when it adapted by Marvin Hamlisch for the movie 1973 Academy-winning film The Sting. The track reached the top three on Billboard magazine and since then has become the anthem for the sport of snooker, theme of several television and entertainment productions and a staple of the musical repertoire of musicians (Schafer et al, 1977, pp. 95-101).The Ap pealThe Entertainers appeal lies both in its artistry and its value in culture. The technical aspect of the song reveals a great deal of creative genius and facility in combining musical styles to appeal to a contemporary public (Sporre, 2003). At the same time, it gives insight to the social and cultural development of African Americans in the United States (Schafer et al, 1977, pp. 12-14). Most of all, it highlights the mapping of music in communication and society across races and beliefs overcoming discrimination and bigotry.As much as these perspectives remain important today, so does will the song. Its revival in the 1970s reflects that good music is timeless. Like the people who first heard the tune a hundred years ago, The Entertainer challenges listeners to really listen to it, learning its melody beats and mood. It encourages listeners to experience music and to allow it to move them. For these reasons, The Entertainer fulfills its role not only as a musical piece but als o as a cultural heritage that many generations will continue to love.Works CitedFrench, Christopher W.

Faulty economics Essay

Based on Neoclassical economics, this statement is faulty because the employees provide their bare(a) unit of service by providing the kind of labor that their companies need to their loss of leisure. Almost all CEOs are the most stressed out employees of a come with because they carry the burden to run the company.2. This statement is faulty because the consumers are maximizing their utilities and the producers are maximizing their profits. In this statement, the demand for bottled water is greater than the demand for gasoline. Therefore, the merchandise cost of the bottled water is greater than the production of gasoline.3. Neoclassical economics focuses on the satisfaction of the consumers. Consumers have the preferences on whether they go forth stop smoking or keep open to smoke. Therefore, their addiction to nicotine has no direct relationship with the increase in taxes.4. This statement is not true because the firms go away only employ people when the cost for hiring them is equilibrize with their outputs.5. This statement is not true because the law for supply and demand does not apply to everyday lives. When there is a shortage in parking lots, the university will then put a price in the parking area as the solution to the problem. The students will then bid for their spaces in the parking lots. This is because the university will strive to optimize their market interdependence and to achieve economic equilibrium.

The room access to the presents piano tuner communication ashess was opened by Guglielmo Marconi when he transmitted the three-dot Morse computer code for alphabet S by the purpose of electromagnetic moving ridges over a 3-KM nexus in 1895. This laid the foundation of youthful communicating arrangements runing from political program medium, satellite transmittal and wireless fin whollyy come oning to presents cell phones. It would nt be incorrect to state that wireless communicating has so trans chassisationized our present societyA sudden addition has been observed in the enlargement of wireless carcasss during the last two decennaries. We collapse seen great development in Wireless communicating systems from 1G narrowband par totallyel systems in the 1980s to the 2G narrowband digital systems in the 1990s. Now the bing 3G broadband mul cartridge clipdia system systems atomic number 18 world deployed.

AMPS divided the entire country into little parts called cells and this was from where the construct of cellular telephone started. Cellular Systems had some(prenominal) advantages much(prenominal) as they change magnitude quality, capacity, dependability and handiness of nomadic telephone web. The coevalss of cellular systems be described below.FIRST GENERATION CELLULAR SYSTEMSFirst coevals cellular telephone systems were introduced in 1980 s. They were based on Analog Frequency Modulation proficiency. Each enrapture was assigned a exclusive frequency.First coevals cellular systems offered merely wireless voice service based on parallel engineering. Digital augurs were merely utilize for control information such as dialing a figure etc. These systems were no able to get by with the increasing demands of users besides they had rattling less capacity and provided hapless voice quality.Some first coevalss systems areAdvanced Mobile foretell System, AMPSNAMPS, AMPSEntire Access Cellular System ( TACS )Nordic Mobile Telephone System ( NMT-900 ) sustain GENERATION CELLULAR SYSTEMSSecond generation Cellular Systems provided larger capacity and provided untold better services to users compared to first coevals systems. They were based upon Digital Modulation technique which led to great sweetening in web s capacity.Second Generation Systems use multiple entree techniques such as TDMA and FDMA.The biggest draw back of Second Generation Systems was that its antithetical systems were non compatible with severally other. thitherfore gyre among different systems was non possible.Some of Second Generation Systems areNorth American Digital Cellular, NADCGlobal System for Mobile Communication, GSMPacific Digital Cellular, PDCCDMAONE, I S-95 CDMAIn order to get the better of Second Generation compatibility job with increased information rates of modern cyberspace coatings, 2.5 Coevals criterions were developed. The best thing slightly them was that they allowed already bing Second Generation systems to be upgraded so that they can be utilize for higher information rate transmittal.2.5 Generation brought a new revolution in cellular telephone by back uping services like high velocity cyberspace and location based nomadic services.Some of 2.5 Generation Mobile Systems areGeneral Packet Radio Service, GPRSEnhanced Data Rate for GSM Evolution, EDGEThird GENERTAION CELLULAR SYSTEMSDesigned to supply high quality and high capacity in informations communicating, Third Generation Systems require sophisticated openinging and transition techniques.Third Generation Systems are aimed to supply voice quality comparable to set down line telephone and besides to back up high informations rate.These systems are compatible with circuit switched every bit good as package switched informations services. They are besides compatible with the bing webs and usage wireless spectrum much more expeditiously than earlier.Some Third Generation Systems are broadband CDMA, WCDMAUniversal Mobile Telephone System, UMTSCDMA 2000BEYOND 3GThe extremely developed version of the 3G nomadic communicating are the 4G nomadic communicating services. It is estimated that 4G nomadic communicating services will give addition in capacity, informations transmittal with high velocity, broadband, HQ colour picture images for users, in writing life games in 3D, sound services in 5.1 channels. For the system and architecture of 4G nomadic communicating many researches are done. Developments are make in the terminal protocol engineering for high velocity package services, larger capacity, enabling downloading application plans by public package platform engineering, multimode wireless entree platform engineering, and high quality media co ding engineering over nomadic webs.Why 4G?Servicess like wireless cyberspace and teleconference can be carried by 4G.Global mobility and service portability.Wider bandwidths.Increased differentiate rates.Less expensive.Mobile webs can easy be scaled.Chapter 02 quintuplexing is a procedure in which a individual bearer is utilise to convey several different signals. These several signals are transmitted all together by uniting them and organizing one signal that will efficaciously travel through the bearer bandwidth. When one transmittal is done and the signal reaches the finish point, the incorporate signal re-assembles into its existent signifier and is so get.Multiplexing is one of the most used techniques today in about every communicating system. Because of the technological progress multiplexing, we have seen study addition in efficiency of a broad scope of telephone services and on-line applications.Multiplexing has become an effectual technique that assistances in everyt hing from video conferences and web conferences up to bulk informations transmittals and even doing a childly Point-to-Point phone call.FDMAFDMA is the most usual technique used for multiple accessing. FDMA stands for relative frequency division multiple entree. It is decease from its name that in this technique the frequence is divided among the users as the available spectrum is shared among them in the frequence sphere. The heart signals are transmitted onto bearers for different users utilizing queer RF frequences. Within FDMA structural design the Single roadway Per Carrier ( SPSC ) is the simplest method where each channel is provided with a separate bearer. This scheme finds its kernel in the fact that the channels are assigned on the footing of demand. Within a cell all the channels are available to all users all the prison term, and the channels are assigned as soons as a message signal is received or a petition is made.Guard sets are used to cut down the opportuniti es of discussion from contiguous channels. These fortress sets are present amongst the sets allocated for assorted channels.In the execution of the first parallel cellular systems, FDMA is the multiplexing technique that was used.TDMATime division multiple entree techniques allots different clip intervals to different users for the transmittal of signals and storage of the information is carried out in one frequence channel non like FDMA which uses one frequence per channel.Users are allowed to utilize the aforementioned(prenominal) frequence but the clip slots are divided.In TDMA techniques the available spectrum is divided into little frequence sets as in FDMA, which are farther sub-divided into assorted clip slots. The user can entree the frequence channel merely for clip slot deal to him. User can utilize sporadically the peculiar continuance of clip.In TDMA systems, guard sets are required between both frequence channels and clip slots.SDMASDMA stands for Space-Division M ultiple Access. It is a MIMO ( Multiple-Input, Multiple-Output, a multiple aerial conventional architecture ) based radio communicating web architecture. It enables entree to a communicating channel by the procedure of placing the user location and set uping a one-on-one function between the web bandwidth allocation and the acknowledged spacial location that is why it s largely suited for nomadic ad-hoc webs.For bulk of the well know nomadic communicating architectures such as CDMA, TDMA and FDMA, SDMA architecture can be put together and implementedCDMACDMA stands for economy division multiple entree. CDMA systems are based on the dispersed spectrum technique. In which transmittals by all the users are carried out at the aforementioned(prenominal) time while operating at the equal frequence and utilizing the integral spectrum bandwidth.For the designation and extraction of needed transmittal, each user is allotted with a all(predicate) codification which can non fit with any other user. This issue of designation is due to the fact that all the users transmit at the same time. To procure this privateness, thespian-random noise codifications or PN codifications are used.These codifications are really the extraneous codifications and its advantage is that it reduces the opportunities of transverse correlation co cost-effective among themselves. By utilizing this PN codification assigned to the specific user, transition of the message signal from an single user is done. Then we have the CDMA frequence channel through which all the modulated signals from different users are transmitted. At the receiving system s terminal, the coveted signal is so recovered by de- scatter the signal with a reproduction of the PN codification for the specific user. The signals whose PN codifications are non matched with the coveted signal and are assigned to different users are non de- spread out and as a con instalment are regarded as noise by the receiving system.CDM A differs from both TDMA and FDMA in a manner that it allows users to convey the signal at the same clip and operate at the same nominal frequence so it requires less synchronization whereas in TDMA and FDMA frequence and clip direction is really scathing so more dynamic synchronism is required. One more advantage of CDMA is that complete system s spectrum is used by signals and hence no guard sets are required to protect against next channel intervention.Intro to stretch Spectrum Communications pursuance are the major elements that can clearly depict the Spread Spectrum communicationsBy spread spectrum, bandwidth far in surplus is available than that is necessary to direct the information. Due to this characteristic the transmittal can be protected against intervention and jamming at the same clip supplying multiple entree capableness.An independent codification known as the Pseudo random codification is used for signal spreading across the bandwidth. The distinguishable nature of this codification separates dispersed spectrum communications from typical transition techniques in which transition ever spread s the spectrum slightly.For the recovery of the pilot program signal the receiving system is synchronized to the deterministic imposter random codification. Users can convey the signal at the same clip and operate at the same nominal frequence by utilizing independent codification and synchronal solvent.In order to protect the signal from intervention a pseudo-random codification is used. It appears to be random to anyone who does non hold its pre-defined cognition but in world is deterministic, it is because of this fact that receiving system is able to retrace the codification needed for the recovery of the needed informations signal. This codification used for synchronal sensing is besides called Pseudo noise sequence.Types of Spread Spectrum CommunicationsSpreading of bandwidth of the signal can be achieved by three waysFrequency skipingThe signal is shuffled between different Centre frequences within the full bandwidth available to the hopper pseudo-randomly, and the receiving system used already knows where to look for the signal at a given clip.Time skipingThe signal is transmitted in short explosions pseudo-randomly, and the receiving system knows when a explosion is expected. unionize sequenceVery high frequence is used to code the digital information. The codification is pseudo-randomly generated. The same codification is generated at the receiver terminal, and in order to pull out the superior information this codification is calculate to the received information watercourse.Beginning cryptanalytics AND DIGITAL MODULATION3.0 IntroductionDigital Modulation is performed in order to stand for digital informations in a format that is compatible with our communicating channel.Why Digital Modulation? Digital transition strategies have greater capacity to convey big sums of information than parallel transition strategies .3.1 DIGITAL DATA, DIGIITAL SIGNALDigital signal is binary informations encoded into signal elements. Different convert strategies for encoding digital informations into digital signal are3.1.1 Non Return to Zero ( NRZ )In NRZ there are two different electromotive force degrees for 0 and 1. There is no passage in the focalize of the spot. The absence of signal denotes 0 and a positive electromotive force degree denotes 1.The major drawback of NRZ strategy is that it adds a dc constituent to the signal.3.1.2 Multilevel Binary ( AMI )In this encoding strategy there are more than two degrees. No signal represents 0 and 1 is represented by some positive and negativeThere is no dc constituent in this strategy and besides there is no loss of synchronism for back-to-back 1 s.3.1.3 Manchester CodingThere is passage in nerve of each spot, which acts as a clock every bit good as informations. The low to high passage represents 1 and high to low represents 0.3.1.4 differential ManchesterIn this scheme passage at the center of the spot represents merely timing while passage at start represents 0 and no passage at start represents 1.3.2 ANALOG DATA, DIGITAL SIGNALAnalog informations is foremost converted into digital informations by utilizing parallel to digital convertors. These convertors use different techniques to finish their undertaking, some of them are3.2.1 flash Code ModulationIf a signal is sampled at regular intervals at a rate higher than twice the highest signal frequence, the samples contain all the information of the original signal. Each sample is assigned a digital value. Although its quality is comparable to that of parallel transmittal but still in this procedure some information is lost and the original signal can neer be recovered.Delta ModulationAnalog insert is approximated by a stairway map. Function moves up or down at each sample interval by one degree ( vitamin D ) .Delta transition is easier than PCM in execution, but it exhibits worse sig nal to resound ratio for the same information rate. But it is good for informations compaction.DIGITAL DATA, ANALOG SIGNALDifferent digital transition techniques areAmplitude Shift Keying ( ASK )A transition technique in which digital information is represented as fluctuations in the bountifulness of a bearer moving ridge is called Amplitude-shift keying ( ASK ) . One binary figure is represented by heraldic bearing of bearer, at changeless amplitude and the other binary figure represented by absence of bearer.3.3.2 Frequency Shift Keying ( FSK )In frequence displacement identifying different frequences are used to stand for incoming digital information. Say in subject of Binary Frequency Shift Keying f1 is used to stand for 0 while f2 is used to stand for 1.In MFSK more than two frequences are used and therefore bandwidth is more expeditiously utilised.3.3.3 Phase Shift Keying ( PSK )A digital transition technique in which information is transmitted by modulating and altering th e stage of the mention signal is called Phase-shift keying ( PSK ) . In instance of PSK, a finite figure of stages are used. A alone form of binary spots is assigned to each of these stages. By and large, each stage encodes an equal figure of spots. The symbol is formed by each form of spots that is represented by the peculiar stage.The bandwidth of ASK and PSK are specified asWhereas the bandwidth of FSK is given asWhere,Roentgen is the spot rateDF = f2 fc = fc f1Chapter 04CHANNEL Cryptography4.0 IntroductionWhy Channel Cryptography? In modern digital communicating systems information is represented in spot watercourses, which are so modulated to analog wave forms before being transmitted onto a channel. At receiving system this parallel information is demodulated into spot streams, but because of the presence of intervention and noise in the communicating channel this spot watercourse may be corrupted. So to minimise happening of spots in mistake and protect digital information from channel noise and intervention channel cryptography is used.How Channel Coding is performed? Additional redundant spots are added to the message informations watercourse to execute channel cryptography, these excess spots assist in mistake sensing and rectification at the receiving system s terminal.Channel Coding at the cost of? Channel Coding is performed at the cost of bandwidth enlargement and information rate decrease.4.1 TYPES OF CHANNEL CODING TECHNIQUESThere are two chief types of channel coding techniques,Block CodesConvolutional Codes.Block Codes accepts thousand figure of information spots and bring forrader a block of n figure of encoded spots, and therefore are normally known as ( n.k ) block codifications. Some communal illustrations of block codifications are Overacting Codes and Reed Solomon Codes.Convolutional Coding is frontward error rectification technique that is presently most widely used in modern communicating systems, this peculiar technique is used for real-time mistake rectification. Unlike block codifications which append excess spots at the terminal of original message signal, Convolutional coding organize a new codeword utilizing original informations watercourse. The encoded spots are non entirely dependent on K current input spots but at the same clip on case in point input spots.4.2 CONVOLUTIONAL CODESIn this undertaking Convolutional Coding is implemented. Convolutional Codes are farther classified as 1. treillage Coded Modulation ( TCM ) 2.Turbo Codes.Trellis Coded Modulation ( TCM ) is non recursive, non systematic and does non necessitate an interleaver.Turbo Codes on the other manus are recursive, systematic, parallel structured and they besides require interleaver.In Wideband CDMA systems TCM is used for all channels while Turbo Codes may be used for DCH and FACH channels. Turbo Codes are sometimes classified as separate subdivision of Channel Codes so from here onwards word Convolutional Code will merely be used for TCM.Types of Transmission ChannelsConvolutional Cryptography1/2BCHPCHDCH, FACH1/2, 1/3Turbo Coding1/34.3 CONVOLUTIONAL CODE REPRESENTATIONS4.3.1 Polynomial RepresentationNo. of input information spots = KNo. of encoded spots = NsNo. of phases ( Constraint Length ) = KCode Rate = k/nEncoded CodeWord = UThe undermentioned illustration shows how Convolutional Codes are represented.Let g1 ( x ) and g2 ( ten ) be encoder multinomials, whereg1 ( x ) = 1 + x + x2g2 ( x ) = 1 + x2Let input message spot stream be 101, hence input message spot stream multinomial will be,m ( x ) = 1 + x2The encoded codeword U will be combination of merchandise of g1 ( x ) with m ( x ) and g2 ( x ) with m ( x ) ,m ( x ) x g1 ( x ) = 1 + 1.x + 0.x2 + 1.x3 + 1.x4m ( x ) x g2 ( x ) = 1 + 0.x + 0.x2 + 0.x3 + 1.x4Therefore the codeword U , becomesU = ( 1,1 ) + ( 1,0 ) .x + ( 0,0 ) .x2 + ( 1,0 ) .x3 + ( 1,1 ) .x4U = 1 1 1 0 0 0 1 0 1 14.3.2 State Transition DiagramConvolutional Coding can be represented utilizi ng State Transition Diagram. Following are State Transition Diagram and State TransitionAgain for the same input spot stream 10100, the codeword U = 11 10 00 10 11. In the input message last two 00 spots are tail spots.4.3.2 Block Diagram RepresentationThe undermentioned diagram shows block diagram commission of Convolutional Coding withCode Rate = 1/2Constraint Length ( No. of Stages ) = 3The undermentioned illustration illustrates the procedure of Convolutional Coding utilizing block diagram representation for input spot stream 101.So the concluding codeword becomes, U = 11 10 00 10 114.3.2 Trellis Diagram RepresentationFor input spot stream 101, the followers diagram shows how Convolutional Coding is performed utilizing Trellis DiagramChapter 05PULSE SHAPING TECHNIQUES3.0 IntroductionWhy Pulse Determining? It is done in order to cut down Inter attribute psychological disorder normally known as ISI.How Pulse Shaping is performed? In order to accomplish goose egg-ISI the ove rall system response must be equal to Nyquist frequence response.5.1 RAISED COSINE FILTERInter Symbol Interference significantly degrades the informations sensor ability to distinguish between a current symbol from diffused energy of next symbol. This leads to the sensing of mistake and increases BER. So in order to provide ISI, a real-time realisation of Nyquist filter is applied in modern communicating systems. increase cosine filter is one of the realisation of Nyquist filter.where R = roll-off component part = 1 ? R ? 0and T = symbol period = 1/RRoll-off factor determines the filter bandwidth and represents a tradeoff between the acuteness of the passage set of the filter and impulse response pealing magnitude of the filter.A Nyquist filter has following belongingssTime response finally goes to zero in a clip period on the nose equal to the symbol spacing.By trying the symbol sequence at a given symbol clip point, present symbol is non affected by the energy distributing fr om the next symbols.The impulse response and the frequence response of the RC filter isTime response of the RC filter goes to zero with a period that precisely equal to the symbol spacing. As the response equals zero at all symbol times except for the coveted one none of the next symbols interfere with each other.5.2 ROOT RAISED COSINE FILTERRC filter is divided into a blood system raised cosine ( RRC ) filter brace, with one at the transmitter terminal, which performs the pulsation defining in order to restrain the modulated signal bandwidth, and the other at the receiver terminal, that performs matched sensing for optimising the SNR of a known signal in AWGN presence.The starting time Raised Cosine filter is so named because its transportation map precisely is the square understructure of the transportation map of the Raised Cosine filter.Where R = roll off factor and T is symbol period. The RRC filter bandwidth is equal to the root mean square ( RMS ) amplitude 2R.The impulse response and the frequence response of the RRC filter isBoth RC and RRC have similar pulsation forms, but the RRC pulsation makes slightly faster passages, therefore the spectrum of RRC pulsation decays more quickly every bit compared to the RC pulsation. Another of import difference between both pulsations is that the RRC pulsation does non hold zero Inter Symbol Interference. Because of the fact that RRC filter is used at sender and receiver both, the merchandise of these transportation maps is a raised cosine, which will ensue in zero ISI end product.5.3 ROLL OFF FACTORThe roll-off factor, R, is a step of the extra bandwidth of the filter, i.e. the bandwidth occupied beyond the Nyquist bandwidth of 1/2T.Where a?f is extra bandwidth and Rs is symbol rate.Chapter 06SPREAD SPECTRUMSpread spectrum is a type of transition where the information is spread across the full frequence spectrum. This procedure of distributing the information across the full spectrum helps signal against n oise and intervention. These techniques are largely employed in cell phones and besides with wireless LAN s.To measure up as a spread spectrum signal, two specimens must be metThe familial signal bandwidth must be in surplus of the information bandwidth.Some map other than the informations being transmitted is used to set up the bandwidth of the partner transmittal.Why Spread Spectrum?Due to its sole and curious belongingss spread spectrum is preferred over other transition strategies. Some of these belongingss are characterized as advantages and disadvantages of a basic spread spectrum system below.Advantages It reduces the effects of multipath intervention and at times removes them wholly. Frequency set is shared at the same time with other users. Pseudo random codifications guarantee protection of transmittal and privateness. As the signal is spread over an full spectrum it has a low power spectral denseness.Disadvantages Due to distributing operation it consumes more bandwidth . It is at times hard to implement.Types of Spread Spectrum TechniquesMost normally used techniques in a spread spectrum systems areDirect Sequence Spread SpectrumFrequency Hoping Spread SpectrumFrequency Hoping Spread SpectrumA frequence skiping dispersed spectrum hops from one narrow set to another all within a wider set. In general the frequence hopper sender sends informations packages at one bearer frequence and so leaps to another bearer frequence before directing ore packages and continues the same modus operandi throughout the period of transmittal. The form that emerges seems to be random but is in fact periodic and easy traceable by pre configured sender and receiving system. These systems can be vulnerable to resound at a peculiar hop but normally are able to direct packages during the following hop.Direct Sequence Spread SpectrumMost widely used technique of spread spectrum is the Direct Sequence Spread Spectrum. A Direct Sequence Transmitter receives the entrance inform ations watercourse which is to be transmitted and so change over it into a symbol watercourse where the size of a symbol can be one or more spots. Using any of the transition strategies for digital systems such as Quadrature Amplitude Modulation ( QAM ) or Quadrature Phase Shift Keying ( QPSK ) this symbol watercourse is cypher to a noise like sequence known as imposter random sequence. It is besides know as a bit sequence. As a significance of this generation the bandwidth of the transmittal is significantly increased.Figure 3. Direct Sequence Spread Spectrum SystemFigure 3. shows the working of a basic Direct Sequence Spread Spectrum system. For lucidity intents, one channel is shown working in one way merely.TransmissionFor each channel a distinguishable and different Pseudo random codification is generated.In order to distribute the informations the information watercourse is multiplied with the antecedently generated Pseudo random codification.The signal obtained as a consequ ence of this generation is so modulated onto a bearer.This modulated bearer wave form is so amplified before broadcast medium.ReceptionThe bearer moving ridge is amplified every bit shortly as it is received by the receiving system.The signal received is so multiplied with a locally generated bearer which gives the spreaded signal.Again a Pseudo random codification is generated on the footing of the signal expected.The procedure of coefficient of correlation is carried out on the standard signal and the generated codification which gives the original message signal.Pseudo-Random NoiseThe spread spectrum systems are constructed really similar to other conventional systems. The difference being the add-on of pseudo random generators both at the sender and the receiving system which generate the Pseudo noise sequences required for the functionality of Direct Sequence spread spectrum. These pseudo random noise sequences are used for distributing the signal at the transmitter side and d ispreading at the receiver side. A pseudo noise sequence is made up of a figure of symbols which are called french friess. It is imperative that a good codification is selected for its type and continuance straight affects the system capableness.A alone codification is generated for each channel. All the transmittals for a peculiar user are so added together. At the receiving system each user generates its ain matching codification in order to retrieve the original signals.In order to measure up as a imposter random codification and proper functionality a codification must hold the undermentioned belongingss.The imposter random codification must be deterministic so that the receiving system can bring forth the exact codification as used by the senderIt should be random for any hearer who does non hold the cognition of the codification being used so that it appears as noise to any interferer or eavesdropper.Two codifications must be indistinguishable and have no or really little re levance to each other.The codification should non reiterate shortly there must be a long clip before that happens.Maximal space sequencesMaximal Length sequences can be generated by the aid of displacement registries with feedback applied on them. These sequences meet all the conditions for distributing sequences really purely. The cross correlativity between this sequence and noise is really low, which helps in observing signal out of noise in the receiving system. These sequences are really utile for encoding as they besides have a really low cross correlativity with each other.The entropy belongingss of maximum length sequences can be seen here.Gold SequenceIn order to make two gold sequences, two maximal length sequences are to be combined. They have a really low auto-correlation which enables CDMA systems to convey asynchronously. Gold sequences are constructed by modulo-2 add-on of two maximum length sequences of same length chosen from braces of preferable m-sequences.Walsh CodesWalsh codifications have to be created from hadamard matrices. All generated Walsh codifications would be extraneous to each other. The basic hadamard ground substance is shown below. These sequences provide low cross-correlation between each other. Second, the figure of 1 s is same as the figure of 1 s in each codeword.By looking at the matrix above, Walsh codes with different lengths can be generated with the aid of recursion. For a clear apprehension Walsh codes with length equal to 4 are illustrated below.=Spreading the SignalSignal spreading is achieved when the signal is multiplied bitwise with the imposter random sequence. Figure 4. Below gives an penetration into how two spots are multipliied to a pseudo random sequence holding a length of 8 and the its corresponding consequence on the frequence spectrum. Spreading procedure of two spots with the aid of an 8-chip PN sequence is shown on the left side and the consequence of this distributing on the signal s frequence sp ectrum is shown on the right side of figure. 4Figure 4. The rule of signal spreadingDe-spreading the SignalDe-spreading of the signal is carried out by multiplying each spot of the signal to its correspond imposter random codification and the consequence is summed bitwise. Figure 5. describes the procedure of de-spreading when a imposter random signal of length 8 is used for transmittal and the de-spreaded signal is equal to the dispersed signal. De-spreading procedure of two spots with a PN sequence of 8-bit is shown on left side and the consequence of the de-spreading on the signal s frequence spectrum is shown on the right.Figure 5. The rule of signal de-spreadingConsequence of Spreading on BandwidthFigure 1. As a consequence of distributing operation the signal s frequence is spread over a wider bandwidthSpread spectrum transition is applied in tandem with some other digitial transition strategies such as QAM or QPSK.Consequence of Despreading on BandwidthFigure 2. The despreadi ng operation recovers the original signal.A spread spectrum transition is applied in coherency with a conventional demodulation process in order to retrieve the original signal.Multiple Access CapabilityThe standard signal s1 is detected by the receiving system summed with the other signal s2. The signal s1 which is for user 1 is merely extracted at the receiving system for user 1 whereas the signal s2 appears to be as noise in comparing to the user 1 signal s1. This is shown in Figure 6. belowFor efficient recovery of the informations from user 1 it is must that the signal appearance as noise has adequately low energy in the information bandwidth of signal s1.Spreaded informations multi-usersDe-spreaded informations multi-usersSpreaded informations multi-usersDe-spreaded informations multi-usersFigure 6. Multiple Access Capibility when user 1 recovers signal s1Chapter 07DESIGN OF A CDMA BASED COMMUNICATION SYSTEM7.1 THE Sender7.1.1 Source EncodingIn order to do incoming message co mpatible with the communicating system beginning cryptography is used. In this undertaking NRZ encoding strategy is used so that the incoming message signal becomes compatible with the walsh codifications which are besides in NRZ signifier. NRZ encoding provides a better use of the bandwidth, besides if we compare it with AMI strategy it is more efficient because in that receiving system has to separate between three different degrees and it requires more signal power. While the Manchester and differential Manchester strategies have transition rate twice or more than that of NRZ so therefore they require greater bandwidth.7.1.2 Channel EncodingChannel encryption is performed so that spot mistakes can be reduced at the receiving system besides it protects the information from channel noise and intervention. In this undertaking we have used Convolutional Encoding technique and so hold tried to upgrade our system utilizing Low Density Parity Check ( LDPC ) . LDPC improves channel capa city as it approaches to Shannon capacity bound. Both Convolutional encoder and LDPC encoder organize a codeword based on the incoming message signal. We have used ? rate encoders that means that we have two input spots and the end product is traveling to be four spots. For Convolutional encoder inbuilt matlab treillage construction along with convenc declare oneself has been used while in instance of LDPC fecldpc.enc bid is used to do LDPC object utilizing thin H matrix and so message is encoded utilizing LDPC object by encode bid.7.1.3 SpreadingThe cardinal standard of spreading is transverse correlativity and car correlativity of message symbols. In instance of a CDMA based communicating system as there are many users that at the same time transmit informations so the system must hold good cross correlativity belongingss. This generates the demand of extraneous codifications so Walsh codifications are used. Walsh codifications have good cross correlativity belongingss. In this u ndertaking direct sequence spread spectrum ( DSSS ) technique has been employed to distribute the signal across the full bandwidth.7.1.4 Digital TransitionTransition is a technique that facilitates the message signal to be transmitted over the medium. In instance of digital transition, digital signal is modulated utilizing amplitude displacement keying, frequence displacement keying and stage displacement identifying etc. We have implemented Binary PSK, BPSK uses two symbols that have opposite stage to each other to modulate 0 and 1.Sampling frequence of 44 kilohertzs and a information rate of 2 kilohertz has been used in this system. In instance of LDPC modulate bid has been used to modulate the signal.7.1.5 Pulse DeterminingThe consequence of inter symbol intervention ( ISI ) is minimized by the aid of pulse determining procedure. In this undertaking Root Raised Cosine Filter has been used at the transmitter side to determine the pulsation so as to restrict the bandwidth of the mo dulated signal. By utilizing this technique bandwidth is limited but the signal spreads in so there must be a threshold in order to counter this job, this threshold is known as Nyquist bound. It is fundamentally a low base on balls filter with a axial rotation off factor 0.5 which has been used in this undertaking.7.1.6 Symbol PackingIn symbol wadding, a preparation sequence is appended at the start and terminal of the signal. Besides in add-on to this about 1000 nothings are inserted at the terminal and start of the signal. These are added so that even if the receiving system fails to have initial spots these spots are extra nothings and non the message signal.7.2 THE CHANNELIn a communicating system channel could be wired or wireless. Different channels have different features. When of all time we lambast about a channel we talk about noise, it is fundamentally the unwanted electrical signal that confines the receiving system ability to take right determinations. Channel noise de grades the end product really rapidly. Small channel does nt do much difference to the end product signal but big channel noise well degrades the signal. In instance of little channel noise the lone noise that is present in the system is quantization noise. Another of import factor in a communicating system is Inter symbol intervention ( ISI ) . When the channel bandwidth is non much greater than signal bandwidth the spreading of the signal causes ISI.Normally, the radio channel is modeled with AWGN channel. A thermic noise beginning is used to distribute an equal sum of noise power per unit bandwidth over all frequences that is the ground why a simple theoretical account for thermic noise presumes that its power spectral denseness Gn ( degree Fahrenheit(postnominal) ) is level for all frequences, as is denoted asGn ( degree Fahrenheit ) = N0/2 watts/hertz7.3 THE Receiver7.3.1 SynchronismIn this system, it is assumed that the receiving system is on all the clip. Therefore whenever t he sender will direct the message signal, there should be some manner through which the receiving system can find where its signal of involvement is. This can be done by correlating the preparation sequence with the standard signal. The portion where the maximal correlativity occurs would be the start of the signal and the 2nd upper limit in the correlativity would give the terminal of the message signal.7.3.2 Matched FilteringThe standard signal is passed through root raised cosine filter in order to execute matched filtering and down trying at the receiver terminal. Normally RC filter is divided into a root raised cosine ( RRC ) filter brace, with one at the transmitter terminal, which performs the pulsation defining in order to restrain the modulated signal bandwidth, and the other at the receiver terminal, that performs matched sensing for optimising SNR of a known signal in AWGN presence.7.3.3 DemodulationThe signal is demodulated by multiplying it by the bearer signal. The end product would be demodulated signal, but this demodulated signal would be sum of all the spreaded signals.7.3.4 DespreadingIn order to pull out the single message signal of each user, the spreaded signal is so once more multiplied by the Walsh codification and is so integrated over a symbol clip.7.3.5 Channel DecodingIf the channel cryptography was non employed by the sender, so the despreaded messages would be the standard signals. In the channel coding instance, the signal will hold to be decoded by utilizing the viterbi decrypting map in matlab.7.3.6 Source DecodingWhile executing beginning cryptography we had used NRZ encoding strategy, so now at the receiving system this encoded message is once more decoded back to its original signifier.

Electoral College System Essay

The President and the delinquency President of the United States ar choose indirectly by an institution known as the electoral College. The U. S. Constitution provides the broad framework through which electors are appointed and by which they cast votes for the President and Vice President. In evaluating the contingent upon(p) election process, near commentators have suggested that any threshold inquiry requires assessing how often contingent election occurs. If the results of a general election are condescendly inconclusive, they increase the likelihood of contingent election.The democratic criteria require implementing reforms that bring the people into the contingency process. Critics of the electoral College governing body argue that the presence of viable and well-funded third- society or independent presidential campaigners, who may be able to garner electoral votes by carrying a plurality of the votes in severalisewide elections, increases the likelihood of contingen t election. psychoanalysis of criticism of the Electoral College system There are several shortcomings of the Electoral College as cited by the proponents of the presidential election reform.These shortcomings have raised justifications for reform or abolition of the current system. One of the criticism is on the Electoral College is the Electoral College deadlock of the contingent election. In this one, the 12th amendment provide that the House of Representatives should choose a president and the senate chooses the vice president by contingent election if the presidential and the vice presidential candidates votes have not reached a simple volume of the Electoral College votes.The election of the president by the House of Representatives happened only once on the February 9th, 1825 where John Quincy Adams was elected as President over Andrew Jackson. This election was criticized by some commentators saying that it brought about a geological formational crisis since the president was selected as part of a political corrupt bargain because some of the presidential candidates were disqualified from the contingent election. Critics claim that this election removes the choice of president and vice president voters (Whitaker & Neale, 2004).Another criticism is on the minority president which was expressed in the Electoral College misfire. In this one, the current electoral college system can result in the election of a minority president which states that the president can be one who wins the major(ip)ity of the electoral votes even though he has lost the popular votes. This was experienced in the 1800s where three minority presidents namely, John Quincy Adams in 1824, Rutherford B. Hayes in 1876, and benzoin Harrison in1888.The other criticisms are on the current methods of allocating electoral votes, the decennial census problem, and the faithless elector, presidential succession between nomination and inauguration, independent and the third party versus majo r party candidates. These criticisms have caused so many controversies that have made many people believe that the current Electoral College system is not a unspoilt system and therefore it needs amendment (Whitaker & Neale, 2004). Advantages of various reform proposals.The electoral college reform proposals include (1)the district plan, awarding each state two at greathearted electoral votes to the state-wide popular vote winners, and one electoral vote to the winning candidate in each congressional district (2) the proportional plan, awarding electoral votes in states in direct proportion to the popular vote gained in the state by each candidate and (3) the automatic plan, awarding each states electoral votes directly on a winner-take- all basis to the statewide vote winners (Amar, 1995).The advantages to the electoral-vote system include its tendency to produce a give the sack winner. The constitution is however subject to change, allowing for the second vote in case of depres sed voter turnout. Great leverage is also given to third party candidates by requiring the winner to have a majority and by this it calls for fair and just elections. A National Election Agency is incorporated in the system to run the vote. However, the government also comes in to help, where the National Election Agency has fewer powers under the government (Amar, 1995).Despite the fact that the president alone is elected by the people, doesnt mean he can permitly defy the law. It is good to know that the elections are fair in that a presidential candidate who stands in his campaign and wins with a substantial majority of votes from the American people does of course gain the mandate. The candidate who emerges with the most electoral votes has a fully legitimate claim to the office for the next four years (Amar, 1995). Disadvantages of various reform proposals. In the U. S there is a rule that, a candidate elect on the Election Day may not be the president.Therefore if it happen s that a candidate has failed to win the national popular vote, he might be sworn in as the president by the virtue of claiming more electoral votes on than his opponents. Therefore the master(prenominal) disadvantage of such kind of proposal, is that if the academic term president who lost in the popular vote is returned again to power after his rejection, then there will be a wide chiding on the Electoral college as a wacky anachronism which will lead to extensive demands for the amendments of the constitution in order for the replacement of the electoral vote with popular election (Longley, 2008).Due to this kind of proposals, there is a possibility of not telling the exact winner since the constitution is the main source of authenticity. The main disadvantage here is that there might be a possibility of both candidates having different fundamental campaigns which give different issues of emphasis and making frequent appearances in different states. Another disadvantage for th is proposal is the argument on which candidate to take office and who was chosen by an archaic and wholly ill-judged system.If the electoral system is replaced, by the popular vote election, since it is not irrational there is a possibility of embarrassment on the president opting to be chosen by this process (Dellinger, 2004). Another greatest disadvantage of the present system of voting in U. S is that there is a possibility that the candidate who receives the most votes from the nation (people) may not take office. Therefore the present president in office may face many challenges and offsetting values since he or she was not put in by the majority.The disadvantage of the constitutional system for choosing a president in the U. S is not perfect and needs to be changed and therefore the candidate who emerges with most electoral votes has full justified claim to the office for four years (Dellinger, 2004). Conclusion It is clear that once the candidate chosen by the people of the United States on the Election Day may not become president. The candidate must choose the constitutional rules currently in place.In the voting parties, the party that receives more total votes nationally wins the parliament while the one with fewer total votes chooses the Nations prime minister. The constitution however, is subject to change (Longley & Dana, 1992). Amending the Constitution to alter it would present a series of difficult questions Will we give great leverage to third party candidates by requiring the winner to have a majority? Will we have a runoff, which might lead to depressed turnout for the second vote? Will we pee-pee a National Election Agency to run the vote and or leave it with the 51 governments who now run it?If those states report raw votes, will they in some manner artificially increase the number of voters in the state or pad the totalsa temptation now avoided by having a set number of electoral votes for each state? These are not insurmountable obje ctions to constitutional change, but they should certainly give pause (Longley & Dana, 1992).ReferencesAmar, A. R. (1995).

Business Essay

Many companies, especially SMEs, have a management that leaves much to say in its management, neglecting many aspects that cannot be ignored again before the commitment to ensuring a productive performance, which may lead to the expected results obtained and properly established in its objectives and mission. When you jeopardise into them is detected organizational misbehaviour manifested in a climate that leaves a lot to say and where the internal work environment is polluted with many flaws that take up damage.Hence, the need to go into assessing what the reality of the work environment, how it works, its impact and that is being done. Management must always be vigilant in ensuring good organizational behaviour, a climate that is favourable and security to the company under its charge of its operation, achievements, successful participation in the markets in which it operates. Thus, one cannot neglect how he handles the internal working environment, be aware of the proper use of their resources, how the technology is used, the operation of production systems, quality management, performance manuals, discipline and commitment to work, ergonomics, leadership, communication to name a hardly a(prenominal) aspects.Types of Organisational Misbehaviour About this reality that is much in companies in the coun chastise, in industries, where many companies have neither guarantee a good working environment, significantly pushing its functionality, operability, and forces neglected to tend to avoid negative effects. Comment, no doubt, that this situation creates a lot of stress and anxiety, and it affects not only professionally but as well in other areas of our life. The ideal thing is to change as soon as possible to run out of that kind of environment.Although there are quantify when you prefer to lose hold that simply do not work because we can afford it (but please, get out when you can, do not have to decease at least eight hours a day as well). If that is the case here and you really cannot leave work, and then at least try to make it more supportable. Here are some things you can do1. Stay away from negative people who is always complaining or criticizing, youre calmer. Of course there are times you cannot, but try your best because these people are typical emotional vampires that leave you exhausted. 2. Creating a custom workstation and relaxing (with photos, flowers, etc). So you will feel at ease at least in that space. You can also listen to music or isolate a bit with headphones. 3. Doing good work. Ive said before when you work thoroughly and do things the best you can feel very good. 4. Keeping busy. If we do our patronage we will, because if dissatisfaction joins apathy, boredom and apathy, not get very far. 5. Think if anything you can do to improve the situation. Lest were complaining and basically can do something about it. perchance if we strive to meet our fellow some would be more relaxed atmosphere and friendly, f or example. So if there is no solution at least make it bearable and acceptable as possible. What do you think?Conclusion It is up to everyone to watch in all matters in which we interact, determine how this affects our character, behaviour and not let anything affect us, we are able to make the right decisions to avoid being caught us in anything we atmospheres benefit, we simply do not allow the search for solutions and that suits us.

Effect of Force and Mass on Acceleration Essay

Abstract In this lab there were cardinal principals investigated. The first was the family among applied thrust and quickening. The second was the relationship between kettle of fish and acceleration. To study these two relationships, my partners and I used a dynamic cart with added mass on it. This cart was wherefore attached to a pulley outline on a frictionless track where it was pulled by a force bearing mass over the edge of a table. In the first relationship tested, applied force and acceleration, mass was moved from being on the cart to being on the end of the pulley. My partners and I measured the acceleration with the LabQuest information processing system every time the cart was released. In monastic order to test the relationship between mass and acceleration, my group added different amounts of mass to the cart and measured the salmagundis in acceleration. From all of the selective information collected we concluded that force and acceleration have a direct, linear relationship. We also go underd that mass and acceleration have an inverse, quadratic polynomial relationship.Background When my lab partners and I started this lab, we came in knowing some background information on what we were doing and the concepts involved. We knew that we had to determine the relationships between acceleration in a system and the crystalize force performing on the system. We also knew that we had to discover the relationship between acceleration and mass in the system. Some major concepts we had to understand introductory to the lab were Newtons Fist Law of Motion, acceleration, net forces, and inertia. Newtons first law states that an object at rest will lie at rest, and an object in motion will remain in motion, with the same speed and direction unless acted on by an unbalanced force. This is important because we were conscious(predicate) that when an object is moving at constant velocity there is a net force of zero.This gave my group our basic understanding of acceleration, a rate of change of velocity over time because we realized that when there is an unequal net force the object must be accelerating/ decelerating. This also allowed my group to understand how net forces work, which is especially important since this lab consists of net forces that are not zero. Because the track the cart rode on was considered to be frictionless, my group used our prior knowledge to sop up that the only unbalanced force in the system was from the horizontal tension in the drawing string. My groups understanding that inertia is an objects tendency to stay at rest and withstand motion helped us during the lab as well. With this background knowledge we were able to perform the appropriate experiments to gain the correct results for our lab.Purpose The purpose of this lab was to determine the relationship between mass and acceleration. Another purpose was to determine the relationship between the acceleration in a system and the net for ce that is acting on the system. We wanted to deepen our understanding of these relationships by proving already known theories for ourselves.Hypothesis If the mass of the cart is kept constant but the net force of the system increases (hanging weight over the pulley), consequently the acceleration will increase. The acceleration will increase because a larger force will cause the object to move faster. This is because as the forces become more unbalanced in the horizontal axis the easier it is for an object to overcome its inertial tendency to stay at rest. However, if the mass of the cart changes but the force is kept constant, then the acceleration will decrease. This will happen because the heavier the object is the more force needed in order for it to move. Adding mass would increase the objects inertial tendency to stay at rest.Lab DrawingProcedure To test the relationship between acceleration and force (constant mass) my lab partners and I set up a metal cart on a metal fric tionless track. The cart had a string attached to it that ran over a pulley, alongside the edge of the table, where it was connected to a hanging mass (as the above drawing indicates). We hooked up a LabQuest entropy logger to the track in order to document the carts acceleration while being pulled by the hanging weight. My lab partners and I then placed two ergocalciferol gravitational constant blocks on the cart in addition to five 50 gram masses. On the end of the string hanging was a 50 gram mass. The cart was then released from its held position on the track, and the hanging weight caused the cart to accelerate. This acceleration was documented by the LabQuest data logger. My partners and I performed three trials and then found the average acceleration.Once the average acceleration was calculated, we took a 50 gram mass from on top of the cart to the hanging mass. The cart was released and the LabQuest data logger documented this new acceleration. We did this three times as w ell. My partners and I did this until all of the 50 gram masses were transferred from above the cart to onto the hanging string (6 different forces, 15 different trials). After this was completed we found the applied force by multiplying the hanging mass by 9.8 m/s2 (acceleration due to gravity). We then plotted the points and graphed the data to discover the relationship.To test the second relationship, mass and acceleration, my lab partners and I used the same cart and pulley set up on the frictionless track. We calculated the mass of the cart prior to adding any more mass, which was about 500 grams. Once we discovered this number we added five 500 gram masses to the cart. We released this cart three times, using a constant force, and had the LabQuest document the acceleration. We then found the average acceleration for the 3 kg cart. After, we removed iodin 500 gram mass from the cart. We released the cart three times with this new mass and found its individual and average accel eration. We repeated these steps until all of the 500 gram masses were removed from the cart, and then tested the cart with no added mass (6 different masses, 18 different trials). Once completed, this data was plotted and graphed, and the relationship determined.

Prison Nursing Essay

I had been a nurse for 1 yr, and only plumped in hanker term care. I craved a change in my career that was exciting, yet challenging I decided to become a correctional nurse. I had no idea what was in store for me when I applied for a position with UTMB . I spoke with family and friends who thought I was crazy for wanting to encounter in such a hostile environment. Needless to say, I didnt listen and followed my own instinct. When I was hired, I had not taken a tour of the facility day one was the first clip I walked into a prison. As I walked in the gate house, I was saying to myself this isnt so badI kept telling myself those same words the whole time I was fetching my shoes off , letting my hair down to be searched, and bulgeting frisked while checking for contraband. After the closely violating pat down I had ever received was over, my heart began to pound. What am I getting myself into? at once in the infirmary I was given a brief description of job duties. By promptly my heart was in my throat, but I kept up the brave front . I learned that I would be working in our clinic with convicts that required inpatient health check care. My role was to provide breast feeding care only. A few things I had to take into consideration they were convicts.They could be quite manipulative and they move to test me every(prenominal) time I turned around. They takeed questions about my personal life and they asked for favors. They would also ask me to bring in things from the real world or deliver items or letters. This behavior could be intellect for termination so any and every time I was asked to do any of the things I listed or anytime an inmate tried to get to personal it had to be reported. The inmate would then have to face corrective action. It was very hard to remember all the dos and donts while maintaing professionalism, as well as maintain safety and sanity.In the Texas prison system the inmates endure grueling conditions. In the winter its free ze cold, old boilers are all they have to keep warm. In the summer its smoldering hot, old creaky fans are all they have to keep cool. Being tender hearted as I am, I couldnt help but feel sorry for them. I was raised to see the good in every body. I was also raised to believe in an eye for an eye. It was really hard to provide impartial care when I knew I was dealing with a child molester or a rapist. I accredit we were trained to put all our emotions aside, but in reality my emotions would sometimes get the best of me.I only worked as a correctional nurse for a yr. I enjoyed working with other members of the medical staff as well as correctional officers. I actually enjoyed working with the inmates, providing medical care. I have had my share of inmates cursing and yelling at me and have witnessed situations I will never forget. I learned very quickly to be thick-skinned. I learned to be tough in auberge to do the job and survive. I still reminisce about the adrenalin rush I w ould get every time and emergency would arise. Im glad I made the choice to work at the Wynne Unit it was definitely a life changing experience.

Love and War in Tim O’Brien’s The Things They Carried Essay

In The Things They Carried, as the title indicates fountain and Vietnam war veteran Tim OBrien business organizationfully describes all(prenominal) of the necessities of warfare carried by the men with whom he dual-lane the war. In addition to the weapons and gear necessary for survival they carried within themselves the images and memories of home. OBrien describes the various articles carried by individuals as well as the heavier items they would take turns carrying. The heaviest were the things men carried inside (25). Because of the heaviness it was often too much for maven man and they shared the weight of memory. They took up what others could no longer bear (14). OBrien indicates the heaviest memories were of love ones, specially wives and girl mavins. Obrien describes the characteristics of the memories of love in a assail zone, memories that could be a saving grace or a dangerous self-destructive weapon. Women acquire a very special place for the men of OBriens plato on as they do for combat soldiers everywhere. The women they know and love, mothers, sisters, wives and girlfriends, are tens of thousands of miles remote. At times they are as mentally and emotionally distant as they are in geographic terms. When firefights rage the soldiers panoramas by necessity work fixed and focused on the chaos of combat surrounding them and the thought of women can be transitory or distracting. It may be a thought of the love one they hope to see if they survive, or the thought may distract them and cost them their life or the life of another(prenominal) soldier.Women are as real as their vivid dreams provided upon awakening on that point is the doubt they ever existed. The space they occupy is the anxious and unnerving demesne mixed with hope and doubt, happiness and depression. With their letters they provide a unify to the real world once occupied by the soldiers who may wonder if the women pass on be there for them if and when they return. The so ldier may hope their girlfriend will be there and doubt she will understand. The thought of the girlfriend may provide a solid foundation on which to live on another day, or with a dear John letter inadvertently provide a seemingly dim depression. The women occupy a space unlike any other space in the thoughts of the combat soldier. For deputy Jimmy Cross the thought of Martha, a junior at Mount Sebastian College in New island of Jersey was a constant preoccupation (1). She was a daily part of his life, and he had a riteistic idolatry to viewing photographs of her. She was in some(prenominal) ways the embodiment of the contradictions women occupied in soldiers thoughts. She was not quite a serious girlfriend and lover who was devoted to him and would be waiting for him. In fact their relationship earlier the war was one-sided And then suddenly, without willing it, he was thinking of Marthawhy so alone? non lonely, just aloneand it was her aloneness that filled him with love. H e remembered telling her that one evening. How she nodded and looked away. And how, later, when he flattered her, she received the kiss without returning it (11-12). Yet Cross would not let go of his attachment to her. He blamed it for the last of one of his soldiers now Ted Lavender was dead because he loved her so much and could not fall apart thinking about her (7). He felt that because of his preoccupation with her he failed to supervise his men and as a result Lavender was shot. As a result Cross decides to burn her photos and letters. Now he despised her. Yes, he did. He hated her. Love, too, but it was a threatening, hating kind of love (24). His feelings for her were just one of the many contradictions of the war. In some ways women became almost magical, and occupied the superstitious and surreal world of the thoughts and actions of men in combat. Henry Dobbins carried his girlfriends pantyhose wrapped around his neck as a comforter. They all carried ghosts (10). The s tockings gave Dobbins the memories that console him. Later he became convinced it truly was a good-luck charm as a boobytrap failed to detonate later on he tripped it and then survived a vicious firefight (117-118). For Dobbins and others the pantyhose gave access to a spiritual world and even by and by he receives a dear John letter he retains the pantyhose stating the magic doesnt go away (118). Other women, real or imagined came into the mens lives through their stories. The most dramatic stories are those that whirl prat and for the across the border between trivia and bedlam, the delirious and the mundane (89). OBrien recounts the stage of the dish antenna of the Song Tra Bong, the girlfriend of a soldier who manages to have her visit him at his medical-aid base (89-91).bloody shame Ann is but seventeen years old, but quickly adapts to the blood and gore of her clotheshorses line and becomes a valuable assistant treating the wounded. only if then she becomes more and more fixated to the war, the culture and the environment of Vietnam. She becomes pally with, and then a part of a contingent of the strange and isolated greenies, Special Forces soldiers stationed at the base. She in conclusion becomes a part of them. Soon she cannot be found despite her boyfriends search. According to the story she began going out with the Green Berets on combat missions. When she returned she was no longer what she had been.He had a hard time recognizing her. She wore a bush hat and filthy green fatigues she carried the standard M-16 automatic scandalize rifle her face was black with charcoal. Mary Ann handed (her boyfriend) the weapon. Im exhausted, she said. Well talk later. (102)Despite her boyfriends effort to get her away from the Green Berets and send her home she is hooked Vietnam had the effect of a powerful drug (114). Soon, the story goes, Mary Ann disappears into the jungle, never to be heard from again, only occasionally spy as a ghostly figure in the jungle. It is as though she served as a allegory for the space occupied by women in the war. They were far away in a land so remote it no longer seemed to exist. Then against all odds the soldier is able to literally minute the woman he loves. Then the war changes everything and destroys the relationship. For OBrien women in any case occupy a dual even so contradictory space in his life. His first unseasoned love is also his first collision with death. Although he and his girlfriend are only nine, OBrien know(s) for a fact that what we felt for each other was as deep and rich as love can ever get (228). Tragically she is suffering from a fatal disease and dies. For OBrien the memory of her, like his memory of fallen comrades, is and always will be sharp and vivid.For OBrien the lost friends and lost girlfriend are united in death and brought moxie to life in the memories and stories of those who survive. It is the vivid image of a casualty of the war that inexplicably re p romontorys him of his young girlfriend Linda all day long Id been picturing Lindas face, the way she smiled (228). For OBrien the dead will always be in a sense alive. The fallen troops and Linda are all dead. But in a story, which is kind of dreaming, the dead sometimes smile and sit up and return to the world (225). If OBriens lost girlfriend is a link to the departed his daughter Kathleen is the vision of life. He brings her to Vietnam when she is only ten, and seems to serve as the woman who will help him break his link to the deaths of Vietnam. She is too young to understand why her father has journeyed off the normal tourist sites to find the spot where a friend was killed and the body lost in the mire of a swampy river.She witnesses him as he performs a ritual burial of his late friends moccasins in the spot they found his body. It is though she is his tether back to reality, the present and life itself. Childlike she chastises him for his actions and cannot understand the im portance of the places she visits. She tells him he is weird for coming back to Vietnam, innocently proclaiming Like coming over here. Some dumb thing happens a long time past and you cant ever forget it (183). She presents the counterpoint of his life in Vietnam and it had to be an odd adept for OBrien to see his daughter in an area of Vietnam that is drastically different than the Vietnam of OBriens death. It brings up the idea and question of whether OBrien, in his wildest thoughts during his combat in that location that his daughter would stand in the same spot years later. Unlike the other women of memories and dreams Kathleen is able to be in Vietnam with him and help exclude that chapter of his life. As she notices a Vietnamese farmer staring at her father Kathleen asks if the old man is mad at her father. No, replies OBrien, All thats finished (188). For OBrien it seems as though he inevitably the female characters to make the connection between love and war and life and death. It is not always a successful link. His fellow soldier Norman Bowker had carried a picture of his girlfriend with him during his days and Vietnam but she had married. He saw her on his return, but while he could not bring himself to approach her and talk, he also could not pull himself from the memory and went past her house time and time (146). He later committed suicide. Women seemed to occupy the same space and provide the same ironic and contradictory thoughts as Vietnam itself. They were vital to the combat soldiers, but not present with them, or present as a mysterious Mary Ann. They could relegate a soldier a reason to stay alive or a reason to care less about living. They could be a distraction to take a soldiers mind off of the war or a distraction which could contribute to the horror of war. Like Martha they could be loved and hated at the same time. Like combat itself the women in the soldiers thoughts were both intensely private and yet communal.Works CitedOBri en, Tim. The Things They Carried. New York Broadway Books, 1990.

Abuse of power leads to conflict

We vibrate our business office like a club and the worldly concern bides its time until our Ignorance strips us of our glory. Stack Ab enforce of index refers to the unwarranted use of authority. A person or group of mass who abuse power, unjustifiably use their authority to exploit or harm those under their care or influence, or allow developing and perhaps harm to occur through lack of action. These powers can range in form, societal smirch, personal strength, knowledge, technology, weapons, wealth, or the trust that other(a)s have in them.It is evident from both history and in the current Edie, that deal in pop outs of power are often associated with misuse of their power. But does abuse of power lead to date? Or does action lead to abuse of power? One could say It goes both ways. The most drear abuse of power is sooner possibly neglect of children. The mother and or father are in a position where they should be giving their child or children everything they possibl y can, just now instead pack not to. They apportion only for themselves, and leave nothing for their offspring.Michelle Unguent was charged with murdering her Infant daughter, Thy, by going her In a car In outer Melbourne on a tot November day. It was said that she had repeatedly left the child in her car, sparking arguments with her hold mother regarding the level of care she was exerting for Thy. Michelle was in a place of power, she was responsible for the well- being of her offspring, but yet she abused her power, leading initially to conflict with her mother and ultimately, the stopping point of her little girl.Quite often we see ghostlike ministers misuse power for their own personal pleasure. In Australia on that point are over 100 cases where Catholic priests have been charged for ex offences against minors The misuse of social position, physical strength and trust have been used on numerous occasion for the religious leaders to sexually satisfy themselves. The victi mized children would feel uncomfortable and violated, if they were old enough to understand that It was wrong.Bishops and Cardinals abused their position to protect the priests, to save the churches Image. They simply moved the priests on to a new place of practice earlier than naming and shaming, allowing the exploitation to continue. At no point did any of the people in places in oarsman step forward to protect the children. No wiz wanted to prevent future conflicts by creating and rumpus at the time when minors most needed it. They abused their power to allow the abuse of other powers to continue, they encouraged the conflicts.TLS causes a conflict within the child as they grow up, they may question their own self worth and they could potentially become mentally and emotionally unable to function properly in a sexual relationship. Not only has the trust of the child been violated, the parents and guardians who willingly placed their loved one n their care have been let down a nd their trust, also, been broken. This particular abuse of power is one that creates come along conflict by limiting the heart and soul of trust people will put into churches and people of religious order, particularly those of Catholic denomination. rower to disadvantage someone else. Over the course of Sadisms 42 year reign, he kept his family placed in high national political standing. He gave his oldest son the job of neat a dominant face of telecommunications, while another son was the head of national security. Caitiff was a nepotism misusing his power to give advantage to his family, rather than those of the general public. In a sense, he disadvantaged the country by having a heavily weighted national political front to people who share his opinion.Everyday people use their power to exploit others for personal gain. We see it in many forms, but one that is quite distinct is human trafficking. Human trafficking is the trade in which humans are used sexually exploit or ar e used for forced labor ad sometimes for marriage. It is clearly an abuse of wealth, they take advantage of people in poverty. The victims simply cannot but their way out of it, especially if they are trafficked to even up of a debt. Human traffickers abuse the power of wealth. They create conflict with the law and the human race.They break the offhanded rules of humaneness, by seeing people simply as commodities and then denying them their basic human rights. Money is power. take for Harm is a clear example where power is abused. These people were not allocated their power, they stole it. They pressured their way into a negative place of rower through violence and the infilling of fear. They have explicitly stated they Will plow women. They have not only misused their power of wealth and weapons, he has greatly abused the summation of his illegally gained women.If this group of men are not pursued and made accountable, what message does it send to the world about the value of women if they get away with it? Not a very good one obviously, women in these countries are generally treated as objects, and breeders. They are often promised to older men at young ages and sometimes before birth. Most are unable o do anything of their own desire but rather only as their husband wishes, and if he is denied, he may do whatever he so chooses to punish her.The fact that a large number of young girls were taken without anyone speaking a word upon the occurrence of the crime simply supports the general ideals of this particular culture, women arent worth more than simply a sum of money. These men are allowing the rest of the world to look upon their actions and feel a certain amount of disgust, if they are not found and or punished, people internationally will start to worry, enduring where it is gum elastic to be anymore. Thus there is a conflict.Their abuse of the power of money, weapons and assets creates a conflict of security. Abuse of power and conflict go hand i n hand. Whether it be abuse of power causing conflict, or the conflict leading to the abuse of power. People misuse their power everyday. The power of trust, money, assets, weapons and the like. It happens in everyday life, and our history as a race is littered with it. We use our power to our advantage and we exploit others. Sometimes we turn a blind eye, using our power to cause the conflict.
