Access to Higher Education - Essay Example 33).Accessing the institutions of higher learning has however been a challenge even to the developed countries and this article tries to show why this is so and why in some countries it has been successfully implemented. This paragraph explores cost as a factor for access to higher education. One challenge that makes higher learning hard to achieve for everyone is the cost implication that comes with it. The cost of acquiring a degree is very high that not everyone in the society can be able to match. This poses a challenge to those in those in the lower class in the society (Harmon 2010, p. 75). Very often, you will find needy students that are very bright but cannot afford to further their studies. The only hope for these students is either to find a sponsor or the government loans and grants provided by governments especially in the developing world. To overcome such a challenge, countries like the Scandinavian countries have made tertiary education to be free for all its citizens regardless of their performance in the secondary school (Harmon 2010, p. 79). What this does is that it ensures no one is denied a chance to further his or her studies.Therefore, cost is really an issue. Next let us explore the loan factor in details.How is loan a factor? Loan as a helping factor to access to education involves the government offering to finance the education of its university population and recover the money once the student has graduated and found employment. The prohibitive factor in this case, however, is that not all students who complete their degrees do find jobs immediately or even at all and thus it is common to find a lot of defaulters and thus the government might not be able to offer enough funds to future deserving cases (White 2008, p. 19). What other governments do to avoid this is that they subsidize the cost of education for all students in public institutions of higher learning to a level where it is affordable to almost everyone. In Kenya for exa mple, the cost of degree courses in public universities there is averagely $300 a year. Such subsidies are however putting a strain in the overall running of the universities and most of them have been forced to look for funds from other sources to run the universities (Thomson 2009, p. 22). This brings in another element in the access to higher learning; inequality. How about exclusivity as a factor? Exclusivity definitely denies everyone access to the best tertiary institutions of choice but the good thing is for those who make it to these institution is the demand they will get in the job market. Here is a look at both sides of this discussion. There are some high end universities that are so sought after that they have to put extra requirement to be accessed. The so-called Ivy League Schools like Oxford and Yale are so expensive to the ordinary person that only the well-off do go there. While these universities actually deserve to be there, it is the inequality that exists that is the problem. You will find that there are different registration numbers for different student with one being for the self-sponsored and another for the government sponsored (Rubin 2012, p.35). This brings about favoritism as the self-sponsored tend to be more favored than the other students because of the amount of money that they bring in to the University. Graduates from these

Recommendation for Incentive Programms and Plans Essay
Recommendation for Incentive Programms and Plans - Essay Example It is imperative to go through some of these drawbacks to ensure that they do not get in the way of the companyââ¬â¢s development. One of the incentives introduced by a manager is that of having the employees receiving a promotion or a salary raise anytime that they produce results that appeal to the expectations of the manager (Muller, 2013). This is important in that most people get into the corporate arena with the aim of earning a lot of money for them to manage or rather improve their living styles. It is important to understand that this incentive has a drawback that revolves around it failing to have negativity. Negativity in this case is the employer does not impose any challenge to the employee if he or she fails to deliver appropriate jobs as expected. It is important to have this challenge as it makes the employee realize that there is a negative side to failure. One way through which to challenge this incentive is by ensuring that the employee is charged in the case of him or her failing to deliver appropriate work. One way through which to charge the employee is by having them deducted their commissions (Hartman, 2011). Commissioning is one of the ways through which employers motivate their employees as an incentive to have them work harder save from the monthly salary they receive. It is thus only fair to ensure that they are charged for poor performance by ensuring that part of their commission is actually deducted. Another incentive that employers have is buying or rather treating employees after they achieve certain goals. This is a very motivation appropriate plan as the employees get to work even more knowing that they will receive additional benefits. However, it is imperative to understand that increased working of the employees can create or rather creates the drawback of having them not providing quality work. In the contemporary environment, there is the issue of quality and quantity. The major drawback that

The Major Components Of Green Computing Information Technology Essay
The Major Components Of Green Computing Information Technology Essay As IT has become a major component in social infrastructure, it plays a vital role in humans life. Computing is a fast growing area which consumes energy a lot. A computer which performs well consumes lots of energy. It takes a lot of energy to create, package and retrieve data. With the development of the technologies, people tend to depend on these technologies more and more. It will lead us to many problems as energy is a non renewable resource. It will soon cost more to power a computer in future, than buying a new one today. Therefore we have to find methods, where we can minimize the wastage of energy while utilizing existing resources efficiently. Since computer plays a major role in our lives, demand for the energy, cost and wastage also increase dramatically. According to the Climate Saving Computing Initiative, the half of the power input to our PC is wasted without even reaching to the processor, memory, disk or any other component. Further, they have identified that added heat of the computer systems, inactive sleep and hibernate state of the computer and mal practices of using electronic equipments has a great impact in this energy wastage. It is estimated that out of $250 billion per year spent on powering computers worldwide only about 15% of that power is spent computing. The rest is wasted idling. Therefore, Green Computing is introduced in order to maximize the energy efficiency and increase the recyclability of products and the factory waste. Green Computing is focusing on creating technologies that help to preserve nature and minimize the bad effects of the technological development. Overview Green Computing is an echo friendly approach to the modern computing environment. It discusses about the ways of using computers in environmental friendly way. Ã The main focus of Green computing is reducing the environmental impact of industrial processes and innovative technologies caused by the Earths growing population and the ways of utilizing computer resources efficiently. It talks about serving social needs in a way which reduce the damage happen to the nature. Mainly this is talking about creating recyclable products, reducing pollution, providing alternatives to certain technological areas and etc. It is a concept which is already used in the IT environment. Researchers have found that most of the computers are not used for most of the time, but they are left running and many personal computers are left on unnecessarily. It leads to the high wastage of energy. These kinds of issues are also considered in Green Computing. It also talks about proper disposal of electronic w aste. Eco Friendly Computing Green Computing is also known as Green IT. Environmental sustainability, Energy efficiency, and the cost of disposal and recycling also includes in Green IT. History The Energy Star program commenced by the U.S. Environmental Protection Agency in 1992 was the first voluntary labelling program designed to promote and recognize energy efficiency. It is basically designed to promote and recognize energy efficiency in monitors, climate control equipments and other technologies. The term Green Computing immerged shortly after this Energy Star Program. The first function launched as a result of the Green Computing researches was the sleep mode function of computer monitor. Approaches to Green Computing In order to gain the environmental sustainability and efficient use of energy through computing there are four main paths to be taken. Green Use Using the computers and other related products in an efficient manner where the energy consumption is minimized. Green Disposal Reusing old computers, properly disposing and recycling other unwanted products. Green Design Designing energy efficient and environmentally friendly computers and accessories. Green Manufacturing Manufacturing computers and other related equipments in a way that they have a minimal effect to the environment. These four steps can be further spanned in to number of activities and areas. Efficient use of energy Power saving Server virtualization Environmental sustainable designing Responsible disposal and recycle Risk mitigation Use of renewable energy sources Eco- labelling Use of Green methodologies and assessment tools. As an initial step to the Green Computing the work habits of the individual computer users have to be changed. Most of the energy wastages regarding the personal computer usage happen because of the false beliefs regarding the computer usage. For an instance, people belief that when turning off a computer and turning on it back uses more energy than it leaving on. But the actual energy consumption of the computer when it boots up, is far less than the energy it uses when left on for more than three minutes. Further the use of notebook computers rather than using personal computers will also save energy. Moreover, people think that screen savers do save energy. But the fact is that they are designed to increase the lifetime of monochrome monitors. The screen savers will save energy if they actually turn off the screen or turn off the backlight of the laptops. By letting the users get to know about these facts will change their habits and it will lead to power utilization. When it comes to organizational level, many organizations have undertaken various kinds of activities as an approach to this Green IT. Telecommuting Virtualization VoIP Organizations have allowed their workers to work while being at home. This will help to reduce fuel emission at transportation. They are given all the necessary facilities to work. This is known as telecommuting. Virtualization refers to the consolidation of servers. It allows to two or more logical computer systems to run in one physical hardware. This leads minimum power consumption and maximum cooling. VoIP or Voice over Internet Protocol is a technology of voice transmission over internet or other packet switched networks. It reduces the telephone wiring infrastructure and is low cost. It is method of reducing metallic waste. Green business practices Green IT isnt just about energy efficiencies but also about operational efficiencies that can improve the organization. In most of the organizations, Green IT is practiced because of the explicit business drivers such as cost and the availability of the energy, cost of the equipments, cost of the data centres, business process optimization and performance and efficiency. When focusing on business optimization, few areas can be targeted which energy demand can be reduced and growth can be increased with the help of IT. Server and storage utilization and consolidation Server, storage, and application virtualization Technology and information life cycle strategies Energy measurement and management Green Information Strategy Under Green Information Strategy, the ways of managing and retaining information has been defined. The ways of collecting, classifying and archiving information are introduced in Green Information Strategy. It involves several key steps: Understanding the requirements for information retention and availability. Determining infrastructure requirements. Conducting continual strategic planning to meet economic and business conditions and demand. Measuring progress and adjusting the strategies. Information Lifecycle Management is a set of concepts which helps organizations to build processes and implement best practices for creating, storing, archiving, and dispose data. A variety of technologies and methodologies can be used in order to optimize the storage utilization. Then the amount of storage required and the energy used to power will be reduced. Maximizing data centre and server room efficiency Designing a data centre for maximum efficiency is complex and requires input from many disciplines not normally associated with IT. But most of the organizations dont have data centres. They have their IT equipments in a sever room. Server room is a data centre operated in a small scale. Here are few facts that have to be considered when designing a server room. Raised floor in computer rooms was the general accepted norm since vacuum tube era. Variable speed motors can tailor cooling power usage to need, producing substantial savings, and may prove less expensive in the long run though they are more expensive to purchase. The trend in servers is to pack more CPUs in to a single track. But when power densities get above 200 watts per square foot, because of the high heat generated, too much air is needed to remove the heat. Therefore racks (19-inch EIA-310-D standard) with built-in chillers or even water-cooled servers, become preferable. Use a large server. Replace physical servers with virtual servers. Blade servers Blade servers put each processor, memory and hard drive on one single card called blade. These blades are fixed in to a backplane. A single power supply, a shared cooling system, a shared network interface is used among the blades, which connected to a backplane. Replacing multiple servers with blade servers generally saves power and space. Green Storage Storage systems are among the systems which consume power and storage a lot. Drivers have to be full powered and running to be able to store data. Data Deduplication Data Deduplication is the term used for removing the duplicates. It examines the hard drive or the storage system and find out the duplicates and remove them. It effectively reduces the storage allocated for certain data file and allocates it to other additional data. It increases the capacity of your system. Thin Provisioning Thin provisioning is allocating right amount of storage is as needed. It helps to eliminate unused capacity. Storage can be used efficiently by allocating the required storage when it is needed and using storage management software to adjust it. As the storage is dynamically allocated the storage can be grown or shrink according to the application stored. Further storage management software can view applications simultaneously and allocate unused capacity as needed. Storage Virtualization Storage virtualization gets all the available capacity together from multiple storage systems and enables it to share, without requiring a change in storage hardware. By enabling sharing it avoids the trapped capacity, which is available but cannot be used by an application. Using Virtualization Multiple applications and multiple Operating systems can be run simultaneously with the use of virtual memory technology. Virtualization increases the utilization of computer systems by condensing applications into few servers. Therefore the number of required servers will be reduced. It reduced the power consumption of the data centres and the cooling requirements. Virtualization is one of the earliest paths to green, because when more than one application is run on a server (application consolidation) the number of servers required to support these applications is reduced. Fewer servers mean less power consumption and low energy requirement for cooling. Future Directions on Green Computing

The protagonists are the scientists: Norman, Ellen, Captain Barnes, Dr. Johnson, Beth, Harry, and Ted. The antagonist of the story at the beginning is a set of tragedies. Later the antagonist turns out to be themselves. The book starts out with the scientists having to take many vigorous mental and physical tests. Qualifying them to submerge themselves thousands of feet down into a spaceship of phenomenal dimensions. Many personality conflict arise. At one point communication is almost permanently lost with the surface world. An idea the spacecraft is from the future is shortly lived. Once the Sphere is opened, total anarchy takes control of the scientists lives. A monstrous squid, 15 times the size of a normally larger squid, emerges and destroys the living quarters of the scientists. Now they are forced to live in the spacecraft with all communication lost with the outside world. Killer shrimp, fire, and internal floods follow the introduction of the squid. Barnes is eaten alive by the gigantic squid. After the climax and many deaths the few people left discover whoever enters the Sphere is granted the power that everything they think or imagine happens or is created. Either it's conscious or subconscious, while they're sleeping or awake, or even if they really want it to happen. They also it was planted by another world as a test of its full capabilities and consequences. Ted actually imagines his own death, only to kill himself. Once their emergency submarine is lost, they realize they have a serious problem being trapped together.
Classifying Three NFL Teams According To Attitude :: essays research papers
Classifying Three NFL Teams According to Attitude The National Football League was formed decades ago by the merger of two national leagues. The Super Bowl is the traditional season-end activity that crowns the national champion. Each team represented starts with one of the original leagues.The number of teams active in the NFL does not remain the same for longr.o. the game of professional football is big business and can be highly profitable. When the NFL announces that it has approved new expansion teams, there is intense competition among team less cities to attract one of the franchises. The game is profitable for team owners and for players, but it also is profitable for the cities in which teams are centered. It contributes to the local economy and enhances the stature of the city in where a team is located. Of course teams and their organizations are made up of individuals, but the teams themselves tend to settle into characteristics of their own. Once established in reputation, the team can remain with it for years regardless of the changes that occur within and around it. Example can be seen in any NFL team. The Tampa Bay Buccaneers are technically sound playing but very bad results. The team has been winning with much greater frequency in recent years, but it can expect to maintain the loser perception for years to come. As teams take on their its own personality. Most of NFL teams relies rely on assessment of the number of games won compared to the number lost during a season or over a number of years. Teams also can be classified according to that personality, or at least according to the personality perceived by fans and the press. With the classification of good, average and bad. The Tennessee Titans will be used to show the good team the Minnesota Vikings will represent the average and the Dallas Cowboys will fill the role of bad. The Tennessee Titans The Titans provide a good example of how teams can change the perceptions that have built around them over the years. In the case of the Titans, the change was effected by moving to a new state, changing the team name, replacing personnel and replacing the coaching staff. The Titans hardly have the same team at all, but they formerly were the Houston Oilers. You should keep in mind that as the Oilers, the team had posted so many consecutive losing seasons that it had managed to destroy the reputation built during the winning years.

Electronic Voting Machine
International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 A Preview on Microcontroller Based Electronic Voting Machine Diponkar Paul and Sobuj Kumar Ray, Member, IACSIT Abstractââ¬âVoting is most pivotal process of democratic society through which people determine itââ¬â¢s government. Governments around the world are increasingly considering the replacement of traditional paper-based voting schemes with electronic voting systems.Elections of Bangladesh are conducted most exclusively using electronic voting machines developed over the past three years. In this paper we describe the design, construction and operation of a digital voting machine using a microcontroller profoundly. Again we also portray counting system of votes, market survey and cost analysis. Index Termsââ¬âVoting system, atmega16l microcontroller, voting analysis, security of EVM. I. INTRODUCTION Voting is a crucial device to reveal the opinion of a group on an issue that i s under consideration. Based on the promise of greater e? iency, better scalability, faster speed, lower cost, and more convenience, voting is currently shifting from manual paper-based processing to automate electronic-based processing. The term ââ¬Å"electronic votingâ⬠characteristically depicts to the use of some electronic means in voting and ensure the security, reliability, guarantee and transferency[1],[2]. Now a day the wide range of application of voting include its use in reality student body elections, shareholder meetings, and the passing of legislation in parliament. Perhaps the most important, in? ential, publicised, and widespread use of voting is its use in national elections. Compared to its traditional paper-based counterpart, electronic voting is considered to have many greater potential bene? ts. These bene? ts include better accuracy by eliminating the negative factor of human error, better coverage for remote locations, increased speed for tally computat ion, lower operational cost through automated means, and the convenience of voting from any location Whether or not electronic voting is a necessary replacement for the traditional paper-based method, it is irrefutable that the conduct of voting as been shifting to the use of electronic medium. To date, electronic databases are used to record voter information, computers are used to count the votes and produce voting results, mobile devices are used for voting in interactive television shows, and electronic voting machines have been used in some national elections. Generally, the term ââ¬Å"electronic votingâ⬠refers to the de? nition, collection, and dissemination of peopleââ¬â¢s opinions with the help of some machinery that is more or less computer supported. Despite Manuscript received August 15, 2012; revised October 12, 2012.The authors are with the Department Electrical and Electronic Engineering, World University of Bangladesh, Dhaka, Bangladesh (e-mail: [emailà pr otected] com, [emailà protected] edu. sg) the transition from traditional paper-based systems to electronic medium, the purpose and requirements for voting remain. Voting is a decision making mechanism in a consensus-based society and security is indeed an essential part of voting. The critical role in determining the outcome of an election, electronic voting systems should be designed and developed with the greatest care.However, a number of recent studies have shown that most of the electronic voting systems being used today are fatally defective [3], [4], [5] and that their quality does not match the importance of the task that they are supposed to carry out. Flaws in current voting systems, which were discovered through testing and other analysis techniques, have stimulated a number of research efforts to mitigate the problems in deployed voting systems. These efforts focused on ameliorating security primitives, such as the storage of votes [6], [7] and auditing [8], and on fo rmally assessing and making procedures more effective [9], [10].Finally, the standards that set the functional and performance requirements against which the systems are developed, tested, and operated have often been found to be inadequate [11], [12], [13]. Among the reasons for concern, critics include vague and incomplete security guidelines, insufficient documentation requirements, and inadequate descriptions of the configuration of commercial software. An electronic voting machine has been designed by a microcontroller for which the code is written in assembly language.Various code protection schemes specified by the manufacturer of the microcontroller are used to prevent inadvertent or deliberate reading and reproduction of the code contained in the microcontroller. The election data contained in the EEPROM of the microcontroller can download into a central computer for tabulations. The security of data in this computer is enforced by generating digital signatures for each dat a file created. This process makes it impossible for anyone to substitute wrong or deliberately altered data files at any intermediate stage between the capturing of voterââ¬â¢s intent by the machine and the final results tabulations.Prior to the election, all con? guration data is set up on the counting server. The con? guration is then transferred to the ballot-box server. Con? guration data include: candidate names, polling station identity, and a list of barcodes. During the voting period, voters are authenticated as per the traditional paper-based voting, and asked whether they wish to vote electronically or use the traditional paper-based method. A voter choosing to use the traditional paper-based method proceeds by being given a ballot paper, casting the vote on the ballot paper, and placing the ballot paper in a ballot-box.On the other hand, a barcode is chosen at random and is given to the voter choosing to use eVACS. Voter authorisation on the electronic voting booth co mputer is by 185 DOI: 10. 7763/IJIEE. 2013. V3. 295 International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 using the barcode. The electronic voting booth computer communicates the barcode to the ballot-box server for validation and to inform that the voting process is initiating. Upon validation of an invalid barcode, the ballot-box server returns an error message to the voting booth computer.Otherwise, the ballot-box server returns the equivalent of a ballot-paper containing the names of candidates to the voting booth computer. The voter may select the candidates in a particular preference ordering, and restart or complete their selection afterwards. The selection is displayed on the screen forcon? rmation, and the voter is allowed to change or con? rm their selection. The voting booth computer returns a warning given invalid selection or informal vote, however casting invalid or informal vote is allowed. The voter con? ms the selection by using the barcode, and both the vote and a log of key sequence pressed are then communicated to the ballot-box server. The ballot-box server checks that the same barcode is used to initiate the server counts the votes, and produces a voting result. II. HARDWARE DEVELOPMENT OF ELECTRONIC VOTING MACHINE Fig. 1. Block diagram of digital voting system Fig 2. Circuit diagram of the digital voting system A. Circuit Description The high level digital voting machine built with ATmega16 Micro controller. The Micro controller port D uses for LCD display and port C. (pin 22) uses for voting power or presiding officers button. The candided button input from Port C. 1 ââ¬â C. 4 (pin 23 to 26; 4 candided). The output LED and buzzer uses Micro controller port C. 5 and C. 6. The LCD backlight also connected to port C. 7 via a transistor. At the starting of voting the election commission offices setup the machine at the centre. Then power on the switch and sealed it that nobody can power off. The pre siding officer identifies the original voter of that particular area and pushes the voting power button. The voting power LED glow then and continue it until once press the candided buttons.The voter then goes to the secret room where Voting unit placed and press button beside his candided symbol. Voter can watch success of voting by glowing confirmation LED and beep indication. The presiding officer can also hear beep sound watch a confirmation LED. Same time the voting power goes down and nobody can vote again. Mainly when presiding officer press voting power button, Micro controller start scanning from pin 23 to pin 26. When get response from a specific pin, increase the counter one of that candided and stop scanning. So it is not possible to voting twice or more.All the counter result store at Micro controller EEPROM. When the voting is under process it will showed at display ââ¬Å"Voting under Processâ⬠. At the end of voting we need to know result. Then election commissio n or presiding officer presses the secret key (password). Now the Micro controller shows the result and supply the power to LCD backlight that it illuminated. If it needs to return voting process again one should press another secret key. There uses a transistor to operate buzzer and confirmation LED with proper current. There also uses a voltage regulator (7805) to supply 5v continuously.Here uses a dry cell 9V battery as power source. The power consumption of the system is very low (50mW150mW varying). After collected data and need erase recorded data from EEPROM just broken the sealed on power button and power off the system. Now the system is ready for next election. This measurement System includes the following components: â⬠¢ Voting Unit â⬠¢ Control Unit â⬠¢ Confirmation Unit â⬠¢ Display Unit (LCD) â⬠¢ Power Supply Unit B. Voting Unit Fig. 3. Output circuit diagram of the digital voting system Fig. 4. Voting 186 International Journal of Information and Ele ctronics Engineering, Vol. 3, No. 2, March 2013Fig. 5. Confirmation unit In this Voting unit we have been used five button switch and five 2. 2K? resister which connected to the five button switches. C. Buzzer A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical or piezoelectric. Typical uses of buzzers and beepers include alarm devices. These devices are output transducers converting electrical energy. As power is applied this mechanical device will energize and by doing so interrupt the power source and the cycle continue until the power is removed. The frequency of oscillation is strictly dependent on mechanical inertia.The piezo buzzer produces sound based on reverse of the piezoelectric effect. The generation of pressure variation or strain by the application of electric potential across a piezoelectric material is the underlying principle. These buzzers can be used alert a user of an event corresponding to a switching action, counter sign al or sensor input. They are also used in alarm circuits. The buzzer produces a same noisy sound irrespective of the voltage variation applied to it. It consists of piezo crystals between two conductors. When a potential is applied across these crystals, they push on one conductor and pull on the other.This, push and pull action, results in a sound wave. Most buzzers produce sound in the range of 2 to 4 kHz. The Red lead is connected to the Input and the Black lead is connected to Ground. D. Light Emitting Diode (LED) A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.When a light-emitting diode is forward-biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, 187 mproved robustness, smaller size, and faster switching. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output. Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (in particular brake lamps, turn signals, and indicators) as well as in traffic signals. LEDs have allowed new text, video displays, and sensors to be developed , while their high switching rates are also useful in advanced communications technology.Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances E. Controller Unit A control unit in general is a central part of the machinery that controls its operation, provided that a piece of machinery is complex and organized enough to contain any such unit. One domain in which the term is specifically used is the area of computer design. In this work Microcontroller ATMEGA 16L is used as the controller unit which controls the sensed signal.A single highly integrated chip that contains all the components comprising a controller. Typically this includes a CPU, RAM, some form of ROM, I/O ports, and timers. Unlike a general-purpose computer, which also includes all of these components, a microcontroller is designed for a very specific task ââ¬â to control a particular system. As a result, the parts can be simplified and reduced, which cuts down on production costs. Microcontrollers are sometimes called embedded microcontrollers, which just mean that they are part of an embedded system that is, one part of a larger device or system.F. Power Supply Unit Power supply is a very important part of electronic circuit this circuit required fixed +5 V supply so to fix this voltage we needed voltage regulator. In this work used 7805 Voltage regulator which output fixed +5 volt. A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. There are two types of voltage regulators: linear and switching. A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier.It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage. G. Display Unit Display device sho wn the result of the measuring instrument. A observer can see the result and observe the temperature of electrical machine. In this work we used a 2Ãâ"16 character LCD (LM016L) display. A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals. H. Printed Circuit Board A printed circuit board, or PCB, is used to mechanicallyInternational Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. It is also referred to as printed wiring board (PWB) or etched wiring board. A PCB populated with electronic components is a printed circuit assembly (PCA), also known as a printed circuit board assembly (PCBA). Printed circuit boards are used in virtually all but the implest commercially produced electronic devices. PCBs ar e inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire wrap or point-to-point construction, but are much cheaper and faster for high-volume production; the production and soldering of PCBs can be done by automated equipment. Much of the electronics industry's PCB design, assembly, and quality control needs are set by standards that are published by the IPC organization.

SOFTWARE DEVELOPMENT FOR ELECTRONIC VOTING MACHINE Flowchart of Program: user. In both of the systems that we analyzed, we found major security vulnerabilities that could compromise the confidentiality, integrity, and availability of the voting process. The results of our study suggest that there is a need for a drastic change in the way in which electronic systems are designed, deve loped, and tested.Researchers, practitioners, and policy makers need to define novel testing approaches that take into account the peculiar information flow of these systems, as well as the combination of computer security mechanisms and physical procedures necessary to provide a high level of assurance. Electronic voting software is not immune from security concerned. Here we describe Hack-a-vote, a simplified DRE voting system that we initially developed to demonstrate how easy it might be to insert a Trojan horse into a voting system.In case of a discrepancy, there either must be a row with the fresh random number. But without a mark of the voter or the alignment information on the ballot and on the receipt must differ. The proof consists either of a row containing the fresh random number but no mark without revealing which row this is or the proof consists of the two differing alignment bar codes without showing the mark at all. After the publication of the receipts the situatio n is analogous to the paper based schemes above as the voter possesses a correct receipt as electronic evidence.In addition to using unforgivable receipts with a special paper one can assume a trusted printer containing a chip card this printer could have the chip card and print the signature to the receipt. Having two in dependent ways to proved receipt to be not a forgery is a big advantage. REFERENCES D. Balzarotti, G. Banks, M. Cova, V. Felmetsger, R. A. Kemmerer, W. Robertson, F. Valeur, and G.

RESULTS AND ANALYSIS This work contributed to three very basic research questions arising: in the context of verifiable elections. First, we discussed the problem of keeping ballot secrecy to a certain extent in the case of a corrupted doting machine or voting authority. Our contribution to this is an approach where all secret information is encapsulated in the voting machine. Second, we considered the attack of receipt stealing and manipulation of the corresponding votes.Here we proposed a novel approach of linking all receipts by a hash chain such that each single receipt guards the integrity of all receipts issued previously. Together with a display in the polling place this approach shortens the time window in which an adversary can perform the ballot stealing attack without almost zero risk. Third, we discussed in detail the possibility of contesting an election based on the evidence provided by the verifiable election scheme. We compared the situation for Bingo Voting to the evidence provided by paper based schemes.We shortly sketched an approach to prove an error or a manipulation in the voting booth without vi olating ballot secrecy. However, this was only a proof of concept and for a practical application the usability of this approach needs to be further improved. V. CONCLUSION As part of these exercises, we devised a testing methodology, developed new tools that are specifically tailored to the security analysis of these systems, and learned a number of lessons, all of which should be of use to other 189 International Journal of Information and Electronics Engineering, Vol. 3, No. 2, March 2013 [12] M.

A ballot unit, which a voter uses to exercise his vote. And the other, a control unit used by the polling officials. But the EVM prepared by us is totally automated. MCU is acting as the Polling Officer in this EVM. Ballot Unit It consists of a 16Ãâ"2 LCD and IR LEDs. LCD displays the name of the post and candidate for which voting is going on IR LEDs are used as touch switches. For anything which you have to select, put your figure just above the option where it is being displayed on the LCD. Control UnitIt consists of a MCU and a 7 keys keypad. MCU stores the program, run it and also stores the data given by voters. We have made keypad, which can be used to input the name of Posts and the Candidates. By using this we will not have to program the machine each time before any election. One can enter the name of posts and candidates just before the election. This can also prevent programming the EVM t o favour any particular candidate. 1. 1 The Electronic Voting Mach ine ââ¬â An Electronic Marvel. Electronic Voting Machine (EVM) retains all the characteristics of voting by ballot papers, while making polling a lot more expedient.Being fast and absolutely reliable, the EVM saves considerable time, money and manpower. And, of course, helps maintain total voting secrecy without the use of ballot papers. The EVM is 100 per cent tamper proof. And, at the end of the polling, just press a button and there you have the results. 1. 2Description: Electronic voting machine has now days become an effective tool for voting. It ensures flawless voting and thus has become more widespread. It ensures people about their vote being secured. It avoids any kind of malpractice and invalid votes.Also such kind of system becomes more economical as consequent expenditure incurred on manpower is saved. It is also convenient on the part of voter, as he has to just press one key whichever belongsto his candidates. Voting machinesare the total combination ofmechanical,electromechanical, or electronic equipment (includingsoftware,firmware, and documentation required to program control, and supportequipment), that is used to define ballots; to cast and count votes; to report or display election results; and to maintain and produce any audit trail information.The first voting machines were mechanical but it is increasingly more common to use electronic voting machines. A voting system includes the practices and associated documentation used to identify system components and versions of such components; to test the system during its development and maintenance; to maintain records of system errors or defects; to determine specific changes made after initial certification; and to make available any materials to the voter (such as notices, instructions, forms, or paper ballots).Traditionally, a voting machine has been defined by the mechanism the system uses to cast votes and further ca tegorized by the location where the system tabulates the votes. Voting machines have different levels of usability, security,efficiency and accuracy. Certain systems may be more or less accessible to all voters, or not accessible to those voters with certain types of disabilities. They can also have an effect on the public's ability to oversee elections. SUMMARY Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security, automatic counting etc.This project presents a way to develop an electronic voting machine which displays the count of votes on a 16Ãâ"2 LCD interface. A user can get his/her vote register through a set of switches (one for each candidate). After every cast of vote, the subsequent count can be seen on LCD. The circuit uses AT89C51 microcontroller and the code for the project has been written in C. DESCRIPTION This LCD based electronic voting machine is designed for four candidates. The input part consists of a set of six tactile switches. The switches and 16Ãâ"2 LCD are interfaced to microcontroller AT89C51 for various operations and displays.The provision of casting votes for the candidates has been provided through four of these switches. These switches are made active high and connected to pins 2-5 (P1^1 ââ¬â P1^4) of the controller. The remaining two switches (both active low) are to start and stop the voting procedure. They are connected to pins 1 and 6 (P1^0 and P1^5) respectively. The Init (start) switch initializes the voting system when pressed, while the Stop switch ends the voting and displays the poll results on LCD screen. For more details on working with LCD, refer LCD interfacing with 8051.The data pins of the LCD (pins 7-14) are connected to the output port P2 of the microcontroller. The control pins (RS, R/W and EN) are connected to port P3 pins P3^0, P3^1 ; P3^6 respectively. Working: The voting is started by pressing the Init switch after which the user is p rompted to vote. The count of votes is stored in four different variables. As soon as the user votes for a candidate by pressing one of the switches, the value of the corresponding variable is increased by one. After this a Thank you message is displayed on LCD to acknowledge the registration of userââ¬â¢s vote.The message stays on the screen until the next user either presses the Init button to cast another vote or Stop switch is pressed get the poll results. When the stop button is pressed, the names of the candidates are displayed along with their vote counts. After some delay, the result is displayed which could be either declaration of the winner candidate or the candidates with a clash of their number of votes. PRESET | | A preset is a three legged electronic component which can be made to offer varying resistance in a circuit.The resistance is varied by adjusting the rotary control over it. The adjustment can be done by using a small screw driver or a similar tool. The res istance does not vary linearly but rather varies in exponential or logarithmic manner. Such variable resistors are commonly used for adjusting sensitivity along with a sensor. The variable resistance is obtained across the single terminal at front and one of the two other terminals. The two legs at back offer fixed resistance which is divided by the front leg. So whenever only the back terminals are used, a preset acts as a fixed resistor.Presets are specified by their fixed value resistance. | | AT89C51 MCAT89C51 is an 8-bit microcontroller and belongs to Atmel's 8051 family. ATMEL 89C51 has 4KB of Flash programmable and erasable read only memory (PEROM) and 128 bytes of RAM. It can be erased and program to a maximum of 1000 times. In 40 pin AT89C51, there are four ports designated as P1, P2, P3 and P0. All these ports are 8-bit bi-directional ports, i. e. , they can be used as both input and output ports. Except P0 which needs external pull-ups, rest of the ports have internal pul l-ups.When 1s are written to these port pins, they are pulled high by the internal pull-ups and can be used as inputs. These ports are also bit addressable and so their bits can also be accessed individually. Port P0 and P2 are also used to provide low byte and high byte addresses, respectively, when connected to an external memory. Port 3 has multiplexed pins for special functions like serial communication, hardware interrupts, timer inputs and read/write operation from external memory. AT89C51 has an inbuilt UART for serial communication.It can be programmed to operate at different baud rates. Including two timers & hardware interrupts, it has a total of six interrupts.

A 16Ãâ"2 LCD display is very basic module and is very commonly used in various devices and circuits. These modules are preferred over seven segments and other multi segment LEDs. The reasons being: LCDs are economical; easily programmable; have no limitation of displaying special & even custom characters (unlike in seven segments), animations and so on. A 16Ãâ"2 LCD means it can display 16 characters per line and there are 2 such lines.In this LCD each character is displayed in 5Ãâ"7 pixel matrix. This LCD has two registers, namely, Command an d Data. The command register stores the command instructions given to the LCD. A command is an instruction given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position, controlling display etc. The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD.

It could also be used to conduct opinion polls during annual share holders meeting. It could also be used to conduct general assembly elections where number of candidates are less than or equal to eight in the current situation. It could be used at places where there is no electricity as the thing is operational with the help of a simple 5 volt battery.It could well become a fine example of using environment friendly resources as there is no need for having lakhs of ballot papers as was used in older system of voting. It involves very less time for a voter to actually cast its vote unlike conventional method where it becomes very cumbersome to handle ballot papers. It is more fast and reliable. FUTURE SCOPE Number of candidates could be increased by using ot her microcontroller or an 8255 IC. It could be interfaced with printer to get the hard copy of the result almost instantly from the machine itself.It could also be interfaced with the personal computer and result could be stored in the central server and its backup could be taken on the other backend servers. Again, once the result is on the server it could be relayed on the network to various offices of the election conducting authority. Thus our project could make the result available any corner of the world in a matter of seconds In days of using nonpolluting and environment friendly resources of energy,it could pose a very good example.REFRENCES AND BIBLOGRAPHY 1.
