ABSTRACT In the higher institution, it is the duty of the management to provide the students with conducive environment for learning. In a country like Nigeria, the number of students in higher institutions is quite massive. In a situation like this, the management of the some of these higher institutions may be tempted to admit more students than can manage. This may put the welfare of the students of risk. Over the years, the students’ welfare/affairs departments of most schools in N...
ABSTRACT A high-level programming language developed by Sun Microsystems. Java was originally called OAK, and was designed for handheld devices and set-top boxes. Oak was unsuccessful so in 1995 Sun changed the name to Java and modified the language to take advantage of the burgeoning World Wide Web. Java is an object-oriented language similar to C++, but simplified to eliminate language features that cause common programming errors. Java source code files (files with a .java extension) are...
ABSTRACT Debugging is a necessary process in almost any new software or hardware development process, whether a commercial product or an enterprise or personal application program. For complex products, debugging is done as the result of the unit test for the smallest unit of a system, again at component test when parts are brought together, again at system test when the product is used with other existing products, and again during customer beta test, when users try the product out in a real...
ABSTRACT Interest is a fee paid by a borrower of assets to the owner as a form of compensation for the use of the assets. It is most commonly the price paid for the use of borrowed money, or money earned by deposited funds. When money is borrowed, interest is typically paid to the lender as a percentage of the principal, the amount owed to the lender. The percentage of the principal that is paid as a fee over a certain period of time (typically one month or year) is called the interest rate...
ABSTRACT This paper will discuss the need for computer forensics to be practiced in an effective and legal way, outline basic technical issues, and point to references for further reading. It promotes the idea that the competent practice of computer forensics and awareness of applicable laws is essential for today’s networked organizations. This subject is important for managers who need to understand how computer forensics fits as a strategic element in overall organizational computer...
ABSTRACT The United Nations has designated 1981 the International Year for Disabled Persons. It is therefore appropriate that Computer is dedicating its first issue of the year to computing and the handicapped. The evolution of low cost computing technology promises an unprecedented spectrum of opportunities for the developmentally disabled. From aids to independent living to flexible tools that can greatly increase the variety and quality of job opportunities, the rapidly evolving field of c...
ABSTRACT Cryptography is an emerging technology in which two parties can secure network communications by applying the phenomena of quantum physics. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. Quantum cryptography was born in the early seventies when Steven Wiesner wrote "Conjugate Coding", which took more than ten years to end this paper. The quantum cryptography relies on two important elements of quantum mechanics - the Heisenberg Unc...
ABSTRACT Power system stabilizers (PSS) must be capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbance. Traditional PSS rely on robust linear design method in an attempt to cover a wider range of operating condition. Expert or rule-based controllers have also been proposed. Recently fuzzy logic (FL) as a novel robust control design method has shown promising results. The emphasis in fuzzy control design center is around uncertainties...
ABSTRACT Various proposals, including improved analog connectors, hybrid digital-plus-analog approaches, and several all-digital interfaces have been put forth since the early 1990s. One, the Digital Visual Interface (DVI), which is available in analog plus digital and digital-only forms, has seen reasonable success in higher-end PC products, but has not managed to take the majority of the market from the VGA. Concerns over image quality, the near-complete replacement of the CRT by LCDs and ...
ABSTRACT A transaction processing system is a type of information system. TPSs collect, store, modify, and retrieve the transactions of an organization. A transaction is an event that generates or modifies data that is eventually stored in an information system. To be considered a transaction processing system the computer must pass the ACID test. The essence of a transaction program is that it manages data that must be left in a consistent state, e.g. if an electronic payment is made, the am...
ABSTRACT If warnings can be provided efficiently and reliably as input to private dissemination systems, and if the public perceives a value and desire to receive these warnings, then private enterprise has a clear mandate to justify the development of new distribution systems or modification of existing systems. The technology exists not only to add such a feature, but to have the local receiver personalize the warnings to say, for example, “Tornado two miles southwest of you. Take co...
ABSTRACT Secure electronic payment system is presented in this paper. This electronic payment system is to be secure for clients such as customers and shop owners. The security architecture of the system is designed by RC5 encryption / decryption algorithm. This eliminates the fraud that occurs today with stolen credit card numbers. The symmetric key cryptosystem RC5 can protect conventional transaction data such as account numbers, amount and other information. This process can be done elect...
ABSTRACT This work entitled “Employee Management System†has been designed towards improving the Management of Employee Information in the field offices of acompany. It maintains Seniority, Leave Records, Transfer & Postings and other basic information of Employee. Various MIS reports can be generated through it Viz. Ever since man discovered the computer, attempt has been made to computerize every facet of human life. This work expresses the issue of designing and implementing an E...
ABSTRACT The distance over which data moves within a computer may vary from a few thousandths of an inch, as is the case within a single IC chip, to as much as several feet along the backplane of the main circuit board. Over such small distances, digital data may be transmitted as direct, two-level electrical signals over simple copper conductors. Except for the fastest computers, circuit designers are not very concerned about the shape of the conductor or the analog characteristics of signa...
ABSTRACT Recently face recognition is attracting much attention in the society of network multimedia information access. Areas such as network security, content indexing and retrieval, and video compression benefits from face recognition technology because "people" are the center of attention in a lot of video. Network access control via face recognition not only makes hackers virtually impossible to steal one's "password", but also increases the user-friendliness in human-computer interacti...
