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 The effect of pesticides, chchlorodipheny trichloroethane (DDY) and Benzene hexaxhoride (BHc) on the microflora of the three types of soil (loamy, clay and sandy soil) was conducted. The serial dietitian technique was employed up to 10-3 using nutrient agar, potato dextrose agar and sabourand agar plates. The isolation of both bacterial and fungal organisms were made before treating the soil types with the two pesticides), D.D.T and BHC. and after treating the soil types with ...
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...
ABSTRACT Today’s crucial information networks are vulnerable to fast-moving attacks by Internet worms and computer viruses. These attacks have the potential to cripple the Internet and compromise the integrity of the data on the end-user machines. Without new types of protection, the Internet remains susceptible to the assault of increasingly aggressive attacks. A platform has been implemented that actively detects and blocks worms and viruses at multi-Gigabit/second rates. It uses the...
ABSTRACT Determining the type of database to be deployed for a project is a combination of access requirements and preference. In an effort to make an informed decision on which to deploy, the application engineer should be familiar with the types of databases as well as the pros/cons of each. In this entry we will consider two general types of databases and explore some of their applications and key points in the decision cycle when faced with a project. A "flat file" database allows the use...
ABSTRACT The on-line voting system ensures that each intended voter is checked whether he/she is registered or not, if he/she is not registered, the system refuses him voting. Also it checks whether he/she has voted for that particular election. This on-line voting system prevents a situation where a particular candidate seizes the voters’ cards, and uses them to vote for himself. Hence the rigging associated with the manual voting systems has been completely handled. The syste...
ABSTRACT Cloud technology provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallels to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service. Cloud technology describes a new supplement, consumption, and delivery model for...
ABSTRACT In electrical engineering and computer science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or, a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. Image processing usually refers to digital image proces...
ABSTRACT Neural networks have emerged as a field of study within AI and engineering via the collaborative efforts of engineers, physicists, mathematicians, computer scientists, and neuroscientists. Although the strands of research are many, there is a basic underlying focus on pattern recognition and pattern generation, embedded within an overall focus on network architectures. Many neural network methods can be viewed as generalizations of classical pattern-oriented techniques in statistics...
ABSTRACT An extranet extends an intranet by providing various levels of accessibility to authorized members of the public. For example, a corporation may extend their intranet to provide access to specific information, such as their ordering system, to registered customers. The largest and most widely accessed network is the Internet, a worldwide network of computers that is not controlled by any one organization. An intranet is a network that is used by a single organization, such as a corpo...
