ABSTRACT The importance of sales accounting is gradually being recognized as germane to prudent management of any business firm. This has necessitated the need for the computerization of structured operations as the sales managers structured operations are known with certainly for instance, the computation and decisions based on sales ratios. This project therefore is a case study of Presidential Hotel. It describes the computerization of the sales accounting of the hotel as packaged for...
ABSTRACT The multimedia application user can use sound right off the bat on both the Macintosh and on a multimedia PC running Windows because beeps and warning sounds are available as soon as the operating system is installed. On the Macintosh you can choose one of the several sounds for the system alert. In Windows system sounds are WAV files and they reside in the windowsMedia subdirectory. Sound is perhaps the most important element of multimedia. It is meaningful “speech” in any lang...
ABSTRACTAnti-phishing strategy uses visual characteristics to identify potential phishing sites and measure suspicious pages similarity to actual sites registered with the system. The first of two sequential processes in the SiteWatcher system runs on local email servers and monitors emails for keywords and suspicious URLs. The second process then compares the potential phishing pages against actual pages and assesses visual similarities between them in terms of key regions, page layouts, and...
ABSTRACTVirtual Queue-based marking schemes have been recently proposed for AQM (Active Queue Management) in Internet routers. We consider a particular scheme, which we call the Adaptive Virtual Queue (AVQ), and study its following properties: stability in the presence of feedback delays, its ability to maintain small queue lengths and its robustness in the presence of extremely short flows (the so-called web mice). Using a linearized model of the system dynamics, we present a simple rule to ...
ABSTRACTStreaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a streaming provider. The name refers to the delivery method of the medium rather than to the medium itself. The distinction is usually applied to media that are distributed over telecommunications networks, as most other delivery systems are either inherently streaming (e.g., radio, television) or inherently non-streaming (e.g., books, video cassettes, audio CDs). The ve...
ABSTRACT This Working Group Note presents measurement results of various high-performance XML interchange encoding formats and their associated processors, made by the Efficient XML Interchange (EXI) Working Group. The measurements have been conducted following the recommendations of the XML Binary Characterization (XBC) Working Group. In particular, this draft covers measurements of the properties of "compactness", "processing efficiency" and "roundtrip support", as defined by the XBC ...
ABSTRACT The term virtual library is diffuse enough to be applied to a wide range of collections and organizations, but to be considered a virtual library, a virtual collection of information must be managed by and made accessible to a community of users. Thus, some web sites can be considered virtual libraries, but far from all. Many of the best known virtual libraries are older than the web including Project Perseus, Project Gutenberg, and ibiblio. Nevertheless, as a result of the developm...
ABSTRACT This project work is an attempt to control the speedof the vehicle designed with computer software to enable thethird party or owner to get the location, speed and activity of thedriver. To achieve this, the system can transmit the informationin real time. The use of GSM/GPRS technologies allows thesystem to track the objects and provide the up-to-dateinformation. This information is authorized to specific users over the internet as the server gets the information. It is the tele-moi...
ABSTRACT In today’s world where the Internet has experienced tremendous growth, social networking sites have become highly significant in students' lives. The aim of the study was to analyze the impact of social media on students. To achieve this, the survey research method was used. Three research questions guided the study. Research findings showed that a great number of students had access to the internet. Survey technique, interview, and online observation were the research methods used...
ABSTRACTActive networking is the emerging technology that will provide new network environment where lots of potential applications can be enhanced and developed. Current IP network is somehow good at simple packet forwarding, but it desperately needs some flexibility to support QoS and has to meets some restraint in certain environment. Active packets allow many functionalities with great flexibility, however way too slow for data forwarding. To realize best performance in wireless environme...
ABSTRACTOptimization is the process of transforming a piece of code to make more efficient (either in terms of time or space) without changing its output or side-effects. The only difference visible to the code’s user should be that it runs faster and/or consumes less memory. It is really a misnomer that the name implies you are finding an "optimal" solution— in truth, optimization aims to improve, not perfect, the result. Optimization is the field where most compiler research is done...
ABSTRACTWireless ad hoc networks are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach that addresses simultaneously three aspects: security, scalability and adaptability to changing network conditions. Our communication protocol, Castor, occupies a unique point in the design space: It does not use any control messages except...
ABSTRACTMulticast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy, multiple paths and multicast tree structure. Tree graph optimization problems (GOP) are usually difficult and time consuming NP-hard o...
ABSTRACTMeasurement and estimation of packet loss characteristics are challenging due to the relatively rare occurrence and typically short duration of packet loss episodes. While active probe tools are commonly used to measure packet loss on end-to-end paths, there has been little analysis of the accuracy of these tools or their impact on the network. The objective of our study is to understand how to measure packet loss episodes accurately with end-to-end probes. We begin by testing the cap...
ABSTRACT Technological trend in recent time’s nit nesses an appreciable decrease in hardware cost, implementation in microchip technology and a boost in the use of micro – computer’s in all ere as of human life. Transcutaneous electrical nerve stimulation unit (acronym TENS unit) is the use of electric current produced by a device to stimulate the nerves for therapeutic purposes. TENS by definition covers the complete range of transcutaneously applied currents used for nerve excitatio...
