ABSTRACT Instant messaging systems allow users to exchange files. Current systems transfer files directly between peers rather than through the server, as with text messaging. In other words, the peer-to-peer scheme is used to eliminate the high bandwidth demands that server-centric file transfers would place on the provider’s network. Currently, none of the major instant messaging systems encrypt files transferred between instant messaging clients. While the files do not directly flow thro...
ABSTRACT Imaging System is a collection of hardware and software that work together to capture, store and retrieve images. A sample system includes a scanner, management. This study investigate computer Imaging System in Nigeria Hospital. Ordinary, some doctors use trial and error method in treating patients. As a result, wrong drugs can be prescribed. Also, the manual process of treating internal sickness waste a lot of time and affects the accuracy, effectiveness and competence of the organ...
ABSTRACT A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This paper suggests an approach to utilize location information (for instance, obtained using the global positioning system) to improve performance of routing protocols for ad hoc networks. By using location information, the proposed...
ABSTRACT We implemented a distributed, peer-to-peer file system in Java using the Chord protocol for efficient location of files stored across a network. Chord is a distributed key lookup technique that scales logarithmically with an increase in the number of storage nodes. Initially, we discovered problems with the Chord algorithms, and prototyped corrections to verify the changes. To implement the file sharing system, a Sockets-based messaging framework was implemented in Java, using comman...
ABSTRACT Images account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, but this is overly restrictive for image data. Our analysis shows that the in-order delivery abstraction provided by a TCP-based approach prevents the receiver application from processing and rendering portions of an image when they actually arrive. Thus an image is rendered in bursts interspersed with long idle times rather than smoothly. This paper descr...
ABSTRACT Inventory Management System is important to ensure quality control in businesses that handle transactions revolving around consumer goods. Without proper inventory control, a large retail store may run out of stock on an important item. A good Inventory Management System will alert the retailer when it is time to reorder. Inventory Management System is also an important means of automatically tracking large shipments. For example, if a business orders ten pairs of socks for retail re...
ABSTRACT As the recent denial-of-service attacks on several major Internet sites have shown us, no open computer network is immune from intrusions. The wireless ad-hoc network is particularly vulnerable due to its features of open medium, dynamic changing topology, cooperative algorithms, lack of centralized monitoring and management point, and lack of a clear line of defense. Many of the intrusion detection techniques developed on a fixed wired network are not applicable in this new environm...

ABSTRACT Integrated speech engine (ISE) technology on a computer refers to the combination of text appearing on the computer display together with the computer speaking that text aloud with a digitized or synthesized voice. Digitized speech is a recorded (or digitized) human voice speaking, and synthesized voice is a computer-generated voice speaking the text. This project focuses on ISE software tools that use synthesized speech to read any text. There are a wide range of ISE software tools ...
ABSTRACT IP multicast is facing a slow take-off although it has been a hotly debated topic for more than a decade. Many reasons are responsible for this status. Hence, the Internet is likely to be organized with both unicast and multicast enabled networks. Thus, it is of utmost importance to design protocols that allow the progressive deployment of the multicast service by supporting unicast clouds. This paper presents HBH (hop-by-hop multicast routing protocol). HBH adopts the source-specifi...
ABSTRACT Images account for a significant and growing fraction of Web downloads. The traditional approach to transporting images uses TCP, which provides a generic reliable in-order byte-stream abstraction, but which is overly restrictive for image data. We analyze the progression of image quality at the receiver with time, and show that the in-order delivery abstraction provided by a TCP-based approach prevents the receiver application from processing and rendering portions of an image when ...
ABSTRACT In this paper, we propose a volume rendering method using grid computing for large-scale volume image. Grid computing is attractive because medical institutions and research facilities often have a large number of idle computers. A large-scale volume image is divided into sub-volumes and the sub-volumes are rendered using grid computing. When using grid computing, different computers rarely have the same processor speeds. Thus the return order of results rarely matches the sending or...
ABSTRACT A HTML editor is an authoring software program that is used to create content for web sites. HTML software is easy to use since it has a feature that is known as WYSIWYG. When you design web pages you want to use editor features that are simple to understand. You can buy and download HTML management software from the Internet as well as templates that will help you create web pages for your business or personal use. There are many advantages to you when you use editing software to de...
ABSTRACT Text encryption software to hide and encrypt data within a picture undetectable to others! This software allows you to hide text messages within a picture! You can use this software to store personal information, financial details and so forth embedded within a picture, and password protect! So you could even give someone a copy of your videos and they would never know it had your personal information on it! Or, if you want more privacy when sending e-mails, encrypt a message in a pi...
