of multimedia technology, the traditional information retrieval techniques do not meet the users demand. Recently, the content-based image retrieval has become the hot topic and the techniques of content-based image retrieval have been achieved great development. In this paper, the basic components of content-based image retrieval system are introduced. Image retrieval methods based on color, texture, shape and semantic image are discussed, analyzed and comparedMining association rules in...
Introduction Data mining is concerned with discovering new, meaningful information, so that decision makers can learn as much as they can from their priceless data assets. Via advanced information technologies, knowledge discovery in databases (KDD) can uncover veins of surprising and fair insights in a mountain of factual data. Data warehousing is a methodology that unites and synchronizes many sets of diversified data into a unified and reliable body of useful information. In larger...
A new secure route discovery protocol is proposed for MANETs that overcomes the vulnerabilities due to hidden channel attacks. It uses authentic neighbourhood for route discovery process which potentially protects hidden channels of routing packets, besides ensuring authenticity and integrity of routing messages at hop-by-hop level. This authentic neighbourhood is augmented by a process of traceability which uses promiscuous mode of a node to detect, diagnose and isolate the adversarial nodes...
This project comprises two portions. The first portion required the students to choose three encryption methods and conduct thorough research on it. The second portion is the development of a simple encryption and decryption program that reads in text message over a network.2.0 IntroductionThe three encryption methods chose was Data Encryption Standard (DES), Triple Data Encryption Standard (3DES), and Advance Encryption Standard (AES). In-depth investigation and study were done according to...
The ad hoc demand distance vector (AODV Protocol) routing algorithm is a routing protocol for mobile ad hoc network design. AODV protocol is able to unicast and multicast routing. It is an on-demand algorithm, meaning that it creates between nodes, routing node as the only source of hope. It maintains these routes as long as the resources they need.In addition, trees form of AODV protocol to connect multicast group members. These trees are members of the team members and the nodes need to be...
Abstract- In this paper we propose a novel method for establishing reliable and efficient data transmission in wireless sensor networks. By this approach we first attain energy efficiency by using hierarchical clustering method to form clusters in the sensor network. Network lifetime is increased on using this technique. To attain reliability and to utilize energy much more effectively multiple mobile sinks are used along with base station. Mobile sink nodes are used to enhance the performance...
A web application is an application that is hosted in browser-controlled environment over a network such as the internet or intranet. they consist of static web pages or they can be more advanced and consist of JSP files, Java servlets other web resources that include image files, compressed archives. Web applications are deployed within a web server, such as Resin. Each web application has a corresponding URL. URL has a unique name or path that identifies it within the server. The URL begins...
Micro/nano positioning technique is one that is the key enabling methodologies in engineering and science applications and it performs a crucial role in modern technologies such as scanning tunnel microscopy, X ray lithography, bio medicine, micro/nano surgery and surface metrology, etc. The motion resolution and positioning accuracy in the scientific and engineering fields generally requires within the range of several to a few hundreds of nanometers. Moreover, another potential requirement...

Apple Inc. introduced the iPhone to the public in 2007 and since then its popularity is ever growing. There are now more than 400 million accounts with registered credit cards in the App Store, making it the store with the most credit cards on file anywhere in the world. There are approximately 650,000 apps in the App Store, 225,000 of which are for iPad. Thirty billion apps have been downloaded in total. Apple has paid developers $5 billion in checks (meaning Apple has pocked about $2.5...
