Abstract- We are in an era where the technologies that enable people to easily capture and share digitized video data are rapidly developing and becoming universally available. To date, handheld devices and the Internet have become a common method to create and transport video documents. As a result, there has been a huge increase in the utilization of videos and images as one of the most preferred types of media due to its content richness for many significant applications. The ubiquities of...

Before we began with defining Operations masters, we will have to get an understanding of what Active Directory is. Active Directory is nothing but a database enabled for multimaster use, and provides the flexibility of making directory changes at any domain controller. For this to happen, we assign one domain controller, known as the Operation Master, to accept request for change. Only the domain controller holding Operation master role is allowed to process the updates to the directory. In an...

Optimization can be defined as a method of maximizing or minimizing a function of various variables i.e. finding the values of the variables for which the function takes on the minimum or maximum value. The function f(x), called the merit function or objective function, is the quantity that one wishes to keep as small as possible, such as cost, or wishes to keep as large as possible, such as net present worth (NPV). The components of x, known as design variables or decision variables, are the...

Abstract- With the growing popularity of wireless mobile ad hoc networks(MANETs), many security concerns have arisen from MANETs especially the misbehaving nodes pose a major threat. Node misbehaviour in ad hoc network is caused by lack of cooperation and goes under the name node selfishness. A selfish node does not directly intent to damage other nodes with active attacks but it simply does not cooperate in network operation, saving battery life for its own communication. The problem of...

Today, many people rely on computers to do homework, work, and create or store useful information. Therefore, it is important for the information on the computer to be stored and kept properly. It is also extremely important for people on computers to protect their computer from data loss, misuse, and abuse. For example, it is crucial for businesses to keep information they have secure so that hackers can't access the information. Home users also need to take means to make sure that their...

Many computer related vision technology, it is critical to identify moving objects from a sequence of videos frames. In order to achieve this, background subtraction is applied which mainly identifies moving objects from each portion of video frames. Background subtraction or segmentation is a widely used technique in video surveillance, target recognitions and banks. By using the Gaussian Mixture Model background model, frame pixels are deleted from the required video to achieve the desired...

Web-Mapping can be defined as a process by which maps are designed, implemented, generated and delivered on the World Wide Web. The World Wide Web started in the mid 90's and then changed the way maps were being created, published and used (Kraak, 2001).it has since be used to publish maps on the World Wide, (Cartwright, 1999). In this present day, millions of map is now being accessed through the web, (Peterson, 2003). In 2001, Kraak made the first classification of Web Maps. He classified...

Recently a new type of database - NoSQL - has got significant amount of attention from big internet companies. The so called Non-relational databases have become very popular. They provide high availability and scalability for both read and writes. In these NoSQL databases caching and consistency are the two main concerns. This article will provide information about Cluster layer caching and data consistency using Plaxo. This article explains how node split technique in conjunction with...

Abstract In common practice, several estimation methods for software reliability models often depend on assumptions such as statistical distributions which are often unreliable in most of the cases. In this Paper we proposed a simple framework for Software Reliability Models in which we indicated a Parameter Estimation Method by using conventional Ant Colony Optimization and the Enhanced Simulated Ant Colony Optimization with real failure data and shown numerically with proposed parameter...
