ANN is a computational model which developed on the basis of structural and functional aspects of biological neural networks. It is formed by an interconnected group of artificial neurons. This system is an adaptive system which changes according to the information flow through it. This is known as learning process. During the training process, the network of neurons will increase in size and also the number of artificial neurons will also get increased (Artificial neural networks, 2009). Thus...
In a receiver system, it is necessary that the frequency of the incoming RF signal be down converted to a lower value. Since nonlinearity is fundamentally necessary to generate new frequencies, down conversion is achieved using a non linear circuit. Mixer circuit has non linear transfer function and thus used for frequency translation. Both up converted and down converted signals can be generated using mixers. In a receiver, this conversion is from Radio frequency to intermediate frequency. The...
This chapter focuses about a literature review of the recent application designed by the previous researches. A discussion covers previous similar system developed. Besides that, studied have been carried out on encryption and decryption, hashing process and many more related that associates with this project. This paper has presented a novel biometric key binding method, enhanced BioHash. Meng Ao and Stan Z. Li introduced the BioHash method and describe the NIR face based encryption...
Star Carr is considered to be an important site for understanding the Mesolithic period. Consider why this situation exists and outline what factors limit the available evidence for hunter- gathers in Britain during this period. To understand Star Carr, we most place the site in context with the larger Mesolithic landscape of Britain. Is Star Carr important and if so why? What evidence does Star Carr show us of Mesolithic hunter gathers, and what does this evidence suggest. Along with these...
In todays competitive environment, an organization needs a secure, reliable, and productive data platform for its business applications. SQL Server provides a platform to build and manage data applications. In addition, it combines data analysis, reporting, integration, and notification services that enable organizations to build and deploy efficient Business Intelligence (BI) solutions. This chapter discusses the importance of a database server. In addition, it provides an overview of SQL...
Internet is eigenlijk al in 1962 genoemd. De Amerikaan J.C.R. Licklider van het Massachusetts Institute of Technology schreef een aantal artikelen over een ‘Galactic Network'. In deze artikelen werd zijn idee naar voren gebracht over een wereldwijd netwerk waar iedereen zijn eigen gegevens beschikbaar kon stellen, en de gegevens van anderen kon gebruiken. Een aantal maanden later werd J.C.R. Licklider (rechts) aangesteld als hoofd computer onderzoek op een afdeling van het Amerikaanse...
Artificial Intelligence (AI) in games is a broad science of creating intelligent non-player components (NPC) and game agents (GAs). The huge increase in the processing power of CPU over the past 25 years and the use of dedicated graphics adapters for game graphic needs, game designers are able to implement several additional new features to the game play (A Game Theory Approach to High-Level Strategic Planning in First Person Shooters, 2008). This has shifted the attention towards implementing...
The environment where localization is performed is known beforehand and can therefore be prepared to actively support positioning. That is, fixed reference units can be deployed in this environment, from the interaction of which the location of a mobile target can be derived. . A 2D or 3D geometric location model can be applied to describe location information. This would typically be a local Cartesian or polar coordinate system, delivering x, y and z coordinates, or latitude, longitude and...
Many descriptive and symbolic techniques for representation of the simulation of a model are present in literature. Some of these techniques are better with one model while not better with the representation of the other one. Two most important techniques for representation of model simulation are known as Activity Cycle Diagram and the Condition specification. The activity cycle diagram (ACD) has been used an ideal technique to represent a model. The technique is based on Tocher's idea of...
1. Introduction In 1990, Tim Berners-Lee of CERN (the European Laboratory for Particle Physics) built his first browser and editor called the World Wide Web and the first web server called HyperText Transfer Protocol (HTTP). He proposed a project based on hypertext concept, to help/assist in sharing and updating information among researchers. World Wide Web is an abstract imaginary space of information but search engine was designed as a tool to search for information on the World Wide...
