Over the last few years there has been increasing need for systematic and straregically designed experiments of surface morphology evolution resulting form ion bombardment induced sputtering. Although there is an impressive number of investi­ gations {1} concerned with semiconductor materials as a result of immediate applications, the most systematic investigations have been conducted with fcc metals with particular interest on single crystal ...

The main objective of this book "Design and Analysis of Shorted Gap-Coupled Patch Antenna" is to investigate the gap-coupling technique of bandwidth enhancement. The size of the antenna has been reduced by using the shorting pins and slot loading which results in shifting of resonance from higher to lower frequency. The patch antenna investigated in this book is capable of operating in the L-Band i.e. 1.5-2GHz. It has several applications. The...

Protection of enterprise networks from malicious intrusions is critical to the economy and security of our nation. This article gives an overview of the techniques and challenges for security risk analysis of enterprise networks. A standard model for security analysis will enable us to answer questions such as "are we more secure than yesterday" or "how does the security of one network configuration compare with another one". In this article, ...

Data warehousing and data mining provide techniques for collecting information from distributed databases and for performing data analysis. The ever expanding, tremendous amount of data collected and stored in large databases has far exceeded our human ability to comprehend--without the proper tools. There is a critical need for data analysis that can automatically analyze data, summarize it and predict future trends. In the modern age of Inte...

The area of food adulteration is one of increasing concern for all those in the food industry. This book compares and evaluates indices currently used to assess food authenticity.

In the book the intent is to explain utilization of Semantic Web for the enhancement for Web advertising and Software engineering. It spans around two areas: 1) It proposes a conceptual model that utilizes the concept of pragmatic patterns and semantic web for targeted advertising of products. It acts as a broker providing a web service that maximizes precision of advertising by using contextual elements like the community of use, its objectiv...

Digital watermarking is a method in which the information is embedded directly and imperceptibly into digital data. Potential applications of digital watermarking include copyright protection and authentication. In this monograph a set of novel and generic watermarking scheme has been developed for colored digital images that can embed a holographic logo or a meaningful text. The general watermarking mechanism has been discussed in chapter 1, ...

The protection of environment presents a most fundamental challenge to the nation's desire to industrialize faster and to be capable of fulfilling certain basic needs of the growing population. During development process a huge damage has been caused to the environment because it has resulted into the pollution like deforestation, air and water pollution, etc. Indian government has passed many legislations foe environmental protection e.g. Env...

This book targets research scholars and students interested in neural networks and its applications. It illustrates the efficiency of various algorithms over different types of data sets using bar graphs. Various Neural Network Algorithms are studied and made run on same data set to find out efficiency of each algorithm and the output of all these algorithms are compared. Neural Network Algorithms used are: Decision Tree Forest, Cascade Correl...

Nowadays hi-tech secure products need more services and more security. Furthermore the corresponding market is now oriented towards more flexibility. Thus, this book presents implementation of the Advanced Encryption standard (Rijndael) and compares how it performs on different platforms. In this book, the Advanced Encryption Algorithm is implemented for ARM based platforms. Although the AES is fully defined in terms of functionality, it requi...

One's best teacher it is always one's best experience. The anterior lingual seal in a mandibular denture, PPS in a maxillary denture, and achievement of a balanced occlusion determine the high quality of complete denture prosthesis. Text book on Clinical perspective of complete denture prosthodontics provides basics and different treatment modalities in three parts. First part has comprehensive intraoral techniques for the posterior palatal se...

Food safety is a global concern and increasing use of food additives pose a threat to human health. Artificial sweeteners are being sold and consumed at a fast pace in the Indian market by the urban population. Therefore a study was conducted to check the availability of artificial sweeteners and their pattern of consumption among diabetics, overweight people attending a weight loss program in a slimming center and college girls. The study was...

People are likely to surf the web using search engines. Crawler (a part of search engine) continuously crawls the web and keeps its collection as fresh as possible. An efficient crawler should address issues like unnecessary burden on the web crawler, parallelism of the crawling process, freshness of the web contents discovered and revisiting frequency of web pages. When pages are changing very fast then these crawlers need to visit the pages ...

In recent years, it has become clearly recognized that many behavioural disturb­ ances and psychiatric illnesses are intimately associated with alterations in neuroendocrine function. This volume is designed to provide a thorough, up-to­ date review of our current knowledge of the neuroendocrine correlates of altered behaviour in man and experimental animals. Particular emphasis has been focused on the mechanisms which may underlie the couplin...

AIDS is the leading cause of death in Africa, where 28 million people are HIV positive and 12 million children have lost parents to AIDs. This work depicts the reality of how these children deal with the AIDs epidemic, and how the discourse of their vulnerabilty affects acts of courage.

This edited volume includes all papers presented at the 22nd International Conference on Mine Planning and Equipment Selection (MPES), Dresden, Germany, 2013. Mineral Resources are needed for almost all processes of modern life, whilst the mining industry is facing strict requirements regarding efficiency and sustainability. The research papers in this volume deal with the latest developments and research results in the fields of mining, machi...

Photobiology is an important area of biological research since a very large number of living processes are either dependent on or governed by light that we receive from the Sun. Among various subjects, photosynthesis is one of the most important, and thus a popular topic in both molecular and organismic biology, and one which has made a considerable impact throughout the world since almost all life on Earth depends upon it as a source of food,...

Plant productivity depends upon the photosynthetic conversion of the light energy into chemical energy stored in the biomass of plants. An intermediate step in this energy conversion process is electron transfer and proton translocation. At present, several research groups are working on projects that are expected to lead to rapid improvement of our understanding of the photosynthetic process. This book is a compilation of the work being done ...

Present book provides an insight to the synthesis, characterization and structural analysis of compounds containing nitrogen and sulfur containing chelating agents. Keeping in mind the biological, medicinal, industrial and chelating importance of sulfur (alone) and nitrogen containing donor ligands, two important chelating agents, viz Potassium-2-trithiocarbonatoethyl xanthate (PTEX) and 2-amino-4-benzamido thiosemicarbazide (ABTSC) have been ...
