There is a spate of research activities investigating digital image watermarking schemes in an effort to control the problem of illegal proliferation of creative digital data across the Internet. Several schemes, with their merits and demerits, have been proposed to date. However, many of them rely on the presentation of a test image in an appropriate format before the detection can proceed. In...

Purpose – To identify the pros and the cons of Google Scholar. Design/methodology/approach – Chronicles the recent history of the Google Scholar search engine from its inception in November 2004 and critiques it with regard to its merits and demerits. Findings – Feels that there are massive content omissions presently but that, with future changes in its structure, Google Scholar will become an...

A large amount of energetic materials including propellants, high explosives, pyrotechnics are subjected to disposal either due to expiry of their useful life or rejection in the manufacturing process. The environmental regulations do not allow the hazardous materials for open burning / detonation in view of the health hazard involved in these operations. The present paper describes the hazard ...

We discuss techniques for Voice Activity Detection (VAD) for Voice over Internet Protocol (VoIP). VAD aids in saving bandwidth requirement of a voice session thereby increasing the bandwidth efficiently. In this paper, we compare the quality of speech, level of compression and computational complexity for three time-domain and three frequency-domain VAD algorithms. Implementation of time-domain...

Maps and spatial descriptions are two different styles in expressing geographical information. Each style has its own merits and demerits. When information is given in one style, it is sometimes required to convert it to the other style. A vast amount of spatial descriptions are available electronically, especially on the World Wide Web. If geographical knowledge extracted from spatial descript...

Abstarct The work presents the newly deploying technology in semiconductor industry called silicon on insulator (SOI). Its two technology partially and fully depleted SOI and describe how these are different from conventional bulk MOS technology, advantages over bulk technology and floating body effect of PD/FD SOI technology, factors effecting floating body such as kink effects in PD SOI, para...

The objective of this article is to audit the tracking strategies, characterize them into distinctive classifications, further more distinguish new patterns. Tracking the targets undergoes various classic problem because of variety of reasons, including camera movement , illumination variability, occlusions and drift problem. To give an improvement to the solution of drift problem in online tra...

In this chapter, we look at the general architecture of a peer-topeer system and contrast it with the traditional client-server architecture that is ubiquitous in current computing systems. We then compare the relative merits and demerits of each of these approaches toward building a distributed system. We begin the chapter with a discussion of the client-server and peer-to-peer computing archi...

Concept of probiotics in clinical practice is not new. But in general its use was limited due to lack of confidence of the clinicians and inadequate knowledge of merits and demerits of different probiotics. Over the years researchers have explained the beneficial effects and risks associated with the use of various products. Many things regarding its mechanism of action, microbiology, immunolog...

SUMMARY In biological assays, clinical trials, life-testing problems, reliability and survival analysis, and a variety of applied fields ranging from agrometry to biodivrersity to zodiacal sciences, generalized linear models covering usual linear, transformed linear, log-linear and nonlinear regression models, multi-nomial and logistic regression models, as well as some semiparametric ones, are...
