After the successful global introduction during the past decade of the second generation (2G) digital mobile communications systems, it seems that the third generation (3G) Universal Mobile Communication System (UMTS) has finally taken off, at least in some regions. The plethora of new services that are expected to be offered by this system requires the development of new paradigms in the way scarce radio resources should be managed. The Quality of Service (QoS) concept, which introduces in a natural way the service differentiation and the possibility of adapting the resource consumption to the specific service requirements, will open the door for the provision of advanced wireless services to the mass market.

Introduction Computer security is undeniably important, and as new vulnerabilities are discovered and exploited, the perceived need for new security solutions grows. "Trusted computing" initiatives propose to solve some of today s security problems through hardware changes to the personal computer. Changing hardware design isn t inherently suspicious, but the leading trusted computing proposals have a high cost: they provide security to users while giving third parties the power to enforce policies on users computers against the users wishes -- they let others pressure you to hand some control over your PC to someone else. This is a "feature" ready-made for abuse by software authors who want to anticompetitively choke off rival software. It needn t be this way: a straightforward change to the plans of trusted computing vendors could leave the security benefits intact while ensuring that a PC owner s

游戲開發(fā)數(shù)據(jù)結(jié)構(gòu)Data Structures for Game Programmers The Goodies Directory contains all sorts of stuff. For example, there are the four 3rd-Party libraries used in the book, SDL, SDL_TTF, FreeType (which SDL_TTF uses), and STLPort, which is one implementation of the Standard Template Library. Also, there are four articles on trees and SDL in the articles directory. These supplement the material in the book.

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networks using directional antennas, Smart card application and wireless communication. Also my research idea titled “Wavelet Based Image Compression Using SPIHT Algorithm “secured third prize in a technical festival.
