The huge investment in 3G mobile licences is an incentive to develop extra services above and beyond basic telephony and data services. Service control provides an infrastructure to deliver services, particularly those of a real-time nature. This paper focuses on the progress in developing service control in the context of the 3GPP Release 4/5 network. To achieve the objectives for service evol...

The goal of this study is twofold: first, to examine in greater depth the claimed contribution of differences in syllable structure to measures of speech rhythm for three languages that are reported to belong to different rhythmic classes, namely, English, Spanish, and Catalan; and second, to investigate differences in the durational marking of prosodic heads and final edges of prosodic constit...

Hierarchical structure in bird-habitat associations can arise from hierarchical structure in environmental variables and from the scale-dependent responses of birds to habitat. Hierarchical structure in environmental variables is expected to result from interactions between variables that differ in grain size (spatial resolution) and frequency, and should occur commonly. Birds cannot accurately...

this paper describes 3d-qsar analysis and biological evaluation of 1,5-benzodiazepine analogues. benzodiazepine nucleus with its simple structure gives a good opportunity for further modification regarding an increase of its antimicrobial activity. we synthesized a series of benzodiazepine analogues from condensation of various chalcones and halo substituted o-phenelynene diamines. all compound...
