In the third generation networks a quality of service is guaranteed for key applications, such as video streaming. However, all the packets belonging to one application are handled in the same way, even though they have different impact on the perceived quality. In this article we present a standard compliant cross layer optimization for video services. The importance of a packet, signalized at...

A worldwide increasing demand for wireless communication services signals a new era for networks and their germane protocols. Wireless ATM is designed to provide high speed isochroous and asynchronous communications for users who may demand high-speed data communications along with audio and video conferencing capabilities is proposed as a solution for the provision of these services. This pape...

A One-Dimensional (One-D) numerical model to calculate transient temperature distributions in a liquid-piston compressor with porous inserts is presented. The liquid-piston compressor is used for Compressed Air Energy Storage (CAES), and the inserted porous media serve the purpose of reducing temperature rise during compression. The One-D model considers heat transfer by convection in both the ...

The goal of this research is to optimize PHA production in the syngas fermenting organism Rhodospirillum rubrum. Syngas fermentation is the hybrid thermochemical/ biological approach to processing biomass into valuable fuels and chemicals. The process begins with the gasification of biomass to produce syngas, a flammable gas mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), a...
