A simple model is presented to describe how the radio frequency electromagnetic field modifies plasma density antenna faces in tokamaks. Aside from “off-the-shelf” equations standardly used wave-plasma interaction relying on quasilinear approach, it invokes ponderomotive force presence of confining static magnetic field. The focus dynamics perpendicular Bo Stronger fields result being pushed fu...

UNLABELLED BEAUTY (BLAST Enhanced Alignment Utility) is an enhanced version of the BLAST database search tool that facilitates identification of the functions of matched sequences. Three recent improvements to the BEAUTY program described here make the enhanced output (1) available for DNA queries, (2) available for searches of any protein database, and (3) more up-to-date, with periodic update...

the projection strucrure is vibrated by the dynamic effects of the projectile in the inital stahes before seperation. this induces two major results, one is the calculation of stresses obtained decause of bib ration in order to design the launcher and other one which. is bery important, is the determinaion of initial condirions of the nissile prijection at the time of fron the launcher. these c...

Unlike a liquid propellant stage which allows stopping the thrust at any time during the flight, when a solid rocket motor is used on a Launcher upper stage, the impact zone can be very large due to the atmospheric and propulsive dispersions on the current stage and the previous stages. In this case a stage impact control is required. In this study, an active impact control strategy is presente...

In this work we show the design and implementation of an efficient telemetry subsystem for Wireless Sensor Networks inside the Vehicle Equipment Bay (VEB) of the ARIANE 5. The telemetry subsystem is utilizing infrared data communication and consists of various smart sensor chips such as temperature sensor, humidity sensor, visible light intensity sensor, infrared light sensor, acceleration sens...
