A multiuser beam-free circular adaptive active array is considered. Such antennas can be used instead of standard multisector antennas. The multiuser beam-free method implies that coverage area is not divided into cells with different frequencies. Instead, all the users can use all the frequencies and active array selects signals by their position. The comparison of the standard multisector antennas...

In SRC RF TRINITI the physics of radiating Z pinches for application as a source of x-ray for ICF target ignition are under investigation. Simultaneously the works on a designing the module of the generator “Baikal” [1] which should deliver the current pulse up to 50 MA as a driver for radiating Z pinch are designed by co-operation of the RRC the Kurchatov Institute, the SRC RF TRINITI, the SUE NIIFA...
Measurements of spatial shape of wire array produced Z-pinch is described. Nonsymmetry of the cathode and anode regions of pinch was observed. According to different spectra of X-ray emission emissive aria separates on two zones. For a single array an analogue of a ≪zipper effect≫ is observed: a hot zone appears at the cathode and expands towards the anode.
Advances in VLSI technology have made it practical to build special purpose processors to replace many of the sequential algorithms that are currently the bottlenecks in information processing. At TRW we have applied this approach to developing a text search and information dissemination system. The key component in this system is the Fast Data Finder, a single-chip text search engine with a pipelined...
