We will discuss the application of coherent software radio technology to remote sensing of the ionosphere. Using networks of advanced software radio systems it is possible to make observations of the ionosphere with both wide spatial coverage and simultaneous high resolution in space and time. Such observations can be made using a variety of techniques such as active and passive multi-static radar...
The unique and powerful diagnostic capabilities of low radio frequencies for solar, heliospheric, and ionospheric science have long been recognized, but the challenges associated with high-fidelity low frequency radio imaging have limited their exploitation. The Murchison Widefield Array (MWA) is a pioneering new interferometer, currently under construction in the radio-quiet Western Australian outback,...
This paper discusses a methodology used on an industrial hardware development project to validate various cache-coherence protocol components. The idea is to use a high level model (HLM) written in Murphi for model checking purposes, and then to use the HLM as a checker during dynamic (i.e. simulation based-) validation of the RTL. Such a checker requires a formal notion of what it means for the RTL...
