Jeszcze kilka lat temu eksploatacja kosmiczna była istnym science fiction. Jednak dziś - gdy ludzkość coraz trudniej odnajduje kopaliny na lądach – idea taka staje się coraz bardziej realna i wszystko wskazuje na to, że wkrótce wydobywanie surowców z pobliskich ciał niebieskich przestanie być wymysłem fantastów, a stanie się faktem.
With the application and popularization of autonomic computing in the field of aerospace exploration, large-scale database management and critical network control, existing self-reflection models based on natural language or diagram can not meet the requirements of analysis and verification. In this article, two kinds of self-reflection models, one is the static and the other is dynamic, capable of...
The normally off silicon carbide power vertical JFET (VJFET) can perform the role of switch, rectifier, or switch with anti-parallel rectifier. This innovative feature eliminates the need to qualify a separate diode that can withstand the rugged environment of, for example, the surface of Venus on-board a surface planetary probe, or that can be derated to exhibit high-reliability in merely harsh terrestrial...
