Hypersonic Leeside Delta-Wing-Flow Computations Using Centered Schemes

Abstract: In recent years research investigations have enhanced considerably our knowledge about the flow over the leeside of a delta wing in low and transonic speeds. But we still know relatively little about the corresponding flow in hypersonic speed. The flow here is very near to vacuum, and the extent of vortical flow structures, if any, is not generally known. The purpose of this work is to study the leeside flow over a thick blunt- edged delta wing of 70° sweep at M ∞ = 7.15 and α = 30° by means of numerical simulations using the Euler and Navier- Stokes equations.

ACE and the Future of Antenna Research in Europe

Abstract: ACE, the Antenna Centre of Excellence, is a Network of Excellence funded by the European Commission. Its purpose is to restructure the scattered European antenna research. Starting 1 January 2004, it has a duration of 4 years and 51 participants from 17 European countries. 323 researchers and 130 PhD students are involved. (8 pages)

Safety-specific analysis as additional design assurance for microprocessors

Abstract: In this paper we discuss the use of safety- specific analysis (SSA) as additional design assurance of modern microprocessors. SSA is a method to derive and validate safety-specific requirements about internal operations of a component. We suggest and discuss a mixed component assurance approach based on on-chip service history, on-chip architectural mitigation techniques (including turning off some parts) and safety- specific analysis on different parts of the microprocessor. With this approach we believe that it might be possible to gain certification credit for the complete microprocessor even if some on-chip parts are partially or even completely new. We also show why it will be very hard to perform safety-specific analysis on a complete modern microprocessor. A modern microprocessor is simply too complex and manipulates data in a too complex manner to be able to analyze for safety- specific aspects.

Antennenvorrichtung zur Radar-Füllstandsmessung

Abstract: Antennenvorrichtung (14) fur ein Radar-Fullstandsmesgerat (11), das an einer Offnung (12) in einem Dach (13) eines Tanks befestigt ist, wobei diese Antennenvorrichtung mindestens eine langliche Abstrahlungsstruktur (15; 32; 41; 51) umfast, dadurch gekennzeichnet, das diese mindestens eine langliche Abstrahlungsstruktur (i) eine Lange (1) aufweist, die erheblich groser ist als eine maximale Querschnittslangenabmessung (d) der Offnung; (ii) klein genug ist, um durch die Offnung in den Tank eingefuhrt zu werden; (iii) in einer nicht vertikalen Stellung ausgerichtet ist; und (iv) konfiguriert und gespeist ist, um ein im wesentlichen vertikales Strahlenbundel zu erzeugen, das nach unten in den Tank gerichtet ist.
