CVD on Iron Powder - Using Fluidising Bed Techniques

Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. Soft Magnetic Composites

Privacy preserving neighborhood awareness in vehicular ad hoc networks

Location information is exchanged among members of Vehicular Ad Hoc Networks (VANET) to serve many road and safety applications. Vehicles will announce their identity, position, and mobility information to their neighboring nodes. The importance of such information makes privacy a major concern. Successful implementation of VANET requires protecting the vehicle's identity at all times and preventi

Precision Issues in the implementation of BCJR decoders

The BCJR algorithm is a symbol-bysymbol soft-output MAP decoder for trellis codes. This paper studies the effect of wordlength variations on the BCJR performance and looks at two strategies for reducing the wordlength.

On the extraordinary transmission through sub-wavelength apertures in perfectly conducting sheets

Extraordinary transmission of electromagnetic power through sub-wavelength apertures is usually observed in a narrow bandwidth range and the transmission outside this range is low. In this paper, it is shown that the transmission through periodic apertures in an otherwise perfectly electric conducting sheet satisfies a sum rule that relates wavelength regions with transmission above a threshold wi

Improving the energy efficiency of accelerator facilities

New particle accelerator based research facilities tend to be much more productive, but often in coincidence with higher energy consumption. The total energy consumption of mankind is steeply rising and this is mainly caused by quickly developing countries. Some European countries decided to terminate nuclear power generation and to switch to sustainable energy production. Also the CO2 problem giv

US v Brazil - Compulsory licensing

Referring to case development in the WTO dispute resolution system the authors discuss compulsory licensing in the developing world in line with their published articles on “Facilitating compulsory licensing under TRIPS in response to the AIDS crisis in developing countries” and “Embracing price discrimination: TRIPS and the suppression of parallel trade in pharmaceuticals”.
