The aim of the European project MASTER (MAnaging Speeds of Traffic on European Roads) is to produce information that can be cited in the preparation of national and EU decisions concerning speed management and standards for speed control equipment. For this purpose, the project seeks answers to three key questions:1) What are acceptable ranges of speeds?2) What are the key factors influencing dri

In this paper we consider fundamental limitations for DOA estimation with arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical vector modes and their associated equivalent circuits and Q factor approximations are employed as a general framework for the analysis. The classical broadband matching theory by Fano is extended to a general multiport S–parameter model of the

An 8-GHz beamforming transmitter IC has been designed in a 130-nm CMOS process. Two power amplifiers with independently controllable phase enable the beamforming. The phases are digitally controllable over the full 360◦ range, which is accomplished by binary weighting of quadrature phase signals in the power amplifiers. The quadrature phase signals are generated by a quadrature voltage controlled

This paper overviews new methods for fast correlation attacks on stream ciphers, based on convolutional codes. Identification of embedded structures of concatenated convolutional codes (both parallel and serial) in the shift register code, providing increased performance, is considered.
