Publikováno v: Vehicle System Dynamics. 20:299-313

SUMMARY The following study provides new strategies for suspension control of a railway carriage subjected to random track disturbance. We have numerically implemented different active and semi-active suspensions in a model of carriage of twelves deg

Publikováno v: 2007 European Microwave Conference.

In spite of the establishment of threshold exposure [1] [2] and their taking into account in the legislation [3] [4], most of interrogations of general public remains focused on the field radiated base stations levels. To know the reality of these pe

Publikováno v: IEEE MTT-S International Microwave Symposium Digest, 2005..

An original implementation of a receiver for UMTS numerically-controlled smart base-stations is proposed in this paper. A complete analog front-end is inserted within a hybrid-radiating module. The module uses original conformal patches inserted in a
