Modern magnetic materials are often composed of several elements, each of which contributes in a specific manner to the global magnetic properties. In order to understand the magnetic behavior of a complex compound on the basis of its constituents, the magnetic state of an individual sort of atoms must be determined. Such an element-selective probing of magnetic atoms can be conveniently achiev...

We describe an approach to designing CAN-based distributed real-time systems so that safety is preserved regardless of timeliness. Our approach offers gains with respect to both fault tolerance and flexibility aspects and so it is attractive to support those systems that have critical tasks (e.g. control systems) and at the same time are connected to non-predictable networks (e.g. the Internet).

Based on the VMS survey of the compact array antenna CA02, the effects of gravity deformation were examined in AT 39.3/115. The dominant cause of gain loss and beam distortion was identified to be the deformation of the main reflector surface with elevation. This report examines whether active displacements in the sub-reflector and/or feed might compensate for the aperture wavefront errors. All...

This paper focuses on the concept of a psychological contract. It argues that research analyzing the employment relationship through this concept tends to overlook the constraints which actually mark the actors' behavoirs. A lot of papers dealing with the Psychological contract approach conveys the view of a free actor. To support this thesis, this paper will first review some of the main featu...
