Rapid prototyping of complex systems embedded in even more complex environments raise the need of a multi-level design approach. Our example is taken from mechatronic design of the automotive industry and illustrate the rapid prototyping procedure of real-time critical control laws. Our approach is based on an object oriented structuring allowing not only(More)
The implementation of large linear control systems requires a high amount of digital signal processing. Here, we show that re-configurable hardware allows the design of fast yet flexible control systems. After discussing the basic concepts for the design and implementation of digital controllers for mechatronic systems, a new general and automated design(More)
We report the presence of two disconnected superconducting domes in the pressure-temperature phase diagram of partially germanium-substituted CeCu2Si2. The lower density superconducting dome lies on the threshold of antiferromagnetic order, indicating magnetically mediated pairing, whereas the higher density superconducting regime straddles a weakly(More)
We report on a comprehensive study of CePd(1-x)Rh(x) (0.6 <or= x <or= 0.95) poly- and single crystals close to the ferromagnetic instability by means of low-temperature ac susceptibility, magnetization, and volume thermal expansion. The signature of ferromagnetism in this heavy-fermion system can be traced from 6.6 K in CePd down to 25 mK for x = 0.87.(More)
Investigations of the susceptibility, electrical resistivity, specific heat and thermopower of CeTiGe at low temperatures show that this compound is a Kondo lattice system with an enhanced Sommerfeld coefficient γ≈0.3 J K(-2) mol(-1) and where the whole J = 5/2 multiplet is involved in the formation of the ground state. No magnetic order was observed down(More)
Neutron diffraction experiments have been performed on a magnetically ordered CeCu2Si2 single crystal exhibiting A-phase anomalies in specific heat and thermal expansion. Below T(N) approximately 0.8 K antiferromagnetic superstructure peaks have been detected. The propagation vector of the magnetic order appears to be determined by the topology of the Fermi(More)
