Expert Control

There has been substantial progress in the theory and practice of automatic control through application of mathematical analysis and numerics. Symbolic data processing has, however, so far only had marginal influence on control systems despite the fact that the actual engineering of control systems contains a substantial amount of heuristic logic. This paper shows how the logic may be replaced by

Comparison of angular and delay spreads between channel measurements and the COST channel model

The COST2100 channel model is a reference channel model which provides dynamic multiple-input multiple-output channel responses for radio system simulations. In this paper, channels created by the COST2100 model were compared to channel measurements in order to understand behaviours of the model. Model parameters of the COST2100 model were derived by dynamic double-directional channel measurements

Use of environmental requirements in the supply chain relations: some experiences from Poland and Sweden.

Growing number of ISO 14001 certifications worldwide creates new possibilities for organizations to benefits from the global recognition of the standard. One of them is unequivocally the use of ISO14001 certificate as one of conditions for supply chain cooperation. Such situation pulls many enterprises into implementation of the systems for the bare reason of fulfilling the requirement, abreast to
