Numerical magnetic field analysis is used for predicting the performance of an induction motor and a slip‐ring generator having different faults implemented in their structure. Virtual measurement data provided by the numerical magnetic field analy

The basic ideas of feedback and control are not difficult to understand. However it is an interesting challenge to demonstrate control techniques in an entertaining and attractive way. The ball balancing device presented in this paper was developed t

A metacompiler for translation of knowledge representation formalisms is presented. The metacompiler, R&CL, has been used extensively for declaring natural language processing formalisms. The syntax and semantics of target languages are defined using

Two simple algorithms are used to find the global optimum in a parameter space of high dimension. Both algorithms are based on local optimization-the first one uses the gradient method, the other one modified Kohonen nets. The main topic of interest

The paper presents a novel idea of a behavior-based self-organizing map. The self-organizing map (SOM) is extended to cover 'objects' that interact with their environment. They are organized based on their behavior instead of parameterized presentati
