The use of intelligent systems and machine learning methods, capable of automatic decision making based on already solved cases, and data mining, are getting more and more popular. Here we are faced not only with technical problems, but also with limited confidence in machine learning techniques. In some cases methods that may explicitly show the deduction process are not powerful enough. One of the possibilities is to modify/improve the methods so that the users could easily follow the process of decision making. To solve this problem, a few years ago we started to develop a platform, which enables us to develop, test and use different kinds of hybrid methods. These are meant to combine the advantages of the integrated methods-e.g., power and knowledge representation-that contribute to the quality of the acquired knowledge. In this paper we present a way of using the developed platform in order to obtain new knowledge, based on results from neurophysiological measurements We are every pleased with the performance of our intelligent platform. The first results we obtained already show some improvement in comparison to classic machine learning approaches.

Connecting COTS (Commercial-off-the-Self) simulation packages entails various difficulties. First of all, commercially available simulation packages hide the access to some internal data that is needed to connect to other simulation models in the distributed simulation study. Next, the data sharing between simulation models is complicated. In order to carry out distributed simulation studies applying COTS simulation packages, we have to exactly define the interfacing and data transfer mechanisms. In this paper we present a theoretical description of different solutions for interfacing and transferring data between various simulation models. These mechanisms have been implemented and tested, and applied in a project in order to prove their practical usage.

In this paper, we develop a 4-DOF force display system for the analysis by synthesis of facial color for the interaction with anthropomorphic agent. By using the system, we analyze the changes in facial skin temperature and facial color associated with circulation dynamics in response to forced actions. On the basis of the analysis, we propose a synthetic method for the affect display of virtual face with facial color and expression in force display, and the effectiveness of the method is confirmed. Finally, we develop a prototype of virtual arm wrestling system with anthropomorphic agent using synthesized dynamic three-dimensional facial color and expression.
In their paper [6], Leger and Luks introduced the notion of a gener- alized derivation in nonassociative algebras and got several results for generalized derivations of Lie algebras. This generalized derivation is clo...

A successful application of a new intelligent system design approach called Multimethod in knowledge extraction and discovery in heart attack areas is presented in this paper. The results show that the Multimethod approach is a powerful and promising technique enabling the conformation of existing medical knowledge and more interestingly, also enabling the induction of new facts and hypothesis, which can reveal some new interesting patterns and possibly improve the existing medical knowledge.

This paper is concerned with an application study of model-based fault detection method to a ship propulsion system. When modeling the object system, Quasi-ARMAX model with multi-model form is used. In this model, the system non-linearity is incorporated into model parameters by using non-linear non-parametric models (NNMs). Kullback discrimination Information (KDI) is introduced as fault detection index to evaluate the distortion in identified model, which is caused by a fault. The effectiveness of the method is verified through simulation studies on the ship propulsion system.

A test structure combined with a ring oscillator, an inverter chain and an embedded monitor inverter, which allows accurate internal node access, is proposed. V/sub dd/ and well-bias dependence of gate delay and supply current measured by both ring oscillator and inverter chain scheme. V/sub T/ control method by well biasing, particularly to forward direction, is effective for high speed operation under low supply voltage. The new test structure can be utilized to evaluate optimum conditions for high-speed/low-power operations as well as high-reliability operations.
