This thesis investigates Learning Classifier System architectures for decision making in continuous-valued domains. The information contained in continuous-valued domains is not always conveniently expressed using the ternary representation typically used by Learning Classifier Systems and an interval-based representation is a natural choice. Two intervalbased representations recently proposed ...

The analysis for a given Soft-Switching DC-DC converter family can be generalized using the switching-cell of that family leading to a number of generalized equations with a Transformation Table. In this paper, the concept of generalization and step by step procedure for the generalized process are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, ZCS-CC QSW,ZV...

We investigate Learning Classifier Systems for online environments that consist of real-valued states and which require every action made by the agent to count towards its performance. Two Learning Classifier System architectures are considered, ZCS and XCS. We use an interval representation with these Learning Classifier Systems for the rule conditions together with roulette wheel action selec...

This paper presents mechanical characteristics of Switched Reluctance Motor (SRM) when it operates in Discontinuous Conduction Mode (DCM) or in Continuous Conduction Mode (CCM), i.e. when the current through the phase coils (windings) flows discontinuously or continuously. Firstly, in order to maximize the output power of SRM optimization of its control parameters was performed, such that the p...

82 IEEE Concurrency R symmetric multiprocessor systems have become widely available, both as computational servers and as platforms for high-performance parallel computing. The same trend is found in PCs—some have also become SMPs with many CPUs in one box. Clusters of PC-based SMPs are expected to be compact, cost-effective parallel-computing platforms. At the Real World Computing Partnership,...

In this paper we investigate a tunable MPI collective communications library on a cluster of SMPs. Most tunable collective communications libraries select optimal algorithms for inter-node communication on a given platform. We add another layer of intra-node communications composed by several tunable shared memory operations. We explore the advantages of our approach, and discuss when to use ou...

The coupling of SMPS and ICPMS will allow achieving size and chemical information at the same time. The expected full size range scan duration of several minutes and the even shorter scan times for narrower size ranges will enable transient particle observation, and it opens the possibility to chemically characterise an aerosol in its original condition instead of sampling particles first and a...

We discuss the possibility of light control by means of light diffraction by space charge waves which are the periodic domain trains induced at some circumstances in GaAs Gunn effect diode. The two possible regimes of the proposed device are considered: the first one which is analogous to the Bragg diffraction in case of light-acoustic diffraction and the other one, which we call “intermediate”...

The design and breadboard implementation of a constant-frequency, zero-voltage-switched, full-bridge pulsewidth modulation converter delivering a 12-V-at-1-kW output from a 350–450-Vdc input bus is described. The zero-voltage switching characteristic is maintained over a wide operating range by utilizing the transformer magnetizing inductance as an energy storage element. Output voltage regulat...

A three-dimensional conduction model has been developed to predict the transient temperature distribution inside a thick solid that is irradiated by a moving laser source, and the changing shape of a groove carved into it by evaporation of material. The laser may operate in CW or in pulsed mode with arbitrary temporal as well as spatial intensity distribution. The governing equations are solved...
