Previous work has studied the use of interval representations in XCS to allow its use in continuous-valued environments. Here we compare the speed of learning of continuous-valued versions of ZCS and XCS with a simple model of an online environment.

This article studies the performance of Quantized State System (QSS) algorithms in the simulation of Switched Mode Power Supplies (SMPS). Under realistic modeling assumptions, these models result stiff and exhibit frequent discontinuities making them difficult to simulate by classic solvers. However, there are Linearly Implicit QSS (LIQSS) methods that can efficiently handle these types of syst...

With the desire to integrate power converters into larger systems, high power density became a very important issue. In this paper we discuss the thermal limits of the power density of converter systems. It is shown that these limits are partly given by today’s technology and partly given by physics. Employing the given equations, one can quickly estimate the maximum possible power density of a...

AbstrAct Limited studies have investigated online consumer loyalty and retention from a relationship orientation in electronic commerce research. It is important to understand the differences in relationship orientations between people who have the propensity to stick to particular Web sites (" stayers ") and people who have the propensity to switch to alternative Web sites (" switchers "). Thi...

Power converters in the accelerator context are often required to deliver a performance that is unusual in an industrial context. This paper deals with some of the important aspects of high-precision output voltage and current control and in particular the current measurement transducers and their application.

Detailed analysis and parameter design for a resistorcapacitor-diode (RCD) clamped snubber used in the output rectifier of phase-shift full-bridge zero-voltage-switching (PS-FB-ZVS) converters are presented. Design equations and some properties of the clamped circuit are highlighted.

Much of the literature on industry evolution has found firm dynamics to be an important source of sector-level productivity growth. In this paper, we ask whether the delineation of entry and exit firms matters in assessing the impact of firm turnover. Using detailed firm level data from Vietnam, it emerges that efficiency differences between sector switchers and exit/entry firms exist. Distingu...

AbstrucGIn this paper an algorithm for piecewise-linear network state-determination is presented. The algorithm is capable of solving networks that contain piecewise-linear elements with discontinuous characteristics, frequently encountered in power electronics. No prior knowledge about the network operation is required. The algorithm has been implemented in a time-domain simulator for power el...
