This paper proposes an input-series-output-parallel connected ZVS full bridge converter with interleaved control for photovoltaic power conditioning systems (PV PCS). The input-series connection enables a fully modular power-system architecture, where low voltage and standard power modules can be connected in any combination at the input and/or at the output, to realize any given specifications...

We present a new system for rating the playing strength of table-tennis players. The system is based on Bayesian principles and is designed to handle a large changing population of players, where some players play frequently whereas other players play infrequently. The system takes into account the length of time since a player last played a tournament. When processing matches in a single tourn...

the selection of erp systems has been considered as one of the most influential and risky managerial decisions due to its heavy burden of purchase and implementation costs. the purpose of this paper is designing a fuzzy expert system for selecting the appropriate erp system based on the internationally selected and validated criteria for minimizing the risks of inappropriate selection. if an op...

dexsy2 is a dental expert system, which diagnoses oral diseases and offers a treatment course. the system which is designed and implemented from scratch is capable of diagnosing among thirty five oral diseases and offering a course of treatment for each. it uses a decision tree for its representation of knowledge, and each of its nodes contains a frame. the knowledge base of the system contains...

In this paper, an empirical evaluation of three infer­ ence methods for uncertain reasoning is presented in the context of Pathfinder, a large expert system for the diagnosis of lymph node pathology. The inference procedures evaluated are (1) Bayes' theorem, a:ssum­ ing evidence is conditionally independent given each hypothesis, (2) odds-likelihood updating, assuming evidence is conditionally ...
