It is shown that various sets of state variables have a common theoretical background that simplifies the deduction of the saturated models. The possible combinations of the state variables are grouped in two classes for which are established direct calculus algorithms. (1) The winding currents -flux linkages as state variables. (2) The magnetizing current im -currents (flux linkages) of the windings as state variables. Specific computations are performed and there are written the state equations of the electromagnetic processes for several combinations of the state variables. The major aim of the numerical approach is to compare the computational programs. The simulation results points out that in the presence of saturation the simplified models do not reveal in a correct way the complete evolution of the dynamic electromechanical processes. The dynamic variation of the saturation (Ldqne0) essentially justifies the forced electromechanical oscillations.","PeriodicalId":191423,"journal":{"name":"EUROCON 2007 - The International Conference on \"Computer as a Tool\"","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114228404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have the ability to radiate in an ultrasonic medium, e.g. water, with maximum acoustic power when the vibration is activated by a current whose frequency equals the mechanical resonance frequency of the transducer. In resonant inverters the transducer units are part of the oscillating circuit, for which equivalent electrical circuit consist of connection in parallel: Co end RLC. Genetic algorithm is used to optimization of structure and parameters piezoelectric ceramic transducer. Genetic algorithm have been shown to be effective in the resolution of difficult problems. The resonant frequency of the real circuit varies during the operation in function of many parameters, among others, the most important are temperature, time, the column of cleaning factor, and the surface of the cleaned elements.

In this paper we propose a scalable, fault tolerant communication framework based on the peer-to-peer paradigm. The framework's design is oriented towards high volume point-to-point and multicast data delivery. The proposed system uses balanced message flow distribution over multiple paths in order to achieve high throughput and the lexicographic distance between the peer's names in order to guarantee that the message flow converges to destination.","PeriodicalId":191423,"journal":{"name":"EUROCON 2007 - The International Conference on \"Computer as a Tool\"","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124512816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A-TS uses a novel approach for evaluation of the moves, incorporated in a new complex evaluation function. A new decision making mechanism triggers the evaluation function providing means for avoiding possible infinite loops. The new evaluation function implements effective diversification strategy that prevents the search from stagnation. It also incorporates two adaptive coefficients that control the influence of the aspiration criteria and the long-term memory, respectively. The adaptive nature of A-TS is based on these two adaptive coefficients. This article also presents a new data mining approach towards improving the performance of A-TS by tuning these coefficients. A-TS performance is applied to the Quadratic Assignment Problem. Published results from other authors are used for comparison. The experimental results show that A-TS performs favorably against other established techniques.","PeriodicalId":191423,"journal":{"name":"EUROCON 2007 - The International Conference on \"Computer as a Tool\"","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127710000","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
