One contribution of this paper consists in diagnosing most precisely the problems due to the compression and the packet losses for two different recognition tasks: the automatic speech recognition and speaker recognition. Another contribution corresponds to the proposal for recovering techniques in order to improve the robustness of systems under significant packet losses conditions. From the diagnosis, a more important degradation due to the compression on the speaker verification task was noted. The experimental results show that the techniques of interleaving based on the transmitter combined with the interpolation based on the receiver, prove to be the most efficient","PeriodicalId":125310,"journal":{"name":"2006 3rd International Conference on Electrical and Electronics Engineering","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121548327","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}

In small residential PV applications, the power ratio is usually calculated during system design and specification stage, by determining the peak PV power from guidelines given by the inverter manufacturer, without a detailed analysis of the solar resource's magnitude or its characteristics at the site of the application. On the other hand, the inverter input CD voltage, determined by the electrical configuration of the PV array. In operation, this voltage varies in relation to the irradiation and temperature of the PV modules. Likewise, the stability of the inverter output AC voltage (voltage from the grid at the point of connection) depends directly on \"the strength\" of the grid to which the PV plant is connected.

The mathematical model of the rotor system results from a Jeffcott model and the dynamics associated to the MR dampers, whose properties depend on the current inputs (control actions). There are different models for MR dampers proposed in the literature, most of them experimentally validated. For control purposes we use the Choi-Lee-Park polynomial model, which is quite consistent with the nonlinear and complex hysteresis damper models and also simplifies the physical implementation. The semiactive control scheme is then analyzed and synthesized to manipulate the unbalance response of the rotor system, by means of a proper modification of the rotor dynamics coefficients (damping and stiffness) using sliding-mode control techniques","PeriodicalId":125310,"journal":{"name":"2006 3rd International Conference on Electrical and Electronics Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125341413","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}
