Also, the concentration effect, of the polyfunctional monomer TAC (triallylcyanurate) on the physical properties of EVA (ethylene vinyl acetate) rubber and of the CPE (polyethylene chlorinated) rubber, obtained by EB vulcanization, is reported. Several results regarding the effect of simultaneous irradiation with accelerated EB and 2.45 GHz microwaves (MW) on the physical properties of the silliconic rubber containing TAC are discussed. For the proper polyfunctional monomers concentrations and proper EB doses the rubber physical properties are improved with respect to control samples obtained by classical procedure using benzoyl peroxide. The most important result obtained by the EB+MW treatment is the reduction of the EB dose compared to the separate EB irradiation, at the same vulcanization parameters.","PeriodicalId":244464,"journal":{"name":"2008 11th International Conference on Optimization of Electrical and Electronic Equipment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132936994","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}

The method is using the DK5 modeling/design environment from Celoxica and is based on the new Handel-C programming language. The goal of the work carried out was to achieve a combined model of a photovoltaic energy system and a wind power system, which would allow an optimized holistic digital control system design, followed by rapid prototyping of the controller into a single field programmable gate array (FPGA). Initially, the system was simulated using Matlab / Simulink, to create a reference for comparison. Later on, the model was successfully developed in Handel-C. The holistic functional simulation of the system is performed in the same environment as its controller hardware implementation and timing analysis. The controller design was then downloaded in hardware onto a RC100 development board containing a Xilinx Spartan II FPGA and was successfully experimentally tested. This approach enables the design and fast hardware implementation of efficient controllers for distributed energy resource (DER) hybrid systems.","PeriodicalId":244464,"journal":{"name":"2008 11th International Conference on Optimization of Electrical and Electronic Equipment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131909619","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}

The proposed algorithm is applied to the rehabilitation robot FRIEND II for the localization of objects situated in complex scenes. Also, the method was designed to cope with changes in the illumination conditions. The approach used in this work is the inclusion of feedback control in the image processing chain used by the Machine Vision Framework of the robot. A closed-loop control system was designed at image segmentation level for improving the robustness and reliability of the feature extraction module. The design of the closed-loop is based on an Extremum Searching Algorithm which searches for the optimal parameters of the image segmentation method. The performance of the proposed framework is investigated in comparison with a traditional open-loop method.","PeriodicalId":244464,"journal":{"name":"2008 11th International Conference on Optimization of Electrical and Electronic Equipment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125871716","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}

Distant labs, specifically remote labs (RL), are systems which are accessed through a web browser, which allow users from all over the world, anytime to perform the experiments with real devices.

In this study a conceptual model for effectiveness assessment of remote labs is introduced. The model is based on RL interactions with its environment and organizational strategy.

Regardless of their application the fuel cell must be accurately modeled in the system it will be used. Such model has to be simple, easy to use and fast to simulate. Chemistry, material science and physics should be transformed in electrical components and systems that can be easily implemented in programs like SPICE, Saber, Labview, Proteus or similar. In this paper some improvements of a generalized circuit model for a PEM fuel cell that can be used for design and analysis of fuel cell power systems is presented. The PSpice-based model uses bipolar junction transistors and resistors available in the PSpice library. The model includes the phenomena like activation polarization, ohmic polarization and concentration polarization (mass transport effect) present in a PEM fuel cell. The temperature dependence has been included in the model characteristics according to the Nernst equation. Using the parametric modeling the model of a basic fuel cell can be extended to a fuel cell stack. The static characteristics obtained through simulation are compared with some experimental results, given in the literature, obtained on a commercial PEM fuel cell modules.","PeriodicalId":244464,"journal":{"name":"2008 11th International Conference on Optimization of Electrical and Electronic Equipment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2008-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127418445","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}
