It consists of half-bridge rectifier and two-leg (B4) inverter and is designed for low-power induction machine (IM) drive application. Effect of voltage imbalance between split capacitor bank is discussed and improved control algorithm is proposed to minimize imbalance and compensate its impact on output power quality. Proposed method is verified experimentally with 3 kW model.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132362359","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}

For this purpose our research group has developed an automated high-content online measurement system for living cells. The system is comprised of a pipetting robot, sensors for measurement of pH, pO2, electric signals and cell adhesion, a digital microscope and a climate chamber. The robot is used for media supply, while the sensors monitor the metabolic and morphological parameters of the cells. Reflected light and fluorescence imaging during the course of an experiment are possible due to the included microscope. Sensors are integrated in a special 24-well micro plate that is placed at a fixed position within the system. Oxygen and pH values are usually measured every 5 to 15 seconds. Experiments over a long period of time (several days) are possible, making the system suitable for applications like pharmaceutical drug screening, in vitro chemosensitivity assays, toxicological studies and analytical histopathology.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127604483","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}

However, efficient model processing techniques are required, unless we use models only for documentation purposes. One way to improve efficiency is to apply model transformations in parallel. This paper introduces a truly parallel model transformation framework focusing on a new pattern matching approach. By using this new approach, the framework is now scalable and much more efficient than any parallel model transformation approach before.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132713435","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}

This kernel function is itself a support vector machine classifier that is learned statistically from data. We show that the new kernel manages to change the classical methodology of defining a feature vector for each pattern. One will only need to define features representing the similarity between two patterns allowing many details to be captured in a concise way. The new proposed kernel shows very promising results. It opens the door for new feature definitions that could be created in various machine learning problems where similarity between patterns can be formulated more suitably.","PeriodicalId":256285,"journal":{"name":"IEEE EUROCON 2009","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114301414","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}
