In general, for these types of processes, Smith Predictor control schemes are frequently used, however they exhibit poor robustness due to the explicit use of the process model in the compensation loop and require additional control techniques to enhance robustness against modeling uncertainties. An alternative solution used in this paper is a predictive controller, with intrinsic time delay compensation. The simulations presented show that the predictive controller is also robust to significant time delay estimation errors, without further need to design additional filters for increasing robustness.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129525471","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 first one operates time-continuously and is implemented using a LM 13700 operational transconductance amplifier (OTA). Under PSpice simulation and experimentally gathered data the antireciprocity of this gyrator has been verified. The main advantage of this realization is that the energy flow from one port to the other can be simply controlled by modifying the bias currents of the OTAs. The second type is a commutation-operated double-bridge DC-DC converter. The energy flow in this case can be easily controlled by modifying the switching delay of between the bridges.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"324 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116122412","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}

Multicore architectures are built from superscalar and multithreaded processors. Integrating new technologies in embedded applications requires the development of multicore processors that can be integrated into a smaller area like a classic microcontroller. These processors must manage fewer resources and be able to manage multiple tasks simultaneously. In this paper we present a method of modeling, simulation and evaluation of two multithreaded architectures with limited resources, which could be integrated into embedded systems: Interleaved multithreading (IMT) and Blocked multithreading (BMT). Both techniques permit the processing of multiple independent threads, concurrently. In this paper we propose a SimpleScalar Interleaved Multithreading architecture (SS-IMT) and a SimpleScalar Blocked Multithreading architecture (SS-BMT) that are derived from SimpleScalar simulator. We will evaluate the performances of these architectures compared to the performance of standard SimpleScalar architecture.","PeriodicalId":334381,"journal":{"name":"2011 6th IEEE International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134211957","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 authors of this paper joined to these efforts and revised their former results in virtual classroom definition for computer modeling of higher education programs. They recognized new demands and trends in the problem solving centered higher education for engineering and outlined a new concept for entities and their connections in a new computer defined course description.
