At the same time, engineering has been extended to the entire lifecycle of products. Finally, physical prototyping is being replaced by integrated simulations where this is possible. The above new trends require re-evaluation of teaching engineers. This paper gives a practice oriented outline of a concept for virtual classroom changed to fulfill the above demands. In the centre of discussion, higher importance of virtual classrooms in the near future is emphasized including higher level of integration with professional engineering systems As a main step towards virtual courses on the basis of strong information technology background, a more organized data structure than the currently applied is demanded. The authors of this paper are engaged with analysis in practical application of these descriptions for enhanced computer support in higher education. In this paper, they introduce some basic concepts for advanced modeling of interrelated classroom objects. One of the most important concerns towards a better organized course description is definition of organized activities for course handling systems. The authors analyzed the definition and application organizing activities for the control of course definition and course program execution processes. Following this, typical processes including sequences of typical activities in the course of teaching and learning in the virtual classroom environment are introduced. Finally, a possible integrated implementation of course modeling is outlined for the support of education in engineering.","PeriodicalId":118326,"journal":{"name":"2010 IEEE 14th International Conference on Intelligent Engineering Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123193776","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 this paper author shows that measurement and signal processing problems of now-a-days open new dimensions for the interpretation of the basic concepts of measurement and signal processing and make the reevaluation of these concepts necessary. Traditional methods fail in many cases to yield useful solutions, especially when measurement and signal processing problems reveal considerable complexity, involve a wide spectrum of various disciplines, and require a multitude of components and methods.

This causes by high communication traffic between devices, ressource load, several functionalities, memory usage, execution time, type of architecture, topology, device count or energy consumption. Keeping this factors in mind a special problem is which functionality should be processed on which device (mapping functions to architectures). Optimal system design results in a huge design space, because of a lot of system variants. A model based virtual prototype describes a system on abstract level of detail, enabling analysis and simulation in early design steps to improve or correct the system design. Added optimization algorithms can solve the np-complete mapping problem by creating and estimating new system variants. This combination of performance estimation and design space exploration results in a reconfigured optimized system. The paper shows an approach, that explains the steps from abstract system description via simulation to optimization. Tabu search, simulated annealing and greedy algorithm variants reconfigure the initial system. A theoretical example clarifies the methodology.","PeriodicalId":118326,"journal":{"name":"2010 IEEE 14th International Conference on Intelligent Engineering Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126974923","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 analysis will be performed on combinational logic networks at the gate level. Here single and multiple stuck-at logic faults will be considered. As a result, it is pointed out that the composite justification requires significantly less computational step than the D-algorithm and its modifications. From this fact it has been concluded that possibly no other algorithm is available in this field with fewer computational steps. If it holds, then it follows directly that the test calculation problem is of exponential-time, and so are any other NP-complete problems.","PeriodicalId":118326,"journal":{"name":"2010 IEEE 14th International Conference on Intelligent Engineering Systems","volume":"494 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127028760","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 main advantage of the TP model transformation is that it is executable in a straightforward way and the Linear Matrix Inequality (LMI) based control design frameworks can immediately be applied to the resulting polytopic models to yield controllers with tractable and guaranteed performance. The main contribution of this paper is that it represents the friction of a DC servo drive in TP model form, automatically designs LMI based controller for friction compensation. The reference signal compensation is also based on the TP model transformation. The results were simulated for speed control of the DC servo drive and were compared to other control techniques.","PeriodicalId":118326,"journal":{"name":"2010 IEEE 14th International Conference on Intelligent Engineering Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129425876","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}
