Our proposed system automatically detects the main region of frames captured from a regular camera, analyses the difference in foreground in the main region of consecutive frames to estimate the user's intensity level, then renders virtual scene with appropriate speed. The system does not require any special devices as existing interactive fitness games. Experimental results demonstrate the effectiveness and the realtime manner of the proposed system. Our proposed method can also be applied to develop various exciting interactive games to stimulate excitement for users when doing in-door fitness exercises or to create virtual environment for museums where visitors just stay in place to explore scenes in museums.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129409762","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}

There are some algorithms for generating permutations of a set, e.g. a reverse alphabetical order algorithm, an algorithm based on adjacent transpositions, an algorithm determining permutations from their reductions... But these algorithms are rather long and difficult to parallelize. In this paper we point out that the set of all permutations of a set is isomorphic to the set of their inversion vectors. Thus, we construct a new algorithm determining permutations from their inversion vectors. The algorithm is simpler and shorter than existing ones. Furthermore, this algorithm is easy to parallelize. We parallelize the proposed algorithm by one of two methods. The first one is tasks dividing: 1) finding an inversion vector, and 2) determining a permutation from the just found inversion vector. Two these tasks are performed in parallel with equal computing amounts. The second parallelizing method is based on splitting the sequence of all desirable permutations into subsequences and then concurrently generating the subsequences.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131577421","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}

First, sample data of light-traps are analyzed by the two mentioned methods running on R packages. Second, the results are visualized on the multi-agent system (GAMA) combined with the geographic information system (GIS). As a result, managers can easily survey the density of BPH populations on rice fields to control the damage of BPH more effectively and bring in higher yield for farmers.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134363505","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}

At the time of building the system, on given database, we mine first the lattice of closed itemsets. Based on that lattice, whenever the constraint or the minimum support changes, the lattice of all restricted frequent closed itemsets is obtained. The set of all association rules restricted on constraint partitions into disjoint equivalence classes. Each class is represented by a pair of two nested frequent closed itemsets. Then, we just mine independently each rule class. Users can select the rule class that they are interested in. Spending only a little of time, we can mine and figure out the basic rules of that class. They are useful for users because their left-handed sides are minimal and their right-handed sides are maximal. When necessary, the set of all remaining consequence ones together with their confidences can be quickly generated from the basic ones. This consequence set also splits into the different subsets according to different generating operators. Hence, our approach is very efficient and close to user! The theoretical affirmations and experimental results prove that.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"35 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125721718","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}

Although DTPs are very common in real-world applications, they have received very little attention from the fleld of evolutionary and meta-heuristic optimisation. Due to this lack of research there are still many characteristics that we do not fully know about DTPs. For example, is there any characteristics of DTPs that we do not know; with these characteristics are DTPs still solvable; and what is the appropriate strategy to solve them. In this paper these issues will be partially addressed. First, we will identify a new and challenging class of DTPs where it might not be possible to solve the problems using traditional methods. Second, an approach to solve this class of problems under certain circumstances will be suggested and experiments to verify the hypothesis will be carried out. Two test problems will be proposed to simulate the property of this new class of DTPs, and discussions of real-world applications will be introduced.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127135087","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 advents of recent sequencing technologies allow us to deal with this task efficiently. Amongst these, Support Vector Machine (SVM) has been applied successfully up to more than 80% accuracy in the case of predicting gene regulatory activity in Drosophila embryonic development. In this paper, we introduce a metaheuristic based on genetic algorithm (GA) to select the best parameters for regulatory prediction from transcriptional factor binding profiles. Our approach helps to improve more than 10% accuracy compared to the traditional grid search. The improvements are also significantly supported by biological experimental data. Thus, the proposed method helps boosting not only the prediction performance but also the potentially biological insights.","PeriodicalId":115212,"journal":{"name":"2012 IEEE RIVF International Conference on Computing & Communication Technologies, Research, Innovation, and Vision for the Future","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122407116","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}
