The principle of this work is based on the locomotion of a snake where subsequent links follow the trace of the head. We developed an algorithm where the APF method provides simple, efficient and effective path planning and the modified SA is applied in order for the robots to recover from a local minima. Modifications to the SA algorithm improve the performance of the algorithm and reduce convergence time. Validation on a three-link snake robot shows that the derived control laws from the combined APF and SA motion planning algorithm can successfully navigate the robot to reach its destination, while avoiding collisions with multiple obstacles and other robots in its path as well as recover from local minima.","PeriodicalId":406358,"journal":{"name":"Proceedings of 2010 IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115395059","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 working principle of these two methods is presented in the article. Both methods have been used for the classification of damage patterns for a benchmark civil structure.

Speech endpoint detection and out-of-vocabulary rejection are the most important part of the speech pre-processing and post-processing respectively. The performance of traditional speech endpoint detection based on short-term energy and zero-crossing rate degrade dramatically in noisy environments. Methods based on frequency-domain need complex computing, and they can not meet embedded systems well. In this paper, we present a new endpoint detection algorithm that is based on statistical theory for isolated-word. The correct endpoint detection rate reaches 97.40% using the method. In this paper one-class support vector machine theory is introduced to solve out-of-vocabulary rejection. Using this algorithm system, true recognition fraction(TRF) is up to 96%, and false recognition fraction(FRF ) is about 95%.","PeriodicalId":406358,"journal":{"name":"Proceedings of 2010 IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114448075","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}

Recently, the anode supported planar SOFC becomes a promising candidate for SOFC commercialization due to its higher power density and lower operation temperature. In the work, SOFC and commercially available coal gasifiers and reformer are modeled in MATLAB. The fuel cell and reformer models are built using electrochemical and reaction kinetics equations with empirical data determined parameters using literature data. The integrated semi-empirical IGFC model and simulation guide the selection of appropriate coal gasifier and reformer for a given SOFC in IGFC application. Tests have been done using two different and representative gasifiers with different syngas to fuel the SOFC, to demonstrate the performance difference and the method for identify the best SOFC, gasifier-reformer match. Simulation results showed good consistency with literature data. The work contributes new integrated coal gasification and SOFC system development for improved energy efficiency and emission reduction.","PeriodicalId":406358,"journal":{"name":"Proceedings of 2010 IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129289238","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 optimal control law can be obtained by given a quadratic performance index. And a modified controller, i.e. PFC plus integrator, is also presented to regulate the effects of disturbances.

It is used for analysis of different biological samples like protein, sirum etc using an array of electrically controlled electrodes. This paper deals with a challenging problem related to the design of DMFB. Specifically the design problem considered is related to high-performance droplet routing, where each droplet has single source location and single target location. The objectives are (i) minimizing the number of electrodes used in the DMFB, and (ii) minimizing total routing time/latest arrival time of all the droplet at their target locations. We propose a simple algorithm for concurrent path allocation to multiple droplets, based on the classical shortest-path algorithm, together with the use of stalling, and possible detouring of droplets in cases of contentions. The algorithm is also extended to droplet routing where a droplet may have two source positions and a single target position. The algorithm is implemented on a Linux platform and empirical results are quite encouraging.","PeriodicalId":406358,"journal":{"name":"Proceedings of 2010 IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125597709","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}
