To overcome the problems, an observer-based constrained model predictive control is presented for controlling the substrate feeding in bioreactor. First, the modified observer is used for obtaining full state information. Next, from the full state information, the controller is implemented using input output linearization method. The proposed controller (OCMPC) is compared with other controllers to show the effectiveness of the proposed controller.

FTA is a system that is suitable for detecting and recovering software error based on pervasive computing environment as RCSM(Reconfigurable Context-Sensitive Middleware) by using software techniques. One of the methods to detect error for session's recovery inspects process database periodically. But this method has a weak point of inspecting all processes without regard to session. Therefore, we propose FTA. This method detects error by inspecting by hooking method. If an error is found, FTA informs GSM of the error. GSM informs Daemon or SA-SMA of the error. Daemon creates SA-SMA and so on.

This paper presents a fast and robust recognition method of noisy code 39 barcode. The proposed method can be divided into two steps: search and decoding. In the first step, all asterisks in the image are found with evenly defined scan lines and then those with the same directions are matched together to get a valid barcode region. In the second step, a local denoise method is first applied to eliminate noise in the barcode region and then a middle band filter is used to decode the barcode. Our method is simple in comparison with former methods and experimental results show that it is efficient for fast barcode recognition on noisy images.","PeriodicalId":133842,"journal":{"name":"16th International Conference on Artificial Reality and Telexistence--Workshops (ICAT'06)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123168942","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}

A \"ring\" shape zone is constructed near isosurface. The bound threshold of the zone is determined by the half length of the cell diagonal. The cells inside the zone are processed, and the cells outside the zone are removed. The fast visualization algorithm is applied to the implicit surfaces represented by radial basis functions and multi-level partition of unity. By utilizing the mathematical properties of these implicit functions, the difficulty of calculating the shortest distance from one space point to the surface is solved. Consequently, a fast algorithm of extracting isosurface is implemented. Experimental results show that the new algorithm speeds up the process of extracting the isosurface.","PeriodicalId":133842,"journal":{"name":"16th International Conference on Artificial Reality and Telexistence--Workshops (ICAT'06)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115076357","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}

Our method starts from classification of input pixels of the input images into two categories, indicating the planar and non-planar surfaces respectively. For the planar surfaces, normal texture-mapping is applied. For the pixels corresponding to the nonplanar surfaces, we propose a method for obtaining some textured planes, called virtual planes, to represent the visual appearance of the nonplanar surfaces. A reconstructed virtual plane is a textured and partially transparent plane into which the input images are mapped using perspective projection. The RANSAC method is used to find the position of the textured planes, and optic flow measures are used to determine their textures. For other pixels corresponding to the non-planar surfaces with rich geometrical details, we use the point primitive to reconstruct the surface, where the redundant pixels are removed again through sampling rate comparison. Under this hybrid reconstruction, polygon texture mapping and point-based rendering are combined to produce the novel views, to take full advantages of the acceleration power of graphics hardware","PeriodicalId":133842,"journal":{"name":"16th International Conference on Artificial Reality and Telexistence--Workshops (ICAT'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129590125","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}
