The first is the arithmetic type based on dual cell representation, expressed by replacing each parameter with a pair of parentheses, the first is the actual value and the second is corresponding fuzzy level, (Value, Fuzzy Level). The second is the visual type based on colored cells representation expressed by replacing each parameter by its value and coded (negative or positive) colors based on the color Hue circle corresponding to its fuzzy level. The quadratic programming problem formulation in its general form is developed in a fully fuzzy environment. A modified dual simplex method algorithm is depicted for the representation of the equivalent linear optimization problem. The problem is represented in a spreadsheet model with built-in programmed Visual Basic Applications macros. The proposed fuzzy logic algebra is then used in a straightforward manner inside this spreadsheet model. The fuzzy logic levels can be easily transferred at the end of the solution to equivalent uncertainties (each level is substituted by a corresponding actual mean and actual standard deviation). Finally, a numerical example is given to illustrate the efficacy of the developed formulations.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134145557","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 system concept is that FSs will sense perimeter intrusions and act as a cueing sensor to an ensemble of robots. These robots in turn engage the potential intruder, performing surveillance and/or neutralization of the intrusion. To minimize the intruder missing rate and response time, some robots have to perform tracking of the intruders while others have to deploy themselves dynamically to cover the protected area. Therefore, a shame-level based dynamic task allocation algorithm is proposed for intruder tracking and allocation, and a gap-based algorithm is proposed for self-deployment of the remaining robots. Both algorithms are developed in a decentralized manner, which means each robot can only communicate with its local neighbors without any global controller unit. Extensive simulation results demonstrate the efficiency and flexibility of the proposed algorithm in a dynamic intruder detection task.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133831914","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 research, signatories' biometric fingerprint in digital binary format as a watermark message will be embedded into a gray level document image by discrete wavelet transform. Experimental results show that the proposed method is quite robust to various attacks such as Gaussian White Noise, JPEG Compression and Low-Pass Filters, and is successfully tested for embedding the fingerprint watermark message and extraction even if the watermarked document image has been attacked by some imitated interferences. In our prototype system, Discrete Wavelet Transform method can be applied to authenticate the genuine against signatories by comparing signatory's fingerprint with the fingerprint watermark message extracted from the archived watermarked document image.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"2019 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114040475","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 ability to package MFC with micron precision is a critical issue. This paper will report on a workcell developed for PMMA MFC alignment with micro assembly operations in volume MEMS devices production. The workcell consists of a 4-DOF (Degree of Freedom) high precision positioning unit, a split-field imaging unit, and an auxiliary unit. Zooming, focusing and illuminating of the optics can be adjusted automatically through image analysis to bring the alignment keys into view with high-level image quality. The work-cell reported in this paper integrates techniques of microscopic computer vision, precise positioning and pneumatic driving technique. With the substrate's external characteristic of “macro to micro” scale, the developed work-cell demonstrates the feasibility of using hybrid macro-manipulation and micromanipulation. Interactions between different units in the system and flexibility of accommodating multi-scale MEMS devices are considered in building the work-cell. Experimental results show that the average operation cycle time is 3.4 minutes; the microassembly accuracy of the system can reach 2.9 microns. The workcell can do micro-alignment assembly tasks efficiently and reliably for industrial applications.","PeriodicalId":223425,"journal":{"name":"2009 International Conference on Information and Automation","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115776640","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}
