A new compound priority control strategy, CPC, is discussed, which takes both the lot release strategy and the scheduling strategy into account. According to the compound priorities of jobs that compete for processing, the CPC strategy can determine which lot(s) is/are processed when the machine is available, and determine when the new lot(s) is/are released into the wafer fab. The CPC strategy can even halt the non-bottleneck machines to prevent overstock of WIP before the bottleneck machines. Simulation results indicate that the CPC strategy has higher performance in reducing the cycle time and its standard deviation, and decreasing the WIP inventory.","PeriodicalId":313251,"journal":{"name":"Proceedings. 2005 IEEE Networking, Sensing and Control, 2005.","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126405764","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}

Such methods often use local surface models or polynomial approximation for a local neighborhood to obtain the subpixel edge location. Whereas their performance are good in smooth area, they are typically poor to deal with singularities presented in discrete data and bring discontinuous edge location. In this paper, we propose an improved level set reconstruction(ILSR) technique to overcome these limitations by locating curves while: 1) obtaining continuous and smooth curve, and 2) keeping edge, especially corner location precision. This is accomplished by ILSR scheme in which curves are smoothed along isophotes with anchor and topology constraints at corners which are guided by corner judgement This method results in subpixel location with accurate edge position.","PeriodicalId":313251,"journal":{"name":"Proceedings. 2005 IEEE Networking, Sensing and Control, 2005.","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121674213","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 order to satisfy the stringent performance requirements of the mission (drag compensation down /spl mu/N and attitude tracking with /spl mu/rad accuracy) with reasonable control robustness, a H/sub /spl infin// technique based on a linear matrix inequalities optimization procedure is implemented.

Recently, texton based texture analysis has been an intensely researched topic especially using Gabor filters output as features for texton construction. The redundancy of Gabor filters makes texton based methods highly time costing. Considering the time cost reducing problem, anisotropic diffusion (AD) filters are introduced in feature extraction for texton construction. Because anisotropic diffusion makes lots of similar features effectively merge together, this method largely reduces feature vectors and time cost on the basis of reliable texton construction. Because of the nonlinearity of nonlinear diffusion, the widely used histogram comparison technique - Earth move distance (EMD) - is not effective for this framework, an appropriate method is proposed instead. Experiments demonstrate the better quality of our method.","PeriodicalId":313251,"journal":{"name":"Proceedings. 2005 IEEE Networking, Sensing and Control, 2005.","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121877327","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 sensor head consists of two fiber Bragg gratings of identical Bragg reflection wavelengths bonded on one giant magnetostrictive rod of Terfenol-D with one grating fixed on both ends and the other grating extensible freely. As the giant magnetostrictive rod lengthens according to an external magnetic field, only the fixed grating is stretched accordingly and the Bragg wavelength shifted to a larger value, while no strain is imposed on the other grating, which resulting in two reflectivity peaks in the dual gratings' reflected spectra. With the help of an optical spectrum analyzer, the difference between the Bragg wavelengths of the two gratings which relates to the applied external magnetic filed is readily measured. Temperature compensation is accommodated partly by the use of the dual fiber Bragg gratings configuration. Experimental results are presented and the properties such as measuring range, linearity, and sensitivity of the sensor design are discussed.","PeriodicalId":313251,"journal":{"name":"Proceedings. 2005 IEEE Networking, Sensing and Control, 2005.","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131989808","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}

It is pointed out that the equivalent transverse load depends on the edge electric field distribution of parallel plate capacitor.
