One of the major challenges of this technique is the image processing phase. The accuracy of this phase has an important impact on the accuracy and effectiveness of the subsequent gene expression and identification analysis. The processing can be organized mainly into four steps: gridding, spot isolation, segmentation, and quantification. Although several commercial software packages are now available, microarray image analysis still requires some intervention by the user, and thus a certain level of image processing expertise. This paper describes and compares four techniques that perform automatic gridding and spot isolation. The proposed techniques are based on template matching technique, standard deviation, sum, and derivative of these profiles. Experimental results show that the accuracy of the derivative of the sum profile is highly accurate compared to other techniques for good and poor quality microarray images.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130865891","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 general, more emphasis is given to protein sequence alignment, and the alignment methods designed for protein sequences can usually be used with little modification for DNA sequences as well. However, it is desirable to design methods specifically for DNA alignments, making use of specific DNA sequence models and if possible, also of the specific sequences being aligned. In this paper, we present an iterative method for DNA sequence alignment with sequence specific transition-transversion ratio. Preliminary experiments indicate that the proposed technique has significant potential. The approach better suits to the nature of the specific DNA sequence pair, and could be a significant step in the direction of using sequence specific substitution matrices for DNA sequences.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121143677","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 paper Constraint Satisfaction Problem (CSP) for smart textiles is defined. The goal is an optimized fault tolerant on-body sensor network. A novel event-driven architecture for smart textiles is proposed. A correlation between the architecture and the design features is established for optimized signal collection, fault tolerance and simplified interconnects. As part of the reliability analysis, this work proceeds to present the description of faults. Then a suitable fault model is defined supporting the defect distribution. Finally, the simulator based on Mealy machines was designed to correlate all the features defined during the course of work.

In the new segmentation scheme, the segmentation points of the reference/master signature are allocated at the minimum velocity points or ldquovalleysrdquo. To avoid an excessive number of segmentation points, a constraint factor of minimum segment size is applied while extracting the valleys. Then, the correspondent segmentation points in each of the test or other enrollment signatures are allocated by finding the minimum velocity points occurring within a window of points centered at each segment-boundary-point of the master signature. The paper also presents an algorithm to select the master/reference signature sample among the enrollment signature samples for each writer. According to the selection criteria, the master/reference signature is the signature that contains the most repeated valleys locations. The evaluation of the new segmentation method showed significant improvement over a benchmark method, developed in earlier work, whose segmentation was based on the dynamic time warping technique.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132101726","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}

Due to the energy loss in the absorptive layers, the photon cannot pass through these barriers with 100% transmission as its electron counterpart. However, it is showed that some peaks appear in the transmission spectrum due to the coherent interference. It is also found that for one kind of transmission peaks, their optical fields form a standing wave pattern along the propagation direction that minimizes the optical loss. The possibility to apply this phenomenon in the optical filter and amplifier design is discussed.","PeriodicalId":215400,"journal":{"name":"2008 IEEE International Conference on Electro/Information Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132994706","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}

We assume that nodespsila axis orientations are unknown. Therefore, all AoA measurements are employed to calculate the angle differences of two different nodes viewed by the third one. Distance measurements between two nodes within the communication range are also utilized in the first method. For the second method, only AoA information is required. As all distance and angle measurements are accurate enough, the localization problem can be formulated as a linear program (LP). Otherwise, by introducing auxiliary variables, it can be cast as a quadratic program (QP).
