A faster, simpler, and accurate algorithm based on Transfer Matrix method has been introduced for solving time independent Schrödinger equation in the most general case of aperiodic and asymmetric MQW structure. The MQWs are aperiodic with varying well and barrier widths and asymmetric i.e., having different materials and effective masses for the different regions of the wells and barriers. Adjacent wells are coupled through the barriers. Effect of barrier width on the tunneling properties has also been investigated. The theoretical results are compared with experimental results of Giorgetta et all [1]. Results of the computation based on the general model agree well with experimental data.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123790420","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 decimation filters work two fold, they decimate the sampling rate by a factor of OSR[over sampling rate] in doing so they remove the outband quantization noise resulting in an increase in resolution The speed, area and power consumption of oversampled converter are governed largely by decimation filters in sigma-delta A/D converters. The paper presents a design and implementation of a sigma-delta digital decimation filter. The decimation filter structure is based on cascaded-integrated Comb(CIC) filter[1].

This talk will describe research at Los Alamos National Laboratory and at the University of New Mexico on optical refrigeration and on thin-film electrocaloric heat engines. In optical refrigeration, the goal is to cool solids, typically rare-earth doped glasses and crystals or direct-band-gap semiconductors, to cryogenic temperatures by anti-Stokes luminescence. The best result so far is the cooling of a Yb:YLF crystal to 155 K from room temperature. Thin-film heat engines use a layer of electrocaloric material sandwiched between two thin-film heat switches to provide near-room-temperature cooling or to extract electrical power from heat flows. With heat switches based on liquid crystals, thin-film heat engines should be competitive with thermoelectric devices. With more effective heat switches, thin-film heat engines may rival vapor compression devices.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124226490","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 the conventional method, interpretation of the large number of radiographs for defect detection and evaluation is carried out manually by operator or expert, which makes the system subjective. Also interpretation of large number of images is tedious and may lead to misinterpretation. Automation of Non-Destructive evaluation techniques is gaining greater relevance but automatic analysis of X-Ray images is still a complex problem, as the images are noisy, low contrast with a number of artifacts. ANN's are systems which can be trained to analyze input data based on conditions provided to derive required output. This makes the system automatic reducing the subjective interference in analysis of data. Artificial neural network based systems are thus a feasible solution to this problem of X-Ray NDT. Due to complex nature of input images and noise present, Noise removal becomes a problem in X-Ray images. Preprocessing techniques based on statistical analysis have shown improvement in image noise reduction. Pixels/group of pixels, which deviate from the general structural pattern and grey scale distribution are located. The statistically processed pixel values are used to obtain the features vector from defective as well as from non-defective areas. Software for pre-processing and analyzing NDT images has been developed. Software allows user to train neural networks for defect detection. Once trained satisfactorily, the software scans the new input image and uses the trained ANN for defect detection. The final image with defect regions marked will be displayed. This system can be used to obtain the probable defective areas in a given input image. This paper presents performance of MLP and RBF for detection of defect. The effect of different types of input viz. template and moments on performance of ANN is discussed.","PeriodicalId":149384,"journal":{"name":"2009 International Conference on Emerging Trends in Electronic and Photonic Devices & Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134339763","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}
