  1. 21. Comparative Study of APFO-3 Solar Cells Using Mono- and Bisadduct Fullerenes as Acceptor

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik, kemi och biologi

    Författare :Yu-Te Hsu; [2010]
    Nyckelord :Polymer solar cell; bisadduct fullerene; photoluminescence quehching;

    Sammanfattning : The urgent need for new, sustainable energy source intrigues scientists to provide the solution by developing new technology. Polymer solar cell appears to be the most promising candidate for its low cost, flexibility, and massive producibility. LÄS MER

  3. 22. Destination Branding and Demand : Formulating Expectations Through Perceptions

    Master-uppsats, Internationella Handelshögskolan

    Författare :Chen-Yu Liu; Jessica Virta; [2010]
    Nyckelord :City branding; Expectations; Experience; Jönköping; Las Vegas;

    Sammanfattning : This paper looks at the perceptions of people within and outside of Jönköping, regard-ing the main attractions/attributes within the Jönköping region and how they are being branded by the municipality. A model was formed to explain how consumer expecta-tions affect demand, and based on that a survey was handed out to find out consumers travelling habits, general perceptions about Jönköping and its branding.

  4. 23. Evaluating and Implementing JPEG XR Optimized for Video Surveillance

    Master-uppsats, Datorteknik

    Författare :Lang Yu; [2010]
    Nyckelord :Video Surveillance; JPEG XR; Encoder; SoC; Evaluation; PSNR; Compression Ratio; Implementation; PCT; Quantization; Adaptive Prediction; Adaptive Entropy Coding;

    Sammanfattning : This report describes both evaluation and implementation of the new coming image compression standard JPEG XR. The intention is to determine if JPEG XR is an appropriate standard for IP based video surveillance purposes. Video surveillance, especially IP based video surveillance, currently has an increasing role in the security market. LÄS MER

  5. 24. Optical Spectroscopy of GaN/Al(Ga)N Quantum Dots Grown by Molecular Beam Epitaxy

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Kuan-Hung Yu; [2009]
    Nyckelord :Quantum dots; GaN; AlN; Exciton; Biexciton; micro-Photoluminescence.;

    Sammanfattning : GaN quantum dots grown by molecular beam epitaxy are examined by micro-photoluminescence. The exciton and biexciton emission are identified successfully by power-dependence measurement. With two different samples, it can be deduced that the linewidth of the peaks is narrower in the thicker deposited layer of GaN. LÄS MER

  7. 25. Enhanced SAR Image Processing Using A Heterogeneous Multiprocessor

    Uppsats för yrkesexamina på grundnivå, Institutionen för datavetenskap

    Författare :YU SHI; [2008]
    Nyckelord :CELL Broadband Engine; Synthetic antenna aperture; Fast Factorized Back Projection FFBP algorithm; C language; parallel programming; parallel computing; Matlab;

    Sammanfattning : Synthetic antenna aperture (SAR) is a pulses focusing airborne radar which can achieve high resolution radar image. A number of image process algorithms have been developed for this kind of radar, but the calculation burden is still heavy. So the image processing of SAR is normally performed “off-line”. LÄS MER
