  1. 1. Dynamically Reconfigurable Resource Array

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Muhammad Ali Shami; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DRRA; CGRA; FPGA; VLSI; ASIC; Embedded systems; Coarse grain reconfigurable architecture; reconfigurable computing;

    Sammanfattning : The goals set by the International Technology Roadmap for Semiconductors (ITRS) for the consumer portable category, to be realized by 2020, are 1000X improvement in performance with only 40\% increase in power budget and no increase in design team size. To meet these goals, the challenges facing the VLSI community are gaps in architecture efficacy, design productivity and battery capacity. LÄS MER

    Sammanfattning : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.

  3. 3. Techniques for Efficient Implementation of FIR and Particle Filtering

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Syed Asad Alam; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

    Sammanfattning : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. LÄS MER

  4. 4. Characterization and Optimization of Silicon-strip Detectors for Mammography and Computed Tomography

    Detta är en avhandling från STOCKHOLM : KTH Royal Institute of Technology

    Författare :Han Chen; KTH.; [2016]

    Sammanfattning : The goal in medical x-ray imaging is to obtain the image quality requiredfor a given detection task, while ensuring that the patient dose is kept as lowas reasonably achievable. The two most common strategies for dose reductionare: optimizing incident x-ray beams and utilizing energy informationof transmitted beams with new detector techniques (spectral imaging). LÄS MER

  5. 5. Delta++ Resonance Measurements in a High Multiplicity Environment

    Sammanfattning : The very large multiplicity of charged particles encountered in lead on lead collisions in the WA98 experiment at the CERN SPS provided new experimental challenges. Tracking detectors read out with high granularity were developed to achieve accurate position information in two dimensions, with the aim of reconstructing tracks with a minimum of combinatorial difficulties.
