    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.

  4. 4. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

    Detta är en avhandling från Chalmers University of Technology

    Författare :Faisal Altaf; Chalmers tekniska högskola.; Chalmers University of Technology.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modular batteries; SOC balancing; thermal balancing; battery control; converters; model predictive control; convex optimization; electrified vehicles.;

    Sammanfattning : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. LÄS MER

  5. 5. Advanced X-ray Detectors for Industrial and Environmental Applications

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Salim Reza; Mittuniversitetet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The new generation of X-ray free electron laser sources arecapable of producing light beams with billion times higherpeak brilliance than that of the best conventional X-ray sources.This advancement motivates the scientific community to pushforward the detector technology to its limit, in order to de-sign photon detectors which can cope with the extreme fluxgenerated by the free electron laser sources.
