  1. 21. A Hybrid Pixel Detector ASIC with Energy Binning for Real-Time, Spectroscopic Dose Measurements

    Författare :Winnie Wong; Christer Fröjdh; Roberto Dinapoli; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid pixel detector; low power readout chip; photon counting; time over threshold ToT ; energy binning; active personal dosimeter APD ;

    Sammanfattning : Hybrid pixel detectors have been demonstrated to provide excellent quality detection of ionising photon radiation, particularly in X-ray imaging. Recently, there has been interest in developing a hybrid pixel detector specifically for photon dosimetry. LÄS MER

  3. 22. Improved Algorithms for Fast Shading and Lighting

    Författare :Anders Hast; Ewert Bengtsson; Jos Stam; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Graphics; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : Shading is a technique that is used in computer graphics to make faceted objects appear smooth and more realistic. In the research presented in this thesis we have investigated how shading can be generated as efficiently as possible without sacrificing quality. LÄS MER

  4. 23. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor

    Författare :Mikael Antelius; Göran Stemme; Yogesh B. Gianchandani; KTH; []
    Nyckelord :Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; packaging; vacuum packaging; liquid encapsulation; integration; wire bonding; grating coupler; waveguide; Fabry-Perot resonator;

    Sammanfattning : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. LÄS MER

  5. 24. Numerical and Experimental study of shock boundary layer interaction in unsteady transonic flow

    Författare :Olivier Bron; KTH; []
    Nyckelord :Shock Boundary Layer Interaction; Shock Motion; Unsteady Flows; Nozzle Flows; Potential Interaction; Back Pressure Perturbations;

    Sammanfattning : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. LÄS MER

  7. 25. Design, implementation and evaluation of a distributed mediator system for data integration

    Författare :Vanja Josifovski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : An important factor of the strength of a modern enterprise is its capability to effectively store and process information. As a legacy of the mainframe computing trend in recent decades, large enterprises often have many isolated data repositories used only within portions of the organization. LÄS MER
