  1. 1. On Performance of Digital Radio Receiver in Non-Gaussian Interference

    Författare :Kia Wiklundh; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bandwidth conversion; performance estimation; APD; interference; minimum shift keying; man-made noise; Gaussian approximation; measurement; emission requirements; non-Gaussian interference; micro-wave oven; MSK; amplitude probability distribution; emission;

    Sammanfattning : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. LÄS MER

  4. 3. III-V Nanowire-based Infrared Photodetectors : Design, Fabrication and Characterization

    Författare :Vishal Jain; Fasta tillståndets fysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanowire; infrared; photodetector; APD; thermal imaging; telecommunication; fabrication; InP; InAsP; Fysicumarkivet A:2016:Jain;

    Sammanfattning : Semiconductors are the backbone of almost every electrical or optical component, one of them being photodetectors. Photodetectors are used in many applications such as digital cameras or solar panels. They can also be designed to detect the omnipresent infrared radiation, discovered in 1800, which is invisible to human eye. LÄS MER

  5. 4. 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

  7. 5. Analysis of Transvascular Transport Phenomena in the glomerular and peritoneal microcirculation

    Författare :CARL ÖBERG; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peritoneal dialysis; glomerular filtration barrier; pore model; automated peritoneal dialysis APD ; three-pore model;

    Sammanfattning : The current work is devoted entirely to the study of passive transport phenomena, or more specifically, the more simple diffusion, electric migration and filtration of solute matter and water over glomerular and peritoneal capillary walls. The driving forces behind such trans-capillary transport phenomena have long been assumed to be simple gradients of concentration, hydrostatic pressure and electric potential. LÄS MER
