  2. 1. Factorized Geometrical Autofocus for Synthetic Aperture Radar Processing

    Author : Jan Torgrimsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Back-Projection; PGA; SAR; UWB; Autofocus; FGA;

    Abstract : Synthetic Aperture Radar (SAR) imagery is a very useful resource for the civilian remote sensingcommunity and for the military. This however presumes that images are focused. There are severalpossible sources for defocusing effects. For airborne SAR, motion measurement errors is the maincause. READ MORE

  5. 3. Fibrinogen and susceptibility to myocardial infarction : role of gene-gene and gene-environment interactions

    Author : Maria Nastase Mannila; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Atherothrombosis; epistasis; fibrinogen; fibrinogen gamma; fibrin clot structure; haplotypes; myocardial infarction; pleiotropy; SNPs;

    Abstract : Fibrinogen, the precursor of fibrin, is a glycoprotein synthesized in the liver and maintained in plasma at concentrations normally ranging between 2-4 g/L. The fibrinogen molecule consists of two sets of three non-identical polypeptide chains, which are encoded by the fibrinogen gamma (FGG), fibrinogen alpha (FGA) and fibrinogen beta (FGB) genes clustered on chromosome 4.

  6. 4. Initiation and early crack growth in VHCF of stainless steels : Experimental and theoretical analysis

    Author : Muhammad Waqas Tofique; Jens Bergstöm; Nils Hallbäck; Thierry Pallin-Luc; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very High Cycle Fatigue; Stainless steel; Ultrasonic fatigue testing; Crack initiation; Crystallographic crack growth; Distributed Dislocation Dipole Technique; Closed cracks; Materialteknik; Materials Engineering;

    Abstract : Mechanical fatigue is a failure phenomenon that occurs due to repeated application of mechanical loads. Very High Cycle Fatigue (VHCF) is considered as the domain of fatigue life greater than 10 million load cycles. READ MORE

  7. 5. Luminescence of Silicon Nanoparticles Synthesized by Ion Implantation

    Author : Thawatchart Chulapakorn; Anders Hallén; Daniel Primetzhofer; Yanwen Zhang; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon nanoparticle; Photoluminescence; Ion beam synthesis; Ion beam analysis; Fysik; Physics;

    Abstract : Silicon nanoparticles (SiNPs) have been shown to display luminescence in the visible range with a peak wavelength depending on the nanoparticle size. This finding is of potential interest for integration of optoelectronic devices in semiconductor technology. READ MORE
