  1. 1. Optimization and Physical Bounds for Passive and Non-passive Systems

    Författare :Yevhen Ivanenko; Sven Nordebo; Börje Nilsson; Mats Gustafsson; Mariana Dalarsson; Aaron Welters; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; physical bounds; Herglotz functions; quasi-Herglotz functions; passive systems; non-passive systems; approximation; absorption in lossy media; Waves; Signals and Systems; Vågor; signaler och system;

    Sammanfattning : Physical bounds in electromagnetic field theory have been of interest for more than a decade. Considering electromagnetic structures from the system theory perspective, as systems satisfying linearity, time-invariance, causality and passivity, it is possible to characterize their transfer functions via Herglotz functions.

  3. 2. Industrial System Level Test Automation

    Författare :Daniel Flemström; Wasif Afzal; Eduard Paul Enoiu; Sundmark Daniel; Andy Zaidman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Vehicular software systems control and monitor many safety-critical functions, such as automated emergency brakes and anti-spin. These functions are integrated and tested at system level to ensure that the entire system works as intended.Traditionally, these functions or selected combinations of functions are tested in isolation.

  4. 3. Development of a Passive Immunization Strategy Against Atherosclerosis

    Författare :Alexandru Schiopu; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; regression; plaque; peptide; oxidized LDL; immune system; carotid stenosis; cardiovascular diseases; apolipoprotein B-100; atherosclerosis; Kardiovaskulära systemet; Cardiovascular system; vascular injury; ultrasound; antibodies;

    Sammanfattning : Atherosclerosis is a chronic inflammatory disease, characterized by the accumulation of lipids and fibrous tissue in the wall of medium and large-sized arteries. The characteristic culprit of the disease is the atheroma, or atherosclerotic plaque, a patchy thickening of the arterial wall which affects the lumen, inducing various degrees of stenosis. LÄS MER

  7. 5. A Passive Sampling System for Monitoring Metals in the Aquatic Environment

    Författare :Lena B Blom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal diffusion; metal monitoring; metal speciation; aquatic systems; passive sampling system;

    Sammanfattning : Water monitoring is undertaken routinely as a requirement of water quality legislation. It is usual that water monitoring is undertaken through spot sampling. A passive sampling system has been developed for the aquatic environment that provides time-averaged (integrated) concentrations for metals. LÄS MER
