  1. 16. Remote Monitoring and Automatic Fall Detection for Elderly People at Home

    Författare :Gregory Koshmak; Maria Linden; Blerim Emruli; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; remote monitoring; aging population; fall detection; Computer Science; datavetenskap;

    Sammanfattning : Aging population is a one of the key problems for the vast majority of so called "more economically developed countries" (MEDC). The amount of elderly people who suffer from multiple disease and require permanent monitoring of their vital parameters has increased recently resulting in extra healthcare costs. LÄS MER

  2. 17. Electrode degradation in proton exchange membrane fuel cells

    Författare :Alejandro Oyarce; Göran Lindbergh; Carina Lagergren; Steven Holdcroft; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PEMFC; PEFC; Porous electrodes; Carbon corrosion; Carbon nanotubes; Carbon fibers; Polyhedral carbon nanofoams; Phosphonated hydrocarbon ionomer; Mass-transport losses; Electrode morphology; Electrode collapse; Start-up and shut-down; System strategies; Stainless steel; Bi-polar plates; In-situ contact resistance.;

    Sammanfattning : The topic of this thesis is the degradation of fuel cell electrodes in proton exchange membrane fuel cells (PEMFCs). In particular, the degradation associated with localized fuel starvation, which is often encountered during start-ups and shut-downs (SUs/SDs) of PEMFCs. At SU/SD, O2 and H2 usually coexist in the anode compartment. LÄS MER

  3. 18. Driving in Virtual Reality : Requirements for automotive research and development

    Författare :Björn Blissing; Johan Ölvander; Fredrik Bruzelius; James Oliver; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual Reality; Augmented Reality; Mixed Reality; Driver Behavior; Active Safety Testing;

    Sammanfattning : In the last decades, there has been a substantial increase in the development of complex active safety systems for automotive vehicles. These systems need to be tested for verification and validation to ensure that the system intervenes in the correct situations using the correct measures. LÄS MER

  4. 19. Adhesive wear testing and modelling of tool steels sliding against sheet metals

    Författare :Fredrik W. Lindvall; Jens Bergström; Pavel Krakhmalev; Mikael Olsson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive wear; Materialteknik; Materials Engineering;

    Sammanfattning : Sheet metal forming is a manufacturing method used because of its versatility. Sheets are plastically deformed by a tool to create a product. A tool is expected to last for several 100,000 forming operations and efforts are made to optimize the tools. A common type of wear referred to as galling is the adhesion of sheet material to the tools. LÄS MER

  5. 20. Diagnosing pneumonia in primary care : Aspects of the value of clinical and laboratory findings and the use of chest X-ray

    Författare :Anna Moberg; Magnus Falk; Jakob Paues; Sven Göran Fransson; Ronny Gunnarsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It is important to identify patients with pneumonia because it is potentially a serious disease, often of bacterial origin, that should be treated with antibiotics. It is equally important to identify those with acute bronchitis, a self-limiting disease, that should not be treated with antibiotics. LÄS MER
