    Sammanfattning : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. LÄS MER

  3. 2. School-based Interventions or Prevention Programs regarding Alcohol, Smoking and Drug Use among Adolescents with Disabilities or Physical Impairments : A Systematic Literature Review

    Magister-uppsats, Högskolan i Jönköping/Högskolan för lärande och kommunikation

    Författare :Marouso Triantafyllou; [2019]
    Nyckelord :school-based interventions; prevention programs; adolescents; alcohol consumption; smoking; drug use; physical impairments; disability;

    Sammanfattning : Introduction Substance use in adolescents with disabilities is rising, containing the prevalence of substance-related disorders (SRD) such as addiction, mental or health disorders, cancer, accidents and mortality. Yet little is known about the existing substance use prevention programs among adolescents with dosabilities or physical impairments. LÄS MER

  4. 3. Electrical Pulsing of a Laser Diode for Usage in Fluorescence Microscopy

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Karin Jerner; [2017]
    Nyckelord :electrical pulsing; laser pulsing; fluorescence microscope; laser diode;

    Sammanfattning : A relatively new application for the laser is in fluorescence microscopes. The fluo- rescence microscope needs a high power light source input. Using a laser source improves the precision of the microscope. A pulsed laser source enhances the performance of the fluorescence microscope and a laser diode can be overdriven without being damaged.
