    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  3. 2. Consequences of Magnetic Properties in Stainless Steel for a High-efficiency Wave Power Generator

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Mohamed Sheikh Abdi; Yosef Gebresilassie; [2018]
    Keywords : stainless steel; wave power; permeability;

    Abstract : A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. READ MORE

  4. 3. Model based design of an expiratory valve and voice-coil actuator and evaluation of complete expiratory system performance with a PI controller

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : MIKKO KIESI; ROBERT AXELSSON SJÖBLOM; [2016]
    Keywords : model based design; mechanical ventilation; voice coil actuator; magnetic circuit; modellbaserad design; mekanisk ventilation; talspole aktuator; magnetisk krets; marginal;

    Abstract : Mechanical ventilators are devices in critical care to assist breathing in case of expiratory dysfunction. The expiratory valve is a critical component to the ventilator as it controls the pressure in the patient’s lungs. READ MORE
