  1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    University essay from Umeå universitet/Institutionen för fysik

    Author : Franz Wikner; [2024]
    Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

  4. 3. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Hashir Zaheer; [2023]
    Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

  5. 4. Characterization of NOx sensor performance under oscillating pressure conditions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Álvaro López Méndez; [2023]
    Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Abstract : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. READ MORE

  6. 5. Biomimicry-driven Design for Sustainable Construction Equipment : Developing an autonomous sensor cleaning system

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik
