  1. 31. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications

    University essay from KTH/Kraft- och värmeteknologi

    Author : Yifeng Zhong; [2022]
    Keywords : maritime transportation; FEMFC; lifetime simulation; degradation mechanism; empirical relationship; semi-empirical approach; sjötransport; PEM-bränsleceller; livslängdssimulering; nedbrytningsmekanism; empiriskt samband; semi-empiriskt tillvägagångssätt;

    Abstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE

  2. 32. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mazen Bahy; [2022]
    Keywords : Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Abstract : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. READ MORE

  3. 33. MICRO-ROS FOR MOBILE ROBOTICS SYSTEMS

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Peter Nguyen; [2022]
    Keywords : ROS; microcontrollers; tracing; mobile robotics; analysis;

    Abstract : The complexity of mobile robots increases as more parts are added to the system. Introducing microcontrollers into a mobile robot abstracts and modularises the system architecture, creating a demand for seamless microcontroller integration. READ MORE

  4. 34. Oil Autonomy of a Turbojet

    University essay from KTH/Flygdynamik

    Author : Florian Steiner; [2022]
    Keywords : Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

    Abstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE

  5. 35. Information Flow and Local Observables in Many Body Localized Systems

    University essay from KTH/Fysik

    Author : Daniel Niemi; [2022]
    Keywords : Theoretical physics; many body localization; localization; aubry-andré; aubry-andrei; condensed matter; quantum matter; Teroretisk fysik; mångpartikellokalisering; lokalisering; aubry-andré; aubry-andrei; kondenserad materia; kvantmateria;

    Abstract : Disordered quantum many-body systems exhibiting the many-body localization (MBL) phenomenon evade the fate of thermalization due to the existence of an extensively large set of quasi-local integrals of motion (l-bits). Due to the size of the Hilbert space of many-body systems, it is hard to compute the time evolution of many-body systems generally, which hinders our understanding of the MBL phenomenon. READ MORE
