  1. 21. Fatigue strength assessment of post weld improved welded joints

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Veronika Nerbe; [2023]
    Keywords : Mechanics; solid mechanics; lightweight structures; hfmi; weld; Mekanik; hållfasthetslära; lättkonstruktioner; hfmi; svets;

    Abstract : In this thesis work a literature survey is done to collect published data for T-welded joints with a thickness of 5-12 mm, produced in high strength steel and treated with HFMI. In addition to this, large structures are researched. READ MORE

  3. 22. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Klas Junskog; [2023]
    Keywords : oscillators; mm-wave; radar; Technology and Engineering;

    Abstract : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. READ MORE

  4. 23. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Natachai Terawatsakul; [2023]
    Keywords : ;

    Abstract : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. READ MORE

  5. 24. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    University essay from KTH/Materialvetenskap

    Author : Christopher Hallén; Marcus Johansson Storne; [2023]
    Keywords : ;

    Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

  6. 25. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

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

    Author : Diogo Antunes; [2023]
    Keywords : Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Abstract : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.
