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

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : 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.

  2. 2. Enabling Hybrid Real Time and Retrospectively Gated Imaging in a Numerical Phantom

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Mineur; [2023]
    Nyckelord :Cardiovascular Magnetic resonance Imaging CMR ; Sector Wise Golden-Angle SWIG ;

    Sammanfattning : Sector-Wise Golden Angle (SWIG) is a novel approach that was developed to address the limitations associated with Golden Angle radial imaging, commonly used for high temporal resolution flow measurements. Golden angle radial imaging is a time-efficient method that effectively reduces motion sensitivity. LÄS MER

  3. 3. Flame retardant treated wood : An investigation into phytic acid and its ability to act as a flame retardant agent

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Mattias Ström; Herman Paulusson; [2023]
    Nyckelord :Flame-retardant; Phytic acid; Wood;

    Sammanfattning : Flame-retardant coatings have been serving their purpose since the romans ruled Europe. These products have been developed through the years, by mixing and synthetizing solutions, which have resulted in effective, although questionable, products due to their impact on the environment and our health.

  4. 4. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    Master-uppsats, KTH/Kemi

    Författare :Arezu Sehati; [2023]
    Nyckelord :Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Sammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER

  5. 5. Collaborative virtual instrument design : Exploring resonance, agency and affordance through a cooperative virtual instrument

    Magister-uppsats, Högskolan Dalarna/Institutionen för kultur och samhälle

    Författare :Paul Joseph Richard Evans; [2023]
    Nyckelord :;

    Sammanfattning : In this paper, through the process of designing and building a collaborative virtual musical instrument I explore users' sense of resonance and agency in relation to technology. With technology’s constant acceleration leaving many feeling alienated, this paper attempts to investigate technology’s potential for creating more meaningful resonant relationships. LÄS MER
