  1. 1. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jules Reniaud; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. LÄS MER

  3. 2. Energiefektivisering av processluftsuppvärmning till bentonitkvarn i Luleå malmhamn

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Erik Arvidsson; [2022]
    Nyckelord :bentonit; energiefektivisering; batterivärmeväxlare; industri; processluft;

    Sammanfattning : LKAB har en bentonitkvarn i Luleå malmhamn, vars uppgift är att mala samt torka bentonit, vilket är ett hydroflt material. Torkningen utförs genom att värma upp torr uteluft med direktverkande el. Luften passerar bentoniten vid malningen, där fukten extraheras från materialet och binder den i luften. LÄS MER

  4. 3. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Mustafa Kadhim; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.

  5. 4. Development and Construction of a Mechanically Sprung Shock Absorber with Adjustable Spring Stiffness for Mountain Bikes

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Martin Holm; [2021]
    Nyckelord :Adjustable stiffness; coil shock; mountain bike; Justerbar styvhet; fjäderdämpare; terrängcykling;

    Sammanfattning : In this thesis project, the possibility to make use of a mechanical spring to achieve stiffness adjustability in a shock absorber for mountain bikes is evaluated. A mechanical spring increases the shock absorber’s sensitivity compared to a fully adjustable air spring. LÄS MER

  7. 5. Geographical Mapping of the Building Envelope Surface Optimal Optical Properties Minimizing the Energy used to Maintain Indoor Conditions

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Alejandro Rodríguez-Urdaneta; [2020]
    Nyckelord :buildings; energy efficiency; energy savings; energy simulations.; edificios; eficiencia energética; ahorro de energía; simulaciones energéticas.;

    Sammanfattning : Several studies have shown that the buildings envelope optical properties are important in terms of energy use and thermal comfort level. However, no study has been found in regard of the optimal optical properties for the building envelope. LÄS MER
