  2. 1. Solutions and their ambiguities for structure and motion problems

    Author : Magnus Oskarsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

    Abstract : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. READ MORE

  4. 2. Discrete element modelling of the mechanical behaviour of lithium-ion battery electrode layers

    Author : Axel Lundkvist; Per-Lennart Larsson; Pär Jonsén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; mechanical characterisation; simulations; contact mechanics; discrete element method; Litiumjonbatterier; mekanisk karakterisering; simuleringar; kontaktmekanik; diskret elementmetod; Teknisk mekanik; Engineering Mechanics; Solid Mechanics; Hållfasthetslära;

    Abstract : Since their introduction in the late 20th century, lithium-ion batteries have become the leading battery technology for portable devices and electric vehicles due to their high energy density and rechargeability. However, the increasing demand for a longer battery life span is hindered by the fading of the battery’s charge capacity over prolonged use. READ MORE

  5. 3. Light and X-ray scattering investigations of microtubules subjected to oscillating electric fields

    Author : Per Börjesson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microtubules; Electric fields; High-frequency fields;

    Abstract : I vårt dagliga liv blir vi utsatta för oscillerande elektriska fält av olika frekvenser. Dessa fält inkluderar mobiltelefoner, wifi, bluetooth, radar för navigering, radar från bilar, kommunikationssatelliter, samt GPS. READ MORE

  6. 4. Novel strategies for enzyme replacement with gene therapy in models of Parkinson’s disease

    Author : Erik Cederfjäll; Brain Repair and Imaging in Neural Systems (BRAINS); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AAV vectors; dopamine; enzyme replacement; gene regulation; GTP cyclohydrolase 1; L-DOPA; tyrosine hydroxylase; Parkinson’s disease;

    Abstract : Parkinson’s disease is a brain disorder characterized by loss of dopaminergic neurons in the midbrain, resulting in the characteristic motor symptoms: resting tremor, rigidity, akinesia and postural instability. Symptomatic treatment is based on reconstituting the loss of dopamine in the brain, primarily by oral administration of its precursor L-DOPA. READ MORE

  7. 5. Acoustical properties of earplugs

    Author : Per Hiselius; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; acoustic modelling; objective measurement; insertion loss; earplugs; HPE; HPD; hearing protectors; Two-Port; Four-Pole; attenuation; electro acoustics; acoustics;

    Abstract : In this study an experimental setup for measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is applied to earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent on duplicating the human ear. READ MORE
