  1. 1. Robust Visual Object Tracking mean shift, particle filters and point features

    Författare :Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Sammanfattning : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. LÄS MER

  3. 2. On New Implants - The results of five prospective, randomized RSA trials with aspects on phased introduction and continuous migration

    Författare :Mats Molt; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; New total knee arthroplasty; TKA; RSA; randomized; prospective; prediction; continuously migrating; safety; stability CR; PS; PF; PA; short stem; tourniquet;

    Sammanfattning : A concern that arises with any change in design or operative technique is whether it affects the long-term implant stability or not. One way to address this is, by measuring early micromotion, to predict the future revision rate. LÄS MER

  4. 3. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Författare :Bo Li; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PLIF; LIF; Laser-Induced Fluorescence; Rayleigh scattering; Laser Diagnostics; flame font; Combustion; Turbulence; Photofragmentation LIF; PF-LIF; Laser-induced Phosphorescence; LIP; Fysicumarkivet A:2012:Li;

    Sammanfattning : Nowadays, more than 90% of our energy comes from combustion processes. Hence, it is very important to perform combustion research to reduce emissions, improve efficiency, find clean and renewable fuels, strengthen safety, etc. LÄS MER

  5. 4. On the principles of word formation in Swedish

    Författare :Gunlög Josefsson; Svenska; []
    Nyckelord :HUMANIORA; HUMANITIES; Originator; Force; Telicity; Event measurer; LF-lexicon; PF-lexicon; List of Morphemes; Property; Thing; Event; prefix; major ontological categories; suffix; compound; derivation; linking element; asymmetry; Move; Merge; Generalized Transformations; word class; inflection;

    Sammanfattning : My thesis is an attempt to give a minimalist account of word formation in Swedish. (See Chomsky (1993) and (1994).) In the main part of my thesis I demonstrate how the proposed system accounts for the central aspects of Swedish word formation. LÄS MER

  7. 5. Effects pf hypoxia and antiepileptic drugs of electrophysiological properties of CA1 neurons in hippocampus

    Författare :Marita Englund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antiepileptic drug; brain slice; epilepsy; hippocampus; hypoxia; patchclamp; rat;

    Sammanfattning : This thesis is based on three experimental studies (I-III) of CA1 hippocampal neurons in rat brain slices, where the electrophysiological properties are examined with patch clamp technique under hypoxic conditions and during treatment with antiepileptic drugs, respectively. The cells were visualized and identified in the slice by means of infrared differential interference contrast (IR-DIC) video microscopy and the experiments were carried out at room temperature (22-25 ºC).
