    Sammanfattning : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. LÄS MER

  3. 3. Loop detection and extended target tracking using laser data

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Karl Granström; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In the past two decades, robotics and autonomous vehicles have received ever increasing research attention. For an autonomous robot to function fully autonomously alongside humans, it must be able to solve the same tasks as humans do, and it must be able to sense the surrounding environment. LÄS MER

  4. 4. Retroviral long Terminal Repeats; Structure, Detection and Phylogeny

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Farid Benachenhou; Uppsala universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retrovirus; long terminal repeats; hidden Markov models; phylogeny; alignment; conserved motif; stem-loop; MEDICINE Microbiology; immunology; infectious diseases Microbiology Clinical virology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi Klinisk virologi; Klinisk virologi; Clinical Virology;

    Sammanfattning : Long terminal repeats (LTRs) are non-coding repeats flanking the protein-coding genes of LTR retrotransposons. The variability of LTRs poses a challenge in studying them. Hidden Markov models (HMMs), probabilistic models widely used in pattern recognition, are useful in dealing with this variability. LÄS MER

  5. 5. Waveform and Receiver Filter Selection for Wideband Radar Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marie Ström; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interference suppression.; detection; waveform design; receiver filter design; Wideband radar; performance evaluation;

    Sammanfattning : This thesis concerns the design of transmitter-receiver chains for widebandradar systems. The transmitter side employs one, or several, highly flexiblesignal generators, which are able to generate signals with a large bandwidth. LÄS MER
