    Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE

  3. 3. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Svante Björklund; Blekinge Tekniska Högskola.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; signal processing; array antenna; subarray; clutter; jamming; interference; direction of arrival estimation; security; micro-Doppler; feature extraction; classification;

    Abstract : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. READ MORE

  4. 4. Stereoscopic Label Placement Reducing Distraction and Ambiguity in Visually Cluttered Displays

    University dissertation from Linköping : Linköping University Electroic Press

    Author : Stephen D. Peterson; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Label placement; user interfaces; stereoscopic displays; augmented reality; virtual reality; visual clutter; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : With increasing information density and complexity, computer displays may become visually cluttered, adversely affecting overall usability. Text labels can significantly add to visual clutter in graphical user interfaces, but are generally kept legible through specific label placement algorithms that seek visual separation of labels and other objects in the 2D view plane.

  5. 5. Evolutionary optimisation of a morphological image processor for embedded systems

    University dissertation from Chalmers University of Technology, Dep. of Applied Mechanics

    Author : Andreas Magnusson; Högskolan i Borås.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded system; machine vision; morphological image processing; genetic algorithm; Energi och material; hardware-based genetic algorithm;

    Abstract : The work presented in this thesis concerns the design, development and implementation of two digital components to be used, primarily, in autonomously operating embedded systems, such as mobile robots. The first component is an image coprocessor, for high-speed morphological image processing, and the second is a hardware-based genetic algorithm coprocessor, which provides evolutionary computation functionality for embedded applications.
