  1. 1. Ground Object Recognition using Laser Radar Data : Geometric Fitting, Performance Analysis, and Applications

    Författare :Christna Grönwall; Fredrik Gustafsson; Kalle Åström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser radar; object detection; object recognition; performance; least squares; ICP; Cramér-Rao; Signal processing; Signalbehandling;

    Sammanfattning : This thesis concerns detection and recognition of ground object using data from laser radar systems. Typical ground objects are vehicles and land mines. For these objects, the orientation and articulation are unknown. The objects are placed in natural or urban areas where the background is unstructured and complex. LÄS MER

  4. 3. Modeling and Control of Voltage Source Converters Connected to the Grid

    Författare :Michael Lindgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage source converter; switching frequency; pulse width modulation; IGBT valve; power electronics; small-signal; L-filter; LCL-filter; transfer function; line filter; active filtering; frequency response; sampling frequency;

    Sammanfattning : This thesis deals with the modeling and control of pulse width modulated (PWM) voltage source converters connected to the grid. When voltage source converters are connected to the grid, the power quality and the dynamic performance are affected by the line filter connected between the converter and the grid, and by nonlinearities caused by the switching converter.

  5. 4. Data Access Techniques for Enhanced Energy Efficiency and Performance in In-order Pipelines

    Författare :Alen Bardizbanyan; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Cache; Pipeline; Energy Efficiency; Data Access; Performance;

    Sammanfattning : Energy efficiency is one of the key metrics in the design of a widerange of processor types. For example, battery powered devices, whichare growing in numbers every day, require energy efficient processorsto be able to operate for a useful period of time. LÄS MER

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

    Författare :Marie Ström; Chalmers tekniska högskola; []
    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
