1. 16. Microwave measurement techniques for industrial process monitoring and quality control

   Författare :Johan Nohlert; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; powder; matched filter; fluidised bed; parameter estimation; cavity resonator; signal detection; finite element method; microwave measurement;

   Sammanfattning : Process monitoring and quality control by sensor measurements are essential for the automatisation and optimisation of many industrial manufacturing processes. This thesis is concerned with microwave sensing, which is a measurement modality with potential to improve the in-line sensing capabilities in several industries. LÄS MER

3. 17. Prosthetic Foot Control for Ground Adaptation

   Författare :Wolfgang Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomous systems; kinematical sensors; Foot prosthesis; embedded computing; sensor fusion;

   Sammanfattning : Wearers of prosthetic feet find walking on inclined ground difficult or uncomfortable. A major reason for this is a limitation in ankle motion in existing prostheses. LÄS MER

4. 18. Data Mining and Analysis for Characterizing Paper from On-line Multisensor Measurements

   Författare :Marcus Ejnarsson; Adas Gelzinis; Högskolan i Halmstad; []

   Sammanfattning : The objective of this thesis is to develop a multi-resolution tool for screening paper formation variations, aiming to detect abnormalities in various frequency regions ranging from millimeters to several meters. The abnormalities detected in different frequency regions give an indication for the paper maker about specific disturbances in the paper production process. LÄS MER

5. 19. Efficient parallell architectures for future radar signal processing

   Författare :Anders Åhlander; John L. Gustafson; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer architecture; radar signal processing; space-time adaptive processing; synthetic aperture radar; parallel processing; engineering efficiency; Computer science; Datalogi;

   Sammanfattning : The processing demands on future embedded radar signal processors may stretch to several trillions of floating-point operations per second (TFLOPS). This is an increase of two to three orders of magnitude realtive to the requirements of today. Still, the tight size and power constraints are unchanged. LÄS MER
