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

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

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

    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.

  4. 4. Thermodynamic and Kinetic Investigation of the Fe-Cr-Ni System Driven by Engineering Applications

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

    Author : Wei Xiong; Malin Selleby; John Ågren; Byeong-Joo Lee; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase transformation; magnetism; spinodal decomposition; stainless steel; low temperature CALPHAD; phase field; ab initio; atom probe tomography; calorimetry; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ; SRA - Energy; SRA - Energi;

    Abstract : This work is a thermodynamic and kinetic study of the Fe-Cr-Ni system as the core of stainless steels. The Fe-Cr, Fe-Ni and Cr-Ni systems were studied intensively using both computational and experimental techniques, including CALPHAD (CALculation of PHAse Diagrams), phase field simulation, ab initio modeling, calorimetry, and atom probe tomography.

  5. 5. Biogas Production from Citrus Wastes and Chicken Feather Pretreatment and Co-digestion

    University dissertation from Chalmers University of Technology

    Author : Gergely Forgács; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pretreatments; co-digestion; economic analyses; citrus wastes; feather; Energi; material; Resursåtervinning; Resource Recovery;

    Abstract : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.
