  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; 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.

  3. 3. On the influence of imperfections on microstructure and properties of recycled Al-Si casting alloys

    University dissertation from Jönköping : Jönköping University, School of Engineering

    Author : Anton Bjurenstedt; Högskolan i Jönköping.; Högskolan i Jönköping.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled Al-Si alloys; Fe-rich intermetallics; Melt quality; Fractography; Defekter; Återvunna Al-Si legeringar; Fe-rika intermetaller; Smältakvalité; Fraktografi;

    Abstract : There are great energy savings to be made by recycling aluminium; as little as 5% of the energy needed for primary aluminium production may be required. Striving to produce high quality aluminium castings requires knowledge of microstructural imperfections, which is extra important when casting recycled aluminium that generally contains higher levels of imperfections compared to primary aluminium.

  4. 4. Thermally homogenous gasification of biomass/coal/waste for medium or high calorific value syngas production

    University dissertation from Stockholm : KTH

    Author : Anna Ponzio; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Abstract :  Today’s problems with emissions of green house gases, land filling of waste and depletion of the oil reserves calls for new energy systems based on alternative fuels like biomass and waste. Gasification is an attractive technology for the use of such solid fuels. READ MORE

  5. 5. Energy Efficiency through Thermal Energy Storage Possibilities for the Swedish Building Stock

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Heier; KTH.; Högskolan Dalarna.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Abstract : Behovet av värme och kyla i byggnader utgör en betydande del av ett lands totala energianvändning och att reducera detta behov är av yttersta vikt för att nå nationella samt internationella mål för minskad energianvändning och minskade utsläpp. En viktig väg för att nå dessa mål är att öka andelen förnyelsebar energi för kylning och uppvärmning av byggnader.
