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

   Author : Andreas Magnusson; Högskolan i Borås; []
   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;

   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.

   Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

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

   Author : Anna Ponzio; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; 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
