2. 1. Metamathematical fixed points

   Author : Rasmus Blanck; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; arithmetised metamathematics; fixed point; recursion theory;

   Abstract : This thesis concerns the concept of metamathematical fixed points. After an introduction, we survey the field of metamathematics, from la fin du siècle to present. We are especially interested in the notion of fixed points, theorems on the existence of various kinds of fixed points, and their applications to metamathematics. READ MORE

6. 4. Modelling of biofuel combustion in fixed beds

   Author : Robert Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; packed bed; fixed bed; biofuel; combustion; modelling;

   Abstract : Fixed bed combustion is common is small to medium scale heat production in grate furnaces and domestic boilers. Modelling of these fuel beds can give a better understanding of the conversion process inside them, and provide a tool for analyzing the performance of furnaces and problems related to the fuel bed.

7. 5. Detecting, Modelling and Measuring Disturbances in Fixed-bed Combustion

   Author : Sven Hermansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD modelling; solid fuels; grate furnaces; moisture content; fixed bed; combustion;

   Abstract : Combustion of fixed fuel beds in grate furnaces is one of the most common techniques within production of heat and power from solid fuels. The grate furnace used to be a working horse for combustion of hard coal, while today the incitement of using renewable fuel sources has turned biomass and municipal waste into dominating fuel types.
