  2. 11. Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture

    Author : Andreas Persson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatially distributed hydrological modelling; Precision Agriculture; Yield mapping; Topographical wetness index; Drainage area; Lantbrukshydrologi; marklära; agricultural hydrology; Soil Science;

    Abstract : The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. READ MORE

  4. 12. Xylan sorption kinetics at industrial conditions

    Author : Espen Ribe; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sorption; Yield; Sorption conditions; Kinetics; Kraft cooking; Hemicellulose; Modelling; Black liquor; Xylan;

    Abstract : The kraft process is the most utilised method for the production of wood based chemical pulp for paper applications. During a kraft cook about half of the wood material is dissoluted into the cooking liquor making the liberation of individual fibres possible. This low yield is a great disadvantage for process economy. READ MORE

  5. 13. On the use of periodic operation for improvning chemical processes

    Author : Lennart Vamling; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; periodic operation; di-; ammonia; and triethanolamine production; ethylene oxide; zeolites; Mono-; yield; adiabatic packed-bed reactor; selectivity;

    Abstract : In this thesis, some methods of improving the product distribution from chemical processes are compared. The first two parts contain an experimental investigation of how the product distribution of a process is influenced by the choice of catalyst. READ MORE

  6. 14. Torque and Angle Controlled Tightening of Bolted Joints

    Author : Göran Toth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torque controlled tightening; deformation parameters; momentary elongation; deformation factor; torque; Bolted screwed joints; spring characteristic; Torx; torque and angle controlled tightening; hexalobular; final torque; snug torque; Taylor’s series expansions; preload; plastic deformation; permanent elongation; yield; friction diameter; plastic spring constant; clevis; turn-of-nut method; bearing surface pressure; twisting; Monte-Carlo simulations;

    Abstract : Reduced weight and fuel consumption, improved reliability and engine performance are the main requirements in the automotive industry of today. These requirements demand robust and optimized bolted joints, where a high amount of preload obtained by effective utilisation of the bolt is essential. READ MORE

  7. 15. The Influence of Salting Procedures on the Characteristics of Heavy Salted Cod

    Author : Kristin Thorainsdottir; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; protein; water holding capacity; water; yield; Salting; protein denaturation; cod;

    Abstract : The production of heavy salted cod (bacalao) has changed from being a single-step process salting to a multistep procedure. The aim of this study was to gain a deeper understanding of water retention and yields of heavy salted cod as influenced by salting procedures. READ MORE
