  1. 6. Transport of Mercury Species in the Environment. Exchange between Oceanic Waters and the Atmosphere

    Author : Maria Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mercury; dissolved gaseous mercury; elemental mercury; evasion; flux; Mediterranean Sea; North Atlantic Ocean; Arctic Ocean; accumulation; in-situ measurements; on-line measurements;

    Abstract : Mercury is an element present in the earth crust as well as a component in the atmosphere. During centuries mercury has been released by natural sources, e.g. volcanic eruptions, evasion from water surfaces and degassing from soil. READ MORE

  2. 7. Modelling and measuring transport in fusion plasmas

    Author : Istvan Pusztai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fusion plasmas; ITG stability; microinstabilities; de-convolution; Lorentz operator; gyrokinetic equation; transport; quasilinear flux; beam emission spectroscopy; ion temperature gradient mode; electron density measurement; trapped electron response;

    Abstract : In the present thesis we consider theoretical and experimental aspects of the turbulent transport which is a crucial issue in fusion plasma physics.Experimental observations and gyrokinetic simulations show that collisions strongly influence the turbulent flux of particles.

  3. 8. Experiments with and modelling of explosively driven mangetic flux compression generators

    Author : Patrik Appelgren; Nils Brenning; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic Flux Compression; Explosives; Pulsed Power; Circuit Simulations; Hydrodynamic simulations; Electrophysics; Elektrofysik;

    Abstract : This thesis presents work performed on explosively driven magnetic flux compression generators. This kind of devices converts the chemically stored energy in a high explosive into electromagnetic energy in the form of a powerful current pulse. READ MORE

    Author : Waqas Arshad; KTH; []
    Keywords : Free-piston generators; linear machines; transverse-flux machines; hybrid vehicles; electrical machines design;

    Abstract : The presented work is about a new low-leakage lineartransverse-flux electrical machine.The machine is dimensionedfor a free-piston generator. The intended application is inseries-hybrid vehicles. The free-piston generator is anintegration of a free-piston combustion engine with a linearelectrical machine. READ MORE

  5. 10. Macroscopic Modeling of Metabolic Reaction Networks and Dynamic Identification of Elementary Flux Modes by Column Generation

    Author : Hildur Æsa Oddsdóttir; Anders Forsgren; Bernhard Palsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolic Network; Optimization; Robust Optimization; Least-squares; Column Generation; Modeling; Algorithm; Elementary Flux Mode; Metabolic Flux Analysis; Chinese Hamster Ovary Cell; Amino Acid Metabolism; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : In this work an intersection between optimization methods and animal cell culture modeling is considered. We present optimization based methods for analyzing and building models of cell culture; models that could be used when designing the environment cells are cultivated in, i.e., medium. READ MORE
