  2. 21. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    Author : Ronald Whiddon; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

    Abstract : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. READ MORE

  4. 22. Convection-diffusion-reaction models of sedimentation : Numerical approximation, analysis of solutions and inverse problems

    Author : Julio Careaga; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The core of this Doctoral thesis is mainly based in the studies of one-dimensional initial-boundary value problems, which are given by a single non-linear hyperbolic partial differential equation (PDE) with non-convex flux function, or by a system of strongly degenerate parabolic PDEs, for the simulation of sedimentation processes of solid particles immersed in a fluid. Particular attention is paid to the case of settling in vessels with varying cross-sectional area. READ MORE

  5. 23. Finite Element and Neuroimaging Techniques toImprove Decision-Making in Clinical Neuroscience

    Author : Xiaogai Li; Svein Kleiven; Hans von Holst; Bernhard A Schrefler; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic brain injury; Intracranial Pressure; Brain edema; Gravitational force; Finite Element Model; Poroelastic parameter; Decompressive craniotomy; Image registration; Water content; Strain level; Diffusion Weighted Imaging;

    Abstract : Our brain, perhaps the most sophisticated and mysterious part of the human body, to some extent, determines who we are. However, it’s a vulnerable organ. When subjected to an impact, such as a traffic accident or sport, it may lead to traumatic brain injury (TBI) which can have devastating effects for those who suffer the injury. READ MORE

  6. 24. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Author : Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Abstract : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. READ MORE

  7. 25. Reactive Sputter Deposition of Functional Thin Films

    Author : Lina Liljeholm; Jörgen Olsson; Ilia Katardjiev; Tomas Nyberg; Gonzalo Fuentes Iriarte; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin film; reactive sputtering; coating; resonator; sensor; FBAR; SMR; aluminum nitride; Al; B N; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Thin film technology is of great significance for a variety of products, such as electronics, anti-reflective or hard coatings, sensors, solar cells, etc. This thesis concerns the synthesis of thin functional films, reactive magnetron sputter deposition process as such and the physical and functional characterization of the thin films synthesized.
