6. Alternatives for Finite Element Analysis of Blade Forging
Sammanfattning : This thesis is a theoretical and numerical study of the weaknesses and capabilities of alternative finite element procedures for simulation of the blade forging problem and also an analysis of the practical aspects of that process. An overview is presented of the finite element method for non-linear problems with elastoplastic constitutive relations, focusing on quasistatic implicit and dynamic explicit approaches. LÄS MER
7. Heat Flow in Building Components, Experiment and Analysis
Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER
8. Adaptive Algorithms and High Order Stabilization for Finite Element Computation of Turbulent Compressible Flow
Sammanfattning : This work develops finite element methods with high order stabilization, and robust and efficient adaptive algorithms for Large Eddy Simulation of turbulent compressible flows. The equations are approximated by continuous piecewise linear functions in space, and the time discretization is done in implicit/explicit fashion: the second order Crank-Nicholson method and third/fourth order explicit Runge-Kutta methods.

9. High-order finite element methods for incompressible variable density flow
Sammanfattning : The simulation of fluid flow is a challenging and important problem in science and engineering. This thesis primarily focuses on developing finite element methods for simulating subsonic two-phase flows with varying densities, described by the variable density incompressible Navier-Stokes equations.

10. Capacitive Biosensor - A Tool for Ultrasensitive Analysis : Application in Clinical Analysis and Process Monitoring
Sammanfattning : Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances. LÄS MER
