1. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics
Sammanfattning : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. LÄS MER
2. Computer-Assisted Proofs and Other Methods for Problems Regarding Nonlinear Differential Equations
Sammanfattning : This PhD thesis treats some problems concerning nonlinear differential equations. In the first two papers computer-assisted proofs are used. The differential equations there are rewritten as fixed point problems, and the existence of solutions are proved. LÄS MER
3. Input-Output Stability Analysis of Networked Control Systems
Sammanfattning : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). LÄS MER
4. Stability of plane Couette flow and pipe Poiseuille flow
Sammanfattning : This thesis concerns the stability of plane Couette flow and pipe Poiseuille flow in three space dimensions. The mathematical model for both flows is the incompressible Navier--Stokes equations. Both analytical and numerical techniques are used. We present new results for the resolvent corresponding to both flows. LÄS MER
5. Improved Molecular Understanding of Lipid-Based Formulations : for Enabling Oral Delivery of Poorly Water-Soluble Drugs
Sammanfattning : The majority of emerging drug candidates are not suited for conventional oral dosage forms, as they do not dissolve in the aqueous environment of the gastrointestinal (GI) tract. Consequently, a large number of enabling formulation strategies have emerged. LÄS MER
