1. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators
Sammanfattning : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. LÄS MER
2. Performance Assessment of Cooperative Relay Networks with Advanced Radio Transmission Techniques
Sammanfattning : In the past decade, cooperative communications has been emerging as a pertinent technology for the current and upcoming generations of mobile communication infrastructure. The indispensable benefits of this technology have motivated numerous studies from both academia and industry on this area. LÄS MER
3. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications
Sammanfattning : This thesis concerns the mathematical modeling of transportation systems for improved decision support and analysis of transportation-related problems. The main purpose of this thesis is to develop and evaluate models and methods that exploit link flows. LÄS MER
4. Mathematical Models in Cellular Biophysics
Sammanfattning : Cellular biophysics deals with, among other things, transport processes within cells. This thesis presents two studies where mathematical models have been used to explain how two of these processes occur. Cellular membranes separate cells from their exterior environment and also divide a cell into several subcellular regions. LÄS MER
5. Homogenization of some problems in hydrodynamic lubrication involving rough boundaries
Sammanfattning : This thesis is devoted to the study of some homogenization problems with applications in lubrication theory. It consists of an introduction, five research papers (I–V) and a complementary appendix.Homogenization is a mathematical theory for studying differential equations with rapidly oscillating coefficients.
