1. Discrete Kinetic Models and Conservation Laws
Sammanfattning : Classical kinetic theory of gases is based on the Boltzmann equation (BE) which describes the evolution of a system of particles undergoing collisions preserving mass, momentum and energy. Discretization methods have been developed on the idea of replacing the original BE by a finite set of nonlinear hyperbolic PDEs corresponding to the densities linked to a suitable finite set of velocities.

2. Classification of Normal Discrete Kinetic Models
Sammanfattning : “In many interesting papers on discrete velocity models (DVMs), authors postulate from the beginning that the finite velocity space with "good" properties is given and only after this step they study the Discrete Boltzmann Equation. Contrary to this approach, our aim is not to study the equation, but to discuss all possible choices of finite phase spaces (sets) satisfying this type of "good" restrictions. LÄS MER
3. Quantum Kinetic Theory for Plasmas : spin, exchange, and particle dispersive effects
Sammanfattning : This thesis is about developing and studying quantum mechanical models of plasmas. Quantum effects can be important at high densities, at low temperatures, and in strong electromagnetic fields, in various laboratory and astrophysical systems. LÄS MER
4. Kinetic Models in Life Science — Contributions to Methods and Applications
Sammanfattning : Kinetic models in life science combine mathematics and biology to answer questions from areas such as cell biology, physiology, biotechnology, and drug development. The idea of kinetic models is to represent a biological system by a number of biochemical reactions together with mathematical expressions for the reaction kinetics, i.e. LÄS MER
5. Kinetic garment construction : remarks on the foundations of pattern cutting
Sammanfattning : Fashion designers are presented with a range of different methods for pattern cutting, and the interest in this field has grown rapidly over the past few years. This growth is both due to the publication of a number of works dealing with the subject in different ways and the fact that a growing number of designers emphasise cutting in their creative practices.
