16. 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.

17. On relations between classical and quantum theories of information and probability
Sammanfattning : In this thesis we study quantum-like representation and simulation of quantum algorithms by using classical computers.The quantum--like representation algorithm (QLRA) was introduced by A. Khrennikov (1997) to solve the ``inverse Born's rule problem'', i.e. LÄS MER

19. Doctoral thesis: On the Role of Process Regions at Stationary and Growing Cracks
Sammanfattning : Studies of crack behaviour and fracture are generally performed using continuum analysis. Thus, the process region is either not considered at all or assumed to be point-sized. In the latter case it is often ascribed a desired property, usually the ability to consume energy. LÄS MER
20. Optimal Stopping Domains and Reward Functions for Discrete Time American Type Options
Sammanfattning : Avhandlingen behandlar problemet att välja tidpunkt för att lösa in en amerikansk option. En amerikansk option ger ägaren rätten att köpa eller sälja en underliggande vara för ett fast pris, kallat lösenpriset, fram till och med en förbestämd tid, den så kallade slutdagen. LÄS MER
