1. Solving Ordinary Differential Equations and Systems using Neural Network Methods
University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)Abstract : The applications of differential equations are many. However, many differential equations modelling real-world scenarios are very complex and it can be of great difficulty to find an exact solution if one even exists. Thus, it is of importance to be able to approximate solutions of differential equations. READ MORE

2. Implementation and study of boundary integral operators related to PDE:s in the plane
University essay from Lunds universitet/Matematik LTHAbstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

3. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods
University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenAbstract : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. READ MORE

4. Finite Difference Approximations for Wave Propagation
University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenAbstract : Finite difference approximations are methods for solving differential equations by approximating derivatives. This work will begin with how to solve a partial differential equation (PDE) called the advection equation, ut + cux = 0. READ MORE

5. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications. The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.
