1. Summation By Parts Finite Difference Methods with Simultaneous Approximation Terms for the Heat Equation with Discontinuous Coefficients
University essay from Linnéuniversitetet/Institutionen för matematik (MA)Abstract : In this thesis we will investigate how the SBP-SAT finite difference method behave with and without an interface. As model problem, we consider the heat equation with piecewise constant coefficients. The thesis is split in two main parts. READ MORE

2. Summation By Part Methods for Poisson's Equation with Discontinuous Variable Coefficients
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Nowadays there is an ever increasing demand to obtain more accurate numericalsimulation results while at the same time using fewer computations. One area withsuch a demand is oil reservoir simulations, which builds upon Poisson's equation withvariable coefficients (PEWVC). READ MORE

3. Last Minute Bidding on Tradera
University essay from Lunds universitet/Nationalekonomiska institutionenAbstract : In online auctions bidding frequency tends to increase towards the last minutes of the auction. This thesis investigates why bidders might choose to engage in last minute bidding, sniping, in Tradera auctions (Tradera is a Swedish subsidiary of eBay). Tradera uses a hard-close rule and a second-price rule. READ MORE

4. Simulation of Wave Propagation in Discontinuous Media and Complex Geometries
University essay from Institutionen för informationsteknologiAbstract : A strictly stable high order finite difference (HOFD) scheme for the scalar wave equation with discontinuous coefficients corresponding to inhomogeneity in the underlying media is constructed using summation - by - parts (SBP) operators. The domain of the equation is allowed to be complex in the sense that it can not be smoothly mapped from the unit square. READ MORE
