1. Cost Efficient Interpolation of Potential Energy Surfaces for Quantum Dynamics
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : In calculating potential energy surfaces (PES) in quantum chemistry interpolation methods are sometimes used to get a sufficiently approximated surface. Kowalewski, Larsson and Heryudono (J Chem Phys, 148(8):084104) has developed an adaptive interpolation method to approximate a PES by polyharmonic splines interpolation. LÄS MER
2. Sponsorship : Is it a double-edged sword?
Kandidat-uppsats, Ekonomihögskolan, ELNUSammanfattning : Today, sponsorship is an integrated communication tool used for the achievement of commercial objectives. As the marketing environment changes sport sponsorship has evolved into one of the fastest growing marketing sectors. LÄS MER
3. Efficient Wave Propagation in Discontinuous Media and Complex Geometry for Many-core Architectures
Uppsats för yrkesexamina på avancerad nivå, Institutionen för informationsteknologiSammanfattning : We present an accelerated numerical solver for the scalar wave equation using one and two GPUs. We consider complex geometry and study accuracy when performing the computation in both single and double precision. The method uses a high-order accurate approximation of the derivatives using summation-by-parts operators. LÄS MER
4. On the Properties of a Few Electron-Hole system in a Double One-dimensional Harmonic Trap
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikSammanfattning : One of the most important concepts in condensed matter physics is that of ``quasi particles''. The exciton is one such quasi particle. In semi-conductors, excitons are formed by the excitation of electrons from valence band to conduction band, which creates holes in the valence band. LÄS MER
