1. Computationally Efficient Methods in Topology Optimization
University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperAbstract : In topology optimization, iterative, gradient-based methods are used to find the material distribution of structures which maximizes some objective function, typically the structures' stiffness, or in some cases the fundamental frequency. Finite element analysis is used to compute the structural response in each iteration, leading to large systems of equations. READ MORE

2. Embedded eigenvalues for asymptotically periodic ODE Systems
University essay from Lunds universitet/Matematik LTHAbstract : In this thesis we investigate the persistance of embedded eigenvalues under perturbations of a certain self-adjoint Schrödinger-type differential operator in L^2(\mathbb{R},\mathbb{R}^n), with an asymptotically periodic potential. The studied perturbations are small and belong to a certain Banach space with a specified decay rate, in particular, a weighted space of continuous matrix valued functions. READ MORE

3. Phase Diagrams of Finite Spin Chains with Coupled Spin and Lattice Vibrations
University essay from Uppsala universitet/MaterialteoriAbstract : The spin-lattice coupling is due to itinerant electrons interacting with both spins of ions and phonons, mediating a coupling between magnetic spin moments and lattice vibrations. In this project, the coupling is studied systematically for finite quantum spin chains of size 2 – 10. READ MORE

4. Green Fuel Simulations
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Many industries have entered a new global phase which takes the environment in mind. The gas turbine industry is no exception, where the utilization of green fuels is the future to spare the environment from carbon dioxide and NOx emissions. READ MORE

5. Quantum Optimization
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : This thesis concerns the implementation of quantum algorithms on a computer vision problem called bundle adjustment. Bundle adjustment can be simplified for illustration purposes by the following example. Two different cameras take a picture of the same object in different angles. READ MORE
