1. Monte Carlo study of disorder in electronic tight-binding models
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : Oftentimes solids are described by uniform, periodic lattices. In reality, however, there is often some disorder on some of the sites in the lattice. This disorder may come from, for example, there being a different type of atom or tightly bound electrons resulting in a larger on-site potential, affecting the electronic properties of the lattice.

2. Optimization and Bayesian Modeling of Road Distance for Inventory of Potholes in Gävle Municipality
University essay from Stockholms universitet/Statistiska institutionenAbstract : Time management and distance evaluation have long been a difficult task for workers and companies. This thesis studies 6712 pothole coordinates in Gävle municipality, and evaluates the minimal total road distance needed to visit each pothole once, and return to an initial pothole. READ MORE

3. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation
University essay from Lunds universitet/Matematisk statistikAbstract : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

4. Error estimation for neural network approximations of convection problems
University essay from KTH/Matematik (Avd.)Abstract : The problem of approximating a solution to the convection equation $\partial_t u +f\cdot\nabla_xu = h$ given data on the flux $f$, source function $h$ and a final condition $g$ is investigated. Specifically, two layer neural networks are used to approximate $f,h$ and $g$ and a solution is approximated using numerical integration. READ MORE

5. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves
University essay from Lunds universitet/Astronomi - Genomgår omorganisationAbstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.
