Abstract:

This dissertation project was designed to examine the relationship between alpha sleep and information processing during sleep in persons with fibromyalgia. The study tested the following hypotheses: (1) persons with alpha sleep are more sensitive to external stimuli during sleep than non-alpha sleepers (2) alpha sleepers are more likely to identify polysomnographically defined sleep as wakefulness than non-alpha sleepers and (3) alpha sleepers are more likely to complain of shallow and non-restorative sleep than non-alpha sleepers. To assess the extent to which subjects manifested alpha sleep

Abstract:

In this work we mainly focus on two main aspects of interest within the field of Relativistic Quantum Information. We first expand on the current knowledge of the effects of relativity on entanglement between global field modes. Within this aspect, we focus on two topics: we address and revise the single mode approximation commonly used in the literature. We study the nonlocal correlations of charged bosonic field modes and the degradation of entanglement initially present in maximally entangled states as a function of acceleration, when one observer is accelerated. In the second part of this

Problem Deciding where to spend the information system investment budget with respect to strategic priorities is important for companies, but it is far from every company that does it. There is no consesus in the literature on how information system investment decisions should be assessed. This case study is conducted on Alpha AB. The company consists of several departments that each require different kind of information to support, improve and facilitate their area of operation. They are in the process of deciding where to spend their investment budgets. Purpose The Purpose of this thesis is

Abstract:

Europa is one of the most interesting satellites in the solar system in the search ofextra-terrestrial life, as it harbours an interior water ocean under its icy surface. Watervapour in Europa’s atmosphere has been previously observed, suggesting water plumeeruptions from the surface. These plumes could potentially originate from the subsurfaceocean, and as such contain ocean constituents that can be examined in orbit. Twoobservations of Europa’s far-ultraviolet shadow on Jupiter were made by the HubbleSpace Telescope in 2018 and 2019. It was observed in Lyman-α (1 216 Å), a spectral lineof hy

<p>This master’s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. </p><p>Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped cache

Abstract:

Uranus is one of the least explored planets in our solar system. Event though the Uranian Ly-α emission has been a subject of study for decades, there is not a consensus on the sources contribution to the total signal. This thesis aims to analyse the contribution from scattering of the solar flux to the Uranian Ly-α dayglow by solving the radiative transfer equation in a parameter study for the atmosphere. The sources are solar Ly-α resonant scattering and Rayleigh scattering by atomic and molecular hydrogen respectively. The radiative transfer equation is solved using the Feautrier Method Pro

Abstract:

In self-play reinforcement learning an agent plays games against itself and with the help of hindsight and retrospection improves its policy over time. Using this premise, AlphaZero famously managed to become the strongest known Go, Shogi, and Chess entity by training a deep neural network from data collected solely from self-play. AlphaZero couples this deep neural network with a Monte Carlo Tree Search algorithm that drastically improves the networks initial policy and state evaluation. When training AlphaZero relies on the final outcome of the game for the generation of training labels. By

Abstract:

It is well known that the branching factor of a computer based board game has an effect on how long a searching AI algorithm takes to search through the game tree of the game. Something that is not as known is that the branching factor may have an additional effect for certain types of AI algorithms. The aim of this work is to evaluate if the win rate of an evolutionary AI algorithm is affected by the branching factor of the board game it is applied to. To do that, an experiment is performed where an evolutionary algorithm known as “Genetic Minimax” is evaluated for the two low branching facto

Parallel-plate avalanche counters, PPACs, are commonly used to detect fission fragments. The PPAC detects them and mark (very accurately) the time of detection. Such measurements can be used to measure the neutron energy (via time-of-flight) to study neutron-induced fission.This project report provides a method that, together with the discussed improvements, allows the fabrication of good quality PPAC detectors. Several PPACs are manufactured and the electrodes are built from 0.9 µm thick mylar foils which are evaporated with a 40-80 nm thin layer of aluminum.The developed PPACs are characteri

Concerning node similarity, we focus on improving the diffusive process leading to compute this similarity (e.g. Commute Times) by means of modifying or rewiring the structure of the graph (Graph Densification), although some advances in Laplacian-based ranking are also included in this document. Graph Densification is a particular case of what we call graph rewiring, i.e. a novel field (similar to image processing) where input graphs are
