Geoportals are increasingly used for searching, viewing, and downloading spatial data. This study concerns methods to improve the visual presentation in viewing services. When spatial data in a viewing service are taken from more than one source there are often syntactic, semantic, topological, and geometrical conflicts that prevent maps being fully consistent. In this study we extend a standard v
Engineers require high-quality data for the design and implementation of today’s software, especially in the context of machine learning (ML). This puts an emphasis on the need for the publication and sharing of data from and between organizations, public as well as private. Following the paradigm of open innovation, open data provide a mechanism to increase the availability of information, offeri
Automatic interpretation of reading from the brain could allow for many interesting applications including movement of prosthetic limbs and more seamless manmachine interaction. This work studied classification of EEG signals used in a study of memory. The goal was to evaluate the performance of the state of the art algorithms. A secondary goal was to try to improve upon the result of a method tha
IKEA, a company well known around the world for their furniture, is also keen on using digital solutions to improve the customer experience. One of these solutions is the self-serving kiosk, a 27" touchscreen, that helps the customers find and buy products. As many other companies of similar size, IKEA wants to use the data from their digital solutions, as a base for some of their decision ma
Finding vulnerabilities in open source software is an important part of software security. Software security is in turn a vital part in risk management and making risk assessments. The purpose of this thesis is to help organisations make decisions about vulnerabilities they have in their software programs by helping them make their own risk assessment. Our research uses the Common Vulnerability Sc
An experimental campaign took place at the Argonne National Laboratory (ANL) in the summer of 2020. Its goal was to study the exotic modes of decay of neutron-deficient nuclei located near 56Ni. For this thesis, the part of interest from the campaign is the experiment studying the fusion-evaporation reaction resulting from the collision of high-energy nuclei of 36Ar and a 24Mg target, creating exc
Selection bias in non-probability samples presents a significant challenge in IoT device di- agnostics data analysis, where incomplete or systematically missing data can compromise the validity of analytical insights. Our project proposes a comprehensive statistical frame- work to correct for that bias, using real-world data from Axis Communications AB. The project explores three primary methodolo
This study focuses on understanding how archaeologists interact with and reuse 3D data during excavation, drawing on an ad-hoc experiment and a discourse analysis approach taken from socio-linguistic disciplines. The experiment, conducted during the excavation of an Iron Age ‘central place’ in Sweden, reveals the multifaceted utility of 3D models in archaeological discussions. Our analysis shows t

This thesis seeks to explore the potential for 3D archaeological datasets to become the ‘living resources’ advocated by Morgan and Wright (2018). This process is examined through lenses of object agency, object biography, Chaîne opératoire, formation processes and posthumanist theory with an aim to assess the capacity of digital approaches for enabling the self-reflexive ‘slow archaeology’ idealis
The overall aim of the current project is to investigate the possibility of using people's mobile phones to locate people in a tunnel environment, both during normal operation and during an emergency. As part of the project, a technology for locating people based on Wi-Fi communication between access points in a tunnel and the user's mobile phone is investigated. To examine the precision of the lo
The Schrems II judgement delivered on 16 July of 2020 was the second time that an EU court invalidated an adequacy decision authorizing EU-US data transfer. Doubts gather around the suitability of adequacy decision being an instrument to govern cross-border data transfer. This thesis therefore wishes to explore the deficiencies of such an instrument posed by the current regime as established in th
The internet has brought about vast knowledge in the form of “data” to the 21st century. As a part of its digital single market strategy, the European commission has sought to develop a European data economy and consequently the regulation and allocation of data is becoming increasingly important. Both the General Data Protection Regulation (“GDPR”) and the Database Directive 96/9 (“DbD”) confer r
Objective: To compare the healthcare costs and effects of budesonide/formoterol in,a single inhaler with those of budesonide and formoterol monotherapies, and placebo, in a multinational study in patients with chronic obstructive pulmonary disease (COPD), National Heart, Lung and Blood Institute (NHLBI)/WHO Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages III or IV. Previous an
Portfolio selection involves a trade-off between maximizing expected return and minimizing risk. In practice, useful formulations also include various costs and constraints that regularize the problem and reduce the risk due to estimation errors, resulting in solutions that depend on a number of hyperparameters. As the number of hyperparameters grows, selecting their value becomes increasingly imp
