This thesis describes the development process of a digital tool that can be used by locksmiths to quickly and easily find the right components for repairing and replacing electronic locking mechanisms. The tool took the form of a mobile application and was developed in collaboration with Robust Ellåsning AB in Malmö, Sweden. The report describes an iterative, human-centered design process, from da
This thesis will be an investigation into different proofs of Completeness in first-order logic. Particular attention will be put on analyzing the role of the Ultrafilter Lemma and its necessity in proving the Completeness Theorem. An attempt will be made to develop a proof that separates out this non-constructive aspect, but still uses the law of excluded middle. The overall aim is to understand
A reliable forward prediction of time series data is essential for optimising resource allocation, mitigating risks, and enhancing strategic decision-making across various domains. However, the limited historical data available can pose a challenge for accurate modelling. Conversely, transformer architectures, renowned for their success in natural language tasks through zero-shot inference, demons
In this project, I investigate the combination of Natural Language Processing (NLP) with Item Response Theory (IRT) to advance the assessment and scoring of open response items. Traditional psychometric assessments are grounded in well-defined quality standards, yet assessments based on natural language have missed meeting these standards. To address this gap, I integrate NLP processed open respon
Monte Carlo simulation is a numerical method that can simulate complex physical systems and is widely used in the field of medical optics. For example, the Monte Carlo method was used to evaluate the effectiveness of near-infrared spectroscopy (NIRS) in the detection of intracranial hematoma (ICH). However, due to the relatively complex brain structure, the current simulation model is relatively s
Spatial transcriptomics, a powerful technique that merges sequencing and spatial data, offers unprecedented resolution for studying gene expression within tissues. This study focuses on developing a pipeline to design probes for Multiplexed Error-Robust Fluorescence In Situ Hybridisation (MERFISH) experiments to investigate the spatial distribution of the lung microbiome. Metagenomic data analysis
In 1997 the Ugandan government introduced a reform program with the ambition to implement universal primary education. The abolition of tuition fees would ideally guarantee access to the public service delivery system as far as primary education is concerned and help to integrate underprivileged groups with the rest of the diverse society. The launch of universal primary education in Uganda implie
South East Asia, and Thailand in particular, are experiencing rapid population ageing. In Thailand older people are increasing in both proportion of the population and absolute number. Adaptations are needed to support this ageing population and to prevent poverty in old age. Since 2009 Thailand has had a minimum universal social pension, the Old Age Allowance (OAA) for all citizens aged 60 and ov
Issue of study: The plastic injection moulding industry has become highly competitive in terms of lead times and pricing, following an increase in low-cost manufacturing from Asia, as a part of the full supply chain. To remain competitive, mould tool manufacturers are looking to complement new tool manufacturing with local after-sales services in countries where their mould tools are being used. U
In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. On-chip memories in CMOS technologies can be categorized as sta
This thesis investigates the effect of commuting time on labour supply using US household survey data. To circumvent biased estimates as working hours and commuting time are jointly determined by the worker, a first differences approach is carried out, in which changes in the commute are assumed to be exogenous. The estimates suggest that there is no causal effect on labour supply that can be deri
This study aims to contribute to the knowledge of activism, specifically the culture of political activism at the level of the individual lived experience. Ernesto Laclau and Chantal Mouffe’s Hegemony and Socialist Strategy Towards a Radical Democratic Politics (2014) draws from Antonio Gramsci’s concept of cultural hegemony and develops a theoretical framework for how social movements can effecti
This study investigates how the political will for strengthening resilience has developed within the city of Bristol, focusing on how this is shaped by factors at local, national and international scales. Thematic analysis of Bristol City Council policy documents and interviews with participants from a range of different organisations throughout the city are used to gather data. The findings are a
The purpose of this master’s thesis project is to aid Thomson Reuters to forecast soil moisture, enhancing the agricultural productivity of its clients. This thesis focuses on testing the company’s HBV model (HBV-TR) to accurately produce daily soil moisture values in Brazil, France, and the U.S.A. The problem is that, up to this day, the most reliable monitoring of this soil water content is als
There is a growing expectation in the field of sustainable development that cities are the most suitable scale for addressing global environmental issues, particularly through their ability to mobilize local actors. Business improvement districts (BIDs) are a form of public-private partnership (PPP) in cities typically established by associations of private actors that aim to generate value in com
Many economists agree that financial development and economic growth have a positive relationship, that financial structures have been critical for many countries to achieve modern economic growth. In the past decades, foreign investment has become more widespread in the entrepreneurial world, and the banking sector has not been an exception. Mexico experimented during the late 1990’s an unprecede
The digitalization of the music industry has meant a drastic increase of public accessibility of recorded music, which has transformed the way in which music is being consumed. From initially being restricted by the physical disposition of CDs and vinyl, the prospect of digital downloading and music streaming has rapidly transformed the music landscape as the world knows it. The music industry rev
Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. A consequence of non-radiative surface recombination is a reduction of a total recombination lifetime. This is in turn limits an internal quantum e
Risk matrices are tables with rows representing consequences, and columns representing frequencies. The risk matrix is considered a simple and convenient tool for visualizing risk. However, it has faced critique from the scientific community. Though risk matrices are extensively applied in practice for visualizing results from coarse risk analyses, there is limited research regarding guidance on i
In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. This thesis introduces a linear algebra framework for closed orbit perturbation and correction, its implementation as a Python package and its use for three studies in HL--LHC: orbit corrector bu
