Access to digital infrastructure in highly digitalized societies is shaped not only by the availability of technology but also by the administrative arrangements that govern access to it. This study examines how non-EU international students at Lund University experience and navigate exclusion from Sweden’s digital financial infrastructure through the case of Swish, a mobile payment system widely
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
This project investigates the combined use of a Time Projection Chamber (TPC) prototype and Hadronic Range Detectors (HRDs) developed for the HIBEAM beamline at the European Spallation Source (ESS). The data analysed in this work were collected during a test experiment the Proteus C-235 cyclotron proton source in Krakow where protons were scattered from a carbon deuteron target. The aim of this st
The use of NADH as fuel for industrial enzymatic reactions has gained large interest over the years. However, novel catalytic materials and process are required to produce NADH from NAD+. This thesis investigated the deposition and characterization of catalytic materials on p-type silicon microwire (SiMW) photoelectrodes for the photoelectrochemical reduction of NAD⁺ to enzymatically active NADH.
Architecture exists at the intersection of art and engineering, materially defined by the spaces enclosed within physical boundaries. Just as natural language processing allows machines to parse written text, artificial intelligence can comprehend architectural space when it is translated into a structured, objective format. This thesis proposes a novel machine learning framework for the automated
Alzheimer's disease (AD), the leading cause of dementia, is characterized by the accumulation of amyloid-β (Aβ) plaques and tau neurofibrillary tangles. Fluid biomarkers can accurately detect these.Plasma biomarkers are of particular interest, given that they are minimally invasive and low-cost, with potential for large-scale implementation, particularly in settings where cerebrospinal fluid (CSF)
Heterogeneous explainable spatiotemporal graph neural networks for disease outbreak surveillance using individual and aggregated-level data Fine-scale forecasting of severe infectious-disease outcomes can support local public-health planning, but most spatiotemporal forecasting models represent geographic areas as homogeneous nodes and do not explicitly retain information from individuals and hous
Dijets are produced in abundance at the Large Hadron Collider as predicted by quantum chromodynamics (QCD). However, several theories beyond the Standard Model of Particle Physics predicts new phenomena, which also result in dijet final states. This thesis presents searches for such new phenomena using different techniques. One approach is to look for jets, that originate from top quarks. We know,
Objective: We evaluated the claim that interventions to improve academic achievement can reduce the risk for alcohol use disorder (AUD). Method: Using nationwide data for individuals born in Sweden from 1972 to 1981 (n = 930,182), we conducted instrumental variable and co-relative analyses of the association between academic achievement and AUD with a mean 21.4-year follow-up. Our instru-ment, use
Full-field transmission X-ray microscopy (TXM) is a well established technique, available at various synchrotron beamlines around the world as well as by laboratory benchtop devices. One of the major TXM challenges, due to its nanometre-scale resolution, is the overall instrument stability during the acquisition of the series of tomographic projections. The ability to correct for vertical and hori
Implementation of Bridge weigh-in-motion (B-WIM) measurements and probabilistic approaches in bridge assessment may reveal hidden bridge reserves and changes in reliability levels over their projected service life, providing a key input for optimized bridge management. But, as scientists and engineers and at the same time vendors of our own ideas, we need to be in position to present the results o
Structural Health Monitoring (SHM) has been a subject of major international research in Civil Engineering structures mainly during the last 20 years. While in the beginning, SHM mainly focused on sensor developments, nowadays practical implications regarding the acquisition, collecting and processing of data are being addressed. Indeed, SHM systems have been evolving along the two last decades an
There is a large financial incentive to minimise operations and maintenance (O&M) costs for offshore wind power by optimising the maintenance plan. The integration of condition monitoring (CM) and structural health monitoring (SHM) may help realise this. There is limited work on the integration of both CM and SHM for offshore wind power or the use of imperfectly operating monitoring equipment.
Safety in density (SID) potentially explains the safety in numbers (SIN) phenomenon by positing that ‘the SIN effect can be reproduced simply through encouraging behaviour that leads to the formation of higher-density cyclist groups’. The study further explores this hypothesis using event-based exposure, queues and groups of road users. Using three different definitions of encounters between road u
Most signals detected by genome-wide association studies map to non-coding sequence and their tissue-specific effects influence transcriptional regulation. However, key tissues and cell-types required for functional inference are absent from large-scale resources. Here we explore the relationship between genetic variants influencing predisposition to type 2 diabetes (T2D) and related glycemic trai
CONTEXT: Once islet autoantibody-positive individuals are identified, predicting which individuals are at highest risk for type 1 diabetes (T1D) is important. A metabolic risk score derived from 2-hour oral glucose tolerance test (OGTT) data, the Diabetes Prevention Trial-Type 1 risk score (DPTRS), can accurately predict T1D. However, 2-hour OGTTs are time-consuming and costly. OBJECTIVE: We aimed
Obesity is the main risk factor behind insulin resistance and type 2 diabetes. Still, the mechanism behind adipocyte dysfunction is not yet resolved. Recently, we reported that rapid actin remodeling correlates with adipose cell size changes after short-term overfeeding. Therefore, we hypothesized that the actin-driven myocardin-related transcription factor (MRTF-A) contributes to impaired mature
A modification to our previous simulation of breast anatomy is proposed to improve the quality of simulated x-ray projections images. The image quality is affected by the voxel size of the simulation. Large voxels can cause notable spatial quantization artifacts; small voxels extend the generation time and increase the memory requirements. An improvement in image quality is achievable without redu
Based on extensive qualitative (interviews, n50) and quantitative data (survey questionnaire, n3200), this paper identifies management – and not only managerial regimes – as a problem in in public sector work places. The paper specifically explores what nurses and social workers identify as central areas of conflict shaping their work, and what forms of structural and organizational change they vi
