The aim of this thesis has been to investigate the legal conditions and process for triggering Credit Default Swaps, which are derivative instruments to shift credit risk exposure between parties in an underlying financial instrument. The condition is called credit event and a case study has been done on the Greek credit event in 2012. The thesis shows that there is a clear and robust framework o
Previous studies indicated that skylights can improve the daylight conditions in house or office buildings, decrease the electricity demand for lighting, provide natural ventilation and reduce the heating demand through passive solar heat gain exploitation. This thesis analyses the effect of skylights on the energy use, daylight conditions and thermal comfort in a classroom. The study is performed
This essay addresses the needs of so called ‘climate migrants’. It focuses exclusively on the relocation of the population of Kiribati, a small island nation in the Pacific Ocean whose very existence is threatened by the effects of climate change. With the principles of causality, morality, capacity and community, Miller’s Connection Theory provides the study with a framework for discussing the di
The body shows impressive control capabilities in terms of the speed and the precision with which movements can be carried out under a wide variety of circumstances. The cerebellum and brainstem nuclei, including the cuneate nucleus, are believed to play a crucial role in this control. If these control mechanisms can be unveiled, this could yield important insights in not only medicine and neuroph
This work presents an observer design for grid current and capacitor voltage of voltage source pulse-width modulation (PWM) converters with LCL filter. Theoretical aspects including the mathematical LCL filter system observability, observer placement strategy and practical discretization implementation. It gives insight to mathematical modelling of the line filters dynamics. By the limitations of
The importance of the alluring goal of having the “perfect” or “true” information is more than visible in the financial world. In portfolio management financial correlation matrices measure the unsystematic correlations between assets e.g. stocks. Finding the true correlations between stocks would enable the creation of portfolios with less risk. In reality this information is more than hard to co
This paper explores freshwater reservoir greenhouse gas emissions from a policy perspective. Existing science on reservoir emissions indicates that reservoirs can emit significant amounts of greenhouse gases and this is of particular concern for tropical reservoirs. Current scientific knowledge has led to some precautionary policy measures, but, in general, policy development has been slow. At the
Covid-19 has triggered a massive global challenge with 1,576,069 overall confirmed cases, 1,545,429 recovered cases, and 30,640 deaths across Pakistan. Epidemiological models have always played an important role in understanding the dynamics of such infectious diseases. The severity of Covid-19 infection depends on several factors such as immune system and virus variants. Although detailed epidemi
Failure mode and effects analysis (FMEA) is a critical but labor-intensive process in product development that aims to identify and mitigate potential failure modes to ensure product quality and reliability. In this paper, a novel framework to improve the FMEA process by integrating generative artificial intelligence (AI), in particular large language models (LLMs), is presented. By using these ad
BACKGROUND: Medium vessel occlusions (MeVO) can be either isolated events (primary), or secondary to thrombus migration from a large vessel occlusion to a medium-sized vessel. Outcomes following endovascular thrombectomy (EVT) in the middle cerebral artery (MCA) may differ between primary and secondary MeVOs. This study aimed to assess the association between primary/secondary MeVOs and clinical o
Background: Recurrent coarctation of the aorta (re-CoA) is a well-known although not fully understood complication after surgical repair, typically occurring in 10%–20% of cases within months after discharge. Objectives: To (1) characterize geometry of the aortic arch and blood flow from pre-discharge magnetic resonance imaging (MRI) in neonates after CoA repair; and (2) compare these measures bet
One of the main challenges as the market for fully commercial electrified vehicles quickly expands is predicting the electromagnetic interference (EMI) in traction voltage systems (TVSs) in differential mode (DM) and common mode (CM). The number of subsystems connected to vehicle TVSs is increasing, and thus, so are the electromagnetic compatibility (EMC) requirements. These requirements should ma
AI cancer detection models require calibration to attain the desired balance between cancer detection rate (CDR) and false positive rate. In this study, we simulate the impact of six types of mismatches between the calibration population and the clinical target population, by creating purposefully non-representative datasets to calibrate AI for clinical settings. Mismatching the acquisition year b
In this paper we show that OpenAI’s Large Language Model (LLM) GPT perform remarkably well when used for title and abstract eligibility screening of scientific articles and within a (systematic) literature review workflow. We evaluated GPT on screening data from a systematic review study on electric vehicle charging infrastructure demand with almost 12,000 records using the same eligibility criter
Global policies, legislation, and eco-friendly initiatives have induced the steel industry to integrate sustainable development approaches. Sustainability requires all phases from raw material sourcing to transportation to waste and carbon footprint elimination—yielding positive effects. This research employs a two-step approach in sustainability. The first phase entails conducting a systematic li
The delay between the origin of animals in the Neoproterozoic and their Cambrian diversification remains perplexing. Animal diversification mirrors an expansion in marine shelf area under a greenhouse climate, though the extent to which these environmental conditions directly influenced physiology and early organismal ecology remains unclear. Here, we use a biogeochemical model to quantify oxygen
Background Suicide attempts are common in youth and have potentially lethal outcomes. Effective treatments targeting suicide attempts are scarce. Objective To assess the feasibility and preliminary efficacy of a family-based cognitive behavioural treatment relative to an active control for youth with suicidal behaviour. Methods 30 youths (93% female; mean (SD) age=14.6 (1.5) years) residing in Swe
Key questions for understanding hippocampal function in memory and navigation in humans are the type and source of visual information that reaches the human hippocampus. We measured bidirectional pairwise effective connectivity with functional magnetic resonance imaging between 360 cortical regions while 956 Human Connectome Project participants viewed scenes, faces, tools, or body parts. We devel
