A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. The unit cell which is repeatable in al
While the Swedish debate on crime often centers around crime, punishment, and offenders, there is notably less attention dedicated to those who are exposed to crime. This discrepancy is particularly evident in the lack of comprehensive theories explaining who becomes a victim. This thesis investigates whether a pattern can be identified between what kind of background or exposure of crime and bein
Due to the Basel III regulations, Value-at-Risk (VaR) as a risk measure has become increasingly important in Europe for financial institutions. But even though it has become an important risk measure, both internally within company reporting and externally due to legislation, there is no one single way to forecast VaR that has yet proven to be superior. The aim of this paper is to examine differen
Markov Regime-Switching GARCH (MRS-GARCH) models have been gaining popularity due to their ability to account for shifts volatility regimes that tend to characterize returns series. Previous empirical studies have shown that this capacity to capture the volatility dynamics leads to a superior forecasting power of the MRS models. We investigate the performance of these models in quantifying and man
The white blood cell count and differential is an important part of diagnosing a number of medical conditions. Instead of doing this by manual microscopy, CellaVision’s technology has automated the process of finding and classifying white blood cells. To support a diagnosis it is desired that the system can produce cytoplasm-to-nucleus-ratio. This ratio is calculated from a segmented image where t
The standard interpretation of aggregate excess sensitivity is that it represents the economy share of non-Ricardian households. However, household level evidence suggests that excess sensitivity can also be explained by the comovement of consumption and income over the lifetime, which occurs due to retirement and changes in household size. If aggregate estimates of excess sensitivity can in part
Progress on Sustainable Development Goal 4: Quality Education (SDG4) has been insufficient and knowledge of how it is implemented into domestic contexts remains limited. Using norm diffusion theory as a framework, this thesis is a comparative study of SDG4 implementation in five countries around the world. By analysing both the discursive and practical impact of SDG4, this thesis has studied if an
The purpose with this study is to examine Fiske et al. (2002) hypothesis that stereotypes are best described from without the two dimensions warmth/competence. The survey is a scaling study where the participants' (n = 102) similarity judgements from a set of social groups were analyzed using the statistical tool PCA (Principal Component Analysis). The result of the PCA proposes a four-dimensi
In the context of the COVID-19 pandemic, this thesis focuses on the bottom-up conceptualisation of the notion of rule of law, developed by a group of activists against a COVID vaccine passport enforced in Italy (so-called Green Pass), and their subsequent everyday acts of resistance. By using a multimodal digital ethnography methodology, centred on both in-person and digital informal encounters, t
The anticolonial uprising in 1920 against the British occupation of the provinces of Mosul, Baghdad, and Basra marked an unprecedented escalation in resistance and opposition to the colonial forces. While most narratives of this uprising focus on the more significant events across the lower and middle Euphrates, earlier, unsuccessful episodes of anticolonial resistance also emerged in the Jazirah
Women’s rights are under pressure worldwide. NGOs working in women’s rights face new and recurring challenges in light of recent abortion bans and increased domestic violence against women during COVID-19, for instance. The Convention on the Elimination of all forms of Discrimination Against Women (CEDAW) of the United Nations, offers the promise of an ideal world free from discrimination against
Climate change is an ever-increasing global phenomenon that affects the world on many levels, most notably environmentally. As some countries have better resources than others, and some are more vulnerable to the effects of climate change than others, climate change has a varied priority among the countries in the world. The way to prevent climate change from increasing is through acts of climate
This paper seeks to examine trends in Chinese household consumption. It is comprised of a two-fold study, which undertakes both an exploratory and an explanatory approach. First, an analysis into the nature of household consumption examines trends in purchasing habits. Specifically, data on the consumption and prevalence of durable household goods and major food commodities is gathered to establis
Diffusion is a molecular phenomenon and can be described as the process by which matter is transported from one part of a system to another as a result of random molecular motion. The diffusion coefficient is then a quantity that describes the mobility of the molecules in a media. In recent years, methods have been developed to image the diffusion of water in human tissue using magnetic resonance
The aim of the thesis is to evaluate the reaction in fiscal stance in EMU with the purpose to investigate if there is a need for discretionary fiscal policy as a stabilizing mechanism due to the existence of country-specific disparities in order to counteract business cycle fluctuations in the Monetary Union. The second objective is to analyse the role of discretionary fiscal policy during three d
