Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. Residents in high altitude settlements are however exposed to ext
Hotet från terrorism har under 2000-talet ökat. Den 7 april 2017 blev ökningen ännu mer markant, då ett terrordåd inträffade i Stockholm. Strax efter denna händelse tillsatte regeringen en utredning för att utreda om ytterligare lagstiftning på området än den redan relativt omfattande regleringen som fanns behövdes. Utredaren kom man fram till att kriminalisering av deltagande i en terroristorganiThe threat from terrorism has during the 21st century increased. When an act of terror occurred in Stockholm on the 7th of April 2017, the threat got even more apparent. Terrorism legislation has for a long time been a well-regulated area in Swedish law, however soon after this incident the Swedish government assigned an investigation to see if further legislation in the area was required. In the
With the emergence of COVID-19, various industries felt under the pressure from limitations associated with the pandemic and transition to a work-from-home workstyle. Healthcare and Software Development is one of the industries that had to face increased demand for their products and services under severe circumstances. As an interconnection of these spheres,eHealth had to address challenges that
The goal of this thesis was to, from several randomly selected patients with diagnosed malignant and benign tumors, record optimal lambdas and respective Renyi entropies for each lambda, run a basic statistical analysis of the results and see if there is any significant difference between lambdas/Renyi entropies of malignant and benign lesions.\\ The results showed no significant difference.\\ The
Wild bees provide an important ecosystem service for humanity by pollinating many important food crops. Studies from around the world have shown declines in bee diversity and abundance. One of the reasons to these declines is the loss of natural habitats that are important for bees’ nesting and foraging. The declines are often a result of agricultural intensification. Chilli, Capsicum annuum, is a
The proof of the pudding lies in eating, and that is why 6G testbeds are essential in the progress toward the next generation of wireless networks. Theoretical research toward 6G wireless networks proposes advanced technologies to serve new applications and drastically improve energy performance. Testbeds are indispensable to validate these new technologies under more realistic conditions. This ar
Distributed massive MIMO systems are expected to be part of the upcoming generation of wireless systems where joint communication and positioning opens the possibility of exploring new applications. In this work we investigate one of the various ways of deploying these kinds of systems, through the concept of Large Intelligent Surfaces (LISs). Although the concept of LISs is not completely novel,
Distributed massive multiple-input multiple-output (D-MIMO) has been identified as a promising technology to meet the service requirements of 6 G wireless networks and beyond. The coordination between a massive number of distributed antennas introduces stiff challenges and requires a substantial amount of computing resources that must be put together with careful algorithm-architecture codesign. T
This study explores the potential of utilizing hardware built for Machine Learning (ML) tasks as a platform for solving linear Partial Differential Equations via numerical methods. We examine the feasibility, benefits, and obstacles associated with this approach. Given an Initial Boundary Value Problem (IBVP) and a finite difference method, we directly compute stencil coefficients and assign them
Use of static program analysis tools can be highly beneficial in software development, but usage is hindered by usability issues. One method to better understand these issues is to gather user feedback, but it is challenging to get developers to invest effort in giving user feedback.In this paper, we investigate whether gamification can increase user engagement in feedback collection on static ana
Critical reflection and self-reflection are two interrelated abilities universally perceived as fundamental for teachers’ professional practice. In European policy documents, these are also linked to the goal of building and consolidating education for democracy (Lenz et al., 2021, p. 9). Moreover, in the Swedish Higher Education Ordinance, they are mentioned in the second competence-and-skills ou
This study develops a strategic framework to guide the adoption of Industry 4.0 technologies across various business sectors. Using a mixed-methods approach, the research combines an extensive literature review with empirical investigations, including case studies and surveys with industry practitioners. The framework integrates advanced digital technologies, such as artificial intelligence and im
The discovery of the role of α-synuclein in the pathogenesis of Parkinson's disease (PD) has opened new possibilities for the development of more authentic models of Parkinson's disease. Recombinant adeno-associated virus (AAV) and lentivirus (LV) vectors are efficient tools for expression of genes locally in subsets of neurons in the brain and can be used to express human wild-type or mutated α-s
This research paper focuses on historical, arithmetic equity market risk premium in emerging and frontier markets. Equity market risk premium, as we know it today, has been easily estimated in developed markets; whereas, emerging and frontier markets often require different approaches to determine an appropriate equity market risk premium. I make use of a variety of methods, including volatility a
OBJECTIVE: To compare measurements of the arterial blood volume (aBV), a perfusion parameter calculated from arterial spin labelling (ASL), and cerebral blood volume (CBV), calculated from dynamic susceptibility contrast (DSC) MRI. In the clinic, CBV is used for grading of intracranial tumours. MATERIALS AND METHODS: Estimates of aBV from the model-free ASL technique quantitative STAR labelling of
The neuroprotective effect of the glial cell line-derived neurotrophic factor has been extensively studied in various toxic models of Parkinson's disease. However, it remains unclear whether this neurotrophic factor can protect against the toxicity induced by the aggregation-prone protein α-synuclein. Targeted overexpression of human wild-type α-synuclein in the nigrostriatal system, using adeno
Clinical blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) is becoming increasingly valuable in, e.g., presurgical planning, but the commonly used gradient-echo echo-planar imaging (GE-EPI) technique is sometimes hampered by macroscopic field inhomogeneities. This can affect the degree of signal change that will occur in the GE-EPI images as a response to neural
In today’s financial markets, the estimation of implied volatility of options plays an important part. Through the options prices, the implied volatility shows the size of market movement that is anticipated by the market’s participants. It is used as a benchmark for pricing all kind of assets and an erroneous number can be very costly. There are several methods for estimating and establishing pat
