Structural investigation of ductile deformations across the Frontal Wedge south of Lake Vättern, southern Sweden

Deformationszonen kallad ”Frontal wedge” är ett system av N-S branta och vertikala deformationszoner i gränsen mellan Svekonorvegiska och Sekorareliska provincen, i södra Sverige. Ursprung av dessa strukturer är inte fullt förstått och under de senaste årtiondena har endast ett fåtal undersökningar gjorts på dessa deformationszoner. Det finns flera olika tolkningar och modeller för bildandet av stThe Frontal wedge is a system of N-S trending steep to vertical deformation zones at the border between the Sveconorwegian and Svecokarelian provinces in south-central Sweden. The origin of these structures is not fully understood and few investigations have been done on these deformation zones during the past decades. There are various interpretations of and models for the formation of the struct

Simulating Space

he late visionary architect Lebbeus Woods once said; "We inhabit space in which we are not sure how to move". With increasing environmental destruction and rising see levels we might soon be forced to literally inhabit space, in which we definitely are not sure how to move. Astronauts have continously reported problems with orienting in space and of unhomely space interiors. So, what wou

The Relationship between Tax Avoidance and ESG Ratings

This study investigates the relationship between tax avoidance and corporate responsibility measured through ESG ratings among Swiss listed companies between 2010 and 2019. In the first part of the analysis, the aim is to identify whether Swiss firms provide evidence for the corporate culture theory, which considers that tax payments and CSR/ESG activities are complements, or for the risk manageme

Real time estimations of kLa and viscosity in a fermentation pilot plant

Fermentation is a process that utilizes live microorganisms to produce different biological products such as enzymes. The oxygen mass transfer rate is often the limiting factor in aerobic fermentations and thereby an important process parameter. The initial aim of this MSc thesis was therefore to develop a soft sensor for the volumetric oxygen mass transfer coefficient, kLa, in order to monitor it

“We realised that we are always into hunger when we don’t grow pearl millet” - Exploring decision-making by smallholder farmers and the situation for traditional small grain cropping using Political Ecology in the semi-arid regions of Zimbabwe

Food insecurity in Zimbabwe is severe and increasing. The staple food is made from maize, which is highly sensitive to drought. The traditional small grains; finger millet, pearl millet and sorghum are drought resistant, nutritious and require little inputs compared to maize. Despite this, few farmers grow small grains even though they have been praised as a panacea. This thesis aims to narrow the

Human Factors in Aerial Drone Operations

Meanwhile experiencing an industry-wide lack of regulatory adaptation and official incident/accident data, aerial drone usage is becoming increasingly popular and so the potential safety concern they pose to civil aviation and ‘ground-based objects’. Similarly to the aviation industry, its assumed Human Factors will be a proportionally increasing contributing factor in drone related incidents/acci

Speech activity detection in videos

Speech is an important way of communication all over the world. The speech information is encoded both aural and visual. More than 1.5 billion people have hearing loss and for those the visual information is even more important than for people with normal hearing. Lip reading is therefore an important research topic. In this master thesis, machine learning algorithms were used to identify speech a

Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

Radarsensor som pulsmätare I dagens samhälle används EKG, pulsoximeter samt klockor för att mäta puls på en människa. Vad de alla har gemensamt är att de kräver kontakt med huden, vilket inte alltid är optimalt. Tidigare forskning har visat att det finns potential att använda radarteknik till att mäta puls på avstånd. Detta examensarbete handlar därför om att mäta pulsen på avstånd med hjälp av eHeart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. The aim of this thesis is to investigate how to extract the heart rate with a 60 GHz pulsed coh

Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC). Tetra Pak® has been interested in resear

Artificial Intelligence and Gender Equality: A Study on Legal Scholars’ Understanding of Gender Discrimination and Suggested Solutions

Syftet med denna uppsats är att identifiera den rådande diskursen inom juridisk forskning på området artificiell intelligens (AI) och genus, och att diskutera för- och nackdelar med de lösningar forskare presenterat i relation till substantiell jämställdhet. De rekommenderade lösningarna identifieras genom en systematisk juridisk litteraturgenomgång av AI och genus. Genom att tillämpa teorin om soThe thesis aims to identify the dominant narrative within the legal research field of Artificial Intelligence (AI) and discuss the merit of the prevalent solutions offered by scholars in relation to substantive gender equality. The thesis finds the solutions from a systematic legal literature review covering AI and gender. It develops an analytical framework by applying the theory of social change

Den unika positionen: En dokumentstudie om peer supporterns roll och identitet inom svensk psykiatri

The aim of this study was to explore peer support and their role in Swedish mental health care as described by the user organization and the health care management. A document analysis of official documents produced by the previously mentioned stakeholders was performed applying organizational theory, role theory as well as professional identity theory. The present study found that the peer suppor

Restrictions on Reproductive Health Care and Women’s Labor Market Outcomes: Evidence from the United States

This paper evaluates the impact of reproductive health care restrictions on women’s labor market outcomes in the United States. We exploit the variation in restrictions on reproductive health care services across U.S. states and over time by using individual level data on fertility and labor market outcomes and state level data on reproductive health care restrictions. We apply a difference-in-dif

Ursprungsmärkning av el: en kartläggning av svenska elhandelsföretag

En informativ ursprungsmärkning av el? Vet du vad cirkeldiagrammet som de flesta svenska elkunder får på sin elhandelsfaktura betyder? Har du tagit del av informationen som redovisas i den? Har du förstått informationens innebörd? Om svaret är nej på dessa frågor är du förmodligen inte ensam. Denna studie har kartlagt denna information som finns på elhandelsfakturor, så-kallad ursprungsmärkning aArticle 3(6) of the European Union Directive 2003/54/EC, enshrined in Swedish law through the electricity law (Ellag, SFS 1997:857), lays down the requirement of electricity disclosure. Electricity suppliers are to provide consumers with information about the origin of their electricity and its environmental impacts. The law as well as additional recommendations by the responsible authority, Energ

Investigation of Bio-based Substitutes in a Nitrile-Butadiene/Epichlorohydrin Rubber Compound

En undersökning av biobaserade råvaror i en gummiprodukt som används i bilindustrin Gummiindustrin strävar efter att tillverka fler hållbara produkter för att jobba för samhällets miljömål.
