The segmentation and separation of objects in 3D medical imaging, particularly in Computed Tomography (CT), are essential for accurate diagnostics and preoperative planning. This master's thesis presents a tool for the interactive and automatic separation of segmented bones in CT scans, using the Random Walker algorithm and neural networks. The tool was developed to address challenges such as

With increasing environmental awareness, building materials and their impact on the environment are increasingly coming into focus. This study presents a framework for comparing Life Cycle Assessment (LCA) through A1 - A5 stages from the perspective of Global Warming Potential (GWP) to assess the climate change potential of three facade systems of different building types (villas, medium-sized bui

En av de sjukdomar som påverkar flest människor årligen är malaria. Malaria sprids av myggor som bär på parasiten och när de biter en människa överförs parasiten till människan. Vanliga symptom vid en malariainfektion är lätt feber, frossa och huvudvärk. Dessa symptom kan bli allvarligare om personen är gravid, ett barn mindre än fem år gammalt, eller har HIV eller AIDS, eftersom sådana personer tMalaria is a well-known disease and affects large regions around the world. Medicines used for treatment already exist, but due to increasing resistance and unpleasant side effects it has become critical to develop new drug candidates. Several palladium complexes were synthesised and studied to understand their properties for treating malaria. The ligands and the complexes were synthesised and cha

Growing population in Swedish cities and limited natural resources combined with climate change impacts led decision-makers to develop densification strategies in city planning. However, densification could come with several challenges including reduced green spaces, increased urban heat island effect and energy demand, as well as the lack of thermal comfort in buildings. Densification becomes eve

Electrification of the automotive industry calls for high performing electric engines. Since the use of iron from primary sources in the production of engine cores has a high environmental impact, it would be beneficial if they could be made mostly from recycled materials. Soft magnetic composites used as cores in electric engines have lower mechanical strength compared to the alternatives. This i

Denna studie undersökte sambandet mellan altruism, extraversion och motivation. Ett av personlighetsdragen i femfaktorsmodellen är extraversion. Detta personlighetsdrag testades som en möjlig prediktor för altruistiskt beteende. Dessutom undersöktes motivation som en ytterligare faktor bakom altruism. Deltagarna (N = 68) besvarade en enkät från online bestående av tre självskattningsskalor. ExtravThis study examined the relationship between altruism, extraversion, and motivation. One of the personality traits in the five-factor model is extraversion. This personality trait was tested as a potential predictor of altruistic behavior. Additionally, motivation was investigated as another factor contributing to altruism. Participants (N = 68) completed a questionnaire from online consisting of

Känslan av mobilskärmen mot fingertoppen, klickljuden från kollegan som knappar på tangentbordet, skenet från en färgglad televisionsskärm som lyser upp vardagsrummets dunkel ... Den moderna människans tillvaro präglas av hens samspel med informationshanterande elektronik, och förbättringar inom informationsteknik är därmed av stor betydelse för en högre levnadsstandard. Ett sätt att förbättra kom[8]annulene units linked by alternating benzo[a,e]moieties are a promising new design for electro-responsive hydrocarbons. However, current methods for synthesizing benzo[8]annulenes limit the prospect of constructing longer multimers. In this work, an alternative synthesis route to the compound containing two [8]annulene moieties was pursued. The dimeric compound was ultimately furnished over thr

This thesis explores the philosophical and historical perspectives of Ibn Khaldun and Oswald Spengler regarding the cyclical nature of civilizations. By analyzing Ibn Khaldun’s Muqaddimah and his theory of asabiyya (social cohesion), alongside Spengler’s kulturseele (cultural soul) in The Decline of the West, the study examines their respective explanations of the rise and fall of societies. Ibn K

Närvarodetektion som säkerhetssystem Maskinsäkerhet säkerställs ofta med klumpig och hindrande utrustning, vilket kan vara opraktiskt i många sammanhang. Genom att istället trädlöst identifiera och särskilja olika operatörer kan utrustningen avgöra om det är säkert eller ej att starta olika processer på ett smidigare sätt. För att kunna implementera den trådlösa närvarudetektionen som krävs förWireless communication encompasses a wide range of applications, demonstrating its versatility in various domains. For example, it can be utilized to enable access control through the use of tags, act as a deterrent against theft in retail settings, or support global and interstellar communication. What all of the different use cases have in common is that they work by employing radio frequency tr

René Descartes’ Meditations on First Philosophy explores foundational philosophical and theological questions through a method of radical skepticism. Central to this exploration is the concept of the evil demon, a hypothetical being that challenges human capacity to comprehend and perceive reality. Descartes’ meditations are pivotal to the development of rationalist philosophy, bridging epistemolo

Sedan 1700-talet har 87 procent av världens våtmarker försvunnit, med en acceleration under de senaste 50 åren där mer än en tredjedel av världens våtmarker försvunnit på grund av exploatering. Våtmarker bidrar med många viktiga funktioner, såsom klimateglering genom att minska översvämningar och torka samt genom att agera som naturliga reningsverk. I takt med klimatförändringarna har våtmarkers fWetlands play a vital role globally in protecting biodiversity, purifying water, and mitigating floods. In Kigali, Rwanda’s capital, five natural wetlands are located in the city center. This master’s thesis aimed to evaluate the water quality of these wetlands and identify key pollution sources. The aim was also to analyse changes in water quality over time with respect to changes in demographics

På grund av klimatkrisen har det blivit allt viktigare att förändra våra konsumtionsvanor och ta bättre hand om det vi redan har. I arkitekturens kontext innebär detta att vi tar hand om och transformerar de byggnader som redan existerar i våra städer. Dessa byggnader är mer än bara strukturer och material, dem är en del av vår historia och kultur. I stället för att riva de byggnader som inte läng

This thesis is an investigation of sediment transport in the Piura River in Peru. Years of anthropogenic changes have redirected the river towards the south and have caused changes in the flow regimen (Alvarado Ancieta & Ettmer, 2007). It is suspected that the redirection towards the south has resulted in deposition of sediments which has reduced the capacity of the river in the lower reaches

The aim of this thesis is to study whether high retail ownership of a firm impacts the market response to an earnings announcement. To this end, I utilize the traditional event-study methodology in combination with cross-sectional regression. The latter is used to examine whether a company’s ownership structure affects abnormal returns. Two event windows were analyzed, a three-day window and an el

A case study house for a regenerative architecture. What would a regenerative architecture look like, in the context of a wetland landscape? With climate catastrophes becoming the new reality for an increasing amount of communities, floods among them, how would we live in a landscape, and with what materials would we build, in order to mitigate these issues? How do we live with a landscape, inste

E.M. Forster’s Maurice (1971) and Stephen Spender’s The Temple (1988) were written at the beginning of the 20th century and they both portray narratives of what life could look like for men who experienced attraction towards other men at the time. In this essay I examine how homosexuality is represented in Maurice and The Temple, and in what ways the portrayals of homosexuality in the two novels r

In biological observation of small flying animals, structured light methods can be used in order to make high frequency, no contact measurements in flight. Using a laser pointer that projects a 5625 point mesh pattern, as well as two high-speed cameras, three different methods for estimating the shape of 3D objects have been developed and evaluated. The cameras were calibrated, as well as the lase
