In this paper, we outline the construction and the basic properties of the p-adic number fields. Moreover we prove Hensel's lemma and show an application thereof. Lastly we cover symmetric bilinear forms and quadratic forms over general rings, finite fields, the p-adic and rational numbers.
Loss functions are a crucial part of image processing when using modern neural networks, trained with stochastic gradient descent. There exist multiple loss functions today, some claiming to be perceptual. Researchers at NVIDIA recently published a proposal of such a metric called FLIP. This led to our work on this thesis where we present a comparison between multiple loss functions, both establis
While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. The chemical processing limitations for perovskites are laid out and common
The European furniture industry is driven to change from linear to circular business models. Product-service systems (PSS) are considered to offer promising solutions that may enable the transition towards the circular economy. In the furniture industry, one example of a product-service system is the furnishing rental service. However, understanding of how such a service could be developed and imp
The use of deep eutectic solvents (DESs) has a great potential in the pharmaceutical field due to its many advantages such as biocompatibility, low toxicity and biodegradability. Studies have also shown that proteins can be successfully incorporated into DESs. However, protein stability and structure in these solvents need to be investigated for this technology to be applicable. When adding the pr

The rapid globalization has led to a rise in the number of multinational corporations. One common objective among these corporations when expanding to other developed markets is to access intangible resources such as knowledge. Through the acquisition of knowledge, corporations can strengthen their strategic position and improve their competitiveness. When operating across national borders, variou
Extreme heat can lead to a significant increase in mortality, especially for urban citizens. Densification of urban areas can dramatically affect the local climate of the city by replacing green areas with impermeable materials and changing both radiative and turbulent fluxes. The assessment of the thermal comfort in urban areas is an important consideration for local municipalities to mitigate zo
The purpose of this thesis is to study complex analysis, the Bergman space and Korenblum's conjecture. This is done in three parts. In the first part the proofs that the conjecture is true are studied, giving lower bounds of Korenblum's constant. The first proof is explained in detail, to make it as accessible as possible to more people. The main differences for a couple of later proofs th
Riverbed scouring is an emerging problem aligned with higher frequent river discharges, experiences in a short period of time with shifting climate conditions. This problem brings a huge challenge to relevant authorities to safeguard river stability and hydraulic structures. This master thesis study is a preliminary investigation of the local scour problem along a Rönne å river stretch which falls
In recent years, workforce diversity has attracted considerable research attention. However, few attempts have been made to study the perceptions of inclusion and diversity specifically from LGBT+ employees’ perspectives. The aim of this study is therefore to contribute valuable insights into LGBT+ employees’ perceptions of inclusion and diversity at work. The findings intend to develop readers’ u
The purpose of this study is to investigate if there is any relationship between the financial performance of a public company and the gender of its CEO. A total of 379 companies, 264 with male CEO and 115 with female CEO, listed in Sweden between 1997-2020 have been studied. The results indicate that there is no statistically determined relationship between the gender and the abnormal stock retur
The migration issue has been a hot topic for decades. However, internal migration has not received as much attention as international migration. Furthermore, the internal migration pattern can differentiate from ethnicities and nativity status, further impacting their social-economic status. This thesis aims to discover the ethnic differences in internal migration patterns and the differences betw
Social capital is a psychosocial resource that has been found to have a profound effect on well-being and organizational performance. Research on social capital in Sweden is however lacking. The aim of the present thesis was to explore social capital in a Swedish organizational context and how it can be utilized in the new world of work. The thesis is divided into two studies. Study 1 aimed to do
Studiens resultat påvisar ett samband mellan motivationella faktorer, behovsfaktorer och prestation. När motivationella faktorer ger upphov till behovsfaktorerna motiveras en individ och prestationen ökar. Det finns en del motivationella faktorer som leder till motivation och prestation men vilken motivationstyp som ska sporras beror på vilket resultat arbetsgivaren är ute efter. Vidare ligger denThe results of the study shows a relationship between motivational factors, need factors and performance. When motivational factors lead to fulfillment of the need factors motivation and performance increases. There are some motivational factors that lead to motivation and performance but weather you should spur intrinsic or extrinsic motivation depends on the wanted results. Furthermore, the main
Syftet med den här studien är att undersöka vad fenomenet direktare, dvs. då en död person kremeras och kroppen sprids i minneslund utan någon ceremoni, samt övriga förändringar vad gäller riter i samband med död och begravning säger om vår samtid. Undersökningen bygger på semistrukturerade intervjuer med ett antal begravningsentreprenörer, begravningsrådgivare samt krematorievaktmästare verksamma
The objective of this interview study is to examine the discourses on sexual violence that circulate among young cismen in today’s Sweden, in the wake of the metoo movement. This study seeks to understand how ideas of masculinity connect to conceptions of the rapist, and how this relates to the construction of the participants’ own identities. It further aims to explore the emotional dimensions of
The aim of this study was to explore how treatment assistants at a treatment home perceived the identity of the women cared for at the treatment home. The aim was also to explore how treatment assistants perceived the women’s approach to social rules. The method chosen for this study was qualitative interviews with five treatment assistants. The treatment assistants worked with compulsive care at
