Dengue is just regular flu but also kills many people all around the world. We all happen to know that dengue viruses have been on the march for the last 100 years. During the late 20th century, it became a serious threat to mankind. Our scientists have been putting their utmost efforts to save people from dengue infections. They have come up with a number of vaccinations and mosquito repellent so

This study aims to gain a deeper understanding of how individuals, in an organizational context, experience the process of unlearning in relation to routines and how these individuals might be influenced in their unlearning process.

Styvhetsförändringar i bröstvävnad är ofta kopplade till en patologisk förändring. Vissa cancertyper som infiltererande duktalt carcinom kan vara åtta gånger så styv som fettvävnaden runt omkring. Genom att komprimera bröstet och mäta trycket på bröstets yta har man identifierat att det blir en lokal förhöjning i tryck där det finns en tumör. Med hjälp av den här typen av mekanisk avbildning av brA change in stiffness of breast tissue is often connected to a pathological change. Some types of breast cancer such as infiltrating ductal carcinoma can be up to eight times stiffer than fat tissue. It has been found that during compression of the breast there will be a local area of relatively high stress at the breast surface at the location of a tumour. This type of mechanical imaging of the b

Optimization is the study of finding the best solution for a problem. The applications of this field ranges from finding the best routes for travelling to finding the ground state of physical systems. This thesis looks at gradient based and gradient-less optimization algorithms which are applied to two problems: the linear least square and the position of a system of springs. The algorithms used a

I mogna industrier prioriteras ofta verkningsgrad och processen snarare än själva produkten. Detta innebär att dessa industrier anpassar sig långsamt när de externa förhållandena skiftar. Exempel på sådan industri är Sveriges köttindustri. Denna präglas av stor klimatpåverkan, även stora mängder matsvinn. Nya teknologier undersökes i nuläget för att skärpa detta svinn; exempel på sådan teknologi äThe competitive landscape mature industries find themselves in tends to make them enforce practices that ruthlessly focus on efficiency and process. This narrow focus makes them slow to adapt to changes in the external environment in which they operate. One such case is the Swedish meat industry. Like many industries, there are downsides involved with meat production and for meat a significant one

För nästan 1800 år sedan levde den grekiska matematikern Diofantos av Alexandria. I hans skrifter är det mycket som skiljer sig från matematik som vi känner den idag; Diofantos använde sig till exempel varken av 0 eller negativa tal i sina uträkningar. Men trots detta påbörjade han studiet av problem som matematiker fortfarande är sysselsatta med. År 1900 presenterade den tyske matematikern David 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.

Förmågan att återskapa förvrängda bilder på ett effektivt sätt har länge varit ett mål inom datorgrafik och bildanalys. I vårt examensarbete, i samarbete med NVIDIA, har vi tittat på ett nytt tillvägagångsätt för detta problem inom maskininlärning och jämfört detta med redan existerande metoder.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

Detta är ett arbete som som syftar till att studera hur djupa eutektiska lösningsmedel påverkar proteinerna bovin serumalbumin och lysozym Ett djupt eutektiskt lösningsmedel är ett lösningsmedel som skapas när två eller fler fasta material, mer specifikt en vätebindningsacceptor (ofta ett kvartärt ammoniumsalt) och en vätebindningsdonator, bildar ett omfattande vätebindningsnätverk. Detta genererThe 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
