I detta examensarbete utforskas möjligheten att använda så kallade "fully convolutional neural networks" för att utföra semantisk segmentering av epitelvävnad och metaplastisk epitelvävnad i hematoxylin-infärgade lungvävnadsprover. Vidare söker avhandlingen avgöra vilken nätverks-arkitektur som bäst löser detta problem. De arkitekturer som undersöks är ett flertal variationer av nätverkeIn this thesis, we explore the possibility of using fully-convolutional neural networks to semantically segment epithelium and metaplastic epithelium in hematoxylin-stained lung tissue samples. In addition, the thesis aims to find which network architecture is most effective for this task. The networks tested included several variations of the U-net network and various architectures converted to a

That international law progressively recognises and prohibits torture and other forms of ill-treatment in their emergent forms has become widely-accepted in the anti-torture discourse. The premise that torture’s techniques and contexts change is taken to intimately inform juridical recognition, representation and response. Relevant international treaties, such as the UN Convention Against Torture

The market of plant based dairy alternatives such as yoghurt alternatives continues to grow as more information on the environmental impact of traditional dairy products become available. The plant-based yoghurt alternatives come with a new set of problems, including longer fermentation times and poor gel structure formation. The aim of the project was to see if fermented yoghurt alternatives coul

De senaste årens teknologiska utveckling, med sociala medier i spetsen, har stöpt om samtidens medielandskap. En effekt av denna utveckling är att en ny direkthet skapats mellan offentlig person och gemene man. Detta nya förhållande innebär att offentliga personer numera både kan granskas och när skäl föreligger, bojkottas, av allmänheten. Fenomenet har kommit att benämnas som “cancel culture”. Fö

Actio popularis är en talerätt till förmån för någon annan i syfte att skydda ett kollektivt intresse. Principen actio popularis är internationellt kritiserad och är inte erkänd inom internationell rätt. Däremot finns andra verktyg utanför den internationella domstolsprocessen som skyddar kollektiva intressen. Denna uppsats avser att skildra hur actio popularis kan inverka på rätten att föra talanActio popularis is the right to make a judicial claim on behalf of others in protection of a public legal interest. Although actio popularis is criticised and not acknowledged in international law, other forms of protection for public legal interest has been acknowledged outside judicial proceedings. This thesis aims to depict how actio popularis could affect a State’s right to initiate a judicial

The availability of transportation has a great impact on how we move in our everyday lives and on the larger flows of people and goods. Transport planning, then, has the potential to greatly alter levels of mobility and accessibility. Looking at transportation in a cross-border context highlights this potential even further, but also brings additional barriers and points to consider. Examining thi

Studying knowledge-intense regional development from the perspective of classified periphery fills an identified gap in analysis and practice. It illustrates challenges, possibilities, and nuances current trajectory of centre-peripheral development. Exploring role and perspective of peripheral areas within regions, and thus marginalized places, can help increase cohesive, instead of fragmented, re

Enterprise Risk Management is implemented in various sectors and context. What is really know about ERM and how has the concept progressed parallel to risk research in general? This master thesis investigates some general aspects of ERM and what specific aspects of risk management research is present in current scientific literature. The thesis will consist of a scoping study and a practical imple

Denna uppsats undersöker Qatars kritiserade arrangörskap av det kommande världsmästerskapet i fotboll 2022 genom att studera 72 artiklar från Aftonbladet, Dagens Nyheter och Al Jazira. Syftet med studien är undersöka hur mediebilden av mästerskapet sett ut mellan 2010 och 2019. Studien undersöker om det konstrueras en global moral i form av utrymme till ställningstagande och agerande för mänskliga

In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. This study investigates how the confetti behave, defo

Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. In a world with finite resources and growing concerns for the environment the importance and interest in recycling grows larger. This has led the Volvo Trucks Corporation to u

Moral and ethical considerations have always been important in discussions about warfare and the development of the international community and body of international humanitarian law, laws whose fundamental ethics that can be attributed to Just War Theory. With the changing nature of conflicts and due to the lack of internationally declared principles of just and unjust wars, this thesis argues th

We investigate to what degree return on technology stocks are affected by industry-, country- and global factors. Furthermore, the analysis is extended to look deeper into the industry factors by examining what the exposure of technology stocks to industry-specific shocks is caused by. In previous studies, the aim has been to try to determine whether industry-, country- or global effects are the m

This paper examines the properties of the two recent structural break unit root tests developed in Harvey, Leybourne and Taylor (2013) and Narayan and Popp (2010). The properties are investigated by Monte Carlo simulations in an environment where two trend breaks of small to large magnitudes are present. We find that the Harvey, Leybourne and Taylor (2013) test has superior size and power properti

This report presents a mathematical kinetic model describing the recovery of metal ions as metal sulfides, using sulfate reducing bacteria (SRB). Metal recovery from industrial waste is a potential beneficial and unused source of metals. The developed kinetic model is implemented and simulated in the computer programs MATLAB R2014b and Aspen Plus V8.8. The MATLAB simulation is performed on the bio

Antibody microarray is a tool used for protein expression profiling that takes advantage of the high specificity of antibodies. The tool has numerous of potential applications, such as detection of disease biomarkers, but also has some potential limitations that must be considered. Variations in antibody activity between different production batches and altered analyte levels in samples due to imp

Advances in our understanding of hematopoietic stem cells (HSCs) have enabled the establishment of differentiation pathways throughout the hematopoietic hierarchy. To further explore the molecular cues governing cell fate options, there is a need to manipulate gene function in a controllable manner. Gene manipulation systems based on CRISPR activation (CRISPRa) or interference (CRISPRi) could be u

Entrepreneurs in different countries and industries face many obstacles during their journey. It comes down to the entrepreneur to build strategies on how to overcome those obstacles. In this research, we focus on providing an in-depth analysis on the obstacles that Arab-immigrant entrepreneurs face in Sweden and how they overcome them. Immigrant entrepreneurship has had its fair share of research

The primary aim of the study was to investigate the applicability of Dunn’s sensory processing model (1997) to youth with Obsessive-Compulsive Disorder (OCD). The model describes four patterns of sensory processing: sensory sensitivity, sensation avoiding, low registration and sensation seeking. The current study test whether these four processes are related to, and differentiate, OCD from anxiety
