This thesis examines how the performance of a rule based trading algorithm, the Golden Cross Trading Algorithm, and an Artificial Neural Network constructed algorithm, the Long Short-Term Memory, perform against each other and a buy- and-hold strategy, when trading on the equity market. The underlying assets will be nine large American tech companies, all listed on Nasdaq. In order to distinguish
Title: The Impact of the Pandemic and War on the State of Global Supply Chains Purpose: The purpose of the thesis is to outline the current state of global supply chains and global energy supply as a result of the Covid-19 pandemic as well as Russia-Ukraine war. Current energy and supply chain issues are explored and discussed based on existing theory on the topic. When the overall issues are cla
Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. If this is the case, dark matter can be produced at accelerators and detected indirectly by searching for missing momentum signals. LDMX will join this se
The use of cancer cell cultures, including immune cells, is essential in cancer research for developing immunotherapies in pre-clinical investigations. However, so far, a large number of animal-derived products are utilised in cell culturing, where experimental variations and reproducibility problems have been reported. Most studies have also only investigated the differentiation of monocytes into
It is difficult to definitively say who the greatest Formula One driver is. It is a subjective assessment and can depend on a variety of factors, including the driver’s skill, their results and accomplishments, their team and car, and the era in which they competed. Some of the most successful and highly regarded Formula One drivers include Michael Schumacher, Ayrton Senna, Lewis Hamilton, Alain P
Zooarchaeological studies have played a crucial role in understanding the pre-historic societies of Scania. The analysis of animal remains from archaeological sites has provided insights into the subsistence strategies, economic practices, and cultural beliefs of the people who lived in the region. Remains from horse, dog, wild boar, and man are commonly observed in offering and burial contexts. D
Aqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. At the site groundwater was previously used as a drinking water source consequently affecting the inhabit
When a fuel cell stack is assembled it is compressed to ensure gas tightness, and as a consequence, the Gas Diffusion Layer (GDL) will intrude into the channels of the Bipolar Plate (BPP). In this work, the GDL is studied in compression tests and through intrusion measurements. Based on the collected data from the measurements, an approximative method is developed to calculate the intruded profile
Att social isolering och ofrivillig ensamhet har negativa effekter på den psykiska och fysiska hälsan är ingen nyhet. Ensamhet är en folksjukdom. Och undersökningar visar att den ofrivilliga ensamheten har starka kopplingar till boendet och det egna hemmet. Tiden under Covid-19-pandemin har präglats hårt av uppmaningen om ”social distansiering”. Ännu mer tid har spenderats i eller i närheten av h
When installing new research equipment at the synchrotron research laboratory MAX IV, a final positional accuracy of tens of microns is usually needed. To obtain that accuracy, initial reference points must be placed within 2 mm from the nominal target points in CAD, in a process referred to as bluelining. It is currently a manual process where points from a virtual environment are transferred to
Ungefär en tredjedel av Sveriges befolkning är friluftsaktiva i skog- och mark minst en gång i veckan. Detta intresse ökar för varje år, och under Covid-19-pandemin nådde andelen friluftsintresserade nya höjder där femtio procent av Sveriges totala befolkning aktivt deltog i utomhusaktiviteter. Men, även fast intresse för utemiljöer och naturupplevelser finns, har alla inte samma möjlighet att ta
In this Master’s thesis, we describe two recent methods aimed at constructing complex-valued harmonic morphisms and p-harmonic functions on Riemannian manifolds. The main tools for these constructions are the common eigenfunctions of the classical Laplace-Beltrami operator τ and the recently introduced conformality operator κ. We then apply the above methods for constructing solutions on the compa
Background: For most patients with end stage renal disease (ESRD) kidney transplantation is the best treatment option. Best outcomes are achieved with living donation. To increase access to living donation for patients who are not compatible with their living donors, Kidney Exchange Programs (KEPs) have evolved. By exchanging donors, compatibility can be achieved thus enabling transplantation.
Vitesklausulen är ett vanligt förekommande avtalsvillkor, särskilt mellan kommersiella parter. Det är inte heller ovanligt att dessa vitesklausuler författas på det engelska språket. Anledningen (eller anledningarna) till varför avtalsparterna väljer engelska som avtalsspråk varierar, och bero-ende på anledningarna varierar också domstolens bedömning av vitesklau-sulen då svensk lag utgör avtalsstClauses stipulating an agreed sum payable upon breach of contract are a common feature in contracts, especially in commercial contracts. For dif-ferent reason(s), such clauses are often written in English. The reason(s) for writing a contract in English may vary but affect how the clause is con-strued under Swedish law. The thesis uses both the legal dogmatic method and the comparative method, whe
Syftet med detta examensarbete är att vidareutveckla en analysmodell inom deformationslokalisering för att få en bredare kunskap om det mekaniska beteendet hos ett geomaterial. Undersökning av lokala egenskaper hos ett jordprov kräver en fullfältsmätnin-gsteknik som i detta arbete är ultraljudstomografi. Anvädning av ultraljudtomografi inom ramarna av geomekanik har med tiden påvisat goda result
The emergence of machine learning based text-to-speech systems have made fully automated customer service voice calls, spoken personal assistants, and the creation of synthetic voices seem well within reach. However, there are still many technical challenges with creating such a system which can generate audio quickly and of high enough quality. One critical component of the typical text-to-speech
Currently, there are no given directives and regulations on how hydrogen refueling stations should be designed in Sweden. A proposal regarding hydrogen refueling stations H2-TSA, is being developed by Energigas Sverige and is expected to be published in 2023. The aim of this thesis is to contribute to development and future revisions of H2-TSA. It is done by analyze how a general hydrogen refuelin
The focus of this thesis is the myths and ideologies inscribed into the aesthetics, narratives and gameplay of post-apocalyptic videogames. The aim is to discuss how the conditions and conventions of the game medium shape what is presented to us as a modern, secular form of apocalypticism. The case studies presented are the two well-known videogames Fallout 4 and The Last Of Us. The research focus
