Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. Two design of experiment models were then created using Rstudio. The two models had four spec

Denna studie berör incel-män på forumet Flashback och deras livsberättelser utifrån teman om ensamhet, utanförskap, maskulinitet och samhälleliga faktorers roll i problematiken. Tidigare forskning tyder på att ensamhet och utanförskap samt upplevd hopplöshet inför möjligheter till sexuella och/eller romantiska relationer förekommer frekvent inom gruppen incels. Syftet med studien är att utöka kuns

Plastic waste, especially from packaging, keeps increasing. As a consequence, harmful effects on animals and whole ecosystems as well as increasing greenhouse gas emissions can be seen. More sustainable materials are therefore needed, and dry thermopressed cellulose shows promising potential in replacing plastics in several packaging applications. Being a novel type of moulded pulp process, the re

Purpose: The purpose of the study is to gain a deeper understanding of how MaaS business models can be designed and configured. Theoretical Perspective: The theoretical perspective is provided by a preliminary framework which consists of a synthesis between Business model theory and MaaS literature. Methodology: A qualitative single case study was employed with an abductive research approach. E

This essay analyzes multiple speeches by Boris Johnson during his campaign for Brexit and a period after the polls were closed. It examines if Boris Johnson's speeches are characterized and influenced by English nationalism. Furthermore, if his arguments and ideas correspond with the values of nationalism and particularly English values. The referendum of Brexit polarized the United Kingdom. M

Abstract: This essay investigates different causes of homelessness around Europe, as well as how these could be prevented. Reasons to homelessness is a complex and diverse issue that stems from many different causes, both structural and individual. Which this essay will explore by interviewing people that works with homeless individuals to hear their thought on the matter, and then connect that t

Läkemedelstransportering med lipidnanopartiklar (LNP), särskilt svampfas lipidnanopartiklar, har varit intressanta på grund av dess möjlighet att inkapsla läkemedel och överföra läkemedlet genom cellmembranet. Svampfas LNP formuleringen kan påverkas av lipidens molekylära struktur, temperaturen, pH-värdet, utspädningen, bufferten och existerandet av en stabilisator. Projektets syfte var att ersättDrug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. This project aimed

The market for self-help books has rapidly expanded and gained influence over the last couple of years, partially due to social media users increasing the genres status on the book market. This essay will look at three different bestselling books within the genre: Atomic Habits, The Body Keeps the Score, and The Subtle Art of Not Giving a F*ck. It will analyse them using case studies and different

Med ökande koncentrationer av koldixodid i atmosfären är den globala uppvärmningen, samt klimatförändringarna ett kritiskt samhällsproblem. För att minska mängden utsläpp av koldioxid har koldioxidavskiljning presenterats som ett alternativ. Koldioxidavskiljning sker genom att rena avgaser från koldioxid för att sedan lagra det i jordskorpan, eller använda i kemiska processer. När tekniken appliceIn order to limit global warming, bioenergy carbon capture and storage (BECCS) technologies are getting increased attention. To meet emission scenarios, an estimated 4000 carbon capture plants are expected to be required by 2030, indicating that progress in carbon capture and storage (CCS) deployment is currently lagging behind expectation. Therefore novel technologies for carbon capture and stora

The purpose of this essay is to examine and analyze two characters from two different movies, one from the 1950s and one from the 2000s. The primary focus is to analyze how the characters are portrayed and the connection with their performance as dumb blondes. With the three chosen scenes from each movie they will be semiotically analyzed for the purpose of finding signs that can represent the ste

In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. Consideration must be given to whether compromised security is an unavoidable effect of instant payments or if both obj

The accumulation of carbon (C) within boreal forest biomass is an important component of the global carbon cycle. Whilst it is understood that old forests contain a large carbon stock, the continued sequestration of carbon in these forests is debated. Swedish forests today are intensively managed as even-aged monocultures with short rotation times and have historically been managed through selecti

Noise pollution generated by drones has in recent years become a concern for humans and wildlife and has in some regions resulted in regulatory backlash. This thesis investigates the possibilities of developing a low noise drone propeller using computational fluid dynamics (CFD) simulations. A commercial drone propeller from the manufacturer APC Propeller has been modified with different forms of

Syftet med vårt arbete är att identifiera vilka metoder och verktyg som finns kopplade till mental träning samt hur lärare kan använda sig av dessa i musikundervisning. Vår första forskningsfråga handlar om hur mental träning används idag, vilket behov som finns och vilka metoder som används. Vi är intresserade av att ta reda på hur aktiva musiker använder sig av mentala redskap samt ta del av der

The purpose of this study is to contribute with an understanding of what role AI has, and might have, in strategic decision making processes. The literature review of the study builds upon research within Resource Based Theory, Strategic Decision Making Theory and is supported by technical reports on Large Language Models. It is a qualitative single case study with empirical data collected from si

Vi hittar planeter ̈överallt vi tittar i Vintergatan. De ser olika ut var man ̈an kollar. Men det finns några platser där planeter verkar vara obefintliga: i klotformiga stjärnhopar. Dessa innehåller hundratusentals stjärnor som, på grund av gravitation emellan dem, hålls ihop och bildar ett stjärnsystem som sträcker sig över hundratals ljusår i diameter. Än så länge har bara en exoplanet hittats This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. To determine the stellar type, an HR-diagram wa

Syftet med detta arbete var att undersöka olika parametrars betydelse för instabilitetsfenomen i ett underspänt balksystem av limträ. Arbetet syftade även till att undersöka den komplexitet av modellering som krävs för att nå tillräcklig noggrannhet med avseende på instabilitet. Komplexitet i modellering avsåg i detta arbete typ av beräkningsmodell avseende geometrisk representation (1D, 2D, 3D) oFor buildings where high demands are placed on open space, pre-tensioned glulam trusses have become a popular solution. Such a truss is often optimized to be material-efficient when subjected to loading within the plane of the truss itself. However, material-efficient and slender roof trusses can be highly sensitive to loads and unintended movements perpendicular to the loading plane. Poor choices
