The MAX IV synchrotron radiation facility in Lund is designed to produce bright and high-energy X-ray radiation. One important component of achieving this is to keep the electron beam inside the storage rings centered and stable. The aim of this thesis was to develop an MPC (Model Predictive Control) that can accomplish this task more robustly than the currently commissioned I-controller. A contro
This master thesis was performed in collaboration with Orkla Foods Sweden AB. The aim of the study was to investigate rice pudding and how storage time affects the texture properties of the rice grains inside the pudding, and if this could be related to some of the properties of the raw rice. Rice pudding is produced by Orkla Foods under the label Risifrutti and is a popular in-between meal snack
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
This thesis examines the relationship between university education quality and young graduates' labour outcomes. The thesis employs a micro-level data analysis based on the National Survey of Households (ENAHO) and information from the National Board of University Education (SUNEDU). Linear Probability Models and an OLS multivariate regression are used to assess the effects of the quality univ
Bakgrund: Ökad invandring i Sverige har ökat tolkbehovet i vården. Vid avsaknad av tolk används familjemedlemmar och tvåspråkig vårdpersonal som tolkar samt icke-verbal kommunikation, vilket påverkar kommunikation på olika sätt. Syfte: Att belysa betydelsen av tolksituationen inom hälso- och sjukvård avseende samspelet mellan patient, familjemedlemmar och sjuksköterska. Metod: Litteraturstudie med
Barns rätt till en god utemiljö och utevistelse i förskola är inte föremål för tillsyn. Svensk miljölagstiftning är inte tillämpbar för att kontrollera att barn får sina behov av en god utemiljö och en regelbunden utevistelse tillgodosedda enligt rättspraxis. Kommunala miljönämnder runt om i landet har i flera decennier arbetat för att ställa tydliga krav på utemiljön som står till förskolebarnToday, 86% of children between the age of 1 and 5 are enrolled in preschools in Sweden. The outdoor environment is important to support children’s development, health, and wellbeing. Children’s perception of what an appropriate outdoor environment is often differs from what adults consider to be a god and healthy outdoor environment. The aim of this study is to confirm the gap in supervision
Förbättrat ultraljudsprogram, helt utan ultraljudsbilder Med hjälp av ultraljud, nanopartiklar och en magnet finns det ett nytt sätt att se vilken behandling cancerpatienter ska få. För att metoden ska kunna användas i sjukvården så snart som möjligt behöver ultraljudsmaskinen testas med syntetiska ultraljudsbilder. Ett nytt sätt för att se om cancer spridit sig från den ursprungliga tumören tilClinical trials are difficult to access and of high importance when evaluating biomedical software. Without data which is comparable to the intended input data of the final product it is nearly impossible to fully evaluate its function. One way to evaluate ultrasound detection software is the use of phantoms. Another is the creation of synthetic data. In this report one method of creating syntheti
The growing complexity of cloud native applications has necessitated the intro- duction of operators to the container orchestration tools’ suite of components. Operators affords developers the ability to encode domain knowledge and make fine-grained controllers for their Kubernetes clusters, radically extending the range of feasible applications to host. Operators are however vast software entitie
Nu kommer kraven för att återställa naturen – hur ska företagen lösa detta bortprioriterade ämne? Planetens alla livsavgörande funktioner såsom matförsörjning och materialtillgångar är beroende av en välmående natur. Funktioner som just nu håller på att gå förlorade på grund av en global massutrotning av planetens arter. Äntligen börjar makthavare lyfta blicken och inse att det inte bara handlar oBiodiversity is fundamental for human well-being, and we depend on nature’s ecosystem services for our survival. Today, biodiversity loss occurs at an accelerating rate and the number of endangered species is higher than ever. Despite this, biodiversity loss has long been overshadowed by the climate issue. However, the issue of biodiversity is now receiving more attention and new frameworks and po
