Upptäckten av röntgenstrålning har varit betydelsefull för vetenskaplig innovation. Den har använts inom sjukvården för att undersöka olika kroppsvävnader, men har också haft en inverkan inom biologi och materialvetenskap genom olika experimentella metoder. Röntgenstrålning består av elektromagnetiska vågor precis som det synliga ljuset vi ser från solen. Till skillnad från synligt ljus har röntgeBragg Coherent Diffraction Imaging (Bragg CDI) is an X-ray imaging technique used to recover the internal strain information of nano-scale crystalline particles. A particle, illuminated by X-ray beams, is rocked along a direction θ and the entire diffraction volume is sampled by a series of 2-D diffraction patterns. From the diffraction volume, the internal structure of the particle can be recover

Miljöförändringar är framträdande i den samhälleliga debatten där sådana förändringar ses som ett växande hot mot diverse samhällsstrukturer. Detta hot har följts av regleringar inom EU med målet att uppnå nettonollutsläpp till år 2050. För att möjliggöra ett nettonoll-skifte riktas uppmärksamhet mot marknadsorganisationer och deras hållbarhetsarbete. Syftet med denna studie är att undersöka miljö

Föreställ dig att inga fler människor ska behöva dö av cancer. Det låter som en utopi, men med hjälp av ny teknik kommer diagnosticering och behandling av cancer att förbättras avsevärt och fler människor kunna hjälpas. Redan nu klarar maskininlärning av att diagnostisera bröstcancer med större träffsäkerhet än vad erfarna radiologer kan. Det är inte bara bröstcancervården som kommer kunna dra nytDue to the increasing incidence rates of skin cancer, there is an urgent need for novel technologies that can improve diagnostic accuracy and patient outlook. In a previous study, a machine learning model was developed to automatically delineate skin tumours from non-invasive hyperspectral images. However, the reliability of the model was undermined by difficulties with a preprocessing step in whi

The study explores possible determinants of fertility in Costa Rica, in the context of a fertility decline between 2010 and 2024, using a double hurdle model. The research considers household, female, and male characteristics, as well as intra-household bargaining dynamics. Key findings include a consistent negative effect of income on fertility, supporting the quantity-quality trade-off theory. E

This essay analyzes frequently used adjectives co-occurring with general gender-specific nouns and investigates the sociolinguistic effects that the semantic associations and gender-stereotypical descriptions in sentences have on English speakers. A mixed-methods approach was conducted, with one corpus-based, and one empirical methodology used. Previous researchers have studied gender stereotypes’

Syftet med uppsatsen “priset för säkerhet” har varit att undersöka hur remissinstanserna i förfarandet om säkerhetszonerna resonerar kring mänskliga rättigheter i sina remissvar för att få förståelse för vilka intressen de värdesätter. För att uppnå detta har en deskriptiv argumentationsanalys inspirerad av Arne Næss teknik pro et contra dicere genomförts på de remissvar som lämnades in för promemThe purpose of the thesis “The Price for Security” has been to examine how the referral bodies in the legislative process concerning security zones reason about human rights in the responses, in order to gain understanding of which interests they value. To achieve this, a descriptive analysis of arguments has been conducted based on the consultations responses submitted regarding the memorandum wi

Hårdare krav ställs idag på ljudmiljön i kontor där bland annat minskad överhörning mellan kontorsdelar och bättre rumsakustik i mötesrum eftersträvas. Att åtgärda dessa problem blir ofta aktuellt vid inflyttning av nya hyresgäster- en process som vanligtvis innebär omfattande rivningsarbeten och nybyggnation av icke-bärande innerväggar. Syftet med projektet var att ta fram en metod för att förbä

Thesis purpose: The purpose of this study is to examine the extent to which perceptions of the brand name “Barndiabetesfonden” influence donation willingness among adults who are directly or indirectly affected by type 1 diabetes. Theoretical perspective: This study builds on the Theory of Planned Behavior, incorporating an additional variable called perception of brand name. Methodology: The s

This study investigates how digital innovation influences green technology innovation (GTI) in China, using provincial panel data from 2011 to 2023. It explores three transmission mechanisms—technology diffusion, R&D, and policy support—and further examines GTI’s downstream effects on economic growth and employment. The analysis reveals a complex, partially nonlinear relationship, with regiona

This thesis examines Swedish bilateral imports between 1860 to 1913 to assess Sweden’s 1888 shift from free trade to protectionism on Swedish bilateral imports while also exploring the Swedish Norwegian free trade agreement known as Mellanrikslagen during this period. This is approached using Difference in Differences and an event study within a gravity framework. The gravity methodology is co

Användningen av artificiell intelligens har exploderat under de senaste fem åren. Artificiell intelligens kan utvecklas på flera sätt. Ett av de vanligaste sätten är att använda ett neuralt nätverk, vilket kan liknas vid en digital hjärna. För att förstå hur ett neuralt nätverk fungerar kan följande tankeexperiment användas. Föreställ dig att du försöker lära en robot att åka skidor. I början harS-Rprop is an extension of resilient backpropagation (Rprop), which introduces mini-batch learning to the Rprop algorithm. This is done by using two different mini-batch sizes, one for the learning rate and one for the weight updates, allowing for an accurate learning-rate update whilst gaining the fast weight updates of the stochastic gradient descent (SGD) optimizer. In this paper, the concept o

Through the literature on self in the digital sphere, there has been a large focus on vocal consumption and the expressiveness of consumers, hence, there is minimal knowledge concerning how silent consumption can influence the self. Therefore, the purpose of this study is to explore and understand how the consumer uses social media and silent consumption, which we define as consumption and interac

The purpose of this thesis is to explore how consumers perceive and interpret limited-edition clothing merchandise released by fast-moving consumer goods (FMCG) brands as a far brand extension strategy, and whether it influences the parent brand image. The study uses the Swedish FMCG brand Eldorado as a single case to examine how limited-edition clothing merchandise, incorporating recognizable bra

Taphonomy is the study of how different processes have affected the osteological material, from the death of the animal and forward. The purpose of the analysis is to study how taphonomic processes and fluvial activity affect the preservation of osteological material in a wetland environment, by examining the zooarchaeological material from Röekillorna Spring (Löderup parish, Scania). A quantitati

I use the full count data of census year 1910 to examine the intermarriage determinants in Swedish immigrants and the consequences to those who were married to natives compared to their counterparts in endogamy. The results from intermarriage determinants were in line with prior research in general. The results showed that immigrants in exogamy with natives wouldn’t have a high probability o

This report explores the role of local actors in enhancing early warning systems (EWS) for fires in the Eastern Cape province of South Africa. Veld and urban fires present significant risks to communities and infrastructure, especially in rural and informal urban areas. The study focuses on (1) understanding how local actors such as fire services and Fire Protection Associations contribute to the

This thesis explores how entrepreneurs experience and regulate fluctuations in passion, and how these affect their decision-making in high-stakes contexts. While entrepreneurial passion has been widely recognised as a motivating force, little is known about how its intensity fluctuates over time and how such shifts influence strategic behaviour and decisions. Drawing on emotion regulation theory,

Med den rådande klimatkrisen står vi mitt i en stor omställning. EU:s mål om ett klimatneutralt Europa till 2050 innebär att kraftiga minskningar i utsläpp måste ske. Transportsektorn är särskilt viktig, eftersom den står för ungefär en tredjedel av Sveriges växthusgasutsläpp och är idag nästan uteslutande beroende av fossila bränslen. Detta är inte helt enkelt, transportsektorn är oflexibel och iThis master’s thesis investigates deoxygenation strategies for biomass-derived pyrolysis oil (PO). The study focuses on industrial scalability, economic feasibility, and compatibility with existing refinery infrastructure. It was conducted in collaboration with Preem AB, aligning with their renewable fuel initiatives. The high oxygen content and instability of PO present challenges when integrated
