A large area in statistics and machine learning is cluster analysis. This field of research concerns the design of algorithms that allow computers to automatically categorize a set of observations into different groups in a reasonable way, without any prior information about which observations belongs to which group. It is a part of the larger field of unsupervised learning within machine learning
Several researchers have approached the subject of VUCA and the challenges of operating in a VUCA world. However, previous research seldom addresses specifically how the work can be done or how these qualities and skills can be developed. The purpose of this study is to help professionals responsible for competence development in their work to enable employees to handle a VUCA world. Therefore, th
The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design. While traditionally, methods like methylene blue cell
By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system. The main challenge was the low-temperatur
Syftet med denna uppsats var att genom en tematisk analys skapa en förståelse för ämnet rädsla för brott. Målet var att ge svar på om intervjupersonerna upplevde rädsla för brott, hur rädslan definierades, vilka faktorer som kan ha en påverkan på upplevd rädsla för brott, samt vad denna rädsla kan få för konsekvenser i en persons vardag. För att besvara frågeställningarna har kvalitativa, semistru
Titel: Sampel mellan projektledare och entreprenör Författare: Mohamad Baradey, Semco Baker Handledare: Radhlinah Aulin Examinator: Rikard Sundling Syfte & mål: Studien kommer att undersöka hur samspelet ser ut mellan entreprenören och projektledaren idag. Det kommer även att undersökas om hur samspelet kan förbättras och vilka skillnader i samspelet det finns mellan utförande- och totalen
To evaluate the performance of evaporation systems, performance parameters such as overall heat transfer coefficient and evaporation rate need to be evaluated. These parameters are difficult measure and therefore need to be calculated using other measured data. Alfa Laval Technologies AB have evaporation systems connected to the cloud that record measured data for evaluation. In this degree projec
Existing studies on China’s COVID-19 response have gravitated to a macro-level, formal institutional analysis, focusing either on the effectiveness of the policy in early-stage virus containment or on the growing negative impacts of COVID policy practices on China’s socio-political landscape at the late stage. Using serial interviews accompanied by online observations and documents, this thesis re
Syftet med studien är att undersöka hur material och produkter återbrukas i byggbranschen. Studien har även som avsikt att undersöka vilka hinder som kan uppstå med återbruk av material samt hur projekt lyckas genomföras trots dessa hinder. De metoder som har använts i studien för att besvara frågeställningarna är en litteraturstudie samt en kvalitativ intervjustudie. Intervjustudien genomfördes
Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter. Plotting these stars as [C/O] vs [O/H], it is revealed
Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g., decreasing the amount of chemicals in the process. When producing drinking water, coagulation and flocculation are common processes. Briefly, coagulation is the process when negatively charged organic matter is destabili
Mänskliga attityder är fundamentala för att bevara jordens ekosystem. Denna studie undersökte sambandet mellan mänsklig empati och upplevelsen av samhörighet med naturen, mer specifikt, med specifika växter. Undersökningen baserades på enkäter och den statistiska analysen gjordes med rmANOVA. Deltagarna (N = 106, medelålder =32,7 SD =16,0) bedömde sin empati och upplevelse av samhörighet med naturHuman attitudes toward nature are fundamental for preserving earth’s ecosystems. This study investigated the malleability of human empathy and connectedness to specific plants. We randomly assigned participants (N = 106, Mean age = 32.7, SD = 16.0) to one of three different induction conditions, and measured trait general empathy and connectedness to nature, as well as state empathy and connectedn
Examensarbetets titel: Påverkar betygets riktning kapitalstrukturens resa? En kvantitativ studie om hur eventuella förändringar i kreditbetyg påverkar kapitalstrukturen hos IT- och energibolag Seminariedatum: 01-06-2023 Kurs: FEKH89, Examensarbete i finansiering på kandidatnivå, 15 HP Författare: Anton Åberg, Ella Thygesson, Teo Lindroth Handledare: Anamaria Cociorva Nyckelord: Kapitalstrukt
The immune system is vital to the defense against external and internal threats to our health. Each immune cell subpopulation conducts specialized roles in relation to disease, thus making our understanding and characterization of these cells crucial in screenings, determining disease progression, and developing novel therapeutics. Protein biomarkers discovered through mass spectrometry (MS)-based
Som musiker arbetar jag dagligen med kontrabasen som mitt huvudsakliga instrument. Och jag hade en grundläggande förståelse hur instrumentet fungerade. Men vad är det som gör varje enskilt instrument så unikt i fråga om klang och utformande? I den kommenterande delen av mitt examensarbete redogör jag för mig själv hur mitt huvudinstrument, kontrabasen är uppbyggd genom att själv bygga ett instrumeAs a musician I’m working daily with the contrabass as my main instrument. I had a basic understanding of how the instrument worked. But what makes each individual instrument so unique in terms of sound and design? In the commentary section of my artistic research, I explain to myself how my main instrument, the contrabass is constructed by building one myself from raw material. And with this expe
The primary objective of this study was to validate the Swedish version of the New Sexual Satisfaction Scale-Short form (NSSS-S) in the Swedish population and explore its association with protective psychological factors, including self-compassion, body awareness, and body appreciation. The questionnaire survey method was used in this study, and a sample of Swedish-speaking participants (n = 164)
The aim of this study is to expand on the research body of crisis communication by investigating how an organization can employ crisis communication strategies in navigating a sexual assault crisis. More profoundly, the study used a case study approach with regard to the sexual assault crisis the Swedish television organization Viaplay faced in 2021 in the infamous program, Paradise Hotel. As such
Parental leave policies for fathers are introduced to promote father’s caregiving and gender equality in childcare. Even though the majority of father-friendly policy reforms were led by social democratic parties, a few conservative catch-all parties also proposed policies to promote father’s caregiving. How did conservative catch-all parties frame father’s caregiving when they propose policy refo
The study aims to explore the increasingly relevant and theoretically underexplored field of ridesharing as a solution for first and last-mile transportation, its success factors and challenges, as well as the process of integrating ridesharing into a public transport network. It utilizes a business model innovation framework as the theoretical basis to explore success factors as well as challenge
