This research paper aims to identify the most effective algorithms for predicting electricity prices in the German day-ahead market, with a specific emphasis on how renewable energy sources, particularly wind and solar, influence hourly price pro- files. These profiles, or characteristic patterns, depict how prices fluctuate within a day. Different machine learning regression models and methods ar
Denna masteruppsats undersökte potentialen i att använda biobaserade akrylatmonomerer för att producera mer hållbara vattenbaserade golvlacker jämfört med de petroleumbaserade monomerer som nuvarande används. Dispersioner skapades genom emulsionspolymerisation och formulerades med koalecenter och vätningsmedel för att bilda lacker vid rumstemperatur. Den främsta utmaningen med biobaserade monoThis master thesis investigates the potential of using biobased acrylic monomers to produce more sustainable waterborne floor coatings compared to the petroleum-based monomers currently in use. Dispersions were created through emulsion polymerization and formulated with coalescent and a wetting agent to form films at room temperature. The primary challenge with biobased monomers is their highe
This study investigates preschool staff's experiences assessing the need for a report of concern, their knowledge of legislation and signs of child maltreatment, and their collaboration with social services. By examining these aspects, the study aims to identify obstacles and opportunities for improving collaboration between preschools and social services. Qualitative, semi-structured intervie
Syfte: Denna studie syftar till att fördjupa förståelsen för hur konsumenter påverkas av prisnedsättningar inom dagligvaruhandeln genom att analysera hur olika nivåer av prisnedsättningar påverkar sannolikheten att vilja köpa en vara. Frågeställning: Hur påverkar rabattens storlek konsumenternas attityder och köpbeslut inom dagligvaruhandeln? Metod: Studiens metodik är deduktiv och datainsam
This study aimed to investigate how health social workers who work in children and adolescent psychiatry relate to evidence-based methods. The research questions concerned how health social workers understand the concept of evidence-based practices and what opportunities and limitations they perceive with evidence-based methods in their work. A qualitative approach consisting of seven semi-structu
Background and Objectives: Volunteering is characterised by an obligation-free action that occurs typically in an organisational setting. Its goals are to improve the health and well-being of others. Volunteering has the possibility of increasing both mental and physical health of volunteers. Values are the guiding motivators to applying for volunteering activities. The thesis aimed to understand
The purpose of this study was to investigate the discourses regarding disability in eligibility group 1 § 3 LSS in rulings by the Supreme Administrative Court. A critical discourse analysis according to Norman Fairclough’s model was used. The study found that there were three overarching discourses which were: disability as a bodily problem; disability as an expert assessment; and disability as an
Detta examensarbete genomfördes i samarbete med Ekbacken Studios, ett företag som är specialiserat på tillverkning av hemmöbler tillverkade med 3D-printning av återvunnen plast. Begäran från företaget att lägga till hallmöbler till sin produktlinje resulterade i projektets omfattning. För att möta denna begäran genomfördes ett examensarbete för att utveckla ett koncept för hallmöbler, med särskild
Visualization of the molecular and morphological complexity of organs can be achieved through advanced imaging techniques. Imaging has increased our understanding of disease, pathology, and mechanisms. Classic 2D-imaging modalities provide detailed information at a microscopic scale and while valuable, it lacks the ability to explore the spatial resolution of disease mechanisms such as the locatio
The impact prostitution has on women's lives is complex and seldom positive. The purpose of this study is to broaden the knowledge of how women's identities are affected by prostitution. We have studied the life stories of four former prostitutes and their experiences from prostitution. The empirical data was collected from the women's autobiographies. Through narrative analysis of the
Sports have been shown to influence and shape humans in many ways. However, how sports background influences decision-making in early stage entrepreneurial ventures has not been examined closely. Hence, this thesis addressed this gap and explored how sports backgrounds influence decision-making in early-stage ventures. More specifically, it delved into how experience as an elite team sports athlet
This thesis investigates the impact that ESG-ratings have on valuation uncertainty. Because of the increased importance of sustainable investing, understanding the potential effect of a sustainability metric like ESG-ratings becomes increasingly important. This thesis uses an accounting-based valuation model to determine the valuation uncertainty. Using data from multiple ESG rating agencies a new
To sustain a good environment, it is crucial for businesses to be aware of the environmental laws and regulations. However, many smaller businesses and actors may struggle to comply with the complex regulations, which can lead to potential environmental harm. The aim of this study is to investigate the handling of hazardous waste by smaller businesses and if they have necessary knowledge about the
In the past decades different disciplines approached the study of media representation of immigrants. Within this field, the goal of this thesis is to examine the portrayal of Albanian immigrants in the newspaper La Repubblica during the first big arrival in March 1991. Drawing on Critical Discourse Analysis, and with the support of theories such as Social Representation, Othering, Politics of Bel
Detta examensarbete syftar till att utveckla en enkel mätmetod av flyktiga organiska föreningar (VOC) som frigörs från bitumen, en kritisk komponent i tillverkning av asfalt. Med tanke på att bitumen är en råoljeprodukt, särskilt vid uppvärmningen, är det viktigt att noggrant övervaka och kontrollera dess emissioner under bearbetning för att säkerställa en hållbar resurshantering. I detta arbete
Kombucha contains a plethora of compounds that contribute to its health benefits apart from its probiotic effects. This project was conducted to determine the total polyphenolic content (TPC) and total antioxidant content (TAC) of kombucha prepared with black tea, oolong tea, and green tea as a function of fermentation time (day 0 to day 18). Amongst all the kombucha samples, green tea kombucha on
This thesis explores the connection between gender identity and experiences of elections within the Italian sociopolitical context, focusing on the realities of trans* and gender non-conforming individuals. It investigates the implications of electoral procedures that reinforce essentialist, binary gender norms, particularly building them on separating Italian voters into male and female lines, as
This research is part of a larger project exploring the use of surface modified microcarriers, specifically polystyrene and PDMS, as a chromatographic medium to enable high resolution liquid state NMR-analysis of biological samples such as blood and plasma. The purpose of the microcarriers is to bind proteins and lipids, which distorts the NMR-spectrum, hence enabling identification of metabolites
Ongoing fermentation in kefir can lead to packaging issues like bulging packages and changes in sensory properties, potentially affecting consumer acceptance. Effective packaging is essential to address these problems and maintain product quality throughout its shelf life. This study aims to investigate the interaction between various packaging types and kefir products over their shelf life. It ex
Disks around single white dwarfs have been observed as infrared excesses since 1987. Over time, these excesses have shown variability, leading to the conclusion that these debris disks undergo changes. However, the infrared excess should not be the only detectable signature from these disks. They are also expected to reflect visible light, a phenomenon yet to be studied for white dwarf debris disk
