To meet the future demands and growing challenges in operating heat-exchangers at temperatures greater than 600°C, it is crucial to understand the high-temperature oxidation performance of materials for their components. Namely, it is necessary to study oxidation kinetics and elemental composition of the oxide scale to understand how the materials behave and degrade in such extreme conditions. In
A central part for organizations in achieving intended strategies and successfully executing projects is project portfolio management (PPM). However, many companies fail to effectively manage projects related to strategy, and a little research has focused on the realization of PPM regarding organizational development. To gain further understanding of how PPM can contribute to a higher efficiency
Ett flertal studier har undersökt personlighet och kognitiv förmåga i förhållande till livsutfall. Det är däremot färre longitudinella studier som undersökt dessa samband, vilket medför oklarhet i hur mycket individuella skillnader kan förklara livsutfall. Syftet med denna studie var att använda senaste europeiska tvillingdata för att undersöka personlighet och kognitiv förmåga som prediktorer förNumerous studies have examined personality and cognitive ability in relation to life outcomes. However, longitudinal studies examining these relationships are relatively scarce, leaving the extent to which individual differences can account for life outcomes still unclear. The focus of this study was to use the latest European twin data to study personality and cognitive ability as predictors for
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
Background: Purchasing and Supplier Relationship Management are becoming increasingly important as companies’ competitiveness increases. One part of this is Supplier Performance Evaluation (SPE), which is part of the final step in the purchasing process and can be performed in many different ways. SPE can ensure that suppliers are performing as expected and when not, actions can be taken. When mea
The current trends for most fair-skinned populations are that the incidence of melanoma and non-pigmented skin lesions is growing, and this growing trend will continue for the upcoming years. The emergence of deep learning networks and their promising results in solving real-world healthcare problems and improving diagnostic accuracy opens new possibilities. This thesis consists of the creation o
Osteoarthritis (OA) is a heterogeneous inflammatory joint disease that affects around 240-250 million people worldwide. The disease is a prominent cause of disability and a leading source of societal expenses in older adults. As of today, personalized OA treatment is considered essential and is currently being addressed in several osteoarthritis guidelines. To explore the possibilities of precisio
Rheology is a science studying the flow, deformation and fracturing of a material. For a general understanding, this science is utilised to predict how a certain material will behave under certain conditions; in other words, the aim is the characterization of a material. (Wahlkrantz, 2020) This characterization is used to describe the elastic behaviour and the flow behaviour of a material. The ela
The demand for alternative sources of protein has increased; the so-called “protein shift” is an inevitability. Mycoprotein, a foodstuff produced from the mycelium of filamentous fungi, has gained popularity among consumers. Mycoprotein is grown in submerged culture, in either a simple or a complex, undefined medium. Strategies for yield increase in either medium were studied in this paper. For s
Female breast cancer is a complex and heterogeneous disease that accounts for most of the deaths caused by cancer in women worldwide. To stratify breast cancer patients into treatment groups is a challenging task, and in recent years, analysis of the genes active in the tumour has been used in the decision of cancer therapy. Although gene expression analysis is expensive and not available for most
In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
This thesis explores the rationality, completeness and functioning of Safety Management Systems (SMS) amongst micro- and small-sized air operators in business aviation. In the absence of thorough literature in this sector of aviation, a survey of prior research on OHS(MS) and on non-aviation micro/small enterprises (MSE) provided a collection of factors contributing to their safety performance. Us
Over the last decades, the Swedish insurance industry has seen decreased entry barriers due to deregulation and emerging new technologies, which have the potential to disturb the stagnated and consolidated competitive landscape of the industry. Initiated by newcomers like American insurance startup Lemonade, and later Swedish Hedvig among others, there is an increased push toward digitalization, t
Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous malignancy which poses a challenge for treatment efficiency. To better stratify DLBCL patients and optimize treatment protocols, we analyzed the serum proteome using samples from a population-based cohort of DLBCL patients. Our objective was to find association between serum protein expression with clinical parameters such as overall
In the peak of the 2015 refugee crisis, Sweden stipulated a new law in order to give the system respite while recovering from the pressure that followed from the 162 877 asylum applications Sweden received that year. The Act (2016:752) on temporary limitations of the opportunity to be granted residence permit in Sweden entered to force on 19 July 2016 to apply for three years. The law constitution
Title: Exploring Expectations of an Unattended Delivery Service: A Case Study in Sweden Author: Mary Catherine Osman Supervisor: Daniel Hellström Purpose of Paper: The goal of this thesis is to better understand Swedish consumers’ expectations of an unattended delivery box system such as Nowaste’s E-drop. Methodology: This thesis answers its research question through a series of case studies in w
Each year around 3.9 million girls around the world are victims to female genital mutilation/cutting. This custom is often a consequence of traditional, social and cultural norms within a society. In Sweden, female genital mutilation/cutting is illegal and punishable by law, and professionals have obligations to report if there is suspicion that a girl either is, or is at risk of being genitally m
It is necessary for all industries to work actively to minimize their impact on the climate, including the construction industry, which accounts for a significant part of Sweden's total CO_2-emissions. Development to produce concrete and steel with more environmentally friendly processes is ongoing, but to lower emissions immediately and achieve long-term sustainability, we need to develop met
Klimatklivet is an investment subsidy, to support measures that will reduce greenhouse gas emissions. Even though Klimatklivet has contributed to climate investments that is estimated to have reduced Sweden’s emissions by 1.3 million tons of greenhouse gases, the investment subsidy has had to endure criticism. Klimatklivet has been accused of not being a cost-effective policy. The objective of t
Urbanisation has an increasingly negative effect on wild bees and other pollinating insects because it results in land-use change and habitat-loss, leading to population declines. We rely on ecosystem services that bees provide and must ensure their survival. Private gardens constitute a substantial part of green spaces in cities, making them important foraging habitats for pollinators. In 2018 Th
