The aim of this study was to deepen the understanding of how community-based water management approaches facilitate sustainable and collective action (SCA) in the context of increasing water insecurity in Costa Rica. Applying a qualitative approach, based on fieldwork in Guanacaste, Costa Rica, including semi-structured interviews and a digital community survey, the study uncovers facilitating fac
BorgWarner continuously improves the performance of their friction system, and by that also need more sophisticated measurement methods. The friction system is developed to minimize noises caused by vibrations to improve customer satisfaction. However, studies from BorgWarner show that in some specific drivetrain operations, vibrations can be induced from the friction discs (lamellas) caused by st

Clinical 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
In the mountainous regions of Bhutan and Nepal, post-harvest losses cause significant challenges for producers. Open air sun drying is usually used by farmers to preserve their produce. There are many disadvantages to this method. The Swedish Research Council is supporting a project called Solar Food: Reducing Post-Harvest Losses Through Improved Solar Drying, which aims to create a low-cost solar
Denna studie syftar till att undersöka hur cancelleringsprocesser ser ut i samband med skandaler för influencers och hur de utvecklas under tidens gång. Detta görs i form av en fallstudie, närmre specifikt skandalfallet med Margaux Dietz som inträffade år 2022. För att kunna dra vetenskapliga slutsatser baserat på empiri som följer narrativet, tar rapporten fäste i två teoretiska utgångspunkter - This study aims to investigate the dynamics of cancellation processes in relation to scandals involving influencers and how they evolve over time. It is conducted through a case study, specifically focusing on the scandal involving Margaux Dietz that occurred in 2022. In order to draw scientific conclusions based on empirical evidence that aligns with the narrative, the report adopts two theoretic
How can passionate love and burning hatred exist within the same social context, and how can fellowship and belongingness lead to violence between supporters? This study identified a lack of academic knowledge regarding a supporter perspective on the connection between fellowship within supporter culture and soccer related violence. Thus the purpose of this study was to explore why some supporters
The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. The material model that is to be evaluated is used in the simulation and a specimen of the corresponding material in the ph
In recent years, battery energy storage systems (BESS) have gained prominence as a key technology enabling much needed electricity grid flexibility while simultaneously providing distinct value to its end-users. With the anticipated increase of residual value holding used batteries from mobility applications entering the market, more and more companies are looking to construct BESS offers around t
This master thesis aims to investigate the positioning accuracy improvements of device localization by the implementation of AI/ML functionalities. In this project, we use the fifth-generation(5G) New Radio (NR) system and focus on indoor factories. This setup held under study is a relevant scenario for the Industrial Internet of Things within the industrial sector (IIoT), as the specific characte
High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical app
This thesis examines the strategies adopted and the challenges professionals face while providing cognitively disabled youths with sexual education. The study was conducted via qualitative interviews of professionals working with cognitively disabled youth, ranging between teachers, youth club workers, and sexual health educators. The thesis’ chief findings showed that professionals adopted the st
Bakgrund: Forskning har visat på vinster för patienter som urtränas från ventilator med protokoll, då vårdtiden i ventilator minskar markant vid användning av protokoll. Detta till trots är det mindre än hälften av intensivvårdsavdelningarna i Sverige som använder sig av protokoll vid urträning ur ventilator. Syfte: Belysa barriärer för användning av standardiserade urträningsprotokoll för patient
Kenya stands at the forefront of Eastern Africa’s economic growth, showcasing potential driven by a robust economy, a vast market, and commendable progress in education and infrastructure. Central to Kenya’s transformative agenda is Vision 2030, a blueprint to accelerate the country into a newly industrialized, middle-income country by 2030. However, the country’s industrial experience is often ov
Predicting click-through rates (CTR) is essential for optimizing the effectiveness of mobile advertising campaigns, where accurate prediction of user interactions can significantly enhance revenue generation and ad targeting strategies. This thesis investigates the efficacy of different predictive models, using a dataset composed of impressions and interactions with mobile ads. The models examined
Food security and environmental sustainability are increasingly threatened by the current degradative practices of the agri-food industry. To mitigate the adverse environmental impacts of the agri-food supply chain, the circular food economy has been proposed as a strategy to enhance biodiversity, improve access to nutritious foods and reduce the industry’s greenhouse gas emissions. However, progr
This thesis will be an investigation into different proofs of Completeness in first-order logic. Particular attention will be put on analyzing the role of the Ultrafilter Lemma and its necessity in proving the Completeness Theorem. An attempt will be made to develop a proof that separates out this non-constructive aspect, but still uses the law of excluded middle. The overall aim is to understand
This thesis aims to explore the issue of trademark squatting and its solutions in the EU and China. Trademark squatting is a form of trademark infringement that occurs when individuals or entities register trademarks in territories where they do not have legitimate business operations, taking advantage of the "first-to-file" systems. If trademark squatting is permitted to persist, it has
A distinguishing component of the mortgage bond market in Denmark is the option to prepay a loan before its maturity date. From the debtors perspective, this is often done with the purpose of refinancing to a lower lending rate. Thus, interest rate modelling becomes a natural part of the pricing process of Danish callable mortgage bonds. Today, yield curves are modelled and thought of differently
