This study aims to discourage error-prone intuitive thinking in decision-making for proactive adaptation to disaster risk and climate change and to encourage the realisation of well-founded proactive adaptation measures by developing a decision support tool for Swedish municipal preparedness coordinators. Using a design research methodology, the researchers interviewed preparedness coordinators fr

Understanding the morphological evolution of galaxies requires efficient and accu- rate classification methods, particularly in large-scale simulations and observations. This thesis presents a deep learning approach for the automated morphological classification of Large Magellanic Cloud-like galaxies, using high-resolution N-body simulations from the KRATOS suite. The study focuses on detecting s

Title: Exploring the scope of optimizing the supply chain network - A case study on an Indian automotive company Author: Arvind Vikram Devendran Supervisor: Louise Bildsten - senior lecturer at the division of engineering logistics & program director of logistics and supply chain management Purpose: The purpose of this thesis is to investigate and propose an optimal solution for the current su

The increased awareness of the importance of sustainability has paved the way for a more climate friendly future. But at the same time, biodiversity is at risk due to overstraining practices used by forest and textile industries. Do we have to choose one or the other when ensuring a greener course of action? In this project, the aim has been to explore what can be done when combining only leftove

This thesis investigates the feasibility and performance of implementing attention-based machine learning models for high-precision cellular localization on low-power hardware. While such models, particularly those using the self-attention mechanism, have demonstrated impressive accuracy in extracting spatial information from wireless signals, they typically rely on GPU acceleration, limiting thei

Automated servo systems are widely used in today’s industry. Therefore, there is high value in improving the reliability and accuracy of these systems and reducing costs. One way to achieve this is to remove the gearbox component, since it typically represents a large fraction of the system’s cost, and it contains many moving parts which will wear and eventually fail. However, removing the gearbox

This project investigates non-planar 3D printing techniques using a robotic system and Polylactic Acid (PLA) filament, drawing inspiration from the spider web’s structure. The primary aim is to develop methods that optimise material usage while maximising print coverage over large areas. Ultimately, the research seeks to expand the capabilities of robotic manufacturing and uncover new architectura

Svartmunnad smörbult: En besvärlig middag Svartmunnad smörbult (Neogobius melanostomus) är en bottenlevande fisk som har tagit sig till Östersjön och är klassad som en invasiv art. Det vill säga att den inte borde finnas här i Östersjön och bidrar till ett försämrat ekosystem! Några av sakerna som den ställer till med är att den ändrar näringsväven i områden där den kommit till, genom att bland a

6G technology is set to revolutionize wireless communication, advancing far beyond speed enhancements to reshape how we interact with technology. A key factor in this evolution is the efficient use of the radio spectrum, particularly in the centimetre-wave (FR3) bands, ranging from 7 GHz to 24 GHz. This thesis investigates strategies for adapting FR2 transceivers to operate in FR3 frequencies thro

Uganda’s higher education system has come under pressure in the past few years. Liberalisation of the education sector attracted numerous private players into higher education provision, and making it commercialised. This has promoted that focus is shifted to the profit motive away from the primary purpose of students attaining gainful employment upon graduation. The research seeks to emphasise th

Understanding the dynamic of a population via either abundance or density is crucial for wildlife conservation. The brown bear (Ursus arctos) is a commonly distributed, yet elusive species, playing a major role in the ecosystem. Usually monitored with genetic sampling, hunted bags, or telemetry data, the use of camera traps for bear monitoring is still to this day a rarely used, yet promising meth

Quantum metrology is a rapidly growing field of quantum information science that aims to exploit the counter-intuitive properties of quantum systems to estimate physical quantities with better-than-classical precision. The field primarily deals with the problem of estimating system parameters, which may or may not directly be associated to an observable. A prominent result of quantum metrology is

German sociologist Hartmut Rosa’s modernity theory of social acceleration argues that acceleration takes place in three arenas. Rosa claims that these are reinforced in a relationship that can not be broken by political interventions. Politics is reactive rather than proactive. With reactive politics the capacity of politics to steer societal development is eroded. The problem of order consists of

The influence of the classic e-servicescape conceptual model in the context of "Flight expert", the first fully functional OTA in Bangladesh has been scarcely explored in existing e-servicescape literature. In addition to this, social factors in e-servicescape conceptual model are another thing that is less studied in social science. The objective of this study was to look into the influ

From Seedlings to Solutions: Which Test Will Sprout Success? Type 1 diabetes (T1D) is a condition in which the body attacks its own cells that produce insulin, a necessary hormone that allows us to use energy from food. People who do not have insulin are unable to process sugar effectively, which causes major health problems. Since there is currently no cure for this condition, affected individua

Metabolism plays a crucial role in an animal’s life as it determines the amount of energy that can be allocated to growth, reproduction, and survival. The strategies an individual adopts to manage its energy budget have direct consequences to its fitness. How an animal allocates its energy will determine whether it can ensure its own survival while having a high reproductive success or neglect one

Motivationsfaktorer för användning av sociala media-tjänster är ett område som det i dagsläget finns begränsat med forskning om. I denna tvärsnittsstudie har syftet varit att utforska samband mellan motivationsfaktorer för användning av sociala media tjänster, problematiskt bruk av sociala media-tjänster, psykiskt mående och livskvalitet. Skillnader mellan de som identifierat sig som kvinnor respeMotivations for social media use is a topic where there is currently a limited amount of research. The purpose of this cross-sectional study was to study correlations between motivations for social media use, problematic use of social media services, mental well-being, and quality of life. Differences between those who identified themselves as women and men were also studied. Data collection was d

The fishing industry is vital for global food security, providing nutrient-rich food, supporting livelihoods, and contributing to economic growth. As the global population continues to grow, it is essential to approach fishing in a sustainable way and preserve marine ecosystems. The United Nations has recognized overfishing as a significant issue. For 2017, it was estimated that about 34% of fish

This thesis contributes to the relatively recent call for a climate-labour turn. This turn positions the alliance building between the climate and labour movements as crucial for developing a strong counter-hegemonic movement with the power to push for a just green transition and confront the forces of capitalism. To understand the conditions and strategies necessary to foster such climate-labour
