Purpose: The aim of this study was to investigate a new methodology for brachytherapy of oesophageal cancer using magnetic resonance (MR) imaging for treatment planning. That includes finding a suitable oesophageal applicator that can be visualised on MR images and to create dose and fraction schedule that should be used brachytherapy treatments. Material and Methods: A total of six patients were
Connective Boundaries is a personal reflection on how a worthy and comforting funeral ceremony can be designed without religious convictions. It begins with the acknowledgment that, today, the tension between the personal and the social experience of death has led to attempts to sanitize, hide and compartmentalize both the mourner and the deceased, alienating both. This project investigates the
Designing and developing a software product is a difficult process. The product must be usable and solve the correct problem. At the same time, the underlying code must be well written. Many projects fail to deliver or exceed their budget. This thesis explores a practical approach to software design and development that tries to adhere to both user centered design and agile development. The proces
As we’re living in a modern society, most of us have been connected to the water and electricity grid, However, there’re still billions of people who are still lack of reliable water and electricity resource. In some developing countries like India and Philippines, the demand for electricity and water are far more than actual production, which causes frequent electricity and water shortage problem
Japan continuously attempts to reinterpret war-renouncing Article 9 while at the same time stressing its devotion to pacifism, most recently through the Legislation for Peace and Security. The new Legislation allows Japan to engage in collective self-defense, which was considered unconstitutional for 70 years. This thesis examines Japan’s legitimization of such change, answering the question; how
Cross-functional teams and meetings are recurrent structuring tools in contemporary knowledge organisations. They are recommended as solutions to enhance innovation and creativity. Current research gathers a myriad of reference to the benefits of such tools, but studies of their potential negative effects remain limited. This paper is specifically concerned with the effect of interdisciplinary tea
The many-body problem in quantum mechanics always presents new challenges and ways to discover new properties of existing materials. The difficulty (if not the impossibility) to solve the many-body problem analytically makes the numerical methods an appealing approach. Here we consider a Python code, which is under development to become an open-source tool to perform studies of finite lattice syst
In this thesis, a new probabilistic risk assessment tool for road tunnels has been verified and validated. The verification and validation were performed along with a literature review to find different key variables that affect the risk in a road tunnel and find out how these variables can be handled. Examples of variables are heat release, ventilation mode and factors within evacuation modelling
Digitalisering är utan tvekan 2000-talets viktigaste bidragande orsak till utvecklingen av den globala ekonomin. Skatteplanering och skatteflykt bland multinationella bolag urholkar nationers skattebas som finansierar det offentliga välfärdssystemet såsom sjukvård, utbildningsinstitutioner och infrastruktur. Digitala affärsmodeller genererar intäkter annorlunda än traditionella affärsmodeller ocDuring the 21th century, digitalization is considered the most important development of the modern global economy. Tax avoidance is a growing issue for governments globally, that are loosing lots of tax money to finance public welfare systems supporting healthcare, educational institutions and infrastructures. Value creation in digital business models generates profits different than traditional b
According to the United Nations, half of humanity now lives in cities. In recent years, many countries have seen a rise in the number of and intensity of heavy rainfall events due to the effects of climate change. The consequences of urban flooding in such a context can vary between just causing mild discomfort to tremendous devastation. Building cities that can resist flood is quickly becoming an
This paper examines the ambiguous property rights in China and if they affect the private sector development. The indicators for property rights include both broader property rights and intellectual property rights. The property rights theory offers a perspective as a fundamental component of a market economy to enable a growth of private enterprises. The incentives and constraints offered by the
Context: Today, 96% of Sweden’s materials come from virgin resources and only 3.4% of resources used in Sweden are retained in the value chain. From a total of 266 million tonnes fed into the economy each year, 46.9% consist of construction materials. Hence, there is a need to adapt circular strategies, such as reuse of construction products, to meet Sweden’s goal of becoming net zero by the year
Syftet med denna rapport är att utvärdera möjligheten att använda Virtuell Verklighet (VR) som ett medium för användbarhetstestning. Användbarhetstestning är en viktig del av alla iterativa utvecklingsprocesser. Vanligtvis utförs testerna i en laboratoriemiljö utanför produkternas naturliga miljö. Genom att använda VR kan dock användare uppleva testmiljön på ett mer realistiskt sätt. Studien genoThis thesis aims to evaluate the feasibility of using virtual reality as a medium for usability testing. Usability testing has long been an important part of any iterative development process. Most usability testing is, however, done in a lab setting, outside the product's natural environment. Virtual Reality (VR) on the other hand can engross a user in any environment. This thesis was done i
In this thesis, we evaluate the side-channel security of the NIST HQC post-quantum cryptosystem by analysing the official FPGA decapsulation implementation. A hardware wrapper was created to interact with the HQC decapsulation modules, enabling ciphertext decapsulation with precise power trace capturing using a ChipWhisperer CW305 and Husky setup. A dataset with 20k power traces was generated from
As plastic pollution in aquatic environments persists, gaining a deeper understanding of nanoparticles has become increasingly important. Yet, the question remains: what happens to plastic as it breaks down into smaller components, and ultimately, what end products are formed? Current plastic degradation methods are limited in their environmental applicability and efficiency. This study aims to pr
Hybrid detectors, consisting of semiconductor sensors bonded to a readout Application-Specific Integrated Circuits (ASICs), are widely used for single-photon detection in photon science and high-energy physics. The Timepix3 readout chip provides precise Time-over-Threshold (ToT) and Time-of-Arrival (ToA) measurements, making it a valuable tool for sensor characterization. This thesis presents the
This study looked at a fluorocarbon-free water-repellent treatment on different types of polyester textiles in order to test the durability of the treatment in simulated wear-and-tear tests in collaboration with Thule Group. This research was being done in order to gain a deeper understanding in the strengths and limitations of the C0 Water-Repellent (C0WR) treatment on polyester textiles. The stu
This master’s thesis examines similarities and differences in operational work, training, and the use of technology related to Smart Firefighting in Sweden and Hong Kong. Smart Firefighting has been proposed as a response to challenges arising from modern urban development, where data from smart buildings, combined with AI and digital tools, could support fire and rescue services. However, such da
Tendons connect muscle to bone and assist in joint motion. To be able to do this, they must withstand large forces and be able to alter their structure under load. If a tendon experiences too high or sudden forces, it will start to tear and eventually rupture. To examine how this happens and how the tendon behaves before rupture, mechanical testing is done. This study focuses on how to combine mec
