The safe and just Earth System Boundary for groundwater is transgressed in a quarter of aquifers in Spain, with irrigated agriculture being the largest driver of overexploitation. Guided by the Earth System Boundary Framework, this thesis studies interventions that reversed agricultural groundwater depletion. Through a systematic literature review, five such cases were identified. While aquifer ab
This thesis identifies and evaluates business model alternatives for Oceanbird’s Wing 560 rigid sail, a wind-assisted ship propulsion technology approaching broader commercialisation. The shipping industry’s complex ownership structures create split-incentive problems that complicate investment in fuel-saving technologies, making the choice of business model a strategic decision. Furthermore, the
This thesis investigates the performance and hysteresis behaviour of building-integrated halide perovskite solar modules (BIPV PSCs) under various environmental conditions. With perovskite solar cells emerging as promising third-generation photovoltaic technology due to their high efficiency, scalability, and relatively low production costs, their integration into building surfaces offers signific
The vacuum brazing process was found to have an impact on the corrosion and mechanical properties of the austenitic stainless steel 316L. Although, the effect of heat treatment has been investigated previously, the impact of the nitrogen pressure in the vacuum furnace remains insufficiently understood. Therefore, this study examines two different coils of 316L stainless steel heat treated in three
This thesis explores the possibility of using extended Berkeley Packet Filter (eBPF) to implement inline security enforcement for containerized workloads. The objective is to automatically create profiles for runtime enforcement within cloud environments such as Kubernetes. A key feature of eBPF programs is that they can attach to various different kernel events, similar to the Linux Security Modu
Strategic lawsuits against public participation (SLAPPs) deploy litigation to suppress political rights – especially public participation rights and freedoms of expression, assembly and association. The rights of journalists, human rights defenders, civil society organisations and individuals are chilled by these cases and legal threats, which convert matters of public interest into private disput
The Trigger Scintillator (TS) of the Light Dark Matter eXperiment (LDMX) is responsible for counting the electrons in the incoming beam in order to accurately determine the trigger threshold used in identifying missing momentum events. Electrons are counted by reconstructing their approximately horizontal tracks through the TS. The software algorithm operates on a maximum vertical tolerance value,
In today’s world, the growing use of solar photovoltaic (PV) systems especially in the logistics sector has provided companies with new opportunities to produce renewable energy, improve their sustainability performance, and reduce carbon emissions from their operations. Importantly, the deployment of solar systems also helps contribute to broader environmental goals such as the European Green Dea
Social workers in Swedish child welfare operate within a context where children’s right to express their views is legally regulated, while professional decision-making often takes place in complex situations involving different perspectives and interests. This study aimed to explore how social workers describe their use of professional discretion in cases where children’s and parents’ wishes do no
The assessment of sunlight access in buildings is constrained by methods that rely on simplified point-based evaluation. EN 17037 sunlight exposure evaluates sunlight at a single point on the aperture under restricted temporal conditions. This limits the representation of how sunlight interacts with the aperture over time. These characteristics reduce its applicability at early design stages. The
In recent years, as 6G wireless systems continue to develop, high-accuracy indoor localization has become increasingly important for future wireless systems. At the same time, reliable indoor positioning is needed by many location-aware applications, such as robotic navigation, emergency healthcare, and smart transportation. Since indoor wireless measurements can vary over time due to multipath pr
As offshore wind farms continue to grow in scale and number, wake interaction between turbines represents a significant source of power loss and increased fatigue risk. Consequently, there has been an increased interest in wake control strategies. Wake control strategies aim to mitigate these effects but their comparative effectiveness across power, wake velocity and turbulence intensity is not we
Cybersecurity has never been more relevant than it is today, as attacks become increasingly sophisticated. To keep devices safe from threats, a new type of smart firewall has become an active area of research. This type of firewall can dynami- cally configure itself based on incoming network traffic using reinforcement learn- ing. This research has shown promising results; however, its impact on r
The thesis analyses one of the most debated issues in EU civil procedural law following the adoption of the Representative Actions Directive in 2020. The Directive introduced a harmonised framework for collective redress within the EU, making it possible to bring both collective compensatory and injunctive actions. At the same time, however, it also created important practical and procedural chall
I takt med utvecklingen av AI-genererad media, har allmänhetens uppfattning om sådant innehåll förändrats. Studier visar att innehåll som märks som AI genererat interageras mindre med jämfört med innehåll märkta som mänskligt skapat. Mot denna bakgrund undersöker uppsatsen eventuella metoder för att verifiera att innehåll är skapat av en människa, i synnerhet ifall rätten till namngivelse kan fungWith the rise of AI generated media, a shift in the audience perception of AI generated content has taken place, where studies show that content which is labelled as AI will be less interacted with compared to human labelled content. The thesis therefore examines possible methods for verifying human made content, in particular, whether copyright’s right of attribution can act as a veri-fier for hu
This thesis aims to address a dual crisis. Globally, the construction industry relies on a linear “take-make-dispose” approach and a “tabula rasa” tactic in each novel project, draining the Earth’s resources. Locally, around a half of residential buildings in Riga, Latvia, are of Soviet mass housing typology. These structures are on the verge of structural expiration, at risk of progressive collap
This thesis examines the transport justice in Copenhagen for multimodal transport using cycling and the metro network, to answer the research question ‘How equitable and equal is the bicycle access to high-capacity public transport metro stations in Copenhagen, and how is transport justice distributed?’. This question is answered by combining an expert interview, field observations, and geographic
Trafik spelar en grundläggande och central roll i stadsutvecklingen, där transportsystemet formar hur städer och samhällen utvecklas, människors rörelsemönster och hur miljön upplevs. Tidigare studier visar att det sannolikt finns ca 20 miljoner parkeringsplatser i Sverige. För att minska antalet anordnade parkeringsplatser som krävs vid nybyggnation kan byggherren göra mobilitetsköp som syftar tiTransport plays a fundamental role in urban development, as transport shapes how cities and communities evolve, influence people’s movement patterns and affect how the urban environment is perceived. Previous studies indicate that there are approximately 20 million parking spaces in Sweden. To reduce the number of parking spaces required in new developments, the developer can invest in mobility me
In the algorithmic age, the use of machine learning algorithms to profile individuals and groups is on the rise. European data protection regulation remains focused on an overly individualistic conception of informational privacy, requiring individuals to manage their own data protection. This has been proved unsustainable in practice due to the countless privacy notices that individuals encounter
This thesis focuses on how changing the combustion chamber geometry in a small two-stroke engine can improve performance. The engine used for this thesis is a Husqvarna AB chainsaw engine with Schn¨urle porting and air-leading stratified scavenging. Four different combustion chambers were subjected to CFD simulations, and from them two were selected for engine testing. In total, five combustion ch
