With the More Electric Aircraft concept, the aviation industry is moving toward electrification of onboard sub-systems. This transition from mechanical to electrical power places high demands on onboard electrical power generation, requiring systems that can guarantee continuous and safe operation even in the event of a component failure mid-flight. To generate power on a gas turbine driven aircra
Tillförlitlig Hardware-In-the-Loop-testning (HIL-testning) är avgörande för att säkerställa kvaliteten hos elektroniska styrenheter (ECU:er) inom fordonsindustrin. Samtidigt är pålitligheten av testresultaten beroende av att HIL-riggen fungerar korrekt. Fel i riggen kan leda till missvisande resultat, onödig felsökning och ökad utvecklingstid. Syftet med detta examensarbete var att undersöka kriReliable Hardware-In-the-Loop (HIL) testing is essential for ensuring quality and reliability of Electronic Control Units (ECUs) in the automotive industry. However, the validity of test results is strongly dependent on correct operation of the HIL rig itself. Faults within the rig can lead to misleading results, unnecessary troubleshooting times and increased development time. The purpose of thi
Demand for aviation is continuously on the rise, making the modern More Electric Aircraft approach increasingly beneficial. This approach means replacing all subsystems in an aircraft with electrically powered ones, increasing the demand for onboard electrical power generation. This power can be supplied by an electric machine integrated into the turbine of the aircraft, being able to act both as
Electrification is reshaping even the most traditional industrial sectors, pushing long-established mechanical systems toward software-controlled solutions. Assa Abloy launched an electrified overhead sectional door powered by brushless di- rect current (BLDC) motors in 2023, marking a major innovation in its mechanical overhead door segment, decades after the original product introduction. As Ass
Hydrofoner används inom en rad olika industrier och är essentiella för informationsinsamling under vatten. Syftet med detta arbete var att designa och bygga en hydrofon speciellt framtagen för att fånga upp lågfrekvent undervattensljud. Ett huvudfokus var att undersöka automatisk förstärkningskontroll i kombination med den mycket låga gränsfrekvensen på \SI{1}{\Hz}. Arbetet kombinerar litteratursHydrophones are utilized across a wide range of industries and are critical in underwater intelligence. This project aimed to design a hydrophone purpose-built for capturing low-frequency underwater audio. A key focus was the exploration of automatic gain control, particularly in combination with an exceptionally low cutoff frequency of \SI{1}{\Hz}. The work combined literature studies, simulati
Rent dricksvatten och rena vattenmiljöer är ett krav för ett fungerande samhälle och en väsentlighet för att förebygga och behandla sjukdom. Vid optimering av reningsprocessen och dess drift så höjs ständigt kraven på vatten- och avloppsreningsverk, vilket har lett till en process mer och mer övervakad och kontrollerad av datorer. Det tillåter för snabbare justering av processen och pålitligare övClean drinking water and receiving water is a requirement for a prosperous society and is a key element in preventing and treating sickness. In optimizing the treatment processes and operations, requirements for water and wastewater treatment plants are steadily increasing, which has led to the process being supervised and controlled more and more through computers. This allows for faster process
Residential buildings that deploy photovoltaics do not always utilise the total amount of energy they produce. This is because there is a mismatch between PV production and the requirements of the building. This mismatch can sometimes be addressed by deploying a battery storage system. But once storage capacity is exceeded, any remaining surplus is exported to the grid rather than used on site. Th
Biosensors are powerful analytical tools, but their wider application is limited by the natural repertoire of available biological recognition elements. Allosteric transcription factors (aTFs) are attractive scaffolds for expanding this repertoire, but redesigning them to detect novel ligands has historically relied on directed evolution and structure-guided rational design, approaches that are la
Emotions have increasingly been recognized as important to collective action and mobilization in socio-environmental movements. However, less attention has been paid to how movement organizations combine the strategic use of emotions in external communication with the internal management of emotional experiences arising through collective action, and how different contexts shape these processes. T
This thesis examines identity-related drinking norms and therefrom following power dynamics in contemporary Scandinavian young adult narratives. As several studies have indicated, portrayals of alcohol drinking can affect young people’s conception of normative drinking behaviors. Apart from drinking being widely conceived of as a rite of passage and characteristic of youth, certain behaviors are s
Corporate complicity in international crimes falls under the broader category of state-corporate crime, which encompasses the intersection between state and corporate misconduct. The concept of 'corporate complicity' includes both civil and criminal liability and involves various forms of involvement (e.g., direct participation, assistance, facilitation, benefiting, silent approval) and motivation
Australia's social media ban is now in force. It requires platforms to take reasonable steps to stop users under 16 from holding accounts. Drawing on five focus groups with fifteen young people aged 12--16, this paper examines how children understood the ban's effectiveness, impact, and legitimacy as they encountered the platforms charged with enforcing it. Participants widely saw the ban as unfai
Brott och straff är idag en av de viktigaste valfrågorna för många väljare. Under de senaste mandatperioderna har stora förändringar av straffsystemet genomförts och regeringspartierna pratar om ett paradigmskifte i kriminalpolitiken. Vad är det egentligen som förändras? Vilket är det gamla paradigmet som nu ska bytas ut? Var brottsbalken en kompromisslösning som i själva verket gjorde alla missnö
This chapter analyzes how Lundin Oil responded publicly and legally to accusations of complicity in human rights violations connected to its operations in southern Sudan. Since receiving a concession in Block 5A in 1997, the company has faced persistent accusations from civil society organizations. In 2010, the Swedish Prosecution Authority launched a preliminary investigation, and in 2023, two fo
Adrenoleukodystrophy (ALD) is an X-linked recessive disease caused by defects in the ABCD1 gene, leading to the accumulation of very long-chain fatty acids in the nervous system, adrenalglands, blood and other tissues. Male ALD patients may present with either the severe neurologicalphenotype of cerebral ALD, characterized by inflammatory demyelination in the white matter and rapid neurological de
In this thesis machine learning applications to modern particle accelerators are developed and tested at a number of facilities. The focus is on improving and advancing longitudinal diagnostics, with a major project focusing on non-destructive predictions of beam distributions in longitudinal phase space. Applications are developed using data collected from MAX IV, FERMI, SwissFEL and FLASH. Beyon

Totalitarianism has long been a central concept for capturing extremism beyond the left-right scale. While scholars have recognized ideology as indispensable to the totalitarian phenomenon, totalitarianism has predominantly been interpreted in structural terms, leaving the concept of totalitarian ideology underdeveloped. With more recent advances in the theory of ideology presented by Michael Free
