Background: Magnetic resonance flow imaging is vital tool for modern cardiovascular medicine. However, it is resource intensive. Simulations can help develop magnetic resonance sequencing methods and can also facilitate use of AI models in the future by providing realistic test models to train on. Simulations of magnetic resonance imaging are often computationally demanding and the accuracy of the

Forskning om tidigare förekomster av kalkbildande nannoplankton är avgörande för att förstå deras roll i dagens klimatförändringar, samt för att kunna fastställa tidpunkten för deras uppkomst. Denna forskning begränsas dock av begränsat bevarande av nannofossil. En proxy för abundans av kalkbildande nannoplankton skulle därför vara användbar. Eftersom kalkbildande nannoplankton är idag de största Research of past calcareous nannoplankton abundances is essential for understanding their role in climate change of today, as well as being able to constrain the timing of their emergence. This research is however limited by preservation issues of nannofossils. A proxy for the abundance of calcareous nannoplankton would thus be useful. As calcareous nannoplankton are the largest producer of calciu

Arbetets syfte är att genom intervjuer ta reda på hur viktigt samverkan och företagsamhet är för alla musiker och kompositörer. Hur hör detta ihop med lyssnande och samverkan i repetitions- eller konsertsalen? Vad tycker dirigenten är viktigt för att driva en orkesterrepetition framåt? Vilken väg ska en kompositör gå för att komma i kontakt med konserthusen? Med intervjuer av kollegor och professoThe aim of the work is to find out through interviews how important collaboration and entrepreneurship are for all musicians and composers. How does this relate to listening and collaboration in the rehearsal or concert hall? What does the conductor think is important to drive an orchestral rehearsal forward? What route should a composer take to get in touch with concert halls? Through interviews

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

This thesis presents the design, fabrication, and characterization of molybdenum–rhenium (MoRe) based MOSFET on InAlAs and InGaAs heterostructures, aiming to integrate superconducting contacts with III–V semiconductors for hybrid quantum compatible devices. The study addresses interfacial challenges that limit contact transparency and investigates different surface preparation and passivation tech

Artificiell intelligens har under de senaste åren fått en allt större betydelse inom hälso- och sjukvården. En framväxande tillämpning är AI-verktyg för journalföring, som automatiserar delar av det administrativa arbetet genom att omvandla tal till text, strukturera anteckningar och i vissa fall föreslå diagnoser eller remisser. Verktygen kan effektivisera vårdpersonalens arbete, men väcker samtiIn recent years, artificial intelligence has gained increasing importance within the healthcare sector. One emerging application is AI medical scribes, which automate parts of administrative work by converting speech to text, structuring clinical notes, and in some cases suggesting diagnoses or referrals. These tools have the potential to improve the efficiency of healthcare professionals, but at

Climate change poses significant challenges, demonstrated by climate threats that are becoming increasingly severe and frequent. This creates a higher need for uncertainty communication that considers risk-based decision-making. Global climate research, synthesised by the Intergovernmental Panel on Climate Change (IPCC), is a starting point for regional climate assessments, for which the Swedish M

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

Quantitative Risk Analysis (QRA) for hazardous materials facilities remains dominated by event tree partitioning into discrete scenarios, with many calculations performed manually. This study formalizes the classical individual and societal risk metrics within the framework of probability theory. The resulting framework enables deeper theoretical inquiry and makes underlying assumptions explicit.

Det kraftigt förändrade omvärldsläget och den nu förändrade miljön som Sveriges armé förväntas agera i ställer allt högre krav på tillgängligheten hos arméns tekniska system. En möjlig lösning för att underlätta planering och genomförande av underhåll är användningen av digitala beslutsstödsystem. Den här studien utforskar vilka funktionaliteter som bör finnas i ett beslutsstödsystem som är anpassThe significantly altered global security environment and the changing operational context in which the Swedish Army is expected to act place increasing demands on the availability of the Army’s technical systems. One possible solution to facilitate the planning and execution of maintenance is the use of digital decision support systems. This study explores which functionalities should be included

Transforming our economy from linear to circular requires new types of businesses in the manufacturing sector, material flows change from global to local. Our cities need to make room for manufacturing again, to repair, upcycle, design, make, resell, and produce local solutions. This presents an urban design challenge, how does a manufacturing area fit in to the climate adapted city needed to redu

This thesis focuses on developing energy barrier models that increase photovoltaic hot carrier extraction efficiency. Hot carriers are electrons containing an excess of kinetic energy and the energy required to leave the valence band. In mitigating losses and increasing the efficiency of solar cells, hot carriers offer the opportunity to extract this kinetic energy. The study of extracting the kin

Mantelplymhypotesen har varit föremål för omfattande debatt under lång tid, ända sedan den publicerades 1971. Denna hypotes förklarar vulkanismens ursprung genom antagandet att ett extremt varmt mantelmaterial stiger upp under litosfären genom smala kanaler. Hypotesen har accepterats av geologer och har använts för att förklara vulkanism på platser som Hawaii och Island. Trots detta har hypotesen The mantle plume hypothesis has been a subject of extensive debate since its initial publication in 1971. This hypothesis posits that volcanism originates from narrow channels of exceptionally hot mantle material rising from the deep mantle to the lithosphere. While some geologists have historically supported this idea, it has encountered significant challenges, particularly in explaining the volc

This thesis investigates everyday misrecognition of Roma flower-sellers in Istanbul’s Ataşehir district, focusing on how they navigate ethnically mixed neighborhoods and workplaces. Drawing on Honneth’s recognition theory, Giles’s critique, and Gramsci’s cultural hegemony, it examines how racialization and normative discrimination shape daily interactions. Based on one month of ethnographic fieldw

Self-supervised learning has become an important approach for machine learning in remote sensing, where large amounts of unlabeled satellite data exist but only lim- ited labeled datasets are available. Contrastive methods such as SimCLR have been adapted to multimodal Sentinel-1 and Sentinel-2 imagery, but current SimCLR-based approaches rely on deterministic embeddings and therefore lack the abi

Denna studie undersökte ungdomars erfarenheter av viktmobbning i en svensk skolkontext, samt hur ungdomar upplever skolans strategier för att hantera viktmobbning och vilka insatser de önskar att skolan hade vidtagit. Eftersom tidigare forskning som fokuserar på själva upplevelsen av viktmobbning är begränsad, gjordes en explorativ kvalitativ studie där en kritisk realistisk position intogs för atThe aim of this study was to investigate adolescents’ experiences of weight- related bullying in a Swedish school context, how they experience the schools’ strategies for weight-related bullying and which actions they wished the schools had taken. Since previous research on the subject is limited, an explorative qualitative study was conducted in which a critical realist position was adopted. The

This thesis addresses a challenge in continuous high performance liquid chromatography (HPLC): ensuring reliable, timely supply of buffer solutions. As biopharmaceutical production increasingly moves toward continuous operation, buffer management becomes critical, since chromatography requires multiple buffer types with precise compositions for washing, elution, equilibration, and regeneration.

Varumärkesrätten är ett område i ständig förändring. Detta är ett direkt resultat av att rättsområdet anpassar sig efter teknikutveckling och idéströmningar i omvärlden. I takt med att immateriella rättigheter får ett allt större värde ökar även incitamenten för andra aktörer att själva dra fördel av etablerade varumärkens renommé eller att bruka liknande varukännetecken på ett sätt som skadar detTrademark law is a legal field in constant change. This is a direct result of its adaptation to technical progress and ideological currents in the world. Intellectual properties are growing increasingly more important as independent assets and entails great values. This development increases the incentives for third party-actors to impermissibly use established brands’ reputation for their own gai
