Tillsammans med klimatförändringar och omfattande överfiske utgör IUU-fiske (olagligt, orapporterat och oreglerat fiske) ett allvarligt hot mot den marina biodiversiteten globalt. En särskilt drabbad region är Västafrika, där kuststater historiskt har haft rikliga fiskeresurser inom sina exklusiva ekonomiska zoner (EEZ) i Atlanten. Den ökande förekomsten av industriellt fiske, till stor del represExacerbated by climate change and general overfishing, illegal, unreported, and unregulated (IUU) fishing poses a serious threat to marine biodiversity globally. One particularly affected region is West Africa, where coastal States have historically possessed abundant fishing resources within their Exclusive Economic Zones (EEZs) in the Atlantic Ocean. The reliance on industrial-scale fishing, lar

Krediter spelar en central roll i det moderna konsumtionssamhället och möjliggör för konsumenter att finansiera köp som de annars inte skulle ha råd med. Samtidigt medför en överdriven upplåning risker, då konsumenter kan åta sig skulder de inte kan återbetala, vilket kan leda till överskuldsättning. Problemet har både individuella och samhälleliga konsekvenser: individen kan uppleva allvarlig ekoCredit serves as a fundamental pillar of modern consumer-driven economies, empowering individuals to finance substantial purchases that would otherwise be unattainable. However, excessive borrowing carries risks, as consumers may accumulate debts they cannot repay, leading to over-indebtedness. This issue has both personal and societal consequences: individuals may experience severe financial dist

Världen genomgår just nu en omställning inom elproduktionen, från fossila bränslen till mer hållbara alternativ, för att minska växthusgasutsläppen och bekämpa klimatförändringarna. Solceller är en viktig teknik inom denna omställning och fungerar genom att ljus fångas upp av ett material och omvandlas till elektricitet. En sorts teknik inom solcellsbranschen som får mer och mer uppmärksamhet ärTo meet the energy demands during the transition from a fossil fuel-dependent society to one powered by renewable energy, a diverse range of sustainable energy production is needed. Zn3P2 is an earth-abundant photoabsorbing material with great optoelectronic properties for use in sustainable thin film solar cells. So far, progress has been limited by the difficulties of fabricating high-quality, d

As digital transformation continues to expand, the threat landscape for cyber-attacks has become increasingly complex. Proactive detection and prevention of cyber-threats are essential to secure critical infrastructures. This thesis proposes an approach centered on leveraging data analysis and Machine Learning (ML) to analyze and predict the existence of potential cyber-threats. By harnessing the

This master’s thesis was performed at Axis Communications with the goal of exploring the use of Novel View Synthesis (NVS) - in particular, NeRF and Gaussian Splatting - in camera surveillance. This was done by iteratively creating prototypes and performing user testing on these according to the iterative design process. The prototypes were to be developed with existing implementations of NVS tech

För att göra modeller och förutsäga vår omgivning krävs det ofta bakomliggande teorier med empiriska data. Subglacialt sediment har länge varit täckt av glaciärer och oåtkomliga att undersöka. Då glaciärer smälter bort och raviner i glaciärer ger åtkomst till subglaciala sediment finns det nu möjlighet att studera materialet och ta fram empiriska data, samt testa befintliga teorier. De hydrauliska

The aim of this project is to explore the tiled stove as a historical everyday object and examine its potential influence on contemporary design. The project further investigates direct heating using infrared panels. The result is a fusion of tradition and innovation, combining the material and visual qualities of tiled stoves with contemporary heating technology. The final design consists of tw

Kan växtbaserad yoghurt med tillsatta probiotiska bakterier gynna tarmfloran? Tarmfloran har kopplats till både hälsa och sjukdom, och genom att äta probiotiska bakterier hoppas man kunna gynna de goda bakterierna i tarmen, som får oss att må bättre. I den här undersökningen har en växtbaserad och en mjölkbaserad yoghurt med tillsatta probiotiska bakterier ätits i 4 veckor och deras effekt på taIn recent years, the development of meat-and dairy analogues has increased to meet demands from consumers, as well as serving as environmentally beneficial alternatives to meat and dairy. While traditional plant-based diets based on whole-foods have been shown to lead to beneficial health effects, the new analogues differ vastly from the ingredients of a whole foods, plant-based diet and the effec

The thesis examines the role of middle managers in improving safety at a power plant. Through a social constructivist approach, it analyses how middle managers can shape and sustain safety through their communication, attitudes, and actions. The study focuses on the challenges middle managers face in balancing leadership duties, administrative responsibilities, and their own tasks, often at the ex

The planetary boundaries (PBs) framework defines a "safe operating space" based on nine key Earth system processes. Out of these, four are terrestrial, and their primary driver of transgression is agriculture. To better understand how agricultural activities might further influence the terrestrial PBs, it is essential to model their drivers and interactions over time. A helpful tool for

Det finns brister gällande tillgängligheten och delaktigheten för alla när det kommer till den allmänna kollektivtrafiken. Personer med funktionsnedsättning exkluderas på så sätt att de möts av barriärer och hinder som exempelvis stora avstånd mellan hållplatslägen, höjdskillnader och obekväm väntetid. Variationen av barriärer är stora och hur de vidare upplevs och skapar hinder. Trots utförda tiThere are flaws when it comes to accessibility and participation for all people when it comes to public transportation. People with disabilities are sometimes excluded when it comes to dealing with barriers and obstacles, for example large distances between stops, height differences and uncomfortable waiting periods. The variation of barriers, how they are perceived and how much of an obstacle the

This thesis examines the key challenges to blockchain implementation and how these challenges impact the technology’s adoption rate within the Swedish food industry. The focus of the research questions is on identifying these barriers in order to gain a greater understanding of their influence on the industry. The method of this study has a qualitative research approach. It combines primary data i

This study unravels discursive formulations of lobbying and transparency in the aftermath of Qatargate to better understand the relationship between lobbyists, corruption scandals, and transparency frameworks in the European Union. Using Foucault’s interpretive analytics operationalized by CDA and semi-structured interviews with Public Affairs practitioners and MEPs in Brussels, this inquiry argue

The existing Power Supply Unit (PSU) at Axis Communication contains a fully discrete solution that lacks flexibility for future updates. This research aims to address critical challenges by exploring methods to enhance speed, reduce PCB area, and introduce flexibility to the existing hardware solution. The approach involves replacing hardware functionalities within the control unit with software-c

Bumblebees are essential pollinators, sustaining ecosystem balance and aiding crop pollination. A comprehensive understanding of their foraging ecology is therefore crucial. We studied the influence of life-history traits of individual Bombus terrestris on wing wear and its foraging patterns. Wing wear is clearly a widespread phenomenon observed in all flying insects. Wing integrity has consequenc

Gladan i med-och motvind Den röda glada (Milvus milvus) är en rovfågel vars öde sedan länge varit tätt sammanflätat med människan. En kungarnas fågel, kallad Milvus regalis och milan royal, samtidigt ansedd som en smutsig asätare och avskydd kycklingtjuv. Människlig förföljelse drev den närapå till utrotningens rand, varifrån ihärdigt bevarandearbete bringat den åter. Idag är dess karakteristiskaIn a world of rapid biodiversity loss, raptors are vulnerable due to their longevity and low reproductive rates. The red kite (Milvus milvus) is one of few migratory raptors breeding exclusively in Europe. It has previously experienced steep population declines caused mainly by persecution but mostly recovered, no longer classified as globally endangered. However, negative population trends persis

Karakterisering av ert-c mutanter i sädesslaget korn För att säkra vår mattillgång behöver vi bättre grödor. I modern tid har det blivit vanligare med kraftiga regn kombinerat med starka vindar. Detta ökar risken att grödor trycks ner på market, vilket minskar skörden och påverkar skördens kvalitet. Kortare växter som ert-c mutanter är mer tåliga mot sådant väder och i mitt arbete hoppades jag kuThe barley erectoides (ert) mutants are characterized by an erect growth habit, a short and compact spike and often a short culm length. The ert-c mutant group consists of 40 allelic mutants and is thus one of the largest groups. The aim of this study was to identify the ert-c gene. The genomes of eight ert-c mutants have been sequenced and a set of candidate genes were identified. In the present
