Fingerprint recognition has become a popular authentication method in modern smartphones, replacing traditional passwords and PINs. However, smartphone fingerprint sensors are small and capture only partial fingerprints with limited resolution. Combined with varying image quality and inconsistent finger placement, multiple images must be stored per user to ensure reliable authentication. During ve
This study explores how knowledge, communication, and influence are organized within the consultation reports of the Swedish urban planning practice. The study is based on collaborative planning theory and analyses the extent to which the consultative process is grounded in collaborative or performance- or criteria-driven planning logic. Through a qualitative content analysis of consultation repor
This thesis explores how immersive virtual reality can be designed to support emotional engagement, relaxation, and a sense of connection to nature. Based on experience design and gesture interaction theory, this project developed a VR experience titled "Night Journey". In this experience, users can explore a virtual nature and interact with a responsive ecosystem through natural body ge
This study investigates how varying hyperparameters of the Synthetic Minority Over-sampling Technique (SMOTE) affects the stability of model explanations produced by SHapley Additive exPlanations (SHAP) and Local Interpretable Modelagnostic Explanations (LIME). By using an eXtreme Gradient Boosting (XGBoost) classifier trained on 11 medical datasets with varying imbalance ratios, four SMOTE parame
Introduction: Liquid-liquid phase separation (LLPS) is a process that occurs often in biological environments, and elastin is a protein that utilizes it to form elastic fibres. Understanding elastin’s LLPS is very helpful for creating new biomaterials and researching diseases, where LLPS occurs. Background: The coacervation of elastin is widely researched, but the combination effects of salt, hea
In 2025, the unauthorized release of four lynx in Scotland sparked widespread media speculation about “guerrilla” rewilding. Drawing on political ecology and environmental justice, this thesis applies a critical discourse analysis to investigate how media outlets framed lynx reintroduction following the unauthorized release. The findings show that media coverage constructs rewilding as contentious
This study examines how tourism affects and reshapes residents’ identities and sense of place in the Sanno-chiku of Takayama City in Gifu Prefecture, Japan. This study focuses on residents’ lived experiences and discusses tourism through the ideas and concepts of place, sense of place, identity, mobility, and commodification. This study asks two research questions: 1) How does tourism shape local
Polyhydroxyalkanoate (PHA) synthases (PhaC) are the pivotal biocatalysts governing the biosynthesis of biodegradable polyesters. Current research on their structure and mechanisms remains limited, and the chemical mechanisms of all PHA synthases are still under debate. Despite some speculation, further physicochemical studies are needed to understand their structure and function. The primary obje
This master’s thesis explores the ethnic self-identification of young Russian speakers from Estonia, as well as their sense of belonging to Estonia and the Estonian society. The research focuses on an understudied group of younger people who did not experience the life under the Soviet Union, which leads to them not sharing the identification of a “Soviet citizen” that was common for the older gen
Ring voltage-controlled oscillators (Ring VCOs) are widely used in clock generation because of their compact area and wide tuning range, but their high inherent phase noise limits their application in high-performance systems. To address this, this thesis presents a low-power dual-path sub-sampling PLL (SSPLL) covering a wide frequency range from 2GHz to 4GHz. To effectively suppress the phase noi
Disasters are social and political constructs, and their impacts are shaped by people’s action and inaction. How we allocate time, money, and resources matters in shaping the outcomes post-disaster, especially of those most vulnerable. While the lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community is an understudied demographic in disaster research, existing studies show that LGBTQ+ p
Att leva med klusterhuvudvärk innebär att hantera återkommande smärtanfall och samtidigt leva med osäkerheten kring när nästa anfall kan inträffa. Denna uppsats analyserar klusterhuvudvärk som ett temporalt livsvillkor snarare än enbart som ett neurologiskt smärttillstånd. Med utgångspunkt i tio kvalitativa intervjuer med personer som har diagnostiserad klusterhuvudvärk undersöks hur återkommande
Inflight safety briefing videos are shown on flights to communicate crucial safety information. However, passengers often ignore these videos as they are perceived as repetitive and unengaging. This study explores whether passenger engagement can be increased through the use of gamification. An iterative user-centered approach was adopted to evaluate both traditional safety briefing videos and a g
With four years left to fulfill the goals of the UN’s Ocean Decade, it has become increasingly important to find solutions for the threats our oceans are currently facing. French Polynesia has the largest marine protected area in the world and relies heavily on tourism for development. Through semi-structured interviews with stakeholders in the tourism industry in Tahiti, I study their role in mar
Materialvariation i gråjärn diskuteras vanligtvis utifrån metallurgi eller bearbetbarhet, medan dess konsekvenser för produktionsflödet och styckkostnaden är mindre systematiskt karaktäriserade. Detta examensarbete undersöker hur sammansättningsvariation i gråjärn propagerar genom bearbetningsrespons till produktionssystemets beteende, och kvantifierar de resulterande ekonomiska konsekvenserna perMaterial variability in grey cast iron is usually discussed in terms of metallurgy or machinability, while its consequences for production-flow behaviour and per-part economics are less systematically characterised. This thesis investigates how compositional variability in grey cast iron propagates through machining response into production-system behaviour, and quantifies the resulting per-part e
Marine protected areas (MPAs) are promising tools to protect and restore marine ecosystems among a global biodiversity loss crisis, yet their socio-ecological effectiveness can be limited by a lack of stakeholder participation in their governance. This thesis examines the case of participatory governance in Germany’s three exclusive economic zone (EEZ) MPAs in the North Sea. Drawing on participato
This thesis examines the compatibility of the Principle of Economic Reality against the Principle of Legality in Danish law and the Principle Legal Certainty in EU law within the context of Danish transfer pricing regulation. Utilizing the legal dogmatic method, the thesis establishes the principles and the Danish transfer pricing framework. It then employs the Dubai A case as a central case
Positiv psykologi har breddat psykologins fokus bortom enbart symtomreduktion, men det finns begränsad kunskap om hur psykologer själva upplever att arbeta med detta i praktiken. Denna kvalitativa studie undersökte legitimerade psykologers erfarenheter av att tillämpa positiv psykologi i professionella sammanhang. Semistrukturerade intervjuer genomfördes med fyra legitimerade psykologer verksamma Positive psychology has broadened psychology’s focus beyond symptom reduction, yet little is known about how psychologists themselves experience working with it in practice. This qualitative study explored licensed psychologists’ experiences of applying positive psychology in different professional contexts. Semi-structured interviews were conducted with four licensed psychologists working in scho
The EU Deforestation Regulation marks a major shift in European forest and commoditygovernance by moving from legality-based timber control toward mandatory deforestationfree due diligence. While the regulation is designed to address global deforestation linkedto consumption and trade, its implementation also affects low-deforestation contexts suchas Sweden. This thesis examines how Swedish forest
Klimatförbättrad betong erbjuder en av byggsektorns mest tillgängliga vägar till minskade utsläpp. Utnyttjandet begränsas dock i praktiken mer av produktionsförhållanden och tradition än av materialet i sig. Betongproduktion står för en betydande del av de globala koldioxidutsläppen. Cement, en av de huvudsakliga komponenterna i betong, går delvis att ersätta med tillsatsmaterial som mald granuleCement production accounts for a significant share of global carbon dioxide emissions, which has made the development of climate-improved concrete a central concern for the construction industry. Replacing part of the cement with supplementary cementitious materials reduces the climate impact, but slows the development of early-age strength, an effect particularly pronounced at low temperatures.
