Technical drawings play an important role in many industrial processes, including product development, manufacturing, and lifecycle management, by representing the product definition. The purpose of the study was to investigate which processes influence technical drawing creation and management, what challenges are associated with these processes, and how these challenges can be addressed through
This thesis presents the design and schematic-level simulation of a highly linear mixer-first receiver front-end implemented in CMOS, targeting improved robustness against strong input signals. The proposed architecture employs a current-mode passive mixer directly loaded by a low-impedance transimpedance amplifier (TIA) in order to minimize the voltage swing at the mixer output and thereby enhanc
Background and objective Bullying among adolescents is a growing public health concern with serious mental, emotional, and social well-being consequences. This study aims to assess prevalence of physical and cyberbullying among school-going adolescents (13–17 years) in Himachal Pradesh, India, and identify risky and protective factors using an ecological framework descriptively. Methods A cross-se
With approximately 94 percent of traffic accidents being caused by human error, improving driver behaviour has the potential to save lives. To encourage safer driving, Volvo Cars is developing a Safety Coach feature for their mobile application. However, pilot studies of a minimum viable product (MVP) indicated low user retention, suggesting the need for design elements that better support user en
AI-Assisted and Semi-Autonomous tools are becoming relevant for enterprises. The adoption of these tools requires understanding how different practitioners perceive and use them responsibly in their organizations. This thesis examines how enterprise software development practitioners govern AI-assisted and semi-autonomous tools in everyday development workflows. As these tools increasingly support
Sex differences in cutaneous melanoma (CM) survival are pronounced. It is unclear how these differences impact the loss in life expectancy (LLE). A population-based cohort from the Swedish Melanoma registry was used to analyze sex differences in life expectancy (LE) and LLE following a CM diagnosis. The cohort included 12,893 men and 12,572 women aged 40 years or above diagnosed with a first invas
Methane (CH₄) emissions from landfills are a key uncertainty in Sweden’s national greenhouse gas inventory. This thesis evaluates whether UAV-based CH₄ measurements can complement inventory-based estimates, using Filborna landfill in southern Sweden as a case study. UAV-derived emissions from 2022–2024 were compared with an IPCC Tier 2 First Order Decay model, reproduced from Sweden’s national inv
This study examines the underlying qualities of young adult students' judgments on Swedish drug policy by conducting and analysing six interviews with students at Lund University. Deploying thematic analysis, this study explores the moral boundaries and social values underpinning the explicit opinions of the interviewees. The analysis is further informed by theories on moral regulation, the po
Att identifiera proteinmönster associerade med lungsyndromet acute respiratory distress syndrome (ARDS) hos patienter med underliggande sepsis är en central utmaning inom intensivvårdsforskning. Konventionella univariata metoder riskerar att missa icke-linjära associationer och högre ordningens interaktioner som speglar syndromets sanna komplexitet, och systematisk utvärdering av alternativa metodIdentifying proteomic patterns associated with acute respiratory distress syndrome (ARDS) in sepsis patients is a central challenge in critical care research. Standard univariate approaches may miss non-linear associations and higher-order interactions that reflect the true complexity of the syndrome, yet systematic evaluation of alternative methods is lacking. This thesis introduces a unified eva
Limited-slip differentials (LSDs) are commonly used in high performance vehicles to im- prove handling by reducing differential speed and balancing torque between the driving wheels. BorgWarner develops electronically activated LSDs and Electric Cross Differen- tials (eXD), which dynamically control torque distribution to improve traction and vehicle performance. However, current electrically acti
This study developed and evaluated a process-based hourly winter wheat model for harvest area 1214 in Skåne, southern Sweden, during 2004-2022. The model was calibrated using 2021/22 field observations from Alnarp and then applied in an ensemble hindcast with hourly meteorological forcing and regional yield statistics. Calibration improved the simulation of crop development, reducing LAI RMSE by 7
Political polarisation is reshaping the institutional environment in which social ventures operate, yet research on social venture legitimacy still largely assumes stable, consensus-driven settings. This study explores how social ventures in Sweden reframe to maintain or reconstruct legitimacy when that consensus breaks down. Ten semi-structured interviews were conducted with founders and senior l
This thesis investigates the potential of using protective relay data for power outage prediction in medium-voltage distribution networks operated by E.ON Sverige AB. The study is based on retrospective relay recordings from seven substations in the Swedish distribution grid, covering the period 2018-2026. The analysis focuses on whether abnormal relay activity before outages contains systematic p
This paper studies the relationship between Thai-Cambodia border tensions and cooperation against online fraud from February 2021 to February 2026. Online fraud has become a serious cross-border problem in Southeast Asia, and Thailand and Cambodia both have reasons to cooperate against scam compounds and related criminal networks. At the same time, their relationship is shaped by a long history of
Through in-depth qualitative interviews with 17 men and one woman, this thesis investigates masculinity and ‘honor’ in the daily lives of Iranian-Swedish men living in Skåne. The aim of this thesis is to study the men’s description of ‘honor’ and the situations in which it appears as masculine practices in everyday life. For this purpose, a theoretical framework including theories of masculinities
Atmospheric particles play a significant role in radiative forcing through light scattering and new methods are called for to better characterize their impact. Typical Lidar systems emit single wavelength light, not utilizing full spectral information from scattering measurements. This thesis aims to use a hyperspectral lidar system to measure the spectral dependence of scattering and absorption
Air pockets in pressurized pipelines may reduce hydraulic capacity, increase head losses, and affect system operation. In downward sloping pipe sections, a key question is whether the water flow can transport a trapped air pocket downstream or whether the air is likely to remain stationary, which would require an air valve to evacuate the air. This thesis compares selected criteria and guidance so
Våtmarker bidrar med många ekosystemtjänster såsom kolinlagring och förbättrad vattenkvalitet och tillgänglighet. Historisk dränering har dock lett till en massiv förlust av våtmarker världen över, vilket resulterat i förlorade ekosystemfunktioner och ökade utsläpp av växthusgaser. Idag finns ett ökat intresse för återställning av våtmarker för att nå beslutade klimat- och miljömål. Det finns dockPeatlands provide several ecosystem services such as carbon sequestration and improved water quality and availability. However, historical drainage has led to a massive loss of peatlands worldwide, resulting in lost ecosystem functions and increased greenhouse gas emissions. Today, environmental goals have led to a renewed interest in the restoration of peatlands. However, knowledge gaps regarding
