Changing illumination constitutes a serious challenge for video segmentation algorithms, especially in outdoor scenes under cloudy conditions. Rapid illumination changes, e.g. caused by varying cloud cover, often cause existing segmentation algorithms to erroneously classify large parts of the image as foreground. Here a method that extends existing segmentation algorithms by detecting illuminatio
Although the reduction of iron oxides has been widely studied using bulk characterization techniques, direct observations of surface chemical states under reaction conditions remain limited. Here, the reduction behavior of iron oxides in a CO/H2 atmosphere is investigated using ambient-pressure X-ray photoelectron spectroscopy (APXPS) combined with ex situ microstructural characterization. APXPS r
Clear and effective central bank communication is essential for shaping market expectations and supporting the transmission of monetary policy. This paper examines whether differences in the messages conveyed by individual policymakers affect how financial markets respond to monetary policy decisions. Using a novel measure of communication dispersion constructed from European Central Bank board me
BackgroundUnderstanding how physical fitness develops during adolescence is critical for interpreting and optimizing training and setting realistic performance expectations in youth sport. Yet, evidence-based, age-referenced benchmarks that track multiple fitness components across sports remain lacking, leaving practitioners without reliable normative trajectories to guide athlete development.Purp
Continuously indexed Gaussian fields (GFs) is the most important ingredient in spatial statistical modelling and geo-statistics. The specification through the covariance function gives an intuitive interpretation of its properties. On the computational side, GFs are hampered with the "big-n" problem, since the cost of factorising dense matrices is cubic in the dimension. Although the computational
Purpose: To investigate adenoma progression, pituitary function, visual impairment, and need for later surgery in elderly patients with conservatively managed nonfunctioning pituitary macroadenomas (macro-NFPAs). Methods: Patients ≥ 65 years in the Swedish Pituitary Registry diagnosed 1991–2023 with macro-NFPA and a decision for conservative management were included (n = 673, 38% females). Data at
This study investigated the mechanistic effects of β-glucan and cellulose on the microstructure, rheological properties, and digestion behaviour of oil-in-water emulsions stabilised by whey protein (WPC) or rapeseed protein (RP). The WPC emulsions exhibited a monodisperse droplet distribution (D90 = 2.8 μm), whereas RP emulsions displayed a bimodal distribution with substantially larger droplets (
This thesis, informed by democratic backsliding theory, neocolonialism, reproductive governance and backlash theory, examines how the Mexico City Policy has become a political instrument through which reproductive rights are regulated within U.S. foreign assistance. The thesis argues that the repeated reinstatements and successive expansions of the policy since its introduction in 1984 do not mere
Much research on smallholder farming and climate uncertainty has focused on Global South contexts, but relatively few studies examine smallholder farmers in industrialised agricultural settings. This thesis examines how smallholder farmers in the Lund area of southern Sweden experience and respond to climate uncertainty through everyday farming practices and intergenerational knowledge. The study
Civil society actors play a vital role in supporting sexual and gender minority migrants and asylum seekers, yet the impact of the reliance on external funding on these organizations remains largely unexplored. This thesis aims to understand the impact of external project-based EU funding on the Swedish CSO RFSL Newcomers. Through expert interviews and document analysis, a critical realist case st
Open-field tomato (Solanum lycopersicum L.) production in the western Mediterranean is increasingly exposed to temperatures exceeding reproductive thresholds. Existing projections focus on the largest processing regions, the United States, Italy, and China, and omit the two producers that anchor Mediterranean supply on either side of the Strait of Gibraltar. Neither Spain, the region's second-
Modern wireless communication systems are increasingly operating in high-frequency bands to support applications requiring low latency, high bandwidth, and high data rates. Achieving reliable performance in these bands requires accurate channel characterization, particularly in complex indoor settings such as industrial environments, where numerous objects influence radio signal propagation throug
During 2019–2021 the ruins of the medieval church in Edsleskog, Dalsland were excavated. Upon unearthing the church, it was concluded that it was most likely the oldest known brick building in Sweden. The church was also huge and shared many architectural similarities with contemporary cathedrals. The small hamlet of Edsleskog is located in the northern forests of Dalsland, a region that histo
Southern Scandinavian and Scanian settlement archaeology has in the past four decades been able to highlight overarching shifts in prehistoric and especially Iron Age settlement organisation, and thus developed methods of rigorous typo-chronological analyses. Within the past two decades several publications by Late Iron Age scholars have under the influence of household archaeology emphasised the
The concept of 'genocide' is rarely employed by prehistoric archaeologists within their research. The hesitation of scholars to use the term is argued to be due to its overall complexity and its supposed existence as a recent phenomenon of modernity, as well as its rash use in popular science outlets when reporting on prehistoric migration. Examining and comparing prehistoric massacres wit
Colonialism has been a significant influence on the shape of our modern world. Colonialism creates power structures and social systems that continue to inform contemporary institutions and systems of knowledge production. Archaeology has historically been connected to these colonial structures by privileging hegemonic and Eurocentric epistemological research structures. In efforts to acknowledg
This thesis investigates the collected surface assemblage from Shubayqa 3, an unexcavated prehistoric site in the Qa’ Shubayqa region of north-eastern Jordan. It examines what surface-collected lithic material can reveal about chronology, spatial organisation, and repeated activity, while also considering the limitations of a mixed assemblage without secure stratigraphic context. The study combine
