Mapping spatial variability of bioavailable strontium isotopes (87Sr/86Sr) is fundamental to robust analyses of prehistoric human and animal mobility and provenance based on strontium isotope data. A key challenge is how to construct and extrapolate a baseline for specific landscapes to enable meaningful correlation with high-resolution archaeological data. This study presents a regional high-reso

For victims of corporate harm, accessing justice in the global landscape is fraught with challenges and limitations – but also contestation and conflict. This paper focuses on these issues by directing attention to the National Contact Points (NCPs), a nonjudicial grievance mechanism in this landscape. It explores the puzzle of why complainants, who portray the NCP as a mechanism that is unlikely

Effective environmental policies for the tropics depend on accurate, representative scientific data. However, there is strong evidence from particular disciplines and regions that existing research is patchily distributed. Here, we show that poor representation of sampling and citation in some biomes and across key environmental gradients from all disciplines for the entire tropics may lead to fla

Background: The aim was to evaluate whether an artificial intelligence (AI)-based tool for the automated quantification of the total metabolic tumour volume (tMTV) in patients with Hodgkin lymphoma (HL) could support nuclear medicine specialists in lesion segmentation and thereby enhance inter-observer agreement. Methods: Forty-eight consecutive patients who underwent staging with [18F]FDG PET/CT

The Atlantic world looms large in discussions of how the modern world emerged, and what modernization was about; but there have been calls to engage with these topics from the perspective of ‘margins’. Covering large areas of Fennoscandia, the seventeenth-century Kingdom of Sweden represented a northern end of urban Europe, but also encompassed the mythical Lapland, homeland of the Sámi and of nat

In 1634, silver was found in inland Sápmi, on the present border between Norway and Sweden. The Swedish Crown had the ore extracted and a works for refining the silver was established in Silbojokk the following year. During the coming decades, two more works and many mines were opened in Sápmi. Sámi, Swedish and Dutch/German migrant workers were employed under restrictive conditions and in a harsh

A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide mass range (108 < M bar/M⊙ < 1011 M⊙); this is known as the radial acceleration relation (RAR). This has been interpreted as evidence that dark matter is actually a manifestation of a modified, weak-field gravity theory. In this work, we studied the radially resolved RAR of 12 nearby dwarf

Swedish architectural modernism is intimately tied to thedevelopment of the welfare state, where the roles and work ofarchitects largely followed governmental building policies. Thepolitical and economical crisis of the late 1960s and 1970swas particularly devastating for Swedish architecture as theshortcomings of the welfare state were partly blamed on thearchitecture profession. This paper is a

This article seeks to develop an understanding of how corporations manage their social and ethical responsibilities, whilst simultaneously facing allegations of crime. It draws on the case of TeliaSonera, a Swedish corporation prosecuted for committing bribery in Uzbekistan. The article begins by introducing the reader to this so-called ‘Uzbek affair’, before exploring how corporate governance has

This thesis presents an incremental Structure-from-Motion pipeline through the use of affine transformations of monocular depth priors. The scene points are triangulated by averaging lifted covisible keypoints utilizing the calculated transformations. Each new image is registered to the reconstruction by first estimating the camera pose, then aligning the depth prior to the observed 3D points. We

The automation of floor plan interpretation and reconstruction is a key challenge in architectural visualization workflows, particularly when handling heterogeneous, real world data. This thesis project investigates the use of deep learning–based semantic segmentation combined with geometry-aware postprocessing to automate the extraction of structural elements from floor plan images. The work is m

This study investigates the interaction problem between a differentialdrive mobile manipulator and one-degree-of-freedom (1-DoF) mechanisms. While previous research has focused on stationary robotic platforms, this work puts emphasis on mobile interaction. Building upon a previously proposed adaptive control strategy for fixed-base manipulators, a holistic control framework is developed to coordin

On-Orbit Servicing (OOS) missions are central to reducing space debris, and their success depends on accurate pose estimation of non-cooperative satellites. Existing state-of-the-art tracking frameworks, such as the Multi-Modal Model-based Tracker (M3T), rely on color histograms and therefore degrade significantly when constrained to grayscale input, which is the standard in space. This thesis inv

This architectural thesis investigates a general system for a sustainable tourism-related built environment in the Swedish mountains. With a growing interest in hiking and nature-based tourism, the Swedish mountain landscape has become an increasingly popular destination, while at the same time serving as important grazing land for reindeer. This calls for careful development and reduced environme

Improving the efficiency of combustion engines is crucial from an environmental perspective, serving as a complement to the transition towards the electrification of transportation. To optimize combustion efficiency, the amount of air in the cylinders needs to be estimated, which today is done by gray box-models based on traditional physics. This thesis examines the possibility of complementing th

This thesis investigates human–robot co-manipulation in which a mobile manipulator assists a person in handling and maneuvering a jointly held object. A cooperative control strategy is developed that enables the robot to guide its motion by the human forces transmitted through a jointly held object. In this framework, the mobile base provides the primary movement while the manipulator maintains ob

Reliable six-degree-of-freedom pose estimation is a key requirement for autonomous on-orbit servicing (OOS), in which a robotic spacecraft performs tasks such as inspection, maintenance, and life extension of other satellites in orbit. However, generating trustworthy ground truth for algorithm development remains challenging. This thesis investigates calibration, sensor evaluation, and sensor fusi
