We present a topology optimization framework for anisotropic elastoplastic structures based on a new deformation plasticity formulation derived directly from Hill’s yield criterion. Conventional incremental elastoplastic approaches in topology optimization, while accurate, are computationally demanding due to their path-dependent nature and the need to store internal variables over multiple load s

This thesis investigates quantum dynamics induced in atoms by ultrashort pulses of light. The work is motivated by recent developments in free-electron lasers, which generate ultrashort pulses of intense, coherent light and enable coherent control of quantum dynamics. We develop theoretical models to study the processes of absorption and emission in laser-atom interactions. Additionally, we study

This paper presents a predicted information and predicted action (PIPA) decision-analysis approach with Bayesian material updating for planning material testing in existing reinforced concrete members. The objective is to select the number of concrete and reinforcing-steel tests before testing is performed and before a management action is chosen, accounting jointly for the updated structural perf

This article aims first to understand how and why refugees decide to leave or stay in their first country of asylum, and second to contribute to the theory of agentic analyses of migration. Our contribution adds to the growing body of research examining the impact of social class and associated capitals on the trajectories of forced migrants. Our analysis of the experiences of Syrians in Turkey an

Disruptions of the patient-general practitioner (GP) relationship due to GP exits affect patient outcomes in various ways. The literature suggests that the loss of a trusted professional can have negative effects, but also points at the benefits of being examined by a new GP. We study the impact of GP exits in the Swedish primary care setting, in which care is provided in group practices and even

This licentiate thesis is based on two papers related to convergence analysis of numerical schemes that contain stochasticity for problems under low-regularity assumptions. The first paper is about a randomized Runge-Kutta scheme for stiff ODEs. The second paper is on a domain decomposition method for parabolic SPDEs.In the first paper, we show that a two-stage singly diagonally implicit Runge-Kut

Atmospheric neutrinos provide a unique avenue to study neutrino interactions in matter. In this work, the prospects of constraining non-standard neutrino interactions with atmospheric neutrino oscillations are investigated for the proposed ESSnuSB far detector. By analyzing atmospheric neutrino samples equivalent to 5.4 Mt·year exposure, it is found that ESSnuSB could be able to set the upper boun

Det är en vanlig uppfattning att demokratin i 1800-talets Europa steg som en våg eller ett tidvatten i takt med ekonomisk tillväxt, liberala reformer och modernisering i största allmänhet. Uppfattningen sammanfattas av David Art, professor i statsvetenskap vid Tufts University i Boston, i inledningen till The Resilience of the Old Regime enligt följande (s. 3): ”Det gemensamma elementet i dessa be

High-resolution synchrotron X-ray tomography combined with digital volume correlation (DVC) enables characterization of three-dimensional strain fields. When local tomography is used to investigate specimens larger than the field of view (FOV), the resulting subvolumes must be stitched together to form a single volume, thereby introducing strain uncertainties in DVC analyses. The present work quan

Innovation and technological progress have been identified as key drivers of long-term economic growth. However, not all innovation is supporting sustained economic growth or addressing societal concerns such as climate change. Against this backdrop, researchers advocate for active government intervention in shaping technological development, a role that governments have increasingly assumed in reInnovation and technological progress have been identified as key drivers of long-term economic growth.

The XT03 beamline at the HIE-ISOLDE facility provides a flexible platform for a broad range of non-permanent reaction experiments with accelerated radioactive ion beams. At its focal plane, the Scattering Experiment Chamber (SEC) offers a large, modular volume capable of hosting diverse internal detector setups.

In dense urban housing, particularly at high latitudes, the provision of direct sunlight creates a critical trade-off between its value as a residential amenity and the need to ensure occupant comfort and energy-efficient performance. This study investigates indoor sunlight preferences through a national survey in Sweden, providing updated empirical evidence for residential building design. The fi
