Water management is a critical factor for the performance and reliability of polymer electrolyte fuel cells (PEFCs) operating as energy generation systems. Inadequate operating conditions may lead to non-uniform water distribution, resulting in membrane dehydration or flooding of porous media, both of which adversely affect cell operation. In this work, a two-dimensional reduced-order model is dev
Musculoskeletal health is essential to health, well-being, and independence across the life course. Musculoskeletal conditions including inflammatory joint diseases, osteoarthritis, back pain, osteoporosis, and fragility fractures are among the greatest causes of disability globally imposing a major burden on health and social care and economic impact also through lost productivity. Despite effect
BACKGROUND: The aim was to improve the realism of patient models for Monte-Carlo based evaluation of image-based quantification of tumour volume and activity in [68Ga]Ga-DOTA-TOC PET and [177Lu]Lu-DOTA-TATE SPECT images.METHODS: Three phantoms from the XCAT population were used as basis. Tumour structures were obtained from segmentation of patient 68Ga-PET images and positioned at relevant positio
Lignins are a polymeric, renewable resource with remarkable structural diversity. Research is being conducted into the valorisation of lignins into value-added products. The absence of experimental libraries, in particular for process-modified oligomers, hampers analytical feedback to these valorisation efforts. Stochastic methods for generating libraries in-silico have been proposed, but were not
Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl
The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order
The global industrial sector is a highly polluting and greenhouse gas-emitting sector. As industries increasingly explore Artificial Intelligence (AI) to enhance operational efficiency and drive innovation, questions emerge regarding its alignment with sustainability objectives. While AI is often positioned as a key enabler of digital transformation, its sustainable integration into industrial ope
Hydrogen plays a pivotal role in the global energy transition, offering a clean and versatile energy carrier for a sustainable future. However, ensuring its safe use in industrial facilities requires reli- able prediction of dispersion from Venting Units (VUs). Traditional computational fluid dynamics (CFD) simulations provide high-fidelity results but are too slow for fast safety assessment and i
As industrial sectors and digital infrastructure expand, the global demand for high-volume, reliable manufacturing of thermal management solutions like heat exchangers continues to accelerate. This thesis investigates the design and optimization of an automated robotic assembly cell for heat exchanger production at Alfa Laval using Discrete Event Simulation (DES). The primary objective was to defi
α-CGRP 8-37 is a peptide fragment of calcitonin gene-related peptide and is commonly used as a CGRP antagonist in pharmacological research. CGRP signaling has been discussed in relation to neuroimmune mechanisms in psoriasis, but a practical development of α-CGRP 8-37 requires analytical methods and formulation strategies that can handle peptide instability, adsorption, and matrix effects. The aim
This thesis investigates the design and evaluation of Large Language Model (LLM) agent assistants for industrial maintenance, developed in cooperation with SSAB. The study focuses on identifying what combinations of tools and architectures best serve the needs of maintenance technicians, with an emphasis on practical usability and factual correctness. Multiple agents were developed and compared,
Cybersecurity has never been more relevant than it is today, as attacks become increasingly sophisticated. To keep devices safe from threats, a new type of smart firewall has become an active area of research. This type of firewall can dynami- cally configure itself based on incoming network traffic using reinforcement learn- ing. This research has shown promising results; however, its impact on r
Non-terrestrial networks (NTNs) are expected to become an important component of future sixth-generation (6G) wireless systems by extending broadband coverage to remote, maritime, aerial, and underserved areas. Among different NTN platforms, low Earth orbit (LEO) satellite constellations are particularly attractive due to their lower propagation delay compared with geostationary systems. However,
Traditional football analytics largely evaluates players through on-ball events such as shots, passes and dribbles, leaving the much longer periods of off-ball play poorly measured. This thesis develops a spatial framework for evaluating individual player contributions in crossing situations, where a cross is defined as an aerial or driven delivery from a wide area into the central penalty zone. T
Direct-to-Device (D2D) communication in Non-Terrestrial Networks (NTNs) enables smartphones to connect directly to satellites, extending wireless coverage beyond terrestrial networks. This thesis presents the design of a smartphone antenna optimized for NTN operation, followed by a link budget analysis and Electromagnetic Field (EMF) exposure assessment. The proposed solution is a dual-band circu
This paper aims to contribute to the already ongoing scientific discussion about socioeconomic factors and interpersonal trust. More specifically how parents educational level and view of one's self income influences this relationship. This study takes on a Swedish perspective and measures to what extent different variables affect the relationship. The analysis in this paper uses a multiple re
The demand for cost- and time-effective and customizable components for High Vacuum (HV) and Ultra-High Vacuum (UHV) systems has prompted exploration into the application of 3D-printing technology. This study investigates the viability of utilizing 3D-printed plastics in UHV environments by evaluating their outgassing properties. An extensive evaluation of 3D-printing materials was carried out, hi
