The All Pairs Shortest Path (APSP) problem is ubiquitous in computer science. The problem consists of finding for any vertex pair, the weighted shortest paths in a network with real-weighted edges. The problem has been studied thoroughly, both for dense graphs, where the number of edges can be quadratic in the number of vertices, and for sparse graphs, where the number of edges is considerably low
This Master’s thesis studies the effect of infrasound acoustic waves on heat transfer enhancement for industrial purposes. Previous research has demonstrated the cap ability of infrasound to cool steel uniformly, with performance comparable to forced convection. This opens the possibility of increasing the efficiency of the cooling process while also enabling new potential cooling methods for diff
Detta examensarbete har fokuserat på att modernisera styrsystemet för reservpanna 3 vid Hetvattencentralen i Landskrona, genom att ersätta ett äldre SCADA-baserat system Uniview med ett modernt distribuerat styrsystem (DCS) ABB 800xA. Arbetet har genomförts i samarbete med Deterministic Control AB, och med Landskrona Energi AB som slutkund. Syftet med examensarbetet har varit att uppnå en fullstänThis thesis focuses on the modernization of the control system for Backup Boiler 3 at District heating plant in Landskrona. The objective was to replace an outdated SCADA-based system, Uniview, with the modern Distributed Control System (DCS) ABB 800xA. The project was carried out in collaboration with Deterministic Control AB, and with Landskrona Energi AB as the final customer. The main goal was
This bachelor thesis explores nonbinary people’s experiences of joy and community, as well as how we are affected by social exclusion, anti-gender ideology, unintelligibility, and questions about whether nonbinary people actually exist. The aim of the thesis is to contribute to crucial efforts to amplify the voices and experiences of nonbinary people. Through interviews with five nonbinary people
As lithium-ion batteries become central to the European Union’s (EU) clean energy transition, particularly in electric vehicles and energy storage systems, concerns have grown regarding the sustainability of their full lifecycle. Recycling is increasingly recognized as a key strategy to mitigate environmental impacts, reduce reliance on primary raw materials, and support the EU’s circular economy
The purpose of this study is to examine how the Swedish court of law determined intent in cases of sexual and traffic offences where the defendant claimed to have acted whilst being in a state of somnambulism. The starting point of intent assessment is permeated with uncertainty about the defendant’s level of consciousness. Since there is a significant lack of guiding practice in cases of this nat
Utformningen av utrymmen för pianoframträdanden kan bidra till att forma pianistens psykologiska upplevelse, vilket i sin tur påverkar deras prestationsresultat. Denna avhandling utforskar hur rumsliga konfigurationer – såsom publikens närhet, scenens utformning, rummets storlek och belysning – kan påverka pianistens mentala tillstånd, inklusive stress, fokus och självförtroende vid scenframträdanThe arrangement of piano performance spaces can contribute to shaping the psychological experience of pianists, which in turn influences their performance outcomes. This thesis explores how spatial configurations—such as audience proximity, stage layout, performance room size, and lighting— could affect pianists' mental states, including stress, focus, and confidence when performing on stage.
The aim of this thesis is to explore jets traversing the Quark-Gluon Plasma (QGP)created in Pb-Pb collisions. This is done in the simulation program XSCAPE with a center of mass energy of 2.76 TeV. By categorising the jets by their azimuthal angle with respect to the event plane angle, the path length dependence of the energy loss was studied. The path length classification was described with the
This essay explores the lived experiences of parents of children with neurodevelopmental disabilities in relation to institutional interactions. Using a narrative inquiry approach (Clandinin & Connelly, 2000), 13 semi-structured interviews were conducted and analysed to investigate emotional and moral dimensions of the participants' stories. Drawing on Kittays (1999) ethic of care, the
Artificial intelligence (AI) is rapidly transforming healthcare, yet its successful integration depends heavily on the acceptance and understanding of this technology by medical professionals. Our qualitative exploratory study, using semi-structured interviews with eight medical professionals in Sweden and Denmark, charts their perceptions of AI's implementation in medicine. The primary goal o
This paper examines how Artificial Intelligence (AI) and the AI-act affect the rights of the employee within the Swedish labour market, focusing on integrity. By analyzing different perspectives of the labour market´s AI-use the aim is to understand how employee rights are accommodated. The adjustment due to the AI-act attribute to the understanding of changing labour market conditions related to
The chaperone protein DNAJB6b exhibits intrinsic activity in inhibiting amyloid fibril formation, although the underlying mechanism remains unclear. A key region, comprising residues 132-183 and rich in serine and threonine residues, commonly referred to as the “S/T region”, has been shown to play a critical role in this function. While deletion of the S/T region does not disrupt the folding of DN
This study investigates the relationship between cornerstone allocation and IPO underpricing in the Swedish market, as well as the moderating role of valuation uncertainty on this relationship. Employing OLS and 2SLS frameworks on a sample of 429 Swedish IPOs from 2010 to 2024, we find evidence of a causal non-linear relationship between cornerstone allocation and IPO underpricing, taking the form
Deterministic Galerkin finite element methods deliver high-fidelity solutions of partial differential equations (PDEs) but do not fully capture the inevitable uncertainty in material parameters, boundary conditions and external forcing. This thesis presents a unified framework that spans classical Galerkin discretisation and its stochastic counterpart, enabling uncertainty simulation of diffusion-
The study aims to focus on the employees' experiences as well as practices of the leaders' leadership styles in rapidly changing environments to contribute to a deeper understanding of leadership combinations. Although research has been conducted regarding different leadership approaches, there is limited research that explores the understanding of how entrepreneurial leaders combine and a
Danielsson, F. 2025. The senses, the churches and the forest: Sensory archaeology in Örkelljunga and Perstorps church. Medieval churches have been a foundational area of inquiry for the field of historical archaeology since its conception at Lund university in the 1960’s. Since then, plenty of studies have been conducted that examines medieval churches from a top-down approach while other aspects

This thesis examines representations of homosexual men in Swedish media and public information campaigns during the hiv/aids epidemic, using materials published 1983-1996. The thesis centers on how concepts such as homonormativity and homonationalism are reflected in the discourse, along with an exploration of the rhetorical strategies employed by journalists to increase readership. A thematic ana
Losses and damages induced by climate change are increasingly felt by communities worldwide, disproportionately affecting communities relying on subsistence agriculture. Peru is one of the countries most vulnerable to losses and damages, due to its high exposure to climatic risks and the relative vulnerability of its population. To respond to climate-driven loss, the Warsaw International Mecha
