Denna studie undersöker nedsiderisken i nordiska hedgefonder under covid-19-krisen 2020 och inflationschocken 2022, i jämförelse med indexfonder, blandfonder och aktivt förvaltade aktiefonder. Value at Risk (VaR) och Expected Shortfall (ES) estimeras med en icke-parametrisk metod baserad på historisk simulering med ett rullande fönster på 36 månader. Skillnader mellan fondtyper testas för statistiThis paper investigates downside risk in Nordic hedge funds during the COVID-19 crisis of 2020 and the post-pandemic inflation crisis of 2022, comparing them to index funds, balanced funds, and actively managed equity funds. Value at Risk (VaR) and Expected Shortfall (ES) are estimated using a non-parametric method based on historical simulation with a rolling 36-month window. Differences across f

This thesis evaluates three interest rate models the HW1F, HW2F, and CIR++ from a risk management perspective. Through simulation, we examine their ability to generate realistic yield curves, as well as their impact on exposure metrics and CVA in different market environments. The CIR++ model consistently produces the highest and most conservative PFE estimates while also maintaining calibration

This thesis investigates how the integration of post-combustion carbon capture (PCC) systems would affect combined heat and power (CHP) plant performance, using DWSIM, an open- source process simulation tool. A case study on a CHP plant in southern Sweden was conducted, with models simulated for both baseline and CCS-integrated operation. DWSIM proved accurate within a relative error of under 3 %

Seminar date: June 4, 2025 Course: BUSN79 Authors: Ebba Rysjö Lindholm and Tilda Loudd Advisor/Examiner: Niklas Sandell/Liesel Klemcke Five key words: Account Theory, Legitimacy Theory, Crisis Communication, Allra, Financial Scandal Purpose: To examine how Allra, the Pensions Agency, Politicians, and Auditors used external communication to legitimize their actions throughout the Allra scanda

Human Activity Recognition (HAR) from wearable sensors is often constrained by limited labeled data and varying device placements. This thesis investigates a Transformer-based self-supervised approach that learns representations via a masked reconstruction and noise-injection pretext task, followed by fine-tuning on smaller labeled datasets. Experiments on WISDM, REALWORLD, and OPPORTUNITY confir

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
