Världen står införstora utmaningar när vårt klimat förändras. Varmare, blötare somrar, köldknäppar och höga vindar är bara ett par exempel. Samtidigt tas krafttag för att minska människans påverkan på klimatet, där transporter utgör en stor del. Fler resor måste gå på järnväg, och fler än någonsin vill resa med tåg, det mest miljövänliga alternativet. Dock finns stora risker och sårbarheterThe world faces significant climate changes with potential societal disruptions and risks to critical infrastructure like railways. This study explores the topic of climate change, extreme weather, and changing travel patterns for Swedish railways. It describes the vulnerability of the railway system with emphasize on the need for climate adaptation. It also includes a comparison between Swedish T

In order to manage risks at the municipal level, in Sweden, there is legal requirements to create a risk and vulnerability analysis and an action plan. The question that started this work is what is the quality of judgments made in these reports, eventually land on focusing on probability assignments, and if there is anything that can make them better. To answer this, it was necessary to collect r

Med inflytande av egen erfarenhet av en uppväxt i ett socioekonomiskt utsatt område, väcktes mitt intresse att undersöka anledningarna till att miljonprograms kvarter ofta utvecklade höga nivåer av brottslighet, skadegörelse, hög beroendegrad av förmåner och andra sociala och ekonomiska problem. Men framför allt ville jag ta reda på hur detta kunde förändras. Denna rapport syftar till att via erfaInfluenced by my own experience growing up in a socioeconomically deprived area, my interest was sparked to investigate the reasons why million-program neighborhoods often developed high levels of crime, vandalism, a high dependency on benefits, and other social and economic issues. More importantly, I wanted to find out how this could be changed. This report aims to answer how a socioeconomically

This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good eCost efficient membrane filtration can make textile recycling more sustainable by separating the dyes from the solvents. To make the textile industry sustainable it must become circular by recycling textiles. Currently textile recycling use, discard and emit water, chemicals, water-based solvents, and dye when these could instead be used cyclically. For example, the solvents used to remove the dye

Forskning inom militär etik har påvisat att militär personal visar en mer positiv inställning gentemot oetiska attityder i krigszoner, vilket kan härledas till deras mörka personlighetsdrag och moraliska principer. Denna studie undersökte relationen mellan militär etik, personlighetsdraget välvillighet, och aspekter av moraliska principer. Genom att använda femfaktormodellen, moralfundamentsteorinResearch in military ethics has shown that military members demonstrate a more positive attitude towards unethical behavior in warzones, which can be attributed to their malevolent personality traits and moral foundations. This study investigated the relationship between military ethics, the personality trait agreeableness, and aspects of moral foundations. Utilizing the Big Five personality model

Du har kanske hört talas om att bananer är radioaktiva eller känner till att för mycket radon kan vara ett problem i svenska hem. Fast hur mycket vet du egentligen om bakgrundsstrålning? Många har nog hört ordet förut men visste du att man utsätts för radioaktiv strålning, eller joniserande strålning som man egentligen borde säga, hela tiden? En genomsnittssvensk utsätts för en stråldos på mellan Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. The aim of this project was to the develop a method for retrospectively analysing the annual discharge of dissolved inorganic 14C. A

This thesis examines the influence of payment methods on bidder stock returns during acquisitions in the tumultuous United Kingdom market conditions from 2018 to 2022, specifically whether the choice between cash or stock payments yields any different cumulative abnormal returns for the acquirers. Additionally, this thesis investigates whether the financial industry deviates from other sectors in

Research on violence on digital platforms have focused on how perpetrators exploit ano-nymity, Geo-tracking, blackmail and other tools to abuse a victim online and very little re-search has been done in regards on how society and organisations protect the victims. This thesis explores what organisations that work with domestic violence victims experience when it comes to digital technology. Four u

Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. Vanillin and its derivatives have shown promise as eco-friendly substitutes for con

Lindholmens Bathhouse – a reproduction of a bygone era? This thesis discusses the development of generative AI and if we can get an extended understanding of an AI image linked to an already existing place. The essay is divided into two parts, one which focuses on trying to decode the chosen AI image based on Roland Barthes semiotics and the second part which deals with the AI image and with mean

Denna studie undersöker själv-avhumanisering och dess roll i samspelet mellan politisk extremism och radikalisering. Vår frågeställning var “Påverkar själv-avhumanisering på gruppnivå respektive individnivå samspelet mellan politisk extremism och radikalisering?" Vi ville också bekräfta att det finns ett samband mellan radikalisering och extremism, och påverkar själv-avhumanisering på grupp-

A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an expone

Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. One of these processing conditions is the annealing t

Emotional vocabulary enjoys a processing advantage, with the emotional salience of a word detected at 200 ms post-presentation or earlier, signalling selective attention to its affective properties. An individual’s affective state also impacts attention and, by extension, affects processing. This study investigates whether and how preferential processing of emotional valence is modulated by mood.

We introduce Mix Encoder, a novel self-supervised learning framework for deep tabular data models based on Mixup [1]. Mix Encoder uses linear interpolations of samples with associated pretext tasks to form useful pre-trained representations. We further analyze the viability of tabular self-supervised learning by introducing VIME [2], an established representation learning framework for tabular dat

This student thesis explores the risks associated with integrated photovoltaic (PV) façades and the challenges associated with implementing them in construction projects. Underlining the significance of curbing greenhouse gas emissions and the potential for PV facades to transform the construction sector, concerns regarding fire safety have surfaced as a primary obstacle. The thesis aims to answer

Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. The main purpose of this study was to measure the baseline SOC stock for a larger research projec

Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. This project investigated the geometrical accuracy of Radixact

The market has existed since the time people started trading. In the Czech Republic, and in Ostrava, the history of markets was influenced by a number of circumstances during the past which led into the present situation in the city. In 2015, the market hall in the center of Moravian Ostrava and Přívoz was closed and demolished and since then the 3rd largest city in the Czech Republic still does
