There exists a plethora of research on volunteer tourism, focusing on the various motivations to volunteer and the diverse positive and negative impacts that volunteering has on host communities. However, there is less research on the impact it h

Relativistic attosecond electron pulses by laser wakefield acceleration

Generering av ultrakorta elektronpulser med hjälp av laseracceleration Hur snabb är den snabbaste processen som vi kan observera? Och hur litet är detminsta objektet? Kort sagt så kan vi inte se snabbare än vad ett slutarljus tillåter,eller objekt mindre än den minsta möjliga våglängden. Vad menar jag då med det? Jo, om vi vill ta stillbilder av en galopperande häst, utan att bilden blir suddig,The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained. One such setup, which is used to accelerate electrons, is the l

Bonds Portfolio liquidity risk under stress

Abstract The focus of this thesis is to study and model the capacity of the bank to trade on the bonds market under normal and stressed conditions. This capacity is related to the liquidity of bonds market (ie, the ability to trade) and bank’s trading desks capacity to trade. All banks have different models but all are subject to the validation of the bank in a first place and the EU Central Bank

This is done to give a better starting point when designing slab bridges in future projects. A slab bridge is modelled and analysed with the use of the computer software BRIGADE/standard with parameters su

Leadership and teamwork in safety-critical systems

Devastating catastrophes during the 1980s together with recent years’ fatal accidents, including the Boeing 737 MAX plane crashes in 2018 and 2019, have altogether highlighted the need for researchers’ attention within the field of safety-critical systems. Additionally, as a result from technological advancement and globalization, the prevalent complexity and ambiguity within today’s systems conti

A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. H

The effect of patent boxes on foreign direct investment in Europe

Since Patent Boxes’ first emergence in the 1970’s in Ireland their presence has been fiercely debated. Since their appearance they have grown in numbers and are now present in a multitude of countries across the world. From the perspective of countries and their respective government the reason to their implementation are the following: (i) to incentivize investment in R&D, (ii) to attract (or

Environmental Impact and Stock Returns

Objective: The objective of this study is to examine whether more environmentally sustainable stocks exhibit higher risk-adjusted returns than less sustainable stocks. Method: The question is examined through two-sided significance tests, comparing daily Sharpe ratios for pairwise portfolios consisting of the top and the bottom quantiles of companies as ranked by several sustainability metrics. T

wood among bricks

This project consists of literature research and a design proposal. The concluding discussion evaluates the design as well as the hypothesis of the research. Today, buildings often tend to be short-lived and their potential of recyclability are often limited. Throughout the thesis I am striving to understand wood as a building material. In the theoretical section of the essay, wood is presented f

The Relationship Between Memory Control, Emotion Dysregulation and Subclinical Borderline Symptoms

This study aims to investigate the relationship between memory control ability and a range of borderline personality symptoms in nonclinical participants. It also aims to explore whether emotion regulation skills are a mediator of this relationship. 61 participants completed an adapted, online think/no think experiment using scene-object picture pairs to investigate their memory control. They also

Analyzing V2V signal models in simulated 3D geometry-based stochastic channels

Vehicle to everything (V2x) communication is one of the most researched topics today. The main goal behind this new emerging technology is road safety along with traffic and energy efficiency. Vehicular communications can further be sub-divided into certain types. One such type is vehicle to vehicle (V2V) communication, which is the focus of this thesis. V2V is either Wireless Local Area Network (

Exploring a Model of Modern Prejudice

The present study aimed to explore a proposed model of modern prejudice through the selected variables. Self-compassion, compassion towards others, psychological flexibility, and social dominance orientation were selected as intra-psychological variables (Dimension I) to explore, while ethnic and gender identity were selected as the inter-group relationship variables (Dimension II). 242 participan

The Conductivity-based Peritoneal Equilibration Test - A mathematical modeling assessment

Sufficient solute and water removal are crucial for adequate peritoneal dialy- sis (PD) treatment. However, present clinical tests for peritoneal membrane trans- port characteristics are cumbersome and time consuming. Here, a mathematical model consisting of linear differential equations aiming to describe the complex process of solute and water transport accross the peritoneal membrane, in order

Utvärdering av strategier för provtagning av förorenad mark

Smart provtagning krävs för säkrare bostäder Att låta barnen leka på en övergiven industritomt är en dålig idé, för vem vet vad de hittar där. I marken kan det finnas tungmetaller, kemikalier och övergivna cisterner. När städerna förtätas händer det däremot ofta att bostadshus byggs i gamla industriområden. Hur kan vi veta att det inte leder till okända och farliga rester på barnens lekpark? Vi blBy using statistical analysis of measured data more information can be acquired about a contaminated site in comparison to using the measured data alone. This study shows that the choice of model for the distribution of the contamination is vital in getting a reliable estimation of the contaminated area. By simulating exponentially decreasing contaminant distributions around a point source and sub

Social Distancing AI: Using super-resolution to train an object detection model on low resolution images

This paper addresses the following hypothetical situation: suppose that we want to train an object detection algorithm but that only low resolution data is available. As a tentative solution to this problem, this paper suggest to first super-resolve the low resolution data to obtain higher resolution data that is then fed to the object detection algorithm. Super-resolution is a technique that take

Real-world low-light image enhancement using Variational Autoencoders

Low-light image enhancement is a hard task mainly due to the amount of noise and little information stored in the dark image. In this thesis project we develop a method for low-light image enhancement based on a Conditional Variational Autoencoder (CVAE). The CVAE is a deep learning model trained with a specific objective function (ELBO). A CVAE can be implemented as a variant of a U-Net utilizing
