Det blir allt vanligare med solceller hos konsumenter uppkopplade till lågspänningsnätet och stora mängder solel leder till överspänningar i elnätet. Denna överspänning är en av faktorerna som begränsar mängden solel i ett nät/område, och måste därför kunna regleras. Av flera olika metoder så hanterar detta arbete en undersökning av scenariot med spänningsreglering via reaktiv effekt, främst med P

In nineteenth-century literature, the heroine is often a young woman growing up and learning about the restrictions of gender and society. If she learns from the mistakes she is inevitably going to make, she may be rewarded … with a suitor? How does this correlate, who are the heroines and who are the suitors? This essay aims to answer these questions, along with evaluating parents in literature a

With the increased number of technical innovations in soccer and the progress in the field of AI, this thesis investigates the possibilities to detect if a player is in offside position using deep learning and video recordings from soccer games. A method to create a 3D reconstruction of the players in the scene is proposed and evaluated. The arguments for using a 3D reconstruction is that it intro

This study aims to contribute towards the existing literature of volunteer tourism by evaluating the impacts that volunteering has on career progression. 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

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

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

Detta arbete behandlar överslagsdimensionering av plattrambroar, och syftar till att undersöka hur kostnads- och miljöaspekter påverkas av ramens tjocklek för vanliga spännvidder och fria höjder. Detta för att ge ett bättre utgångsläge vid dimensionering av plattrambroar för framtida projekt. En plattrambro modelleras och analyseras med hjälp av programvaran BRIGADE/Standard och parametrarna spännThis study aims to make a preliminary design of an integral bridge with frame abutments, and to see how the frame’s thickness for common spans and heights affects cost and environmental aspects. 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

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

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

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

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

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

Denna uppsats syftar till att bidra med ökad kunskap kring hur värde skapas internt i människobehandlande verksamheter, samt dess påverkan på arbetsmiljön och vidare det externa värdeskapandet. Fokus har följaktligen varit på att skildra medarbetarnas perspektiv och redogöra för hur de upplever att kontroll och handlingsutrymme påverkar deras förutsättningar i skapandet av värde på arbetsplatsen.

Purpose – Sudanese supply chains were greatly affected by the US sanctions from 1997 and until today. This research aims to understand the effects of US sanctions on the Sudanese practices of sourcing, procurement, and transportation. Additionally, the research aims to discover the way through which the US sanctions were avoided by the studied Sudanese practices. Finally, the research tests a hypo
