The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of ℒ = 2 × 1034 cm-2 s-1 was routinely achieved at the start of fills, twice the design luminosity. For Run 3, accelerator improvements, notably luminosity levelling, allow sustained running at an instantaneous luminosity of ℒ = 2 × 1034 cm-2 s-1, with an a

Despite the successes in the use of artificial intelligence systems for image analysis, in certain critical applications, the final decision-making should remain with the human operator. To facilitate the working conditions of an unmanned aerial vehicle (UAV) pilot during prolonged missions, an auxiliary narrow-angle video camera is installed on board the UAV. This camera can be positioned indepen

Explaining the maintenance of genetic variation in fitness-related traits within populations is a fundamental challenge in ecology and evolutionary biology. Frequency-dependent selection (FDS) is one mechanism that can maintain such variation, especially when selection favours rare variants (negative FDS). However, our general knowledge about the occurrence of FDS, its strength and direction remai

According to Art. 58 VAT Directive digital services are to be taxed at the place where the customer resides. The Implementing Regulation provides certain presumptions for suppliers to determine that place. These presumptions are analysed in this thesis regarding their actual compliance effort for companies, as well as the implementation of the destination principle. But before, the conditions and

Den process där nya länder går med Europeiska unionen (EU) kallas utvidgning. Det har haft en central roll i unionens utveckling. Sedan grundandet har EU vuxit från sex till tjugosju medlemsländer, under totalt sju utvidgningsomgångar. För närvarande är fem länder kandidater för medlemskap: Montenegro, Serbien, Albanien, Nordmakedonien och Turkiet. Kosovo och Bosnien och Hercegovina är potentiellaEnlargement, the process whereby countries join the European Union (EU), has had a key role in the Union’s development. Since its founding, the EU has grown from six to twenty-seven Member States, in a total of seven enlargement rounds. Currently, five countries are candidates for membership: Montenegro, Serbia, Albania, North Macedonia and Turkey. Kosovo and Bosnia and Herzegovina are recognised

First, the thesis establishes that non-refoulement obligation is jus cogens norms. Before establishing the peremptoriness of the given legal norm, the account of the concept of jus cogens is proposed within which such elevation occurs. The argument suggests that jus cogens non-refoulement obligation complemented with the various conceptual and normative objections undermine the conceptual viabilit

There is a growing interest in integrating indoor and outdoor spaces and our experiences on both sides. Nevertheless, despite being a constant topic in architectural research, there is little academic work that shows the role of furniture as great tools for creating that connection. This degree project aims to show the enormous potential of furniture to be a useful tool to connect indoor and outd

Phosphate is fundamental for optimal growth and reproduction for plants. However, due to low solubility, not all phosphorus in the soil is available to the plant. It has recently been discovered that plants can take up complex phosphate-containing organic compounds, such as phospholipids. This depends on membrane transporters, more specifically lipid flippases. In the model plant Arabidopsis, the

This thesis examines the possible transjudicial interaction that may arise between the ICC and the IACtHR with regard to the interpretation of the crime of enforced disappearance of persons. This potential scenario of jurisprudential cross-fertilisation is considered on the fact that both, the IACtHR and the ICC exercise jurisdiction ratione materiae over the crime of enforced disappearance, there

Societal resilience is fundamental for navigating sustainable development while being seriously challenged by misinformation and disinformation in the post-truth era. The thesis’ purpose is to explore how AI-driven truth technologies can be developed and utilised to mitigate mis- and disinformation. Three research questions are answered to illustrate the potential of truth technologies by (1) clar

Wrist fractures are a prevalent injury in Sweden. While most patients recover within a year, approximately 5000 patients a year experience significant long-term pain and impaired wrist function. Current rehabilitation methods lack the capacity to objectively measure post-fracture wrist function. Proprioception, the awareness of the body in space, is crucial for wrist function but remains challengi

Sweden and Europe aim to be carbon neutral by 2045 and 2050 respectively. Upgrading the existing building stock has been identified as having great potential in assisting to realise these goals. This aged, energy inefficient building stock is poised for renovation towards carbon neutrality, and the investigation of the cost-effectiveness and possibilities for these were the main aim of this study.

The European Spallation Source (sv: Europeiska Spallationskällan) kommer att bli den mest kraftfulla spallationskällan i världen när den är i drift vid full kapacitet. Neutronerna som används av vetenskapsmän och ingenjörer är spallerade från ett roterande hjul av volfram, som blir bombarderat av accellererade protoner. Hjulet, även kallat målet, upplever värmeutveckling under spallationsprocessenThe European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. The wheel, also called the target, develops heat in the process, and is therefore cooled by a helium cooling system. The target primary cooling sy

The Lyapunov exponent is a wide-reaching and useful tool for the analysis of chaotic systems. In this thesis, we go through the necessary mathematical and computational framework to extract both the maximum Lyapunov exponent and Lyapunov spectrum for the double pendulum system. An analysis of the maximum exponent through time and the validity of Liouville's theorem were conducted, showing good

In the framework of this thesis, the optimization of the etching process of GaN for FinFET applications has been investigated. FinFETs are transistors with a vertical architecture in the shape of fins. These fins are fabricated by etching a pattern into a GaN substrate. The etching is carried out in two steps, a dry etch and a wet etch. In this thesis, these etching steps have been carried out whi

The building industry, like many others, are currently experiencing the effects of the digitalization, and the increased spread of smart buildings is a result of this. Much research has been done on smart buildings and their predecessors intelligent buildings, but there is limited research available on how entrance systems should be designed for smart buildings, especially regarding their connecte

Climate change is a long-term challenge that requires urgent actions. An increased amount of greenhouse gases in the atmosphere, causing changes in the climate system such as melting glaciers and extreme weather conditions, are correlated to economic growth. To mitigate climate change, there is a need to evolve efficient strategies to reduce greenhouse gas emissions from companies within all branc

Purpose and research question: The purpose of the study is to examine the effect ESG disclosure exerts on a firm’s propensity towards public or private debt. Methodology: For the panel data, pooled OLS and fixed effects models are applied. A quadratic term is introduced to test for non-linearity between bond debt ratios and ESG disclosure scores. An instrumental variable approach and a sharp regre
