Experiments at particle colliders provide experimental verifications of theories in particle physics, and allow to search for new particles. Computer programs are used to simulate particle collisions. Those so-called event generators can be used to prove theories and compare their results to actual collisions from the colliders. Even though those programs run on powerful computer systems, the even
Purpose: Supply chains lack transparency due to their complexity and fragmentation. Blockchain technology is increasingly expected to revolutionise businesses and promises to create trustworthy transparency. This study aimed to investigate the potentials of blockchain technology for supply chain transparency beyond the growing glorification. Methodology: The potentials, as well as immaturities and
Post-harvest losses in the himalayan regions of Nepal and Bhutan are high, and current drying methods are in need of improvement. This report improves on a previously developed solar dryer design and evaluates thermal storage solutions for the ’SolarFood: Reducing post-harvest losses through improved solar drying’ project. This report uses experimental measurements to compare different dryer confi
To mitigate climate change and reach Sweden’s goal of becoming carbon neutral by 2045, or at an earlier stage of 2030 for 23 Swedish cities, urgent action is required to reduce greenhouse gas emissions. Due to the building sector’s significant contribution to carbon emissions, a crucial aspect in achieving these goals is improving the energy efficiency of existing buildings, as most of these will
The MAX IV synchrotron radiation facility in Lund is designed to produce bright and high-energy X-ray radiation. One important component of achieving this is to keep the electron beam inside the storage rings centered and stable. The aim of this thesis was to develop an MPC (Model Predictive Control) that can accomplish this task more robustly than the currently commissioned I-controller. A contro
Reinforcement learning is one of the three main paradigms in machine learning, which is increasingly used as a method to approach scientific problems. In this thesis, we introduce and use reinforcement learning to find the optimal parameters of a numerical solver. We first motivate that solving the linear systems can be done by solving initial value problems. These initial values problems can the

Spectroscopy serves as a vital tool in both scientific research and industrial applications. In spectral analysis, baseline correction is important in order to be able to efficiently extract essential features. Several algorithms for baseline correction have been developed, including Asls (Asymmetric Least Squares algorithm), arPLS (Asymmetrically Reweighted Penalized Least Squares algorithm), air
The MAX IV facility is a 3rd generation state-of-the-art synchrotron light source currently under construction in Lund, Sweden. The MAX IV 3 GeV storage ring has a large negative natural chromaticity, which has to be corrected to positive values to prevent head-tail instabilities. On the other hand, high linear chromaticity can lead to a large tune footprint limiting Touschek lifetime. Therefore,
The European Union is often criticized for its democratic deficit. This criticism has led to a process of including civil society in European governance through consultations, round table discussions and civil dialogue. These steps of inclusion have been oriented towards organized civil society. This study explores the European Citizens’ Initiative (ECI) a new tool for participation available to a
In this article, I estimated the impacts of American economy on Swedish economy from long-term perspective with using the standard form vector autoregression model (VAR model). In order to obtain a comprehensive point of view, I decided to investigate the relationship between these two countries from three aspects, living and working environment, export and import volumes and stock market. After g
We have made a thesis about Collaboration for Innovation in the Öresund region from a Swedish perspective. The thesis is taking both regional and corporate aspects into consideration when studying this subject. The empiric material is based upon several interviews with persons having knowledge about our subject as well as a web survey including 49 companies situated in the Öresund region. We have
This is a case study that aims to explain the adoption of the Victims’ Law by investigating the transnational advocacy networks’ work for the rights of the victims of the armed conflict in Colombia. Theories of transnational advocacy networks and opportunity structures are applied in order to understand the long term advocacy work for the victims’ rights, but also to explain their influence on the
The water footprint assessment framework aims to illustrate the full impact of water consumption in the whole life cycle of a product, from direct water extraction to water pollution. The framework provides a comprehensive indicator for water resources which, if used with care, can provide detailed information about the different impacts of water consumption in order to aid with water stewardship
Neuropeptide Y (NPY) acts via several distinct receptor types. The aim of the present study was to examine which NPY receptors are coupled to inhibition of parasympathetically-mediated contractions of the isolated guinea pig trachea. Electrical field stimulation of tracheal rings evoked a rapid twitch, which was abolished by atropine (1 microM). NPY, the structurally related hormone peptide YY (PY
Social and technological innovations are commonly seen as either being induced from the ‘top-down’ – e.g., by policymakers – or evolving from the ‘bottom-up’ – e.g., by consumers. Instead, a ‘middle-out’ perspective (MOP) focuses on agents of change that are located in the middle, between the top and the bottom. Janda and Parag (2013) and Parag & Janda (2014) describe how middle actors include
The breakup of the L-chondrite parent body in the asteroid belt 466 million years (Ma) ago still delivers almost a third of all meteorites falling on Earth. Our new extraterrestrial chromite and 3He data for Ordovician sediments show that the breakup took place just at the onset of a major, eustatic sea level fall previously attributed to an Ordovician ice age. Shortly after the breakup, the flux
