VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample, and provides instantaneous access to a broad dynamic range, 1-120 meV within each ESS period. The sh
Idag kopplas allt fler enheter upp på Internet, vilket effektiviserar såväl enhetshantering som kommunikation mellan enheter. I hemmiljöer kan användare styra enheter genom att förse dem med beskrivande namn, som till exempel "högtalare vardagsrum". Så länge antalet enheter är begränsat är en sådan lösning ofta tillräcklig. I ett fall med ett stort antal enheter måste användaren dock hålToday, an increasing amount of physical devices are obtaining Internet connectivity for more efficient management and device communication. In home environments, users may manage devices by providing them descriptive names such as "living room speaker". For a limited set of devices such a solution is often sufficient. However, in a case where one wants to individually manage a very high
Wildfires pose a serious threat to communities in different parts of the world, mostly in regions with a warmer climate. Due to the increased urbanization next to the forest and climate change, they are currently an issue to be addressed also in other parts of the world. The purpose of this thesis is to provide a first step in the direction of creating a holistic Vulnerability Assessment Method (V
A Turing model for pattern generation on Lady beetles is considered. This motivates the construction of numerical algorithms for solving reaction-diffusion equations on the sphere. By applying a Galerkin approximation in space, and the implicit Euler method for timestepping, the equation is fully discretized. Convergence orders are proven for this scheme. To obtain a more efficient time stepping a
Fluid biomarkers are revolutionizing the diagnosis and management of neurodegenerative diseases by enabling earlier diagnosis and disease monitoring. In particular, blood-based biomarkers have emerged as a minimally invasive and scalable alternative to cerebrospinal fluid analysis. Recent advances in blood-based tau biomarkers have shown high diagnostic accuracy for Alzheimer’s disease (AD). Other
The most prevailing hypothesis regarding mechanisms behind specific language impairment today is the hypothesis of general limitations of processing capacity. Such an hypothesis can hardly be tested by available language assessment tools, especially not by instruments in use for clinical assessment of the lexical-semantic domain in children. Reduced naming speed is by some researchers considered a
The power of attosecond pump-probe spectroscopy combined with advanced detection schemes, such as photoelectron/ion coincidence spectrometers and time-resolved photoelectron emission microscopy (PEEM), can be unleashed by properly accounting for the repetition rate of the source. In this work, we present a high-repetition rate (200 kHz) attosecond pulse source that opens up for exploring phenomena
We demonstrate a novel timing tool for Free-Electron Lasers to determine the delay between an attosecond pulse train and infrared pulse with sub-optical-cycle resolu-. tion.
Objectives The purpose of the thesis is to investigate how a new logistic set-up can lower the transportation cost of OEM articles. Four objectives are identified to that end: identify the OEM articles, map their flow, create simulation tool and examine what logistics set-up is suitable. Background The increasing rate of globalization has put immense pressure on the world’s infrastructure. As a re
Abstract Title: Ethanol for Scania’s future – A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne – Department of Business Administration, Lund University Jonas Holmborn – Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist – Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominati
Deep reinforcement learning has been shown to be able to solve tasks without prior knowledge of thedynamics of the problems. In this thesis the applicability of reinforcement learning on the problem ofproduction planing is evaluated. Experiments are performed in order to reveal strengths and weak-nesses of the theory currently available. Reinforcement learning shows great potential but currentlyon
Artificial lighting energy consumption in buildings can be reduced by efficiently daylighting the occupied spaces. Artificial lighting comprehends 21 % of the total energy consumption in tertiary buildings (Swedish energy agency, 2015). In many buildings daylight access is neglected, thus redirecting daylight is an efficient strategy to optimize daylighting while keeping the same area of openings
Empowerment is a well-known slogan that symbolizes the struggle of marginalized groups against social injustices. This thesis is another contribution to the field of empowerment, addressing the issue of misusing public funds. Public Expenditure Tracking Survey, PETS, is a methodology that has been carried out in order to fight against this issue. In this study, the aim is to scrutinize whether PET
Arbetsrelaterade skador orsakar personligt lidande och ekonomiska förluster för både företag och privatpersoner. Repetitivt arbete och statiska arbetsställningar med armarna kan leda till belastningsskador i axel- och halsregionen. Detta examensarbete har haft som syfte att utveckla ett mjukt bärbart robotsystem med Bioservo Technologies Soft Extra Muscle (SEM) teknik, som ska ge assistans vid lyfWork related injuries causes personal suffering and economic loss for both companies and individuals. Repetitive work and static postures with the arms can lead to musculoskeletal disorders (MSD) in the shoulder and neck region. This thesis set out to develop a wearable soft robotic arm lifting system using Bioservo Technologies’ Soft Extra Muscle (SEM) technology. The objective was to develop a f
This is the report for a master thesis work which concerns the challenge of automating a reach stacker. A reach stacker is a vehicle that lifts and moves containers. This report should be seen as a preliminary study which handles automation concepts, simulations and sensors. Research questions answered are: Which areas would benefit most from driver assistance, What kind of control is needed for t
The goal of risk and vulnerability research is to reduce the harm done by disasters. A disaster is a combination of a natural hazard and a vulnerable society. Understanding vulnerability is vital to reduce disaster risk, or the potential of losses in property or life. Vulnerability is often divided into a technical, relating to buildings, infrastructure, and so forth, and a social which concerns t
This is the story if a beginning, a beginning of a journey to the unknown, to find my own path, because paths are made by walking...but you have to do the scariest part: start to walk. The project is presented as a handbook for the next generations of students that want to start their own office, answering the same questions and difficulties that I had during my trip. The idea of this Master pro
The purpose of this study was to contribute to increased awareness and understanding of how actors collaborate to solve complex societal problems. The study also intends to contribute to increased knowledge of the relevance of theory network governance in describing collaborative processes. A third purpose was to study if Forward Malmö has the potential to contribute to the work on social sustaina
Acknowledging the importance of government communication and government trust, this study aims to investigate how a government organisation can utilize a social media platform such as TikTok to develop and maintain a high level of public trust and build strong, long-lasting relationships with its citizens. The Chinese Public Security Bureau's (PSB) TikTok communication strategy was chosen as t
