The aim of this master's thesis is to establish material models for three rubber materials using macroscopic data collected using Digital Image Correlation, DIC. DIC is a non-contact optical technique for measuring strain and displacement in a material by tracking points on a material during the deformation process.\\ The rubber materials are tested in both uniaxial tension and compression, fr
Traffic congestion is a persistent problem in modern urban environments, causing delays, increasing pollution, and negatively affecting the quality of life of millions of city dwellers. As urban populations grow, the need for intelligent traffic man- agement systems becomes more pressing. This thesis presents a novel approach to real-time traffic management using edge computing in conjunction w
In today's society, much energy is used and all energy use (e.g. heat, electricity) affects the environment. Greenhouse gas emissions from energy affect the climate of the earth and increase the natural greenhouse effect. Environmental impact because of energy use causes both local and global problems. Efficient energy use in buildings is a prerequisite for dealing with climate issues and in t
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 master’s thesis report describes the development of a new system for control and monitoring of a helium liquefaction plant which has been carried out at Kryolab, Lund University. At the plant, helium gas is purified and then cooled in several steps until it condensates. The plant is very similar to the ones constructed today, but Kryolab wished to replace the outdated control system. The new
A model of the Swedish power plant Mälardalen Energi, developed by Solvina AB was simulated in Dymola with different types of control strategies in order to evaluate if they could improve the operational flexibility of the plant and, thus, its ability to deliver frequency control to the Swedish power grid. Several different control strategies and process modifications were tested and compared to p
The Light Dark Matter Experiment (LDMX) is a fixed target experiment that will search for dark matter, but is still in the development phase. An important aspect for the experiment is the discrimination of signal and background events. Here this signal and background discrimination is inspected using a machine learning technique called a Boosted Decision Tree (BDT). This is done using Monte Carlo
As people and organizations make themselves more vulnerable on the internet, there is a significant increase in cybersecurity threats. Due to this, organizations and individuals think more about their actions online. However, organizations are constantly improving their methods, when handling confidential data and are developing an understanding of protecting consumers from such exposure. This res
Cerebral Palsy (CP) has an impact on muscles and movement. This happens due to brain damage before the age of two years. Either sometimes before birth, during childbirth or after birth. According to hjarnfonden.se, 200 children are added annually in Sweden with CP. People living with CP have these weaknesses for the rest of their lives. CP is not progressive disorder, that means brain damage can’
Begreppet adaptation to the adverse effects of climate change är relativt nytt in internationell miljörätt. Begreppet adaptation är inte definierat i UNFCCC. Den här uppsatsen analyserar adaptation i ljuset av begreppet reparation i internationell sedvanerätt. Uppsatsen undersöker vad begreppen adaptation och reparation har gemensamt. Kan adaptation i UNFCCC ses som en möjlig utveckling eller förlThe concept of adaptation to the adverse effects of climate change is relatively recent in international environmental law. Adaptation is not defined in the UNFCCC. This paper attempts to address adaptation in the UNFCCC from the perspective of reparation under customary international law. It investigates what the concepts of adaptation and reparation have in common. Could adaptation in the UNFCCC
In a GIS system, the need to encode geospatial data without standardized cartographic representations, such as population data, weather information, etc., on top of a map is common. This can be done with a layer on top of a base map, with the effect that the base map is partially or fully hidden. Reducing the opacity (or its equivalent - increasing the transparency) of this overlay data layer is a
This research explores the effect of the European Union’s Recovery and Resilience Facility (RRF) on multi-level governance (MLG) by adducing the theory of postfunctionalism’s explanatory power. Previous MLG research on the COVID-19 crisis found alternating national centralisation/decentralisation movements due to crisis management. Scrutinising the watershed RRF offers novel insights into MLG’s de
The objective of this thesis is to analyse how masculinities inside the SwAF are manifested as well as how these affect the civil life of male soldiers. This is achieved by using a set of individual case studies where semi-structured interviews serve as the main data. To study masculinities I chose to use Connell's concept of hegemonic masculinities. In addition to this, I used Annika Kronsell
The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. However, with continued device scaling, the performance of Integrated Chips (ICs) starts to deteriorate, making it essentia
In this thesis, I discuss the difficulties Ukrainian refugees face in accessing and integrating into the Swedish labor market, the role of civil society organizations (CSOs) in Sweden with regard to the labor market integration of Ukrainian refugees, and the policy hindrance and CSOs’ limitation in achieving their goal for Ukrainian refugees. This thesis gathers qualitative data using semi-structu
Den här studiens primära syfte är att jämföra och utvärdera två medborgardialogs metoder. De två metoderna är samrådsmöten och Public participatiory GIS (PPGIS). Samrådsmöten är en etablerad metod inom medborgardialog för samhällsplanering i Sverige. Uppsatser syftar till att pröva hypotesen om PPGIS är en effektivare metods för medborgardialog. Uppsatsen utvärderade först de två metoderna med hThe primary purpose of this study is to compare and evaluate two public participation methods. The two methods are public meetings and Public participatory GIS (PPGIS). Public meetings are an established public participation method for urban planning in Sweden. The thesis aims to test the hypothesis if PPGIS is more effective as a public participation method. The thesis first evaluated the two me
International and national carbon reduction plans and targets have constituted the subject of a copious amount research in recent years. Concurrently, the number of cities, regions, companies and communities that have set ambitious targets for renewable energy and energy efficiency has been growing. Among these actors, rural communities in the developed world and their efforts toward the transitio
Sentinel-2 based data provides interesting opportunities for land monitoring and applications in agriculture. High-Resolution Vegetation Phenology and Productivity (HR-VPP) is derived from Sentinel-2 data and offers up to 13 metrics. These metrics have a high spatial resolution (10x10m) and enables the possibility for in-field agricultural monitoring. The aim of this study is to evaluate four of t
This thesis’ main goals were to provide accurate forecasts and informative physical parameter estimates for energy use of the district heating in the Tingbjerg neighborhood, Copenhagen. Our work is aimed as a contribution for future work towards efficient on-demand energy production. We applied Dynamic Double Machine Learning to estimate the causal effects of weather observations on energy use. Th
