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
This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. The thesis focuses on pulse characterization, through use of frequency-resolved optical gating (FROG), of
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’
The notion of human rights is built on the fact that they are universal rights and thus applies to everyone without exceptions. Despite this irregular workers are denied their labour rights and their human rights due to the fact that they are living in a country unlawfully. The states use methods as regularizing irregular migrants or enabling tougher sanctions against irregular migration in order
Over the past decades, sustainable production and consumption pattern has been addressed on a global level. Business is a powerful stakeholder in the development of sustainable consumption and production systems as it represents a great proportion of competence, resources and mechanisms (Charter, Gray, Clark and Woolman, 2008). The global approach toward achieving sustainable production and consum
Dividing complex systems into smaller components that are easier for humans to comprehend and manage, is a wide spread method in software design. As systems grow more complex, the task of solving the different dependencies and constrictions of the various components in a system, and create a stable and valid composition naturally also gains complexity. Various tools have been constructed to manage
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
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
The combined global emergence of a sustainable development discourse and Swedish policies requiring municipalities to rapidly build new housing have led Lund to develop Brunnshög. This pioneering megaproject balances urban expansion with high sustainability ambitions. Through the lens of urban political ecology, this thesis aims at analysing Brunnshög’s dominant sustainability narrative as told by
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
In Skåne, Southern region of Sweden, where the idea that no Sámis live in the area is largely spread across the Swedish population, the few Sámis living there find themselves navigating their ethnic identity, between performativity, agency, and making use of the policies implemented at a national level. In a context of ongoing decolonisation of the Sámis and their lands, official institutions such
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
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
This thesis is inspired by the lack of academic discourse on human rights aspects of human space settlement. It builds on the ever-growing literature on colonizing Mars and the ongoing public debate on the benefits versus disadvantages thereof. Taking on a critical approach, this thesis opens up a conversation on power, universalism, and legitimacy within space exploration, questioning both the on
A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. The detector uses multiple layers of solid coating containing 10B4C on the edges of a vo
Acknowledging, the research gap within sustainability transitions in analysing the local scale of transition processes, this work primarily, seeks to contribute to sustainability transitions studies by identifying the main factors that are enabling and hindering the materialization of low carbon mobility in Cuenca, Ecuador. The use of a case study as a research strategy and the nature of the rese
The behaviour and fate of stem cells is governed by the material properties of their surrounding microenvironment. Hence emulating the extracellular matrix poses as an attractive target for tissue engineering endeavours to create a stem cell substrate. Currently, the knowledge of the material properties is mostly limited to the macroscopic level which considerably limits the understanding of tissu
