Med ökande koncentrationer av koldioxid (CO2) i atmosfären kan energieffektiva tekniker för koldioxidinfångning (CCS) bli viktiga för att växthusgasutsläppen ska minska. Rapportens syfte har varit att experimentellt bestämma och utvärdera fyra egenskaper hos lösningar av vatten, dimetylsulfoxid (DMSO) och aminoalkoholen 2-amino-2-metyl-1-propanol (AMP) som ska användas i en pilotanläggning. Vid inWith increasing atmospheric carbon dioxide (CO2) concentrations, energy efficient carbon capture and storage (CCS) technologies could prove important to enable reductions in the global CO2 emissions. The aim was to investigate a novel, non-aqueous, and precipitating chemical absorption system of dimethyl sulfoxide (DMSO) and 2-amino-2-methyl-1-propanol (AMP), which forms solid carbamate salt cryst

The presented thesis focuses on dynamics of capital structure decisions of financially constrained and unconstrained firms listed on Stockholm Stock Exchange. It examines the effect of the global financial crisis on the corporate financing decision. The first chapter introduces the topic, discusses its importance and outlines the contribution to the empirical research. The second chapter the relev

Flooding of urban areas is a worldwide problem as cities grow and the amount of impermeable surfaces increase generating more surface runoff. In the Zambian city of Ndola, the capital of the Copperbelt Province, flooding occurs in some parts of the city especially on Dag Hammarskjöld Drive at the underbridge, which has been flooding every rainy season consecutively for 8 years now. The main object

The production of single cell biomass by the collaboration company in this project for use as a meat alternative is a potential source of sustainable alternatives to functional ingredients for the food industry. With its high protein content, creating a protein isolate from the single cell biomass became interesting and a study of single cell protein functionalities could offer a possibility to in

The growing number of African Presidents on Twitter affirms that media, in all its forms, will always play a fundamental role in contemporary politics. Moreover, based on its face value, the presence of Presidents on Twitter could suggest that citizens are gaining unprecedented access to their president. But, this thesis contends that the newness of Twitter should not blind us into thinking that t

A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was succes

The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values

Despite the increased focus on sustainable urban development both within academia and in urban planning practices, authors seem to agree that we are mostly continuing business as usual and are not embarking on different socio-environmental trajectories. On the contrary, such urban sustainability practices can often lead to processes of displacement and gentrification, thus worsening the conditions

När man jobbar med stora pogrammeringsprojekt är ett av de stora problemen att skriva koden så den går att underhålla. Skriver man kod som är lätt att underhålla är det också enklare att göra tillägg, ändringar och åtgärda problem. I detta projekt har två stora, liknande projekt undersökts för hitta likheter i koden. Om likheterna kan sammanföras till en generisk lösning kommer koden att vara lätWhen working with large programming projects, one of the major problems is to write the code so it can be maintained. If you write code that is easy to maintain it is also easier to extend, change and fix bugs in the code. In this project two large, similar projects were investigated to find similarities in the code. If the similarities could be brought together in a generic solution, the code wo

Non-stationary signals are very common in nature, consider for example speech, music or heart rate. Using the concept of time-frequency analysis this thesis studies the performance of different time-frequency distributions of both simulated and real non-stationary signals. The signals studied are linear and non-linear frequency modulated (FM) signals. Two methods are studied to increase performanc

Traffic accidents cause over 1.2 million deaths, and tens of millions of people are injured or disabled every year. Advanced driver assistant systems and other safety features have the possibility to reduce traffic accidents but do not account for human errors. Studies show that over 90% of all traffic accidents are caused by human errors. One way to reduce human errors is to introduce automation,

Several governments recently adopted strategies to facilitate the development of artificial intelligence (AI), one of the reasons being the pursuit of sustainability – a claim with little scientific grounding so far. In this thesis, I strived to outline the scope of AI’s potentials by showing i) the limits of its theoretical and practical usefulness and ii) the political barriers to using it for s

The development of sports within the European Union (EU) has been blooming the latest century, especially in the football sector, which has been transformed into a multi-billion industry. The development of European football has attracted investors outside the EU into heavy investing in football clubs across Europe. This has enabled purchases of new talents and high profile players for astronomica

The aim is to develop a profound comprehension of what role knowledge plays in the process of integrating the internal knowledge within organizations with the external knowledge that can be found in the surrounding cluster initiatives. This research contains a qualitative case study which was developed by following an interpretative, abductive approach that granted the authors to work with theory

Increase of urbanization and climate change are one of the factors that have been highlighted to influence the change of urban runoff hydrograph. This is resulting in an increase in peak flow within an urban watershed. Downstream flooding is the main problem that arises. To solve this, the sustainable urban drainage system techniques are adopted for reducing peak flow and increase baseflow. This t

The goal of this Master's Thesis is to successfully detect and classify humans in a LiDAR data stream. The focus of the Thesis is on the detection and classification, not on the LiDAR technology. To classify humans machine learning was used and to train the machine learning model we collected our own data and annotated it. A custom software was made for speeding up the annotation process.
