In this report we study systems governed by the Saint-Venant shallow water equations interacting with boundary conditions including control. We derive closed form formulas for the open-loop behavior. These formulas rely on first, second and third order approximations which are based on a perturbation that we develop. Properties of these solutions are studied and comparisons with existing non-linea
Background The EU’s 20-20-20 targets determine that Finland’s share of energy consumption from renewable energy sources is to be 38 % by 2020, a target that the government intends to reach by expansion of wind power. The government has a beneficial feed-in tariff in place as an incentive for rapid wind power expansion, which has made both domestic and international developers evaluate the business
Resultatet av studien visar att det finns komparativa skillnader på tre olika nivåer. (1) På den nationella nivån framhålls den för arbetstagaren extensiva svenska arbetsrätten och den generösa sjukförsäkringen som potentiella orsaker till att sjukfrånvaron är högre i Sverige än i Danmark. (2) På den organisatoriska nivån konkluderas att de svenska organisationerna har starkare tonvikt på hälsa oc
This study focuses on the human factors associated with elevator use during evacuation in residential buildings. An online survey is conducted to explore seven factors that may influence people’s choice of elevators in China and the United Kingdom, including floor height, waiting time for elevators, crowd density in front of elevators, mobility limitations, instructions, fire location concerning p
This master's thesis explores the potential of integrating floating wind power into Power-to-X (P2X) megaprojects, with a focus on maximizing the output of chemical energy carriers through optimal energy mix strategies. The study evaluates the economic viability and technological efficiency of combining floating wind turbines with photovoltaic panels and battery energy storage systems (BESS) i
Ultrasound optical tomography is a medical imaging modality that combines ultrasound and light to improve the low resolution of optical imaging caused by scattering in tissue. Photons passing through an ultrasound pulse have a probability of being frequency shifted. By filtering out these photons and analysing them, images with optical contrast and ultrasound resolution can be obtained. In this t
This thesis considers solitary standing wave solutions to the Davey-Stewart-son equation, which is a model for surface waves on a body of water in three dimensions. In a special case, the Davey-Stewartson equation is reduced to the well-known non-linear Schrödinger equation with cubic power which is known to have a countable familiy of radial standing waves. One of the aims of this thesis is to in
Purpose – The purpose of this study is to uncover what motivational factors exists for companies to use co-creational methods. It also aims to recognize what beneficial factors can come from using these methods. The restriction of using social media depending on industry or size of company will be reflected upon. The main research question is “What motivates companies to use customer co-creation a
The yield curve of a collection of debt contracts describes the yield of the debt contract as a function of the length-to-maturity of the contract. It turns out that these yield curves provide useful insight about the economy as a whole and can, for example, be used to predict short-term economic downturns. Therefore, it is of utmost importance that financial analysts and decision-makers are able
Safety, privacy and comfort are elements that need to be improved on Swedish shelters. Since several homeless individuals often share bedrooms, it is not uncommon for them to be exposed to violence, harassment and theft or a generally disturbing environment during their stay. These are all contributing factors to an increased difficulty in getting out of homelessness. Enfold is a flexible w
Molecular imprinting technology is a field where polymer technology is utilised to synthesise high affinity particles, much like antibodies. This project has dealt with the imprinting of the neurotransmitter molecules serotonin and histamine. Serotonin polymers were synthesised using methacrylic acid and acrylamide as functional monomers relying on hydrogen bonding for the imprinting effect. None
The study aims to explore the relationship between migration and the quality of education, considering the lowering quality of higher education in Georgia as one of the main ‘push-factors’. The research itself tries to identify the main motivations of why Georgian students migrate. Furthermore, the main gaps and disadvantages of the higher education system of Georgia are investigated. The findings
Finns det något utpräglande för debutverk eller är debutverk snarare en utgångspunkt för fortsatt skrivande? Föreliggande magisteruppsats beskriver Edith Södergrans, Karin Boyes, Elsa Graves, Sonja Åkessons och Katarina Frostensons debutverk. Dessa poeter analyseras i förhållande till senare verk. Metoden är textcentrerad och komparativ. Syftet med uppsatsen är att genom en jämförelse mellan debut
This thesis analyses the question of the right to compensation for victims of racial discrimination. The purpose is first of all to determine whether or not victims of racial discrimination have a right to compensation under international human rights law and to establish the content and limits of such a right. In order to achieve this purpose four specific questions are examined, namely: 1. Is th
Companies share their intellectual property with potential competitors in many different ways, including patent pooling. A patent pool is an agreement between two or more patent owners to license one or more of their patents to one another or to third parties. In Europe the Commission used the term patent pool as the bringing together of the patents of two companies, which makes it available for u
