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
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
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
In the Full-Scale Optimization approach the complete empirical financial return probability distribution is considered; and the utility maximizing solution is found through numerical optimization. Using a portfolio choice setting of three UK equity indices we identify several utility functions featuring loss aversion and prospect theory; under which Full-Scale Optimization is a substantially bette
The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. Photosynthetic oxygenation overcomes these limita

Belief revision theory and philosophy of science both aspire to shed light on the dynamics of knowledge – on how our view of the world changes (typically) in the light of new evidence. Yet these two areas of research have long seemed strangely detached from each other, as witnessed by the small number of cross-references and researchers working in both domains. One may speculate as to what has bro
This paper challenges the assumption that legal sociology should apply itself to the external or factual properties of the law and leave the internal and normative aspects of legal phenomena to doctrinal scholars and moral philosophers. It argues that legal sociology explores the normative contexts of the law and other social systems, but being restricted by its “scientific” mode of expression it
The MAX IV facility presently under construction will include two storage rings for the production of synchrotron radiation. The 3 GeV ring will house insertion devices for the production of x-rays while the 1.5 GeV ring will serve UV and IR users. Both rings will be operated at a constant 500 mA of stored current with top-up shots supplied by the 3.5 GeV MAX IV linac acting as a full-energy injec
This paper empirically examines the foreign internalisation decision of multinational corporations. The purpose of the paper is to identify determinants of the firm boundary, where within-boundary production takes the form of foreign direct investments (FDI) and outside-boundary production takes place through international outsourcing, with reference to recently developed general-equilibrium trade
Background: Psychotic illness can have a substantial economic burden not only on the patient and society in general, but also on family members providing informal care (i.e. those not subject to a market wage). While informal caregiving confers benefits for the patient and society, time spent providing informal care is diverted from other activities such as work or leisure. Relatives and caregiver
Full-scale experiments have been carried out to adapt the activated sludge model ASM2d to include the influence of metal dosage (Fe3+ and Al3+) for phosphorus removal. Phosphorus removal rates, nitrification rates, as well as pH and sludge settling performance, were evaluated as functions of the metal dosages. Furthermore, models relating certain parameters to the dosage of chemicals have been der
We derive explicit semiclassical quantisation conditions for the Dirac and Pauli equations. We show that the spin degree of freedom yields a contribution which is of the same order of magnitude as the Maslov correction in Einstein-Brillouin-Keller quantisation. In order to obtain this result a generalisation of the notion of integrability for a certain skew product flow of classical translational
