In this thesis, the focus is on the trade relations between Estonia and selected Asian countries based on their importance, aiming to identify the current trade flows, changes within them over time and the reasons behind these changes. Furthermore, the comparative advantage of Estonia in relation to those countries should be revealed. The main research question is how the trade flows have changed
Anknytningens påverkan på implicita emotionella åsikter gentemot vårdnadsgivare studerades genom ett experiment som innehöll en affektiv priming uppgift liknande den välkända lexikala beslutsuppgiften ”lexical decision task” (LDT). Reaktionstiden i millisekunder för varje prime och mål ord kombination registrerades och användes som indikator för den associativa styrkan mellan de två. Två anknytnin
The quantum cascade laser (QCL) is a semiconductor heterostruc- ture using inter sub-band transitions to generate stimulated emission. The quantum cascade detector (QCD) is a similar to the QCL, but the heterostructure is tailored to absorb radiation and give a read-out current. In this work, three planned or realised QCL:s and two QCD:s have been simulated and analysed using a program based on th
Syftet med denna studie är att ta reda på hur elever reflekterar över sitt eget lärande inom rytmikämnet och hur detta generellt påverkar deras lärande. Målet är att genom tolkning och analys av elevernas svar kunna utveckla rytmikmetoden och därmed bidra med material till den vetenskapliga litteratur som idag finns inom detta område. Ett delmål är också att bidra till utveckling av metoder för reTitle: Eurhythmics, learning and reflektion. Student insights on the significance of reflection in their personal learning experiences. The purpose of this study is to find out how students reflect on their learning process in eurhythmics and how this in turn affects their overall learning. The interpretation and analysis of student responses will be used to further the development of eurhythmics
Carbonatite is an unusual type of rock that, for a long time, were not accepted for what they really are. This group of rocks is now considered to be of igneous origin and is classified after its content of carbonate minerals. If it exceed 50% the rock will be named a carbonatite. This group of rocks can be found all over the world and two of these places, which this review will focus on, are the
Model Predictive control (MPC) has been studied extensively because of its ability to handle constraints and its great properties in terms of stability and performance [Mayne et al., 2000]. We have in this thesis focused on MPC of Hybrid Systems, i.e. systems with both continuous and discrete dynamics. More specifically, we look at problems that can be cast as Mixed Integer Quadratic Programming (
Hirham5, a weather model developed at DMI, does not have a very good approximation for the snow albedo. To make the model better a snow albedo code, based on Dickenssen’s equation for snow albedo, was implemented in the model where the albedo depended on more variables than just the temperature. This change is important since the radiation contributes more to the melt than the temperature. The sur
Lately mergers and acquisitions made larger power distribution companies. The economic benefits of those are carefully calculated. But what’s much more complicated is to calculate all consequence of mergers. Very few things in business are certain. The precision of science doesn’t apply to business. Universal “laws of nature” do not govern business; no formula “replicates” good management. Decisio
Christopher Polhem (1661-1751), called the father of Swedish mechanics, is the most famous figure in Swedish history of technology and our nation's foremost inventor ever. Remarkably enough, a close survey in a monograph has never been written on this inventor who in many ways initiated the technical and industrial development of Sweden. In this project will Polhem for the first time get a broad a

Much of the progress in astronomy follows imaging with improved resolution. In observing stars, current capabilities are only marginal in beginning to image the disks of a few, although many stars will appear as surface objects for baselines of hundreds of meters. Since atmospheric turbulence makes ground-based phase interferometry challenging for such long baselines, kilometric space telescope cl
Hydrogen normally occurs as hydroxyl ions related to defects at specific crystallographic sites in the structures, and is normally characterized by infrared spectroscopy (FTIR). For quantification purposes the FTIR technique has proven to be less precise since calibrations against independent methods are needed. Hydrogen analysis by the NMP technique can solve many of the problems, due to the low
Since the early 1960s, water chemistry and phytoplankton have been monitored in several lakes in Sweden. However, as early as 1900-1901, the German algologist Lemmermann investigated phytoplankton from lakes in Scania, southern Sweden. Several phytoplankton samples from these investigations were preserved and saved, and are deposited at the Department of Ecology in the University of Lund. These ol
Many student–industry activities have emerged in recent years, and universities have invested considerable time and energy in designing and implementing such collaboration models. However, as models differ significantly, student–industry activities should not all be bundled together. This paper examines student–industry activities conducted as integral parts of engineering study programmes. These
Jet engine noise is an environmental problem that needs to be addressed. Several methods to reduce the jet noise have been proposed in the last decades. The main issue is to find methods that reduce noise without causing considerable loss of thrust. Experimental and computational tools are mandatory in successfully reducing jet engine noise emissions. One of the challenging issues of computing the
The construction sector provides the direct means to the development and expansion of economic activities, but is at the same time a major consumer of physical and natural resources and a polluter of the environment. Over the last decades, the environmental impact of construction activities has grown dramatically due to the increase in the world population and greater industrial and human activity
Gel dosimetry measures the absorbed radiation dose with high spatial resolution in 3D. However, recently published data show that the response of metacrylic-based polymer gels depends on the segmented delivery pattern, which could potentially be a considerable disadvantage for measurements of modern dynamic radiotherapy techniques. The aim of this study is to design a dynamic compartment model for
The release of the hydrophobic cancer drug dasatinib from two mesoporous silica materials as drug delivery vehicles has been studied. One material is a reference 2D-hexagonal SBA-15 with the typical bimodal pore system with ordered primary mesopores and disordered intrawatI pores. The other material is a modified version of the same material where the intrawall porosity in the micropore regime has
