Left-hand drive (LHD) vehicles share higher road accident risks under left-hand traffic because of blind spot areas. Due to low import prices, the number of wrong-hand drive vehicles skyrockets in emerging countries like Georgia, Kyrgyzstan and Russia. I identify the causal effect of wrong-hand drive vehicles on road safety employing a new “backward version” of the synthetic control method. Sweden switched from left-hand to right-hand traffic in 1967. Before 1967, however, almost all Swedish vehicles were LHD for reasons of international trade and Swedish customer demand. I match on accident figures in the period after 1967, when both Sweden and other European countries drove on the right and used LHD vehicles. Results show that right-hand traffic decreased road fatality, injury and accident risk in Sweden by approximately 30 percent. An earlier switch would have saved more than 4,000 lives between 1953 and 1966.

States merge local governments to achieve economies of scale. Little is known to which extent mergers of county-sized local governments reduce expenditures, and influence political outcomes. I use the synthetic control method to identify the effect of mergers of large local governments in Germany (districts) on public expenditures. In 2008, the German state of Saxony reduced the number of districts from 22 to 10. Average district population increased substantially from 113,000 to 290,000 inhabitants. I construct a synthetic counterfactual from states that did not merge districts for years. The results do neither show reductions in total expenditures, nor in expenditures for administration, education, and social care. There seems to be no scale effects in jurisdictions of more than 100,000 inhabitants. By contrast, I find evidence that mergers decreased the number of candidates and voter turnout in district elections while vote shares for populist right-wing parties increased.

This master thesis analyses the impact of the euro on the German economy. The research is conducted through the examination of German export, GDP level, and labor market. It is also supplemented with the evaluation of the past, current and future stages of the Eurozone. The thesis provides a detailed theoretical background, which explains the motivation for the creation of a common currency. As a tool to prove the validity of my hypotheses I use the synthetic control method, where I model a hypothetical case, in which Germany did not adopt the euro. The validity of my results will be tested by using the confidence intervals and comparing the RMSPE ratio. By using this unique approach, I aim to contribute to the series of academic papers about the validity of the euro. In my research I have come to the conclusion, that the euro has positively influenced Germany's economy.

Recently the topic of the future of Ukrainian economy has been attracting great attention among economists and politicians. The way how it should develop is widely discussed on the international arena. Economists and politicians cannot reach an agreement to which direction it is better to move for Ukraine. Nowadays a lot of special institutions have been created on both sides: in Ukraine and in Europe. The main goal of those is to control all the processes of transformation to be transparent on all levels; as well as prevent unlikely events. Of course, there are proponents and opponents of the moving to the free trade with the EU as for every global process. Among the young generation it is very clear, that possibilities, which gives us European Union are much more valuable and gainful. Even now, majority of students and researchers seek to apply or acquire some knowledge in European countries. I'm not an exception and for this reason, being a representative of young generation, I will try to determine potential impact on Economy of Ukraine assuming integration to European Union. It is very important to consider both threats and benefits of such processes as they are taking place on very high level. Therefore, in this work it will be considered both contours of development for Economy of Ukraine....

This article describes that we grew InGaN ternary films by Plasma- Assisted Molecular Beam Epitaxy (PAMBE) on the ZnO substrate O-polar (0001) surface. Before we grew the films, we grew the InN films on the ZnO substrate to find out the interface reaction conditions. We used Double Crystal X-ray Diffraction (XRD) to analyze the diffraction peak of InGaN films after we grew them. We found it was very hard to grow the single content InGaN films by generally methods. We tried period shutter control method to grow films, and we succeeded to grow the single phase films. We analyzed the morphologies by AFM and SEM, the microstructures by TEM, the electric properties by Hall measurement, and the fluorescent characteristics by PL.

Extremely large telescopes (ELTs) are the next generation of ground-based reflecting telescopes of optical wavelengths. ELTs possess an aperture of more than 20 meters and share a number of common features, particularly the use of a segmented primary mirror and the use of adaptive optics systems. In 2005, the European Southern Observatory introduced a new giant telescope concept, named the European Extremely Large Telescope (E-ELT), which is scheduled for operation in 2018. The E-ELT will address key scientific challenges and will aim for a number of notable firsts, including discovering Earth-like planets around other stars in the ``habitable zones'' where life could exist, attempting to uncover the relationship between black holes and galaxies, measuring the properties of the first stars and galaxies, and probing the nature of dark matter and dark energy. In 2009, a feasibility study, conducted by National Instruments, proved the feasibility of the real-time (RT) control system architecture for the E-ELT's nearly 1,000 mirror segments with 3,000 actuators and 6,000 sensors. The goal of the RT control system was to maintain a perfectly aligned field of mirrors at all times with a loop-time of 1 ms. The study assumed a prescribed controller algorithm. This research report prescribes the optimal controller algorithms for large segmented telescopes. In this respect, optimal controller designs for the primary mirror of the E-ELT, where optimality is formulated in the [H-2] and [H-infinity] frameworks are derived. Moreover, the designed controllers are simulated to show that the desired performance metrics are met. / text

An overall process of globalization influences major changes in companies’ bussiness strategy. Supply chain management (SCM) becomes one of the most prioritetical activities in company. Seeking to survive in hard competition, they must improve their distribution strategies. Spreading Net technology requires flexible company to work directly with suppliers and to be able to react quickly and reasonably to demanding environmental changes. The classic objective of SCM is to be able to have the right products in the right quantities (at the right place) at the right moment at minimal cost. This requires a close integration of effective control functions and SCM to assure correctness and maturity of sending and receiving information, complience with internal company rules and supply strategies. This paper analyses SCM information systems emphasising their principles, pecularities and weaknesses. A new control method of SCM is introduced — „SCM using complex control methods“. It adds content management principles to current SCM control methods. This paper describes system concept, system architecture and generic business process models. To prove effectiveness of this method software was designed, developed and implemented in one big trading company. Additionally quality research of implemented software was made and it showed the effectiveness of applying quality assurence in software implementation process.

People respond to incentives—people make decisions by comparing the costs and benefits of a particular action. When either the costs or benefits change, behavior also changes. My dissertation focuses on estimating the impact of two different behaviour-altering taxes on household consumption. In the first section, I conduct an empirical examination of a hypothetical "fat tax" on household food consumption in Canada. The simulation results suggest that when fat tax revenues are recycled as lump-sum transfers to households, this policy would be the most efficient and progressive scenario from both economic and health perspectives. In the second section, I examine the impact of British Columbia's (BC) recently implemented carbon tax on household energy use from an aggregate perspective. I find no significant impact of the BC carbon tax on residential natural gas consumption. The third section is a further investigation of the BC carbon tax on household natural gas consumption varied by their environmental ideology. The results suggest that the impact of the carbon tax is more effective for non-environmentally conscious households than for other households.
