This diploma thesis deals with the issue of evaluation of economic development in Visegrad group countries compared to Germany in years from 2009 to 2015. The aim of the thesis is to take down and to evaluate economic development in this period based on the analysis of macroeconomic indicators. In the theoretical part, there are several notions explained, such as the definition of GDP, economic growth rate, unemployment rate, balance of payments or economic cycle. In the practical part, there is an analysis carried out which describes the concrete data development of macroeconomic indicators in Visegrad group countries in comparison to Germany. Subsequently, general characteristics of the countries are deduced. At the end of the thesis, the findings are summarized, and further possibilities of elaboration are foreshadowed.

The general purpose of this study is to determine the contribution of agriculture to the economy of Ghana. The country’s economy is characterised by the presence of high level of agriculture. Agriculture is the main economic activity for most people in Ghana. The study reveals that agriculture contributes about 18% to GDP, 40.65% of total employment, and about 34% of total exports of agricultural valued added goods and source of industrial inputs (raw materials) in the country. Nevertheless, agriculture in the country has faced the following challenges: low fertiliser uses and yield, pests and diseases, inadequate modern farm inputs and technologies, lack of financial support systems, rural-urban migration, agricultural extension services, land tenure system, poor road network, and low prices for agricultural products. The government should encourage more exportation of agricultural output this would concurrently, augment the country’s foreign exchange record in a positive direction and bolster the competitive qualities of the country’s products on the international front. Also, agricultural universities, if none exist, must be created and equipped with financial and technological capacities to carry out serious research and investigation into all facets of the agricultural economy; including; forestry, aquaculture, apiculture, diseases and pest, and crop production, not excluding post-harvest and marketing researches.

This thesis aims to identify the links between economic developments and move-ments in US stock markets. The period from Q1 2001 to Q3 2016 inclusive was chosen for an analysis of the relationship between trends in GDP time series and the S&P 500 index. A correlation analysis was carried out on the time series ex-amined, while the Granger causality test was used to determine the causal rela-tionship between them.

The aim of this thesis is to verify the predictive ability of selected economic and financial leading indicators of future economic development in the Czech Republic. Economic development is expressed through GDP. The literary part deal with GDP and an alternative indicator of economic development. The literary section also presents a cross-section of empirical studies by various authors dedicated to leading indicators. The empirical part is focused on the relationship between GDP and leading indicators in terms of its existence, strength and direction. Correlation analysis is used to reveal the relationship and strength. Multi-dimensional time series analysis in the form of VAR models is used to reveal the direction, followed by Granger causality.

Big data is a concept that is expanding rapidly. As more and more data is generatedand garnered, there is an increasing need for efficient solutions that can be utilized to process all this data in attempts to gain value from it. The purpose of this thesis is to find an efficient way to quickly process a large number of relatively small files. More specifically, the purpose is to test two frameworks that can be used for processing big data. The frameworks that are tested against each other are Apache NiFi and Apache Storm. A method is devised in order to, firstly, construct a data flow and secondly, construct a method for testing the performance and scalability of the frameworks running this data flow. The results reveal that Apache Storm is faster than Apache NiFi, at the sort of task that was tested. As the number of nodes included in the tests went up, the performance did not always do the same. This indicates that adding more nodes to a big data processing pipeline, does not always result in a better performing setup and that, sometimes, other measures must be made to heighten the performance. / Big data är ett koncept som växer snabbt. När mer och mer data genereras och samlas in finns det ett ökande behov av effektiva lösningar som kan användas föratt behandla all denna data, i försök att utvinna värde från den. Syftet med detta examensarbete är att hitta ett effektivt sätt att snabbt behandla ett stort antal filer, av relativt liten storlek. Mer specifikt så är det för att testa två ramverk som kan användas vid big data-behandling. De två ramverken som testas mot varandra är Apache NiFi och Apache Storm. En metod beskrivs för att, för det första, konstruera ett dataflöde och, för det andra, konstruera en metod för att testa prestandan och skalbarheten av de ramverk som kör dataflödet. Resultaten avslöjar att Apache Storm är snabbare än NiFi, på den typen av test som gjordes. När antalet noder som var med i testerna ökades, så ökade inte alltid prestandan. Detta visar att en ökning av antalet noder, i en big data-behandlingskedja, inte alltid leder till bättre prestanda och att det ibland krävs andra åtgärder för att öka prestandan.

The aim of the thesis is to verify the interdependence of stock markets with the development of the national economies of the V4 countries and on basis of the established links, to assess possible forecasting of the future development of GDP and the development of V4 stock markets. Literary overview of the diploma thesis describes the economic development of the V4 countries with a focus on the eco-nomic indicator of GDP, the critism of the GDP indicator and its possible alternati-ves measuring the efficiency of the economy. In addition, there are described indi-vial stock exchanges of V4 countries, theory of efficient markets together with possible anomalies in the financial markets. The last part of the literky review contains previously Publisher studies dealing with the issue. The work itself is dividend into main parts, namely the correlation analysis and the compilation of VAR models according to which the direction of the relationship will be tested within Granger causality.

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.

Il s'agit de dépôt de silice utilisant le silane et l'oxygène dans un système plasma haute densité. L'influence des paramètres du procédé et du système d'injection du silane sur les propriétés des matériaux sont étudiés par ellipsométrie spectroscopique, spectroscopie infrarouge à transformée de Fourier, spectroscopie de transmission et microscopie à force atomique. On étudie la phase gazeuse par spectroscopie d'émission optique et spectrométrie de masse quadripolaire avec pompage différentiel. La création de l'eau dans le système et son incorporation dans les couches pendant le dépôt sont étudiées utilisant l'injection du silane par jet capillaire. L'absorption du Si-OH dans les couches est mesurée en différentes positions sur le substrat. Les simulations de flux de gaz par la technique simulation directe Monte-Carlo sont utilisées pour étudier le flux des espèces sur le porte substrat. On a trouvé que le flux de l'eau est uniforme tandis que le flux de silane varie sur le porte substrat, ce qui explique la faible quantité de silanol dans la couche dans les régions déposées à grande vitesse. Une comparaison entre les résultats expérimentaux et les simulations montre que les systèmes plasma haute densité peuvent seulement être considérés comme bien mélangés quand il n'y a pas une élimination rapide des espèces en phase gazeuse.
