Belt conveyor
Konečný, Tomáš ; Pokorný, Přemysl (referee) ; Řezníček, Milan (advisor)
The aim of this bachelor's thesis is to propose design solutions conveyor belt to transport sand and gravel to concrete batch mixer. The maximum transport capacity 2000 kg/cycle, the cycle time benefits, including stirring for 4 min and 4.5 m height difference work contains a description of the main functional parts of the conveyor belt, functional calculations according to standard ISO 5048, determination of main dimensions, the design of the drive and tensioning devices. Strength calculation is performed for tightening screws, nuts and truss structures.

Unconventional Design of Internal Combustion Engines
Konečný, Tomáš ; Drápal, Lubomír (referee) ; Svída, David (advisor)
The content of bachelor thesis is to explore the possibility of replacing the traditional arrangement of crankshaft and timing mechanism in combustion engines. The aim of this work is to design the default parameters for the selected engine performance. After designing the default parameters are designed and created CAD models of basic engine components. Subsequently developed a basic overview of alternative concepts of internal combustion engines and elaborated a basic available analysis of the structure. In the conclusion of the thesis is evaluation of the results.

In the Quest of Measuring the Financial Cycle
Plašil, Miroslav ; Konečný, Tomáš ; Seidler, Jakub ; Hlaváč, Petr
The recent financial crisis has demonstrated the importance of the linkages between the financial sector and the real economy. This paper sets out to develop two complementary methods for assessing the position of the economy in the financial cycle in order to identify emerging imbalances in timely manner. First, we construct a composite indicator using variables representing risk perceptions in the financial sector and calibrate this indicator to capture the credit losses the Czech banking sector experienced during the recent crisis. Second, we focus on the transitions of loans from one risk category to another, which allows us to capture the financial cycle from the perspective of the debt-paying ability of non-financial corporations. Both financial cycle measures can be used by policy makers for a wide range of policy decisions, including that on the setting of the countercyclical capital buffer.

Macroeconomic Factors as Drivers of LGD Prediction: Empirical Evidence from the Czech Republic
Belyaev, Konstantin ; Belyaeva, Aelita ; Konečný, Tomáš ; Seidler, Jakub ; Vojtek, Martin
This paper focuses on key macroeconomic driving factors influencing the loss given default (LGD) – an important credit risk parameter determining credit losses of the banking sector. Various econometric approaches are applied on both individual and aggregated data for different bank segments in order to identify the sensitivity of LGD parameters to both the micro characteristics of debtors and aggregated macro-level data. Despite the relatively low importance of macro variables in the model combining micro- and macroeconomic information, our estimates suggest that the macroeconomic environment contributes directly to the variation in LGD. The results from the different approaches confirm a negative link between LGD and consumption growth for the retail portfolio, while in the case of the corporate segment, a negative link between LGD and real GDP growth is identified. Importantly, given that aggregation effects and non-linearities may substantially affect the choice of relevant macroeconomic variables, it is essential to distinguish between models employing purely macroeconomic data and models combining micro- and macro-based information.

Evaluating the Links Between the Financial and Real Sectors in a Small Open Economy: The Case of the Czech Republic
Konečný, Tomáš ; Babecká Kucharčuková, Oxana
In this paper we use a battery of various mixed-frequency data models to forecast Czech GDP. The models employed are mixed-frequency vector autoregressions, mixed-data sampling models, and the dynamic factor model. Using a dataset of historical vintages of unrevised macroeconomic and financial data, we evaluate the performance of these models over the 2005–2012 period and compare them with the Czech National Bank’s macroeconomic forecasts. The results suggest that for shorter forecasting horizons the accuracy of the dynamic factor model is comparable to the CNB forecasts. At longer horizons, mixed-frequency vector autoregressions are able to perform similarly or slightly better than the CNB forecasts. Furthermore, moving away from point forecasts, we also explore the potential of density forecasts from Bayesian mixed-frequency vector autoregressions.

Transformation process in Slovakia - strong and weak sites
Kavčák, Adam ; Klosová, Anna (advisor) ; Konečný, Tomáš (referee)
The work will examine the fundamental transformation process of economic development in Slovakia. It seeks to define the initial stage of the Slovak economy, depending on the political power of the state. Interconnection policy and the economy has significantly affected the direction of the country and therefore the objective of this work is to characterize the development of purely economic, but rather in terms of political and economic. The work deals with the liberalization, privatization and structure of international trade.
