Design of the hammer set
Král, Ondřej ; Haltof, Vladimír (referee) ; Škaroupka, David (advisor)
This bachelor’s thesis is focused on the design of a product family of hammers by the means of generative design. The core of this thesis is the creation of an algorithm which will generate hammers of unified visual style, but varying properties based on input parameters. It is necessary that these hammers are in shape, ergonomics and dimensions adequate to preferences of the target group of professional workers and that they are producible in series and from commonly used materials. The output is a set of three hammers with different mass and dimensional properties.
The Domestic value added of Czech exports, its increasing and the role of the state in this process
Král, Ondřej ; Hnát, Pavel (advisor) ; Neumann, Pavel (referee)
This thesis deals with the topic of The Domestic value added of Czech exports, its increasing and the role of the state in this process. The main focus is on the low domestic value added of the crucial Czech export industries that represent the core of the Czech economy. We examine the data based on TiVA methodology which is the joint OECD-WTO initiative coping with changing global trade relations. It captures not only the domestic value added but also the origin of the foreign value added embedded in domestic exports. In this context, we critically examine the low level of territorial diversification of Czech exports and outdated policies in these areas. According to the outcomes of the analysis, the Czech economy is pursuing the path from the status of a transition economy that follows foreign markets to an innovation-driven economy that shapes industries, creates new ones and specializes on activities with high value added in GVCs. The Czech Republic can become one of these innovative economies only if it reviews its comparative advantages and adopts sound policies.
Phillips curve verification by time series analysis of Czech republic and Germany
Král, Ondřej ; Arltová, Markéta (advisor) ; Blatná, Dagmar (referee)
Government fiscal and monetary policy has long been based on the theory that was neither proven nor refuted since its origination. The original form of the Phillips curve has undergone significant modifications but its relevance remains questionable. This thesis examines the correlation between inflation and unemployment observed in the Czech Republic and Germany over the last twenty years. The validity of the theory is tested by advanced methods of time series analysis in the R environment. All the variables are gradually tested which results in the assessment of the correlation between the time series. The outcome of the testing is presented for both countries and a comparison at international level is drawn. Is is discovered that both of the countries have dependencies in their data. Czech republic has significant dependency in both ways, for Germany is the dependency significantly weaker and only in one way.
Interval linear systems with linear dependencies
Král, Ondřej ; Hladík, Milan (advisor) ; Rada, Miroslav (referee)
The main problem discussed in this thesis is about finding an enclo- sure of the solution set of an interval linear system with linear dependencies. We get familiar with definitions from interval arithmetic and analysis. Then we extend them to matrices and linear systems, where we introduce several modern approaches to finding an enclosure and divide them thematically. Most of them are implemented in MATLAB using INTLAB library. We compare their precision and computational time on Toeplitz, symmetric and random matrices. For depen- dencies we design our memory saving representation. The results are interpreted and the final function, which can compute either fast, sharp or memory efficient, is build on individual methods. Powered by TCPDF (

Power analysis
Král, Ondřej ; Malá, Ivana (advisor) ; Bílková, Diana (referee)
This thesis examines the issues of analysis of statistical power of a test. It introduces a subject of hypotheses testing which is closely related. The goal is to expose the effect of parameters' alteration on the power test size. By using an application on examples, the thesis graphically illustrates the differences caused by the parameters' alteration. The results show how is the power of a test influenced by the effect of type one error, type two error, the number of observations, the formulation of alternative hypothesis and effect size on test power. The thesis further elaborates on effect size forms. In conclusion, all the explained theories are tested by an example that illustrates the size, which is achieved by changing the parameter.
