Systems of Parallel Grammars
Skácel, Jiří ; Horáček, Petr (referee) ; Meduna, Alexandr (advisor)
This article defines cooperating distributed grammar systems with E0L components instead of context-free grammars and discusses its generative power mainly in respect to ET0L systems. It recapitulates results about CD GS, then defines modified systems and shows that this combination has in most derivative modes equal strength to ET0L, except for terminating mode, which is shown to be more powerful. There are also explained examples of this new kind of systems.

System for the Data Presentation and Data Collection
Skácel, Jan ; Burget, Radek (referee) ; Milička, Martin (advisor)
The aim of this bachelor's thesis is to design and implement a tool that allows receiving data from multiple agents and representation of those data to logged in users. Model of recorded data is created by designer using special tool integrated into developed aplication. The application backend is implemented in Python language using Model-view-controller design pattern. Used database management system is MySQL. For definition of views within the application is used application specific scripting programming language.

Human Detection Using Radar
Skácel, Jan ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
This work is focused on the design and implementation of algorithm for human detection in real time using a continuous wave radar. Classification of people is based on doppler signatures produced when they walk. Fourier transform techniques were used to analyze these signatures and key features were identified that are very representative of the human walking motion. On the basis of design, the C++ application that process radar signal and detects human is implemented. Last part of this work is focused on algorithm evaluation.

Business Process Mining
Skácel, Jan ; Kreslíková, Jitka (referee) ; Bartík, Vladimír (advisor)
This thesis explains business process mining and it's principles. A substantial part is devoted to the problems of process discovery. Further, based on the analysis of specific manufacturing process are proposed three methods that are trying to identify shortcomings in the process. First discovers the manufacturing process and renders it into a graph. The second method uses simulator of production history to obtain products that may caused delays in the process. Acquired data are used to mine frequent itemsets. The third method tries to predict processing time on the selected workplace using asociation rules. Last two mentioned methods employ an algorithm Frequent Pattern Growth. The knowledge obtained from this thesis improve efficiency of the manufacturing process and enables better production planning.

Supply, Demand, Interaction of Advertising
Skácel, Jiří ; Karabec, Jiří (referee) ; Vykopalová, Hana (advisor)
his thesis deals with the supply and demand and the impact of advertising on these two microeconomic variables. The work is focused on describing the operation of supply and demand from marketing point of view and not from a microeconomic perspective. In the theoretical part of this work to explain the essence of marketing and advertising, that can well influence the need and demand for goods and services. I'm also concerned with marketing mix and communication mix, which is the theoretical basis for the establishment of marketing activities to promote services and products. The theoretical outline the development of communication campaigns, as each campaign must be properly planned so as to be successful. The aim of this thesis is to examine the functioning of supply and demand, and assess the impact of advertising on supply and demand. This issue in a practical example of the real estate agents Dachi,Ltd., based in Olomouc. Practically make a quantitative marketing research methods and hypotheses are tested using a test of goodness of fit chi-square.

Purchase process standardization
Skácel, Jakub ; Kotek, Luboš (referee) ; Kotek, Luboš (referee) ; Fiala, Alois (advisor)
This master's thesis is engaged in standardization of relation between costumer and supplier from perspective of purchasing products in the automotive industry. In this thesis are specified requirements at the suppliers of plastic parts. The costumer is Robert Bosch České Budějovice (RBCB). By standardization we understand selection and description of customer’s requirements at supplier.

Study of BGA and QFN package properties
Skácel, Josef ; Psota, Boleslav (referee) ; Szendiuch, Ivan (advisor)
This work deals with the issue of packaging and heat transfer. Especially this work focused on QFN and BGA packages. Nowadays most sophisticated conventional solution. First part deals with analysis of the current status of packages. Next part is analyze the issue of heat transfer in electronic systems. The following section is an experimental dealing with simulation in ANSYS Workbench and validation of these simulations by designed test structures. At the end is evaluated properties and behavior of these packages.

Thermomechanical simulation of modern electronic packages
Skácel, J.
This paper deals with issue of modern electronic packages mainly thermo-mechanical simulation. The first part is focused on the comparing of QFN (Quad-Flat No leads) and BGA (Ball Grid Array) packages including their advantages and disadvantages. The second part is focused on simulation of these packages in ANSYS program from the point of thermos-mechanical behavior.
