Minimisation of Logical Functions
Horký, Miroslav ; Davidová, Olga (referee) ; Šeda, Miloš (advisor)
For minimisation of logical functions, laws of the Boolean algebra and the Karnaugh maps are mostly used. However, use of Karnaugh's maps is based on visual recognition of adjacent cells for functions with no more than 6 variables and, therefore, the method is not suitable for automated processing on computers. A direct application of the Boolean algebra laws is not restricted in this way, but there is no general algorithm defining the sequence of their application and thus this approach is not suitable for computer implementation either. The well-known method usable on computers is the algorithm proposed by E. J. McCluskey and W. Orman Quine.

Sample tasks for automation education
Sileská, Silvia ; Janečka, Jan (referee) ; Davidová, Olga (advisor)
This bachelor´s thesis deals with the design and demonstration of tasks addressing combinatorial and sequential logic circuits. To resolve the assignment must be familiar with the theory of logical management, with program LOGO!Soft Comfort and issue of programmable controllers. Overall, the proposed six tasks are solved by basic rules for use in a logical management. Finally, it was necessary to verify the proper functioning of the proposed tasks, which it realized by using LOGO!Soft Comfort and programmable logic computers. The proposed tasks will serve as a demonstration tool for teaching the subject of automation.

Controllers design for plants with small time constants
Rozmahel, Ivan ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
The main reason of this project is to set up and to propose continous controllers for process with small time responses. The regulated circuits with different type of regulators and its different settings were proposed in this project. These parameters were set up with method synthesis. These calculation were compared and evaculated as regards to control accurancy and quality.

Catalog of standard logarithmic frequency characteristics
Velecký, Pavel ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
One of the options how to suggest the parameters of the continuous action controller is to use a method of standardized logarithmic amplitude frequency characteristic. It is a frequency method based on the choice of the form of standardized logarithmic amplitude frequency characteristic of open control circuit. I have created a catalogue of standardized logarithmic frequency characteristics in order to facilitate the work while using this method.

Controllers design for plants with dead time
Matyáš, Miroslav ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
This bachelor's thesis covers the subject of a design of controllers for regulated systems with time delays. The theoretical part of the thesis describes suitable methods for the determination of parameters of continuous-action and digital controllers for those systems. Specifically, they are the Desired model method, the Multiple dominant pole method, the "Universal" experimental method, and the SIMC (SIMple Control) method. In the practical part of the thesis, the methods are applied to the controller parameters’ design, and regulation courses are modelled in MATLAB/Simulink software. At the bachelor thesis conclusion, the regulation is evaluated with regard to its accuracy and quality.

Simple and branched control circuits
Holoubek, Lukáš ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
The goal of this thesis is a theoretical and practical comparison of simple and branched controlled circuits in relation to regulation ‘s quality. Theoretical part describes control, regulation, regulation ‘s circuit, regulator and its parameters setting. There are specific transmissions of the regulated system set on which a step signal response and a fault’s signal pulses are simulated on. Regulation’s quality results are closely analyzed and described using Matlab/Simulink program.

Globalization and Health - access to health care for children of foreigners in the Czech Republic
Davidová, Olga ; Háva, Petr (advisor) ; Mašková, Pavla (referee)
Olga Davidová - Abstrakt DP - AJ Abstract Diploma thesis "Globalization and Health - access to health care for children of foreigners in the Czech Republic" addresses the issue of availability of health care for children of foreigners in the Czech Republic as development of legal framework in the Czech Republic and human rights issues. The main objective of this work is a critical reflection on the cause of discrimination against children of foreigners from third world countries (non-EU countries) in their access to health care. This is a retrospective case study which is selected by the institutional analysis of the key events of public policy focusing on the development of health insurance legislation. There are different mechanisms of protection of human rights at local, national, and international level in the availability of health care for children of foreign nationals from third world countries; unfortunately national legislation is not fully in line with international requirements in the area of health law. Although international documents are binding for the Czech Republic, they are not sufficiently applied in the Czech constitutional right to prevent violations of human rights.
