Automatic Creation of PLC Program using TIA Portal Openness
Janeček, Pavel ; Kaczmarczyk, Václav (referee) ; Arm, Jakub (advisor)
This bachelor's thesis deals with automatic generation of PLC program with visualization for model 'Kuličky' through TIA Portal Openness. For this purpose a desktop application "TIAOpennessGenerator", by using programming language C#, was developed. This application generates PLC program according to suitably designed XML schema which works as a "recipe". Both schema and application are written in order to make data generating as universal as possible.

The Application for the PLC Program Generation using TIA Openness
Janeček, Pavel ; Pásek, Jan (referee) ; Arm, Jakub (advisor)
This thesis focuses on creating an application that allows generation of PLC and HMI programs using TIA Openness. The application is programmed to separate logic from graphics, which is beneficial in case of a change of the visuals of the application. Generating programs is possible thanks to the XML transcription or by creating a configuration within the application guide. The generating is done by overwriting source XML files contained in the application library according to the selected configuration. The application was created with Framework Windows Forms in C#. A reference set of device modules has been created for PLC and HMI in the development environment of TIA Portal V15.1. The source XML files, on the basis of which the generating is carried out, were then obtained by exporting a reference set and placed into the application library. With a simulation tool Factory I/O and S-7 PLCSIM it was verified that the generated program is, thanks to the mapping of variables on pins of blocks, fully functional in manual mode. At the same time it was proved that it is possible to generate programs for different devices which signifies the versatile use of this application. The contribution of this work is the significant reduction of time when creating new PLC and HMI programs.

The influence of surface modification of glass fibers on mechanical response of the GF/polyester composite
Janeček, Pavel ; Richtera, Lukáš (referee) ; Čech, Vladimír (advisor)
The diploma thesis is aimed at an influence of surface modifications of fibrous reinforcements on mechanical properties at the fiber-matrix interface in fiber reinforced composites. Glass fibers were used as reinforcements and polyester resin was the matrix. The sample of composite consisted of polymer matrix in a form of cylindrical body placed on bundle of glass fibers. The design of the sample was constructed with respect to results of Finite Element Analysis (FEA). The tensile test using a materials testing machine (Zwick) was employed to evaluate adhesion at the fiber-matrix interface. Untreated glass fibers, fibers with commercial sizing, and fibers modified by deposition of plasma polymer film using Plasma-Enhanced Chemical Vapor Deposition (PECVD) at different deposition conditions were used for fabrication of composite samples. The fibers and composite samples were analyzed by Scanning Electron Microscopy (SEM) and Confocal Laser Scanning Microscopy (CLSM).

Influence of POWERBREATHE on changes in respiratory parameters by swimmers
Janeček, Pavel ; Kovářová, Lenka (advisor) ; Chrzanowská, Babeta (referee)
Title: Influence of POWERBREATHE on changes in respiratory parameters by swimmers Objectives: The goal of bachelor thesis is what influence has Powerbreathe on changes in respiratory in swimmers. It will be also determined if a group of better- performing swimmers will achieve statistically better results from Powerbreathe. Last goal will be find out if training with Powerbreathe by instructions influence statistically improvement measure results. Method: Data were collected before start of research and after from Powerbreathe. Results are processed to charts and evaluate into software SPSS in statistics method pair T-test and non-paired T-test for two files. Results: In the analysis, we concluded that there are no statistically significant differences between the TOP swimmers and the REPRE swimmers when we were comparing the results of the values measured on the Powerbreathe. Furthermore, we did not find statistically significant differences when we were comparing the results of the values measured before and after the test. The results did not change even if we split the group into a group of performance better TOP swimmers and performance worse REPRE swimmers. Key words: Powerbreathe, breathing, swimming, performance

Czechoslovak-Korean relations during the Korean War 1950-1953
Janeček, Pavel ; Nálevka, Vladimír (advisor) ; Tůma, Oldřich (referee)
The relations between Czechoslovakia and North Korea started in October 1948. The Czechoslovak Republic as one of the first countries in the world acknowledged Kim 11-sung's state. In the following two years, no progress was made in Czechoslovak-North Korean relations. The Czechoslovak legation was founded in September 1950, the first North Korean envoy arrived in July 1951. The relationship was very friendly in years 1950-53. In fact, it was rather an alliance. After the beginning of the Korean War, Czechoslovakia protested against measures taken by the Security Council. Czechoslovak communist leaders considered the intervention against North Korean aggression illegal. During summer 1950, many resolutions against "American imperialism" were sent to the United Nations from Czechoslovakia. Economic aid to North Korea also started in the summer of 1950. Until the end of the war in Korea, goods worth 800 million crowns were sent from Czechoslovakia. As another means of help to North Korea, Czechoslovakia took care of nine hundred Korean children and provided education for 170 high school students and 150 university students. The Czechoslovak Republic also sent a military hospital with two hospital teams consisting of 58 people to Korea in 1952. The total value of Czechoslovak aid was about 1 000 millions...
