Design of inspection procedure for selected revolver components
Úlehlová, Eva ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The goal of this master’s thesis was design of the inspection procedure for hammer and trigger of the specific revolver model. Thesis was developed in cooperation with the manufacturer of the revolvers. The theoretical part deals with the MSA methodology, which is used to assess acceptability of measurement systems. The practical part describes the current measurement system and performs gage repeatability and reproducibility study. It was confirmed that the current measurement system requires improvement. Subsequently coordinate systems were designed, based on functional features of the hammer and trigger. Automated optical measurements, based on the coordinate systems, were performed. The results from these measurements were again assessed by the gage R&R study. The analysis confirmed improvement of acceptability of the designed measurement systems. Based on these results, it is recommended to apply suggested procedures in practice. Results and recommendations of this master’s thesis can contribute to develop metrology in the company and improve the existing measurement system.

Suggestions for changes in the production of a part "revolver trigger"
Jiráček, Jan ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The study deals with production technology of “revolver trigger“. Final assembly is short firearm ALFA Steel and its model series of ALFA-PROJ, Ltd company. Introduction submits an explanation of trigger technology suitability. The following analysis describes current manufacturing process, which has manufacturing inaccuracy problem. Furthermore rootcause of manufacturing inaccuracy was determined and analysis of suggestions for changes (including modifications of technological process) was realized. Based on experiment dimensions were measured on provided samples of suggest production in Technical Control Department. Dimensions of triggers manufactured by current production were verified during the experiment too. Results were compared according to the rejects of production. In the final phase of the study manufacturing labor costs were compared for the one piece of trigger with the new suggested technology.

MySQL and MS SQL Database Synchronization
Šimanovský, Filip ; Grégr, Matěj (referee) ; Trchalík, Roman (advisor)
This thesis describes the synchronization of MySQL and MS SQL databases . It explores and describes differences between these two database servers and further designs and implements alghorithms for their safety and economicaly favourable synchronization . Designed methods are implemented in a console application afterwards . Two case studies are used as an illustrative of its work . The result of this thesis is a manual on how to successfully convert MySQL database to MS SQL database (and vice versa ) and the convert application itself .

Universal Measurement Station
Šantavý, Marek ; Bartoš, Pavel (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to create data acquisition application. The software module is designed for the industrial panel PC. Power Panel 520 from Bernecker + Reiner and the data acquisition board NI USB-6215 from National Instruments represent the fundamental hardware components for this project. Data acquisition and visualization tasks are controlled by a standalone application made in LabVIEW 2011. OPC, industrial standard in communication, is responsible for mutual interconnection between control (PLC) and data acquisition part. Network shared variables and Apple iPad 2 allow remote surveillance for operator. Finally, the creation of user-friendly interface and integration of technologies from different vendors, are main goals of this project.

Technology in production of handguns
Medůsek, Milan ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The thesis discusses the possibility of a rationalizing of a production of handguns in the conditions of the Česká zbrojovka, a.s. company. In the beginning of the theoretical part, it deals with a familiarization with CZUB, its subsidiaries and a manufacturing portfolio. The following is a division of weapons, a describe of components of firearms and their method of a production. The practical part focuses on the possible rationalization of a production of components of a trigger, a hammer and a magazine catch. After analyzing the current situation in the company, the individual variants of the new technologies are described theoretically first of all. The technological processes for each component at each considered technology are created for these new variants. The following is the calculation of the required values for the final comparison. The final part is the technical-economic evaluation, which compares various technological options among themselves. In the final discussion, the possibility of the individual technologies and their implementation risks in the production process are mentioned.

Signal and data logger
Borsányi, Tamás ; Vyskočil, Pavel (referee) ; Kolouch, Jaromír (advisor)
The goal of this project is to design a signal and data logger, which captures analog and digital signals with very long record time. The device supports multichannel complex triggering, a real-time oscilloscope-like mode and an offline mode for analyzing of previously sampled data. This project contains detailed analysis of the topic, description of hardware and software solutions and used methods. The thesis also contains verification tests and measurements. This device will be mainly used for hardware debugging of microprocessor based applications.

Designing a database and an application as a parametric web page for hotel owners
Menzel, Aleš ; Palovská, Helena (advisor) ; Chudán, David (referee)
This thesis consists of analysing database requirements, designing and creating a database for the needs of a reservation system and its corresponding parts. The purpose of this thesis is the practical implementation of the database and subsequently creating an application in the form of an administration interface, which is implemented in MySQL database platform and web technologies. Objective of the application is to provide complex system, which connects the parametric administration system with web pages in such a way, that the administrator of the application can manage the application from within the administration section. Requirements for this application and database are based on analysing the competitor's products and my own experience with creating a web application for a small pension. The goal is achieved by designing a flawless database and implementing the application. Furthermore the application proves and validates the database implementation by using test data. Main contribution of the thesis is completed application based on a high quality database model that is ready for deployment in practice. Structure of the thesis consists of two parts. First part describes theoretical basics that are important to know before designing a database and a short introduction to history of database models. The second part is dedicated to designing the database itself.
