A software interface for a laser tracker user application
Kozáček, Peter ; Kovář, Jiří (referee) ; Knobloch, Josef (advisor)
For assembly of product machine is necessary to evaluate a geometric accuracy of individual functional parts of the machine. This process is very demanding and time consuming. One of the reasons of mentioned problems is the lack of software (adaptation) for measuring of the accuracy of geometrical precision. This theses (diploma work) focuses at facilitating the development and creation of own application based on customer requirements and for measuring geometric accuracy with the Laser Tracker AT901 from Leica company. The aim is to create a basic application suitable for measurement of geometric accuracy, which would speed up this process, would be user-friendly, simple and open for further expansion.

Artificial Intelligence and Industry 4.0
Kotas, Filip ; Kroupa, Jiří (referee) ; Kovář, Jiří (advisor)
This bachelor thesis deals with search for artificial intelligence methods used in the diagnostics of technical systems. The first part of the work is devoted to the search of used methods in the field of diagnostics of technical systems. The second part summarizes the characteristics and applications of these methods. The conclusion of the thesis deals with the application of the artifical neural network method and the hybrid method „adaptive neuro-fuzzy inference systém“, which is based on the neural network. This part deals with a detailed description and use of these methods in real technical systems.

USB miltimeter with microprocessor
Samek, Martin ; Kolka, Zdeněk (referee) ; Kovář, Jan (advisor)
Topic of my terminal labour is a proposion of multimeter and its resulting connection by the help of bus USB. When proposing the multimeter there was a tendency to use a minimal number of component parts to conserve a good protection against a bad usage in application. The most widespread busbar USB is used for connection of the multimeter and a computer. Standard HID is used for communication, for that it is not neccessary to install any system drivers.

GSM communicator for the lift
Půhoný, Jan ; Krzák, Tomáš (referee) ; Kovář, Jan (advisor)
In this bachelor thesis a microcontroller is applied to a defined and practical construction of THE GSM COMMUNICATOR FOR LIFT. This unit is constructed as a small low-cost emergency speech system for lifts. There are two units – one for the cab box (speech) and the other one for the machine room (GSM connection to the dispatching centre). The connection between these units is realized only by a two-wire aerial cable. The communication to the dispatching centre is based on GSM Wavecom module to send the information about the lift status via SMS messages and audio signal for speech from the cab box.

Optimizing the operation of domestic wastewater treatment plants
Kovář, Jan ; Vachovec, Roman (referee) ; Hluštík, Petr (advisor)
The bachelor thesis deals the possibilities of optimizing the domestic wastewater treatment plant. The research part focuses on ways of discharging wastewater from small sources. The most frequently observed indicators, which are reported in the current legislation, are also mentioned in this part. The practical part focuses on a description optimized of an domestic wastewater treatment plant and it is resulting problems with the operation, as well as the individual outputs of samples and their comparison with indicators in the legislation. The last section provides optimization recommendations that address emerged issues.

Machine vision implementation for control of parallel mechanism
Zábrša, Tomáš ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
The topic of this bachelor thesis covers issues of parallel robotics. It is focused on challenges of one particular type of parallel robot – delta robot. In this thesis it is described history of parallel robotics, kinematical calculations and machine vision. In the last part of this thesis is description of practical programming of delta robot and palletisation task using machine vision. Parallel robots have, compared to serial robots, certain advantages, but also disadvantages. Parallel robots are more stable, lower mass and they have higher accelerations and can do more work cycles. Using machine vision they can be used for sorting tasks, for example to put product into crates or sorting of machine parts.

Pressure and Flow Rate Regulation Design for Pump-Tank System
Kovář, Jiří ; Němec, Zdeněk (referee) ; Svoboda,, Miroslav (referee) ; Březina, Tomáš (advisor)
The proposed work is dealing with control design of pump-tank system as part of broader water-supply network with using of mechatronic approach. The main goal of this work is design of control for regulation of flow, pressure and water level in tank in water-supply network of Vsetin city. This water-supply network consists of various components, such as pumps, pipes, valves, tanks etc. For the purpose of the control design is necessary to create a model of pipe network. The solution of hydraulic analysis is obtained by using the gradient method, which was implemented into the software solution named ADAM. The results of hydraulic analysis are compared with measured values of flow and pressure and difference of these values has to be minimalized by proposed calibration and verification process. The calibration and verification process was implemented in software ADAM. The essence of design control is formulating control problem as optimization problem. Therefore the output of higher control layer is set of procedural rules, which determines for example speed of pumps in time etc. Results were verified by using for this purpose developed computational server (ADAM Server).

Illustrative Example of Model-Based Design for Complex Aircraft Systems
Sopoušek, Radek ; Kovář, Jiří (referee) ; Janák, Luděk (advisor)
This bachelor's thesis is on the development of aviation systems, in particular their software, using model-based design (MBD) methods while maintaining recommended practices developed by the aviation industry and certification authorities (in particular RTCA DO-178C/331). The general MBD deployment options given by current aviation regulators and standards are described in the theoretical part of the work. Furthermore, this work describes what the process of developing software for a sub-segment of an aircraft system (altitude hold mode of autopilot software) could look like using the model-based design method. The overlap to the system development level (SAE ARP 4754A) is also partially addressed. The work includes an illustrative example in which system requirements were specified, software development through "Design model" and ensuring traceability between system requirements and model design.

Stress and deformation analysis of railway bridge over the Svratka River
Kovář, Jaroslav ; Žák, Stanislav (referee) ; Fuis, Vladimír (advisor)
This thesis deals with stress and strain analysis of real truss bridge structure. This structure is modelled as plane bar system. The opening part dedicates to theory, which is further used for calculations. The calculation part dedicates to compare statically determinate and indeterminate variation of structure for load by own weight and passage of the train. Analytic calculations are numerically verified with program ANSYS. In thesis is assessed concentration of stress, when the rivet drops out of the structure. The next part of thesis dedicates the spatial model of bridge, which is compared witch plane model.
