An Innovative Control System for Water Supply Management at a Farm
Doležal, Aleš ; Sýkora, Tomáš (referee) ; Jirgl, Miroslav (advisor)
The thesis deals with the implementation of an innovative control system for the management and supply of water to the farm. For the innovation, fiber optic communication between the main switchboard and the poles at the wells was chosen. Furthermore, the thesis deals with the selection of components and sensors for the implementation of the system. The program that controls the whole application is written in ladder language in a development environment from Unitronics, from which the control PLC is also supplied.

Visualization of exit inspection of the production line for seats
Čambál, René ; Jirgl, Miroslav (referee) ; Sýkora, Tomáš (advisor)
This thesis focuses on the design of an output control system for the production line of automotive seats at Lear Corporation Seating Slovakia. The approach to line design is based on the principles of lean manufacturing, emphasizing efficiency, quality, and optimization of manufacturing processes. The main goal of this thesis is to create software and HMI (Human-Machine Interface) visualization for virtual testing in the pre-series phase of the project and subsequent real-world use by individuals in the manufacturing environment. This approach enables effective identification and resolution of potential issues and optimization of manufacturing processes in the early stages of development. Additionally, attention is given to the process design of the line to achieve an optimal balance between speed, precision, and flexibility. The proposed line design aims to maximize manufacturing efficiency, minimize waste, and ensure high product quality. The overall outcome of this thesis represents a comprehensive and integrated approach to the design of a conveyor line for automotive seats, serving as a model for future projects in the automotive industry.

An investigation of lubrication of knee joint replacement
Sýkora, Tomáš ; Horák, Zdeněk (referee) ; Nečas, David (advisor)
This diploma thesis deals with an experimental analysis of knee joint replacement lubrication. The experiments were realized at a knee joint simulator which can apply conditions according to certain standard and survey the phenomena by using fluorescence microscopy. The aim of thesis is to clarify the influence of particular components of synovial fluid on the lubrication process. The intensity of fluorescence expresses dimensionless parameter of a lubrication film thickness. There was a fundamental study with mineral oils before the experiments with the synovial fluid. The study allows to have a look at contact transformation during walk. Results are shown in graphs as dependency of intensity on time, including pictures showing phenomena in the contact zone. Experiment results show that protein -globulin creates a layer on the surface. There is albumin on the layer and it makes the lubricating film thicker. The protein interaction is supported by hyaluronic acid and fosfolipids which stabilizes the created structure. According to lubrication is behaviour of film related to a complex structure of synovial fluid. Thesis gives more information about behaviour of synovial fluid and can be used for future development of knee replacements.

Electronic business card/price tag with wireless communication
Sirůček, Václav ; Sýkora, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
The Bachelor thesis deals with the design of an electronic business card, a portable imaging device that will display data about the wearer (name, surname, phone number and email). Claims are for long-term battery life and remote display of data on an electronic ink display. At work there is a solution for powering the product with a display and its wireless communication with the computer or phone. It also deals with battery status displays, display updates, circuit schematics, electronic business card case design and final realization.

Stress strain analysis of membrane coupling
Sýkora, Tomáš ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This master’s thesis deals with the strain stress analysis of a membrane coupling with different membrane shapes and under different operating conditions. Thanks to their flexible membrane, these couplings are able to transmit torque even in the moment of misalignment of the connected shafts. However, too much misalignment is one of their most common causes of failure. For this reason, it is necessary to define the critical areas of the coupling during the design and to reduce these areas with the right optimization. For this purpose, a geometric and subsequently a numerical model of the membrane coupling for simulations using FEM software Ansys Workbench is created. At the beginning, the initial shape of the membrane is determined and according to the results of individual simulations, the shape is gradually optimized. At the end of the thesis, based on the distribution of equivalent stress in the membrane, the results of individual optimizations are compared and evaluated.

Mobile Robot Localization in Indoor Scenarios
Sýkora, Tomáš ; Brejcha, Jan (referee) ; Beran, Vítězslav (advisor)
The goal of this project was to create a software for an autonomous mobile robot capable of navigation in indoor scenarios and of detection and recognition of the objects on its way. An important condition that the final software had to meet was to find the cheapest solution possible. I achieved the given goal and its conditions using an open source software framework Robotic Operating System (ROS) and its tools. The final system is a set of ROS modules communicating with each other, using a single sensor as an input data stream and a small motor which is able to send information about its velocity and rotations to the control part of the system. This mobile robot can, without any significant problems, navigate through a mapped area while trying to find trained objects. Such a robot could be easily used (after adding specific mechanical parts) to help retired or disabled people, to cooperate with industry workers or in many other fields.
