Evaluating BPL Communication: A Simulation Approach
Baranyk, Matěj ; Benešl, Lukáš ; Rusz, Martin
In recent years BPL (Broadband over Power-line) technology is becoming more used. Despite the technology not needing any additional cable installation it is important to make sure that using the technology itself makes sense or what the needed requirements will be. Due to this reason, we opt to simulate almost real scenarios and compare them with outputs from network simulator ns-3. This way we can recognize the usefulness of our efforts even before we make any plans to install anything, which saves time and money. Furthermore, we can use the same simulator for diagnostics of already installed BPL routes.

Sensorimotor difficulties in children with speech impairments
Hodačová, Alžběta ; Vařeková, Jitka (advisor) ; Majorová, Simona (referee)
Title: Sensorimotor difficulties in children with speech impairments Objectives: The main aim of the thesis is to assess sensorimotor functions of children with speech disorders using standardized test batteries. Methods: 27 children were part of the study (21 boys, 6 girls), all with speech disorders from an elementary school in the age range 11-15 (12,4 years±1,05). Motor skills were tested with data collection testing batteries MABC-2, Unifittest 6-60. Furthermore, sensory functions were tested using the Nottingham Sensory Assessment. Probands were also provided with a supplementary questionnaire to gather additional information. In the next step a data matrix was created in Microsoft Excel where all data were input. Data analysis was conducted using programs Microsoft Excel and Jamovi. Results: Children with speech disorders showed higher prevalence of motor difficulties compared to Czech norms. According to the overall STS score in MABC-2 test, 63 % (17) were in the range of significant motor difficulties, which is 13 times higher than the norms. A statistically significant relationship between the Unifittest and MABC-2 was proven.In addition, a positive correlation was also confirmed between the BAL component of the MABC-2 and the long jump task in the Unifittest 6-60. Among the sensory...

Modern vibrodiagnostics of machines and evaluation of datasets by neural networks
Koníček, Tomáš ; Holoubek, Tomáš (referee) ; Hammer, Miloš (advisor)
This Master‘s thesis focuses on technical diagnostics with an emphasis on vibrodiagnostics of machines and equipment. The aim is to carry out research on vibration monitoring using modern on-line systems and to investigate the possibilities of processing the acquired data files using neural networks. Vibration monitoring from Siemens SIPLUS CMS is analyzed, including a description of individual hardware and software components. The work also focuses on machine diagnostics using a real model equipped with the SIPLUS CMS system in cooperation with the SIMATIC S7-1200 programmable automaton. The obtained data will be transferred via the FTP protocol for further processing in the Matlab program. Neural network models will be designed and used, which will be trained on the measured data. Convolutional neural network model will be used. The results will be evaluated and a conclusion will be drawn.

Preparation and implementation of construction and technical survey of a building
Mezlík, Vojtěch ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of bachelor’s thesis is a structural-technical survey of a reinforced concrete frame structure. The theoretical part deals with the inspection of reinforced concrete structures, destructive and non-destructive diagnostic methods for the diagnosis of reinforced concrete structures, and the Czechoslovak architect Jaroslav Josef Polívka. The practical part conducts a structural-technical survey, focusing on the diagnosis of the reinforcement of selected structural elements and the determination of properties of the concrete. The reinforcement was determined using electromagnetic indicator Proceq Profometer 630 and the ground penetrating radar Hilti PS 1000 and verified by chiseled probes. The concrete strength class in the structure was estimated from core drills. In the conclusion, the condition of the structure is evaluated, and measures are proposed.

Modeling and simulation of PLC-BPL communication of smart metering in Network Simulator 3
Baranyk, Matěj ; Rusz, Martin (referee) ; Benešl, Lukáš (advisor)
n recent years BPL technology is becoming more used. Despite the technology not needing any additional cable installation it's important to make sure that using the technology itself makes sense or what the needed requirements will be. Due to this reason we opt to simulate real life scenarios and compare them with outputs from network simulator ns-3. This way we're able to recognize the usefulness of our efforts even before we make any plans to instal anything, which saves time and money. Furthermore we can use the same simulator for diagnostics of already installed BPL routes. Furthermore a laboratory measurement shall be conducted in order to increase dataset sizes and to have more data that can be compared with simulation outputs.

Diagnostics of reinforced concrete construction
Slezáková, Karolína ; Hrabová, Kristýna (referee) ; Láník, Jaromír (advisor)
In the introduction of this bachelor thesis, reinforced concrete is examined, and its basic properties are described in detail. The subsequent sections focus on the methods used for diagnosing building structures. Special attention is given to the selected methods that will be applied in the practical part of this thesis. The aim of the practical part was to increase awareness of the type of material used in the examined load-bearing elements and to familiarize oneself with one of the fundamental non-destructive methods in construction.

HMI for a 3D milling machine using FactoryTalk Optix
Uher, Adam ; Foukal, Roman (referee) ; Štohl, Radek (advisor)
The thesis focuses on the design and implementation of an HMI (Human Machine Interface) for 3D milling machine. Basic visualization rules, best practises, principles of ergonomic design, and the creation of user interfaces are described. Visualization tools for the LOGIX PLC series are outlined, which can be utilized in HMI development. Following the guidelines and specified requirements in this paper, a design for HMI is created using the FactoryTalk Optix visualization tool. Changes to the functional safety and PLC program are identified and implemented. Subsequently, the visualization of the milling machine is carried out and the functions of the new system are subjected to testing.

Diagnostics of the source part of photovoltaic power plants
Turinský, Matěj ; Burian, František (referee) ; Fiedler, Petr (advisor)
The aim of this thesys is to define development requierements for HW of monitoring device for the source parts of photovoltaic power plants and afterward implement sufficient SW equipment. Thesys analyzes types of faults within a power plant its consequences and possible ways of detection. It is followed by selection of measurements and HW components for monitoring device, its complementation and implementation of control program for the evaluation unit. Program should manage a measurements with afterward diagnosis and communication with surrounding systems according to the G3-PLC standard.

Diagnostika přímého vstřikování benzínu v praxi
BÜRGER, Jan
Thesis focuses on the diagnosis of the fuel system of direct injection gasoline FSI on a training panel. Several measurements on components are described in detail, along with the procedure, results, and their description. At the end, a worksheet for students is developed for each measurement, as per the employer's request. This work will serve to evaluate these worksheets and, at the same time, can be used to improve vehicle diagnostics in practice.
