Design of Flow, Temperature and Pressure Measuring System
Macíček, Ondřej ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

New Solutions for Settings Car Headlamps
Glatter, Willi ; Straka, Ivo (referee) ; Kalivoda, Milan (advisor)
The aim is to develop new adjusting element. There were three versions of engineering design suggested, which were consequently simulated for various materials. Optimal material was chosen and came up to production suggested variants. These variants were consequently implemented to the headlamp and were consequently measured and tested. During measuring was under consideration change of CutOff line position after heat imunity and vibration tests. Result is selection only one material and only one engineering design of adjusting element solution, which warrants easy and fast assembly and confidential adjusting of reflector, for standardization and implementation to recently develop headlamps.

Monitoring of buildings in relation to surrounding construction activity
Ledvoňová, Monika ; Heřmánková, Věra (referee) ; Cikrle, Petr (advisor)
This thesis deals with the monitoring of buildings disorders caused by surrounding con-struction activity. The first section describes the methods of monitoring failures, from the detailed inspection to the result evaluation, there is also given an overview of measuring instruments. The second part describes the methodology of passports implementation and contains an example of the object repassport that was violated by tunneling. There is a comparison of passport and repassport. The third largest section describes a practical ex-ample of monitoring object cracks around which the building activity took place. There is a documentation of failures, a description of the measuring spots choise, installation of the bases, monitoring, processing of results and conclusion.

Optimization of Run Configurations of k-Wave Jobs
Sasák, Tomáš ; Jaroš, Marta (referee) ; Jaroš, Jiří (advisor)
This thesis focuses on scheduling, i.e. correct approximation of configurations used to run k-Wave simulations on supercomputers from the IT4Innovations infrastructure. Especially, for clusters Salomon and Anselm. A single work is composed of a set which contains many simulations. Every simulation is executed by some code from the k-Wave toolbox. To calculate the simulation, it is necesarry to select a suitable configuration, which means the amount of supercomputer resources (number of nodes, i.e. cores), and the duration of the rental. Creation of an ideal configuration is complicated and is even harder for an inexperienced user. The approximation is made based on the empiric data, obtained from multiple executions of different sets of simulations on given clusters. This data is stored and used by a set of approximators, which performs the actual approximation by methods of interpolation and regression. The text describes the implementation of the final scheduler. By experimenting, the most efficient methods for this problem has found out to be Akima spline, PCHIP interpolation and cubic spline. The main contribution of this work is creation of a tool which can find suitable configuration for k-Wave simulation without knowing the code or having lots of experience with its usage.

Force loading of milling tools during the machining process
Švec, Michal ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
This thesis compares the force load of two kinds of cutting tool inserts while milling. The thesis is devided into two main parts – research and experiment. The research part is focused on the theory of the force load measuring, cutting tools and cutting tool inserts and their coating. 14 grooves were made with each cutting insert while the force load was measured. Constant cutting conditions were applied. The experiment was repeated four times for each kind of cutting insert. The aim of the thesis is to determine if both kinds of inserts mill with the same force load. The results reveal that one kind of cutting tool inserts mill with the force load higher up to 85 %.

System for Recording and Reporting Fault States of Cooling Devices
Jašek, Filip ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
The thesis deals with the design and creation of a system for recording and reporting error states of cooling devices on the principle of a compressor heat pump. An important element of the concept of the entire monitoring system is a built-in platform based on the ESP32 microcontroller for evaluating data measured by sensors. Another key element is the communication module, which sends measured data via GPRS in the form of MQTT messages to the service web application. The application receives, evaluates and records measured data. Subsequently are measured data and evaluated error states presented to the user in the form of tables and interactive graphs.

Design of a 3D scanner for educational purposes
Paprsek, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
The aim of the submitted semestral project is research of 3D scanning object methods. The 3D scans utilization and types of these scans have been mentioned in the first chapter. The scanners are grouped into two basic methods – contact and contactless. The second chapter is dedicated to 3D model measurement principles, which are described in detail in four sub-chapters. In the following chapter is described design with complete realization 3D scanner with the implementation of the application for its controlling. Last part of the thesis concerns the 3D model editing and method evaluating.

Electronic instrument for environment monitoring during plants growing
Žák, Jaromír ; Kuchta, Radek (referee) ; Hubálek, Jaromír (advisor)
The main goal of this project is to make electronic instrument for monitoring environment during plants growing for Mendel University of Agriculture and Forestry in Brno. The new device will replace current analog recorder of temperature and humidity. New device will be extended by measuring atmospheric pressure, illumination and CO2 concentration. Main advantage of electronic measuring is better lucidity of gained values. New concept allows easier comparison new values with earlier measured data.
