Value stream analysis and improvement
Malec, Tomáš ; Hégr, Ondřej (referee) ; Novotný, Radovan (advisor)
This thesis deals with the general analysis and value stream improvement. The theoretical part describes the difference between functional and procedural model of company management, mutual benefits and disadvantages of these systems. The thesis deals with the mapping process, subdivision maps and methodology of process maps creation. The work also includes software analysis for process mapping. Next section contains search of selected optimization tools and methods to improve production flow and description of the principles of controlled documentation. In the practical part is realized mapping process of bachelor studies at FEKT and map of production process at ABB switchgear.

Home automation, control unit
Konečný, Jakub ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This bachelor's thesis focuses on theory about a home automation and represents the solution of the smart central server unit, designed to control wireless connected devices, read and display temperature, pressure, relative humidity data and set up automatic functions in graphical user interface. The work is more focused on the software section and describes the implementation of server technologies.

SPC for LCD monitors production
Hořký, Petr ; Kosina, Petr (referee) ; Novotný, Radovan (advisor)
Statistical Process Control (SPC) is currently the most widely used analytic methods to monitor, control and improve the quality of manufactured product. The application of SPC is demonstrated by practical example from the LCD monitor production environment with a focus on LCD backlight sources analysis. The objective is to become familiar with the applied methods and SPC software support.

Temperature Control of Heating Element with Thermocouple
Spáčil, Michal ; Novotný, Radovan (referee) ; Šandera, Josef (advisor)
Goal of this work is to develop and then build system that would keep constant temperature in a given place or that of a given material (item), in this case it would be control system for a hot air soldering station heater with output up to 600W, with required adjustable temperature range of 150-500°C. Second goal of this work is to develop and then build this device using possibly simplest wiring and as small amount of components as possible.

Design of experiments for quality optimization
Havlásek, Radim ; Kosina, Petr (referee) ; Novotný, Radovan (advisor)
This thesis is aimed to Design of Experiments methodology. Main purpose of this thesis is to create detailed materials for lessons of Design of Experiments in Quality Control courses. Thesis contains case studies which are applicable for education purposes. Design of Experiments has been applied for solder joints quality evaluation. Solder joints have been modeled in software ANSYS and finite element method has been applied for thermomechanical stress evaluation.

Processor Overclocking
Horký, Jan ; Adámek, Martin (referee) ; Novotný, Radovan (advisor)
The aim of bachelor's thesis was to describe and explain processor overclocking and its use. Suitable processor was chosen and its operational frequency was increased by increasing value of multiplier and changing frequency of FSB. Multiplier and frequency of FSB were increased by the smallest step, which motherboard allowed, to value when computer was unstable. Processor was tested by stress and performance tests for each frequency. Change of power consumption was also measured. At the end, both methods were compared.

Sensor emulation tool
Gromeš, Jan ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The goal of this thesis is design of platform capable of sensor output emulation. The platform allows to emulate either digital sensors, communicating over UART, SPI, I2C, CAN and RS-485 buses, or analog sensors and sensors with frequency output. Design of computer interface to configure the platform is also a part of the thesis. Special emphasis is placed on the universality and overall user-friendliness of the entire system.

The automatic self tuning system for seven-string guitars
Jeřábek, Vojtěch ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The thesis describes a realization of the automatic self tuning system for sevenstring guitars. There are comparisons of commercial and uncommercial solutions for six-string guitars. There is also evaluation of useful parts for seven-string guitars. Thesis contains a description of a requirements for individual parts and a control software with respect on real guitar properties and used computing algorithm. In the second part of thesis, there is a description of final system design and its realisation including the control software. This is also related with testing of the entire system.

Development localization board
Szabó, Michal ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This document describes a device capable to determine geographical position thanks to its GNSS module and measure the change of movement with the help of an accelerometer and gyroscope. Outputs of these integrated circuits are combined, data are processed and fused thanks to a numerical integration and mathematical filters. Results are stored on a memory card. The whole development is described from a concept, through the making of the device and software algorithms to the testing of its functions.
