SmartFlat peripherials
Chytil, Jiří ; Jirgl, Miroslav (referee) ; Bradáč, Zdeněk (advisor)
The theme of this thesis is the design of peripheral devices of a smart home SmartFlat and the design of communication interface for this system. Designed units are the humidity and temperature measuring unit, the unit of security and the smart socket unit for remote control, power measurement and power control. All units are designed for wired communicaton and also for wireless communication with control unit.

Memory Management in Linux
Tuček, Jaroslav ; Kočí, Radek (referee) ; Vojnar, Tomáš (advisor)
This work describes the memory manager subsystem of the linux kernel. The first part gives a brief account of operating systems architecture and memory management theory - of virtual memory management, page tables, page replacement algorithms and kernel allocators in particular. The second part discusses the actual implementation of these principles in a modern kernel - in linux. Finally, a series of tests stressing the memory subsystem is conducted to determine the memory manager's real behaviour. Limitations of the current linux kernel memory management and some of their proposed solutions are also discussed.

Application for Worktime Monitoring and Reporting
Šlapák, Jiří ; Škoda, Petr (referee) ; Malý, Jakub (advisor)
This bachelor thesis studies the management of software development, reporting and tracking work of developers. The basic ideologies for this thesis are agile methodologies Scrum and Kanban. The combination of the two is called Scrumban. The final result of this thesis is an intuitive web application called Scrumban Board, which offers a way for team management, planning tasks for teams and tracking efficiency of the development. The second part is a minimalistic application called Scrumban Client for the Windows operation system. This application offers an easy way of tracking work time.

Intelligent Energy Measurement Device
Mrázek, Vojtěch ; Sekanina, Lukáš (referee) ; Vašíček, Zdeněk (advisor)
The goal of this project is to design an energy measurement device that supports logging of historic values and offers simple analysis of the values. The proposed device enables to display actual quantities such as active and reactive power, current or even power factor. In addition to that, it also stores the energy profile that can be subsequently analysed. The device communicates locally via USB or remotely via Ethernet.

OpenGL Performace Meassurement Tool
Rehorčík, Pavol ; Polok, Lukáš (referee) ; Pečiva, Jan (advisor)
This thesis talks about theoretical and practical side of development of testing application for OpenGL performance with focus to shaders. In theoretical part are individually described used techniques and principle of usage of shaders. The core of thesis is practical part, so creation and implementation of this application. In final part I discuss measured results and possible extensions.

Advanced Tools for Performance Measurement
Smrček, Jaromír ; Gajda, Zbyšek (referee) ; Kašpárek, Tomáš (advisor)
This thesis presents the I/O layer of Linux kernel and shows various tools for tuning and optimization of its performance. Many tools are presented and their usage and outputs are studied. The thesis then focuses on the means of combining such tools to create more applicable methodology of system analysis and monitoring. The practical part consists of applying SystemTap scripts for blktrace subsystem and creating a fragmentation monitoring tool with graphical output.

Experimental measuring of model house lift
Kalina, Martin ; Feiler, Zdeněk (referee) ; Koláčný, Josef (advisor)
This work describes a model of a house elevator with an EC motor ( Electronically Commutated Motor) and a programme essential for controlling of the model and adjusting of the protective features for a safe operation. The work deals with experimental measurement based on the model, firstly while being at idle run, and then while being loaded. It is focused on the identification of influencing the EC motor input by usage of the counterweight. The aim of the work is to process the measured data, which are then used for mechanical adaptation of the model and the consequent confrontation between the measured data gained before and after the adaptation. Also an important part of the work is the simulation of the elevator using the 3D SolidWorks Programme.

Control of c.h.p. unit
Ulver, Martin ; Sutorý, Tomáš (referee) ; Kolka, Zdeněk (advisor)
Master’s thesis deals with cogeneration unit and its control. Cogeneration unit used to energy production and heat production. Power of cogeneration unit is controlled by current consumption of the building, so that the absorbed power from the public network to a minimum. The control unit is composed of two individual part, which is communicated together along single phase of the ~230V. One part measure absorbed power of the network and the second control a cogeneration unit.

Electric drive of lift model with EC motor
Kutrucz, Tomáš ; Procházka, Petr (referee) ; Koláčný, Josef (advisor)
This diploma thesis describes a simulator of home elevator driven by an EC engine (external combustion engine). The introductory chapter of the thesis deals with the history of elevators. It also contains the description of EC engines, the description of the construction of the simulator and of the mechanical, electrical, and software adjustments carried out as based on the thesis. The main part of the work concentrates on the description of the changes of the drive algorithms, the production of the 3D simulator and the animation in the background of 3D Solid Works. Moreover, it also deals with the experimental performance measurement based on the loading of the stimulator drive.

Dynamometer for measuring power of IC-engines
Mikulášek, Tomáš ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
The aim of the work was to summarize the development of a system for measuring the power of internal combustion engines, from the initial simple dynamometers, to modern electronic devices with flange strain gauge for sensing torque compared their advantages and disadvantages, usability, efficiency, performance and manageability. Furthermore there was performed comparison with the standards dealing with this issue. Use of these devices is available, subject to atmospheric conditions specified in standard and manufacturer.
