Financial return of home photovoltaic power plant
Jančík, Josef ; Malý, Milan (referee) ; Mauder, Tomáš (advisor)
This thesis if focused on return on ivestment evaluation of a photovoltaic system of residential house. The calculation is made for photovoltaic system with and without accumulation and in combination with other alternative source – heat pump. The costs of instalation and working of new systems are then compared between each other and with the cost of working of a current system without photvoltaic.

Bus wiring systems for complex building management
Mokrý, Lukáš ; Macháček, Jan (referee) ; Bátora, Branislav (advisor)
The aim of my thesis is to examine current opportunities of bus wiring systems for complex building management, mainly its power and economic evaluation. It can be simply called intelligent electrical installation. I will examine two systems from INELS and ABB company. These systems contain functional components, mainly modules and controllers. By means of other materials, I’ll create a panel. Components will be placed there and electrically connected. After this, systems will be put into operation and programmed by means of their software. The next step is measuring of quatities during the various conditions of systems and consumption, which is one of the main aims of the thesis. Two apparatuses will be used for measuring. This thesis itself will contain theoretical analysis of systems, their description, using the way of operation and main advantages and disadvantages. Single components and complete process of measuring and working in laboratory will be described. An overall evaluation and comparison of the systems from various points of view, including the price, will be put together from results.

Linux kernel operating system optimization for battery-powered devices
Lefler, Přemysl ; Komosný, Dan (referee) ; Benedikt, Jan (advisor)
his thesis focuses on optimization of Linux-based operating system for a accumulator-powered device Raspberry Pi 4. Compared to other devices commonly used in Internet of Things projects, the Raspberry Pi 4 offers many functions within one device. However, the disadvantage is the high consumption of electricity. The aim of this thesis is to achieve greatest possible savings in electricity consumption of the Raspberry Pi 4 device, with regard to functionality of the device as a server for data collection from sensors.

Android app - Energy Monitor with Prediction
John, Tomáš ; Herout, Adam (referee) ; Szőke, Igor (advisor)
The thesis describes process of creation mobile application used for recording and processing data from consumption energy meters. Application targets on devices with operating system Android. The task was to study similar solutions and then design and implement own one. Enriched by the possibility of predict future energy consumption, using historical outdoor temperatures. Also bring the optional OCR (Optical Character Recognition) reading meter's values. Weather data obtain from internet weather service. And from stored data be able to make user- rendly charts and statistics showing energy consumption.

Automatization of Analysis of Performance and Power Consumption
Rudolf, Tomáš ; Jaroš, Jiří (referee) ; Nikl, Vojtěch (advisor)
This thesis deals with increasing efficiency of supercomputers. Higher efficiency can be achieved by reducing frequency of processor if the algorithm does not slow down significantly. This thesis presents set of scripts designed to monitor consumption of processor along with scripts that visualize these measured values. It also allows easy control of processor frequency. The created solution gives user a capability to measure given algorithm efficiency and optimize computing power of specific computer exactly for the algorithm. Due to this work the user will be informed about whether it is advantageous to run his algorithm on one or other frequency of the processor.

The Use of Statistical Methods for Data Processing
Čupr, Jiří ; Klučková, Martina (referee) ; Novotná, Veronika (advisor)
This master's thesis is focused on problem of orders of ingredients in McDonald's. It's an analysis of usage changes depending on outside temperature. Thesis includes theoretical background for correct analysis of the problem and possibilities to figuring it out. There is also an algorithmus for more efficient solution of problem with needs or excess of ingredients. There is also a program written in VBA language, that makes more simple usage of this algorithm on restaurants.

Wireless sensor network
Šťáva, Radek ; Šteffan, Pavel (referee) ; Pavlík, Michal (advisor)
The main theme of this work is to design and make a modern network of wireless sensors, when the main used circuit in the sensor module and the receiver module is microcontroller Texas Instruments CC430F513x. Care is taken primarily at very low power of sensor module for long battery life when on battery power. It is also emphasis is on reliability involvement of miniature size, expandability and high precision modules of basic sensors.
