Verification of Mathematical Model for Small Power Sources
(Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2015) Vrána, M.
This paper describes a method of verifying the mathematical model of the power supply. Simple equations describing the specific energy source. As an example photovoltaic panel was chosen. Simultaneously, there are described equation for calculating the solar radiation incident on the optionally oriented surface. These equations are used to model and convert the radiation which is recorded by meteorological stations. Reference panel and load are used for model validation. The goal of this paper is to describe a model of energy sources and its validation.

Mathematical model of heat pump
(Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2015) Pitron, J.
In this paper different energy states of a heat pump are described. Equations used for mathematical description of the heat pump in the Matlab Simulink are presented. Created model is used to calculate the energy flows in the system according to different input parameters. The simulation involves an accumulation tank, which is controlled by individual input and output parameters. Simulation results have been compared with the experimental measured values on a heat pump in a laboratory.

Luminance Analysis of Linear Fluorescent Lamp
(Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2015) Štěpánek, J.
My paper deals with theme of luminance analysis. The aim of the paper is to find out how change luminance of linear fluorescent lamps with the change of light source position. Linear fluorescent lamp will be measured in horizontal position and in vertical position. Digital camera will be used for measurement. Paper is divided into theoretical part and into practical part.

A comparison of different types of probes for detecting electromanetic emission
(Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2015) Podshivalov, A.
This paper deals with a comparison of different types of probes for detecting electromagnetic emission (EME). The matter of investigation is EME from a model which generates cracks of samples under load. This article provides a description of probes for EME measurement signals. The novelty of the approach lies in the fact that the physical model was used instead of real samples under uniaxial load of composite materials. The author also describes the experiment conducted for obtaining signals and analyses the digitized signals as waveforms and spectra. Appropriate conclusions were made according to the comparative analysis.

Short- circuit tests of circuit breakers
(Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2015) Chorovský, P.
This paper deals with short-circuit tests of low voltage electrical devices. In the first part of this paper, there are described basic types of short- circuit tests and their principles. Direct and indirect (synthetic) tests with more details are described in the second part. Each test and principles are explained separately. Oscilogram is obtained from short-circuit tests of circuit breakers at laboratory. The aim of this research work is to propose a test circuit for performing indirect test.
