Model for energy control from solar panel
Hromek, Jiří ; Dvořáček, Martin (referee) ; Malounek, Petr (advisor)
This is specifies problems of electricity development from the sun. It informs about the principles and especially means of optimizing of extracting maximum. There is created a prototype in the Matlab/Simulink environment representing a source of radiation and a solar panel. A prototype output is an extracted voltage for a different angles of panel tilt compared to a light source and a different lighting intensity. A prototype is practically realized then. Then there is devised a procedure of prototype for a maximum voltage extracting from solar panels. A prototype is liable to connect to the programmable controller of B&R company.

Vliv stájového mikroklimatu a intenzity osvětlení na mléčnou užitkovost a reprodukci holštýnských dojnic ve vybraném chovu
Fábry, Ivan
This bachelor thesis focuses on stable microclimate and lighting intensity and their effect on milk yield and reproduction parameters of cattle. The literature review was focused on the parameters of the stable microclimate, milk yield and reproduction of cattle and the factors that influence them. In the practical part was evaluated the correlation between temperature, lighting intensity and parameters of milk yield (milk quantity and composition) and reproduction (length of service period, percentage of pregnancy). The data presented in the practical part of the bachelor thesis come from a specific farm in the Zlín region. Temperature and light intensity were measured by Minikin RTi/QTi sensor, which was placed in the selected stable. The data were continuously downloaded and analysed by mathematical and statistical methods to evaluate the correlation between the measured data and the parameters of milk yield and reproduction.

The impact of architectural lighting on the environment of NKP Vyšehrad area
Kučera, Patrik ; Kárníková, Hana ; Maierová, Lenka
Architectural lighting performs an aesthetic function, accentuating the significance of historic buildings or important public spaces. At the time of the creation of historic buildings, the artificial night lighting of facades was neither affordable nor technologically feasible. The architecture was designed for daylighting, which is dynamic and creates different shadows and contrasts. With the coming of new powerful LED sources, lighting is becoming more and more involved in the atmosphere of the night environment, not only on festive occasions but also permanently. Intense cones of light create new, foreign elements in the nightscape. The increase in the frequency and intensity of electric lighting in the night environment contributes to light pollution that burdens nature and degrades the cultural landscape. The study analyses the illumination of the historic buildings of the Vyšehrad, assessing the effect of lighting on the monumental value of the buildings and the degree of interference with the natural environment of the park. Using brightness analysis, it monitors the adequacy of light use, identifies excessively illuminated areas, and places at risk of glare from light sources. The results demonstrate the contribution of architectural lighting to light pollution. Highintensity lighting and placement of light sources that do not support the plasticity of architectural detail affect the historical context in the environment - high contrasts affect visual comfort and user orientation. Light cones encroaching into the tree canopy have a negative impact. The excessive intensity and inappropriate direction of light are also detrimental to the wider context of the city.
