Analysis of Electric Power Consumption of Public Lighting
Varmuža, Jan ; Pavelka, Tomáš (referee) ; Paar, Martin (advisor)
The thesis deals with analysis of the public lighting system from the point of view of light sources and luminaries. It focuses on the specifics of the lighting systems such as lighting for pedestrian crossings or decorative lighting. It analyzes the energy consumption depending on daylight and how it manifests a shift sunrise and sunset on the consumption of electricity. The work clarifies how the model can be simplified sunrise, sunset for the entire Czech Republic. Based on the distribution of municipalities with population over 10,000 and modeling of sunrise and sunset calculation is carried out power consumption of lighting systems and compared to the total consumption of the Czech Republic. Simplification is an estimate of the consumption of electricity to villages to 10 000 people on the basis of the estimate, the final consumption of electricity for public lighting for the entire Czech Republic.

Energy and water demand of washing process
Barabášová, Iveta ; Touš, Michal (referee) ; Bobák, Petr (advisor)
The thesis presents a professional washing process in washer-extractor. The aim is to appoint water and energy consumption during a washing cycle based on archive data from Laboratory of energy intensive process, NETME Centre. The data have been measured during washing with steam heating and washing with electric heating. Obtained data are processed via MS Excel software and they are used for simple economic evaluation of washing cycle.

Energy sources and consumption
Majer, Jan ; Kuba, Pavel (referee) ; Bobák, Petr (advisor)
The thesis describes basic methods of producing energy and presents the basic division and characterize sources of energy. It compares and describes the production of energy in the Czech Republic and the United States of America. The thesis explains, where and how is this energy consumed and presents energy production and consumption in the Czech republic and in the United States of Amerika and provides a comparison of the two countries. Indicates the percentage of consumption in various sectors in these countries and the distribution of energy consumed by resource used. The thesis is also focused on the comparison of household consumption in the Czech Republic and the United States of America. It specifies the average household consumption of Prague and New York and investigates the causes of the difference in average household consumption of both countries.

Small boilers as a source for family houses
Studnicki, Jakub ; Katolický, Jaroslav (referee) ; Štětina, Josef (advisor)
The paper summarizes the basic parameters of boilers with low power for use in family homes. The boilers are divided into chapters according to the used fuel (gas, solid fuels, liquid fuels, biomass, pellets...). For each boiler there are basic characteristics, dimensions, methods of attachment to the wall or floor and if hot water heating is integrated. It is also characterized by a boiler heating system, i.e. the flue requirements, size and location of the water supply for heating. In another part there is an assessment of economic and environmental aspects of boilers. From an economic perspective I focus on a fuel economy and from an ecological mainly on the ratio of fuel efficiency and pollutants emitted into the air.

An empirical analysis of the impact of digital piracy on movie industry
Pernický, Tomáš ; Vozárová, Pavla (advisor) ; Rod, Aleš (referee)
By the use of questionnaire, which was filled by 516 college students, was performed an empirical study investigating impact of digital piracy on sales displacement and consumer surplus. Firstly, based on the knowledge gained from theoretical literature this thesis assesses: piracy of films increases consumer surplus by 393 CZK per capita in observed data sample. Secondly, there is a negative relationship between the first unpaid consumption which reduces paid consumption by approximately 0.06 unit. However, the second unpaid consumption increases paid consumption by 0.71 unit. These findings suggest strong influence of sampling and network effect, while both are largely caused by the possibility of digital piracy. Therefore, unpaid consumption may increase movie industry sales. Overall, this thesis concludes that digital piracy increases consumer surplus and movie market sales.
