Luminaires and Applications with Power LEDs
Vaňko, Adam ; Pavelka, Tomáš (referee) ; Baxant, Petr (advisor)
Progress in development of modern LEDs, their long lifetime and high luminous efficacy predetermine them for usage in lighting systems. This master's thesis examines possibilities of application of LEDs in luminaires, parameters of diodes and problems, which can appear in construction of luminaire with LED lighting source. In the practical part of this thesis a luminaire is designed, capable of illuminating traffic signs, vertical surfaces, billboards and fasades. By standards required parameters of a lighting system and adaptability of application must be considered in complex predesign. Simulations of lighting scene, created in special computer software, measurements of optical point’s parameters and construction of real luminaire model using high quality CREE LEDs, are included in analysis of the problem. Parameters of the luminaire were proved by measurements of product’s attributes at light laboratory. There are also some suggestions for improvement and further development of the product.

Skin surface water temperatures determination in selected lakes and reservoirs from satellite data
Formánek, Tomáš ; Kolář, Jan (advisor) ; Brodský, Lukáš (referee)
LAKE SURFACE TEMPERATURE DETERMINED BY SATELLITE IMAGES Abstract The aim of this master thesis is to create a method to determine surface temperature of water in lake Osoyoos (LSWT - Lake Surface Water Temperature). It is necessary to know this temperature in order to make easier decisions in a paradigm of global warming processes. Thanks to LSWT it is possible to make a timeline visualisation of temperature development in years. The first chapter deals with a physical definition of how to get thermal information - the basis of remote thermal sensing is measuring of radiance intensity and it's transformation to brightness temperature. This radiation is not only influenced by atmospheric properties but also by local climatic and meteorological conditions, but it is also influenced by the relief. The thesis seeks to create a method for calculating surface temperature of lake Osoyoos located at Canadian-American border. This calculation is based on data provided by ASTER using a split-window method. The method works with the differences in bands of sensing in order to remove atmospheric influences. This thesis contains several charts, graphs and pictures. The final result of this paper is a map of distribution of lake surface water temperatures. Keywords: Thermal remote sensing, land surface temperature, ASTER, TIR

Issues of application and acceptance of TIR Carnet on the territory of Russian Federation.
Pushkareva, Veronika ; Novák, Radek (advisor) ; Rathouský, Bedřich (referee)
Master's thesis is dedicated to one of the most effective international treaties, which attends to facilitating and liberalization of international handling with goods, functioning for almost 40 years. This paper mainly describes the situation, which appeared in 2013, when the barriers for its application emerged. It tells about the crisis of TIR Carnet on the Russian territory, caused by some intern factors as well as factors on the international level. Affairs and changes, arisen in the beginning of the 21st century (expanding of the EU, new goods transportation methods, Customs Union, etc.) drove to the loss of TIR treaty's significance, and to the necessity of creating new international cooperation principles. Situation then changed due to the civil war in Ukraine, sanctions against Russia and Russian response. That is why the ground, reasons and consequences of TIR Carnet crisis on the Russian territory were in detail described in the master's thesis. Main conclusion is that this crisis only predicts the beginning of serious changes in international transport of goods, which can be faced in the nearest future.

Legal relations in transport of people and goods
REZKOVÁ, Ivana
This thesis revers to the Legal relations in transport of people and goods. The introducy chapters are described types of transports. The major part of this text is dedicated to the international and inland treaties. In the practical part of this thesis directs its attention at clarifying essential parts of Agreement ADR and shows the application of Agreement ADR.In the closing part the autor indicates the necessity for a collaborative development of contracting states in Agreement ADR.
