Alternative sources of nuclear energy
Svoboda, Josef ; Zlámal, Ondřej (referee) ; Katovský, Karel (advisor)
In places where it is not possible to use conventional production and distribution of energy, autonomous sources take over. Most of autonomous sources use solar energy, wind energy and other renewable resources. For applications such as special missions into outer space the usage of conventional sources is not possible. Except for powering special satellites, unconventional nuclear sources are also used in autonomous unmanned objects located in distanced areas with extreme natural conditions. It is also used in unusual propulsions of ground, water and air machine. These vehicles are for example pacemaker powered by radioisotope source, submarines, aircrafts and other vehicles supplied by nuclear reactor of unconventional conception. In this bachelor thesis there are globally summarized questions connected with unconventional sources of nuclear energy with detailed description of chosen parts. This work is concerned with finding more efficient machinery for conversion of heat energy supplied by radioisotope decay to electric energy.

Using machine vision for robot guidance
Gábik, Jaroslav ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
With the development of machine vision technologies, new applications that can increase production, versatility or simplicity of production systems are widely spread. This thesis deals with usage of machine vision for robot guidance. The task consists of creating a technique and its practical realization, where the proposed assumptions are verified. The main objective is to determine 3D position and orientation of a sheet metal part or subassembly of the body-in-white, which is lying within the reach of an industrial robot with respect to its base coordinate system. The proposed method is suitable for several types and dimensions of components, which meet certain requirements. Targeting the component is carried out by scanning significant points on the component with the help of the 3D scanner attached to the robot flange. Afterwards, gained data are processed in a designed programme. The theoretical part is focused on research in the field of machine vision, accuracy of industrial robots, compensation of their errors and manipulation and assembly of the sheet metal parts in automotive. Finally, an evaluation and recommendations for practice are provided.

Analysis of the renewable energy support schemes in the EU: Can be an ECOlogical also an ECOnomical?
Andoková, Senta ; Cahlík, Tomáš (advisor) ; Rečka, Lukáš (referee)
The study compares FIT (Feed-in tariff) and RPS (Renewable Portfolio Standard) as the two most commonly used support schemes for renewable energy sources (RES) in the EU. It examines a relationship of an Environmental Kuznets Curve (EKC) and by a practical experiment for public lighting in Prague the study proposes an ecological functioning of electricity grids in the EU with CO2 emissions reduction effect. The main contribution lies in the recency and originality of the econometric analysis and practical experiment. FIT and RPS analysis demonstrates that both schemes affect demand for electricity and increase its price. The econometric model was tested for 28 EU countries for 1990-2013. The results say that the EU is currently located on the downslope of the inverted U-shaped EKC with a turning point, after which the dependence begins to grow. Nevertheless, for the most of observations the turning point is too far to be a source of concern. Practical experiment has shown that installation of energy saving devices for electricity grids in the EU can bring satisfactory results in reducing CO2 emissions independently of state aid. More efficient use of existing energy sources, however, should rather serve as a complement to conventional support, phasing out with the development of RES technologies....
