Investigation size effect of negative active mass additive on service life lead-acid accumulator.
Mikoláš, Jiří ; Novák, Vítězslav (referee) ; Bača, Petr (advisor)
The task of research work is to study new mechanisms and to minimize disturbance of lead batteries for hybrid electric vehicles. Those arising under the PSoC (Partial State of Charge) and is linked to irreversible sulphation mainly negative electrodes. As one solution to prevent sulphation of the negative electrode appears to be the active ingredients in a negative matter. In the investigated electrodes is verified the influence of carbon, titanium dioxide and silica on the grain size of the order of nanometers.

Impact of the climatic conditions upon the varnishes properties
Mikoláš, Jiří ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
This bachelor's project analysis influence of moisture absorption on dielectric properties of composite material, which was exposured various relative humidity. The composite material consist of epoxide varnish EPOXYLITE TSA 220S by company Epoxylite Ltd. with various weight percentage number micro-ground mica. This experiment was carried out by dielectric relaxation spectroscopy with frequency range from 100 Hz to 1 MHz. Elementary results of this project are composite material frequency dependencies of component part of complex permittivity.

From board games to teambuilding
Mikoláš, Jiří ; Hnilica, Karel (advisor) ; Hubáček, Ondřej (referee)
The Outline of the development and history of a board game. The Mapping of the contemporary situation in the field of board games. Cultural, social and psychological aspects of playing board games. Defence of the stand that board games are not marginal subject beside modern sorts of amusement e.g. computer games. The Classification of modern board games with regard to their dominant cultural background and origin. The sociological survey on board games and motivation to their playing in the subculture of players 10-15years old. The Analysis of the survey and a search of basic categories of associated motivations for positive relation to board games and their playing. More detailed view on reasons why people do not want to play board games. The Analysis of players' fellowship. The practical application of board games (like general educative tool, a tool in the scope of teambuilding and human resources or else expert diagnostics and therapy). Keywords a subculture of players, a modern classification of a game, a board game, a table game, the history of board games
