Optimalization of somatic presumptions for artistic gymnastics
Růžička, Martin ; Krištofič, Jaroslav (advisor) ; Marek, Jaroslav (referee)
The Name of The Thesis: Optimalization of physical preconditions m Artistic Gymnastics The Objectvive of The Thesis: To analyse and evaluate data obtained by testing of individua! physical parametrs of men's and juniors' members of The Czech Republic national team relating to demands ofArtistic Gymnastics. Method: We use modification of Sheldon's Method by Carter and Heath to set up the somatotype. Individua! measured values of gymnasts and their diffusion are represented in one somatograph. Each measured item is compared with general population in graph. Values of juniors are compared with values gained from official materials of FIG. We use Matiegka's method to determine the percentage ofindividual physical tissues Results: Graphs containing results represent valuable information for coaches of men's artistic gymnastics in relation to the choice of talented individuals and to the optimalization ofphysical preconditions. Key words: Artistic Gymnastics, Somatotype, body constitution, rnen, juniors. 3

Particle systems
Růžička, Martin ; Kmoch, Petr (referee) ; Pelikán, Josef (advisor)
The presented work deals with the issue of particles. It aims to offer a system for particle creation, simulation and visualization. The introductory part of the paper is devoted to design a physical model. The physical model particularly stresses a fast and at the same time plausible approximation of physical laws. Afterwards, it deals with methods of describing the particle behavior. In order to achieve the highest possible flexibility, a scripting interface is used. The conclusion then describes the visualization of the final particles itself. It is realized using the designed extension of the OpenGL graphic library. The results of the work can be seen in an enclosed application which demonstrates the possibilities of the designed particle systems.

Fluid and structure interaction
Růžička, Martin
The subject of this thesis is the numerical simulation of the interaction of two-dimensional incompressible viscous flow and a vibrating airfoil. A solid airfoil with two degrees of freedom, which can rotate around the elastic axis and oscillate in the vertical direction, is considered. The numerical simulation consists of the finite element solution of the Navier-tokes equations coupled with the system of ordinary differential equations describing the airfoil otion. The time dependent computational domain and a moving grid are taken into account with the aid of he Arbitrary Lagrangian-Eulerian (ALE) formulation of the Navier-Stokes equations. High Reynolds umbers up to 106 require the application of a suitable stabilization of the finite element scretization. Numerical tests prove that used method is sufficiently accurate and robust.

Didactic Motivation in School Physical Education
Růžička, Martin ; Fialová, Ludmila (advisor) ; Velenský, Michael (referee)
Didactic Innovations at School Physical Education (Teaching the Games) Objectives work To analyze the opinions of current PE teachers on the concept and content of teaching sports games secondary schools, identifying key problems, propose a solution and appropriate teaching practices the teaching of games in secondary schools. A method The analysis was carried out by questionnaire in a 36-PE teachers in secondary schools during the month of May 2006. The questionnaire focused on The following areas, which involve issues related to the teaching of games in secondary Schools: The Role of sports games, sports games teaching content, didactics of sports and games social interaction in games. results Illuminate the teaching of games in secondary schools, they can contribute to its improvement and assist teachers in assigning sports games in the program. Can be the basis for a proposal modification of teaching sports games in terms of pupil assessment, time allocated to teaching unit and other factors examined, and may also be beneficial for the quality of future educators. Keywords Didactic innovation questionnaire, sports games, school TV learning. Powered by TCPDF (www.tcpdf.org)

Structural design of the testing centre
Růžička, Martin ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The master´s thesis concerns with the design of the construction of the testing centre. The hall is divided in two parts, in one of those parts the office rooms are located. The precast concrete frame of the hall is composed by foundation pads, columns, secondary beams and crane beams, precast slabs, and prestressed girders. The thesis contains report, structural design, drawings of floor plans and sections, drawings of formwork and reinforcement, visualization and steps of construction.

Inverted Aircraft Engines
Růžička, Martin ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This thesis deals with inverted aircraft engines. Introduction contains overview of general requirements for aircraft engines, their division and basic information about inverted construction. In second chapter there is overview of selected engines with inverted construction, their description, technical specification and eventually modifications. Conclusion consists of chapter elaborating on description of different construction and their comparison with performance-wise similar invert engines.

Memory monument from prefabricated elements
Růžička, Martin ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The bachelor‘s thesis is concerned with a design of a monument which is made of reinforced concrete. The monument is composed of eleven prefabricated segments located from each other in regular distances. The segments have got the same external dimension but they differ in the dimension of internal openings which create a dynamic interior for a person standing inside of the structure. The segments are fixed to the prefabricated comb-shaped foundation. The aim of this thesis is to design each segment and the foundation of the construction. It also includes the technical drawings of reinforcement of the selected segments, the foundation, drawing of the concrete connection of the foundations and drawing of the shape of the segments.

Study of DNA oligonucleotides interactions with ethidium bromide by partial-filling affinity capillary electrophoresis
Růžička, Martin ; Koval, Dušan ; Kašička, Václav
A partial filling affinity capillary electrophoresis was developed and applied to investigation of non-covalent molecular interactions between double stranded DNA oligonucleotide (Dickerson dodecamer) and classical DNA intercalator ligand –ethidium bromide (EtBr). Binding constants of DNA EtBr complexes were determined from the dependence of migration time changes of DNA oligomer (applied as analyte) on the length of ligand zones introduced beforehand as plugs of various lengths in hydroxypropylcellulose coated fused silica capillary. Binding constants of DNA-EtBr complex were found to be in the range 4.2 x 103 – 1.5 104 L/mol.
