Nordic walking - gait analysis of older adults.
Novotný, Petr ; Vilímek, Miloslav (advisor) ; Horák, Zdeněk (referee)
Title: Nordic walking - analysis of senior walking Aims: This thesis aims to make a kinematic and kinetic analysis of gait and NW in elderly using Qualisys and Kistler. Afterwards, it also aims to compare the selected parameters with each other and, based on the results, to objectify the effect of NW on the gait of the elderly. Methods: The theoretical part of this thesis was processed using books and electronic sources obtained from online databases (PubMed, Medline, and Google Scholar). The research part was done in the form of an experiment. Fifteen women aged between 65 and 83 years (mean age 74) who regularly practiced Nordic walking under professional guidance participated in the research. These women were measured while walking and NW. A 3D kinematic analysis of walking and NW was performed using the Qualisys Motion Capture camera system. Ground reaction forces were measured using Kistler force plates placed in the captured kinematic analysis path. Data from these instruments was processed in Qualisys Track Manager and Microsoft Office Excel. Selected gait parameters that were analyzed included stride length, double-step length, gait speed, stride cadence, standing phase duration, lateral pelvic deviation, hip flexion and extension, knee joint flexion, dorsal and plantar flexion of the ankle...

Nuclear power plants and their safety
Novotný, Petr ; Köbölová, Klaudia (referee) ; Milčák, Pavel (advisor)
The bachelor thesis deals with the current state of nuclear energetics. It describes the development of nuclear power plants to date and specifically describes the most commonly used types of nuclear reactors. Most of the reactors currently in operation are second generation reactors. However, a number of third-generation reactors with improved technological and safety parameters are already under construction. Improved safety lies in the improvement of active safety systems, but also in the increased use of passive safety systems. The paper concludes with a comparison of specific solutions from the most important nuclear reactor manufacturers in the world.

Motorcycle rotary engine
Novotný, Petr ; Rozsíval, Jan (referee) ; Zháňal, Lubor (advisor)
Diploma thesis is focused on conceptual design of Wankel rotary engine with performance between 30-60 kW. Performance of designed engine is determined to 35 kW and volume of one chamber amounts to 245,58 cm^3. In this thesis are step by step calculated geometrical properties of each design group which are afterwards put into 3D data. There is also solved cooling system of designed engine and design of geometrical and characteristic properties of parts of cooling system. Last but, not least there is solved placement of designed engine into frame of motorcycle. As suitable motorcycle has been chosen Honda CBR125R because it has very advantageous layout of frame.

Safety assessment of NHX5500 DMG MORI machining center
Novotný, Petr ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma thesis deals with legislative purposes for the operation of machinery in the Czech Republic and the European Union. It deals with the analysis of technical standards of machinery, specific machining centers. The analysis of the risky machining center NHX 5500 DMG Mori is based on this. The result of the work is the minimization of ongoing risks and meeting the legal requirements of the state of the operated machining center.

Systems for performance flow distribution in vehicles powertrain
Novotný, Petr ; Suchý, Jan (referee) ; Fojtášek, Jan (advisor)
The bachelor thesis tries to provide compact knowledge about differential systems. In the first part of the thesis you can find information about basic function and differentials are divided into several groups. Second part describes elementary kinematic and torque quantities which have significant influence on the character of differential. Last part of my thesis is concerned with groups of differentials mentioned in the first chapter. Also in the last part there is place devoted intelligent differentials which are nowadays on a market.
