The thesis titled Analysis of factors affecting the efficiency of the maintenance of ornamental vegetation and park areas using small machinery is addressing the issue of evaluation of effects of the factors which determine the performance of deployed equipment. In evaluating the performance of cutting machines, bush cutters, and hedge trimmers we have considered the effects of terrain segmentation and steepness in the locality, the character, plant species, and size parameters of the growths as well as the technical condition and design of machinery. The processed results then became the basis for the calculation of coefficients expressing the effect of each monitored factor on the performance of a given type of machine. Developed methods for 5-level evaluation of growths represent an original way of assessment of diverse factors on the performance of the machines by quantifying them. The proposed coefficients are clearly grouped so as their use under normal conditions of green areas maintenance is simple and practical. These coefficients are developed for the use of lawn tractors, riders, hand held mowers, hedge trimmers, hedge trimmer attachments, and brush cutters, and have been tested in practice. The identified and verified coefficients permit to evaluate the effects of selected factors under real-area conditions and determine the actually achieved performance. In the framework of the management of green areas maintenance their use is appropriate for the correction of performance of used machinery for more precise economic calculation of prices of maintenance works and deployment of equipment and personnel. The results of the work are also useful in garden, park, and landscape design and implementation where they can define the spatial distribution of vegetation elements with respect to the effective movement of machinery during maintenance.

The master thesis is focused on measuring of cutting forces and milling on the CNC machine SCM Tech 99 L when MDF (Medium Density Fibreboard) is used as the machined material. The dynamometer Kistler 9257 B and DynoWare software is used for the measurement of forces and data analysis. The theoretical part of the thesis relates to the characteristics of the CNC machine, tools, tool angles and the methods of cutting resistance. The experimental part provides the description of the experiment itself as well as the changes of cutting conditions during the experimental process when using certain tools. Moreover, it explains the procedure of data processing and shows its final results. The conclusion of the thesis evaluates the data of cutting forces and cutting resistance. These data are further compared based on the technology and the parameters.

This thesis dealt with strength and economic parameters of machine-sewn seams in current upholstery production. It is focused on the determination of the tensile strength of the bound seams and the influence of the decorative seams and the various types of lining on it. In the economic part of the test, material and time consumption is measured. The result is the evaluation of the different types of seams and lining and taxation in connection with the consumption of time, materials and their cost.

Master's thesis deals with possibility of simplifying calculation hydraulic machines by converting the three-dimensional geometry in the plane. The aim is to create modifications of a trailng edge and determine their effect of the hydraulic parameterso of the machine.

The master thesis is focused on design of semi-professional sewing machine regarding tailor’s needs. The goal of this master thesis is to bring a new ergonomic solution with attractive styling. The sewing machine would be connected with table as one unit.

The master thesis deals with the construction and design of a high-speed synchronous machine with an outer rotor. The thesis is organised into three main chapters. The first chapter deals with machine design theory as well as mechanical limits, which are significant for high speed machines. This chapter also provides examples of applications of these electrical machines. In the second chapter, the initial design of the machine is calculated analytically. This machine design is optimised and the third chapter of this work shows the results of simulations using the finite elements method, including the evaluation of these results.

Tato diplomová práce pojednává o možnostech simulace a modelování elektrických pohonů na základě Bondových grafů. Je zde uvedena základní teorie k problematice. V práci jsou představeny modely stejnosměrného a synchronního stroje sestavené touto technikou. Dále je zde seznámení s Freeware knihovnou Bondových grafů BG V2.1 k programu MATLABSimulink. Za pomocí této knihovny byly sestaveny oba modely strojů. V poslední kapitole je uvedeno srovnání modelování na základě teorie Bondových grafů s modelováním v blokových diagramech.

The aim of my diploma thesis is to design a construction of a mechanical fine rack cleaner machine including an appropriate design of gear mechanism and its attachment to the frame. The cleaner machine is located in the inflow system of a turbine in front of the object of small hydro power station. The design of the construction of the cleaner machine will be based on a drawing documentation and a report with needed analytic and FEM calculations.
