Increasing Single Cylinder SI Two-Stroke Engine Performance
Stejskal, Miroslav ; Drápal, Lubomír (referee) ; Svída, David (advisor)
This thesis deals with two-stroke engine design modifications to enhance its performance parameters. The introduction summarizes the various solutions of two-stroke engines. The next part deals with design modifications of the engine power, their implementation and subsequent modification. The work includes strain and stress analysis of the piston, which includes a complete indication of pressures in two-stroke engine. The achieved results of FEM analysis were used to design better piston geometry.

Cylinder unit of motocycle two-stroke engine
Stejskal, Miroslav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Miroslav STEJSKAL Cylinder unit of motorcycle two-stroke engine In the beginning is briefly described two-stroke engine features. Furthermore, according to the set of basic geometric and thermodynamic parameters, the maximum pressure in the cylinder during one engine cycle. For the selected operating modes are carried out strength tests of the upper piston and connecting rod eye. In conclusion, the results are evaluated.

Effect of tillage minimalization technology to control weeds in cereal crops
STEJSKAL, Martin
This diplom thesis deals with the evaluation of quality machines work for soil cultivation used in minimalization soil cultivation technology and weed control in cereal crops. The machines were evaluated for incorporation of harvest residues, uniformity of depth and size of lumps. It was further performed an economic evaluation of selected cost per operation soil cultivation. In order to monitor the development of weeds was based small-plot experiment, where was monitored representation of individual weed species and the effectiveness of selected herbicide.

Internal Organizational Communication Analysis
Stejskal, Michal ; Střížová, Vlasta (advisor) ; Procháček, Jan (referee)
The thesis deals with topics of internal communication with focus on its application in three particular companies. The main objective was to describe and evaluate the quality of internal communication, to analyze it and draw useful conclusions and practical recommendations to improve its efficiency. The basic concepts and specifics of information, communication, corporate culture and internal communication are presented and explained in the theoretical part, followed by an overview of the functions, goals, information flows and means of communication within the company. The assumptions of effective internal communication and related problems are accentuated. The practical part includes internal communication analysis based on a survey, qualitative interviews with managers, and company information available to the public. The thesis results in a detailed analysis of particular companies, their comparison, and specific recommendations for removal of the deficiencies and effective improvements.

Dynamics of Earth gases emissions in Czechia
Kroufek, J. ; Stejskal, M. ; Šebor, G. ; Mrlina, Jan ; Tesař, J. ; Suchý, V. ; Zeman, A.
A monitoring of the Earth gases emissions was carried out at selected sites in Cechia. Particularly, methan, CO2, SO2, Rn a H2S were investigated. It was proved that neither the chemical composition, nor the emissions themselves can be considered as permanent. They may be affected by geological processes including earthquakes, as well as by man-made activities.

Information and communication in the management of the music club
Stejskal, Michal ; Střížová, Vlasta (advisor) ; Švarcová, Eva (referee)
This work focuses on analysis of operation of the PopoCafePetl music club and on solution of existing problems of processes. Work is formally divided in two parts -- theoretical and practical. The first part introduces two very important managerial tools -- information and cummunication. Basic attitudes to the definition of the term information are discussed from the point of view of the disciplines examining it. A compendium of the communication forms, functions, and processes is enlisted with stress on the business communication. A structural proposal of information system fitted to the music club operation and management support was created in the empirical part of the study. Its realization and consequent implementation would simplify its run and service into a more efficient way. More economical management, more consistent promotion and the raise of its competitivnes should be their collateral product. To apply the conclusions of the analyses or information system itself would be convenient to any eterprise in this field of business.
