The aim of this thesis is to introduce the proposal of the technological line (from the initial intake of the essential raw material to the final product) for the production of pellets from biomass. For better understanding, this work presents the characteristics of various types of biomass and its most common use in everyday life with the focus on specific kinds of pellets (standards, certificates, protective marks both Czech and foreign). Further it informs about the issue of classification, quality frameworks and specification of solid biomass for energy purposes and characteristics associated with the legislation, technologies, techniques and legislative conditions of use of waste biomass. It also compares the different types of pellet samples in the relation to the most important aspects (contents of substances, ash, calorific value etc.) and in what price range they appear in our market. Subsequently, on this basis, the assessment of the technical and economic aspects of the proposed solutions is carried out and the major physical chemical features of biomass are described.

This thesis is focused on the maitenance of the Green vegetation on the higway, specialy for the central reserve median of these communications. The main theme of this thesis are mechanical lines used for these works necassary and financial cost of the mechanical lines. Mechanical lines for the Green vegetation maitenance are analyzed at the way of its work, the technique used and techniques position in the mechanical line. The next part of the thesis is devoted to an analysis of the finacial cost for work of the mechanical lines. Informations used for the calculations were obtained from the statemnets of the operating mechanical lines on the higway D2 at administration SSÚD 7 Podivín.

This thesis gives a description of technique utilization forage and methods about forage preservation. Next part presents the factors and opportunity of organization machinery to the machine line for ensilage. Practical part compares results of practical field experiment about self propelled harvester and various transport vehicles for transport cutter forage. The experiment monitored fuel consumption, engine hours, turnover time and transporting amount of vehicles which are then compared.

This diploma thesis comes out of legislative requirements for a decrease in the quantity of biologically decomposable communal waste put in disposal sites and the support of composting. The thesis is focused primarily on making a draft of gathering and collecting biologically decomposable waste, its processing by composting and a draft project on a composting plant in the conditions of Adamov city. The plan of the whole system was set on the basis of the specification of the source of biologically decomposable communal waste and its weight flow depending on the type of a built-up area, evaluation of contemporary used technologies of composting with regard to the quantity of processed waste.

This thesis deals with the problematics of varnish degradation due to maintanance of a car or more precisely due to washing of a car bodywork and searching for a gentle washing of a car. The first section of this thesis discusses the creation of a protection layer of the car bodywork or types of varnishing, particular layers of varnish and additional products enhancing the qualities of car varnish. Second part of thesis analyses the measuring and evaluation of the state of varnish layers and uses the results for valuation of estetical and functional advantages and disadvantages. In third part we deal with description and categorisation of types and technologies of car washing. Fourth part focuses on experimentation and comparison of varnish degradation due to selected types of car washing using tests simulating real conditions of regular service. Particularly we evaluate portal washing units and hand washing. Consequently we subjectively and objectively analyse all the information and finaly we project this information to time and economical perspective.

This thesis is going into matters of saving energy and more general cost reduction processing with preoccupation on pneumatic systems. In the research part are the abstracts of legislative and normative regulations. They relate to the sphere and an analysis of the possible causes of increased operating costs. The practical part of thesis is preoccupation on the analysis of the selected machine lines. Analysis spans monitoring and measuring the energy heftiness of pneumatic system and all of its related parts. Based on the results of the analysis, defined by the potential energy saving and proposed ways to minimize them, the amount of necessary investment capital and payback time can be calculated. Part of the conclusion of the thesis is evaluating proposed solutions and knowledge-based recommendations are formulated to reduction of energy heftiness of pneumatic systems.
