Insulation influence on heat consumption
Gregor, Jiří ; Bokišová, Lenka (referee) ; Hejčík, Jiří (advisor)
The aim of this bachelor thesis is to analyzethe energy budget of a house before and after heat cladding and to assess whether the heat cladding is perspective, if the invested money returns and to show the main advantages and disadvantages of cladding. Measured values from 1992 to 2012 are used in this thesis. Heat cladding in our house was done at the turn of 2003-2004 and in the same yearsthe old wood windows were replaced with new plastic ones.

Secondary raw materials production from municipal waste
Kouřil, Čeněk ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
The main purpose of the bachelor thesis is to give an overview of the current system of municipal waste management and to demonstrate its techno-economical demands. To solve these objectives, an analysis of the current state in Czech Republic was carried out and a calculation tool was created to evaluate the overall techno-economical balance of the management system at the regional level. The results of the tool showed that it is expensive for municipalities to carry out waste management activities and would not be feasible without complex subsidies. The reader gets a basic overview of the current waste management system in Czech Republic and acquires knowledge of its partial techno-economical costs.

Effective proposal and operation of recycling line as an element in waste management
Dufka, Martin ; Janošťák, František (referee) ; Gregor, Jiří (advisor)
This master thesis deals with the current situation of waste management of material usable municipal waste with focus on various fractions of plastics. The theoretical part summarises the legislation of waste treatment, also contains an analysis of the current situation of waste management in the Czech Republic and comparison the situation in the European Union. In the next part of thesis are described basic fractions of plastics and their properties. There are mentioned the current problems with plastics processing and the risks of leakage to the environment. Furthermore, a complex chain of plastic waste reprocessing is described, since the inception of plastics waste to the manufacture of products made from recycled plastics. The most attention is paid to the discription of recycling plant, where the output material from sorting lines is reprocessed into a secondary material in the form of flakes or granules. Also this part is focused on the technology of recycling line and the individual devices are described. In the practical part of the thesis is created techno-economic model of recycling line with the aim of its use for balance calculations of recycling and also economic evaluation. As a part of the model was made a market research of secondary raw materials with a focus on price development. Subsequetly, sensitivity analyzes of selected parameters are applied to the model and the impact of scenarios on the economic results are evaluated.

Advanced Logistic Models for Waste Management
Gregor, Jiří ; Jegla, Zdeněk (referee) ; Pospíšil,, Karel (referee) ; Stehlík, Petr (advisor)
The purpose of the dissertation thesis is to prepare transport techno-economic models which will be able to estimate the transportation cost for selected scenarios. The main goal is to describe the complex transport chains in waste management, using different types of transportation (road, rail) and transport different types of waste. The key element of preparing techno-economic models is the identification of input parameters which are important for estimating the cost of transport. At the same time, it is necessary to correctly identify the processing facilities that will be part of complex transport chains. The total outputs will be presented in the form of a feasibility study.

Regional Characteristics of Municipal Waste
Švarc, Vít ; Gregor, Jiří (referee) ; Kropáč, Jiří (advisor)
This thesis describes the current state of waste management in Czech Republic and assesses the impact of small businesses on the production of municipal waste in various Czech regions. The main objective of this thesis is to create a model of production of municipal waste with a focus on so-called commercial waste or an industrial waste, which is part of the waste, produced from municipal waste management systems. The work is based on statistical data of municipal waste production, statistics on the representation of small-scale industries of the Czech municipalities, and uses correlative and regressive analyses.

Transportation systems in waste management
Koutná, Marie ; Pavlas, Martin (referee) ; Gregor, Jiří (advisor)
The aim of the thesis is to elaborate on transport systems in waste management as they represent a key part of the waste management process. Its theoretical part covers legislation in waste management and sorts and systems of household waste collection. In the practical part there are commercially used vehicles chosen out and the fixed costs of their operation determined. Based on operation data, average velocities in an out of urban areas are calculated. As an outcome of a waste transport prices software, the influence of transport distance and waste mass are described, taking the average velocities into account.

Rail transport in practice
Poul, David ; Pluskal, Jaroslav (referee) ; Gregor, Jiří (advisor)
The diploma thesis deals with railway transport describes its role in combined transport and compare key aspects with road transport. As part of the diploma thesis, a detailed database of railway tracks in the Czech Republic was created, on which the route planner was built with the possibility of setting waypoints. The route planner also includes the implementation of exclusion activities. A comprehensive technical-economic model of railway transport was created with four calculation models and detailed investment planning, thanks to which is possible to assess whether the purchase or lease of train sets is more advantageous when making investment decisions. Furthermore, a technical-economic model for the branch line was created. The last section deals with the created transport model for the catchment area for 8 localities and 5 types of transported waste/commodities. The transport model was used to evaluate two selected areas – the South Moravian Region and Kolín.

Construction of boom of loader Dapper
Gregor, Jiří ; Petráš, Jiří (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the analysis of the current kinematic mechanism of the DAPPER 5000 boom. The second part of the thesis deals with the new mechanism design. The new solution is also analysed kinematically and forcefully. The first part of the thesis is devoted to a description of the DAPPER 5000 and its parts. It is followed by a description of its boom, its analysis and comparison with the booms of competitive loaders. After a critical review of the various boom concepts, where their suitability for the DAPPER 5000 is assessed, a new mechanism for the DAPPER boom is designed. This is followed by a detailed analysis of this mechanism, a basic strength check and, in conclusion, the results of the analyses are summarized, and the meaningfulness of this structural change is evaluated.

Emerging systems of collection in waste management
Petrasová, Zuzana ; Kropáč, Jiří (referee) ; Gregor, Jiří (advisor)
The main aim of the thesis is a description of the methods used in the collection of waste with a focus on non-traditional ways. Its part is the outline of a basic technical specification of the methods. The analysis is further used to determine the technical-economic model for underground waste containers, which is able to calculate the construction costs based on given values. The model is designed for containers of three different volumes and is the main result of the thesis. The knowledge of input investments is being used to compare the economic demand and the potential return of investments with regards to the traditional collecting methods (bins, containers) and the pneumatic underground system, whose estimated costs are taken from foreign models.
