Revealed preferences for outdoor recreation in natural areas - Czech and European perspective
Kaprová, Kateřina ; Melichar, Jan (advisor) ; Brůha, Jan (referee) ; Šauer, Petr (referee)
K. Kaprová (2019): Revealed preferences for outdoor recreation in natural areas - Czech and European perspective Abstract of the Doctoral Dissertation The dissertation thesis focuses on the investigation and synthesis of recreation welfare benefits associated with natural areas in the Czech Republic and in Europe. The dissertation thesis consists of five case studies. These represent various geographic levels of analysis: the level of one single recreation locality, the national level that takes into account large natural recreation sites in the Czech Republic (including protected areas), and a synthesis of results of studies on the European level. The methodological approach is based on the theory of environmental economics and employs non-market valuation techniques based on methods of revealed preferences, namely the hedonic pricing method and two types of travel cost modelling. In Study I, we examine how the presence and characteristics of urban greenery affect property prices in Prague. The results confirm that proximity to greenery and its area are important determinants of housing prices in Prague, which means that residents realize the positive values provided by urban greenery, including recreational ecosystem service. Benefits to residents differ with the type of greenery. Urban forests have the...

Gel infusion screen system for additional waterproofing of various types of masonry with share of secondary raw materials
Melichar, Jindřich ; Klečka,, Tomáš (referee) ; Dohnálek,, Pavel (referee) ; Novotný, Miloslav (referee) ; Drochytka, Rostislav (advisor)
Virtually any construction project in our climate zone is facing some form of moisture. Older and historical buildings are mostly affected by the negative impact of water. Previously, the additional reduction of the moisture was executed only by mechanical methods, pushing insulating sheets or breaking through and cutting of masonry. Over time chemical methods were also invented, which are compared to the mechanical considerably simpler and user friendly applications to statics of treated buildings, making them ideal for the treatment of historical buildings or buildings that would not bear significant disruption. The main principle of chemical methods of redevelopment of wet masonry is the application of special material into the line of drilled holes with a given pitch. Subsequent penetration of the grouting material is believed to intersect an arc of individual drill holes, and thus to create so-called grout curtain that prevents the accumulation of water above it. Injection material may also contain a proportion of secondary raw materials, thereby reducing the influence of the impact of production on the environment. Efficiency infusion materials in masonry affected by many factors, such as temperature, humidity, or the type of material treated. It is also an important factor to determine the effectiveness of the remediation of the material, proving its ability to penetrate the building material by identifying its presence in it.

Tourism and mechanism of its monitoring in Czechia
Ducháčková, Jana ; Melichar, Jan (advisor) ; Čermák, Daniel (referee)
The objective of this master's thesis is to examine a detailed summary of the present situation of visitor monitoring methods in large-scale protected areas in Czechia. Methods used in Czechia are introduced on 9 areas. The main research tools used were interviews with 8 key actors and a survey with the head managers of 4 national parks and 25 protected areas. The questionnaire survey was conducted in November and December 2011 and had 100 % return. This thesis presents comprehensive characteristics of the situation in Czechia including levels of monitoring methods. It seems that this study is the first of its kind which has been done in Czechia. Findings show that there is systematic quantitative visitor monitoring in Czech national parks, but that there is not in protected landscape areas. The majority of national park and protected area management do not have a standard certificated methodology for managing counting visitors. This means that their results cannot be compared. To promote better understanding of methods the text includes 22 examples of visitor counting done in chosen European countries and 9 examples from other non-European countries with the goal of summarizing which methods and technologies are available and suitable for use in Czechia. Finally, the evaluations of eight...

Travel Cost Analysis in Recreation Demand Models.
Schlehr, Miroslav ; Melichar, Jan (advisor) ; Vojáček, Ondřej (referee)
This work analyses the difference between perceived and computed travel cost data in Recreation Demand Models. Travel cost in this study includes only the cost which stems from the distance which the visitor had to overcome in order to get to recreation site. This study has examined the use of vector model in Geographical Information System as a source for computed data. Three different approaches of calculating travel costs were analysed in single-site model of recreation model. This work also focuses on current composition of travel cost in Travel Cost Method, describes the constraints of this method and consequences for further research.

Combining carbon sequestration and biodiversity conservation : possible way to protect rain forests
Baďura, Tomáš ; Ščasný, Milan (referee) ; Melichar, Jan (advisor)
Despite the fact that forests and rain forests in particular are known for being a source of various goods and services tropical deforestation, mostly happening in developing countries, is still way over the sustainable rate. Nevertheless, due to the massive potential in reducing carbon emissions from deforestation and its importance in biodiversity conservation, rain forest are increasingly expected to play an important role in both conservation and climate change mitigation activities. Moreover, it might be possible to combine both these ecosystems services together in a synergistic way which would benefit each other. This paper will examine these issues, especially from the biodiversity conservation perspective.

Comparison of height and jumper parameters for young girl volleyball players in 2002-2009
Melichar, Jan ; Buchtel, Jaroslav (referee) ; Vorálek, Rostislav (advisor)
Thesis title: Comparison of height and jumper parameters for young girl volleyball players in 2002 - 2009 Thesis aim: Based on the results obtained in the test tournaments in 2002 - 2009 (Kafka's memorial) create order 15-best placed volleyball players, under-reach at strike jump with rozbehem(heat?). The results compare for each yer, according to the selected somatic assumptions (body height, the range from the floor stretched arms) and selected performance assumptions (net reach - absolute jump, reach at strikejump with heat). Method: For my thesis examination I have looked up and processed results of standardized volleyball tests. Each year these tests are applied to the players at the regional youth centre championships. Nowadays these tests are rather applied to selections of the best regional players. Concerning girl players it refers to ,,the Memorial of Milan Kafka". The testing is provided by the organizer in coordination with commissioned co-workers of youth committee and youth coordinator. For processing and evaluating of the acquired data I have used the following mathematical-statistic methods: arithmetic mean, variation range and decisive anomaly. Results: I have transformed the final tests results into transparent graphs through which you can see apparent differences between...

The Pump with a Diffuser with Stochastic Blades (Runner and Diffuser)
Dobšáková, Lenka ; Melichar, Jan (referee) ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This doctoral thesis studies the non-uniform blade cascade for centrifugal pumps. Influence of non-uniform blade cascade is investigated on the impeller and diffuser. A non-uniform blading impeller of pumps in this doctoral thesis was examined in terms of influence on efficiency characteristic. The idea of using non-uniform blading is to obtain a flat efficiency characteristic. Then the centrifugal pump could be used on larger scale of power with achieving a sufficiently high efficiency. The work is based on experimental measurements and numerical simulations of non-uniform hydraulic pump components. Non-uniform impeller and the diffuser were newly designed for this research. A new measuring track of small submersible pumps was needed to design and build for measurements. Different pump combinations with conventional hydraulics on one working point and hydraulics with non-uniform were measured. All measurements were evaluated and characteristics of efficiency, head and power were obtained for each measured combination. Some of pump combinations (which were measured in experiment) were numerically simulated by program Ansys Fluent. Data needed to evaluate the characteristic of efficiency and specific energy were collected from each numerical simulation. A theoretical consideration concerns the influence of non-uniform blade cascade applied on diffuser. The suggestion how to decrease hydraulic losses in canals was done. The theoretical consideration how to make a flat efficiency characteristic was made.

Possibilities of screed application on oily or wet concrete
Holomčík, Zdeněk ; Melichar, Jindřich (referee) ; Drochytka, Rostislav (advisor)
This thesis studiest he track floor system, the interaction of adhesive bonding compound with a underlaying concrete, which will be contaminated by moisture and oil. For such contaminated surface was designed polymer-cement concrete, which were subsequently tested its properties, in order to determine whether it achieves the required strength of 80 MPa uniaxial compressive and whether it can be applied to wet or oily underlaying concrete. From the results we can say that the newly proposed system achieves the specified requirements and could be applied to damp and oily surfaces.

Testing of Indicators for Technical Analysis in Stock Market Trading
Melichar, Josef ; Žák, Jakub (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with testing indicators of technical analysis and their behavior with different kinds of market. In this thesis we tested simple moving averages, exponential moving averages, relative strength index indicator, MACD indicator, and stochastic indicator. At the end we tested a combined indicator, and that was stochastic with MACD. We created an automatic trading system for each of these indicators. From the results we can find out, that by optimizing the technical indicators we can get satisfying results by increasing the profitability. Indicators that seemed non-profitable were in fact profitable after the optimization. However testing parameters of indicators of technical analysis alone is not enough to make a stable profit.
