Návštěvnost v Krkonošském národním parku – ochota platit za kulturní ekosystémové služby a vliv pandemie Covid-19 na návštěvnost v parku
Krejčí, Tomáš
The thesis deals with the topic of willingness to pay for ecosystem services in the Krkonoše Mountains National Park. It also examines the impact of COVID measures on visitor numbers in this National Park. The aim of the thesis was to determine the potential willingness of visitors to the Krkonoše Mountains National Park to pay for entrance. A secondary aim of the thesis was to evaluate the effect of the Covid-19 measures on visitor numbers based on data from census facilities located in the National Park. A literature search method was used in the thesis to clarify the concept of ecosystem services, their valuation and payment for them, including the willingness-to-pay method. Quantitative research was used to fulfill the objective of the thesis in which data was collected from a questionnaire survey. The data was then compiled into contingency tables and interpreted using graphical displays. The most common amount that visitors are willing to pay to enter the National Park was found to be 50 CZK. Data from the census facilities showed that anti-Covid-19 measures that somehow restrict the movement of people have a negative effect on visitor numbers in the National Park.

Polycentric urban forms: The relevance of scale for metropolitan and city planning
Malý, Jiří ; Krejčí, Tomáš
The paper deals with the importance of scale in metropolitan and urban planning, in connection with the promoted and often applied concept of polycentric development. Although the normative conceptualization of polycentricity to some extent reflects the multi-scalar dimension, the operationalization of the concept encounters a number of limitations and fuzzy meanings that result from different scales of analysis and interpretation. Using the Czech context of planning practice, the negligence of the importance of overlapping geographical scales and limits of binding spatial planning materials is documented. The dependence of polycentricity on the scale has consequences both for the analytical evaluation of the spatial situation of the settlement system and for the subsequent interpretation of the results and the setting of further development strategies.\n

Monitoring zatížení krajiny Krkonošského národního parku účastníky cestovního ruchu
Krejčí, Tomáš
The thesis deals with the problem of strain on nature caused by tourism participants, and the possibilities of their monitoring. Included inside are possible options lessening said strain, which are compared with measures used in national parks. The goal of the thesis is to evaluate data collected by 27 addition devices which are located within Krkonoše Mountains National Park, and with the help of this data, identify key points of tourist attention, and by extension places most strained by visitors. To reach the mentioned goals, the method of literary research was used, thanks to which terms crucial for the thesis were clarified, and with the help of elementary time series analysis, places with the most strain had been identified. The most strained, and also most visited, turned out to be places on the summit parts of the national park. According to addition devices, the most visited place appeared to be the highest mountain of the Czech republic, Sněžka. After that, it is Luční bouda, Labská bouda, and near from there, the spring of the river Labe.

This master thesis deals with the current situation of medical waste management in the Czech Republic and available medical waste treatment methods. The first part summarises the legislation of waste treatment and contains an analysis of the current situation of medical waste management in the Czech Republic and comparison to the situation in the European Union. The second part describes medical waste treatment methods and following technologies for energy utilization when thermal treatment method is applied. In the main part of this thesis, a complex medical waste-to-energy system in a model region is designed according to the input data. The design includes description of the collecting and transportation system of the waste, capacity of the unit and suitable thermal treatment and heat utilization technology choice. A calculation model is created for the proposed unit and based on this model, an analysis on energy utilization effectivity is made. As a result of the thesis, environmental, technical and economical assessment is created based on the estimation of the investment and operating costs.

Up-to-date off gas cleaning system for Medical Waste-to-Energy units
Kotas, Dan ; Krňávek, Martin (referee) ; Krejčí, Tomáš (advisor)
This master's thesis deals with current situation of medical waste management in the Czech Republic and it also analyzes the quality of existing units for thermal treatment of the medical waste. In the second part of the thesis, available off-gas cleaning methods were described as well as the emission limits for waste incineration, which correspond to the legislative regulations effective in the Czech Republic. These emission limits are considered as input data for off-gas cleaning system design. In the main part of this thesis, two technological solutions of off-gas cleaning methods for Up-to-Date medical waste incineration unit were designed. The unit is designed for energy utilization of 1400 tons of medical waste accumulated during one year in a regional hospital of model region. From given input parameters, two appropriate apparatus concepts were created. After that, both concepts were evaluated either form energetic point of view as well as from material one. From these evaluations, key apparatuses of both concepts were designed which provided necessary design dimensions for further investment price estimation of each individual key apparatus. In the conclusion of this thesis, the best solution of an off-gas cleaning method was picked according to the comparison of operating and investment costs.

Community area risk assessment for flash flood
Kolejka, Jaromír ; Rapant, P. ; Krejčí, Tomáš
The flash floods forecasting is struggling mainly with extraordinary irregularities in origin of causal precipitations. They only in conjunction with the territory water saturation caused by antecedent precipitations start effect of other local factors that can consequences of short-term extreme precipitation either worsen or mitigate vice versa. Other community area features represent a permanent potential for an adequate territory response after heavy rains. According to current knowledge, it is possible to assess the flash floods hazard of a particular territory in case of extreme precipitation in advance. If such precipitations are already on the ground, or if they are just coming up in the atmosphere, the local flood control headquarters has at least time enough to call alarm and issue a flood warning. In the ideal case, it is possible to incorporate such area assessment into the concept of decision-making of the disaster staff and to insert it into the master plan documentation. The aim of this text is to present above mentioned original method, which can be used in authomatic GIS environment by public administration as well as other users. Suggested procedure is based on automatic hydrologic modelling in ArcGIS platform in combination with advanced digital terrain model. Delimitation of partial catchment basins is also part of our proces, which enables to decide about the risk value of the area in more detail using weighted arithmetic mean. These methods result to detailed imagination about probably threatened localities - and it is essential tool for local authorities and their decision making process in case of early warning.

Lifelong localization of robots
Krejčí, Tomáš ; Barták, Roman (advisor) ; Obdržálek, David (referee)
This work presents a novel technique for lifelong localization of robots. It performs a tight fusion of GPS and Multi-State Constraint Kalman Filter, a visual-inertial odometry method for robot localization. It is shown in exper- iments that the proposed algorithm achieves better position accuracy than either GPS and Multi-State Constraint Kalman Filter alone. Additionally, the experiments demonstrate that the algorithm is able to reliably operate when the GPS signal is highly corrupted by noise or even in presence of substantial GPS outages. 1
