Design of City E-Bike
Růčka, Jakub ; Surman, Martin (referee) ; Křenek, Ladislav (advisor)
The traffic situation in cities is getting worse every day. The number of cars that its infrastructure cannot accommodate is constantly growing. The design of an urban electric bicycle was chosen as the topic for this thesis in order to analyse the problematic aspects of the product and the environment in which it is used and try to solve them. Therefore, the final design primarily respects the user and their needs. It meets the individual ergonomic and technical parameters. The refinement of the e-bike to the last detail improves comfort and safety during riding. Thanks to the appropriate integration of lighting elements directly into the individual parts of the e-bike, a sufficient amount of illumination has been achieved. The e-bike allows its user to use light signals while changing directions. A storage space has also been designed for the e-bike, which allows smaller items to be carried. This thesis brings a new perspective to the urban electric bicycle. It shows how its different parts can be approached and how to work with different practical accessories. It also outlines how an e-bike could be connected to a smartphone in order to make its use more pleasant for the user.

What do children draw (not only ) on the asphalt
Hnyková, Michaela ; Velíšek, Martin (advisor) ; Kafková, Helena (referee)
The topic of this thesis What do children draw (not only) on the asphalt is to explore a material potential of outside environment as a specific device for teaching art education. The first part defines the role of the arts in contemporary education system, sets out the main goals and points out specialties of the field. The next section deals with the observation of spontaneous creative expressions of children on non-traditional sourfaces, their place in the natural need for exploration, and playing as a means of understanding the world. Compares the difference of the creation in outdoor environments on unconventional surfaces and the classical indoor creation and deals with the potential use of this knowledge. Looks for possibilities which would enrich the teaching of art and offer teachers new inspiration. Finally, on the basis of my own interventions, verifies the applicability of theoretical findings and their possible application in teaching at primary schools.

Comparative Study of Variants Evaluating Noise in Urban Environment
Pomališová, Michaela ; Moldan, Bedřich (advisor) ; Řiháček, Tomáš (referee)
Noise currently represents a problem in society, which disturbs mainly inhabitants in populated areas. It decreases their quality of life and endangers their health. The sensitivity to noise is individual, yet it is possible to measure noise by various means and evaluate its intensity and impact on human beings. Noise as a part of the environment, is becoming on the basis of resident complaints a discussed matter on the town and city level. Their management of noise necessarily involves monitoring and taking subsequent precautions. This work deals with comparing objective and subjective methods in noise evaluation in urban environments and its impact on the quality of life and the health of the residents. It uses a method of the multicriterial evaluation of variant also known as the multicriterial analysis. It compares four approaches to evaluate noise; two objective involving measuring, one subjective using a survey method and one hybrid. The winning method represents the subjective evaluation, which has fulfilled given criteria and acquired a significance of 75 %. All variants included in the analysis are suitable for noise evaluation in outdoor environments on a local level. The outcome of this work is to recommend towns and cities in the Czech Republic to use the winning compromising variant,...

Runoff generation in urban environment
Píchal, Jan ; Daňhelka, Jan (advisor) ; Čekal, Radek (referee)
As the area of impervious surfaces at urban environment increases, the more rapid runoff and urban flash floods lead to frequent overflow of the sewer system. For storm water runoff prevention and mitigation, there are soakaways commonly built in newly build up areas. The soakaways volume calculation is given by ČSN 75 9010 regulation in the Czech Republic. The presented thesis verifies applicability of this regulation in selected study sites (smal basins) of projected building construction model basins, which differ with regard to their infiltration characteristics, slope, area and degree of planned urbanization. The runoff calculation was estimated by Clark's Unit Hydrograph (UH) transformation and triangular SCS UH. HEC-HMS software has been used for Clark's UH application. Triangular UH runoff calculation has been done using MS Excel environment to establish a series of equations and logical conditions. Both models' results were compared for storms with 5 years, 10 years, 100 years and theoretical maximum return period; thus also for storms with longer return period than is proposed in the regulation. The positive differences in soakaway peak overflows and peak runoffs in study sites before the start of the urbanization were compared and evaluated, together with the differences in soakaway...

Study of size-resolved atmospheric aerosol using cascade impactors
Kozáková, Jana ; Schwarz, Jaroslav (advisor) ; Vojtíšek, Michal (referee) ; Krejci, Radovan (referee)
This dissertation includes two main research projects: 1) the investigation of the intermodal fraction and 2) the influence of regional air pollution transport on Ostrava. Introduction and aim of the first project. Fine and coarse particulate matter (PM) of atmospheric aerosol are considered as separate pollutants and overlap in the particle size range of about 1 - 2.5 μm (aerodynamic diameter dae; PM1-2.5) which represents the intermodal fraction. Sources of both fine and coarse fractions contribute to PM1-2.5 to different extents due to changing meteorological and spatial conditions. Therefore, there is an ongoing discussion as to whether PM1 should be included for monitoring as an additional fine particulate pollutant by the ambient air quality standard. The intrusion of the one fraction to the other one can lead to some inaccuracies in the source apportionment, epidemiological and exposure studies. The aim of the first project was to examine the associations between PM1-2.5 and the coarse (PM2.5-10 or PM>2.5)/fine (PM1) fraction under different meteorological conditions at various sites in the Czech Republic during winter and summer seasons. Introduction and aim of the second project. The EU air quality standards have been frequently exceeded in one of the European air pollution hot spots:...

Ecological and ethological aspects of bird-building collisions
Semeráková, Anna ; Sedláček, Ondřej (advisor) ; Koleček, Jaroslav (referee)
Collisions with artificial structures represent one of the most significant cause of bird mortality worldwide. Accounting for hundreds of millions bird deaths each year, bird-building collisions represent a particular problem. Although the bird's vision system is perfectly adapted to the orientation during fast flight, birds are often confused due to the transparency or reflectivity of the glass. Moreover, light pollution of urban areas interferes with the physiological geomagnetic and polarized light compass in birds, which causes the night migrants to disorient. The bird-building collision frequency variates in time and space. Throughout the day, largest number of fatal collisions occurs during early morning. Throughout the year, the peak in the numbers of fatal strikes appears in the course of autumn migration. Local species abundance did not appear to be the most important predictor of collision probability. Species traits making birds highly prone to collisions are small body size, high flight speed, long distance of migration and feeding strategy requiring rare and temporary food sources. Aggressive males during the mating period and inexperienced post-fledging juveniles are among the most vulnerable individuals. Based on taxon-specific ecological traits, some bird families were identified to...

Legislativa a veřejné prostranství
Boušková, Linda
Legislation has an impact on the shape of cities, which of course include public spaces. Although public space is a generally known term, its definition is problematic in terms of Czech legislation. This article analyzes public space through the lens of Czech legislation and draws attention to its contradiction with another valid law. This article illustrates the interpretation of legislation, using the urban structure of the city of Brno as an example. This article will also speculate about its weaknesses.
