The process of city block modeling using a procedural programming language
Koucká, Lucie ; Štych, Přemysl (advisor) ; Brůha, Lukáš (referee)
The master thesis deals with a block subdivision into parcels using procedural modeling. The main goal focuses on improving of the existing method called OBB-based Subdivision that uses auxiliary envelopes of rectangle shape for splitting. It is required to adapt the method to Czech conditions as well. The first part focuses on the analysis of scientific publications, which describes the development and current situation of procedural modeling issues. Then the methodology of suggested algorithm is described that tests a change of the envelope to the trapezium shape, respectively to the quadrangle shape. In conclusion, the proposed algorithms are tested on the real data in CityEngine, which offered the possibility of using procedural approach to automatically generate 3D parcels. The whole process is controlled by the limitations of development plans of the selected urban areas. Powered by TCPDF (www.tcpdf.org)

3D Reconstruction of extinct parts in the Dobříš town
Koucká, Lucie ; Štych, Přemysl (advisor) ; Oršulák, Tomáš (referee)
The main object of this thesis is the reconstruction and visualization of multidimensional model with using geographic information systems. The thesis deals with issues associated with the above mentioned topic as well. The 3D reconstruction relates to the Mírové square in the Dobříš town, which was affected by the redevelopment in the second half of the 20th century. During creating the 3D model, there was an endeavour to capture the best appearence of the area before this change. The reconstruction, created mainly by ArcScene, was made by using historical photos, aerial photographs and other data. Two softwares are tested and compared during modelling of 3D buildings - Bentley Microstation and Google SketchUp. Fly-by animations and pictures are the thesis results, being confronted with historical photographs.

Are Czechs superstitious or the effect of Friday the 13th in accidents on Czech highways
Koucká, Lucie ; Hronza, Martin (advisor) ; Rod, Aleš (referee)
The aim of this thesis is to find out whether Friday the thirteenth as a chosen representative of the superstition has an influence to the number of traffic accidents in the Czech Republic. The hypothesis that is being verified is that on Friday the thirteenth, drivers will be more cautious resulting in less accidents. Based on the five year long time series the model is estimated using the ordinary least squares with robust standard errors where the endogenous variable is daily number of car accidents. The exogenous variables are Friday the thirteenth, the public holidays, the precipitation, the average daily temperatures and the gas prices. The "Friday the thirteenth" variable turned out as statistically non-significant. Based on the results of the econometric analysis we can reject the hypothesis of this thesis. This conclusion was further confirmed by the results of the survey conducted.
