Analysis of influence of a roof construction on indoor thermal stability in summer season
Hofman, Petr ; Katunský,, Dušan (referee) ; Hirš, Jiří (referee) ; Mohelníková, Jitka (advisor)
The design of the building must respect the basic conditions for ensuring thermal comfort in the living space. The thermal comfort is influenced by several factors and one of them are the constructions of the building envelope. This work was focused on investigating influence of roof structures. The goal was to make analysis of influencing the selected modifications of the roof compositions to the thermal stability in the summer formed by experiments and detailed computer simulations. On the basis of these findings were defined suitable modifications. It has been worked out that the maximum indoor air temperature can be reduced by up to 1.5 °C in a suitable way. The cool roofs, thermal inertia and the ventilated air cavity layer have the greatest benefit. When evaluating the return on investment in a roof with high thermal inertia represented by a concrete layer of 100 mm, its return compared to a light roof and airconditioning is 12.1 years. The return on installation of external blinds on roof windows is 3.3 years compared to airconditioning.
Analysis and optimalization of the accessibility of emergency services in the CR using GIS tools
Paraj, Zsolt ; Štych, Přemysl (advisor) ; Hofman, Petr (referee)
The bachelor's thesis deals with modeling the current situation of Emergency medical services in the Czech Republic in terms of surface area coverage and accessibility of the ground rescue units. Also the subject of the project is to suggest improvements in distribution of outpost of Emergency medical services after the changes in act of emergency medical services, which newly declares the arriving time to 20 minutes. The project was developed in ArcGIS 10. The basic hypothesis of a lower number of ambulance outposts after optimization was confirmed, but the assumption, that emergency medical services have reserves for worse traffic situations, was partly refuted.

The analysis of Tokyo railway accessibility in Japan by using GIS
Pokorný, Tomáš ; Hudeček, Tomáš (advisor) ; Hofman, Petr (referee)
This work is about accessibility of Tokyo-eki (東京駅 Tokyo Station) by using main railways of Japan Railways Group (JR グループ Jeiaru Gurupu). The introduction is giving main ideas about the subject such as research of accessibility. Continuing with categories of train connections and historical facts in Japan and Czech Republic. Special part is talking about transcriptions from Japanese to Latin. Main part of work is description of time accessibility model. Data were searched on specific multilingual sources. Next part is comparing Czech and Japanese accessibility by using anamorphosis model. In the conclusion is commented confrontation of regional accessibility in Japan and Czech Republic according to the maps. Keywords: time accessibility, railways, network analysis, Japan, Tokyo
ASSESSMENT OF PHOTOVOLTAIC POTENTIAL OF ROOFS IN PRAGUE AREA
Klouček, Tomáš ; Štych, Přemysl (advisor) ; Hofman, Petr (referee)
Assessment of photovoltaic potential of roofs in Prague area Abstract The main aim of thesis is creation of algorithm for determination photovoltaic potential roofs of buildings using the basic tools of ArcGIS software for the knowledge a digital surface model and vector layer of built-up area. Possible electrical power and return of investment is also calculated for better assess of the suitability location. The sequence is inserted for easily using into ModelBuilder tools. The functionality of the model is verified by applications in Prague 8, Karlín and it is visualized in several maps. In addition there is a briefly summarized introduction to photovoltaic and possibilities of using GIS in this field in this thesis. Keywords: Photovoltaic, GIS, Digital surface mode
Generation gap in the attitudes towards religion in contemporary Japan
Hofman, Petr ; Sýkora, Jan (advisor) ; Labus, David (referee)
This bachelor thesis focuses on generation gap in the attitudes towards religion in contemporary Japan. Beginning from perception of belief or religious activities. First part is focused on methodological and theoretical part, which originates in sociology of religion. Western influence is applicated into the Japanese environment. There are also defined concepts of multiple meaning used in this work. Syncretism and secularization in particular. Second part is mainly focused on differences between generation X and Z. Third part belongs to practical comparison, which is supported by sociological questionnaire oriented on Japanese young generation. Keywords Japan, sociology of religion, generation gap, secularization, syncretism
Building modeling from airborne laser scanning point clouds of low density
Hofman, Petr ; Potůčková, Markéta (advisor) ; Šíma, Jiří (referee)
A Laser scanning is a relatively recent remote sensing method which nevertheless quickly gained a prominent position, especially in the area of building detection and 3D modeling. Methods for building detection and 3D modeling initially used model-driven approaches which compare a laser scanning point cloud to a set of predefined building models. A method for determining building roof types using such approaches was presented in the article of Hofman, Potůčková (2012). An important advantage of model-driven approaches is their relative robustness to various data deficiencies such as low point density or low spatial accuracy. However, output of such methods is limited to a predefined set of building models and does not allow for diversity of actual buildings. For this reason, approaches used almost exclusively nowadays are data-driven. These methods search in datasets for a set of primitives (mostly roof planes) that are subsequently used to form the final model. This approach benefits from universality of resulting models but requires generally high data quality, especially in respect to input point cloud densities. The study of Hofman, Potůčková (2017) presented a data-driven method that can reliably detect buildings even in a very sparse point cloud in spite of using data-driven approach. At a density of...

Apartment building, Šlapanice
Palásková, Zita ; Hofman, Petr (referee) ; Müller, Jan (advisor)
The subject of the bachelor thesis is the design of the new apartment building in Šlapanice. The building is situated on the outskirts of the town, on a unbuild plot. The apartment building is designed partly with basement with four ground floors and has 12 residential units. The entrance to the building is from the north side. The construction is based on strip foundation. The construction system is a wall longitudinal from the Velox permanent formwork system. The ceiling structures are also designed from the Velox. The roof of the building is warm flat with vegetation layer.
Apartment building, Prievidza
Kyška, Roman ; Hofman, Petr (referee) ; Müller, Jan (advisor)
This bachelor thesis deals with the design of the apartment building. The building is located in a slightly sloping terrene in the cadastral area of Prievidza. The footprint of the building is mainly rectangular in shape with jumped parts of the facade. This is a udergroud object from the half part under the terrene with three above-ground floors. The apartment building has a total of seven apartments and a basement is used for commercial use in the hairdressing services. The remaining part consists mostly of storage and technical rooms. The KMB SENDWIX M structure is used as the construction of the perimeter walls, which consists of the main supporting structure made of sand-lime bricks and the thermal insulating layer of the contact insulation from the stone wool system. The ceiling construction is used from filigree ceiling panels and a single-skin flat roof with a 3% inclination is used to cover the building. The work contains project documentation for building realizations.
