Effect of geographical location on solar systems performance
Kuljovský, Martin ; Weismanová, Júlia (referee) ; Jaroš, Michal (advisor)
The sharp price increase and the impending depletion of fossil fuels has led to an increasing interest in renewable resources. This thesis deals with one of the most lucrative substitution between renewable sources - the solar energy. The introduction describes the emergence and spread of energy in the universe, then is devoted to basic distribution of collectors and informs about the possibilities of their use. In particular, it contains formulas for calculating the basic performance characteristics and then comparing differences between panels. Finally, it compares the effectiveness of collectors for different geographical locations in the Czech Republic.

Position Tracking with GPS and PDA
Černohorský, Vilém ; Herout, Adam (referee) ; Szőke, Igor (advisor)
This work presents steps in creation of remote position tracking application. Document introduces history of geographical positioning and navigation, and describes development of navigation from primitive utilities to complex radio navigation systems. Global Positioning System is described in more detail including NMEA protocol used by GPS receivers. This work also presents several current navigation applications. Based on obtained information work presents analysis, object-oriented design and implementation of remote position tracking system.

Geolocation in Internet using latency measurements
Harth, Petr ; Balej, Jiří (referee) ; Komosný, Dan (advisor)
This diploma thesis is concerned with practical realization of CBG (Constraint-based Geolocation) algorithm, which is one of the IP (Internet Protocol) geolocation technique. IP geolocation determines the localization of a computer workstation location on the basis of on its IP address. The factors causing delays in data transfer are discussed first, followed by discussion of the issue of measuring these delays. The detailed explanation of IP geolocation follows where its contexts as well as the active geolocation techniques (techniques based on delay measurement mentioned above) are described. After that a brief description of PlanetLab experimental network, which was used for geolocation techniques measuring, is presented followed by a section explaining the creation of reference points and targets, which are another necessary prerequisite for practical realization of the method. Then the practical realization is explained in the form of CBGfinder program and its verification on the basis of artificial input data along with an actual example of IP geolocation of a point in the Internet are provided. Last but not least the measurement results of CBG algorithm are introduced, based on the analysis of Bestline parameters of one of the PlanetLab nodes measured in the period of one month, followed by a discussion of the inaccuracy of geological position and the computation speed. The cumulative distribution function as well as the kernel density estimation are also described. Final part of the thesis consists of discussion on measured results compared to results of other geological techniques results implemented by colleagues of the author of this diploma thesis. The results are compared on the basis of average inaccuracy of geological position estimations and its median, computation time, cumulative distribution function and kernel density estimation are also taken into regard.

Geolocation - Determining Locality from the IP Address
Zvonček, Radovan ; Plchot, Oldřich (referee) ; Herout, Adam (advisor)
Geolocation is a process which tries to determine geographical location of a device connected to the internet. Location can be represented by exact coordinates or by description of country, region and city, which is what this thesis is focused on. First, it explains the concept of geolocation and introduces available solutions. Next, it describes the design and implementation of own solution on the basis of gathered information. Solution is tested on two sets of IP addresses. Gathered results are relatively correct when determining countries, but contain inaccuracies when determining cities.

Jihlava ? location, structure, infrastructure and city image
KREMLÁČKOVÁ, Michaela
This diploma thesis is a summary of urban geographic and other observations about the city of Jihlava ? for example of specific location of the city, historical development, physical geographic and social geographic characteristics and above all space structure of the city. By analysis of social geographic charasteristics I focused on territorial administrative classification of the city, on information about inhabitants and areas of production, transport and services. The central point devotes to a few analyses. It is analysis of social geographic location of the city, analysis of space structure of the city and analysis of infrastructure of the city of Jihlava whereas the most important is the analysis of space structure of Jihlava city. This analysis consists of a few subsections ? for example genetic concentric spatial structure, functional spatial structure, urban morphologic spatial structure, demographic spatial structure and other which enable a new and very interesting view of the city of Jihlava. The whole work is supplemented by maps and charts which contribute to better understanding of the problems that are explored.

Ústí nad Labem {--} location, structure, infrastructure and city image
BONESCHOVÁ, Jaroslava
This bachelor thesis is dedicated to the characterization of the city of Ústí nad Labem and concentrates mainly on its analysis from the viewpoint of location, structure, infrastructure and the overall city image. The first complex characterization of the city is divided to the description of the urban structure evolution and the physical-geographical and the socio-geographical characterizations. In the main part of the thesis we asses the location of the city from the mocro-, mezzo-, and macro point of view. Then we focus on the urban structure analysis genetic-concentric, functional, urban-morphological, social and demographical urban structure of the city. We evaluace such phenomena and propose solutions in case sof threats. The thesis is supplemented with photographs documenting the urban structure, urban planning and nature. In the next charter we concentrate on the city infrastructure analysis, mainly on the means of transport in the area, and also on the technical and biotical infrastructure.
