    Population distribution by selected road network elements - comparison of centroids, geocoded addresses, built-up areas and total areas on the example of Slovak communes

    Two research objectives can be identified in the presented paper. The first one was the development of a point layer, which would abstract from the position of a central point depending on the shape of the territory of the respective spatial unit (commune), and would express the position of a commune as regards the location of the point in the area of the commune built-up area. For such purpose, a geocoding algorithm from Google was used, for which it was possible to prepare a final dot map layer without any terrain layout, as the geocoding algorithm processes only simple text addresses of the relevant spatial units. Such an obtained dot layer was compared with the layer of centroids and the achieved differences were visualised. Another objective was to compare different methods of population distribution interpretation from the selected road network elements at the commune level. Point layers in the form of centroids and geocodes were compared with the spatial population distribution on the basis of the total area and built-up area of a commune. It is more suitable to use geocodes as the holder of statistical information in comparison with commune centroids, in particular in the areas with marked vertical division of the terrain. In assessing population distribution, the obtained values are much closer to the expression of the identical indicator calculated for the built-up area of a commune that we consider most accurate, which is also documented by the average percentage deviations between particular interpretations of population distribution.

    One of the main features of today's information society is the availability of data of various kinds provided by various companies and organizations. In the following paper, we focus on evaluating the dynamics of development and the current state of existence of web pages of communes in Slovakia, which represent a database of their activities and serve as the main communication channel between citizens and self-government representatives. Another important channel is social networks, which are still enjoying huge popularity among internet users. On the basis of the results of an online questionnaire that involved almost 60% of the addressed self-governments, we will point out the adaptation of self-governments to the use of social networks. An important task of such research is the distribution of the obtained results to end users as well. This is achieved through an example of a description of basic technical and functional specifications by using the web page created by the authors of the contribution. This web page has the ambition of becoming a sort of central access point for all those interested in information about communes in Slovakia. By means of standard tabular, but also interactive graphic and map outputs, it gives an idea of selected indicators of self-governments in a user-friendly form, thus helping to increase client awareness of this specific issue.One of the main features of today's information society is the availabilityof data of various kinds provided by various companies and organisations.

    Spatial autocorrelation of communes websites: A case study of the region Stredné Považie in Slovakia

    Since its origination the Internet has been the basic communication channel through which e-Government processes in our society are carried out. The basic element of such processes is an existing website. This paper is the result of long-term research during which the authors collected information on the presence or absence of websites of self-governments in Slovakia. The output can be divided into two main parts. The first one, on the basis of the acquired data, evaluates the overall trend of self-government websites between 2008–2012. The results were distributed in the form of a website devoted to communes of Slovakia, using technology enabling the graphical and cartographic interpretation of the results. In the second part, on the basis of the gathered data, the authors applied spatial autocorrelation, specifically the ‘join count statistics’ method with the subsequent application to selected phenomenon in society, in particular the occurrence of websites of a selected region of Stredné Považie in Slovakia at the same time interval. This way the authors wanted to point out the interaction of communes in the development of websites, whether through inspiration or rivalry among neighbouring communes. From this point of view, mainly in the first period under review (2008), positive spatial autocorrelation is apparent in the occurrence of communes with websites

    Tato diplomová práce se zabývá moderními technologiemi grafického hardware a jeho využitím pro obecné výpočty. Soustředí se především na architekturu unifikovaných procesorů a implementaci algoritmů pomocí programového rozhraní CUDA. Základem je zvolit vhodný algoritmus demonstrující výkon GPU. Cílem této práce je implementace multiplatformní knihovny, která poskytne vektorizaci diskrétních volumetrických dat. Pro tento proces byl zvolen algoritmus Marching cubes, hledající povrch nasnímaného objektu. V knihovně bude obsažena jak část pro zpracování na grafickém zařízení, tak na CPU. Na závěr obě varianty porovnáme a vyjádříme se k výhodám či nevýhodám těchto přístupů.This master thesis deals with modern technologies in graphic hardware and using their for general purpose computing. It is primary focused on architecture of unified processors and algorithm implementation via CUDA programming interface. Thesis base is to choose suited algorithm for GPU horsepower demonstration. Main aim of this work is implementation of multiplatform library offering algorithms for discrete volumetric data vectorization. For this purpose was chosen algorithm Marching cubes that is able to find surface of processed object. In created library will be contained algorithm runnable on graphic device and also one runnable on CPU. Finally we compare both variants and discuss their pros and cons.
