Přístupy ke studiu recyklace urbánního prostoru v České republice: Vývoj a perspektiva
Osman, Robert; Malý, Jiří; Klusáček, Petr
2017 - Czech
Předkládaný příspěvek se zabývá problematikou recyklace urbánních prostor, konkrétně opuštěných a nevyužívaných prostor (brownfields) v České republice. Regenerace těchto území je důležitá především z důvodu jejich ekonomického, sociálního, kulturního, symbolického, historického a environmentálního významu. Dosavadní výzkumy recyklace urbánních prostor však do jisté míry opomíjí studium samotného procesu revitalizace. V této souvislosti lze na recyklaci prostoru nahlížet prostřednictvím konceptu sítě, konkrétně skrze teorii akté síť (A-NT). Ta umožňuje nazírání recyklace území jako mobilizaci aktérské sítě. Recyklace takto pojatého prostoru pak nutně neznamená samotnou fyzickou přestavbu území z jedné funkce využití na jinou, ale vznik nového síťového prostoru, respektive transformaci jednoho síťového prostoru v jiný. Cílem příspěvku je vyzdvihnutí hlavních přínosů A-NT při studiu recyklace prostorů. Kromě teoretických východisek pro propojení A-NT s procesem revitalizace území příspěvek nabízí konkrétní příklad regenerace území, kde aplikace A-NT rozkrývá síťovou strukturu procesu regenerace, která by dosavadními přístupy ke studiu brownfields zůstala skryta.\n This paper deals with the issue of recycling urban spaces, specifically abandoned and unused areas (brownfields) in the Czech Republic. Regeneration of these areas is important especially because of their economic, social and environmental burden. Previous researches on recycling urban space, however, neglected the study of the revitalization process to some extent. Thus, a recycling space may be seen through the concept of a network, explicitly through the Actor-network theory (A-NT). Keywords: recycling of urban space; brownfields; Actor-network theory; post-socialism; Czech Republic Available in digital repository of the ASCR

Dynamization of spatial data using location-based services: Tourist potential of industrial heritage
Malý, Jiří; Krejčí, Tomáš; Trojan, Jakub; Chudáček, Stanislav; Nováková, Eva
2017 - English
The paper deals with industrial heritage and its potential in tourism. Although the post-industrial landscape is an integral part of all the countries that went through a period of de-industrialization and economic transformation, presentation and publicity of valuable industrial monuments that are linked with post-industrial landscape in many cases are not fully utilized. This paper aims to acquaint readers with a possibility of transformation of data on industrial objects into augmented reality, while using location-based services. The final result is the web-based platform allowing easy data transformation. The paper has thus largely methodological-application character. The outcomes of the testing phase indicate that information about the objects do have their limits, but respecting them brings their effective performance in augmented reality.

Srivastava, M.; Hloch, Sergej; Tripathi, R.; Chattopadhyaya, S.; Dixit, A. R.; Foldyna, Josef; Hvizdoš, P.; Fides, M.; Adamčík, P.
2017 - English
This study focusses on exploring the effect of using Pulsating water jet technology\nas a surface treatment process. The AISI 304 plate samples were subjected to\nthe treatment process using circular nozzle at different levels of pressure and\nstand-off distance combination with variation of traverse speed. For evaluating\nthe effect of peening the surface residual stress was measured using the x-ray\ndiffraction technique. The results showed that the initial tensile residual stresses\non the surface were relieved and converted to compressive residual stress.\nThe present study shows that the new technology can be used as a potential\nsurface treatment method.

Local geoheritage: its importance and potential for geotourist and recreational activities (a case study from Lomnicko area)
Kirchner, Karel; Kubalíková, Lucie; Bajer, A.
2017 - English
Geodiversity, respectively its valuable part – geoheritage is considered an important resource for the geotourism and recreation purposes. In the C.R., there are a lot of examples of such use of geoheritage: sandstone rock cities, karst areas or polygenetic relief at mountain areas and others. These geoheritage features are usually significant on the national level, their existence assure the attractiveness of the given area, enables the geotourist and recreational activities and support the local and regional development. However, in the local scale, the geodiversity (respectively geoheritage, represented by particular geosites and geomorphosites) can also serve the above mentioned purposes. The paper presents the example from Lomnicko area which can be seen as an “average” area from the geodiversity/geoheritage point of view on the national level, but on the local and regional level, there is a considerable number of geosites and geomorphosites with a potential for geotourism and recreation.

Overlapping domain decomposition preconditioners for elliptic and parabolic problems in primal and mixed form
Blaheta, Radim
2017 - English
In this lecture, we concern the numerical solution of PDE problems and describe overlapping domain decomposition, which provides a tool for the construction of parallelizable Schwarz type iterative solvers and preconditioners. The idea of using overlapping domain decomposition goes back to Schwarz alternating method from 1870, see [1]. The analysis of this alternating iterative method was evolved by great mathematicians, see e.g. S.L. Sobolev (1936), R. Courant and D. Hilbert (1937), S.G. Michlin (1951), M. Práger (1958), I. Babuška (1958), F.E. Browder (1958). The use of overlapping domain decomposition for parallel computations started in the late eighties in the work of M. Dryja and O. Widlund [4], P.L. Lions [5, 6], S. Nepomnyaschikh [7] and others and continue up to the present days. The origin of the alternating Schwarz method is nicely described in [8]. Keywords: preconditioners; Schwarz method; matrix Ma Fulltext is available at external website.

Algebraic preconditioning for Biot-Barenblatt poroelastic systems
Blaheta, Radim; Luber, Tomáš
2017 - English
Poroelastic systems describe fluid flow through porous medium coupled with deformation of the porous matrix. In this paper, the deformation is described by linear elasticity, the fluid flow is modelled as Darcy flow. The main focus is on the Biot-Barenblatt model with double porosity/double permeability flow, which distinguishes flow in two regions considered as continua. The main goal is in proposing block diagonal preconditionings to systems arising from the discretization of the Biot-Barenblatt model by a mixed finite element method in space and implicit Euler method in time and estimating the condition number for such preconditioning. The investigation of preconditioning includes its dependence on material coefficients and parameters of discretization. Keywords: poroelasticity; double permeability; preconditioning; Schur complement Fulltext is available at external website.

Standardizovaný postup identifikace segmentů předindustriální krajiny platný pro regiony Moravy
Kolejka, Jaromír; Kirchner, Karel
2017 - Czech
Česká preindustriální krajina je datována před obdobím hlavní vlny průmyslové revoluce, která je nyní kladena před rokem 1850. Jedná se o ukončení relativně nepřerušeného socioekonomického a kulturního vývoje z poloviny 17. století s ohledem na místní přírodní podmínky. Jeho zachované areály nejsou zaznamenávány v České republice s výjimkou deklarovaných a plánovaných ochranných zón. Zvláště četné menší plochy s charakteristickou prostorovou strukturou orné půdy, silnice, budovy, jezera a zalesněné plochy nebyly zaznamenávány a mapovány. Tato práce se zabývá původním procesem identifikace segmentů předindustriální krajiny. Náš přístup je založen na porovnání různých kartografických dat (historické mapy z 2. vojenského průzkumu, ukazatele náčrtů katastrálních map, aktuálních map a obrazů) a identifikační proces obsahuje pět základních kroků. The Czech pre-industrial landscape is dated to the period before the main wave of the industrial revolution, now before the year 1850. It bears the sings of relatively uninterrupted socio-economic and cultural development of the mid-17th century with regard to local natural conditions. Its surviving relics are not recorded in the Czech Republic except declared and planned landscape conservation zones. Especially numerous smaller areas with a characteristic spatial structure of arable land, roads, buildings, lakes and forested areas were not covered and mapped. The present paper deals with the original identification procedure of segments of pre-industrial landscape. Our approach is based on a comparison of the various cartographic data (historical maps from the 2nd Military Survey, indicator sketches of cadastral maps, current maps and images) and identification process contains five basic steps.
