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. Keywords: location-based services; augmented reality; industrial heritage; tourism; Czech Republic Available in a digital repository NRGL

Deformometrická a nivelační měření v katastrálním území obce Dětmarovice v roce 2017
Kajzar, Vlastimil; Staš, Lubomír
2017 - Czech
Ústav geoniky AV ČR, v.v.i. v Ostravě byl v souvislosti s uvažovaným hlubinným dobýváním uhelných zásob a jeho možného vlivu na katastrální území Dětmarovice požádán v roce 2001 Dolem ČSA o posouzení případných vlivů poddolování na stabilitu svahů na vybrané části katastrálního území Dětmarovice. Důsledkem dobývání jsou, mimo jiné, i poklesy povrchu, což vzhledem ke stávající morfologii terénu v předmětném katastrálním území vyvolalo obavu, zda tyto poklesy nebudou dále indukovat svahové pohyby. Institute of Geonics AS CR, v.v.i. in 2001, in connection with the underground mining of coal reserves and its possible influence on the cadastral area of Dětmarovice, Ostrava was asked in 2001 to assess the possible impacts of undermining on the stability of slopes on selected parts of the cadastral territory of Dětmarovice. Consequences of the mining are, among other things, surface drops, which, due to the existing morphology of the terrain in the cadastral area in question, raised the concern that these declines would not further induce sloping movements.

CFD simulation of a free surface jet of high pressure nozzle. Jet sloping 90° 85° and 75°
Říha, Zdeněk
2017 - English
The report contains CFD results and description of the two phase flow water and air. Water comes into the computational domain through the nozzle which creates water jet. The jet falls on the wall surface where flows along the surface plate in all directions (x,y mainly). The aim of the work is to show how the falling water flows on the wall surface with help of advanced CFD model. Three cases had been solved there with a various jets sloping to the bottom surface plate. The first case contains results with configuration of the geometry for the jet sloping 90o. Second case contains results with configuration of the geometry for the jet sloping 85o and third case contains results with configuration of the geometry for the jet sloping 75o, see enclosures 1, 2 and 3. Given calculation had been done as steady state calculations. Keywords: CDF model; free surface jet; high pressure nozzle Available at various institutes of the ASCR

2017 - English
This paper addresses an experimental investigation on the feasibility of using\nabrasive water jet (AWJ) for the drilling of small-diameter holes in aeroengines\ncomponents. These components are sprayed with ceramic thermal barrier coating\n(TBC). The required holes are typically 0.5 to 1 mm in diameter with a drilling\nangle of 30 to 90 deg. The parameters of the AWJ were varied to study their effects\non both quantitative and qualitative hole drilling parameters.

Erosion capability of ultra-high-speed continuous waterjet and pulsating waterjet: the comparison
Sitek, Libor; Hlaváček, Petr; Klichová, Dagmar; Trieb, F.; Pude, F.
2017 - English
Advantages and possibilities of continuous ultra-high-speed waterjets (with\npressures of 600 MPa and more) when cutting metals are well known to\nthe professional public both from scientific studies and from practice. In addition\nto efficiency increased as water pressure increases and reduced water\nconsumption, abrasive consumption can also be reduced in the case of abrasive\nwaterjet. Ultra-high-speed waterjet technology allows not only to cut metal sheets\nwith pure water, but also allows cutting of harder materials such as ceramics.\nDespite the initial suspicion and technical problems associated with the reliability\nand sealing of some hyperpressure elements, high-pressure devices generating\nwater pressures around 600 MPa are now commercially available. However, no\ncomparison has been made so far concerning the efficiency of these jets with\nacoustically modulated high-speed pulsating waterjets using relatively low\npressures and higher water flow rates when eroding metallic materials.\nThe article compares cuts made by pure ultra-high-speed waterjet generated at\nhyperpressures (from 500 to 800 MPa) with erosive capabilities of pulsating\nwaterjets generated on the contrary at water pressures in the order of tens of MPa\non three metallic materials (stainless steel, mild steel and copper) using the same\njet hydraulic power.

Velocity measurements on continuous micro water jet using fluorescent PMMA seeding particles
Zeleňák, Michal; Ščučka, Jiří; Souček, Kamil
2017 - English
The paper deals with application of optical diagnostic techniques for velocity\nmeasurements of continuous micro water jet. The combination of Particle image\nvelocimetry, Particle tracking velocimetry, Laser induced fluorescence and\nShadowgraphy methods have been applied together with the use of fluorescent\nPMMA seeding particles. An experimental closed water circuit was designed with\na low-pressure water pump, and a series of experiments was conducted to\nmeasure the velocity of seeding particles in the water jet flow below the diamond\nmicro-nozzle outlet. The basic principles of the methods used in experiments are\nalso described. Keywords: micro water jet; fluorescent PMMA particles; velocity; LIF; PTV; PIV Available in a digital repository NRGL

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.
