Topography of modern age non-agricultural production in selected localities of the Český les

Práce se zabývá topografií nezemědělské výroby severní části území Českého lesa z období průmyslového rozmachu v 17. - 19. století. Konkrétní územní rozsah se týká bývalého území části tachovského panství, statku Zahájí, statku Lesná a části panství Velké Dvorce. Hlavním smyslem práce je sledování variability nezemědělské činnosti a činností s ní spojenou. Jedná se především o výrobu sklářskou, železářskou a uhlířskou, jejichž výrobní proces a zpracování se buď přímo, či nepřímo váže na vodní toky. Ze zájmového území se jedná především o bezprostřední okolí Hraničního, Celního a Kateřinského potoka.Katedra archeologieObhájenoThe thesis deals with the topography of non-agricultural production of the northern part of the National park Bohemian Forest from the period of industrial expansion (during the 17th to 19th century). Specific territorial scope covers the area of the former Tachov estate, farmhouse Zahájí, farmhouse Lesná and a large part of the estate dominion Velké Dvorce. The main aim of this thesis is to monitor the variability of agricultural activities and other activities, associated with it. This represents mainly the production of glass, iron and charcoal, which manufacturing process is directly or indirectly linked to watercourses. From the area of interest represents this primarily the immediate vicinity of the Hraniční, Celní and Kateřinský stream

Preliminary study to the temperatures of the thermocouple probes affected by the environment of heated walls

Measuring of the total temperatures of the flowing medium is one of the pivotal points in the development when a new compressor stages are tested. Measurements conducted on the test compressor indicated that in the specific cases the measured temperature can be affected by the temperature of the walls which hold thermocouple probe. By implication of this observed fact, the preliminary study about this phenomenon was investigated. It was considered the influence of the heat conduction in the body of the probe and in the thermocouples. The main aim of the study was to examine the properties and the behaviour of the thermocouple probes in various working regimes. The preliminary study was focused on the development of the tools that can be used for complex solution of the problem by using of measured data. The results of this study might help to correct measured data in the case of skewed measurements affected by surroundings of the thermocouple probes

Parametric model of ventilators simulated in OpenFOAM and Elmer

Cílem práce bylo vyvinout parametrický model ventilátoru pro CFD simulace a pevnostní výpočet jeho rotoru. Celá geometrie a výpočty byly provedeny pomocí open-source programů zejména pomocí softwarových balíčků OpenFOAM a Elmer. Hlavní skript nejdříve vygeneruje a předpřipravý řídící skripty pro výpočty pomocí m4 preprocesoru. Výpočtová sítě je generována v rámci OpenFOAMu. Pro strukturální výpočty je tato síť převedena do formátu pro Elmer. Předkládaná část práce se zabývá zejména simulacemi v oblasti domény popisující proudění nasáveného média ventilátorem. Jako příklad získaných výsledků jsou uvedeny výpočty pro různé úhlové rychlosti ventilátoru.The main goal of presented work was to develop parametric model of a ventilator for CFD and structural analysis. The whole model was designed and scripted in freely available open source programmes in particular in OpenFOAM and Elmer. The main script, which runs or generates other scripts and further control the course of simulation, was written in bash scripting language in Linux environment. Further, the scripts needed for a mesh generation and running of a simulation were prepared using m4 word pre-processor. The use of m4 allowed comfortable set up of the higher amount of scripts. Consequently, the mesh was generated for fluid and solid part of the ventilator within OpenFOAM. Although OpenFOAM offers also a few tools for structural analysis, the mesh of solid parts was transferred into Elmer mesh format with the aim to perform structural analysis in this software. This submitted paper deals namely with part concerning fluid flow through parametrized geometry with different initial conditions. As an example, two simulations were conducted for the same geometric parameters and mesh but for different angular velocity of ventilator rotation

EXCAVATIONS AT THE DARBAND-I RANIA PASS, KURDISTAN REGION OF IRAQ: REPORT ON THE 2016 AND 2017 SEASONS

International audienceThis paper presents the results of the work of the new field initiative launched by the British Museum at the Darband-i Rania pass in the Kurdistan Region of Iraq. The pass is located at the northeastern corner of Lake Dokan, where, though now subsumed into the lake, the Lower Zab flows from the Peshdar into the Rania Plain. It is a strategic location on a major route from Mesopotamia into Iran, and control of both the road and the river must always have been important. The aim of the work, which commenced in autumn of 2016, is to explore a cluster of sites that commanded the pass, with a particular focus on the first millennium b.c. Excavation is being carried out principally at two sites: Qalatga Darband, a large fortified site at the western end of the pass, and Usu Aska, a fort inside the pass itself. The occupations of these two sites are predominantly Parthian and Assyrian respectively. Smaller operations have also been carried out at Murad Rasu, a multi-period site situated on a headland across the waters on the southern shore of Lake Dokan. The results have included the discovery at Qalatga Darband of a monumental complex built of stone and roofed with terracotta roof tiles containing the smashed remains of Hellenistic statuary. Other features indicative of Hellenistic material culture are Mediterranean-type oil-presses and Corinthian column bases and capitals. At Usu Aska remains are being uncovered of an Assyrian fortification of massive proportions
