SAP HANA Platform

Tato práce pojednává o databázi pracující v paměti nazývané SAP HANA. Detailně popisuje architekturu a nové technologie, které tato databáze využívá. V další části se zabývá porovnáním rychlosti provedení vkládání a vybírání záznamů z databáze se stávající používanou relační databází MaxDB. Pro účely tohoto testování jsem vytvořil jednoduchou aplikaci v jazyce ABAP, která umožňuje testy provádět a zobrazuje jejich výsledky. Ty jsou shrnuty v poslední kapitole a ukazují SAP HANA jako jednoznačně rychlejší ve vybírání dat, avšak srovnatelnou, či pomalejší při vkládání dat do databáze. Přínos mé práce vidím v shrnutí podstatných změn, které s sebou data uložená v paměti přináší a názorné srovnání rychlosti provedení základních typů dotazů.This thesis discusses the in-memory database called SAP HANA. It describes in detail the architecture and new technologies used in this type of database. The next section presents a comparison of speed of the inserting and selecting data from the database with existing relational database MaxDB. For the purposes of this testing I created a simple application in ABAP language, which allows user to perform and display their results. These are summarized in the last chapter and demonstrate SAP HANA as clearly faster during selection of data, but comparable, or slower when inserting data into the database. I see contribution of my work in the summary of significant changes that come with data stored in the main memory and brings comparison of speed of basic types of queries.

Geometrie kvarcitových těles v okolí Příchovic

Quarzite as a metasedimentary rock is usually figured in prolongated bands in geological maps. But muscovite quartzite from Krkonoše-Jizera Crystalline Unit in SE surrounding of Příchovice village forms irregular shapes in detailed geological maps (e.g., Mrázová – Štěpánek 2007, see Fig. 1), which do not allow simple interpretation of the geometry of quartzite bodies. To find correct 3D geometry of the bodies, we used standard methods of detailed mapping and documentation of outcrops as well as detailed structural analysis. Locations of terrain edges with quartzite outcrops have been indicated in the map (Fig. 3 –A, B, C). Generaly sub-horizontal to moderately dipping metamorphic foliation has been found. Foliation poles make wide girdle in the plot (Fig. 2) which indicates sub-cylindrical fold structure with horizontal axis in the NW–SE direction.Studied area can be geomorphologically divided into two different parts. The northeastern part of the territory is sub-horizontal plateau, while the southwestern part is generally inclined to the southwest. In the second part, the metamorphic foliation dips to the southwest under such angle, that it seems to be parallel to the inclination of the slope, see the old quarry (Fig. 3B) and SW part of Velká bílá skála (Fig. 3A). The last one show us bent outcrop respecting the change in slope inclination. Large shear bands were directly observed as a part of S-C structure. It indicates that SW limb of the fold was strained under simple shear condition with the drop SW kinematics (Fig. 4). Change in orientation of SW-dipping fold limb was produced by a ductile shear zone.Based on a combination of metamorphic foliation orientation of quartzite and field edges, we can interpret quartzite rocks as a part of one platy body, which forms the overall morphology of the landscape south of Příchovice. In the plateau, erosion stopped at subhorizontally oriented part of the quartzite layer, while denudation of the SW limb of the large fold predeterminates the inclined slope surface to the SW (Fig. 3D). Relics of thin overlying rocks remaining on quartzite in some places and erosion of the small creeks produce bizarre forms in geological map, which seems to be difficult to understand. This study has shown that such complex structure can be decrypted using the detailed structural analysis. In this case it was shown that quartzite forms a relatively simple body which was only slightly bent due to simple shear deformation.

Single-layer graphene on epitaxial FeRh thin films

Graphene is a 2D material that displays excellent electronic transport properties with prospective applications in many fields. Inducing and controlling magnetism in the graphene layer, for instance by proximity of magnetic materials, may enable its utilization in spintronic devices. This paper presents fabrication and detailed characterization of single-layer graphene formed on the surface of epitaxial FeRh thin films. The magnetic state of the FeRh surface can be controlled by temperature, magnetic field or strain due to interconnected order parameters. Characterization of graphene layers by X-ray Photoemission and X-ray Absorption Spectroscopy, Low-Energy Ion Scattering, Scanning Tunneling Microscopy, and Low-Energy Electron Microscopy shows that graphene is single-layer, polycrystalline and covers more than 97% of the substrate. Graphene displays several preferential orientations on the FeRh(0 0 1) surface with unit vectors of graphene rotated by 30 degrees, 15 degrees, 11 degrees, and 19 degrees with respect to FeRh substrate unit vectors. In addition, the graphene layer is capable to protect the films from oxidation when exposed to air for several months. Therefore, it can be also used as a protective layer during fabrication of magnetic elements or as an atomically thin spacer, which enables incorporation of switchable magnetic layers within stacks of 2D materials in advanced devices

Measurement of the 23Na(n,2n) cross section in 235U and 252Cf fission neutron spectra

The presented paper aims to compare the calculated and experimental reaction rates of 23Na(n,2n)22Na in a well-defined reactor spectra and in the spontaneous fission spectrum of 252Cf. The experimentally determined reaction rate, derived using gamma spectroscopy of irradiated NaF sample, is used for average cross section determination.Estimation of this cross-section is important as it is included in International Reactor Dosimetry and Fusion File and is also relevant to the correct estimation of long-term activity of Na coolant in Sodium Fast Reactors. The calculations were performed with the MCNP6 code using ENDF/B-VII.0, JEFF-3.1, JEFF-3.2, JENDL-3.3, JENDL-4, ROSFOND-2010, CENDL-3.1 and IRDFF nuclear data libraries. In the case of reactor spectrum, reasonable agreement was not achieved with any library. However, in the case of 252Cf spectrum agreement was achieved with IRDFF, JEFF-3.1 and JENDL libraries
