Import 02/11/2016Ondračka, D. Návrh úprav silnice III/4739 v Dolních Datyních. Bakalářská práce. Ostrava: VŠB- Technická univerzita Ostrava, Fakulta stavební, Katedra dopravního stavitelství, 2016, 48 s. Vedoucí práce: Ing. Václav Škvain. Tato bakalářská práce se zabývá posouzením vybraného úseku silnice III/4739 v Dolních Datyních z hlediska směrových a výškových závad a následným návrhem stavebně - technických opatření zmírňujících dopad těchto závada na plynulost a bezpečnost provozu. Na základě získaných podkladů byl proveden návrh řešení těchto problémů a to pomocí přeložení trasy ve dvou úsecích a kategorijní úpravou silnice v místech, kde se navržená trasa shoduje s vedením stávající silnice. Návrh zahrnuje napojení stávajících komunikací na nově navržené přeložky, včetně zpracování orientačního odhadu nákladů těchto úprav. Návrh výrazně zkvalitní obsluhu daného území a ulehčí přístup okolních obcí do centra Havířova.This dissertation examines selected part of highway III/4739 in Dolní Datyne focusing on faults in direction and height. Subsequently, it proposes constructional measures reducing the impact of these defects on traffic continuity and improves traffic safety. The proposed solution is based on the grounds of research and would be executed by shifting of the route in two sections; followed by consequent categorical repair of the highway in places where proposed route corresponds layout of the existing highway. This proposition includes connection of current highways to newly proposed relocated trucks is included as well as estimation of the alterations costs. The recommendation in this thesis will increase the quality of service of the stated area and ease the access of surrounding towns to the centre of Havířov.227 - Katedra dopravního stavitelstvívelmi dobř

Relocation of Road III/01151 Dolní Lomna - Horni Lomna Induced by Construction of Water Reservoir

Ondračka, D. Přeložka silnice III/01151 Dolní Lomná – Horní Lomná vyvolaná výstavbou vodní nádrže. Diplomová práce. Ostrava: VŠB – Technická univerzita Ostrava, Fakulta stavební, Katedra dopravního stavitelství, 2017, 45 s. Vedoucí práce: Ing. Václav Škvain Diplomová práce se zabývá návrhem přeložky silnice III/01151 mezi Dolní a Horní Lomnou na Jablunkovsku, která bude vyvolaná předpokládanou realizací záměru vodní nádrže Horní Lomná na řece Lomné, jejíž návrh vychází z nadřazených ZÚR Moravskoslezského kraje. Diplomová práce prověřuje možnosti přeložení této silnice do nové polohy vůči levému břehu řeky Lomné (ve směru toku řeky). Přeložka je řešena variantně, přičemž na základě provedeného hodnocení je vybraná varianta doporučena k dalšímu sledovaní a přispěje k rozhodování o záměru realizace vodní nádrže Horní Lomné na řece Lomné.Relocation of the Road III/01151 Dolní Lomná – Horní Lomná induced by the Construction of the Water Reservoir. This diploma thesis deals with the proposed relocation of the Road III/01151 between Dolní and Horní Lomná in the Jablunkov region, which will be posed by the anticipated implementation of the project the Water Reservoir Horní Lomná on the river Lomná, whose proposal is based at the ZÚR the Moravian- Silesian region. The diploma thesis examines the possibilities how to transfer this road to a new position towards the left bank of the river Lomná (in the same direction as the river flows). The relocation is dealt with alternatively, while on the basis of the evaluation of the selected variant recommended for further monitoring and will contribute to making decision and the intention of the implementation of the Water Reservoir Horní Lomná on the river Lomná.227 - Katedra dopravního stavitelstvívýborn

Prediction and identification of point defect fingerprints in the X-ray photoelectron spectra of TiNx_x

We investigate the effect of selected N and Ti point defects in $B$1 TiN on N 1s and Ti 2p$_{3/2}$ binding energies (BE) by experiments and ab initio calculations. X-ray photoelectron spectroscopy (XPS) measurements of Ti-deficient TiN films reveal additional N 1s spectral components at lower binding energies. Ab initio calculations predict that these components are caused by either Ti vacancies, which induce a N 1s BE shift of $-0.53$ eV in its first N neighbors, and/or N tetrahedral interstitials, which have their N 1s BE shifted by $-1.18$ eV and also shift BE of their first N neighbors by $-0.53$ eV. However, the {\it ab initio} calculations also reveal that the tetrahedral N interstitial is unstable at room temperature. We, therefore, unambiguously attribute the detected signal to Ti vacancies. Furthermore, the vacancy concentration in Ti-deficient TiN was quantified with XPS supported by ab initio calculations. The largest BE shifts of $-1.53$, $-1.80$ and $-2.28$ eV for Ti 2p$_{3/2}$ electrons are predicted for the Ti tetrahedral, split (10$\overline{1}$)-aligned and split (111)-aligned interstitial atoms, respectively, and we, therefore, propose XPS could detect them. Other defects such as N vacancy or N split (10$\overline{1}$)-aligned interstitial introduce smaller N 1s and Ti 2p$_{3/2}$ BE shifts and are unlikely to be detectable experimentally. Our work highlights the potential of ab initio-guided XPS measurements in detecting and quantifying point defects in $B$1 TiN

NOMAD: A distributed web-based platform for managing materials science research data

NOMAD lets you manage and share your materials science data in a way that makes it truly useful to you, your group, and the community. Materials science research is becoming increasingly data-driven, which requires more effort to manage, share, and publish data. NOMAD is a web-based application that provides data management for materials science research data. In addition to core data management functions like uploading and sharing files, NOMAD allows structured data entry using customizable forms providing the software with electronic laboratory notebook (ELN) functionalities. It automatically extracts rich metadata from supported file formats, normalizes and converts data from these formats, and provides a faceted search with materials science-specific filters based on extracted metadata. NOMAD integrates data analysis and machine learning tools. Installations of NOMAD can be connected to share data between research institutes and can publish data to an open central NOMAD service. The NOMAD software is distributed as a Docker image to create data management services and as a Python package to automate the client's use of these services
