Pushing SKOS
Ostrowski, Felix; Pohl, Adrian
2018 - English
This presentation introduces the simple knowledge organization hub (skohub), a proof of concept web service that allows to do just that based on current web standards. Given a SKOS vocubulary, the service publishes it on the web, providing RDF serializations along with a human-readable HTML front end. For each topic described in the vocabulary, a Linked Data Notifications inbox is provided, making it possible to publish and receive notifications about resources related to that topic. Finally, WebSub enables subscriptions for push notifications about resources matching a topic. Keywords: organizace znalostí; knowledge organization; SKOS vocubulary; linked data; věcné slovníky; standardy Available in the NTK library.

A Machine for Automatic Subject Indexing Using ToC
Pokorný, Jan
2018 - English
The technology developed in the National Library of Technology can extract a document’s table of content (TOC), generate relevant keywords, and suggest terms for various classification schemas (UDC, DDC, LCC, Conspectus). It can fully or substantially automate the process of generating subject access, unite it across libraries, and significantly increase accuracy and relevancy compared to subject assignments by non-specialist catalogers. Such increased quality in subject access terms is often seen in the superior subject facets generated by discovery systems and library OPAC advanced search forms. Keywords: automatická klasifikace; automatic classification; indexní analýza; věcný popis; identifikační popis; optické zpracování znaků Available in the NTK library.

The ARCLib Project
Růžička, Michal
2018 - English
The talk informs about the Czech ARCLib project. One of the main goals of the project is the development of an open-source solution for a bit-level and logical preservation of digital documents, respecting the national and international standards as well as the needs of all types of libraries in the Czech Republic. The mission of the ARCLib project lies, among others, in creating a solution that will allow institutions to implement all of the OAIS functional modules and entities, considering institutions’ information model. The architecture is planned as open and modular and the final product will be able to ingest, validate and store data from a majority of software products used for creating, disseminating and archiving libraries’ digital and digitised data in the Czech Republic. Keywords: dlouhodobá ochrana; model OAIS; long-term preservation; bit-level pritection; otevřený software; metodologie; informační systémy Available in the NTK library.

Rethinking the IT system architecture
Berthold, Henrike
2018 - English
The Saxon State and University Library in Dresden (SLUB) is the university library of Dresden University of Technology (TUD) and the state library of Saxony with a history starting in1556. Because of these two roles, it is an independent research institution with a range of tasks. They include services for TUD, such as an open access repository, support for specific research communities, collection and long-term preservation of digital documents published in Saxony, and internal production and processing workflows. In the presentation I will present the target IT infrastructure, the background of some design decisions, the challenges we have identified and the projects we currently run to develop our infrastructure towards the target one. Keywords: architektura výpočetních systémů; knihovny; univerzity; výpočetní technika Available in the NTK library.

Proposal for loading tests of bridges - simulation and laboratory experiments
Bayer, Jan; Urushadze, Shota; Černý, Miloš
2018 - English
A new dynamic load testing of bridges is proposed and theoretically investigated. A transient analysis of passing vehicle over a bridge in ANSYS and an analytical program in MATLAB for the transient solution of piecewise linear mechanical structures were developed to assess the effects of the proposed dynamic load on a bridge model. According to the first laboratory experiments, it seems that the proposed travelling impulse load could surpass some of the shortcomings and limitations of the currently applied methods of bridge testing. The investigation is a part of a project aimed at drive-by identification of dynamic properties of bridges and further experimental and analytical research will follow. Keywords: dynamic loading tests; transient analysis; vibrations; vehicle-bridge interaction Available at various institutes of the ASCR

Lávka pro pěší Radotín - zatížení větrem dle EN 1991-1-4 a měření ve větrném tunelu
Göringer, J.; Hračov, Stanislav; Macháček, Michael
2018 - Czech
S ohledem na atypickou konstrukci lávky v Radotíně bylo nutno v rámci statického ověření řešit nestandardní účinky zatížení větrem, kdy EN 1991-1-4 poskytuje pro takto atypické konstrukce jen málo podpory. Zatížení větrem u takovéto konstrukce nevystupuje pouze jako náhradní statický účinek, ale zejména je nutné posoudit případné ztráty aerodynamické stability. Příspěvek předkládá postup stanovení problematiky podle EN 1991-1-4 včetně porovnání s výsledky z větrného tunelu. Due to the atypical design of the footbridge in Radotín the procedures for evaluation of the force coefficients presented in EN 1991-1-4 were experimentally verified in the wind tunnel. For the lack of the information about the structure behaviour on the edge of the aerodynamic instability the critical velocity for flutter was experimentally verified as well. The paper presents comparison of the approaches from EN 1991-1-4 with the results of the experiment. Keywords: wind load; footbridge; wind tunnel experiments Available at various institutes of the ASCR

Tourist interest in illicit zone of ice caves
Nováková, Eva; Kuda, František; Kubalíková, Lucie
2018 - English
Ledové sluje (Ice Caves) in the Podyjí National Park represents one of the most spectacular sites within the area. It consists of the large boulder field and several pseudokarst caverns on the north-western slope of the ridge that are very important from the ecological and geomorphological point of view. The access to the site is restricted for the visitors of National Park as there exists a risk of damage and disturbance of these unique phenomena; tourist can use the marked paths leading around the site, they can reach the top part of the ridge.\nCurrently, there are only several persons who have legal access to the site (employees of the National Park Administration and other researches with the permission issued by NP Administration). However, the installed sensor that counts the passages proved that the site is visited more frequently than it should be. The number of people who visit this site (situated within the first zone of National Park where there is no marked path and so the access is forbidden by decree) is quite alarming. Based on these findings, some proposals for the solution of this unfavourable situation are proposed and other possibilities how to avoid this undesirable phenomenon are discussed.\n Keywords: Podyji National Park; restricted area; passages monitoring Available in a digital repository NRGL

In Out, In Out, And Shake It All About
Stevenson, Jane
2018 - English
The Archives Hub blends data. We bring together descriptions of archives, archival resources and repositories in a way that enables us to present an effective and valuable service through our website. We spent two years creating an entirely new system that was built upon the principle of bringing in data from different sources and providing that data for different purposes. I would like to give some insights from our experience of doing this, and consider whether we have created something innovative and with inherent potential for future development. I will talk about the architecture that we wanted to create, the workflow that we believed to be essential to our aims, and the challenges that we faced in being able to create a blend of data that could be successfully deblended in different ways. It required a great deal of thought and planning in terms of what we wanted to achieve, how we should process the data to fulfil those aims, and how we would work with data contributors, who were essential to our success. Over a year after going live with the new service, have we achieved our aim of more consistent, standardised data, and have we provided the realistic potential for the data to be re-used? I will give examples of where I think we have fulfilled our aims and where we still have issues. I will argue that the ability to blend/deblend relies upon systems and technology, but it also relies upon people and their habits, expectations, understanding and ambitions. Keywords: API; standardy; archivy; teorie dat; elektronické zdroje Available in the NTK library.
