International collaboration is an important factor stimulating the advancement of national research and development. In this paper we use bibliometric analysis for the evaluation of the extent and the intensity of collaboration of the EU countries with partners beyond the EU group. The main partner of EU is the USA whose authors participate on nearly one tenth of the European scientifi c publications. Within the 6th and 7th Framework Programme, measured by the number of R&D teams, Russia dominates. Former socialist countries exhibit a broader orientation towards Russia and other countries of the former USSR than the EU-15 countries. The number of American R&D teams involved in the collaboration with Czech subjects is about only one third of the Russian ones.

Integrace českého výzkumu a vývoje v oblasti energetiky do meziná-rodních programů otevírá možnosti účasti na finančnč náročných pro-jektech a iniciativách, které nelze realizovat na národní úrovni. Cílem příspčvku je posoudit s využitím kvantitativních indikátorů, jak se ČR zapojuje do mezinárodních projektů VaV a jaká je úroveň výsledků této spolupráce v publikační sféře. Oborová struktura zapojení ČR v meziná-rodním energetickém výzkumu je značnč nevyrovnaná. Celkovč v zapojení v 7. rámcovém programu je ČR na 26. místč z EU-28, avšak v oblasti jaderné energetiky (program EURATOM) je česká účast pomčrnč vyso-ká a v tematické prioritč Jaderné štčpení tohoto programu patří české výzkumné týmy k nejaktivnčjším. Nízká úroveň participace v mezinárodních aktivitách se odráží i v celkovč nízkém podílu českých publikací v energetických oborech vytvořených v mezinárodní spolupráci, v nichž dominují práce zaměřené na oblast jaderné energetiky. Velmi nízké za-stoupení v mezinárodních publikacích má oblast obnovitelných zdrojů.

Fundamental changes that occurred in Central and Eastern Europe (including Slovakia) in recent two decades have caused that regional policy as well as regional development has become one of the hottest national policy issues. If one connects this issue with the existence of regional disparities, there is no surprise that also the EU considers this topic an extra important one. Various scholars point out that innovation policy is the right path how to achieve sustainable regional development and how to improve competitiveness of less developed regions. This article is aimed particularly at the innovation policies of the Slovak self-government regions and their outcomes.

The aim of the paper is to assess the Czech participation in international cooperation in the security research and to identify obstacles which prevent a higher involvement of research teams from the Czech Republic in this cooperation. The methodological approach to the analysis and the used data sources are briefly described in the first part of the paper. In the next part we present the results of the analysis of the participation of entities from the Czech Republic in projects dealing with security issues, which were supported by the 7th Framework Program for Research and Technological Development and Horizon 2020, and by some other programs supporting the international cooperation in R&D. The obtained information is supplemented by results of the questionnaire survey between research organizations active in security research and by the findings of the expert workshop.

This paper describes a new Slovak speech recognition dedicated corpus built from TEDx talks and Jump Slovakia lectures. The proposed speech database consists of 220 talks and lectures in total duration of about 58 hours. Annotated speech database was generated automatically in an unsupervised manner by using acoustic speech segmentation based on principal component analysis and automatic speech transcription using two complementary speech recognition systems. The evaluation data consisting of 50 manually annotated talks and lectures in total duration of about 12 hours, has been created for evaluation of the quality of Slovak speech recognition. By unsupervised automatic annotation of TEDx talks and Jump Slovakia lectures we have obtained 21.26% of new speech segments with approximately 9.44% word error rate, suitable for retraining or adaptation of acoustic models trained beforehand.
The aim of this paper is the biomechanical evaluation of the interaction between load forces to which a sitting man and the seat are exposed. All loads, which consider actual anthropometry histograms of human population (i.e. segmentation of human weight, height, centroids, gravity and shape of seat) are determined using the direct Monte Carlo Method. All inputs are based on the theory of probability (i.e. random/probabilistic inputs and outputs with respect their variabilities). A simple plane model (i.e. probabilistic normal forces and bending moments) shows a sufficient stochastic/probabilistic evaluation connected with biomechanics, ergonomics, medical engineering (implants, rehabilitation, traumatology, orthopaedics, surgery etc.) or industrial design.
The article analyses railway transport markets in three neighbouring Central European countries: the Czech Republic, Austria and Germany (specifically Bavaria and Saxony), with a focus on regional transportation. It examines the organisational form of public transport resulting from regionalisation and provides comparative case studies of regional train services in these countries. The article points out the organisational differences in public transportation between the studied regions and tries to connect these results with the supply of regional train services on various types of lines and in different geographical areas.

Cu doped transparent ZnO thin films (CZO) were sputtered on soda lime glass substrates at three different distances between substrate and target. The effects of copper doping on the structural and optical properties were investigated by X-ray diffraction (XRD) and transmittance measurements. The XRD results indicated that CZO thin films have a preferential crystallographic orientation along the hexagonal wurtzite (002) axis. With increasing the distance between substrate-target, from 4 cm to 8 cm, the refractive index of the CZO films decreased. In the visible wavelength region, the average value of the transmittance was above 80%. Thus, significant changes in the structural and optical properties have occurred due to the decrease of the distance between the target-substrate and the residual compressive stress at the film-substrate interface arising during deposition.

The energy transformations involved in the operation of the pumping installations are carried out by pumping aggregates consisting of an electric motor and a pump. In order to provide a full adaptation to the users’ variable demands, variable speed motor driven pumps are used on networks (such motors being equipped with frequency converters). The paper presents a method for determining the global efficiency of a frequency converter-asynchronous motor-pump group. The method has been implemented at the Chiriţa Pumping Station, main facility within the Iasi City water supply system.
