Establishing Industrial Parks for the Development of the Slovak Economy
No full textIndustrial parks play significant role in the economical development of every country. They create space for attracting foreign investors, producing various products and services, create favourable conditions for development of small and medium enterprises, while applying modern technologies and concentrating at production of hi-tech products. In my paper will be presented the process of establishing industrial parks in Slovakia and their contribution for the development of the slovak economy. Attention will be given to the description of various categories and types of industrial parks in Slovakia.
Optimal design of triaxial weave fabric composites for specific strength and stiffness under tension
No full textTriaxial weave fabric (TWF) composites are increasingly used in ultralight flexible structures, such as deployable antenna on spacecraft and wing skins of unmanned aerial vehicles (UAVs). High specific strength to stiffness ratios are important to avoid damage under large deflections and during folding and unfolding, whilst ensuring that they remain light weight. Genetic Algorithms (GAs) are widely used in the composite optimisation literature to find weaves that give optimal properties. Previously MLSGA-NSGAII and NSGA-II were shown to have the best performance in finding optimal schema for triaxial weave fabric composites and are used to generate Pareto Fronts of stiffness and strength. In this study the density of the material is also considered. 500 Pareto front points are achieved with 15 designs that are potentially capable of being designed for ultralight structures. A potential increase of 228.05% in the strength to stiffness ratio with increase of 149.49% in the strength is made with the same surface density as a current example. These allow selection of designs with high specific strength to stiffness ratios, ensuring practical designs that can be used for ultra-lightweight applications.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Isolation and Community in Short Story Collections by Z.Z. Packer, Jhumpa Lahiri, and Mary Gaitskill
No full textLooking at short story collections by Z.Z. Packer, Jhumpa Lahiri, and Mary Gaitskill, this work explores the protagonists\u27 development of identity in relation to others. Using relational psychoanalysis as a theoretical base, this thesis probes the tension between involvement in community and maintaining individuality
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

No full textDispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
