Set-Valued Analysis
No full textSet-valued analysis is an important and somehow strange field, with unexpected applications in
economics, game theory, decision making, nonlinear programming, biomathematics and statistics.
This book highlights some interesting subjects in set-valued analysis, both theoretical and
practical. These topics cover various areas, such as set-valued measures and integrals, applications to
differential inclusions and decision making, and related topics in measure theory.
The papers are listed in order of publication.

No full textWe present in this survey some results regarding Riemann_Lebesgue
integrability with respect to arbitrary non-additive set functions
On computational evaluation of stress concentration using micropolar elasticity
No full textWe discuss the implementation the finite element approach to the linear micropolar elasticity in order to perform the analysis of the stress concentration near holes and notches. Within the micropolar elasticity we analyze the behaviour of such microstructured solids as foams and bones. With developed new finite element few problems are analyzed where the influence of the microstructure may be important. The provided comparison of solutions obtained within the micropolar and classical elasticity show the influence of micropolar properties on stress concentration near notches and contact areas

Sensor Module for Monitoring Wine Fermentation Process
No full textThis paper presents a module for monitoring the grape fermentation process constructed of low cost sensors for temperature, wine acidity (pH), alcohol and carbon dioxide released gases. Sensor values are recorded over the wine fermentation process and are sent through wireless modules in real time to a server. Constituent part of the module is a microcontroller PIC16F877A. It processes data received from sensors and sends them to the server through Ethernet controller ENC28J60. The main advantage of this low cost prototype is the possibility to be used by small winemakers for control and monitoring of a grape fermentation process. The proposed system has been tested in a winery in the Tikves region and it fulfilled the initial expectations
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
