DIN EN ISO 6892-2: Wesentliche Änderungen in der Norm zum Warmzugversuch
No full textDie im Mai 2011 veröffentlichte Internationale Norm ISO 6892-2 "Metallische Werkstoffe — Zugversuch - Teil 2: Prüfverfahren bei erhöhter Temperatur" ersetzt die Europäische Norm EN 10002-5 und die Internationale Norm ISO 783.
Technische Änderungen/Ergänzungen im Vergleich zu den Vorgängernormen beziehen sich im Wesentlichen auf die Prüfgeschwindigkeiten und die Dehnungsmessung. In Anlehnung an Teil 1 der ISO 6892 (Prüfung bei Raumtemperatur) wird die Dehngeschwindigkeit als maßgebliche Prüfgeschwindigkeit mit eingeengten Bereichen (Verfahren A) empfohlen. Zum Ansetzen des Dehnungsaufnehmers und zur Festlegung der Messlänge sind nun verschiedene Verfahren möglich.
In dem Beitrag wird auch anhand von Beispielen auf mögliche Auswirkungen auf die zu bestimmenden Kennwerte eingegangen
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Rezultati laboratorijskog vlačnog ispitivanja čelika za armiranje B500B provedenog primjenom metoda A1, A2 i B norme HRN EN ISO 6892-1:2016.
No full textPrikazana je usporedba metoda vlačnog ispitivanja čelika za armiranje prema
normi HRN EN ISO 15630-1:2010 koja se poziva na normu HRN EN ISO 6892-1:2016.
Mehanička svojstva čelika ovisna su o brzini nanošenja opterećenja. Zbog toga je prema
normi HRN EN ISO 6892-1:2016 preporučena metoda A, koja koristi kontrolu brzine
deformacije. Laboratorijsko vlačno ispitivanje čelika za armiranje B500B provedeno je
primjenom metoda A1, A2 i B norme HRN EN ISO 6892-1:2016. Rezultati
ispitivanja pokazali su da neovisno o primjenjenoj metodi ispitivanja možemo očekivati
gotovo iste rezultate ispitivanja.Laboratorijsko vlačno ispitivanje čelika za armiranje
The use of standard EN ISO 6892-1 in material testing
Get PDFU ovom završnom radu opisan je postupak ispitivanja statičke vlačne čvrstoće. Završni rad se sastoji od teorijskog i eksperimentalnog dijela. U teorijskom dijelu opisana je podjela materijala, posebno su obrađeni čelici a zatim je obrađen postupak ispitivanja vlačne čvrstoće s teorijske strane. U eksperimentalnom dijelu primjenjena je norma HRN EN ISO 6892-1 u ispitivanju materijala, ispitane i izračunate vrijednosti su analizirane, te je dat zaključak.This thesis describes the procedure for testing of static tensile strength. The final work consists of theoretical and experimental part. The theoretical part describes the division of materials, with particular emphesis on steel and then a theory on procedure for testing the tensile strength. In experimental part EN ISO 6892-1 standard was used in testing of materials, measured and calculated results were analyzed and final conclusion was given
