Analisa Fork Sepeda Jenis Carbon Fiber Road Bike Menggunakan Software Berbasis Elemen Hingga Berdasarkan Standar Pengujian Cen 14781
Get PDFDi dalam dunia sepeda, carbon fiber merupakan material
baru dalam pembuatan frame maupun fork sepeda. Tujuan dari
penelitian ini adalah melakukan analisa terhadap material carbon
fiber sebagai material fork road bike. Analisa dilakukan
berdasarkan defleksi, faktor keamanan, dan interlaminar shear
stress yang terjadi oleh pembebanan yang mengacu pada standar
pengujian CEN 14781.
Hasil yang diperoleh dari penelitian ini yaitu struktur fork
dalam kondisi tidak aman berdasarkan standar pengujian CEN
14781, dimana defleksi yang terjadi sebesar 5,24 mm untuk
pengujian static bending. Dari hasil analisa diperoleh pula
susunan kombinasi sudut ply yang terbaik untuk fork sepeda, yaitu
[0/90/45/-45/0]s dengan steel sebagai material steerer tube dan
drop out. Penambahan jumlah ply dan penggantian material pada
bagian steerer tube dan drop out fork sepeda memberikan
pengaruh yang semakin baik terhadap struktur fork, ditunjukkan
dengan nilai defleksi terbesar yang menurun dari 10,237 mm
menjadi 5,82 mm dan interlaminar shear stress terbesar yang
menurun dari 358,4 MPa menjadi 168,5 MPa.
=============================================================================
In bicycle world, carbon fiber is new material for making
of bicycle frame or fork. The purpose of this observation is to
analyze carbon fiber as road bike fork material. Analysis is done
by deflection, safety factor and interlaminar shear stress that
happened by loading which refers to testing standard CEN 14781.
The results of this study are fork structure is in not safe
condition based on testing standard CEN 14781, which the
deflection that happened as big as 5,24 mm for static bending test.
It is also known the best stacking combination as bicycle fork is
[0/90/45/-45/0]s and steel as steerer tube and drop out material.
Ply addition and material changing give a boost to strength of fork
structure, and is showed by reduction of the maximum deflection
from 10,237 mm to 5,82 mm and reduction of the maximum
interlaminar shear stress from 358,4 MPa to 168,5 MPa

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
Les registres de la Cour temporelle d'Avignon à la Bibliothèque Vaticane (Vat. lat. 14761-14781)

La Cour temporelle était l'instance judiciaire dont relevaient, au civil et au criminel, les habitants d'Avignon qui n'étaient ni clercs ni «courtisans». Les registres qui en proviennent et que conserve la Bibliothèque Vaticane, datés des années 1359 à 1375, appartiennent à trois catégories : lataria, où étaient notés les amendes et frais de justice levés à l'occasion de certains actes de procédure; enquêtes en matière criminelle; registres de sentences condamnatoires en matière criminelle. L'auteur en dresse le catalogue, en y ajoutant un fragment d'une enquête sur les prêts à intérêt datée de 1406. Des compléments fournis par les Archives Vaticanes à la série de la Bibliothèque Vaticane sont également présentés. Enfin, à l'aide du matériel ainsi recensé, on a établi des listes de magistrats de la Cour temporelle.Duval-Arnould Louis.

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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
