Method for segmenting e.g. radially inner surface, of tire of car to discover defects and non-uniformities, involves processing image to segment image into regions corresponding to regions of tires, which do or do not belong to groove
No full textNOVELTY - The method involves irradiating a portion of a surface (5a) of a tire (P) with electromagnetic radiation including wavelength in a visible spectrum. An image of the portion of the irradiated surface is acquired. The image is processed to segment the image into regions corresponding to regions of the tires, which do or do not belong to a groove, by calculating a statistical quantity associated with irradiation by the radiation for the regions of the image and determining whether the regions of the image do or do not belong to the groove according to a value of the statistical quantity.
USE - Method for segmenting a surface e.g. radially inner surface and radially outer surface, of a tire of a car to discover defects and non-uniformities.
ADVANTAGE - The method enables improving efficiency in terms of accuracy of inspection of the tire, thus enabling the requisite defects and parameters of the surface to be detected while reducing errors with greater precision and accuracy. The method enables improving lighting and providing pre-processing of the acquired images before the inspection can be conducted with the required degree of reliability.
DETAILED DESCRIPTION - The statistical quantity is a standard deviation. INDEPENDENT CLAIMS are also included for the following:
(1) a method for detecting defects on a surface of a tire
(2) an equipment for segmenting a surface of a tire.

Method for controlling the manufacturing of tyres for wheels of vehicles
No full textA method for controlling the manufacturing of tires for wheels of vehicles includes: extracting a cured tire from a curing station, in which the cured tire has accumulated heat during a curing process; and verifying the presence of possible defects or imperfections in that cured tire. The verification includes detecting first electromagnetic radiations representative of a heat emission from different portions of the cured tire while the cured tire frees the accumulated heat; providing at least one output signal representative of the first electromagnetic radiations detected to allow an analysis of the cured tire and to verify the presence of the possible defects or imperfections. A plant for the manufacturing of tires for wheels of vehicles is also described

No full textExperimental determination of the fluctuational dissipation in YBa2Cu3O7-delta up to high magnetic fields
No full textWe measure resistive transitions in YBa2Cu3O7-delta for several orientations and strength of the applied magnetic field. Experiments show that an angular scaling takes place in the upper part of the transition, for all angles, down to a field-dependent temperature T-f(H). The fluctuations theory is shown to fully describe the experimental findings for T>T-f, including the angular scaling and the detailed temperature behavior of the resistivity. The scaling breakdown at T-f(H) is argued to be due to pinning effects on vortex lines that become relevant at low temperatures
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
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
