Enhancing Gadgets for Blinds Through Scale Invariant Feature Transform
No full textICT can help blind people in movement and direction-finding tasks. This paper proposes a new methodology for safe mobility based on scale invariant feature transform (SIFT) that is expected to lead to higher precision and accuracy. Various existing gadgets for visually impaired are examined, and the conclusion is that the proposed methodology can enhance these gadgets.</p
Design and Analysis of an Enhanced Multifactor Authentication Through a Covert Approach
No full textMost of the network service providers currently use two-factor authentication for their wireless networks. This exposes the network subscribers to identify theft and user’s data to security threats like snooping, sniffing, spoofing and phishing. There is need to control these problems with the use of an enhanced multi factor authentication approach. The objective of this work is to create a multi-factor authentication software for a wireless network. Multi factor authentication involves user’s knowledge factor, user’s possession factor and user’s inherence factor; that is who the user is to be presented before system access can be granted. Multi factor authentication depends mainly on three factors: (1) Something a user knows, such as a password or PIN (2) Something a user has, such as a key, a card, or another kind of token (3) Something a user is, such as a retina scan, or fingerprint. We may enhance the reliability and security of the authentication mechanism by combining multiple authentication factors into a single model. Multi factor authentication is far better if we use this schema both statically and dynamically. The three factors together provide a much higher confidence in the all prerequisite parameters of cryptography.</p
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
Encountering from inside: The Vishwakarma techne heritage and “being” in experiencing architecture / Sanjeh Kumar Raman and Safial Aqbar Zakaria
Full text linkThe process of evolving from “inside”, inherent to the design culture of Vishwakarma craftsmen in Penang, provides a holistic link to its techne heritage to define the approach, process and ethics in designing culture, and sensual and sensible spaces. The exploration of “inside” allows us to understand our being in architecture which interconnects to all beings in the world.The role of body and human senses in perceiving a phenomenon, allows for a conscious experience, where we live through them by performing the conscious act through our body; which becomes an experiential, firstperson feature, in exploring “being” in architecture
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
