Radio Frequency Fingerprints vs. Physical Unclonable Functions - Are They Twins, Competitors, or Allies?
Full text linkPrivacy breaches and online frauds are grave concerns in pervasive computing. Device identification is the first line of defense to detect and stop fraud. Conventional device authentication schemes using software addresses as identities or static pre-programmed secret keys are vulnerable to tampering and memory attacks. This article reviews two emerging lightweight hardware-oriented solutions to avoid these problems, namely radio frequency fingerprint (RFF) identification and physical unclonable function (PUF) authentication. Their operating principles and protocols are first introduced, followed by a scrutiny of their common and distinctive features, and a discussion of the stumbling blocks in the way of their market adoption. Finally, we envisage a combined mutual authentication and key establishment scheme to shed light on their synergy
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
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
Spectral techniques in digital logic
No full textIn digital logic design, spectral techniques have been used for more than 30 years. The bottleneck of spectral techniques has been the exponential resources required to calculate and store the spectral coefficients. Recently, spectral techniques coupled with efficient data structures like Cube Calculus and Binary Decision Diagram have evolved to address this issue. In this thesis, relations between spectral data and these reduced representations are investigated in a different perspective. The goal is to achieve an unified procedure for the mutual conversions between spectra and reduced representations for various transforms, with or without a recursive structure, for both completely and incompletely specified logic functions.Doctor of Philosophy (EEE
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
Electrical and electronic engineering students' perspectives on transferable skill acquisition
No full textA recent study of the prospective employers of new engineers in Singapore indicates that the employers are now looking for graduates with more than technical proficiency. They require people who are also good communicators, flexible, analytical, creative and attuned to the need of lifelong learning. The career of engineers appears to be at a turning point at the beginning of the twenty-first century. It is evolving from an occupation that provides employers and clients with competent technical advice to a profession that serves the community in a socially responsible manner. In the past engineering education has catered for the former: whereas increasingly more employers and the professional societies demand the latter.A new educational approach is needed to address these changing requirements. There is a need to prepare the undergraduate with an understanding of the social context with which they will work, together with skills in critical analysis and ethical judgment and an ability to assess long-term consequences of their work. At the same time these changes have occurred there has been a drive to broaden the base of the engineering undergraduate curriculum in Singapore. The fundamental question that leads to this advocate is whether the engineering curriculum, as it exists today. is adequate to prepare the engineers of tomorrow.This study establishes that within the School of Electrical and Electronic Engineering of Nanyang Technological University, transferable skills are being addressed in general, that in the eyes of the students, some of the skill sets have been over emphasized while some important skills have been neglected. The study also reveals the extent to which students are aware of the relative importance of some skills and attitudes at the workplace.Despite the number of formal reports that have to be submitted each year by the students, the survey shows that the students are still not proficient in written communication skills. This and other preliminary findings in this report have led to further questions as to whether generic or transferable skills are best taught and learnt in separate subjects where the development of such skills is the focus of the subject or whether they should be designed to be part of the context of a technical subject.There is much to be said for incorporating skills development in technical subject and the curriculum revision in the school of EEE. Analyses of the survey should be the cause of serious critical reflection on our plans and practices. Consequently, some recommendations for improving the teaching and learning of transferable skills and further research focuses are provided
