No full textSynergistic use of multiple on-chip networks for ultra-low latency and scalable distributed routing reconfiguration
No full textExtending the principle of partially good die allowance to manycore processors, and testing them over time to detect the onset of permanent faults, are only feasible through proper support in the on-chip interconnection network. In fact, this implies the ability to reconfigure the routing algorithm at runtime to reflect changes in network topologies. Current literature cannot avoid a large hardware and/or software overhead when tackling this challenge. This paper exploits the existence of multiple physical networks in industry-relevant manycore processors in a synergistic way, for the sake of fast and scalable distributed reconfiguration of the routing function at runtime
Transparent lifetime built-in self-testing of networks-on-chip through the selective non-concurrent testing of their communication channels
No full textIn some application domains (e.g., mission-critical systems), proactive detection of reliability threats or prompt fault containment are mandatory in order to avoid or limit the malfunctioning of electronic systems as an effect of the onset of permanent faults at runtime. As an essential milestone for the design of these systems, this paper presents a distributed and lightweight control framework for the built-in self-testing of networks-on-chip (NoCs) in the background while applications are running. The main idea of this concurrent online testing framework consists of modularizing the NoC into communication channels, of selectively taking such channels offline for non-concurrent testing, and of reconfiguring the NoC routing function to route packets around the temporary blockages to preserve network availability
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
