An analysis of daily power consumption under different On-Off IP-over-WDM translucent design approaches
No full textOn the energy and cost trade-off of different energy-aware network design strategies
No full textWe compare different energy-aware network design strategies that adapt network resources utilization to traffic variations. We show how to achieve, without extra devices, up to 26% energy savings with respect to a 100Gb/s static network
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
System and method for selecting an optical path in an optical network
No full textThe invention proposes a system and method
for selecting an optimal optical path through
which to transmit an optical signal, the optimal
optical path is one of a plurality of optical paths in
a transparent optical network. Each of the
plurality of optical paths includes a plurality of
optical elements. For each of the plurality of
optical paths,a first optical signal to noise ratio is
determined for each optical element in the
respective optical path. Then, for each of the
plurality of optical paths, nonlinear distortions
caused by each optical element in the respective
optical path are modelled as Gaussian noise and a
second optical signal to noise ratio associated with
the modelled Gaussian noise is determined.
Finally, the optimal optical path is selected using the sums of the first and second
optical signal to noise ratios, respectively

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
