Lefroyothrips varatharajani Rachana & Manjunath
No full textLefroyothrips varatharajani Rachana & Manjunath (Figs 6, 16, 24–26) Lefroyothrips varatharajani Rachana & Manjunath, 2020: 592 Based on 16 females and 8 males from Mimusops elengi taken 11.iii. 2020 in India, Bengaluru, this species is here recorded from Western Australia and New Caledonia. This distribution seems remarkable but is not greatly different from that indicated above for L. fasciatus. The specimens studied listed below agree fully with the recent detailed description of this species. It is probably closely related to L. lefroyi but has the metascutum only weakly reticulate (cf Figs 14, 16). Female macroptera. Body and legs yellow, posterior tergites brownish-yellow; antennal segments IV–VI brown or with brown marking (Fig. 6); fore wings pale with two short shaded areas, at veinal fork and subapically. With the character states of the generic diagnosis. Ocellar setae pair III slightly shorter than distance between posterior ocelli (Fig. 24); postocular setae in single row with S2 sometimes slightly displaced posteriorly. Metascutum weakly reticulate (Fig. 16), CPS on posterior third of sclerite and slightly variable in position. Fore wing first vein distally with 1 or 2 setae. Sternite VII setae S2 arise at posterior margin. Male macroptera. Similar to female; tergite VIII with long comb, IX with 3 pairs of stout setae (Fig. 25); sternites III–VII with transverse pore plate close to anterior margin (Fig. 26). Specimens studied. Western Australia, Kununnura, Frank Wise Institute, 2 females from grasses, 24.ii.2005 (LAM). New Caledonia, La Foa, 2 females, 4 males from Pouteria sapota fls, 9.iv.2012 (LAM) (in ANIC).Published as part of Mound, L. A. & Ng, Y.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Distributed PC Based Routers: Bottleneck Analysis and Architecture Proposal
No full textRecent research in the different functional areas of modern routers have made proposals that can greatly increase the efficiency of these machines. Most of these proposals can be implemented quickly and often efficiently in software. We wish to use personal computers as forwarders in a network to utilize the advances made by researchers. We therefore examine the ability of a personal computer to act as a router. We analyze the performance of a single general purpose computer and show that I/O is the primary bottleneck. We then study the performance of distributed router composed of multiple general purpose computers. We study the performance of a star topology and through experimental results we show that although its performance is good, it lacks flexibility in its design. We compare it with a multistage architecture. We conclude with a proposal for an architecture that provides us with a forwarder that is both flexible and scalable.© IEE
Minimizing Absolute Gaussian Curvature Locally
No full textOne of the remaining challenges when reconstructing a surface from a
finite sample is recovering non-smooth surface features like sharp
edges. There is practical evidence showing that a two step approach
could be an aid to this problem, namely, first computing a
polyhedral reconstruction isotopic to the sampled surface, and
secondly minimizing the absolute Gaussian curvature of this
reconstruction globally. The first step ensures topological
correctness and the second step improves the geometric accuracy of
the reconstruction in the presence of sharp features without
changing its topology. Unfortunately it is computationally hard to
minimize the absolute Gaussian curvature globally. Hence we study a
local variant of absolute Gaussian curvature minimization problem
which is still meaningful in the context of surface
fairing. Absolute Gaussian curvature like Gaussian curvature is
concentrated at the vertices of a polyhedral surface embedded into
. Local optimization tries to move a single vertex in
space such that the absolute Gaussian curvature at this vertex is
minimized. We show that in general it is algebraically hard to find
the optimal position of a vertex. By algebraically hard we mean that
in general an optimal solution is not constructible, i.e., there
exist no finite sequence of expressions starting with rational numbers,
where each expression is either the sum, difference,
product, quotient or 'th root of preceding expressions and the
last expressions give the coordinates of an optimal solution. Hence
the only option left is to approximate the optimal position. We
provide an approximation scheme for the minimum possible value of
the absolute Gaussian curvature at a vertex
Variations on the Author
No full text“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
