Konsistentna postavitev oznak znotraj razstavljenega diagrama 3D modelov
Full text linkThe use of labels in images represents the basics of visual object presentations that we are all familiar with. However, few know that automatic label placement in 2D or 3D space belongs to the set of NP-complete and NP-hard problems. While state-of-the-art algorithms such as hedgehog labeling already produce incredible coherent results in real-time interactive applications, they were only designed for static and non-deformable objects. Therefore, their performance decreases when combined with the dynamic and model-deforming the 3D model presentation techniques such as exploded diagrams a.k.a. exploded views, which present the structure of 3D model by "exploding" their parts.
We propose an extension of hedgehog labeling to work with exploded views by introducing clustering of model exploded parts and their labels. Clustered hedgehog labeling uses the explosion information to separate 3D space into sections belonging to individual label clusters, each running hedgehog labeling instances solely on the cluster members. The evaluation of the proposed solution and its Textplosion implementation was done by running a usability study enhanced with eye-tracking on a group of volunteers, where improvement of the original algorithm was detected. The need for 3D test models for experimentation resulted in the creation of a 3D Labeling dataset to be shared with the community in an attempt to fill the void of a missing standardized dataset for 3D labeling algorithms.Vizualna predstavitev informacij s pomočjo oznak znotraj slik nam je vsem že poznana. Redko kdo se pa zaveda, da samodejna postavitev oznak v 2D ali 3D prostoru spada med NP-polne in NP-težke probleme. Najsodobnejši in vodilni med algoritmi ježevo označevanje (hedgehog labeling) že ustvari neverjetne in časovno konsistentne postavitve oznak znotraj interaktivnih aplikacij v realnem času. Vendar tako kakor večina algoritmov za postavitev oznak v 3D prostoru predpostavlja statične in ne-spreminjajoče se objekte. Zato uspeh algoritmov močno pade kadar jih združimo s tehnikami predstavitve 3D modelov, ki modelom dodajo gibanje ali pa modele spremenijo tekom časa. Predstavnik obeh problematičnih tipov so razstavljeni diagrami 3D modelov, kjer predstavljamo strukturo modela s simulacijo eksplozije posameznih delov.
Za konsistentno postavitev oznak znotraj razstavljenega diagrama predlagamo razširitev ježevega označevanja s pomočjo gručenja »eksplodiranih« delov in njihovih oznak v razrede. Razredno ježevo označevanje (clustered hedgehog labeling) uporabi informacije o poteku premikov za razdelitev 3D prostora v podprostore dodeljene posameznim razredom oznak. Vsak izmed razredov izvaja lastno ježevo označevanje zgolj na oznakah znotraj razreda. Evalvacija predlagane metode je bila izvedena na njeni Textplosion implementaciji v obliki eksperimentov ocenitve uporabniške izkušnje s pomočjo sledenja vida prostovoljcev, kjer smo uspešno zaznali izboljšavo v izkušnji v primerjavi z osnovnim algoritmom. Zaradi potrebe po testnih 3D modelih v eksperimentu smo tudi ustvarili zbirko 3D modelov, ki jo nameravamo deliti s skupnostjo z namenom postavitve osnove za do zdaj manjkajoče standardizacije testiranja postavitev 3D oznak
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
