IIT-H Students' Start-up: A 'Do-it-yourself' Model of Video Making
Full text linkAnkit Mishra, Mudit Tanwani, Sanyam Kapoor and Chinmay Jindal have set up Storyxpress. A brand
video which costs as less as five US dollars is what Storyxpress, a software application developed
by them, offers. Started two years ago when Ankit and Mudit were in their third year and Sanyam
Kapoor and Chinmay Jindal in the first year, Storyxpress evolved from a college startup idea to a
full-fledged software application today. Storyxpress has won an award for student innovation among
start-ups from the Hyderabad Software Enterprises Association (HYSEA
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
Scalable compiler optimizations for improving the memory system performance in multi- and many-core processors
Full text linkUniversity of Minnesota Ph.D. dissertation. September 2014. Major: Computer Science. Advisor: Pen-Chung Yew. 1 computer file (PDF); x, 158 pages.The last decade has seen the transition from unicore processors to their multi-core (and now many-core) counterparts. This transition has brought about renewed focus on compiler developers to extract performance from these parallel processors. In addition to extracting parallelism, another important responsibility of a parallelizing (or optimizing) compiler is to improve the memory system performance of the source program. This is particularly important because the multi-cores have accentuated the memory-wall and the bandwidth-wall.In this thesis, we identify three key challenges facing the compiler developers on current processors. These include,(1) the diverse set of microarchitectures existent at any time, and more importantly, the changes in micrarchitecture between generations. (2) Poor show of compilers in real applications that contain large scope of statements amenable for optimization. (3) Unscalability of compilers - this is a traditional limitation of compilers where the compilers choose to optimize small scopes to contain the compile time and memory requirement, and thus loose optimization opportunities.In this thesis, we make the following contributions to address the above challenges.(1) We revisit three compiler optimizations (loop tiling and loop fusion for enhancing temporal locality and data prefetching for hiding memory latency) for improving memory (and parallel) performance in light of the various recent advances in microarchitecture, including deeper memory hierarchy, the multithreading technology, the (short-vector) SIMDization technology, and hardware prefetching, and propose generic algorithms implementable in production compilers for a range of processors.(2) We propose wise heuristics in a cost model to choose good statements to fuse, and also improve dependence analysis to not loose critical fusion opportunity in application programs when it exists.(3) The final contribution of this thesis is a solution to the unscalability problem. Based on program semantics, we devise a way to represent the entire program with much fewer representative statements and dependences, leading to significantly improved compile time and memory requirement for compilation. Thus, real applications can now be optimized not only efficiently, but at very low overhead.Mehta, Sanyam. (2014).
