Construction and validation of a reconfigurable computer cluster.
No full textIncludes bibliographical references (p. 172).Cluster computing networks multiple computers (nodes) to exploit their parallel processing power. By pooling resources of multiple computers, computations can be decomposed and allocated across nodes with partial solutions collected and combined to form a complete solution (scatter and gather). By augmenting cluster nodes with reconfigurable hardware, systems can be configured with assistive devices that improve their computational performance; thus reducing computation time and increasing computational flexibility. This thesis evaluates a cluster of 16 Virtex II Pro Development boards that were integrated as an experimental cluster. The well-known 3DES algorithm was used to measure the runtime of multiple partitioned datasets (1 to 16 partitions) to quantify the execution speedup over a varying number of nodes. The results showed that performance can be improved with hardware acceleration, although there is complex interplay between node communication and file I/O timing that impacts the magnitude of the speedup.by Willis Scott Troy.M.S.E.C.E
Energy cultures framework and the Otago Home Upgrade Programme
No full textThe Otago Home Upgrade Programme is a pilot programme resourced by EECA to trial a new approach in delivering energy wellbeing. So far we’ve visited over 50 homes in Otago and a raft of interventions are in motion. We’re finding people in stressful situations through poverty and isolation or simply at a loss when faced with a critical repair / essential maintenance. Each case is unique and presents both opportunities and challenges.One of our challenges is evaluating how effective our home interventions are. We’re using the energy cultures framework to structure our evaluation process as we go, assess the impact of our interventions, and understand both the value for money in delivery and overall return on investment from a holistic perspective. We want to be able to inform future energy wellbeing work nationally. As we had expected, action research is messy but exciting.Our presentation details our approach. We will present preliminary data and use case studies to illustrate the range of issues we’re uncovering. This is work in progress, a snapshot, as we work with whanau to improve their material situation, change behaviours for the better and shift norms, to achieve energy wellbeing
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
