Leveraging wireless network virtualizaton for flexible sharing of WLANs
No full textProviding air-time guarantees across a group of clients forms a fundamental building block in sharing an access point (AP) across different virtual network service providers. Though this problem has a relatively simple solution for downlink group scheduling through traffic engineering at the AP, solving this problem for uplink (UL) traffic presents a challenge for fair sharing of wireless hotspots. Among other issues, the mechanism for uplink traffic control has to scale across a large user base, and provide flexible operation irrespective of the client channel conditions and network traffic loads. In this thesis the SplitAP architecture is proposed that addresses the problem of sharing uplink airtime across groups of users by extending the idea of network virtualization. The architecture discussed in this thesis allows different algorithms to be deployed on it for enforcing UL airtime fairness across different client groups. In this thesis, the design features of the SplitAP architecture are highlighted followed by results from evaluation on a prototype deployed with the two algorithms for controlling UL group fairness like: (1) Linear Proportional Feedback Control (LPFC) and (2) Linear Proportional Feedback Control plus (LPFC+). Performance comparisons on the ORBIT testbed show that the proposed algorithms are capable of providing group air-time fairness across wireless clients irrespective of the network volume, and traffic type. The algorithms show up to 40% improvement with a modified Jain fairness index.M.S.Includes bibliographical referencesby Dipti Vet
2015 Nepal Earthquake lessons for COVID-19: how to put women at the forefront of the crisis and recovery
No full text5 years on from the devasting earthquake in Nepal, Kripa Basnyat (LSE) and Dipti Tamang (Darjeeling Government College in West Bengal, India) explain the fundamental role Nepalese women played in the country's response to the natural disaster, and what lessons we can learn when confronting the country's response to current COVID-19 global epidemic
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
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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
