Ubicorder: A mobile device for situated interactions with sensor networks
No full textThe Ubicorder is a mobile, location and orientation
aware device for browsing and interacting with real-time sensor
network data. In addition to browsing data, the Ubicorder also
provides a graphical user interface (GUI) that users can use to
define inference rules. These inference rules detect sensor data
patterns, and translate them to higher-order events. Rules can
also be recursively combined to form an expressive and robust
vocabulary for detecting real-world phenomena, thus enabling
users to script higher level and relevant responses to distributed
sensor stimuli. The Ubicorder’s mobile, handheld form-factor
enables users to easily bring the device to the phenomena of
interest, hence simultaneously observe or cause real-world stimuli
and manipulate in-situ the event detection rules easily using its
graphical interface. In a first-use user study, participants without
any prior sensor network experience rated the Ubicorder highly
for its usefulness and usability when interacting with a sensor
network.Things That Think Consortiu
Metaphor and Manifestation-Cross-Reality with Ubiquitous Sensor/Actuator Networks

Mobile interface to sensor networks
Get PDFThesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2008.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 145-150).This thesis presents the Ubicorder. The Ubicorder is a location and orientation aware sensor network browsing and interactive visualization system together with in-situ event denition and identification (termed EDITY). The mobile browser allows real-time viewing of sensor network data, and enables the user to easily establish correlation between physically observed phenomena and their sensor signature. Based on the observed correlations, events are triggered every time a given set of sensor-value conditions are satised. Event rules can then be recursively combined to detect complex physical phenomena. Through a first-use user study, we evaluate the system for its usefulness and usability.by Manas Mittal.S.M
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
