A Service Oriented Architecture Supporting an Autonomous Mobile Robot for Industrial Applications
No full textThis paper presents the design and implementation of a control system for autonomous navigation based on a Service Oriented Architecture (SOA) supporting a mobile robot suitable for industrial applications. The robot is required to perform generic high-level tasks in indoor structured environments. The control architecture, developed within the Microsoft Robotics Developer Studio (MRDS), allows to encapsulate the controller functionalities as a set of services that interact and exchange data among them. This approach allows to guarantee flexibility, scalability and reliability. The accurate testing, carried out in simulated and real environments, shows good real-time performances
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
Service Oriented Soft Real-time implementation of SLAM capability for mobile robots
No full textThis paper focuses on solving practical challenges inherent from the use of state-of-art mobile robotics techniques in a resource hungry embedded mobile unit without inherent support for hard real-time operation. Such problems include real-time constraints, sensor acquisition independence from robot movement, multi-rate parallel data acquisition and memory limitations
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
Development of a Flexible Test Platform for Household Appliance Testing based on Mobile Agents
No full textThis paper describes an innovative and flexible test platform for the household appliances test based on mobile agents, in order to carry out efficient data collection and analysis and to assist products design by providing defective components identification. The diagnostic system is specifically designed for the life-test laboratories, in which the mobile agent performs several measurements on many products over a long period of time, using different sensors mounted on board of the platform. The architecture and realization of the test platform is illustrated and described in details, focusing on the aspects related with autonomous mobile agent development, such as: navigation and perception in an indoor highly structured environment with unpredictable minor changes, manipulation and physical interaction with the product, image recognition of the environment and of the product. A prototype test platform has been developed and the first results show that it is feasible and effective for the improvement of the level of automation and quality of a life-test laboratory
