Human upper limb movement assessment based on wearable sensors
No full textThe advances in medical technologies have continued to improve diagnostic and measurement devices, eventually leading to better healthcare. Glove-based systems represent one of the most important efforts aimed at acquiring hand movement data. On the other hand, inertial motion sensor is the best device for biomechanics studies because it is transportable, small, low cost, ease to be set up and less burdensome to the subject. However, processing and accuracy of the data obtained are essential issues for research purposes. The work in this dissertation are divided into three studies as follow:
The first, is to analyze hand function after hand surgery as it represents the first step the clinician has to address before defining the rehabilitation procedure and to follow the rehabilitation process for any patient. In this research, the Range of Motion (ROM) for all fingers and the ability of participants to repeat two ADL (Activities of Daily Living)-based tasks were investigated. For two patient subjects, the results were compared to that of healthy subjects. The major goals is to furnish the clinicians a tool capable of measuring objectively human hand movements and quantify the recovery of motor function during the rehabilitation.
The second study, is to validate the inertial-based system as a wearable sensor for upper limb motion analysis with optical tracking system used for co-registration as a gold standard system. The estimated angles between elbow and wrist joints of two systems were compared to address the challenges. Furtherly the inertial sensors allow clinicians to record human movements performed in normal activity daily life, so that they can remotely study the results. It is capable of tracking human upper limb motions, reconstructing the human model, monitoring human health status, positioning and recording human itinerary in ADL environment. The analyzed results will be used to know the accuracy and correlation between two systems.
The last study, is to validate the inertial sensor device with minimal human intervention. In addition, design a tri-axial rotational set up (Gimbal) to be used as a reference. The comparison between the actual angular velocity of the inertial sensor and different constant angular speeds of Gimbal was done to calculate the coincident and error with rotating speeds
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
