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
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

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Comparison of anaerobic digestion of various food and non-food wastes: impact of inoculum source on biogas production
No full textThis study investigated how the inoculum source and type of organic waste influence biogas production, removal of various pollutants, and chemical parameters under thermophilic conditions at 55 °C. The three inoculum sources evaluated were horse manure (HM), cattle manure (CM), and municipal sewage sludge. The study evaluated the biochemical methane potential (BMP) of several substrates including food waste (FW), orange peel (OP), coffee grounds (CG), duckweed (Lemna gibba) (DW), and seagrass (SG). The results indicated differences in biogas production depending on the inoculum used. With horse manure, the highest yield was obtained by DW, producing 4549.87 ml of biogas per gram of total volatile solids (TVS). Using DW with CM had a maximum production of 7423.05 ml/g of TVS, while using anaerobic sludge as inoculum consistently produced the least biogas with all substrates. The study also evaluated the removal efficiency of various parameters including COD, TS, TVS, NH4+ and TKN. Finally, the estimated kinetic parameters for the biogas production potential and rates were discussed using the first order model and the modified Gompertz model, and found that the modified Gompertz plot had a higher correlation than the first-order model with the maximum plot to simulate the biogas accumulation production

Development of a virtual reality milling machine for knowledge learning and skill training
No full textCurrent methods of training personnel on high cost machine tools involve the use of both classroom and hands on practical training. The practical training required the operation of costly equipment and the trainee has to be under close personnel supervision. The main aim of this project is to reduce the amount of practical training and its inherent cost, time, danger, personal injury risk and material requirements by utilising a virtual reality technology.
In this study, an investigation into the use of Virtual reality for training operators and students to use the Milling Machine was carried out. The investigation has been divided into two sections: first the development of Milling Machine in the 3D virtual environment, where the real machine was re-constructed in the virtual space.
This has been carried out by creating objects and assembling them together. The complete Milling machine was then properly modelled and rendered so it could be viewed from all viewpoints.
The second section was to add motion to the virtual world. The machine was made of functions as for the real machine. This was achieved by attaching Superscape Control Language (SCL) to the objects. The developed Milling machine allows the users to choose the material, speed and feed rate. Upon activation, the virtual machine will be simulated to carry out the machining process and instantaneous data on the machined part can be generated.
The results were satisfactory, the Milling Machine was modelled successfully and the machine was able to perform according to task set. Using the developed Virtual Model, the ability for training students and operators to use the Milling Machine has been achieved

O-Blue for Outlier Tests
No full textThe O-BLUEs defined by Moussa-Hamouda and Leone(1974) are considered and the effect of an outlying observation in these estimates are studied for a regression model. Then these estimates are used in developing two outlier test procedures. The results are highlighted with an example. The power of these procedures are studied and the power values for the same example are also tabulated
