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
Investigation the effect of neutral current and harmonic at laboratory building
No full textAccess is limited to UniMAP community.This project is aimed to study and identify power quality related neutral current
and harmonics effects in the Muhibah laboratory building. In this project, it will analyze
the quality of the power distribution board in which supply power to the laboratory
equipment. The equipment that use along the monitoring is Three Phase Power Recorder
(Fluke 1750) to obtain an overview of the resulting waves throughout the analysis
performed. From the resulting waveforms, the analysis will be made to identify the
quality level of power that occurred in the laboratory building is mainly related to the
input is not stable especially that related on harmonics and non-linear loads occurs. This
project mainly to monitoring and investigate power quality problem occur at the
building. The available of lab contained with the linear load and non linear load
(lighting system, air-conditioner system, computer, measurement meter etc.) in the
building make contribution of power quality problem others than incoming power
problem from provider. In this final year project, a study of neutral currents in threephase
distribution network with non-linear loads is presented. Studies show that the
magnitude of the neutral current in three-phase computer power systems depends on the
harmonic content and phase balance of the load currents. Power system problems
associated with high harmonic neutral currents include overloaded four-wire power
feeders and branch circuits, overloaded transformers, voltage distortion, and common
mode noise. Whenever three-phase, wye power systems are used to supply power to
computer systems, the power system design should allow for the possibility of high
harmonic neutral current to avoid potential problems. All the objective of this final year
project has been achieved. To prove the theory, the monitoring of non-linear three-phase
supplying single phase loads has been done. From the monitoring result, there has been
approving that neutral conductor of non-linear load has a lot of neutral current
The effect of power quality problem due to unbalance load at LV distribution system
No full textAccess is limited to UniMAP community.This report proposes the effect of power quality problem due to unbalance load at
LV distribution system. This project aims to monitor, investigate and analyze the power
quality problem due to unbalance load at selected UniMAP’s building which is school of
Material Engineering. In this research, voltage, current and signal were reviewed and been analyzed to find the cause of power quality problem and some recommendation to mitigate the power quality problem by using Fluke 1750 Power Recorder. The analysis of power
quality monitoring during the project progress was concerns in few section analyses which
is power, power factor, and neutral current analysis. From the analysis, highest power factor
is 0.998 and the lowest power factor is 0.016. The high power factor is better because low
power factor can sometimes cause equipment to fail. From the analysis of neutral current,
the highest value is 37.69A at 10.00am due to unbalance load because of the high uses of
equipment. While and the lowest value of neutral current is 1.33A at 7.00pm because of all
equipments are turned off. If the system is balanced, neutral current should be less or
approximately zero. School of Material Engineering’s building had the power quality
problem due to unbalance load. To overcome it, load should be distributed back to balance
the system
Design and analyze different topologies of multilevel inverter
No full textAccess is limited to UniMAP community.Conventional inverters have limitation in high voltage and high power applications. Lately, multilevel inverters are popular for high power applications due to its improved harmonic profile and increased power ratings. There is a lot of literature regarding the topology and control techniques of multilevel inverters. Thus the purpose of this project is to analyze and compare the performance between three multilevel inverter topologies of a 7, 9, 11 level multilevel inverter. Simulation studies on the operation of the multilevel inverter are done using the PSIM9 software. Analyses on the performance of the three topologies are based on the fundamental voltage, output voltage waveform, output current waveform and total harmonic distortion (THD). The general concept of a multilevel inverter is to synthesize a sinusoidal voltage from several levels of voltages. By having more than two levels to build the sinusoidal voltage, harmonic distortion of the waveform is significantly minimized
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
