Bondability of ultrasonic Aluminum bonds on the molybdenum (de) selenide and molybdenum of back contact layer of copper indium gallium (de)selenide GIGS thin film photovoltaic solar panel
No full textThis paper aims to study the bondability of ultrasonic Aluminum, Al bonds on Mo and MoSe2 layers of back-contact metal of copper indium gallium (de)selenide (CIGS) thin film photovoltaic (TFPV) solar panel. The bondability of ultrasonic Al bonds were evaluated based on the contact resistance, R-c, peel strength and electrical characteristics measured using transmission line method (TLM), peel test, and current-voltage (I-V) measurement, respectively. Besides, the qualitative results of load-distance profiles from tensile test also have been used to evaluate the bondability of the ultrasonic Al bonds. Two type of lamination constructions namely construction 1 and construction 2 were built on the CIGS TPFV solar panel with ultrasonic Al bonds on Mo and MoSe2. It was noted that the new method of removing CIGS layer up until MoSe2 is the plausible technique to be used. Ultrasonic Al bond on Mo layer has higher bondability as compared to that of ultrasonic Al bond on MoSe2 through the quantitative results of R-c, peel strength and qualitative result of load-distance profile. CIGS TFPV solar panel with construction 2 is the suitable construction for the CIGS TFPV solar panel due to the higher rigidity, and even stress distribution experienced during lamination process as compared to that of construction 1. It is noted that steps taken from ultrasonic bonding until lamination process has increased the cumulative contact area and decreased the R-c and consequently increased the efficiency of CIGS TFPV solar panel with ultrasonic Al bond on MoSe2 layer.This work was sponsored by Ministry of Higher Education of Malaysia under the Fundamental Research Grant Scheme (FRGS/1/ 2020/TKO/UNIKL/02/10) and Universiti Kuala Lumpur under Short

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
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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
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
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
1D photonic crystal nanocavities for optical sensing
No full textThe ability to detect small refractive index changes in analytes is of uttermost importance since these index changes can be directly correlated to the presence of small amounts of chemicals of interest within analytes. Photonic devices such as 1D PhC nanocavities are one of the interesting structures to be used as optical sensors due to their capability to integrate with CMOS technology. We present in this study, a simple optical technique of detection based on 1D PhC nanocavities that gives good sensitivity for various types of chemicals. The work reported in this thesis concerned with the designed, fabrication, and characterisation of 1D PhC nanocavity devices based on silicon-on-insulator (SOI) material. The objective of this work is to provide an optical wave-guided sensing technology using 1D PhC nanocavity devices in the wavelengths region around 1550 nm. Firstly, the PhC nanocavities were designed and modelled using 2D and 3D Finite-difference time-domain (FDTD) computations to provide insight behaviour of the resonator waveguides. The designated PhC nanocavity devices were carefully fabricated via combination of electron beam lithography (EBL) and the dry and wet etching technology. The nanocavity devices were realised using optimised fabrication process to ensure the sensing chips are reproducible and reliable. This is done by careful control at nanometre scale of fabrication process of the PhC nanocavity devices and the microfluidic chip. Then, the devices were paired with the PDMS based microfluidic channel system. The nanocavity devices were characterised and the sensor system were tested for their optical sensing capabilities. The sensitivity of various Q factor values corresponds to the different cavity lengths are studied. The sensor system sensitivity, S were measured via refractive index sensing experiment varying from 135.78 to 245.72 nmRIU-1 with the detection limit, DL of 8 x 10-6 RIU. The sensing area estimated is 2.35 μm2. In addition, through the non-specific interaction experiment, bio molecular proteins BSA as low as 3.125 μg/ml concentrations were detected. Finally, the sensor system thermal responses were measured
