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
Connected multisensory room with data analytics for cognitive impairment therapy/ Muhammad Akmal Jamil
Full text linkMultisensory room (MSR) is a prescription of therapy sessions for stimulating senses involving patient and therapist interaction. Therapy sessions are known to take effect at different rate depending on patient’s condition and response, often across a long period of time for it to be noticeable. Based on this reason, there is a need to improve data collection and analysis that will allow clinical data analytic. This project presented a multisensory room design that offers added connectivity for data storage and configuration for data analytics. The main objective is to develop effective data collection through multisensory therapy session. Second objective is to demonstrate data analytics using predictive model towards data collected from the multisensory room. Under this framework, the therapy would be divided to five sub-modules. First, when the patient meets the doctor or therapist assessment, to be given the clinical prescription. Second is therapist assessment, followed by the MSR session, then the post-MSR therapist assessment. The treatment is concluded by data analytics. MSR performed analysis to assist doctor’s review of the prescribed MSR using artificial data that is incorporated into behavioural checklist and patient data. Results show that in a connected environment of a multisensory room, data analytics involving visual representation and linear regression predictive model using SAS Viya is able to produce patient response analysis. The analysis will be useful to support doctor’s assessment of the patients that have undergone therapy sessions
Perancangan Sistem Propulsi Diesel-Elektrik pada Kapal Penyeberangan Ujung Surabaya - Kamal Madura
No full textPenyebrangan Ujung Surabaya-Kamal Madura merupakan akses transportasi utama penghubung Pulau Jawa dengan Pulau Madura. Namun sejak berdirinya jembatan Suramadu pada tahun 2009 penyebrangan Ujung-Kamal tidak lagi menjadi satu-satunya akses penghubung antar pulau. Hal itu menyebabkan penurunan pengguna jasa dan kerugian perusahaan penyebrangan sebab biaya operasional kapal yang tinggi terutama pada bahan bakar. Maka penelitian ini dilakukan untuk dapat mengurangi biaya operasional bahan bakar kapal pada penyebrangan Ujung —Kamal dengan melakukan penyesuaian dimensi kapal, merancang sistem propulsi diesel mekanik dan diesel-elektrik pada kapal feri, dan membandingkan biaya bahan bakar kedua sistem. Penelitian dilakukan melalui pendekatan desain kuantitatif berdasarkan acuan data lapangan. Hasil penelitian didapatkan ukuran kapal yang optimal dengan dimensi utama LPP 20.6 m, LWL 20.68 m, B 5.18 m, T 1.22 m, H 2.29 m, Cb 0.75, Cp 0.838, Displasmen 100 Ton, payload 19.35 Ton, dengan kecepatan 7 Knot. Sistem propulsi diesel mekanik dirancang menggunakan 2 unit mesin diesel AII VETUS M4.35 berdaya 24.3 KW, gearbox Reintjes DLG series rasio 5.06, dan propeller B4-100 berdiameter 0.6869 m. Sedangkan sistem propulsi diesel-elektrik menggunakan 2 unit motor listrik ABB M3BP 180MLB4 berdaya 22 KW, gearbox Reintjes rasio 2.6, propeller B4-100 berdiameter 0.6869 m, dan menggunakan generator Sole Diesel 25GT/GTC berdaya 19.5 KW sejumlah 5 set. Pada pola operasional penyebrangan Ujung-Kamal penggunaan sistem propulsi diesel-elektrik dengan ukuran kapal yang sudah disesuaikan dapat menghemat biaya bahan bakar sebesar 51.68% dibandingkan dengan penggunaan sistem propulsi diesel mekanik.

The Surabaya-Kamal Madura Crossing is the main transportation access connecting Java Island with Madura Island. However, since the establishment of the Suramadu bridge in 2009, the Ujung-Kamal crossing is no longer the only connecting access between the islands. This has led to a decrease in service users and losses from crossing companies due to high ship operating costs, especially in fuel. Therefore, this study was carried out to be able to reduce the operational cost of ship fuel at the Ujung -Kamal crossing by adjusting the dimensions of the ship, designing a mechanical diesel and diesel-electric propulsion system on the ferry, and comparing the fuel costs of the two systems. The research was conducted through a quantitative design approach based on field data references. The results of the study obtained the optimal size of the ship with the main dimensions of LPP 20.6 m, LWL 20.68 m, B 5.18 m, T 1.22 m, H 2.29 m, Cb 0.75, Cp 0.838, 100 Tons Displacement, 19.35 Tons payload, with a speed of 7 knots. The mechanical diesel propulsion system is designed using 2 units of AII VETUS M4.35 diesel engine with a power of 24.3 KW, a Reintjes DLG series gearbox with a ratio of 5.06, and a B4-100 propeller with a diameter of 0.6869 m. Meanwhile, the diesel-electric propulsion system uses 2 units of ABB M3BP 180MLB4 electric motors with a power of 22 KW, a Reintjes gearbox with a ratio of 2.6, a B4-100 propeller with a diameter of 0.6869 m, and uses a 25GT/GTC Sole Diesel generator with a power of 19.5 KW for a total of 5 sets. In the operational pattern of the Ujung-Kamal crossing, the use of a diesel-electric propulsion system with an adjusted ship size can save fuel costs by 51.68% compared to the use of a mechanical diesel propulsion system
Study on the Effect of Syngas Fuel Temperature to the Performance of a Small-Scale Electrical Power Generator.
No full textGasification of various types biomass to produce producer gas or syngas as alternative energy source has been widely researched with the aim to reduce greenhouse gases emission as well as reducing the dependency to fossil fuel. One of the main promising applications of syngas produced from gasification is for power generation, which is one of the objectives of this study by varying the syngas temperature supplied to a small-scale electrical power diesel generator. This is because syngas temperature flowing out of the gasifier is always quite high, hence the need to cool the syngas down, increasing capital cost. The objective of this study was to investigate the effect of the varying syngas temperature supplied to the performance of the diesel generator. The feedstock used as the gasifier fuel is wood chips, and the syngas produced was cleaned by a wet scrubber. The temperature of the syngas was controlled by controlling the amount of water pumped into the gas cleaning system. The electrical generator performance is analyzed through the diesel consumption rate of the generator’s engine and the stable power output of the generator
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
