MENGEVALUASI PENGHAWAAN ALAMI SEBUAH RUMAH TROPIS DUA LANTAI DENGAN MENGGUNAKAN TEKNIK SIMULASI NUMERIK
No full textLarge openings in tropical style houses are needed to get enough airflow through the rooms. As it is mentioned In the Indonesian standard building (SK SNI T-14-1993) that there is a minimum ventilation rate for each room. This study concern in evaluation of natural ventilation performance of a two-story tropical house in Manado. Recently, numerical simulation is common method and practical tool in the researches in engineering. Airflow pattern in buildings can easily evaluated using numerical simulation method. Wind direction and speed as variable of inputs can easily varied and introduced in the code of simulation. In this study a computer program Ventila.1.0 (written by Sangkertadi, 1998) is used as simulator. This code is based on the basic of flow equations (Bernoulli, Pressure difference, Stack-effect, Mass balance). The results show that the quantity of airflow from cross ventilation is greater than the minimum value mentioned in the standard. Abstract in Bahasa Indonesia : Tipe rumah tropis pada umunya adalah memiliki bukaan cukup untuk menghasilkan debit ventilasi untuk mencapai tingkat kenyamanan dan kesehatan ruang. Namun begitu yang dijadikan ukuran mengenai persyaratan kuantitas debit ventilasi di Indonesia telah ditetapkan melalui SK SNI-T-14-93. Studi ini adalah dalam rangka mengevaluasi sistim penghawaan alami pada sebuah tipe rumah tropis berlantai dua (merupakan modifikasi dari rumah tradisional Minahasa) yang berada di daerah perkotaan (di pusat kota di Manado). Rumah tersebut dibuat sedemikian sehingga terdapat sebuah ciri ventilasi cerobong disalah satu bagian ruangannya. Metoda yang dipakai dalam studi ini adalah simulasi numerik dengan program Ventila.1.0 (program dibuat oleh Sangkertadi, 1989, dalam bahasa Fortran77) Formulasi yang ada didalam program ini didasarkan pada persamaan-persamaan umum tentang aliran (Bernoulli, Perbedaan Tekanan, Stack Effect, dll). Hasil dari simulasi menunjukkan bahwa ternyata sistim penghawaan silang berlangsung dengan baik dan nampak bahwa sistim ventilasi cerobong juga menunjukkan fungsinya dengan baik.

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
