ANALISIS TEKANAN ALIRAN PADA SISI HISAP POMPA PRIMER RSG-GAS
No full textANALISA TEKANAN ALIRAN PADA SISI HISAP POMPA PRIMER RSG-GAS. Kondisi tekanan pada sisi hisap pompa pendingin primer RSG-G AS merupakan parameter penting dalam pengoperasian sistem pendingin. Parameter tekanan ini memiliki karakteristik yang perlu diperhatikan. Teori yang terkait dengan tekanan aliran ini adalah sifat fisik dan termodinamika pendingin yang mencakup hubungan temperatur-tekanan, rugi tekanan aliran, dan sifat termodinamika sistem uap-air. Makalah ini bertujuan menganalisis hubungan antara tekanan dan temperatur pada aliran pendingin sisi hisap pompa primer. Metoda yang digunakan adalah menarik kurva saturasi dari diagram termodinamika air dan mengevaluasi data untuk mendapatkan kondisi operasi normal. Hasilnya menunjukkan bahwa batas tekanan rendah (-)0,15 bar (mengakibatkan kavitasi) bilamana temperatur pendingin dari teras reaktor mencapai 52oC. Untuk itu dengan mempertimbangkan aspek keselamatan reaktor, pengoperasian sistem pendingin yang aman harus menghindari garis kurva saturasi diantaranya dengan cara menurunkan temperatur atau mengurangi rugi tekanan alira

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
ANALISIS VIBRASI PADA POMPA PENDINGIN PRIMER JE01 AP003
Get PDFPompa pendingin primer JE01 AP003 merupakan salah satu komponen utama pada keselamatan operasi reaktor sehingga perlu dilakukan deteksi awal jenis dan tingkat kerusakan komponen penyusunnya. Komponen utama dari pompa yang sering mengalami kerusakan adalah bearing. Salah satu indikasi bearing telah mengalami kerusakan yaitu adanya vibrasi atau kenaikan suhu pada bearing. Tujuan dari penulisan ini adalah untuk mengetahui gejala kerusakan bearing dan tingkat kerusakannya berdasarkan analisis vibrasi. Salah satu cara untuk mendeteksi awal gejala kerusakan pompa adalah dengan mengetagui respon vibrasi hasil pengukuran dengan vibration tester. Berdasarkan analisis vibrasi akan diperoleh cited peak pada arah radial, aksial dan tangensial. Dari hasil analisis vibrasi tersebut maka dapat ditentukan gejala kerusakan pada free end bearing pompa pendingin primer JE01AP003 berupa looseness dengan tingkat kerusakan moderate sehingga perlu dilakukan penggantian bearing JE01 AP003 meskipun kerusakan yang terjadi belum parah.Abstract VIBRATION ANALYSIS OF PRIMARY AIR PUMP JE01 AP003. JE01 AP003 primary coolant pump is one of the main components in the safe operation of the reactor so that needs to be done early detection of damage types and levels of its constituent components. The main components of the pump that is often damaged bearing. The purpose of this paper is to know the symptoms of bearing damage and the level of damage based on vibration analysis. One indication of the bearing has been damaged, that is the vibration or temperature rise in the bearing. One way to detect early symptoms of damage to the pump is to use the vibration response peak Based on the analysis of the measurement results cited the obtained results that the primary coolant pump JE01 AP003 has been damage to a free end looseness bearing with moderate levels of damage. Need JE01 AP003 bearing replacement even though the damage is not severe
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
