Research of the Chain Transmission System Dynamics of Heavy-duty Upender
No full textThe chain transmission system of heavy-duty upender is critical for turning body safe operation and parking,therefore,the reliability analysis of the chain transmission system is indispensable for the research and development of large heavy-load upender.Based on a nuclear large pieces upender which we jointly developed with a heavy machinery factory,the complex force state in the equipment operation process is analyzed.With the application of theoretical analysis and motion simulation method,the dynamic change trend of the chain transmission torque when carrying extreme load in the different flip solutions is got,the biggest stress field of the chain drive system is analyzed with the finite element software ABAQUS.The cost of research and development of the equipment is reduced,the design cycle is shorten,the reliability of equipment operation is improved,which has a certain reference value for the dynamics research of chain drive system in large and heavy equipment mechanics
ELASTICITY OF SUBSTITUTION BETWEEN LABOUR AND CAPITAL ACROSS TWENTY SIX MAJOR INDUSTRIES IN INDIA DURING 2004-05
Get PDFThe magnitude of the elasticity of substitution between labour and capital across twenty six major Industries [Factory Sector] in India has been estimated in the present paper by fitting a Constant Elasticity of Substitution Production Function for the year 2004-05.The empirical results emerged out of the cross section data demonstrate that the estimate of the elasticity of substitution between labour and capital across the major Indian Industries is significantly more than unity implying that substitution possibilities are rather more in favour of labour in the Indian major IndustriesIndustry, Production Function, India, Elasticity of Substitution, Economic Development
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
DEGREE OF TAX BUOYANCY IN INDIA : AN EMPIRICAL STUDY
Get PDFAn attempt is made in the present to provide an empirical content to differential coefficient of tax [revenue] buoyancy during post tax reform period in India by fitting a double-log regression model with an interaction variable to the stationary time series data based on Augmented - Dicky Fuller [ ADF ] and Phillips-Parron [PP] Tests . The period after 1992 is considered as post tax reform period to look at the prognostications of tax reforms that had been initiated by the government of India. The regression results illustrate that the estimate of constant gross tax buoyancy is positively significant and more than unity during pre tax reform period illuminating that gross tax is moderately elastic. From this upshot it can be comprehended that a one percent increase in income leads to increase the gross tax revenue by more than one percent, all else equal. Further it can be understood that the average propensity to tax [ratio of Gross Tax Revenue to Gross Domestic Product ] was increasing with the increase in Gross Domestic Product during pre tax reform period. The regression coefficient of interaction variable is significantly negative and stumpy showing a downward shift in the degree of tax buoyancy during post tax reform period. The estimate of the tax buoyancy, which was just above the unity during pre tax reform period, is less than unity during post tax reform period evincing the fact that the gross Tax is relatively inelastic. From this it can also be understood that the average propensity to tax is declining with the increase in Gross Domestic Product during post tax reform period. Thus the estimates of gross tax buoyancy during pre and post tax reform periods are not stable.
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
A dense definition of Rūpaka. What does Rūpyate mean in Bhāmaha's Kāvyālaṃkāra 2.21?
No full textThis paper takes into account the definition of the complex metaphor (ai. rūpaka) on the basis of Bhāmaha's definition (Kāvyālạ̜kāra 2.21). It involves the verbal form rūpyate, which is not so common in Sanskrit texts, while it is clearly focused on by the Buddhist tradition, in particular by Vasubandhu. A fresh proposal of interpretation of this rhetorical definition is thus advanced
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
