Reaching the Unreached: Community Based Village Knowledge Centres and Village Resources Centres
No full textThe book explores the history, initiatives and achievements of the M. S. Swaminathan Research Foundation (MSSRF). These include the bio-village initiative, designed to encourage the development of market driven on-farm and non-farm enterprises, and unskilled to skilled work through the sustainable use of natural resources; as well as the Village Through the VKCs (Village Knowledge Centres). The aim is to bridge the digital divide and thus address social exclusion and poverty associated with it. Through Village Resource Centres and VKC information and technology communication for development (ICT4D) strategies many communities in India have been positively impacted
Loading on a vertical cylinder near mean water level in long-and-short-crested waves
No full textThis paper presents the results of an experimental investigation on wave forces on a vertical cylinder in the splash zone. The cylinder was subjected to long- and short-crested waves corresponding to JONSWAP spectra, and sectional loads were measured on force sleeves up to mean water level. Ambient particle velocities were measured by means of perforated ball velocity metres whose performance in intermittent flow was checked with reference to a Laser Doppler Anemometer. Maximum Keulegan-Carpenter numbers were about 24, and maximum Reynolds numbers about 8.5 x 104. Analysis of the measurements concentrated on determining the effect of wave directionality on loading at mean water level. Comparison with earlier results for the submerged part of the cylinder suggests that in the splash zone directionality leads to stronger attenuation of loading than at lower elevations. The changes in loading are rather greater than those predicted by Dean's (1977) hybrid theory
Loading on a vertical cylinder in multidirectional waves
No full textThis paper presents laboratory measurements of local and total loading on an isolated vertical cylinder in irregular unidirectional and multidirectional waves. Maximum Keulegan-Carpenter numbers in individual waves were about 16, and maximum Reynolds numbers about 3 × 104. It is shown that in these conditions, existing theoretical and numerical models underestimate the reduction in loading on a cylinder due to wave spreading. Besides the changes that are predicted when Morison's equation is used with constant coefficients, there are hydrodynamic influences that contribute further force reductions. Comparisons with Dean's (1977) hybrid approach suggest that in the present conditions these reductions are in the region of 3 and 6 percent for a spreading function cos2s , with s = 8 and s = 2, respectively. Larger reductions can be expected at higher Keulegan-Carpenter numbers, though scale effects are likely to become more important in the drag-dominated regime
Local forces on a vertical cylinder in regular and irregular waves
No full textThis paper presents results from an experimental investigation on the loading on a rigid slender vertical circular cylinder in undirectional regular and irregular waves. The ambient flow was measured directly, so that the derived results would not be subject to additional uncertainties associated with the use of wave theories. Morison drag, inertia and lift coefficients are computed from forces measured at one force sleeve and compared with data obtained at the same Reynolds and Keulegan Carpenter numbers, but under uniform flow conditions in a U-tube. In regular waves, the results show the importance of the non-uniformity of wave-induced flow, and in irregular waves it is clear that the loading is much influenced by the history of the flow.NRC publication: Ye

An Application of Transformed Distribution: Length of Stay in Hospitals
No full textLength of stay in hospitals are mostly characterized as asymmetric, right skewed and leptokurtic in nature. Earlier studies have considered parametric distributions like gamma, Pareto, lognormal for studying length of stay of patients in hospitals. However, in this study we have proposed transformed distributions to be the best choice for characterizing the length of stay. For this study, we have considered paediatric asthma dataset and identified that transformed Weibull-Pareto as the best fit. For a comparative purpose we have also provided the results of gamma, lognormal, and Pareto distributions. Maximum likelihood approach is considered to estimate the unknown parameters of the Transformed distribution followed by goodness of fit tests to examine the suitability of the fitted distributions. The results provide a direction for modelling the length of stay in hospitals due to different medical problems which require hospitalization

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
