Entrainment studies in cloud-like flows using novel scanning tomography technique
No full textClouds are one of the major sources of uncertainty in climate prediction.The present work is to study the dynamics of orographic clouds. We considered a planar turbulent wall jet with off source volumetric heating as an appropriate low order fluid-dynamical model for studying the turbulence and entrainment in orographic-clouds. Entrainment was found to reduce drastically with the off-source volumetric heat addition. We found that the reduction of entrainment started at a bulk-Richardson number which was an order of magnitude smaller than that seen in earlier experiments [1] on free standing cumulus clouds. This is consistent with observations in real orographic clouds which develop as a thin sheet rising along the mountain slope. We have developed a novel scanning tomography technique for getting concentration field in turbulent shear flows. This technique is being applied on cloud-like flow to understand the entrainment characteristics. Detailed results will be presented at the conference
Twenty K.R. Narayanan Orations
No full text"The Australia South Asia Research Centre (ASARC) was established in 1994 in one of the premier universities of the world—The Australian National University (ANU). Apart from its research and doctoral training activities, ASARC also needed a public forum with a global reach to involve the best minds working on economic development in India as well as to honour its founder, Dr K.R. Narayanan, President of the Republic of India. The K.R. Narayanan Oration series was developed in response to these twin needs.
The first oration was held in 1994 and the latest (the 20th) was held in 2018. The first 10 orations were published by ANU Press in 2006. This new edition updates the volume to include all 20 orations delivered so far and provides an updated introduction. All these orations have been delivered by leading academics, scientists and policymakers deeply involved in the transformation of the Indian economy.
This collection of the Narayanan Orations is thus at once both an expert account of key aspects of the economic development process in India and a peek into India's potential in the future. As such, the publication of this volume marks a watershed in the intellectual debate on India’s economic reforms program and should be welcomed by all those interested in the economic development of the country.
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
