This work studies how to estimate the mean-field density of large-scale systems in a distributed manner. Such problems are motivated by recent swarm control technique that uses approximations represent collective effect swarm, wherein (especially its gradient) is usually used feedback design. In first part, we formulate estimation problem as filtering associated partial differential equation (P...

The ill-posed problem of determining the shape of a body immersed in a ""at earth" and the mass density within this body from gravity anomaly measurements on the surface of the earth is investigated. Under some a priori assumptions on the structure of the body's boundary a general theorem on uniqueness of the solution is established and some further theorems are derived as immediate consequence...

The perturbative treatment of subdominant oscillation and matter effect in neutrino beams/superbeams, propagating over long baselines and being used to look for CP violation, is studied here for a general matter density function varying with distance. New lowest order analytic expressions are given for different flavour transition and survival probabilities in a general neutrino mixing basis an...

background: co-authorship is one of the most tangible forms of research collaboration. a co-authorship network is a social network in which the authors through participation in one or more publication through an indirect path have linked to each other. the present research using the social network analysis studied co-authorship network of 681 articles published in journal of research in medical...
