Optical Spectroscopy for Biomedical DiagnosisProceedings of the National Academy of Sciences, India Section A: Physical Sciences - Tập 88 - Trang 453-460 - 2018
M. K. Swami, P. K. Gupta
In the last few decades there has been a remarkable growth in the development of optical spectroscopic techniques for in situ, sensitive, minimally invasive diagnosis. In this article we provide an overview of the field and highlight some representative applications. Special emphasis has been placed on the use of optical spectroscopic techniques for non-invasive diagnosis of cancer where a signif...... hiện toàn bộ
Control of Chaos to Obtain Periodic Behaviour via Nonlinear ControlProceedings of the National Academy of Sciences, India Section A: Physical Sciences - Tập 85 Số 1 - Trang 143-148 - 2015
Khan, Mohammad Ali, Sahoo, Banshidhar, Mondal, Arun Kumar
In this paper, we propose a scheme for controlling chaotic Lorenz like system to a periodic system via nonlinear control. Our method is based on Lyapunov stability theory. We have presented the numerical simulation results to show the efficiency of our method.
Laser Materials Processing for Industrial ApplicationsProceedings of the National Academy of Sciences, India Section A: Physical Sciences - Tập 88 - Trang 359-374 - 2018
G. Padmanabham, Ravi Bathe
Laser, a high intensity, precise, flexible and clean heat source is used as a manufacturing tool in several industrial sectors. With the advent of more robust, energy efficient, cheaper and low footprint lasers such as fiber lasers, laser based manufacturing is increasing rapidly. Laser based processes can be classified into macro processes (cutting, welding, cladding, alloying, drilling, brazing)...... hiện toàn bộ
Marangoni Convection in a Relatively Hotter or Cooler Liquid LayerProceedings of the National Academy of Sciences, India Section A: Physical Sciences - Tập 82 - Trang 103-106 - 2012
A. K. Gupta, R. G. Shandil
The onset of cellular convection induced by surface tension gradients on a thin layer of liquid as developed by Pearson (J Fluid Mech 4: 489–500, 1958[6]) is examined in the extended framework of Banerjee et al. (J Math Phys Sci 17: 603–629, 1983[11]). Numerical results are obtained for both the thermally conducting and insulating cases of the lower boundary surface. It is found that irrespective ...... hiện toàn bộ

Approximation by Integral form of Jain and Pethe OperatorsProceedings of the National Academy of Sciences, India Section A: Physical Sciences - Tập 92 - Trang 31-38 - 2020
Naokant Deo, Ram Pratap
In this paper, we consider the integral form of Jain and Pethe operators associated with the Baskakov operators and study some basic properties. We estimate the rate of convergence, Voronovskaja-type asymptotic estimate formula and weighted approximation of these operators.
