Raga recognition using fibonacci series based pitch distribution in Indian Classical Music

Sinith, M. S.; Tripathi, Shikha; Murthy, K. V. V. (Elsevier, 2020-10)

Fibonacci Series and Music are related in many ways. Even though Indian Classical Music (ICM) is known to be based on Just Intonation rather than equal tempered, not much attention has been given to inflections on the ...
Rapid Tracking of Grid Variables Using Prefiltered Synchronous Reference Frame PLL

Subramanian, Chandrasekaran; Ragavan, K. (IEEE, 2015-07)

For synchronization applications, synchronous reference frame (SRF) phase-locked loop (PLL) is widely deployed. Its performance is excellent when the input voltage consists of only fundamental positive sequence (FPS) ...
A real time control strategy for improvement of autonomous operation in AC/DC micro grids using electric springs

Cherukuri, S. Hari Charan; Kuhada, Ravindra B.; Kachhad, Vishal M.; Pindoriya, Naran M. (Wiley, 2020-10)

The work presented in this article proposes a new centralized control strategy for energy management in grid interactive hybrid micro grids using AC and DC electric springs based on the available generation. The planned ...
A reduced complexity random fourier filter based nonlinear multichannel narrowband active noise control system

Deb, Trisrota; Ray, Dwaipayan; George, Nithin V. (Institute of Electrical and Electronics Engineers, 2021-01)

Linear-in-the-parameters nonlinear controllers are widely used for active noise cancellation (ANC) in the presence of nonlinearities in the system. However, the performance of such controllers deteriorates significantly ...
Reference Current Extraction through Sliding DFT Assisted Single Phase p-q Theory for Shunt Active Power Filter

Chandrasekaran, S.; Ragavan, K. (De Gruyter, 2013-05)

Abstract: Active Power Filters (APF) are more effective than conventional passive filters with regard to mitigating harmonics and compensating reactive power. As a result, deployment of APF in the distribution network is ...
Reflection symmetry axes detection using multiple model fitting

Nagar, Rajendra; Raman, Shanmuganathan (IEEE, 2017-10)

We propose an energy minimization approach to detect multiple reflection symmetry axes present in a given image representing fronto-parallel view of a scene. We perform local feature matching to detect the pairs of mirror ...
Remotely sensed high resolution irrigated area mapping in India for 2000 to 2015

Ambika, Anukesh Krishnankutty; Wardlow, Brian; Mishra, Vimal (Nature publishing group, 2016-12)

Revealing hidden 3D reflection symmetry

Nagar, Rajendra; Raman, Shanmuganathan (IEEE, 2016-12)

Reflection symmetry is present in most of the man-made or naturally formed objects. In computer vision, real-world scenes are represented by dense 3-D models or by 2-D projections, such as images captured by cameras. Most ...
Risk?constrained optimal bidding strategy for a wind power producer with battery energy storage system using extended mathematical programming

Abhinav, Rishabh; Pindoriya, Naran M. (Institution of Engineering and Technology (IET), 2021-01)

Wind power producers (WPP) in India, currently, are restricted from participating in the short?term energy market due to the uncertainty in their power generation. Consequently, they might lose an excellent opportunity to ...
