Artificial neural network based modelling approach for municipal solid waste gasification in a fluidized bed reactor

no code implementations5 Feb 2018 Daya Shankar Pandey, Saptarshi Das, Indranil Pan, James J. Leahy, Witold Kwapinski

In this paper, multi-layer feed forward neural networks are used to predict the lower heating value of gas (LHV), lower heating value of gasification products including tars and entrained char (LHVp) and syngas yield during gasification of municipal solid waste (MSW) during gasification in a fluidized bed reactor.

Performance Analysis of Robust Stable PID Controllers Using Dominant Pole Placement for SOPTD Process Models

no code implementations28 Jan 2018 Saptarshi Das, Kaushik Halder, Amitava Gupta

The effect of different types of non-dominant poles and the corresponding stability regions are obtained for nine test-bench processes indicating different levels of open-loop damping and lag to delay ratio.

Evolving Chaos: Identifying New Attractors of the Generalised Lorenz Family

no code implementations28 Jan 2018 Indranil Pan, Saptarshi Das

In a recent paper, we presented an intelligent evolutionary search technique through genetic programming (GP) for finding new analytical expressions of nonlinear dynamical systems, similar to the classical Lorenz attractor's which also exhibit chaotic behaviour in the phase space.

Multi-objective Active Control Policy Design for Commensurate and Incommensurate Fractional Order Chaotic Financial Systems

Fractional Order AGC for Distributed Energy Resources Using Robust Optimization

no code implementations29 Nov 2016 Indranil Pan, Saptarshi Das

The applicability of fractional order (FO) automatic generation control (AGC) for power system frequency oscillation damping is investigated in this paper, employing distributed energy generation.

Fractional Order Load-Frequency Control of Interconnected Power Systems Using Chaotic Multi-objective Optimization

no code implementations29 Nov 2016 Indranil Pan, Saptarshi Das

The chaotic versions of the NSGA-II algorithm are compared with the standard NSGA-II in terms of solution quality and computational time.

Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques

no code implementations20 Oct 2014 Valentina Bono, Wasifa Jamal, Saptarshi Das, Koushik Maharatna

In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and Independent Component Analysis (ICA).

Classification of Autism Spectrum Disorder Using Supervised Learning of Brain Connectivity Measures Extracted from Synchrostates

no code implementations20 Oct 2014 Wasifa Jamal, Saptarshi Das, Ioana-Anastasia Oprescu, Koushik Maharatna, Fabio Apicella, Federico Sicca

The minimal and maximally occurring synchrostates for each subject are chosen for extraction of brain connectivity features, which are used for classification between these two groups of subjects.
