Chaotic Scenario in Three-Component Fermi Plasma
(Abdus Salam International Centre for Theoretical Physics, 2020) Ghosh, T.; Pramanick, S.; Sarkar, S.; Dey, A.; Chandra, S.
Electron Acoustic Solitary structures in Fermi Plasma with two temperature electrons have various applications in space and laboratory-made plasmas. Formulation of an adequate theory is important to understand various physical systems with various physical parameters. The motion of two temperature electrons in a quantum Fermi plasma system highly affects the solitary profile of the system. We study the quantum Fermi plasma system with two temperature electrons where the streaming velocities of two-electron population are opposite. We consider quantum hydrodynamic model (QHD) and derive a linear dispersion relation for the system. For non-linear study of the system, we use standard perturbative technique to derive Kortewegde Vries Burger's equation and show the evolution of solitary profile with different plasma parameters. We analyse the stable Rouge wave structure using NLSE and show simulation results. We study the dynamical properties and phase plot for two-stream quantum Fermi plasma system with two temperature electrons. © 2020. All Rights Reserved.
Homotopy Study of Spherical Ion-Acoustic Waves in Relativistic Degenerate Galactic Plasma
(Institute of Electrical and Electronics Engineers Inc., 2022) Sarkar, S.; Sett, A.; Pramanick, S.; Ghosh, T.; Das, C.; Chandra, S.
In this work, we start with the ion-acoustic waves in galactic plasma with the degenerate matter. We use the reductive perturbation technique to derive the spherical Kadomtsev-Petviashvili (SKP) equation. We next employ homotopy-aided symbolic simulation (HASS) to study the evolution of the spherical solitary wavefront. We compare the results obtained by HPM and RPT. To understand how the system behaves, we transform the evolutionary equations into a dynamical system. The phase portraits and the superperiodic waves reflect on the intricate processes within the plasma and determine the stability criteria and possible situations of chaos. The work will find applications in many astrophysical observations, such as electrostatic wave modes, gamma-ray bursts, and double-layer solitons.

Load Scheduling Algorithm Design for Smart Home Energy Management System
(2018) Pawar, P.; Sampath, S.; Ghosh, T.; Vittal, K.P.
In a world of diminishing energy stores and heightening economic crises, it is imperative to develop systems that diminish our dependence on non-renewable resources. There is a growing trend of Smart Home Energy Management Systems (SHE) which use smart switches to actively monitor the energy consumption by each load, the power available and other factors to switch between renewable resources and the main power grid. An extensive literature survey was conducted and results of various approaches were consolidated and analyzed. The approach detailed is a combination of the merits of all the most popular approaches. The methodology proposed hopes to carry out demand response management on both the grid power and solar power in unison. The problem was split in two: scheduling assuming only solar power is available and scheduling assuming only grid power is available. The two halves are then merged together to have the most efficient utilization of the resources available. Further, after analysing the simulation results, the validity of such a solution is presented while adhering to various real world variables. � 2018 IEEE.
