Study of participant-spectator matter, thermalization and other related phenomena for neutron-rich colliding pair

We study the participant-spectator matter, density and temperature reached in heavy-ion reactions of neutron-rich systems having N/Z varying from 1.0 to 2.0 at 50 and 250 MeV/nucleon. The N/Z dependence of these quantities is also investigated. Our results show a weak dependence on the N/Z ratio of the system on these quantities. We also shed light on the role of N/Z ratio on the thermalization achieved in a reaction. We find similar weak N/Z dependence on thermalization also.Comment: 14 pages, 6 figure

Multi-time-horizon Solar Forecasting Using Recurrent Neural Network

The non-stationarity characteristic of the solar power renders traditional point forecasting methods to be less useful due to large prediction errors. This results in increased uncertainties in the grid operation, thereby negatively affecting the reliability and increased cost of operation. This research paper proposes a unified architecture for multi-time-horizon predictions for short and long-term solar forecasting using Recurrent Neural Networks (RNN). The paper describes an end-to-end pipeline to implement the architecture along with the methods to test and validate the performance of the prediction model. The results demonstrate that the proposed method based on the unified architecture is effective for multi-horizon solar forecasting and achieves a lower root-mean-squared prediction error compared to the previous best-performing methods which use one model for each time-horizon. The proposed method enables multi-horizon forecasts with real-time inputs, which have a high potential for practical applications in the evolving smart grid.Comment: Accepted at: IEEE Energy Conversion Congress and Exposition (ECCE 2018), 7 pages, 5 figures, code available: sakshi-mishra.github.i

Isospin effects on the system size dependence of balance energy in heavy-ion collisions

We study the effect of isospin degree of freedom on balance energy throughout the mass range between 50 and 350 for two sets of isobaric systems with N/A = 0.5 and 0.58. Our fndings indicate that different values of balance energy for two isobaric systems may be mainly due to the Coulomb repulsion. We also demonstrate clearly the dominance of Coulomb repulsion over symmetry energy.Comment: EFB 2010, August29-september03, 2010 Salamanca, SPAI
