[02055] EMinv software platform for comprehensive analysis of geoscience data

  • Session Time & Room : 3E (Aug.23, 17:40-19:20) @D407
  • Type : Contributed Talk
  • Abstract : We designed and developed a new software platform, consisting of processing and inversion modular for magnetotelluric data and visualization modular for all the geoscience results. New self-improved processing and inversion algorithms were applied in this platform. This platform unified the format of data, results and models and connected data processing, interpretaion and visualization, using our new rule and integrated standard. The platform is a useful tool for both production managers and scientific researchers.

[00240] Phantom cosmological model with observational constraints in symmetric teleparallel gravity

  • Session Time & Room : 3E (Aug.23, 17:40-19:20) @D407
  • Type : Contributed Talk
  • Abstract : The cosmological model of the Universe has been presented in symmetric teleparallel gravity and the parameters are constrained from the cosmological datasets. The nonmetricity function considered here contains higher power of the nonmetricity. With some algebraic manipulation the Hubble parameter has been obtained in redshift. The cosmological and geometrical parameters are obtained and constrained using the recent Hubble and Pantheon + SHOES datasets. The model shows early deceleration and late time acceleration.

[00043] Matter-chameleon coupling in reconstructed Brans-Dicke cosmology

  • Session Time & Room : 3E (Aug.23, 17:40-19:20) @D407
  • Type : Contributed Talk
  • Abstract : In the present work, we studied the generalized Brans-Dicke (BD) model with a scalar field non-minimally coupled with the matter sector. We considered extended holographic Ricci dark energy $\rho_{\Lambda}=3\phi (\alpha\dot{H}+\beta H^2)$ in this BD cosmology framework, derived restrictions for BD parameter $\omega$, and observed a stronger matter-chameleon coupling. The EoS parameter behaved like quintom. We observed an increasing potential function as matter-chameleon coupling gets stronger. Also, deceleration parameter transited from decelerated to the accelerated universe phase.
