Exploring non-adiabatic approximations to the exchange-correlation functional of TDDFT
(Royal Society of Chemistry, 2018-09)
A decomposition of the exact exchange-correlation potential of time-dependent density functional theory into an interaction component and a kinetic component offers a new starting point for non-adiabatic approximations. ...
Rho-nucleon tensor coupling and charge-exchange resonances
(Elsevier B.V., 2000-11-23)
The Gamow-Teller resonance in Pb-208 is discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau-Migdal force ...
Heat transfer and pressure drop correlations for finned plate ceramic heat exchangers
(2015)
© 2015 Elsevier Ltd.The use of ceramic materials is a good option to build heat exchangers for high temperature applications when cost is a concern. This work presents heat transfer and pressure drop correlations for one ...

Symmetric nonlocal weighted density approximations from the exchange-correlation hole of the uniform electron gas
(American Chemical Society, 2012)
Nonlocal exchange-correlation energy functionals are constructed using the accurate model exchange-correlation hole for the uniform electron gas developed by Gori-Giorgi and Perdew. The exchange-correlation hole is constrained ...
Random sums of exchangeable variables and actuarial applications
(ELSEVIER SCIENCE BV, 2008)
In this paper we study the accumulated claim in some fixed time period, skipping the classical assumption of mutual independence between the variables involved. Two basic models are considered: Model I assumes that any ...
Non-newtonian heat transfer on a plate heat exchanger with generalized configurations
(Wiley-Blackwell, 2007-01-01)
For the configuration optimization of plate heat exchangers (PHEs), the mathematical models for heat transfer and pressure drop must be valid for a wide range of operational conditions of all configurations of the exchanger ...

Atomic spin-density polarization index and atomic spin-density information entropy distance
(2002)
It is shown that information theory concepts based on the Shanon entropy are useful to define indices yielding a quantitative measure of spin polarization. Numerical results for the ground state of all the atoms from He ...
