Propagation Methods for Quantum Molecular Dynamics
TL;DR: In this paper, a recursive application of the elementary mapping step, termed the propagator, is presented, in a time-dependent description of quantum molecular dynamics, where a propagator U(z) maps the waw-function at time t, p(t) to the wave function at time n + n, 0(t+n) = n 0(n)0(t).

Current state of modeling the photochemistry of Titan's mutually dependent atmosphere and ionosphere
E. H. Wilson,Sushil K. Atreya +1 more
TL;DR: In this article, a two-stream discrete ordinates method was employed to characterize the transfer of solar radiation, and the effects of electron-impact, cosmic-ray deposition, and aerosol opacities from fractal and Mie particles.
HZETRN: Description of a Free-Space Ion and Nucleon Transport and Shielding Computer Program
W Wilson John,F Badavi Francis,A Cucinotta Francis,L Shinn Judy,D Badhwar Gautam,R Silberberg,C. H. Tsao,W Townsend Lawrence,K Tripathi Ram +8 more
TL;DR: The high charge and energy (HZE) transport computer program HZETRN as mentioned in this paper was developed to address the problems of free-space radiation transport and shielding and was intended specifically for the design engineer who was interested in obtaining fast and accurate dosimetric information for the development and construction of space modules and devices.

Multi-objective fuzzy regression: a general framework
TL;DR: A multi-objective fuzzy regression (MOFR) tool is developed to overcome the shortcomings of existing fuzzy regression approaches while keeping their good characteristics, and to study systems with uncertain elements, using the example of rainfall-runoff processes to illustrate the approach.
