Mathematical properties of the rotational diffusion equation [PDF]

Journal of Physics A: Mathematical and General, 2001
An iterative scheme for the approximative solution of the Galerkin system of the linear rotational diffusion equation for the chromophore distribution in nonlinear optical polymers is formulated. Uniformly valid asymptotic steady-state solutions are obtained in terms of power series expansions in the normalized dc field and the convergence properties ...

Longitudinal Analysis of Associations between 3-D Mental Rotation and Mathematics Reasoning Skills during Middle School: Across and within Genders

Journal of Cognition and Development, 2019
The development of math reasoning and 3-d mental rotation skills are intertwined. However, it is currently not understood how these cognitive processes develop and interact longitudinally at the within-person level – either within or across genders.

“Bold Problem Solving”: A New Construct for Understanding Gender Differences in Mathematics

, 2021
Despite progress toward gender equity, troubling disparities in mathematical problem-solving performance and related outcomes persist. To investigate why, we build on recurrent findings in previous studies to introduce a new construct, “bold problem ...

Mathematical Description of the Rotating Error Motion

Key Engineering Materials, 2006
According to the definitions of the CIRP Unification Document, The locus equations of the rotating center and the average rotating center are deduced, and then, the parameter equations of the rotating axis and the average rotating axis are obtained. All of above verify the definition of the rotating axis of the CIRP Unification Document in theory, and ...

Spatial reasoning, mathematics, and gender: Do spatial constructs differ in their contribution to performance?

British Journal of Educational Psychology, 2020
BACKGROUND The role of gender in both spatial and mathematics performance has been extensively studied separately, with a male advantage often found in spatial tasks and mathematics from adolescence.
