S-4 solution of the transport equation for eigenvalues using Legendre polynomials
(EDP SCIENCES., 2017)Numerical solution of the transport equation for monoenergetic neutrons scattered isotropically through the medium of a finite homogeneous slab is studied for the determination of the eigenvalues. After obtaining the ... -
S4 solution of the transport equation for eigenvalues: isotropic, forward and backward scattering in a slab
(SÜLEYMAN DEMİREL ÜNİV., 2017)The neutron transport equation is solved numerically for monoenergetic neutrons in a finite homogeneous slab with backward and forward scattering for the eigenvalue spectrum. The forward-backward-isotropic (FBI) scattering ... -
Semi-Empirical Formula with New Coefficients of the (alpha,n) Reaction Cross-Section
(POLISH ACAD SCIENCES INST PHYSICS, 2015)A new modified semi-empirical formula including non-elastic scattering and Coulomb effects for the (alpha,n) reaction cross-section was obtained. The available experimental data were used to get the (alpha,n) reaction ... -
Semigroup presentation for congruences on groups
(KOREAN MATHEMATICAL SOC, 2013)We consider a congruence rho on a group G as a subsemigroup of the direct product G x G. It is well known that a relation rho on G is a congruence if and only if there exists a normal subgroup N of G such that rho = {(s, ... -
Set similarity modulates object tracking in dynamic environments
(SPRINGER, 2018)Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers' abilities to track a ball target passed between 20 colored circle ... -
Short- and long-term forms of neural adaptation: An ERP investigation of dynamic motion aftereffects
(ELSEVIER MASSON,, 2020)Adaptation is essential to interact with a dynamic and changing environment, and can be observed on different timescales. Previous studies on a motion paradigm called dynamic motion aftereffect (dMAE) showed that neural ... -
