Cramming multiple pairs of shoes into a vacation suitcase, twisting and flipping them into different arrangements to fit every pair needed, is a familiar optimization problem faced by harried traveler...
Light-likeness of Bordlines of Extremal Surfaces of Mixed Type in Physical Space-times
Light-likeness Bordlines Extremal Surfaces Mixed Type Physical Space-times
2018/4/19
In this paper, we prove the light-likeness of bordlines of smooth extremal surfaces of mixed type in general physical space-times, and for the case of the (1+2)-dimensional Minkowski space R1+2, we im...
Dynamical light control in longitudinally modulated segmented waveguide arrays
ongitudinally modulated segmented waveguide arrays Dynamical light
2011/7/7
We address light propagation in segmented waveguide arrays where the refractive index is longitudinally modulated with an out-of-phase modulation in adjacent waveguides, so that the coupling strength ...
Tracing light propagation to the intrinsic accuracy of space-time geometry
relativity gravitation space-time geometry weak field approximations light propagation
2011/3/4
Advancement in astronomical observations and technical instrumentation requires coding light
propagation at high level of precision; this could open a new detection window of many subtle relativistic...
Optimization of a photobioreactor biomass production using natural light
Optimal control Biological systems Modeling
2010/12/3
We address the question of optimization of the biomass long term productivity
in the framework of microalgal biomass production in photobioreactors under the influence
of day/night cycles.
The gravity of light
gravity light
2010/12/16
The light can be source of gravitational waves belonging to a large class of exact solutions of Ein-stein eld equations which are invariant for a non-Abelian 2-dimensional Lie algebra of Killing eld...
Filamentation processes and dynamical excitation of light condensates in optical media with competing nonlinearities
dynamical excitation light condensates optical media competing nonlinearities
2010/4/2
We analyze both theoretically and by means of numerical simulations the phenomena of filamentation and dynamical formation of self-guided nonlinear waves in media featuring competing cubic and quintic...
It is well-known that a torsion-free linear connection on a light-like manifold (M,g) compatible with the degenerate metric g exists if and only if Rad(TM) is a Killing distribution. In case of existe...
