A circumzenithal arc to study optics concepts with geometrical optics
(Institute of Physics Publishing, 2017)
This paper describes the formation of a circumzenithal arc for the purpose of teaching light and optics. A circumzenithal arc, an optic formation rarely witnessed by people, is formed in this study using a water-filled ...
Shell-ferromagnetic precipitation in martensitic off-stoichiometric Ni-Mn-In Heusler alloys produced by temper-annealing under magnetic field
(Elsevier Ltd, 2017)
The variety of the multifunctional properties of martensitic Ni-Mn based Heusler alloys are related to the presence of a magnetostructural transition. We report here on a new functionality based on a newly observed property. ...
Bernstein Operational Matrix with Error Analysis for Solving High Order Delay Differential Equations
(Springer, 2017)
In this paper, we propose a numerical method based on Bernstein polynomials and their operational matrices for solving both linear and non-linear delay differential equations (DDEs). The Bernstein operational matrices for ...
