Mobile game development for children with down syndrome
(International Association of Online Engineering, 2021)Children with diagnosis of down syndrome has different kinds of personalities, mental states, and talents similar to other children. The key point is that every child needs proper support at the right time. There are ... -
A new Einstein-nonlinear electrodynamics solution in 2+1-dimensions
(Springerlink, 2013)We introduce a class of solutions in 2 + 1−dimensional Einstein-Power-Maxwell theory for circularly symmetric electric field. The electromagnetic field is considered with an angular component given by Fµν = E0δ t µδ θ ν ... -
New singular and nonsingular colliding wave solutions in Einstein-Maxwell-Scalar theory.
(Springerlink, 2003)A technique is given to generate coupled scalar field solutions in colliding Einstein-Maxwell (EM) waves. By employing the Bell - Szekeres solution as seed and depending on the chosen scalar field, it is possible to ... -
Null singularities in colliding waves
(Cornell University, 2001)Colliding Einstein - Maxwell - Scalar fields need not necessarily doomed to become in a spacelike singularity. Examples are given in which null singularities emerge as intermediate stages between a spacelike singularity ... -
Null singularity formation by scalar fields in colliding waves and black holes
(Cornell University, 2002)It was believed that when gravitational, electromagnetic and scalar waves interact, a spacelike curvature singularity or Cauchy horizon develops because of mutual focusing. We show with an exact solution that the collision ... -
Quantum probe of Hoˇrava-lifshitz gravity
(Cornell University, 2018)Particle probe analysis of the Kehagias - Sfetsos black hole spacetime of Hoˇrava-Lifshitz gravity is extended to wave probe analysis within the framework of quantum mechanics. The timelike naked singularity that develops ... -
Quantum probe of time-like naked singularities for electrically and magnetically charged black holes in a model of nonlinear electrodynamics
(World Scientific Connecting Great Minds, 2020)The time-like naked singularities of the electrically and magnetically charged black hole solutions obtained in a model of nonlinear electrodynamics proposed by Kruglov is investigated within the framework of quantum ... -
Quantum probes of timelike naked singularities in the weak eld regime of f(R) global monopole spacetime
(Springerlink, 2014)The formation of a naked singularity in f(R) global monopole spacetime is considered in view of quantum mechanics. Quantum test elds obeying the Klein-Gordon, Dirac and Maxwell equations are used to probe the classical ... -
Quantum singularities in (2+1) dimensional matter coupled black hole spacetimes
(APS Physics, 2012)Quantum singularities considered in the 3 D BTZ spacetime by Pitelli and Letelier (Phys. Rev. D77: 124030, 2008) is extended to charged BTZ and 3D Einstein-Maxwell-dilaton gravity spacetimes. The occurence of naked ... -
Quantum singularities in a model of f(R) gravity
(Springerlink, 2012)The formation of a naked singularity in a model of f(R) gravity having as source a linear elec- tromagnetic field is considered in view of quantum mechanics. Quantum test fields obeying the Klein−Gordon, Dirac and Maxwell ... -
Reductions of topologically massive gravity II. First order realizations of second order Lagrangians
(American Institute of Physics, 2020)Second order degenerate Clement and Sarolu-Tekin Lagrangians are casted into forms of various first order Lagrangians. The structures of the iterated tangent bundle and acceleration bundle are presented as a suitable ... -
Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves
(APS Physics, 2006)We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave. ... -
Restricted class of colliding Einstein-Yang-Mills plane waves
(WorldScientific, 2009)By gauging an Abelian electromagnetic (em) solution through a non-Abelian transformation and in accordance with a theorem proved long time ago, we construct a simple class of colliding Einstein-Yang-Mills (EYM) plane ... -
Rindler modified schwarzschild geodesics
(Springerlink, 2013)The mysterious attractive constant radial force acted in the past on Pioneer spacecrafts - the so-called Pioneer anomaly - is considered within the context of Rindler acceleration. As an idea this is tempting since it ... -
Search for gravitational waves through the electromagnetic faraday rotation
(APS Physics, 2007)A method is given which renders indirect detection of strong gravitational waves possible. This is based on the reflection (collision) of a linearly polarized electromagnetic shock wave from (with) a cross polarized ... -
Wavy way to the Kerr metric and the quantum nature of its ring singularity
(Cornell University, 2016)From inherent non-linearity two gravitational waves, unless they are unidirectional, fail to satisfy a superposition law. They collide to develop a new spacetime carrying the imprints of the incoming waves. Same behaviour ...
