Electro-gravitational Technology via Chronon Field

Eytan H. Suchard · Physical Science International Journal · 2014

Aim: To develop a model of matter that will account for electro-gravity. Matter is characterized by force fields and in non-inertial and non-geodesic motion as a result of interactions. The measurement of how non geodesic a test particle is can be done by non-geodesic acceleratio...

Multidimensional Treatment of the Expanding Universe

I. A. Urusovskii · Physical Science International Journal · 2014

The simplest six-dimensional treatment of the expanding Universe in the form a three-dimensional sphere appeared as a result of the intersection of three simplest geometrical objects of finite sizes in the six-dimensional Euclidean space – of three uniformly expanding five-dimens...

D-optimal Exact Design: Weighted Variance Approach and a Continuous Search Technique

Otaru O. Paul & Enegesele Dennis · Physical Science International Journal · 2014

In design of experiment, researchers have formulated various methods for obtaining D-optimal design. The aim of this study therefore is to obtain an N-point exact D-optimal design for a feasibleregion defined on a polynomial model. The weighted variance approach and a continuous...

Analytical Investigation of Electrons Capture Time Effect on the Threshold Current Density Reduction in QD Spin-Lasers

S. N. Hosseinimotlagh, H. Ghavidelfard & A. Shakeri · Physical Science International Journal · 2014

In this paper, we solve numerically the rate equations governing the  semiconductor spin with un-polarized and polarized laser field based on quantum dot active region in which Schottky tunnel barrier treats as the spin injector. We demonstrate simultaneously the effects of elect...

Effect of Annealing Process on Porous Aluminium Filled with Graphite

Amel Lafi Al-Otaibi, Muneera Abdullah Al-messiere & Taher Ghrib · Physical Science International Journal · 2014

Thermal properties of porous thin films formed by anodization of thin aluminum films in sulfuric acid. The obtained pores at the surface are filled by sprayed graphite which the role is to improving its optical and thermal absorption giving a structure of an assembly of three dif...

Entropy and Temperature from Entangled Space and Time

Young S. Kim & Marilyn E. Noz · Physical Science International Journal · 2014

Two coupled oscillators provide a mathematical instrument for solving many problems in modern physics, including squeezed states of light and Lorentz transformations of quantum bound states. The concept of entanglement can also be studied within this mathematical framework. For t...
