Information Rheology: Information Cannot Test Truth
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 5
The statement about the property of some definite thing is not usually the only one. The difference between the stated property and the property of such a definite thing is one type of information rheology. Its origin is that the interaction of a definite thing with other things is incomplete. Based on the definition of customarily-called information and its mathematical expression, this...

Latent Heat Storage System- A Panacea to Address Energy Needs
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 5
The need for alternative sources of energy is of vital importance in the present time when the world’s non-renewable energy sources are rapidly getting depleted. The reason for this depletion is that humans are utilizing the energy at a much faster rate than is being produced. Additionally, in some cases, it is inevitable that the primary source of certain forms of energ...

A Review of Higher Order Statistics and Spectra in Communication Systems
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 4
There are many statistical tools to extract information from random signals. They predominantly use first and second order statistics. However, in the presence of nonlinearity in systems, many signals cannot be analyzed adequately by second order statistical methods. For this reason, higher order statistical methods have been developed. These methods are very useful in problems where non...

On the Invalidity of the Hawking-Penrose Singularity ‘Theorems’ and Acceleration of the Universe from Negative Cosmological Constant
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 4
Hawking and Penrose proposed “A new theorem on spacetime singularities … which largely incorporates and generalizes the previously know results†which they claimed “implies that space-time singularities are to be expected if either the universe is spatially closed or there is an ‘object’ undergoing r...

Magnetoresistance of InxGa1-xAs Thin Film Prepared by MBE
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 4
Magnetoresistance measurements were made on Thin Films of InxGa1-xAs from Electrical resistivity and Hall Effect measurements. Films used in this study were grown on single crystal GaAs substrate by Molecular Beam Epitaxial method. Measurements were made at room temperature and up to field strength of 5.5KG. Resistivity of GaAs and In0.14Ga0.86As at room temperature are 65.3 Ohm-cm and 7...
On Contributions of S. T. Yau in Mathematics and Physics Related to General Relativity
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 4
Due to inadequacy in pure mathematics among physicists, the non-existence of dynamic solutions for the Einstein equation was not recognized. Instead, his field equation was perpetuated. The positive energy theorem of Schoen and Yau also continues such an error. Although Yau may not have made errors in mathematics, their positive energy theorem produced not only just useless but also misl...
Higher Order DNS on an Airfoil Fx77-W500 Using Spectral/hp Method
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 4
The prediction of aerodynamic properties of thick airfoils is a tricky business for the blade manufactures. Computational fluid dynamics (CFD) offers a number of significant advantages to investigate the flow properties around airfoils, however, most turbulence models are working properly except having some problems in case of turbulent separation. The spectral/hp elements method offers ...

On the Nobel Prize in Physics, Controversies, and Influences
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 3
The Nobel Prizes were established by Alfred Bernhard Nobel for those who confer the "greatest benefit on mankind", and specifically in physics, chemistry, peace, physiology or medicine, and literature. In 1968 the Nobel Memorial Prize in Economic Sciences was established. However, the proceedings, nominations, awards, and exclusions have generated criticism and controversy. The controver...

LRS Bianchi Type – II Universe in f(R,T) Theory of Gravity
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 2
LRS Bianchi Type-II space – time is considered in the presence of a perfect fluid source in the framework of f(R,T) gravity proposed by Harko et al. [Phy.Rev-D 84, 024020(2011)]. An exact cosmological model with an appropriate choice of the function f(RT) is obtained using a special law of variation for Hubble’s parameter proposed by Bermann ( Nuovo Cime...

An Investigation on the Radiation Hazards Associated with the Use of Abakaliki Pyroclastic from Southeastern Nigeria as Construction Materials
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 2
This paper presents an investigation on the health risks that may be associated with pyroclastic rocks when used as construction materials. Radionuclides in the pyroclastic rocks from the Abakaliki and Ezillo areas (both in Ebonyi State, Southeastern Nigeria) were assessed. Data show that the uranium concentration in the pyroclastic rocks vary from 1 – 3 ppm (or 0.01 Ã...

FRW Viscous Fluid cosmological Model in f(R,T) Gravity
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 3
Friedmann -Robertson-Walker (FRW) space time is considered in f(R,T) gravity proposed by Harko et al. (Phys.Rev.D 84, 024020, 2011) when the source for energy momentum tensor is a bulk viscous fluid. A barotropic equation of state for the pressure and energy density is assumed to get a determinate solution of the field equations. Also the bulk viscous pressure is assumed to be proportion...
