On the Practical Assessment of Signal Strength of GSM Network Service Providers
Published In: GJSFR Part: A: Physics & Space Science Volume: 14 Issue: 1
This paper assessed the signal strength of GSM network service providers in Kwara State Polytechnic permanent site and Ara village. The latitude, longitude and elevation of the two reference locations where the study would be carry out were picked with Global Positioning System. The first location was at the gate of Kwara State Polytechnic permanent site at latitude 080 321 37.6 11 and l...

Traveling Wave Solutions of The (1+1)-Dimensional Compound KdVB equation by Exp -Expansion Method
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 8
In this article, we apply the ex−p ( Φ(η))-expansion method for seeking the exact solutions of NLEEs via the (1+1)-Dimensional Compound KdvB equation. Plentiful traveling wave solutions with arbitrary parameters are successfully obtained by this method and the wave solutions are expressed in terms of the hyperbolic, trigonometric, and rational functions. The...

Measurement of Liquid Volume in Stomach using 6-Elctorde FIM for Saline Water Intake at Periodic Intervals
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 7
Focused Impedance Measurement (FIM) is a relatively new technique developed in the Biomedical Physics Laboratory of Dhaka University which allows improved localization of a zone without much increase in complexity of the measuring instrumentation when the electrodes are applied on the skin surface with the organs inside contributing the measurement of impedance since the body is a volume...

Klein-Gordon Equation for a Particle in Brane Model
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 8
Brane model of universe is considered for a free particle. Conservation laws on the brane are obtained using the symme-try properties of the brane. Equation of motion is derived for a particle using variation principle from these conservation laws. This equation includes terms accounting the variation of brane radius. Its solution is obtained at some approx-imations. Dispersion relation ...

Effect of Power Law Temperature Variation on a Vertical Conical Annular Porous Medium
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 7
In this chapter, we concentrate on the study of heat transfer by natural convection in a saturated porous medium with a power law temperature variation on a vertical conical annular porous mediumâ€Â. In this study Finite Element Method (FEM) has been used to solve the governing partial differential equations. There have been considerable interest in studying natural or buoyan...

Errors of the Wheeler School, the Distortions to General Relativity and the Damage to Education in MIT Open Courses in Physics
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 7
General relativity is difficult to understand, and recently it is discovered as not yet self-consistent. Einstein’s theory of measurement is known as incompatible with the rest of physics, and thus misinterpretations were created. Among them, the dominant misinterpretations of the Wheeler School are due to inadequacy in mathematics and physics. In particular, their disto...
Evaluation of Condition Symptoms in Diagnosing Complex Objects
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 7
A method is proposed for selecting the most informative diagnostic symptoms in lifetime consumption monitoring of complex objects. Typically in such cases many symptoms are available and their suitability cannot be evaluated even with a detailed knowledge of object layout and operation. The proposed procedure involves two stages. Preliminary symptom selection is based on the Singular Val...

Rotating Light House Effect
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 6
We clarify as to how a precession period appears in the analysis of periodic phenomenon in Astrophysics. The observed redshift that is related to this phenomenon is shown to be 2a/V = 2 / T, where ‘a’ is the relative acceleration between the emitter and receiver and ‘V’ the relative transverse velocity. We find that the Hubble...

Determination and Optimization of Bulk Total Energy for Gallium-Arsenide (Gaas) Atom using FHI98MD Input Variables
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 6
The Optimization of bulk total energy Calculations have been performed using the Local Density approximation for the exchange-correlation functional of Perdew Wang, within density-functional theory (DFT) for Gallium-arsenide (GaAs) atom. The optimized values obtained were used to calculate the bulk total energy of Gallium-arsenide. These calculations were performed using the Density Func...

Dehydration Characteristics and Mathematical Modeling of Thyme Leaves using the Microwave Process
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 8
Thyme leaves (Thymus vulgaris) with 50 g weight and 83.7% humidity on wet basis were dried in a laboratory scale microwave dryer using six different microwave power levels ranging between 200 to 700 W. The effect of drying power microwave on the coefficients of the best moisture ratio model was determined by non-linear regression method. Results from the mathematical modeling showed that...

Some Observable Effects of Heat Flow in Response to Thermal Potentials at the Boundary
Published In: GJSFR Part: A: Physics & Space Science Volume: 13 Issue: 6
When heat flow is subject to temperature dependent thermal potential at the boundary, the associated local temperature field responds significantly, while the neighboring field is marginally influenced. This response results into effects quite intriguing. This paper examines these effects over a pure metallic plate. By considering both linear and non-linear thermal potentials induced at ...
