A Predictive Model on Pipeline CorrosionBy C. P. Ukpaka, Ekperi N. I.
Abstract: A comprehensive mathematical model is developed to predict corrosion rates in pipeline. The specimenused for this design is coupons (mild steel). Four containers with different solvents of 0.5 concentrationof nitric acids, 0.5 concentration of HCl, fresh water, and saltwater respectively were provided, andthe four paired coupons were placed inside the solvent for seven days. Each day, the coupons wereremoved, washed, dried, weighed, and placed back into the solvent. The result …

MATLAB Simulation Processes on Pneumatic Force-Balance TransmitterBy C. P. Ukpaka, Juliet Belema Gift Onyeson
Abstract: A pneumatic force balance transmitter in which an input force proportional to the fluid flow rate being measured is applied to a force bar pivoted about a transverse axis to produce a torque. A rebalance torque is applied to the bar by means of a negative feedback loop, in which a pneumatic detector functions to sense any change in bar position, the detector output being amplified to produce a pneumatic …

Predictive Model to Monitor the Effect of Angular Momentum of an Electron in an OrbitalBy C. P. Ukpaka, G. O. Chie-Amadi, P. Elechi
Abstract: Mathematical model was developed to examine the effect of angular momentum of an electron in an Orbital. The Lamor procession and vector of angular momentum function of the S,P orbitals revealed increase in the angular momentum with increase in orbital. The trend on spd orbital in terms of angular momentum shows the same behaviors as well as spdf orbital. The quantum angular momentum shows that the energy of the system …

Application of Schrödinger Wave Equation to Predict Wave Function on the Influence of DisplacementBy C. P. Ukpaka, I. C. Okara
Abstract: This research work contains a review of the Finite-Difference Time-Domain method as applied to the time-dependent Schrödinger wave equation, and the basic update equations are derived in their standard form. A simple absorbing boundary condition was formulated and shown to be effective with narrowband wave functions. The stability criterion was derived from a simple, self explaining perspective and found to give better efficiency than earlier attempts. Conclusively, the idea of …

Examination of the Amplitude Equation to the Characteristics of Harmonic Oscillators: The Concept of Schrodinger Wave EquationBy C. P. Ukpaka
Abstract: Although Heisenberg’s matrix mechanics was developed first, the Schrödinger equation was the first useful quantum wave equation. However, the Schrödinger equation is applicable only to non-relativistic cases. As opposed to classical physics, where the wave equation can be derived from first principles, in quantum physics the wave equation is obtained by a plausibility argument based on classical physics and the de Broglie hypotheses. Inserting the de Broglie relations. A frequently …

Prediction of Ionic Polarization of Na+ and Cl- Ions in a Lattice Upon the Influence of DisplacementBy C. P. Ukpaka
Abstract: This research demonstrates an interest because of the contribution to examine the importance on the characteristics of the certain behaviors of dielectric material, which do not give rise to an active current that leads to ionic polarization, and this attribute to the fact that when some of the atoms of the molecule have an excess positive or negative charge, an electric field will tend to shift positive ions relative to …
