Stability Analysis of a Motor-Gear-Alternator (MGA) System Using Bode Plot Technique

Wesley Koech · Journal of Advances in Mathematics and Computer Science · 2017

Koech and the associates designed a Motor-Gear-Alternator (MGA) model and identified the effective parameters of that model. Nonetheless, the stability of the model to determine its applicability is still missing. In this paper, the author attempted to design a stable for Motor-G...

Estimated Numerical Results and Simulation of the Plant Disease Model Incorporating Wind Strength and Insect Vector at Equilibrium

A. L. M. Murwayi, T. Onyango & B. Owour · Journal of Advances in Mathematics and Computer Science · 2017

Numerical simulations facilitate in the study of the behaviour of systems whose mathematical models are too complex to obtain analytical solutions. In this paper, we used assumed values of the model parameters and variable to simulate a non-linear deterministic model for plant ve...

The “Vertical” Generalization of the Binary Goldbach’s Conjecture as Applied on “Iterative” Primes with (Recursive) Prime Indexes (i-primeths)

Andrei-Lucian Drăgoi · Journal of Advances in Mathematics and Computer Science · 2017

This article proposes a synthesized classification of some Goldbach-like conjectures, including those which are “stronger” than the Binary Goldbach’s Conjecture (BGC) and launches a new generalization of BGC briefly called “the Vertical Binary Goldbach’s Conjecture” (VBGC), which...
