Introduction
I actively research on almost every subject where math is used to analyze it. I am Jack of all trades, master of all (my bragging right !). Moreover, I am an honorary PHM professor.

Full-text available
Modeling dynamics of mechanical systems is of high importance in engineering and science. Such dynamic models are conventionally inevitably constructed through long history of success, with recourse to Newtonian dynamics and its alternative formulation, called Lagranian dynamics. However, Newtonian dynamics, although is simple and somehow general,...

An applied nonlinear control theory, namely the hyper-exponential control theory (HECT), is developed. The development of the theory, owes itself to the control-Lyapunov function methodology concepts. It facilitates robust global output feedback stabilization of general class of nonlinear systems, through universal time-varying feedback law. HECT i...

Full-text available
Laplace-transform theory is conventionally used as powerful tool for filtering purpose and is theoretically well-established research arena. Through novel standpoint, aim of current study, is to develop a formula for Laplace-transform of multiplicative inverse of a function. Using the convolution formula, along with rigorous mathematical analysis a...
Conference Paper
Full-text available
A theoretical study regarding experimental development of a nonlinear control loader system for a vertical flight motion simulator is presented. Coupled stick-aircraft dynamics during an active 3-DOF nonlinear maneuver in the vertical plane is simulated in the MATLAB SIMULINKTM software environment that facilitates a near-exact simulation of contro...

In this paper an alternative for Newton's second law of motion (Newtonian dynamics) is presented; named critically modified Newtonian dynamics (CMOND). Newton's second law of motion is proved to be a special case of CMOND. CMOND does not totally refute Newton's second law of motion, though is observed to be much more general than that and is a diff...
Thesis
Full-text available
The main focus of this paper is on efficiency analysis of two kinds of approximating functions (characteristic orthogonal polynomials and characteristic beam functions) that have been applied in the Rayleigh-Ritz method to determine the non-dimensional buckling and frequency parameters of an angle ply symmetric laminated composite plate with fully...

Question
The Laplace-transform is defined by the integral:
F(s)=L{f(t)}=integrate(exp(-st)*f(t)*dt, t=0...∞).
It is interesting to spot that, the following integral has the same numerical value in time-domain as:
F(t)=L{f(t)}=integrate(exp(-st)*f(s)*ds, s=0...∞).
We may conclude that:
F(s)=F(t).
A new type of symmetry? What are the benefits?
Please, let me know your viewpoints.
Thank you.

While some research literature propose drone-based surveillance for fault detection in solar photovoltaic cell parks, I suggest an Earth-fixed station equipped with some electronic circuitry boards and a computer connected to the solar-panel arrays, which could detect the faults by sensing the minute variations in voltage across the network, for online monitoring and fault-detection purpose, would be probably a better alternative than the entangling aerial drone surveillance proposed by some researchers.
