An Approach for the Generation of an Nth-Order Chaotic System with Hyperbolic Sine

open access: yesEntropy, 2018
Chaotic systems with hyperbolic sine nonlinearity have attracted the attention of researchers in the last two years. This paper introduces a new approach for generating a class of simple chaotic systems with hyperbolic sine.

Stochastic noise and synchronisation during Dictyostelium aggregation make cAMP oscillations robust [PDF]

open access: yes, 2007
Stable and robust oscillations in the concentration of adenosine 3′, 5′-cyclic monophosphate (cAMP) are observed during the aggregation phase of starvation-induced development in Dictyostelium discoideum.

Analytical solutions using special trans functions theory for current–voltage expressions of perovskite solar cells and their approximate equivalent circuits

open access: yesAin Shams Engineering Journal, 2023
Perovskite solar cells (PSC) have been recognized as devices with a constant increase in power conversion efficiency, confirming this promising technology’s upward trend. This paper deals with the mathematical modeling of current voltage and inverse voltage-current relationships of PSCs, in which standard equivalent circuits, as well as approximate ...

Modelling delay and noise in arbitrarily coupled RC trees. [PDF]

open access: yes, 2005
Closed-form equations for second-order transfer functions of general arbitrarily coupled resistance-capacitance (RC) trees with multiple drivers are reported. The models allow precise delay and noise calculations for systems of coupled interconnects with

Winding Design and Analysis for a Disc-Type Permanent-Magnet Synchronous Motor with a PCB Stator

open access: yesEnergies, 2018
The stator structure of a disc-type permanent-magnet synchronous motor is a printed circuit board (PCB). The design of stator windings has a direct influence on motor performance and the utilization rate of the stator.
