CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

AIChE Journal, EarlyView.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

TOOLS FOR DETECTING CHAOS

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2005
I n this study, useful tools for detecting chaos are explained. To observe the state variabtes (time series}, the phase portrait, the Poincare map, the power spectrum, the Lyapunov exponents and bifurcation diagram are used to detect chaos in dynamical ...

On Fractional Discrete-Time Power Systems: Chaos, Complexity and Control

Mathematics
In this paper, based on the Caputo-like delta fractional difference operator, we will present a fractional discrete model of a 4D Power System. We present an extension of the popular integer-order single-machine infinite-bus formulation to two fractional

A Novel Control Method for Integer Orders Chaos Systems via Fractional-Order Derivative

Discrete Dynamics in Nature and Society, 2011
A fractional-order control method is obtained to stabilize the point in chaos attractor of integer orders chaos systems. The control law has simple structure and is designed easily.

Stability and Period-Doubling Bifurcation of Fractional-Order Commensal Symbiosis Model with Allee Effect

Fractal and Fractional
Differential equations with fractional order play an important role in modeling some natural phenomena. This paper investigates the dynamics of the fractional-order commensal symbiosis model with the Allee effect.

Nonlinear dynamics and chaos control of a discrete Rosenzweig-MacArthur prey-predator model

Journal of Innovative Applied Mathematics and Computational Sciences
This paper investigates the nonlinear dynamics and chaos control of a discrete Rosenzweig-MacArthur predator-prey model. We first conduct a thorough dynamical analysis, identifying the system's equilibrium points and examining their stability conditions.

Digital Communication Systems Based on Three-Dimensional Chaotic Attractors

IEEE Access, 2019
In this paper, we propose a methodology to design chaos-based communication systems, which exploits the topological structure of 3-D chaotic attractors. The first step consists in defining a proper partition of a Poincaré section of the attractor
