Chaotic Oscillations of Nonideal Plane Pendulum Systems [PDF]

open access: yes, 2012
The atlas of maps of dynamic regimes of system ”pendulum–electric motor” is constructed. It is established that the deterministic chaos is a typical steady-state regime of the given system. Its class of Feigenbaum universality is defined.

Mortality can produce predictable dynamics in chaotic populations

open access: yes, 1997
Recent theoretical studies have pointed our that a relatively small degree of dispersion between chaotic subpopulations produces predictable, simple dynamics and severely reduces the frequency of the occurrence of chaos.

PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Control of chaotic finance system using artificial neural networks

open access: yes, 2015
In this paper, the control of a chaotic finance system is applied by using Artificial Neural Networks (ANNs). Economic systems become more complicated and have undesired nonlinear factors. It is difficult to control when a chaotic behaviour occurs.

Material‐Driven Neuronal Oscillators and Filters via Active Reactance in CC‐NDR and VC‐NDR Electro‐Thermal Memristors

open access: yesAdvanced Physics Research, EarlyView.
Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Controlling chaos in a chaotic neural network

open access: yes, 2003
The chaotic neural network constructed with chaotic neuron shows the associative memory function, but its memory searching process cannot be stabilized in a stored state because of the chaotic motion of the network.

Guiding and Manipulating Light Fields in Microstructured Liquid Crystals

open access: yesAdvanced Physics Research, EarlyView.
This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Secure communication based on indirect coupled synchronization

open access: yes, 2012
In this paper, a secure communication system composed of four chaotic oscillators is proposed. Two of these oscillators are unidirectionally coupled and employed as transmitter and receiver.
