Optimal fluctuations and the control of chaos. [PDF]

open access: yes, 2002
The energy-optimal migration of a chaotic oscillator from one attractor to another coexisting attractor is investigated via an analogy between the Hamiltonian theory of fluctuations and Hamiltonian formulation of the control problem.

Twin rotor system modeling, de-coupling and optimal control [PDF]

open access: yes, 2011
This paper proposes a new method to model, de-couple and implement a optimal control for a twin rotor system. We first model and decouple this twin rotor system into two independent single input single output (SISO) systems, and consider the coupling ...

Incident duration modelling and system optimal traffic re-routing [PDF]

open access: yes, 2017
Traffic incidents are among the most significant contributory factors to congestion, particularly in metropolitan areas. In this dissertation, we have developed state-of-the-art statistical models to provide in-depth insights into how various incident ...

Symmetries of Ricci flows

open access: yesAdvances in Nonlinear Analysis, 2023
In the present work, we find the Lie point symmetries of the Ricci flow on an n-dimensional manifold, and we introduce a method in order to reutilize these symmetries to obtain the Lie point symmetries of particular metrics.

An optimal system of group-invariant solutions and conserved quantities of a nonlinear fifth-order integrable equation

open access: yesOpen Physics, 2020
In this work, we perform Lie group analysis on a fifth-order integrable nonlinear partial differential equation, which was recently introduced in the literature and contains two dispersive terms.

The ascending arousal system promotes optimal performance through mesoscale network integration in a visuospatial attentional task

open access: yesNetwork Neuroscience, 2021
Previous research has shown that the autonomic nervous system provides essential constraints over ongoing cognitive function. However, there is currently a relative lack of direct empirical evidence for how this interaction manifests in the brain at the ...

Hyperspectral Anomaly Detection via Discriminative Feature Learning with Multiple-Dictionary Sparse Representation

open access: yesRemote Sensing, 2018
Most hyperspectral anomaly detection methods directly utilize all the original spectra to recognize anomalies. However, the inherent characteristics of high spectral dimension and complex spectral correlation commonly make their detection performance ...

Integrated Optimal Design of a Passive Wind Turbine System: An Experimental Validation [PDF]

open access: yes, 2010
This work presents design and experimentation of a full passive wind turbine system without active electronic part(power and control). The efficiency of such device can be obtained only if the system design parameters are mutually adapted through an ...
