A CONCEPTUAL FRAMEWORK FOR SUSTAINABLE eHEALTH IMPLEMENTATION IN RESOURCE-CONSTRAINED SETTINGS

open access: yesSouth African Journal of Industrial Engineering, 2018
There is evidence that several eHealth pilot projects in developing countries could not progress to full-scale implementation — sometimes referred to as the ‘pilotitis’ of the eHealth system.

Governing equation discovery based on causal graph for nonlinear dynamic systems

open access: yesMachine Learning: Science and Technology, 2023
The governing equations of nonlinear dynamic systems is of great significance for understanding the internal physical characteristics. In order to learn the governing equations of nonlinear systems from noisy observed data, we propose a novel method ...

Pricing options in illiquid markets: optimal systems, symmetry reductions and exact solutions

open access: yes, 2010
We study a class of nonlinear pricing models which involves the feedback effect from the dynamic hedging strategies on the price of asset introduced by Sircar and Papanicolaou. We are first to study the case of a nonlinear demand function involved in the

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Application of dynamic accuracy evaluation for press systems based on orthogonal design method

open access: yesMethodsX
The variation of dynamic accuracy for press systems is the nonlinear phenomenon that results from the consideration of contact and impact on the deformation of transmission mechanism, usually revolute joint and translation joint.

Fault Detection in Nonlinear Systems Via Linear Methods

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
The problem of robust linear and nonlinear diagnostic observer design is considered. A method is suggested to construct the observers that are disturbance decoupled or have minimal sensitivity to the disturbances.

An Alternating Frequency/Time Domain Method for Calculating the Steady-State Response of Nonlinear Dynamic Systems

open access: yes, 1989
A method is proposed for analyzing the steady-state response of nonlinear dynamic systems. The method iterates to obtain the discrete Fourier transform of the system response, returning to the time domain at each iteration to take advantage of the ease ...
