In recent years, neural networks have attracted much attention for their potential to address a number of difficult problems in modelling and controlling nonlinear dynamic systems, especially in (bio) chemical engineering. The objective of this paper

Simultaneous perturbation stochastic approximation (SPSA) is a gradient-based optimization method which has become popular since the 1990s. In contrast with standard numerical procedures, this method requires only a few cost function evaluations to o

This paper is concerned with a pilot-scale fixed-bed biofilter used for nitrogen removal from municipal wastewater. Process modelling yields a set of mass balance partial differential equations describing the evolution of the component concentrations

Learning, i.e. estimation of weights and biases in neural networks, involves the minimization of an output error criterion, a problem which is usually solved using back-propagation algorithms. This paper aims to assess the potential of simultaneous p

The sparsity and low quality of measurement data in biochemical applications often make the development of black-box neural network models particularly delicate. Hence, it is appealing to resort to a hybrid physical-neural network approach, which com

Three-dimensional flow through an anatomically representative model of the human larynx has been numerically simulated. This model includes the vestibular folds, the vocal cords and the glottic and subglottic areas. Pseudo-time-varying glottic apertu

This paper focuses on modelling of an industrial cement grinding circuit using physical arguments and experimental data. The resulting ‘grey-box’ model, which consists of a mixed set of algebraic and partial differential equations, can be used to

A multipath model of the mechanical behaviour of healthy lungs subject to a plethysmographic test (close to quiet breathing conditions) has been developed, which includes the main physiological nonlinearities. This model is built on a symmetric branc

The thermal behavior of the constant volume body plethysmograph under the thermal effect of the patient and the thermostatic bag is modeled by two relations: the first is between the temperature in the box and the heat flux generated by the patient a

Simultaneous perturbation stochastic approximation (SPSA) is a class of optimization algorithms which compute an approximation of the gradient and/or the Hessian of the objective function by varying all the elements of the parameter vector simultaneo
