Advanced monitoring, fault detection, automatic control and optimisation of the beer fermentation process require on-line prediction and off-line simulation of key variables. Three dynamic models for the beer fermentation process are proposed and validated in laboratory scale: a model based on...

Rationalized Haar functions are developed to approximate the solution of the differential equations. Properties of rationalized Haar functions are first presented, the operational matrix of integration together with product operational matrix are utilized to reduce the computation of...

Nonlinear shock waves which appear in a nonlinear Toda lattice with internal dissipation have been studied. The tanh method is used as a perturbation approach together with the assumption of long wavelengths. Moreover, asymptotical behaviour is used to determine the velocity. Burgers-like wave...

We study the singularly perturbed (sixth-order) Boussinesq equation recently introduced by Daripa and Hua [Appl. Math. Comput. 101 (1999) 159]. This equation describes the bi-directional propagation of small amplitude and long capillary-gravity waves on the surface of shallow water for bond...

Different problems addressed to the efficiency of the water use and allocation are of great importance in numerous regions including Middle East. Water scarcity is the foremost problem for which solutions are urgently needed. Water prices can be considered as an instrument for satisfactory water...

The use of tomato vibration analysis after impact excitation as a non-destructive physical quality measurement was investigated. For this purpose, an off-line test set-up was constructed that automatically impacts the tomato and captures the response. It is shown that the resonant frequency of...

The problem of identifiability of parameters has hardly ever been considered in the case of uncontrolled systems whereas many efficient methods have been developed for controlled systems. In this paper, we are pointing out two procedures to get global identifiability results of uncontrolled...

Currently, in the context of quasi-Monte Carlo applications the most effective low-discrepancy sequences are digital (t, s)-sequences.

Modelling and simulation have been assigned crucial roles in the design, development, analysis and evaluation of computer architectures. The design of parallel architectures in particular is a complex and difficult endeavour that makes modelling and simulation essential tools. In this case, high...
