2 About Some Results of the Determination of Alcohol in Moroccan Gasoline-Alcohol Mixtures
Authors: Mahacine Amrani
Abstract:
A simple and rapid method for the determination of alcohol in gasoline-alcohol mixtures using density measurements is described. The method can determine a minimum of 1% of alcohol by volume. The precision of the method is ± 3%.The method is more useful for field test in the quality assessment of alcohol blended fuels.Keywords: gasoline-alcohol, mixture, alcohol determination, density, measurement, Morocco

Authors: Mahacine Amrani
Abstract:
This paper aims at reviewing some Moroccan industrial applications of wavelet especially in the dynamic identification of a process model using Haar wavelet mother response. Two recent Moroccan study cases are described using dynamic data originated by a distillation column and an industrial polyethylene process plant. The purpose of the wavelet scheme is to build on-line dynamic models. In both case studies, a comparison is carried out between the Haar wavelet mother response model and a linear difference equation model. Finally it concludes, on the base of the comparison of the process performances and the best responses, which may be useful to create an estimated on-line internal model control and its application towards model-predictive controllers (MPC). All calculations were implemented using AutoSignal Software.Keywords: process performance, model, wavelets, Haar, Moroccan
