Public ISBD Titre : Failure identification methods for detecting leaks in pipelines and sensor faults Type de document : texte imprimé Auteurs : Benkherouf, Abdelkrim, Auteur ; A. Y. Allidina, Directeur de thèse Editeur : Manchester : [s.n.] Année de publication : 1985 Importance : 152 f. Présentation : ill. Format : 30 cm. Note générale : Phd Thesis : Mechanical engineering : Victoria University of Manchester : 1985 Bibliogr. f. 153 - 156 . - Annexe f. 157 - 168 Langues : Anglais (eng) Mots-clés : Pumps Filters Pipes Tubing Valves Pumping machinery Pipe Manufacturing processes Automatic control Index. décimale : D006385 Résumé : This thesis is concerned with the problem of detection and localisation of leaks in gas pipelines, and with the problem of sensor fault identification in large scale systems. Three different leak detection schemes are described in the first part of the thesis. The first method is based on the application of a model adjustment procedure to the Distributed Parameter (DP) system governing the gas flow process. In the other two methods, the estimation and localisation of the leak is achieved by using a Kalman filter for the DP system. Simulated observations are used to assess and compare the various methods. The second part of the thesis proposes a new approach for identifying sensor faults in large scale systems, using over-lapping decomposition and decentralised state estimation. A system with three sensors is used to illustrate the approach. Failure identification methods for detecting leaks in pipelines and sensor faults [texte imprimé] / Benkherouf, Abdelkrim, Auteur ; A.

Sequencing of the packing activity in large detergent plant / K. Belarbi (1984)

Public ISBD Titre : Sequencing of the packing activity in large detergent plant Type de document : texte imprimé Auteurs : K. Belarbi, Auteur ; M. G. Singh, Directeur de thèse ; A. Y. Allidina, Directeur de thèse Editeur : Manchester : [s.n.] Année de publication : 1984 Importance : 56 f. Présentation : ill. Format : 30 cm. Note générale : Master of Science : Electronic engineering : University of Manchester : 1984 Bibliogr. f. 57 . Annexe [23] f Langues : Anglais (eng) Mots-clés : Packing activity Detergent plants Scheduling problem Index. décimale : Ms01384 Résumé : In this dissertation the sequencing of the packing activity subject to constraints in large detergent plants is considered and a solution is obtained using expert systems techniques. The general topology of such plants is of processing-storing-processing type. The sequencing of the packing activity is a part of an overall solution for the scheduling problem for this type of plants using novel approaches. This overall scheduling philosophy is also described in this dissertation. Sequencing of the packing activity in large detergent plant [texte imprimé] / K. Belarbi, Auteur ; M. G.
