In the present study an evolutionary based optimization algorithm Differential Evolution (DE) is applied to a case study of Bisalpur project, Rajasthan, India. The objective of DE based planning model is to determine suitable cropping pattern which yields maximum net benefits. Ten different strategies (variations) of DE are analyzed with various population sizes, crossover constants and weighti...

Two of the most common defects in rotating systems are abnormal wear of the bearing bushing and bearing misalignment. The present paper introduces a new fault diagnosis model that uses artificial neural networks (ANN) in order to identify the increase of wear depth and/or the increment of the misalignment angle. Reynolds equation is solved by FEM and provides data about bearing wear and misalig...

Dans un service de 36 lits de medicine in­fantile une periode de 18 mois, 33 enfants furent hospitalises pour une affection hematologique maligne: 21 cas de leucemie aigi.ie, 1 cas de leu­cemie myeloide chronique, 2 cas de lymphomes malins, 9 cas de Hodgkin aux differents stades evolutifs.  Aucune complication neurologique ne fut observe chez les malades attaints de Hodgkin. Ia moitie des enfa...

Syndrome de la queue de cheval. A propos de 4 cas.  Les auteurs rapportent quatre observations cliniques concernat des malades dont les pre­miers symptomes se manifesterent par des al­gies longitemps considerees comme "sciatique·s".  L' etude neurologique de ces cas demontrait qu'en realite "les algies sciatiques" n'etaient que des signes mono ou pluri-radiculaires en rapport avec un syndrome...
