Two polypyridyl copper(II) complexes, [Cu(phen)(phen-dione)Cl]Cl (1) and [Cu(bpy) (phen-dione)Cl]Cl (2), (where Phen =1,10-phenanthroline, bpy =2,2'-bipyridine and Phen-dione = 1,10-phenanthroline-5,6-dione), were used as efficient catalysts for the oxidation of benzyl alcohol to benzaldehyde. The effects of various parameters such as reaction temperature, reaction time, etc. were studied. The ...

In this paper, we present a global state feedback tracking controller for underactuated surface marine vessels. This controller is based on saturated control inputs and, under an assumption on the reference trajectory, the closed-loop system is globally asymptotically stable (GAS). It has been designed using a 3 Degree of Freedom benchmark vessel model used in marine engineering. The main featu...

A learning automaton systematically updates a strategy to enhance the performance of a system output. The authors apply, a variable-structure learning automaton to achieve a best compromise solution between the economic operation and stable operation in a power system when the loads vary randomly. Both the generation cost for economic operation and the modal performance measure for stable opera...
