matrix analysis of corrosion inhibition phenomena (macip), in which an inhibitor isconsidered as a point in a multi-dimensional virtual efficiency space, was performed on somepyridine derivatives. the needed molecular parameters such as homo and lumo energylevels, charge densities on hetero atom, dipole moment, heat of formation, and total energyvalues were obtained by means of semi-empirical q...

In this paper, wire electrical discharge machining of D3 tool steel is studied. Influence of pulse-on time, pulse-off time, peak current and wire speed are investigated for MRR, dimensional deviation, gap current and machining time, during intricate machining of D3 tool steel. Taguchi method is used for single characteristics optimization and to optimize all four process parameters simultaneous...

in this paper we have discussed the main features of a finite clement program which we have developed for nonlinear dynamic analysis of plates and shells with material and geometric nonlinear behaviour. for this purpose, initially, the finite element model which we have used is briefly described. afterwards, the nonlinear viscoplastic material model in one-dimensional and multi-dimensional medi...

mannion and davies’ article recognises whistleblowing as an important means of identifying quality and safety issues in healthcare organisations. while ‘voice’ is a useful lens through which to examine whistleblowing, it also obscures a shifting pattern of uncertain ‘truths.’ by contextualising cultures which support or impede whislteblowing at an organisational level, two issues are overlooked...

With the development of distributed computing technology, there remain some important problems of collaborative control in distributed multi-user data sharing: heterogeneous environment, data consistency and concurrent operation. To solve the sharing issues in drilling engineering, this paper introduces a method of realizing information sharing by combining the advantages of multi-agent collabo...
