This modeling is performed on an experimental data set of complexes, where the metal ions of these complexes include transition ion metals and lanthanide ion metals. We use these models to develop a series of new thiosemicarbazone and their complexes; simultaneously, the complexes are worked out the stability constants from the novel models.

The effect of machining parameters on the surface roughness in dry-turning Ti6Al4V alloy using an experimental design method was investigated. A mathematical equation based on the response surface methodology was established to fully understand the influence of machining parameters (cutting speed, feed rate, and depth of cut) on the surface roughness.

This thesis presents the following contributions. First, it is identified that disturbance estimation based networks utilised for compensation possess the same polynomial architectures as signal conditioning anti-windup and their equivalents. Next, an appropriate strategy is identified to integrate disturbance compensation for finite-controlset optimisation schemes via the constraint set rather than the cost function to maintain a simple and elegant problem structure.

(BQ) In this paper, working current, working voltage, oil pressure, spark gap Pulse On Time and Pulse Off Time on Material Removal Rate (MRR) and Surface Finish (Ra) has been studied. Empirical models for MRR and Ra have been developed by conducting a designed experiment based on the Grey Relational Analysis. Genetic Algorithm (GA) based multi-objective optimization for maximization of MRR and minimization of Ra has been done by using the developed empirical models. Optimization results have been used for identifying the machining conditions.
