Hard turning has been recognized as a substitute for abrasive-based processes due to its operational flexibility, economic benefit, and low environmental impact. Besides these advantages, hard turning can induce compressive residual stresses, which increase the fatigue life of the workpiece. In this

The optimal control of a class of linear deterministic time-invariant multi-dimensional distributed systems is considered. The unconstrained optimal control problem is formulated as a quadratic minimisation in a real Hilbert space. A conjugate gradient minimisation technique is employed in its solut
Optimization of three parameters (incubation temperature, initial substrate moisture and inoculum size) was attempted by using a Box-Behnken design under the response surface methodology for the optimal production of โฃ-amylase by Aspergillus oryzae NRRL 6270 in solid-state fermentation (SSF).

Some problems in optimal control, for a class of linear distributed parameter systems, are posed. By using a theorem of approximation theory, a maximum principle, which is applicable to these optimal control problems, is given. It is shown, that for the problems posed in this paper, this maximum pri
