Injection molding is an iterative manufacturing process entailing low operational costs. Quality control plays an important role in this process. To improve the efficiency of quality control measures, we propose a model-free optimization (MFO) method as a replacement for traditional model-based techniques. The simplex search method is incorporated in the MFO, and part weight and dimension are separately...
Phase problems arise from lost phase information in measurement of diffraction waves. The missing phase should be retrieved to reconstruct an object image from the diffraction pattern. This paper proposes a hybrid type approach, Evolutionary-based GS (E-GS), based on the Gerchberg - Saxton algorithm (GS algorithm) and Evolutionary Multicriterion Optimisation (EMO). There are three main aims of E-GS:...
Unitary space-time constellation design is considered for noncoherent multiple-antenna communications, where neither the transmitter nor the receiver knows the fading coefficients of the channel. By employing the Clarke's subdifferential theorem of the sum of the kappa largest singular values of a unitary matrix, we present a numerical optimization procedure for finding unitary space-time signal constellations...
