for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

the paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. in real-world cases, demands and transshipment costs change over the period of the time. this may lead to large cost deviation in total cost. scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...

We present an integrated design and marketing approach to facilitate the generation of an optimal robust set of product design alternatives to carry forward to the prototyping stage. The approach considers variability in both (i) engineering design domain, and (ii) customer preferences in marketing domain. In the design domain, the approach evaluates performance and robustness of a design alter...

We present a new model for studying mul-titask learning, linking theoretical results to practical simulations. In our model all tasks are combined in a single feedforward neu-ral network. Learning is implemented in a Bayesian fashion. In this Bayesian framework the hidden-to-output weights, being speciic to each task, play the role of model parameters. The input-to-hidden weights, which are sha...

We present a methodology for fitting interatomic potentials to ab initio data, using the particle swarm optimization (PSO) algorithm, needing only a set of positions and energies as input. The prediction error of energies associated with the fitted parameters can be close to 1 meV/atom or lower, for reference energies having a standard deviation of about 0.5 eV/atom.We tested ourmethod by fitti...

A systematic theoretical-approach has been made to estimate various parameters, characteristics and their optimization methods for a Josephson junction to be useful as a high-speed switching element in Josephson digital logic electronics. The dynamic response of Josephson junction has been obtained using computer simulation. Our concept of turn-on deay of Josephson junction is applied in order ...
