The aeration process via injectors is used to combat the lack of oxygen in lakes due to eutrophication. A 3D numerical simulation of the resulting flow using a simplified model is presented. In order to generate the best dynamic in the fluid with respect to the aeration purpose, the optimization of the injectors location is considered. We propose to adapt to this problem the topological sensiti...

This paper presents a novel distributed batch Gaussian process upper confidence bound (DB-GP-UCB) algorithm for performing batch Bayesian optimization (BO) of highly complex, costly-to-evaluate black-box objective functions. In contrast to existing batch BO algorithms, DBGP-UCB can jointly optimize a batch of inputs (as opposed to selecting the inputs of a batch one at a time) while still prese...

The goal of this paper is to propose, empirically test and compare different logistic survival analysis techniques in order optimize the debt collection process. This process uses various actions, such as phone calls, mails, visits, or legal steps recover past due loans. We focus on soft part, where question whether when call a past-due debtor with regards expected financial return an action. p...

Abstract Due to the precision and sizing requirements of popular semiconductor devices nowadays, thickness control uniformity optimization photoresist during photolithography process are thought be critical issues for engineers consider. In this paper, parameters affecting thoroughly analyzed an economic novel approach improving spin coating is presented. Integrated Nanosystems Research Facilit...

Defects of the roll forming process are affected by amount and situation of the strains distribution. The effect of the process parameters on the strain distribution in the round cross section roll forming process has been studied. Finite element and response surface method have been used for process modelling. Then desirability functions approach and overlaid counter plots have been employed f...
