This paper deals with a tool developed to support training and education in the field of security and safety in work areas, plants, or industrial environments. The tool comprises the dashboards enabling administrators and users to simulate risks and accidents to be ready for interventions in case of occurrence. Based on a computational model of risks, able to identify the causes and the signs w...

This article presents an algorithm for constructing orthogonal Latin hypercubes, given a fixed sample size, in more dimensions than previous approaches. In addition, we detail a method that dramatically improves the space-filling properties of the resultant Latin hypercubes at the expense of inducing small correlations between the columns in the design matrix. Although the designs are applicabl...

Amine is one of candidate solvents that can be used for CO2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO2 recovery plant for post-combustion CO2 removal. For each amine solvent, ...

This paper presents results obtained from simulating a service system with process oriented simulation methodology. To make the service system responsive and efficient, the SCOR modeling idea is incorporated to build the simulation model. Awesim is a process oriented simulation modeling methodology and so is the Supply Chain Operations Reference (SCOR), developed by supply chain council. A dent...

Models for mixtures of ingredients are typically tted by Schee e's canonical model forms. An alternative representation is discussed which ooers attractive symmetries, compact notation and homogeneous model functions. It is based on the Kronecker algebra of vectors and matrices, used successfully in previous response surface work. These alternative polynomials are contrasted with those of Schee...

Many multivariate functions in engineering models vary primarily along a few directions in the space of input parameters. When these directions correspond to coordinate directions, one may apply global sensitivity measures to determine the most influential parameters. However, these methods perform poorly when the directions of variability are not aligned with the natural coordinates of the inp...

A methodology is proposed to jointly model treatments with quantitative levels measured throughout time by combining the response surface and growth curve techniques. The model parameters, which measure the effect throughout time of the factors related to the second-order response surface model, are estimated. These estimates are made through a suitable transformation that allows to express the...

We present the calibration of a mobility model for a 0.25μm CMOS technology using response surface methodology. For this process several measurements for different gate lengths (0.2μm 4.0μm) were made. Care was taken to eliminate the statistical variations typical to sub-micron devices by measuring several chips on the the same wafer and taking an average sample.

Octenyl succinic anhydride (OSA) modified early Indica rice starch was prepared in aqueous slurry systems using response surface methodology. The paste properties of the OSA starch were also investigated. Results indicated that the suitable parameters for the preparation of OSA starch from early Indica rice starch were as follows: reaction period 4 h, reaction temperature 33.4 °C, pH of reactio...
