industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...

In this paper, we set up a framework to deal with nonlinear distortions in a linear modeling framework. The nonlinear system is replaced by a linear system plus a noise source. The properties of this representation are given and a measurement technique to extract the linear model and the noise variance is developed. Eventually, the different aspects of this approach are discussed from a measure...

This work considers the characterization of linear PVC acoustic properties using a linear ultrasonic measurement technique and the non-collinear ultrasonic wave mixing technique for measurement of the physical ageing state in PVC. The immersion pulse-echo measurements were used to evaluate phase velocity dispersion and attenuation of longitudinal waves in PVC test specimens. The suggested nonco...
