PERSPIRATION of the stump while a prosthesis is being worn has always been a problem to a sizable segment of the amputee population. As a rule, amputees perspire at a greater rate than is normal even without the prosthesis. The newer, total-contact sockets as designed and introduced offer no provision for ventilation. Although in the case of some patients who sweat profusely during the initial ...

Operations Research Transforms Baosteel's Operations

Operations research in BASF's supply chain operations

In this article we highlight the application of Operations Research (OR) at BASF in the area of supply chain management (SCM) through the use of selected examples with annual cost savings ranging between several hundred thousand and several million e. We address special characteristics of the process industry that have to be dealt with and identify future research needs. The examples cover stra...

Some Applications of Semidefinite Optimization from an Operations Research Viewpoint

Annals of Operations Research

This study compares the predictive performance of three neural network methods, namely the Learning Vector Quantization, the Radial Basis Function, and the Feedforward network that uses the conjugate gradient optimization algorithm, with the performance of the logistic regression and the backpropagation algorithm. All these methods are applied to a dataset of 139 matched-pairs of bankrupt and n...
