Drilling is one of the important machining processes in hole making operations. Delamination is a vital problem during any drilling operation. It causes structural integrity reduction and poor assembly tolerance as well as potential for long-term performance deterioration. As a result, drilling of any material requires dimensional stability and interface quality. In this study, glass fibre rein...

Despite its great applicability in several industries, the combined cutting stock and lot-sizing problem has not been sufficiently studied because of its great complexity. This paper analyses the trade-off that arises when we solve the cutting stock problem by taking into account the production planning for various periods. An optimal solution for the combined problem probably contains non-opti...

This paper gives an algorithm for L-shaped linear programs which arise naturally in optimal control problems with state constraints and stochastic linear programs (which can be represented in this form with an infinite number of linear constraints). The first section describes a cutting hyperplane algorithm which is shown to be equivalent to a partial decomposition algorithm of the dual program...

Indoor localization is a challenging and important problem. Although GPS technology is very effective for outdoor localization, it cannot be used in the indoor settings, since GPS depends on line of sight to satellites. Hence, other techniques are being developed for indoor environment. Use of lasers is one option that is being investigated to perform localization and target tracking. When mult...

The ornamental stone production chain deeply changed in the ‘70s and in the following decades, when the mechanization of processes increased the production and the safety of workers. Nevertheless, the new techniques are also responsible of not negligible environmental impacts. This paper is focused on the currently most diffused techniques of extraction, cutting and polishing of the Italian sto...
