The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...

In this paper, the homotopy perturbation method (HPM) is considered for finding approximate solutions of two-dimensional viscous flow. This technique provides a sequence of functions which converges to the exact solution of the problem. The HPM does not need a small parameters in the equations, but; the perturbation method depends on small parameter assumption and the obtained results. In most ...

This paper describes the outcomes of a study that the EDMANS(**) group has recently performed in a rubber extrusion process, focusing on the knowledge discovery phase previous to the system modeling. Some of the tools developed to satisfy the special needs of such a process are also presented: the CiTree algorithm for clustering subpopulations in massive databases and the PAELLA algorithm for o...

Abstract Numerical optimisation is applied to rod extrusion in order generate optimal parameter sets which result reduced damage accumulation. A brief overview of academic applications for given. Their restrictions are reflected upon, leading the proposed framework utilising commercial software Abaqus FEA, enables industrial problems with frictional contact. The setup modularly enable arbitrary...

Al-SiC composites are among the most demanding metal matrix composites due to their excellent strength, good ductility, good corrosion resistance, low coefficient of thermal expansion and reasonable price. Manufacturing of cast metal matrix composites usually involves some problems such as inhomogeneous distribution of the particles due to poor wetability of ceramics to molten alloys, porosity ...
