his article addresses thermal feedback control of T distributed-parameter, dynamic nonlinear heat transfer phenomena involved in rapid prototyping processes. These mechanisms are captured in a numerical simulation of the thermal field generated during such operations. For the design of a multivari-able controller, a linearized state-space model of lumped(More)

ABSTRACT Polymeric composites have gone through a level of maturity beyond the laboratory stage with the development of the Boeing 787, the structure of which contains more than 50% composites. Nonetheless, a basic understanding of the(More)
γ-Al(2)O(3) is a well known catalyst support. The addition of Ce to γ-Al(2)O(3) is known to beneficially retard the phase transformation of γ-Al(2)O(3) to α-Al(2)O(3) and stabilize the γ-pore structure. In this work, Ce-doped γ-Al(2)O(3) nanowires have been prepared by a novel method employing an anodic aluminium oxide (AAO) template in a 0.01 M cerium(More)
Selective laser sintering (SLS) is an additive rapid manufacturing technique where a high-power laser is used to fuse micro-and nano-particles into a specified three-dimensional geometry. The goal of this work was to develop an analytical model for the SLS manufacturing process in order to control the geometrical characteristics of the sintered areas when(More)
