On-line model predictive control approaches require the online solution of an optimization problem. In contrast, the explicit model predictive control moves major part of computation offline. Therefore, eMPC enables one to implement a MPC in real time for wide range of fast systems. The eMPC approach requires the exact system model and results a piecewise affine control law defined on a polyhedral...
In this study, both SEM stereoscopic technique and FIB milling method are used to characterize the morphology of PDMS bowl-shaped structure. The presented structure is created via a low-cost and high-throughput modified colloidal lithographic method. 3D reconstruction through SEM stereoscopic images is used to perform volume analysis while FIB milling is used to perform cross-sectional analysis. The...
This paper reports a process of electrodeposition of Ni into porous alumina matrix. In the proposed process, porous alumina membrane with cross linked networks was fabricated using colloidal powder processing and pressureless sintering. The dispersion conditions of aqueous alumina nanopowder suspensions were obtained by optimizing both the pH and dispersant concentration. The optimal pH of the suspension...
A new nanosphere lithography technique is presented to produce a periodic nanocavities of two sizes. The process starts by deposition of a bilayer of polystyrene microspheres on photoresist through self assembly as a mask. The spheres act as microlenses to direct UV light both to the centers of the bottom spheres and between these centers, resulting in bigger and smaller nanocavities. The appearance...
