Objective: To evaluate marginal discrepancies between cast implant superstructure and EDM processed implant structure. Materials and methods: For the purpose of this study, an experimental model was prepared on which nine cast implant superstructure in nickel-chromium were fabricated which was then subjected to EDM processing. One-screw test was used to verify fit of superstructure both preand ...

Benefiting from the improved resolution and polarization information of SAR data, ship recognition has attracted much attention during the last decade. This paper considers the ship recognition in TerraSAR-X imagery. We propose a novel feature extraction algorithm, named Superstructure Scattering Distribution (SSD), by investigating the ship’s superstructure and corresponding electromagnetic sc...

We report on the self-organized growth of a regular array of Fe nanoclusters on a nanopatterned magnetite surface. Under oxidizing preparation conditions, the s111d surface of magnetite exhibits a regular superstructure with three-fold symmetry and a 42 Å periodicity. This superstructure represents an oxygen-terminated s111d surface, which is reconstructed to form a periodically strained surfac...

We describe methodology for producing highly uniform, ordered and reproducible superstructures of surfactant-coated ZnS nanorod and nanowire assemblies, and propose a predictive multiscale ‘‘packing model’’ for superstructure formation based on electron microscopy and powder X-ray diffraction data on the superstructure, as well as on individual components of the nanostructured system. The studi...

Networks C. A. Schweiger and C. A. Floudas1 Department of Chemical Engineering, Princeton University, Princeton, NJ 08544-5263, USA Abstract{The synthesis of optimal reactor networks using a superstructure based approach is considered. The fundamental units in the superstructure are the continuous stirred tank reactor (CSTR) and a cross ow reactor (CFR). The mathematical modeling leads to an op...

The objective of this contribution is to propose a multilevel-hierarchical approach to the MINLP synthesis of process flowsheets. Following a hierarchical strategy, the designer can postulate the superstructure at different levels of representation of flowsheet alternatives and model it at the corresponding level of aggregation and complexity. By the use of the prcscrcening procedure the supers...

Fiber Reinforced Polymer (FRP) bridge systems are gaining wide acceptance among bridge engineers. At the same time, FRP bridge systems are relatively expensive when compared to traditional reinforced concrete bridge systems. In this study, the concept of the hybrid FRP-concrete structural systems is applied to a bridge superstructure. The hybrid FRP-concrete superstructure system is intended to...

Surface-enhanced Raman scattering (SERS) substrates with high density and uniformity of nanogaps are proven to enhance the reproducibility and sensitivity of the Raman signal. Up to now, the syntheses of a highly ordered gold or silver superstructure with a controllable nanoparticle size and a well-defined particle gap have been quite limited. Here, we reported an ordered mesoporous silver supe...
