Quantitative three-dimensional modeling of zeotile through discrete electron tomography.
Discrete electron tomography is a new approach for three-dimensional reconstruction of nanoscale objects. The technique exploits prior knowledge of the object to be reconstructed, which results in an improvement of the quality of the reconstructions. Through the combination of conventional transmission electron microscopy and discrete electron tomography with a model-based approach, quantitativ...
متن کاملNucleation on active centers in confined volumes.
Kinetic equations describing nucleation on active centers are solved numerically to determine the number of supercritical nuclei, nucleation rate, and the number density of nuclei for formation both of droplets from vapor and also crystalline phase from vapor, solution, and melt. Our approach follows standard nucleation model, when the exhaustion of active centers is taken into account via the ...
متن کاملDislocation-precipitate Interaction in Discrete Dislocation Dynamics
This contribution deals with the numerical simulation of dislocation dynamics by means of parametric mean curvature flow. Dislocations are described as an evolving family of closed and open smooth curves driven by the normal velocity. The equation is solved using direct approach by semi-discrete scheme based on finite difference method. Numerical stability is improved by tangential redistributi...
متن کاملThree-Dimensional Modeling
A scheme used in building models of three-dimensional objects through binocular and motion parallax analyses is presented. Some preliminary results in using the models for recognition are described, and a discussion of the major objectives summarizes the rationale of the work. The principal emphasis throughout the paper will be that effective vision requires flexible, domain-free, three-dimensi...
متن کاملAnalysis and Low-order Modeling of the Three-dimensional Flow Past a Confined Square Cylinder
The laminar flow past a square cylinder symmetrically placed between two parallel walls is considered. A classical vortex wake is shed from the cylinder, but three-dimensional instabilities are present and they develop in complicated flow patterns. The possibility of extracting an accurate low-order model of this flow is explored. Key-words: low-order models, wake flows, proper orthogonal decom...
