چکیده
Computational material modeling using advanced numerical techniques speeds up the design process and reduces costs of developing new engineering products. In field multiscale modeling, huge computation efforts are expected for heterogeneous materials while trying to reach high accuracy levels. this work, a machine learning approach, namely convolutional neural network (CNN), is developed as solution providing level being computationally efficient. The input CNN model consists two/three-dimensional images artificial periodic biphasic microstructures in form nonoverlapping overlapping, mono- polydisperse circular/spherical inclusion systems, which generated by random sequential inhibition process. These correspond Statistical Volume Elements (SVE). Considering linear magnetostatics at microscale, output apparent permeability SVE. Training testing data properties produced with finite element method-based two-scale asymptotic homogenization. efficiency revealed employing some representative examples two three-dimensional settings. regard, performance assessed applied computational homogenization method relating efficiency. results show predicting homogenized significant decrease time.

Edge elements for magnetostatics
Edge-elements are introduced and discussed in the context of complementarity, a desirable characteristic of numerical methods, by which solutions which are equally satisfactory as regards both fields b and h are obtained. By making the vector potential approach easier than with standard nodal elements, edge-elements enhance complementarity. We discuss comparative merits of both kinds of elements.
متن کاملBilingual Machine-Aided Indexing
Abstract The proliferation of multilingual documentation in our Information Society has become a common phenomenon. This documentation is usually categorised by hand, entailing a time-consuming and arduous burden. This is particularly true in the case of keyword assignment, in which a list of keywords (descriptors) from a controlled vocabulary (thesaurus) is assigned to a document. A possible s...
