Higher-order, large-domain electromagnetic simulations are presented based on the finite element method (FEM), method of moments (MoM), and physical optics (PO). The simulations combine higher order geometrical modeling and higher order field/current modeling, which is referred to as double-higher-order modeling. The examples demonstrate that accurate and efficient FEM, MoM, and PO simulations ...

according to recent achievements in nano technology we can see its effects in different engineering fields. in nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose.  in this paper nano modeling for two papers is developed first understanding structure in nano and micro size and second simulati...

Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...

Many modeling techniques for geometric objects have been developed; they allow the user to create, deform, animate objects and produce complex ones from simple primitives. This paper presents a new technique which composes two 2D or 3D interpenetrating shapes by creating another one including them and having a smooth aspect. By moving into each other, composed objects fuse smoothly and naturall...

Through detailed numerical and analytical studies, we establish that the significant enhancement of thermal emission via Q matching, which has been possible in one-dimensional 1D systems only, can be extended to two-dimensional 2D systems by means of Fano resonances in the 2D system. In particular, we show the existence of essentially 1D behavior in a 2D system—a case of reduced dimensionality....

This paper explores the tilt illusion effect in the Café Wall pattern using a classical Gaussian Receptive Field model. In this illusion, the mortar lines are misperceived as diverging or converging rather than horizontal. We examine the capability of a simple bioplausible filtering model to recognize different degrees of tilt effect in the Café Wall illusion based on different characteristics ...

Hence, computer simulation is SPRAY forming is a manufacturing technique in which a useful approach to investigatingthe formationand developpartially solidified metal droplets are dispersed upon a subment of round billets. Several mathematical models have strate to produce an almost fully dense material in tonnage been developedto calculate the growth of round billets...

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...

This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...
