We propose an efficient method to model paper tearing in the context of interactive modeling. The method uses geometrical information to automatically detect potential starting points of tears. We further introduce a new hybrid geometrical and physical-based method to compute the trajectory of tears while procedurally synthesizing high resolution details of the tearing path using a texture base...

The performance of carbon nanotube-based transistor is analyzed. The effect of geometrical parameters on the device performance is investigated as d tunnel. We have studied the influence of the material parameters, such as the height of the SB (ΦSB), and some other physical parameters like the nanotube chirality, the gate oxide thickness and the gate oxide dielectric permittivity Our results sh...

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...

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...

An automated circuit-modeling tool is developed for arbitrary passive components. The tool builds compact, parameterized, analytical models based on full-wave EM simulations. The scattering parameters (or the transmission line parameters) of the components are stored as a multidimensional function of frequency and geometrical parameters. The modeling algorithm combines adaptive data selecting a...

geometric details is desirable in many real-world applications. We might want to know, for example, how a wall would look after adding some geometrical bumps, or how a person would look after adding wrinkles on his or her face. Direct methods for adding geometric details to an object require modeling the object and the surface details. It’s usually not a trivial task to build a 3D model for a r...
