FreeFEM++ Implementation of a Shell Model Described by the Intrinsic Geometry via the Oriented Distance Function
نویسندگان
چکیده
A shell can be described via the oriented distance function, which provides a natural and simple tool to describe the geometric properties of a set and of its boundary. The advantage of this approach is the total absence of Christoffel symbols. This description is well suited for the area of smart systems, where the adaptation of the existing techniques of control theory is made easier. We shall present the implementation in FreeFEM++ of the intrinsic geometric operators and of the mechanical model, showing a test case representing the free vibrations of a circular cylinder.

Discrimination of Geological Top-Formations by their Morphology through SAR Images and via Fractal Geometry implementation in IEM Backscattering Model(Case Study: Zagros Thrust Belt)
Morphological discrimination of geological top-formations is the supplemental procedure of geological mapping; so in situ measurements to register geomorphological data are unavoidable; though due to the impassable and fault cliffs field operations to visit all areas within a geological map is almost impossible. Microwave or radar remote sensing, via synthetic aperture radar (SAR) images is cap...
متن کاملTowards constructing an Integrative, Multi-Level Model for Cognition: The Function of Semantic Networks
Integrated approaches try to connect different constructs in different theories and reinterpret them using a common conceptual framework. In this research, using the concept of processing levels, an integrated, three-level model of the cognitive systems has been proposed and evaluated. Processing levels are divided into three categories of Feature-Oriented, Semantic and Conceptual Level based o...

Introduction Statistical analysis of the data on the Earth's surface was a favorite subject among many researchers. Such data can be related to animal's migration from a region to another position. Then, statistical modeling of their paths helps biological researchers to predict their movements and estimate the areas that are most likely to constitute the presence of the animals. From a geome...
