چکیده

This paper presents a method to model the deformation of an elastic object with an artificial neural network. The neural network is trained directly from images of the elastic object deforming under known loads. Using this process, models can be created for objects such as biological tissues that cannot be modeled by existing techniques. The neural network elastic model is used in conjunction with a deformable template matching algorithm to perform vision-based force measurement (VBFM). We demonstrate this learning method on objects with both linear and nonlinear elastic properties.

Application of Scanning Electron and Atomic Force Mode Microscopy on inscription from Proto-Elamite period in Tappeh Sofalin

The study of cultural heritage artifacts and the research of a protection and restoration intervention create with - and are often limited to - a complete characterization of their surface. This is not only factual for museum objects, but also for archaeological artifacts, because the object as it was discovered may contain precious unknown information that could be lost by too much aggressive ...

Yarn tenacity modeling using artificial neural networks and development of a decision support system based on genetic algorithms

Yarn tenacity is one of the most important properties in yarn production. This paper addresses modeling of yarn tenacity as well as optimally determining the amounts of the effective inputs to produce yarn with desired tenacity. The artificial neural network is used as a suitable structure for tenacity modeling of cotton yarn with 30 Ne. As the first step for modeling, the empirical data is col...
