DAMAGE IDENTIFICATION BY USING MODAL EXPANSION AND TOPOLOGY OPTIMIZATION IN THREE DIMENSIONAL ELASTICITY PROBLEMS
In this paper, topology optimization is utilized for damage detection in three dimensional elasticity problems. In addition, two mode expansion techniques are used to derive unknown modal data from measured data identified by installed sensors. Damages in the model are assumed as reduction of mass and stiffness in the discretized finite elements. The Solid Isotropic Material with Penalization (...
متن کاملA topology control algorithm for autonomous underwater robots in three-dimensional space using PSO
Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...
متن کاملMechanical performance of three-dimensional bio- nanocomposite scaffolds designed with digital light processing for biomedical applications
Introduction: The need for biocompatible and bioactive scaffolds to accelerate the regeneration and repair of fractured bones has been considered for bone tissue engineering applications during recent decades. The new methods were developed to produce scaffolds to improve the tissue quality, size of cavities, control the porosity and increase the scaffold compressive strength u...
متن کاملDigital Holography and Three Dimensional Imaging (DH)
We have investigated the image type full-color computer-generated hologram that has full parallax and can be reconstructed with three color LEDs. The object of the hologram is processed from 3D computer graphics polygon data and has shaded surface with hidden surface removal. The optical reconstructed image from the printed hologram is evaluated. © 2011 Optical Society of America OCIS codes: 09...
متن کاملFundamentals of Three-dimensional Digital Image Processing
This book is a detailed description of the basics of 3-dimensional (3D) digital image processing, in particular the processing of images from techniques such as CT, MRI, and nuclear emission tomography. The book is based on 1980s research by the first author, Dr. Toriwaki, at Nagoya University and Chukyo University, Japan. The targeted audience is primarily graduate students and scientists in b...
