Adescription is given of a laser scanning system for the acquisition of the threedimensional surface data from objects as well as their color properties. The digitized data can be stored In compact data files that can serve for the reconstruction of any vlew of the object or scene on currently available graphic workstations. Threedimensional hard reproductions are also possible from the same da...

The aim of this research is to examine the postgraduate theses on subject three-dimensional virtual environments, which one outputs rapid developments in field information technologies, software industry, and communication education, based their demographic characteristics, topics, methodology, findings section, discussion conclusion suggestions section. method document analysis, qualitative me...

If you have strong views on any matter related to ultrasound, it is highly likely you will receive a summons to write an editorial on the subject for the White Journal. This editorial is my attempt to justify my frequently expressed opinion that ultrasound is not used effectively in most departments of reproductive medicine and proper use of modern technological developments would improve the q...

Spectral Decomposition Technique based on Short-Window Discrete Fourier Transform (SWDFT) was applied to threedimensional (3D) seismic data obtained from ‘Reigh’ field, onshore Niger Delta with a view enhancing stratigraphic interpretation for geological features which are beyond resolution. Two sands units the study area were studied produce spectrally decomposedsurfaces. The result of reveale...

This paper presents a novel Neural Network application in order to estimate Air Pollutant Levels. The application considers both Pollutant concentrations and Meteorological variables. In order to compute the Air Pollutant Level the method considers three important stages. In first stage, A process to validate data information and built a threedimensional Information Feature Vector with Pollutan...

In the paper, we study mechanical behavior of a three-dimensional chiral metamaterial using numerical modeling. A feature structures is that during their uniaxial loading twisting observed along axis. rod composed 3 × 9 unit cells corresponding three orthogonal axes. The relative strain compression sample in simulation did not exceed 3.3%. was performed by finite element method threedimensional...
