in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...

Nowadays, distributed computer systems have become very popular approach of computing as it delivers high end performance at a low cost. In a distributed computing environment, autonomous computers are connected by means of a communication network, arranged in a geometrical shape called network topology. In the present paper a detailed study of network topologies is done for the distributed com...

Time-dependent modeling of controlled opto-mechanical systems (e.g. astronomical telescopes) is part of the VLTI system engineering work at ESO. For creation of optical models to be integrated within a dynamic Matlab/ Simulink ® simulation, a novel optical modeling tool has been developed. It offers a versatile set of geometrical and wave optical propagation algorithms each with its specific st...

The paper deals with a novel approach to modeling heterogeneous objects. A controlling-vertex -based algorithm for materials information incorporation is proposed and constructed. In this algorithm, the controlling vertices with material information and geometrical information are selected as the gradient references first, and then the material information at any other points in the model space...

This paper shortly describes Blender 3D modification and its use for the design of mechanical parts. The 3D modification of the Blender modeling system and experiments made brought interesting results especially from the human-computer interaction field. The modification relies on the stereoscopy based devices which are currently available at the market. However, the stereoscopy has some drawba...

There has been little interest in the application of hydraulic fracture treatment in Iranian oil fields, thanks to the primarily suitable production rates of the vast oil fields. In this paper, hydraulic fracturing treatment was simulated by different models for a carbonate reservoir in the southwest of Iran. Suitable pay zones were nominated based on the lithology, water-oil saturation, geomec...

Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...
