چکیده

The method of how to abstract reality into a two-dimensional map is already mature, but with the development of three-dimensional GIS, we have to be up against the problem how to describe the reality in a 3D means. Although there are already many 3D GIS software and systems from various corporations, the standard for 3D abstraction and description of real world is still poor. In the paper we have done some elementary research on this issue, we think that there are three key matters which should be implemented including Description

Predicting three-dimensional displacement around the tunnel and its impact on the value of Q-system

Having knowledge of stability of an underground space depends on stresses and strains around it. Creating underground tunnels leads to significant changes in the rock mass stress. Therefore, to achieve the necessary stability, stresses and deformations around the tunnel must be examined carefully. Usually, stress-strain behavior analysis is conducted in two-dimensional mode. This paper was cond...

Abstraction, desalination and recharge method to control seawater intrusion into unconfined coastal aquifers

In this study, abstraction, desalination and recharge method and SEAWAT numerical model are used to investigate seawater intrusion repulsion in a hypothetical two-dimensional coastal aquifer to understand the relation of seawater intrusion with abstraction, desalination and recharge parameters (i.e. abstraction/recharge rate, wells distance and depth). Abstraction, desalination and recharge con...

Inter-observer agreement between 2-dimensional CT versus 3-dimensional I-Space model in the Diagnosis of Occult Scaphoid Fractures

  Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures.   Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...
