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...

Explaining the Methods of Architecture Representation Using Semiotic Analysis (Umberto Eco's Theory of Architecture Codes)

: In this paper, it is tried to explain the concept of representation and architectural representation through a qualitative methodology, approach its procedure for gradual creation in architecture and then according to scholars and to obtain the effect of this concept in the process of architectural facts the concepts are presented. In addition, it is referred to theories and practical texts b...

State-Space Representation of Instationary Two-Dimensional Airfoil Aerodynamics

In the aero-elastic analysis of wind turbines based on blade element theory, the need to include a model of the local, two-dimensional instationary aerodynamic loads, commonly referred to as dynamic stall has become obvious in the last years. In this contribution we describe an alternative choice for such a model, based on [19]. Its derivation is governed by the flow physics, thus enabling inte...

The Representation of Three-Dimensional Space in Fish

In mammals, the so-called "seat of the cognitive map" is located in place cells within the hippocampus. Recent work suggests that the shape of place cell fields might be defined by the animals' natural movement; in rats the fields appear to be laterally compressed (meaning that the spatial map of the animal is more highly resolved in the horizontal dimensions than in the vertical), whereas the ...
