Single-shot x-ray differential phase-contrast and diffraction imaging using two-dimensional transmission gratings.
We describe an x-ray differential phase-contrast imaging method based on two-dimensional transmission gratings that are directly resolved by an x-ray camera. X-ray refraction and diffraction in the sample lead to variations of the positions and amplitudes of the grating fringes on the camera. These effects can be quantified through spatial harmonic analysis. The use of 2D gratings allows differ...

متن کاملPrivacy Spatial and Temporal Distances in Nomadic Settelments
Human always in interaction with their social environment, have consider some degree of privacy with different purposes, for themselves, the people around them and carry out their activities. Creating privacy depends on two elements; subjective meanings that ruling the creation of privacy, and the second sentence are person available facilities. Privacy is not seen, heard, smelled and availabil...
متن کاملSpatial and Temporal Analysis of Dusty Days in Iran
Iran is one of the world's arid regions and exposed to dust particles in the air. This is important in spatial and temporal terms as well as the affects human health. In this paper a day when due to the amount of dust particles visibility reduces to 5,000 m is considered the dusty day. In the spatial and temporal analysis of dusty days 38 synoptic stations were studied. In order to conduct data...
