Modified Gray-Level Coding Method for Absolute Phase Retrieval
Fringe projection systems have been widely applied in three-dimensional (3D) shape measurements. One of the important issues is how to retrieve the absolute phase. This paper presents a modified gray-level coding method for absolute phase retrieval. Specifically, two groups of fringe patterns are projected onto the measured objects, including three phase-shift patterns for the wrapped phase, an...
متن کاملMeasuring Absolute Arteriolar Cerebral Blood Volume (CBVa) in Human Brain Gray Matter (GM) without Contrast Agent
Introduction: Arteriolar cerebral blood volume (CBVa) is an important physiological parameter regulating tissue perfusion. We demonstrate a novel approach to measure absolute CBVa (CBVa) based on a variant of vascular-space-occupancy (VASO) MRI (1). VASO is a contrast-agent-free MRI technique that is sensitized to micro-vascular CBV changes through nulling of blood signal. Instead of the spatia...
متن کاملThe absolute structure of ptilosarcenone 2.5-hydrate, a diterpenoid briarane from the orange sea pen Ptilosarcus gurneyi (Gray)
In the title compound, C(24)H(29)ClO(8)·2.5H(2)O, which contains two organic mol-ecules (A and B) and five heavily disordered water mol-ecules in the asymmetric unit, the γ-lactone ring and the cyclo-hexenone ring are both trans-fused to the central cyclo-decene ring. The cyclehexenone ring features an α,β-unsaturated ketone with torsion angles between the conjugated carbonyl and alkene bonds o...
متن کاملA note on unique solvability of the absolute value equation
It is proved that applying sufficient regularity conditions to the interval matrix $[A-|B|,A + |B|]$, we can create a new unique solvability condition for the absolute value equation $Ax + B|x|=b$, since regularity of interval matrices implies unique solvability of their corresponding absolute value equation. This condition is formulated in terms of positive deniteness of a certain point matrix...
متن کاملON ABSOLUTE CENTRAL AUTOMORPHISMS FIXING THE CENTER ELEMENTWISE
Let G be a finite p-group and let Aut_l(G) be the group of absolute central automorphisms of G. In this paper we give necessary and sufficient condition on G such that each absolute central automorphism of G fixes the centre element-wise. Also we classify all groups of orders p^3 and p^4 whose absolute central automorphisms fix the centre element-wise.
