We study the additivity property of three multipartite entanglement measures, i.e. the geometric measure of entanglement (GM), the relative entropy of entanglement and the logarithmic global robustness. Firstly, we show the additivity of GM of multipartite states with real and non-negative entries in the computational basis. Many states of experimental and theoretical interest have this propert...

Two projected methods have been proposed to deal with the two main diiculties of the numerical solution of incompressible Stokes problems. While one method enforces the null{ divergency condition through a projection 1], the other 4] projects the solution to satisfy boundary conditions. After summarizing these two techniques, the present report shows how to combine both into an accurate, eecien...

Piecewise divergence-free nonconforming virtual elements are designed for Stokes problem in any dimensions. After introducing a local energy projector based on the and stabilization, element method is proposed problem. A detailed rigorous error analysis presented discrete method. An important property that commutes with divergence operator. With help of interpolation operator onto generalized R...

The projector is being frequently used in broad range of the photogrammetric measurements with the development of non-contact measurement in the close-range photogrammetry, because a projector can project any pattern onto the measured object for controlling and calculating. Before using a projector, the interior parameters of it have to be calibrated first. Hence, the projector calibration is a...

In this paper we proposed a method for geometric calibration of a projector. This method makes use of a calibrated camera to calibrate the projector. Since the projector works inversely with a camera i.e., it projects the image instead of capturing it, so it can be considered as a reverse camera. The projector is calibrated with the help of a calibrated camera using two types of chessboard, a p...

This paper proposes a novel method for synchronizing high frame-rate (HFR) camera with an HFR projector, using visual feedback-based synchronization algorithm streaming video sequences in real time on visible-light communication (VLC)-based system. The frame rates of the and projector are equal, their phases synchronized. A is used to mitigate complexities stabilization issues wire-based trigge...

Structured light surface scanners are usually limited to a single projector and cannot provide full profile in scan. Multiple projectors must be employed extend the imaging area over whole of imaged object. Using multiple is challenging problem due inter-projector interference which make pattern decoding hard. We describe practical approach multi-projector structured scanning based on sinusoida...

PURPOSE Digital forward and back projectors play a significant role in iterative image reconstruction. The accuracy of the projector affects the quality of the reconstructed images. Digital breast tomosynthesis (DBT) often uses the ray-tracing (RT) projector that ignores finite detector element size. This paper proposes a modified version of the separable footprint (SF) projector, called the se...
