Background: A high prevalence of human T-cell lymphotropic virus type 1 (HTLV-1) infection among general population in the northeast of Iran has been reported. Multi-transfused patients are known as ‘at-risk’ group for the infection. This systematic review and meta-analysis was conducted to estimate the prevalence of HTLV-1 infection among Iranian multi-transfused patients. Materials and Meth...

Visual cryptography is a kind of image encryption technology. It is characterized by the process of decryption that is overlapping the encrypted images and restores the secret by the human vision. Kafri and Keren proposed three random grid algorithms to encrypt a binary secret image in 1987. The advantage of their research is that the encrypted images with random grid will not be excessive expa...

We introduce a protocol with a reconfigurable filter system to create non-overlapping single loops in the smart power grid for the realization of the Kirchhoff-Law-Johnson-(like)-Noise secure key distribution system. The protocol is valid for one-dimensional radial networks (chain-like power line) which are typical of the electricity distribution network between the utility and the customer. Th...

A system is described for animating the motion of incompressible fluids in a computer graphics context. Borrowing techniques from [7, 3, 4, 5, 2], a technique is described for simulating fluid motion and tracking the surface boundary. An approximate solution to the Navier-Stokes equations for the motion of incompressible fluids in computed over a finite grid of coupled velocities and pressures....
