the role of polymeric additives such as pvp and peg is studied with respect to the morphology of pes porous layer as a sublayer of nanofiltration composite membranes based on pes/pa. results show that by phase inversionprocess of quaternary systems comprised of four components of polymer/solvent/non-solvent/additive and the diffusion of intertwined polymers some changes occur in membrane morpho...

We present a method called "Lock Release Lithography (LRL)" that utilizes a combination of channel topography, mask design, and pressure-induced channel deformation to form and release particles in a cycled fashion. This technique provides a means for the high-throughput production of particles with complex 3D morphologies and composite particles with spatially configurable chemistries. In this...

This paper presents three methods of increasing the performance of turbo codes, depending on the type of channel considered. In case of AWGN channels, a CRC aided decision criterion for the MAP algorithm is proposed. In case of RMF channels, a new chaotic channel interleaver is proposed for the bit interleaved coded modulation. For the BRMF channels, a new composite combining receiver diversity...

Introduction In this contribution, we present a multi-channel T/R coil for use in a 9.4T animal scanner system. Each coil element comprises a composite right/left-handed (CRLH) metamaterial transmission line (MTL). Eight of these elements were arranged in a circular manner to constitute a multi channel coil. MTLs offer the feature of a homogenous current distribution along the line when they ar...

Transfer of debris flow caused by floods in the river downstream of the mountains leads to several damages every year. Numerous researches have been carried out on the Mountain Rivers the results of which show the importance of performing more researches to control debris flows in the floodplain because of various effective hydraulic-geometric parameters.For this purpose, AbNik Mountain River l...

Using the analogy between dielectric breakdown and mechanical fracture, a phase-field model for dielectric damage initiation and evolution has been developed. The model utilizes a continuous field of damage variable to differentiate a localized conductive channel and the undamaged bulk material. By employing a Griffith type energy criterion for the propagation of a conductive channel, direct ha...

Abstract Entanglement transmission is utilized widely in quantum communication. In this paper we establish a model, which characterizes the performance of entanglement state passing through composite free space channel. This channel compounded with atmosphere, sea surface and underwater Based on photon pairs transmitted are simulated. Simulation results show that beam wandering, incident angle ...
