in this study, an artificial neural network was developed in order to analyze flexible pavement structure anddetermine its critical responses under the influence of standard axle loading. in doing so, more than 10000four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, andsubgrade soil were analyzed under the impact of standard axle loading. pave...

We optimize multilayered antireflective coatings for photovoltaic devices, using modern evolutionary algorithms. apply a rigorous methodology to show that given structure, which is particularly regular (i.e., essentially periodic), emerges spontaneously and systematically very broad range of conditions. The regularity the structure allows thorough physical analysis how design operates. This us ...

A social network (SN) 1 is defined as a tuple , where: V – is a not-empty set of actors representing social entities: humans, organizations, departments etc., called also vertices, nodes, vertexes, members, cases, agents, instances or points; E – is a set of directed edges (relations between actors called also arcs, connections, or ties) where a single edge is represented by a tuple ,...

The ideas of employing the unique properties of meta-materials and plasmonic media for cloaking and invisibility applications have been recently suggested and investigated by several groups [1–5], and they may find numerous applications in physics and technology. While many of the recent designs of the cloaking structures are based on the transformation optics and exact formulas [6], the origin...

In this work magnetoimpedance (MI) behaviour was studied experimentally for Fe19Ni81(175 nm)/Cu(350 nm)/Fe19Ni81(175 nm) sensitive elements deposited by rf-sputtering. A constant magnetic field was applied in plane of the sandwiches during deposition perpendicular to the Cu-lead in order to induce a magnetic anisotropy. Sandwiches with different width (w) of FeNi parts were obtained. The comple...

Saltatory impulse conduction in invertebrates is rare and has only been found in a few giant nerve fibres, such as the pairs of medial giant fibres with a compact multilayered myelin sheath found in shrimps (Penaeus chinensis and Penaeus japonicus) and the median giant fibre with a loose multilayered myelin sheath found in the earthworm Lumbricus terrestris. Small regions of these nerve fibres ...

The problem of the selecting optimal lay-up stacking polymer composite materials for load-bearing elements rear part fuselage structure is considered. comparison two approaches to design carried out. first them use multilayered material elements, angles which selected from a given discrete set, and second with continuous range variables in fabric angles. As result optimization, it shown that us...

Here, we theoretically suggest the possibility of employing a multilayered plasmonic shell as a cloak for reducing the total scattering cross section of a particle, simultaneously at different frequencies in the optical domain. By exploiting the frequency dispersion of plasmonic materials and their inherent negative polarizability, it is shown, theoretically and with numerical simulations, how ...
