In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...

Spiking activity from neurophysiological experiments often exhibits dynamics beyond that driven by external stimulation, presumably reflecting the extensive recurrence of neural circuitry. Characterizing these dynamics may reveal important features of neural computation, particularly during internally-driven cognitive operations. For example, the activity of premotor cortex (PMd) neurons during...

We investigate by scattering techniques the structure of water-based soft composite materials comprising a crystal made of Pluronic block-copolymer micelles arranged in a face-centered cubic lattice and a small amount (at most 2% by volume) of silica nanoparticles, of size comparable to that of the micelles. The copolymer is thermosensitive: it is hydrophilic and fully dissolved in water at low...

We show that the problem of nding a maximum renamable Horn problem within a propositional satis ability problem is NP hard but can be formulated as a set packing and therefore a maximum clique problem for which numerous algorithms and heuristics have been developed

This work is a modeling of evolutionary networks embedded in one or two dimensional configuration space. The evolution is based on two attachments depending on degree and spatial distance. The probability for a new node n to connect with a previous node i at distance r ni follows a k i  j k j + (1 − a) r −α ni  j r −α nj , where k i is the degree of node i, α and a are tunable parameters. In ...

To understand a discourse the reader needs to recover the relations between the discourse elements as intended by the writer Writers can and very often do help the reader along by providing explicit lexical signals of the intended discourse relations through the use of lexicalised discourse markers In this paper we present a novel approach for generating texts containing multiple embedded rheto...

There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...

The AGV (automated guided vehicle) was introduced in UK in 1953 for transporting. But nowadays, due to their high efficiency, flexibility, reliability, safety and system scalability, they are used in various application in industries. In brief, the AGV robot is a system which typically made up of vehicle chassis, embedded controller, motors, drivers, navigation and collision avoidance sensors, ...

Embedded noun phrase structures are frequently used in the Japanese language because embedded sentences make modified noun phrases more expressive. In embedded noun phrase structures, a noun phrase modified by an embedded sentence is usually created by extraposing the case, such as the subjective case, of the sentence. In contrast, there is another type of embedded noun phrase structure. In thi...
