This paper describes our use of Prolog Word Experts (PWEs) in the Senseval-2 competition. We explain how we specify our PWEs as sequences of transformation rules and how they can be trained on sense tagged corpus data. We give a semantics of PWEs by translating them into first order predicate logic, and we describe how PWEs can be compiled into Prolog procedures. We finally present our results ...

The quasistatic limit of the antiplane shear-wave speed (effective speed) c in 2D periodic lattices is studied. Two new closed-form estimates of c are derived by employing two different analytical approaches. The first proceeds from a standard background of the plane wave expansion (PWE). The second is a new approach, which resides in x space and centers on the monodromy matrix (MM) introduced ...

Effective anti-plane quasistatic moduli for 2D piezoelectric phononic crystals of arbitrary anisotropy are formulated analytically using the plane-wave expansion (PWE) method and the recently proposed monodromy-matrix (MM) method. The latter approach employs Fourier series in one dimension with direct numerical integration along the other direction. As a result, the MM method converges much qui...

(paraxial wave equation) in bipolar coordinate system. A new type of exact solution of the reduced 3 dimensional spatial PWE (paraxial wave equation) for the case of bipolar coordinates is presented here. First, we consider a self-similar representation of the solution in a bipolar coordinate system, the second we additionally reduce PWE under a proper paraxial assumption. Analyzing the structu...

The band structure of two-dimensional chalcogenide glass photonic crystal of triangular lattice structure is calculated at terahertz frequencies using Plane Wave Expansion Method. The band gap ratio was found to vary with variation of the structural parameters such as fill factor and dielectric contrast. The spatial asymmetry associated with lattice structure gives rise to a complete photonic b...

The plane wave expansion method for calculating photonic bandgap structures is reformulated by using the method of Fourier factorization with complex polarization bases. A brief description of the method is shown, and then two examples of photonic crystals are calculated, one with square and another with hexagonal periodicity of arranged elements. The convergence of the presented approach is di...

In this paper, to generate slow light with large group index, wideband, and low dispersion in suggested line defect photonic crystal waveguide, a systematic optimization procedure is performed. Two structural parameters in the adjacent rows of the waveguide are carefully adjusted. Dispersion engineering in the proposed structure is done by using plane wave expansion method. By tuning the struct...
