web search engines are one of the most popular tools on the internet which are widely-used by expert and novice users. constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. query expansion is a way to reduce this concern and increase user satisfaction. in this paper, a new method of query expa...

The fractional parentage expansion method is extended from SU(2) nonrelativistic to SU(3) and relativistic dibaryon calculations. A transformation table between physical bases and symmetry bases for the SU (3) dibaryon is provided. A program package is written for dibaryon calculation based on the fractional parentage expansion method.

The major aim of this article is modeling of nonlinear systems with friction structure that, thismethod is essentially extended based on taylore expansion polynomial. So in this study, thetaylore expansion was extended in the generalized form for the differential equations of the statespaceform. The proposed structure is based on multi independent variables taylore extended.According to the pro...

we have designed a new type of optical channel drop filter (cdf) based on two dimensionaltriangular lattice photonic crystals. cdf operation is based on coupling to the photonic crystalwaveguide. the proposed structure is optimized to work as a cdf for obtaining the cdfcharacteristics and band structure of the filter the finite difference time domain (fdtd) method andplane wave expansion (pwe) ...

Pair production of W bosons constitutes an important background to Higgs boson and new physics searches at the Large Hadron Collider LHC. We have calculated the loop-induced gluon-fusion process gg → W W ∗ → leptons, including intermediate light and heavy quarks and allowing for arbitrary invariant masses of the W bosons. While formally of next-to-next-to-leading order, the gg → W W ∗ → leptons...

The presence of different immunoglobulins (lgG, IgM, and IgA) was studied in 50 routinely fixed paraffin embedded renal biopsies. lgG deposits was seen independently in 26 (52%) cases, in combination with IgA in 14 (28%) cases, with IgM in 1 (2%) case and with both lgA/lgM in 1 (2%) case. lgA alone was seen in 1 (2%) case only. IgM was seen only in 2 (4%) cases. In one case it was seen in combi...

We present a novel statistical model, the generalized-Gaussian-Rician (GG-Rician) distribution, for characterization of synthetic aperture radar (SAR) images. Since accurate models lead to better results in applications such as target tracking, classification, or despeckling, characterizing SAR images various scenes including urban, sea surface, agricultural is essential. The proposed model bas...

In this article, we give the extended trial equation method for solving nonlinear partial differential equations with higher order nonlinearity. By use of this method, the exact travel-ing wave solutions including soliton solution, singular soliton solutions, rational function solution and elliptic integral function solution to one-dimensional general improved KdV (GIKdV) equation and Rðm; nÞ e...
