#### The concept of confluence and the edge conditions for a wedge bounded by material sheets

(IEEE, 2000)

The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges, in analytical studies they ...

#### Modulation of non-linear axial and transverse waves in a fluid-filled thin elastic tube

(Pergamon-Elsevier Science, 2000-07)

In the present work, utilizing the non-linear equations of a pre-stressed thin elastic tube filled with an incompressible inviscid fluid the propagation of weakly non-linear waves in such a medium is studied. Considering ...

#### Generation of optimum signature base sequences for speech signals

(IEEE, 2000)

In our previous publications [1-6], we proposed a novel method to represent signals in terms of, so called, "Signature Base Functions-SBF' which were extracted from the physical features of the waveform under consideration. ...

#### A generalization of the Wiener-Hopf approach to direct and inverse scattering problems connected with non-homogeneous half-spaces bounded by n-part boundaries

(Oxford Univ Press, 2000-08)

The classical Wiener-Hopf method connected with mixed two-part boundary-value problems is generalized to cover n-part boundaries. To this end one starts from an ad-hoc representation for the Green function, which involves ...

#### The boundary layer approximation and nonlinear waves in elastic tubes

(Pergamon-Elsevier Science, 2000-09)

In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and approximate equations of an incompressible viscous fluid, the propagation of weakly nonlinear waves is examined. ...

#### Scattering of electromagnetic waves by a rectangular impedance cylinder

(Elsevier Science, 2000-04)

A uniformly valid asymptotic solution is developed for the diffraction of a high-frequency wave by an infinitely long rectangular cylinder having different impedance walls. The incident wave is generated by a line source ...

#### On the contribution of higher order terms to solitary waves in fluid filled elastic tubes

(Birkhauser Verlag, 2000-01)

In the present work, employing the nonlinear equations of an incompressible, isotropic and elastic thin tube and the approximate equations of an incompressible inviscid fluid, the propagation of weakly nonlinear waves, in ...

#### A method for higher-order expansion in non-linear ion-acoustic waves

(Pergamon-Elsevier Science, 2000-03)

The basic equations describing the non-linear ion-acoustic waves in a cold collisionless plasma, in the longwave limit, is re-examined through the use of a modified multiple-scale expansion method. Expanding the field ...

#### Calculation of the T-X phase diagram for a mixture of liquid crystals

(Pergamon-Elsevier Science, 2000-12)

In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. ...

#### Joint ML timing and phase estimation in OFDM systems using the EM algorithm

(IEEE, 2000)

In this paper, a computationally efficient algorithm is presented for joint maximum likelihood (ML) timing and carrier phase estimation of OFDM systems employing M-PSK modulation scheme with additive Gauissian noise, based ...
