Adaptive Kalman receiver for OFDM systems with transmit diversity in mobile wireless channels
(Walter De Gruyter GMBH, 2004-12)
A new joint channel tracking and symbol detection scheme is proposed in this paper for pilot symbol assisted transmit diversity OFDM systems by exploiting the correlation of the adjacent subchannels. Modelling the channel ...
The dynamic response of an incompressible non-linearly elastic membrane tube subjected to a dynamic extension
(Pergamon-Elsevier Science Ltd, 2004-06)
The dynamic response of an isotropic hyperelastic membrane tube, subjected to a dynamic extension at its one end, is studied. In the first part of the paper, an asymptotic expansion technique is used to derive a non-linear ...
Global existence and nonexistence results for a generalized Davey-Stewartson system
(IOP Publishing, 2004-12-03)
We consider a system of three equations, which will be called generalized Davey-Stewartson equations, involving three coupled equations, two for the long waves and one for the short wave propagating in an infinite elastic ...
An essential approach to the architecture of diatomic molecules. 2. How size, vibrational period of time, and mass are interrelated?
(Nauka/Interperiodica, 2004)
In our previous article, we arrived at an essential relationship for T the classical vibrational period of a given diatomic molecule, at the total electronic energy E-, i.e., T = [4pi(2)/(rootn(1)n(2)h)] rootgM(0)m(e) R-2, ...
A new theory of complex rays
(Oxford Univ Press, 2004-12)
A new approach to the theory of complex rays is presented. It is shown that the three-dimensional Minkowski space, the variant of the well known four-dimensional space-time Minkowski space of the special theory of relativity, ...
Elucidation of the complete set of H-2 electronic states' vibrational data
(Pergamon-Elsevier Science Ltd, 2004-11)
We have previously established that, the vibration period T of a diatomic molecule, can be expressed as T = [4pi(2)/(rootninjh)]rootgM(0)m(e)r(2), where M-0 is the reduced mass of the nuclei, M-e the mass of the electron, ...
A model of AlN layer formation during ion nitriding of Al
(Springer-Verlag, 2004-11)
A diffusion model of AlN layer formation by ion nitriding of Al is proposed based on the analysis of atomic transport during the process. This model is reduced to the following. Implantation of N ions to the surface of the ...
Immitance data modelling via linear interpolation techniques: a classical circuit theory approach
(Wiley-Blackwell, 2004-11)
With the advancement of the manufacturing technologies to produce new generation analog/digital communication systems, immitance data modelling has gained renewed importance in the literature. Specifically, models are ...
Amplitude modulation of nonlinear waves in a fluid-filled tapered elastic tube
(Elsevier Science Inc, 2004-07-15)
In the present work, treating the arteries as a tapered, thin walled, long and circularly conical prestressed elastic tube and using the reductive perturbation method, we have studied the amplitude modulation of nonlinear ...
Forward-viewing CMUT arrays for medical Imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2004-07)
This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ...
