This paper addresses the soliton dynamics in a Toda lattice with a randomly distributed chain of masses. Applying the inverse scattering transform we derive effective equations for the decay of the soliton amplitude that ...

In an effort to promote Compton scatter tomography (CST) as an adequate modality for imaging the inner parts of large objects limited in a half-space of ℝ, we show that the standard CST can be ‘improved’ in some particular ...

In medical single-photon emission computed tomography (SPECT) imaging, we seek to simultaneously obtain the internal radioactive sources and the attenuation map using not only ballistic measurements but also first-order ...

Acoustic plane wave scattering at a vertical fault structure represents the simplest two-dimensional model of geophysical exploration that can be investigated by analytical techniques. The exact and complete solution, in ...

In an effort to deal with many ionizing radiation imaging mechanisms involving the Compton effect, we study a Radon transform on circular cone surfaces having a fixed axis direction, which is called here conical Radon ...

The complete and exact solution of the scattering of a TE mode frequency domain electromagnetic plane wave by a vertical dike under a conductive overburden has been established. An integral representation composed of ...

In this Note we obtain existence and uniqueness results for the Helmholtz equation in the half-space R-+(3) with an impedance or Robin boundary condition. Basically, we follow the procedure we have already used in the ...

The numerical application of a sequence transformation method proposed in a previous work is considered for the calculation of differential cross-sections corresponding to processes where long range interactions are ...

The recently developed technique for imaging radar scattering irregularities has opened a great scientific potential for ionospheric and atmospheric coherent radars. These images are obtained by processing the diffraction ...
