The algebraic framework introduced in [4] gives an algebraic condition for the feasibility of a set of multicast connections in a network, that is equivalent to the max-flow min-cut condition of [1]. The algebraic condition also checks the validity of a linear coding solution to a given multicast connection problem. We present two alternative formulations of this condition that are closely tied...

A technique to achieve output tracking for nonminimum phase linear systems with non-hyperbolic and near non-hyperbolic internal dynamics is presented. This approach integrates stable inversion techniques, that achieve exact-tracking, with approximation techniques, that modify the internal dynamics to achieve desirable performance. Such modification of the internal dynamics is used (a) to remove...

This paper addresses nonlinear Generalised Predictive Control (GPC) for nonlinear mechanical systems and its relationship with dynamical inversion control. First continuous-time generalised predictive control for non-linear systems is developed and the stability of the closed-loop systems is shown. It is pointed out that dynamical inversion control is a special case of continuous-time nonlinear...

The asymmetric unit of the title compound, [Ag(C(5)H(6)N(2))(2)]NO(3), consists of one and a half each of both cations and anions, the other halves being generated by crystallographic inversion centres. One of the Ag(I) atoms lies on an inversion center and one of the nitrate ions is disordered across an inversion center. Each Ag(I) atom is bicoordinated in a linear geometry by two N atoms from...

This paper presents an evaluation method for statistically based speech inversion, in which the estimated vocal tract shapes are classified into phoneme categories based on the articulatory correspondence with prototype vocal tract shapes. The prototypes are created using the original articulatory data and the classifier hence permits to interpret the results of the inversion in terms of, e.g.,...

Scatterer detection in medical ultrasound imaging can be formulated as an inverse problem concerning a linear system model based on point scatterers. The applicability of different methods of regularized inversion is examined and a novel regularization scheme specifically adapted to ultrasound imaging is introduced. The results show that standard inversion methods fail in ultrasound imaging whi...

During the last few years, the steady increase in the quantity and quality of the data concerning tsunamis has led to an increasing interest in the inversion problem for tsunami data. This work addresses the usually ill-posed problem of the hydrodynamical inversion of tsunami tide-gage records to infer the initial sea perturbation. We use an inversion method for which the data space consists of...

In this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. The results showed that change in phase density ratio had no effect on phase inversion hold-up. It also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...
