Adaptive connection admission and flow control: quality of service with high utilisation
(IEEE, 1994)In this paper, we use adaptive feedback and adaptive feedforward control methodologies to avoid congestion at high server utilisation. This addresses the combined connection admission and flow control problem (generic ...

Classification of potential symmetries of generalised inhomogeneous nonlinear diffusion equations
(2003)We consider the class of generalised nonlinear diffusion equations f(x)ut = [g(x)unux]x which are of considerable interest in mathematical physics. We classify the nonlocal symmetries, which are known as potential symmetries, ...

Determining model accuracy as a function of inputs and system parameters
(American Society of Mechanical Engineers (ASME), 2004)Vital to the effectiveness of simulation-based design is having a system model of known quality. Previous research introduced an algorithm called AVASIM for assessing model validity systematically and quantitatively. AVASIM ...

Differential invariants for quasi-linear and semi-linear wave-type equations
(2008)In this paper, we consider the class of wave-type equations utt = f (x, t, u) uxx + g (x, t, u, ux, ut) and two special cases of it. We derive the equivalence transformations for these equations and using these transformations, ...

Differential invariants for third-order evolution equations
(2015)We consider a general class of third order evolution equations. We construct differential invariants with the employment of the infinitesimal method that using equivalence groups. We use the differential invariants to ...

Distributed stochastic power control for time-varying long-term and short-term fading wireless networks
(2007)In this paper, new time-varying wireless channel models that capture both the space and time variations of longterm and short-term fading wireless networks are developed. The proposed models are based on stochastic ...

Least-Square estimation for nonlinear systems with applications to phase and envelope estimation in wireless fading channels
(2008)This paper addresses the problem of nonlinear Least-Square estimation. A new approach is presented which employees a change of probability measure technique to derive recursive equations for conditional means of nonlinear ...

Linearisation and potential symmetries of certain systems of diffusion equations
(2006)We consider systems of two pure one-dimensional diffusion equations that have considerable interest in Soil Science and Mathematical Biology. We construct non-local symmetries for these systems. These are determined by ...

Modeling and control design for a computer controlled brake system
(IEEE, 1996)In this paper we consider the problem of modeling and control of a computer controlled brake system. The brake model is developed using a series of experiments conducted on a test bench which contains the full scale brake ...

Modeling and control design for a computer-controlled brake system
(1997)The brake subsystem is one of the most significant parts of a vehicle with respect to safety. A computer-controlled brake system has the capability of acting faster than the human driver during emergencies, and therefore ...

On linearization of hyperbolic equations using differential invariants
(2008)In this paper we consider the general class of hyperbolic equations ux t = F (x, t, u, ux, ut). We use equivalence transformations to derive differential invariants for this class and for two subclasses. Then we employ ...

On linearizing systems of diffusion equations
(2006)We consider systems of diffusion equations that have considerable interest in Soil Science and Mathematical Biology and focus upon the problem of finding those forms of this class that can be linearized. In particular we ...

Robust adaptive control of minimum phase non-linear systems
(1996)We show that an adaptive input/output feedback linearization control scheme for minimum phase nonlinear systems is robust with respect to unstructured plant uncertainties such as unmodelled dynamics and disturbances provided ...

Robust switching adaptive control of multi-input nonlinear systems
(2002)During the last decade a considerable progress has been made in the design of stabilizing controllers for nonlinear systems with known and unknown constant parameters. New design tools such as adaptive feedback linearization, ...
