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 simulationbased 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 quasilinear and semilinear wavetype equations
(2008)In this paper, we consider the class of wavetype 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, ...

Article
Differential invariants for thirdorder 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 timevarying longterm and shortterm fading wireless networks
(2007)In this paper, new timevarying wireless channel models that capture both the space and time variations of longterm and shortterm fading wireless networks are developed. The proposed models are based on stochastic ...

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

Article
Linearisation and potential symmetries of certain systems of diffusion equations
(2006)We consider systems of two pure onedimensional diffusion equations that have considerable interest in Soil Science and Mathematical Biology. We construct nonlocal 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 ...

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

Article
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 ...

Article
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 ...

Article
Robust adaptive control of minimum phase nonlinear 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 ...

Article
Robust switching adaptive control of multiinput 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, ...
