Adaptive vehicle following control system with variable time headways
(2005)In this paper, we design a vehicle following control system with variable time headways, using adaptive control design methodology. It is shown that the designed vehicle following control system guarantees closedloop ...

Asymptotically optimal AR spectral estimate for multistep prediction
(2000)This paper discusses the concept of asymptotic optimality from the frequency domain point of view making use of the direct method for multiple prediction. In particular, it is shown that with the use of a new autoregressive ...

Certain results concerning filtering and control of diffusions in small white noise
(IEEE, 1997)The purpose of this talk is twofold. First, we examine in detail the binary hypothesis decision and/or estimation problem using a risksensitive cost criterion, when the state and observation processes are diffusion signals. ...

Article
Comparing Different Classifiers for Automatic Age Estimation
(2004)We describe a quantitative evaluation of the performance of different classifiers in the task of automatic age estimation. In this context, we generate a statistical model of facial appearance, which is subsequently used ...

Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation
(2008)The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...

Article
Delayed observers for linear systems with unknown inputs
(2007)We present a method for constructing reducedorder state observers for linear systems with unknown inputs. Our approach provides a characterization of observers with delay, which eases the established necessary conditions ...

Directly computable L2 and Lx performance bounds for Morse's dynamic certainty equivalence adaptive controller
(1995)In this paper we consider a model reference adaptive control scheme where the classical error augmentation and standard tuning error normalization are avoided through the use of Morse's high order tuner. We consider the ...

Failure management in Grids: The case of the EGEE infrastructure
(2007)The emergence of Grid infrastructures like EGEE has enabled the deployment of largescale computational experiments that address challenging scientific problems in various fields. However, to realize their full potential, ...

Fuzzy logic congestion control in TCP/IP differentiated services networks for quality of service provisioning
(2004)A two class Fuzzy Explicit Marking (FEM) controller was designed and used in Differentiated Services Networks for quality of service provisioning. The fuzzy control system is designed to regulate the queues of IP routers ...

An indirect adaptive control design with antiwindup compensation: Stability analysis
(2007)We combine an adaptive law with a control design including a Linear Quadratic (LQ) controller and a Linear Matrix Inequality (LMI) based antiwindup compensator using the certainty equivalence principle for asymptotically ...

Article
A new linear adaptive controller: Design, analysis and performance
(2000)The certainty equivalence and polynomial approach, widely used for designing adaptive controllers, leads to "simple" adaptive control designs that guarantee stability, asymptotic error convergence, and robustness, but not ...

Article
Nonparametric Maximum Entropy
(1993)The standard maximum entropy method of Burg and the resulting autoregressive model has been widely applied for spectrum estimation and prediction. A generalization of the maximum entropy formalism in a nonparametric setting ...

A note on the convergence rate of the finite element method for singularly perturbed problems using the Shishkin mesh
(2003)We consider the numerical approximation of singularly perturbed problems by the h version of the finite element method on a piecewise uniform, Shishkin mesh. It is well known that this method yields uniform approximations, ...

Article
On efficient AR spectral estimation for longrange predictions
(2005)This article discusses the concept of asymptotic efficiency from the frequency domain point of view making use of the direct method for multiple prediction. In particular, it is shown that with the use of a new autoregressive ...

On the capacity of a class of MIMO channels subject to normed uncertainty
(2008)The compound capacity of uncertain MIMO channels is considered, when the channel is modeled by a class described by an induced norm constraint. Within this framework, two types of classes are investigated, namely, additive ...

Article
On the effect of misspecifying the density ratio model
(2006)The density ratio model specifies that the loglikelihood ratio of two unknown densities is of known linear form which depends on some finite dimensional parameters. The model can be broadened to allow for msamples in a ...

Optimization of Stochastic Uncertain Systems: Large Deviations and Robustness
(2003)This paper is concerned with an abstract formulation of stochastic uncertain control systems, in which the payoff is described by the relative entropy between the nominal measure and the uncertain measure, while the ...

Performance improvement versus robust stability in model reference adaptive control
(Publ by IEEE, 1992)The mean square tracking error criterion and the L∞ tracking error bound criterion are used to assess the performance of a standard robust model reference adaptive control schemes in ideal and nonideal situations. Controller ...

Prediction of rainfall rate based on weather radar measurements
(2004)Weather radars are used to measure the electromagnetic radiation backscattered by cloud raindrops. Clouds that backscatter more electromagnetic radiation consist of larger droplets of rain and therefore they produce more ...

Probabilistic failure diagnosis in finite state machines under unreliable observations
(2006)In this paper we develop a probabilistic methodology for calculating the likelihood that an observed, possibly corrupted event sequence was generated by two (or more) candidate finite state machines (FSMs) (one of which ...
