Improved multi-aircraft ground trajectory prediction for air traffic control

Accurate trajectory prediction plays a fundamental role in advanced air traffic control operations, because it forms the basis for (among others) conflict detection and resolution schemes. It has been demonstrated that improved trajectory prediction accura ...

Incremental Global Parameter Estimation in Dynamical Systems

Benoît Chachuat

Estimating the parameters of a dynamical system based on measurements is an important task in industrial and scientific practice. Since a model's quality is directly linked to its parameter values, obtaining globally rather than locally optimal values is e ...

Diffusion adaptive networks with changing topologies

Ali H. Sayed

daptive networks (AN) have been recently proposed to address distributed estimation problems [1]–[4]. Here we extend prior work to changing topologies and data-normalized algorithms. The resulting framework may also treat signals with general distributions ...

On the Consistency of Certain Identification Methods for Linear Parameter Varying Systems

Alireza Karimi, Roland Longchamp, Mark Edward John Butcher

The consistency of certain identification methods for Linear Parameter Varying systems is considered. More precisely, methods for the identification of SISO input-output models are analysed. In order to perform a consistency analysis the application of erg ...

Assessing the role of the uncertainty in stream-flows and system's target reliability in water resource design of a hydro power system

Roham Bakhtyar

The role of the level of reliability of meeting a desired hydropower system's firm energy yield and quantifying the uncertainty of stream-flows in design components of a hydro-electric project is assessed in this study. Sequential stream flow routing (SSR) ...

Statistical inference for olfactometer data

Anthony Christopher Davison, Ingrid Ricard

Olfactometer experiments are used to determine the effect of odours on the behaviour of organisms such as insects or nematodes, and typically result in data comprising many groups of small overdispersed counts. We develop a non-homogeneous Markov chain mod ...

Interchange turbulence in the TCV scrape-off layer

Jonathan Graves, Richard Pitts, Jan Horacek

Probe measurements of electrostatic plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak are compared with the results from two-dimensional interchange turbulence simulations. Excellent agreement is found for both the radial variation of st ...

Image super-resolution with B-Spline kernels

Loïc Arnaud Baboulaz, Pier Luigi Dragotti

A novel approach to image super-resolution is described in this paper. By modeling our image acquisition system with a Spline sampling kernel, we are able to retrieve from the samples some statistical information about the observed continuous scene before ...

Adapted Generative Models For Face Verification

Samy Bengio

It has been shown previously that systems based on local features and relatively complex generative models, namely 1D Hidden Markov Models (HMMs) and pseudo-2D HMMs, are suitable for face recognition (here we mean both identification and verification). Rec ...

Hybrid HMM/ANN and GMM Combination for User-Customized Password Speaker Verification

Hervé Bourlard

Recently we have proposed an approach for user-customized password speaker verification; in this approach, we combined a hybrid HMM/ANN model (used for utterance verification) and a GMM model (used for speaker verification). In this paper, we extend our in ...
