A new approach to spatial analysis of motorcycle taxis activities: the case of Port-au-Prince, Haiti

Jérôme Chenal, Armel Firmin Kemajou Mbianda, Rémi Jaligot

Motorcycle taxis operate in a non-regulated, uncontrolled environment, raising public health, environmental and economic issues. Consideration of such issues requires an in-depth understanding of motorcycle taxis’ organizational and operational features. U ...

Trigonometric Interpolation Kernel to Construct Deformable Shapes for User-Interactive Applications

Michaël Unser, Daniel Andreas Schmitter, Ricard Delgado Gonzalo

We present a new trigonometric basis function that is capable of perfectly reproducing circles, spheres and ellipsoids while at the same time being interpolatory. Such basis functions have the advantage that they allow to construct shapes through a sequenc ...

Nonlinear Spectral Transformations for Robust Speech Recognition

Hervé Bourlard, Hynek Hermansky, Shajith Ikbal

Recently, a nonlinear transformation of autocorrelation coefficients named Phase AutoCorrelation (PAC) coefficients has been considered for feature extraction \cite{ikbal03}. PAC based features show improved robustness to additive noise as a result of two ...

The Fourier-spectrum of circular sine and cosine gratings with arbitrary radial phases

Isaac Amidror

The Fourier spectra of circular gratings having sine or cosine radial profiles are derived, and their particular properties are discussed. These results are then extended to the most general form of circular sinusoidal gratings, namely: circular sine or co ...

Measurement and Modeling of the Dynamic Behavior of Ag/Bi(2223) Superconducting Tapes

Martin Hasler, Bertrand Dutoit

Measurements of Ag/Bi(2223) superconducting tapes have been performed between dc and 30 KHz for under and upper critical currents, up to 2 or 3 times i(c). A fast power amplifier (100A 30KHz) has been specially built for pulsing such currents in the sample ...
