How Does Internal Motion Influence the Relaxation of the Water Protons in LnIIIDOTA-like Complexes?

Taking advantage of the Curie contribution to the relaxation of the protons in the Tb(III) complex, and the quadrupolar relaxation of the 17O and 2H nuclei on the Eu(III) complex, the effect of the internal motion of the water molecule bound to [Ln(DOTAM)( ...

Phase AutoCorrelation (PAC) derived Robust Speech Features

Hervé Bourlard, Hemant Misra, Shajith Ikbal

In this paper, we introduce a new class of noise robust acoustic features derived from a new measure of autocorrelation, and explicitly exploiting the phase variation of the speech signal frame over time. This family of features, referred to as ``Phase Aut ...

In-door and out-door Navigation for the Blind: An integrated approach for a new product

Bertrand Merminod, Quentin Ladetto

When satellite are available, the localisation of a pedestrian is fairly straightforward. However in cities or indoors, dead reckoning systems are necessary to determine the user's position. Our current research focuses on the development of algorithms and ...

Microsystems - from technologies to products

Peter Ryser

In this paper, we outline the process leading from technologies to successful products in the MEMS (Microelectromechanical Systems) and MST (Microsystems Technology) field. The development of new products involves a lot of factors, such as mature technolog ...

Bounds for Independent Regulated Inputs Multiplexed in a Service Curve Network Element

Jean-Yves Le Boudec, Milan Vojnovic

We consider the problem of bounding the probability of buffer overflow in a network node receiving independent inputs that are each constrained by arrival curves, but that are served as an aggregate. Existing results (for example \cite{kesidis-00-b} and \c ...

An Exact Method for Computing the Area Moments of Wavelet and Spline Curves

Michaël Unser, Thierry Blu, Mathews Jacob

We present a method for the exact computation of the moments of a region bounded by a curve represented by a scaling function or wavelet basis. Using Green's Theorem, we show that the computation of the area moments is equivalent to applying a suitable mul ...

Activation of a terminal carboxylic acid by an internal oxazole: a novel synthesis of macrocyclodepsipeptide

Jieping Zhu

A new concept for the construction of macrocyclodepsipeptides from simple and readily available starting materials has been developed. The sequence consists of (a) a three-component reaction of an aldehyde, an amino alc., and a dipeptide isocyanate and (b) ...

A Polynomial-Time Universal Security Amplifier in the Class of Block Ciphers

We demonstrate the existence of an efficient block cipher with the property that whenever it is composed with any non-perfect cipher, the resulting product is strictly more secure, against an ideal adversary, than the original cipher. We call this property ...

Enriching buyers' experiences: the SmartClient approach

Boi Faltings, Pearl Pu Faltings

In electronic commerce, a satisfying buyer experience is a key competitive element. We show new techniques for better adapting interaction with an electronic catalog system to actual buying behavior. Our model replaces the sequential separation of needs id ...
