Detection thresholds were measured for a sinusoidal modulation applied to the modulation depth of a sinusoidally amplitude-modulated (SAM) white noise carrier as a function of the frequency of the modulation applied to the modulation depth (referred to as f'm). The SAM noise acted therefore as a "carrier" stimulus of frequency fm, and sinusoidal modulation of the SAM-noise modulation depth gene...

The aim of this work is to generalize to the case of weighted L 2 spaces some results about L 2 approximation by analytic and rational functions which are useful to perform the identiication of unknown transfer functions of stable (linear causal timeeinvariant) systems from incomplete frequency data. Approximation H 2 ponddrre de fonctions de transfert RRsumm : L'objet de ce rapport est de ggnn...

We obtain a formula for the essential spectral radius ρess of transfer-type operators associated with families of C1+δ diffeomorphisms of the line and Zygmund, or Hölder, weights acting on Banach spaces of Zygmund (respectively Hölder) functions. In the uniformly contracting case the essential spectral radius is strictly smaller than the spectral radius when the weights are positive.

The set of Head Related Transfer Functions (HRTF) enables the generation of spatial sound [1]. Two FIR filters with 512 coefficients are required for any spatial position. This paper suggests a method for the description of HRTFs which reduces the total number of necessary coefficients for the factor 4.5 – 14 and enables the construction of new filters for nonmeasured positions. The method expl...

where A is the infinitesimal generator of the C0-semigroup T (t) on the state space X, B is a bounded linear operator from input space U to X, C is a bounded linear operator from X to the output space Y , and D is a bounded operator from U to Y . The spaces X, U and Y are assumed to be Banach spaces. More detail on the system (1) can be found in Curtain and Zwart [1]. For the system (1) we intr...

Microsomal triglyceride transfer protein (MTP) was first identified as a major cellular protein capable of transferring neutral lipids between membrane vesicles. Its role as an essential chaperone for the biosynthesis of apolipoprotein B (apoB)-containing triglyceride-rich lipoproteins was established after the realization that abetalipoproteinemia patients carry mutations in the MTTP gene resu...

Transfer functions are an essential part of volume visualization. In multimodal visualization at least two values exist at every sample point. Additionally, other parameters, such as gradient magnitude, are often retrieved for each sample point. To find a good transfer function for this high number of parameters is challenging because of the complexity of this task. In this paper we present a g...

Injective one-way trapdoor functions are one of the most fundamental cryptographic primitives. In this work we give a novel construction of injective trapdoor functions based on oblivious transfer for long strings. Our main result is to show that any 2-message statistically sender-private semihonest oblivious transfer (OT) for strings longer than the sender randomness implies the existence of i...

My talk will be based on paper " Synthesis of two-dimensional loss-less m-ports with prescribed scattering matrix " by A. Kummert.

Transfer functions have a crucial role in the understanding and visualization of 3D data in the spatial domain. While exhaustive research has scrutinized the possible uses of one or multi-dimensional transfer functions in the visualization of the data in the spatial domain, to our knowledge no attempt has been done in the exploration of the use of transfer functions in the frequency domain. In ...
