Sociometry Based Multiparty Audio Recordings Segmentation

Alessandro Vinciarelli

This paper shows how Social Network Analysis, the sociological domain studying the interaction between people in specific social environments, can be used to assign roles to different speakers in multiparty recordings. The experiments presented in this wor ...

Towards using slide information to enhance speech transcription of meetings

Hervé Bourlard, Artem Peregoudov, Alessandro Vinciarelli

In this paper we investigate the possibility of improving the speech recognition performance of meeting recordings by using slides captured during the recording process. The key hypothesis exploited in this work is that both slides and speech carry correla ...

Uniform magnetic properties for an ultrahigh-density lattice of noninteracting Co nanostructures

Harald Brune, Stefano Rusponi, Nicolas Weiss

We report on the magnetic properties of two-dimensional Co nanoparticles arranged in macroscopically phase-coherent superlattices created by self-assembly on Au(788). Our particles have a density of 26 Tera/in(2) (1 Tera=10(12)), are monodomain, and have u ...

Storage density of shift-multiplexed holographic memory

Demetri Psaltis

The storage density of shift-multiplexed holographic memory is calculated and compared with experimentally achieved densities by use of photorefractive and write-once materials. We consider holographic selectivity as well as the recording material's dynami ...

Localized holographic recording in doubly doped lithium niobate

Demetri Psaltis

In:holographic data storage, pages of information are overlapped in the volume of the recording medium. Due to destructive read-out of holograms in photorefractive crystals such as LiNbO3:Fe, holograms are recorded with an exposure schedule in order-to equ ...

Diffraction efficiency of localized holograms in doubly doped LiNbo(3) crystals

Demetri Psaltis

The diffraction efficiency of M holograms superimposed in the volume of the recording medium is proportional to 1/M-2, me present a method, based on nondestructive localized holograms in a doubly doped LiNbO3 crystal, that allows us to also record M hologr ...

Localized holographic recording in doubly doped lithium niobate

Demetri Psaltis

Persistent holograms are recorded locally with red light in a LiNbO3 crystal doped with Mg and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We demonstrate the recording of 50 localized images as well as selective erasure in a ...

High-density recording in photopolymer-based holographic three-dimensional disks

Demetri Psaltis

The performance specifications of a holographic three-dimensional disk system are experimentally characterized. A surface density of 10 bits/mu m(2) is experimentally demonstrated with a 100-mu m-thick photopolymer as the recording medium. (C) 1996 Optical ...

Holographic Storage Using Shift Multiplexing

Demetri Psaltis

We demonstrate theoretically and experimentally a new multiplexing method for volume holographic storage using a single reference beam that is composed of multiple plane waves or is a spherical wave. We multiplex the holograms by shifting the recording mat ...
