Speech to speech translation can benefit from translation of emphasis. We propose to use an intonation model to retrieve and transfer events associated with emphasis in the intonation. This model decomposes the F0 contour into basic intonation atoms using the matching pursuit algorithm. We investigate the role of these components in the perception of emphasis. Some of the most prominent local c...

We extend the notion of atom definitions in first-order formulae by guards. These are conditions restricting the atom definition in a form that frequently occurs in many application areas of automated theorem proving. We give a sufficient and complete criterion for a formula to contain such a definition and provide an effective algorithm to actually retrieve the definition in an applicable form...

the b3lyp/6-31++g** density functional calculations were used to obtain minimum geometries and interaction energies between the molecular hydrogen and nanostructures of fullerenes, c20 (cage), c20 (bowl), c19si (bowl, penta), c19si (bowl, hexa). the h2 molecule is set as adsorbed in the distance of 3å at vertical position from surface above the pentagonal and hexagonal sites of nanostructures. ...

MNDO semi-empirical SCF MO calculations are used to study the pyramidal nitrogen atom inversion and configurational equilibria in the title compounds.

In this paper, we study the dynamics of a trapped atom interferometer with internal state labelling in presence interactions. We consider two situations: an atomic clock which states remain superposed, and inertial sensor configuration they are separated. From average spin evolution, deduce fringe contrast phase-shift. configuration, recover well-known identical rotation effect (ISRE) can signi...

in this paper, the structural properties of c20 and c12b8 fullerene interacting with glycine based onthree active sites of glycine and one c atom or one b atom in c12b8 were analyzed through thedensity functional theory. it was found out that the binding of glycine to c12b8 generated a complex.our results were extremely relevant in order to identify the potential applications of functionalizedc...

We present a guided atom laser. A Bose-Einstein condensate (BEC) is created in a crossed hybrid magnetic and an elongated optical trap, which acts as a matterwave guide. Atoms are extracted from the BEC by radio frequency (rf) outcoupling and then guided in the horizontal optical matterwave guide. This method allows to control the acceleration of the beam and to achieve large de Broglie wavelen...

Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this case it is shown how an analog of Hanbury-Brown Twiss photon-photon correlation interferometry can be used to discern a variety of interferenc...

Atomic switch is a nanoionic-device that controls the diffusion of metal ions/atoms and their reduction/oxidation processes in the switching operation to form/annihilate a conductive path [1-3]. Since metal atoms can provide a highly conductive channel even if their cluster size is in the nanometer scale, atomic switches may enable downscaling to smaller than the 11 nm technology node, which is...

In this paper, we present the implementation of Bloch oscillations in an atomic interferometer to increase the separation of the two interfering paths. A numerical model, in very good agreement with the experiment, is developed. The contrast of the interferometer and its sensitivity to phase fluctuations and to intensity fluctuations are also calculated. We demonstrate that the sensitivity to p...
