In this paper, we present new dynamic features derived from the modulation spectrum of the cepstral traje ctories of the speech signal. Cepstral trajectories are projected over the basis of sines and cosines yie lding the cepstral modulation frequency resp ...

Pb2CoWO6 in its incommensurate phase (230 less than or equal to T less than or equal to 300 K) invariably exhibits orientational domains. Such a polydomain state has been investigated by means of X-ray diffraction at 283 K. Assuming the modulation to be on ...
An improved technique for chromatic dispersion measurements in single-mode fibers using phase-shift measurements is presented. The conventional experimental setup using a modulated light-emitting diode filtered by a monochromator as a light source, a fast ...
An experimental method is presented for characterization of the combined intensity and frequency modulation produced when the injection current of a laser diode is modulated. The reported technique is based on the analysis of the harmonic signals produced ...
The structure of a crystal of Sr0.61Ba0.39Nb2O6 has been solved and refined as an incommensurate structure in five-dimensional superspace. The structure is tetragonal, superspace group P4bm(pp1/2; p-p1/2), unit-cell parameters a = 12.4566 (9), c = 7.8698 ( ...
The incommensurate palmierite-like structure of beta-K5Yb(MoO4)(4), potassium ytterbium tetramolydate, has been refined in the (3 + 1)- dimensional monoclinic superspace group X2/m(0 rho 0) 00, with X = [0 0 0 0; 1/2 1/2 0 0; 0 0 1/2 1/2; 1/2 1/2 1/2 1/2] ...
The organic salt hexamethylenetetramine sebacate presents a 1D modulation with strong satellite reflections. Single-crystal X-ray intensities of main reflections and satellites up to sixth order have been measured at room temperature and used to refine thi ...
Understanding the physics of internal transport barriers (ITBs) is a crucial issue in developing ITER relevant advanced tokamak scenarios. To gain new information on ITBs, RF power modulation experiments, mainly devoted to the study of electron heat transp ...
In scalar-coupled spin systems where in-phase and antiphase coherences have different lifetimes, the envelopes of spin echoes may feature modulations that are induced by relaxation. These modulations are most pronounced when the couplings that lead to the ...
