In this paper the Harmonic features based on the harmonic decomposition of the Hildebrand { Prony line spectrum are introduced. A Hildebrand { Prony method of spectral analysis was applied because of its high resolution and accuracy. Comparative tests with the LP and LP { cepstral features were made with 50 speakers from the Slovene database SNABI (isolated words corpus) and 50 speakers of the ...

Echo-enabled harmonic generation free electron lasers hold great promise for the generation of fully coherent radiation in x-ray wavelengths. Here we report the first evidence of high harmonics from the echo-enabled harmonic generation technique in the realistic scenario where the laser energy modulation is comparable to the beam slice energy spread. In this experiment, coherent radiation at th...

detection & classification of power quality (pq) disturbances are the most important problems in distribution systems. in this paper, a new approach for the detection and classification of single and combined pq disturbances is proposed which utilizes fuzzy logic and particle swarm optimization (pso) algorithms. in this approach, first suitable features of the waveform of pq disturbances ar...

For stationary harmonic maps between Riemannian manifolds, we provide a necessary and sufficient condition for the uniform interior and boundary gradient estimates in terms of the total energy of maps. We also show that if analytic target manifolds do not carry any harmonic S2, then the singular sets of stationary maps are m ≤ n− 4 rectifiable. Both of these results follow from a general analys...

A total of 4 algorithms have been submitted. They consist in a set of Matlab functions and a binary file compiled under the Windows operating system. In accordance with the functional framework for rhythm description systems proposed in [2], the algorithms consist in three main processing blocks: feature list creation from audio, periodicity function computation and parsing. Low-level features ...

Electrostatics of polar solvation is typically described by harmonic free energy functionals. Polarizability contributes a negative polarization term that can make the harmonic free energy negative. The harmonic truncation fails in this regime. Simulations of polarizable ideal dipoles in water show that water's susceptibility passes through a maximum in the range of polarizabilities zeroing the...

The problem of estimating the fundamental frequency and the amplitudes and phases of corresponding harmonics is considered. Many battlefield vehicles generate coupled harmonic acoustics. These features are useful in tracking and classifying battlefield targets. As discussed in [1], harmonic line association (HLA) is a feasible approach to target identification in single or multiple target scena...

For the Schrödinger flow from R2 × R+ to the 2-sphere S2, it is not known if finite energy solutions can blow up in finite time. We study equivariant solutions whose energy is near the energy of the family of equivariant harmonic maps. We prove that such solutions remain close to the harmonic maps until the blowup time (if any), and that they blow up if and only if the length scale of the neare...

The problem of a quantum oscillator coupled to an independent-oscillator model of a heat bath is discussed. The transformation to normal coordinates is explicitly constructed using the method of Ullersma. With this transformation an alternative derivation of an exact formula for the oscillator free energy is constructed. The various contributions to the oscillator energy are calculated, with th...
