Dipole spectrum structure of non-resonant non-pertubative driven two-level atoms [PDF]

, 2010
We analize the dipole spectrum of a two-level atom excited by a non-resonant intense monochromatic field, under the electric dipole approximation and beyond the rotating wave approximation.

On an atomic decomposition in Banach spaces [PDF]

Sahand Communications in Mathematical Analysis, 2018
An atomic decomposition is considered in Banach space.  A method for constructing an atomic decomposition of Banach  space, starting with atomic decomposition of  subspaces  is presented. Some relations between them are established.

Harmonic mitigation potential of shunt harmonic impedances [PDF]

Electric Power Systems Research, 2003
Abstract Although complete compensation is only possible using true active filters, shunt harmonic impedances (SHI) have been shown to provide a considerable reduction of the harmonic propagation. In this paper, the mitigation potential of different SHI is investigated, together with their VA-rating. It is shown that a resistive impedance of 1 pu for

Analysis of arbitrary tooth profiles of cylindrical gears using normal polar coordinates (Application to the generation of a gear tooth profile by a given tooth profile of rack cutter and its interference problem)

Journal of Advanced Mechanical Design, Systems, and Manufacturing
Various coordinate systems have been used in tooth profile analysis for cylindrical gears. An effective approach to tooth profile expression using normal polar coordinates is proposed.

Fractional div-curl quantities and applications to nonlocal geometric equations

, 2017
We investigate a fractional notion of gradient and divergence operator. We generalize the div-curl estimate by Coifman-Lions-Meyer-Semmes to fractional div-curl quantities, obtaining, in particular, a nonlocal version of Wente's lemma.

Irreversible quantum graphs

, 2003
Irreversibility is introduced to quantum graphs by coupling the graphs to a bath of harmonic oscillators. The interaction which is linear in the harmonic oscillator amplitudes is localized at the vertices.

Coupling microstrip line bandpass filter applied to hybrid frequency synthesizers

Dianzi Jishu Yingyong, 2018
This paper designs a parallel coupled microstrip bandpass filter at the ends of the hybrid frequency synthesizer of PLL+DDS mixing in the outside of the feedback loop systems. This filter is used to suppress the frequency synthesizer′s spurs and harmonic
