2Quasi-periodic oscillations — In high energy (X ray) astronomy, quasi periodic oscillations (QPOs) refer to the way the X ray light from an astronomical object flickers about certain frequencies. In these situations, the X rays are emitted near the inner edge of an accretion… …

5Quasi-biennial oscillation — The QBO (quasi biennial oscillation) is a quasi periodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 28 to 29 months. The alternating wind regimes develop at the… …
6Quasi-phase-matching — is a technique in nonlinear optics which allows a positive net flow of energy from the pump frequency to the signal and idler frequencies by creating a periodic structure in the nonlinear medium. Momentum is conserved, as is necessary for phase… …

8Periodic poling — is formation of layers with alternate orientation in a birefringent material. The domains are regularly spaced, with period in a multiple of the desired wavelength of operation. The structure is desired to achieve quasi phase matching (QPM) in… …

10Quasi-polynomial — In mathematics, a quasi polynomial (pseudo polynomial) is a generalization of polynomials. While the coefficients of a polynomial come from a ring, the coefficients of quasi polynomials are instead periodic functions with integral period. Quasi… …
