Exempel på hur man kan använda QUASIPERIODIC i en mening

• The Kolmogorov–Arnold–Moser (KAM) theorem is a result in dynamical systems about the persistence of quasiperiodic motions under small perturbations.
• A quasiperiodic tiling is a tiling of the plane that exhibits local periodicity under some transformations: every finite subset of its tiles reappears infinitely often throughout the tiling, but there is no nontrivial way of superimposing the whole tiling onto itself so that all tiles overlap perfectly.
• The waves can take the form of stripes, close-packed hexagons, or even squares or quasiperiodic patterns.
• He is known, among other things, for his work on quasiperiodic superlattices, squeezed phonons, and, most recently, for the discovery of "superfocusing", a method for creating lenses that can surpass the diffraction limit without using negative refraction materials.
• In the postbifurcation state the motion is transiently chaotic, moving chaotically along the former attractor before being attracted to a fixed point, periodic orbit, quasiperiodic orbit, another strange attractor, or diverging to infinity.
• SNAs can be distinguished from periodic, quasiperiodic and chaotic attractors using the 0-1 test for chaos.
• In 2005, she was awarded the Ruth Lyttle Satter Prize in Mathematics, "for her pioneering work on non-perturbative quasiperiodic localization".
• 1999 TWAS Prize for Physics, "for design and fabrication of periodic and quasiperiodic dielectric superlattices and realization of second harmonic generation (SHG), multiple wavelength SHG, third harmonic generation, optical stability, polariton excitation, and ultrasonic generation with high frequency".
• Together with Aloysio Janner and Pim de Wolff he was one of the founders of the higher dimensional superspace approach in crystal structure analysis for the description of quasiperiodic crystals and modulated structures.
• In orbital mechanics, a libration point orbit (LPO) is a quasiperiodic orbit around a Lagrange point.
