1. The question of when solutions of the Lorenz equations are periodic and when non-periodic is in fact a matter of some complexity.

2. Finding Cycles: Periodic and Nonperiodic.

3. But nonperiodic Hubbard model are different from an uniform model, there is no charge density wave state in uniform model.

4. We discuss the nonperiodic abnormal stripe noise due to the spaceborne SAR system itself, and present an area filtering method in two-dimensional frequency domain.

5. Defected Ground Structure (DGS) is a nonperiodic structure proposed in recent years,() which means machining various shapes of etching on the ground plane.

6. Furthermore, the effect of Combinatorial Nonperiodic Defected Ground Structure (CNPDGS)on the characteristic of the low-pass filter formed by the CNPDGS structure is studied.

7. These signals are instantaneous and nonperiodic, some of them have very high frequency.

8. The periodic source and the nonperiodic source e-citations to the first-order linear circuit are analysed in detail by using four factors method.

9. This paper explains a new nonperiodic Amplitude-Phase Code, which has multi-level quantized amplitude and low auto-correlation sidelobes.

10. The method can be used in the measurement of periodic and nonperiodic signal.

11. However, sounds that display a recognizable periodicity tend to be more musical than those that are nonperiodic .

12. Comparing with Fourier full-cycle filtering method, it has more advantageous in restricting nonperiodic component.

13. A symmetrical ferromagnetic bilayer film is investigated under the nonperiodic boundary condition and considering anisotropic field at two surfaces, by using the rescaling interface approach.

14. Complex implies just that, nonlinear implies recursion and higher mathematical algorithms, and dynamic implies nonconstant and nonperiodic.

15. The scientific and philosophy location of complexity concept was discussed, and a definition was given that" there are many distinguishable states that are meaningful, uncertain and nonperiodic".

16. The authors present a new real-time scheduling algorithm with fault-tolerance for nonperiodic tasks.

17. The results of the studies indicate that the time-evolution of atomic particle's occupancy of the four-level system is nonperiodic.

18. Two models of 2D photonic crystal of line defects and nonperiodic dielectric rods are established. The finite-difference-time-domain method is developed for the study of bandgap.
