nonperiodic การใช้

• Systems that show QPOs sometimes also show nonperiodic noise that appears as a continuous curve in the power spectrum.
• If a CDS is a notional principal contract, pre-default periodic and nonperiodic payments on the swap are deductible and included in ordinary income.
• This result is also valid for nonperiodic points, as long as they lie in some hyperbolic set ( stable manifold theorem for hyperbolic sets ).
• This means roughly that it is a " nonperiodic oscillator "; it produces an oscillating waveform that, unlike an ordinary electronic oscillator, never " repeats ".
• His Ph . D . advisor was Alan N . Willson Jr . and his Ph . D . dissertation is entitled " Nonperiodic forced overflow oscillations in digital filters ".
• In the 1880s, while studying the three-body problem, he found that there can be orbits that are nonperiodic, and yet not forever increasing nor approaching a fixed point.
• Although chaotic planetary motion had not been observed, experimentalists had encountered turbulence in fluid motion and nonperiodic oscillation in radio circuits without the benefit of a theory to explain what they were seeing.
• In 1977 Robert Ammann discovered a number of sets of aperiodic prototiles, i . e ., prototiles with matching rules forcing nonperiodic tilings; in particular, he rediscovered Penrose's first example.
• In this way, triggering allows the display of periodic signals such as sine waves and square waves, as well as nonperiodic signals such as single pulses, or pulses that do not recur at a fixed rate.
• The tilings obtained from an aperiodic set of tiles are often called aperiodic tilings, though strictly speaking it is the tiles themselves that are aperiodic . ( The tiling itself is said to be " nonperiodic " .)
• Lorenz went on to explore the underlying mathematics and published his conclusions in a seminal work titled " Deterministic Nonperiodic Flow ", in which he described a relatively simple system of equations that resulted in a very complicated dynamical object now known as the Lorenz attractor.
• In 1963 Lorenz published a theoretical study of this effect in a highly cited, seminal paper called " Deterministic Nonperiodic Flow " ( the calculations were performed on a Royal McBee LGP-30 computer ) . } } Following suggestions from colleagues, in later speeches and papers Lorenz used the more poetic butterfly.
• He combined practical astronomy with an interest in theory, This work was to influence Poincar?whose work on the three-body problem led to the discovery that there can be orbits which are nonperiodic, and yet not forever increasing nor approaching a fixed point, the beginning of what we now know as'chaos theory '.
