  2. Coherence (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Coherence_(signal_processing)

    In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system .

  3. Coherence (physics) - Wikipedia

    en.wikipedia.org/wiki/Coherence_(physics)

    Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by , at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with itself at a different time.

  4. Modal analysis - Wikipedia

    en.wikipedia.org/wiki/Modal_analysis

    In structural engineering, modal analysis uses the overall mass and stiffness of a structure to find the various periods at which it will naturally resonate.These periods of vibration are very important to note in earthquake engineering, as it is imperative that a building's natural frequency does not match the frequency of expected earthquakes in the region in which the building is to be ...

  5. Modeling and simulation - Wikipedia

    en.wikipedia.org/wiki/Modeling_and_simulation

    Modeling and simulation (M&S) is the use of models (e.g., physical, mathematical, behavioral, or logical representation of a system, entity, phenomenon, or process) as a basis for simulations to develop data utilized for managerial or technical decision making.

  6. Boids - Wikipedia

    en.wikipedia.org/wiki/Boids

    As with most artificial life simulations, Boids is an example of emergent behavior; that is, the complexity of Boids arises from the interaction of individual agents (the boids, in this case) adhering to a set of simple rules.

  7. Higher order coherence - Wikipedia

    en.wikipedia.org/wiki/Higher_order_coherence

    The second order coherence for thermal, stellar and coherent light as a function of time delay. τ 0 {\displaystyle \tau _{0}} is the coherence length of the light beam. Similar to the case of Young's double slit experiment, the classical and the quantum description lead to the same result, but that does not mean that two descriptions are ...

  8. Lagrangian coherent structure - Wikipedia

    en.wikipedia.org/wiki/Lagrangian_coherent_structure

    Lagrangian coherent structures ... Examples of attracting, repelling and shearing LCSs are in a direct numerical simulation of 2D turbulence are shown in Fig.2a.

  9. Coherence time (communications systems) - Wikipedia

    en.wikipedia.org/wiki/Coherence_time...

    Coherence time is actually a statistical measure of the time duration over which the channel impulse response is essentially invariant, and quantifies the similarity of the channel response at different times. In other words, coherence time is the time duration over which two received signals have a strong potential for amplitude correlation.
