  2. Ambiguity function - Wikipedia

    en.wikipedia.org/wiki/Ambiguity_function

    In pulsed radar and sonar signal processing, an ambiguity function is a two-dimensional function of propagation delay and Doppler frequency, (,).It represents the distortion of a returned pulse due to the receiver matched filter [1] (commonly, but not exclusively, used in pulse compression radar) of the return from a moving target.

  3. Doppler effect - Wikipedia

    en.wikipedia.org/wiki/Doppler_effect

    The Doppler effect (also Doppler shift) is the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave. [ 1 ] [ 2 ] [ 3 ] The Doppler effect is named after the physicist Christian Doppler , who described the phenomenon in 1842.

    Or just as prosthetic limbs can become part of the body, can handwritten notes become part of the mind? Mind-body dualism: Is the mind distinct from the body? Modularity of mind: Is the mind composed of distinct modules, each evolved to solve a specific evolutionary problem from the past? Dynamical neuroscience: Is the mind a dynamical system?

  5. Inverse problem - Wikipedia

    en.wikipedia.org/wiki/Inverse_problem

    An inverse problem in science is the process of calculating from a set of observations the causal factors that produced them: for example, calculating an image in X-ray computed tomography, source reconstruction in acoustics, or calculating the density of the Earth from measurements of its gravity field.

  6. Einstellung effect - Wikipedia

    en.wikipedia.org/wiki/Einstellung_effect

    The extinction problem was a problem that could not be solved using the previous solution B − A − 2C. In order to answer the extinction problem correctly, one had to solve the problem directly and generate a novel solution. An incorrect solution to the extinction problem indicated the presence of the Einstellung effect. The problems after ...

  7. Relativistic Doppler effect - Wikipedia

    en.wikipedia.org/wiki/Relativistic_Doppler_effect

    The relativistic Doppler effect is the change in frequency, wavelength and amplitude [1] of light, caused by the relative motion of the source and the observer (as in the classical Doppler effect, first proposed by Christian Doppler in 1842 [2]), when taking into account effects described by the special theory of relativity.

  9. Tower of London test - Wikipedia

    en.wikipedia.org/wiki/Tower_of_London_test

    The test consists of two boards with pegs and several beads with different colors. The examiner (usually a clinical psychologist or a neuropsychologist) presents the examinee with problem-solving tasks: one board shows the goal arrangement of beads, and the other board is given to the examinee with the beads in a different configuration.
