  2. Quantum efficiency - Wikipedia

    en.wikipedia.org/wiki/Quantum_efficiency

    A graph showing variation of quantum efficiency with wavelength of a CCD chip from Wide Field and Planetary Camera 2, formerly installed on the Hubble Space Telescope.. The term quantum efficiency (QE) may apply to incident photon to converted electron (IPCE) ratio [1] of a photosensitive device, or it may refer to the TMR effect of a magnetic tunnel junction.

  3. Dixon's Q test - Wikipedia

    en.wikipedia.org/wiki/Dixon's_Q_test

    To apply a Q test for bad data, arrange the data in order of increasing values and calculate Q as defined: Q = gap range {\displaystyle Q={\frac {\text{gap}}{\text{range}}}} Where gap is the absolute difference between the outlier in question and the closest number to it.

  4. Fusion energy gain factor - Wikipedia

    en.wikipedia.org/wiki/Fusion_energy_gain_factor

    The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb was the first device able to achieve fusion energy gain factor significantly larger than 1.. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.

  5. Quantum electrodynamics - Wikipedia

    en.wikipedia.org/wiki/Quantum_electrodynamics

    To calculate the probability of any interactive process between electrons and photons, it is a matter of first noting, with Feynman diagrams, all the possible ways in which the process can be constructed from the three basic elements. Each diagram involves some calculation involving definite rules to find the associated probability amplitude.

  6. Rayleigh–Ritz method - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Ritz_method

    For example, in the case of beam deflection problems it is wise to use a deformed shape that is analytically similar to the expected solution. A quartic may fit most of the easy problems of simply linked beams even if the order of the deformed solution may be lower.

  7. Delta potential - Wikipedia

    en.wikipedia.org/wiki/Delta_potential

    Source: [1] The potential splits the space in two parts (x < 0 and x > 0).In each of these parts the potential is zero, and the Schrödinger equation reduces to =; this is a linear differential equation with constant coefficients, whose solutions are linear combinations of e ikx and e −ikx, where the wave number k is related to the energy by =.

    A Temple University student has been arrested and charged with impersonating an ICE officer after showing up at a residence hall and attempting to enter. Two "suspicious" males identified ...

  9. Signal-to-quantization-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-quantization...

    Signal-to-quantization-noise ratio (SQNR or SN q R) is widely used quality measure in analysing digitizing schemes such as pulse-code modulation (PCM).
