  2. Multipurpose Applied Physics Lattice Experiment - Wikipedia

    en.wikipedia.org/wiki/Multipurpose_Applied...

    An operational license for the MAPLE I reactor was granted in 1999, and the reactor went critical for the first time in early 2000. MAPLE II followed in the fall of 2003. Problems with the reactors during the testing period, most notably an unexpected positive power co-efficient of reactivity , led to the cancellation of the project in 2008 and ...

  3. Lattice Boltzmann methods - Wikipedia

    en.wikipedia.org/wiki/Lattice_Boltzmann_methods

    Schematic of D2Q9 lattice vectors for 2D Lattice Boltzmann. Unlike CFD methods that solve the conservation equations of macroscopic properties (i.e., mass, momentum, and energy) numerically, LBM models the fluid consisting of fictive particles, and such particles perform consecutive propagation and collision processes over a discrete lattice.

  4. Motion picture film scanner - Wikipedia

    en.wikipedia.org/wiki/Motion_picture_film_scanner

    Splitting a film image into three colours in a Spirit DataCine scanning machine, 2006. The front end of a motion picture film scanner is similar to a telecine.The imaging system may be either a charge-coupled device (CCD), a complementary metal–oxide–semiconductor (CMOS) or photomultipliers imaging pick up.

  5. Crystal momentum - Wikipedia

    en.wikipedia.org/wiki/Crystal_momentum

    This is a relation of inter-oscillator distances to the spatial Nyquist frequency of waves in the lattice. [1] See also Aliasing § Sampling sinusoidal functions for more on the equivalence of k-vectors. In solid-state physics, crystal momentum or quasimomentum is a momentum-like vector associated with electrons in a crystal lattice. [2]

  6. Lattice light-sheet microscopy - Wikipedia

    en.wikipedia.org/wiki/Lattice_light-sheet_microscopy

    Lattice light-sheet microscopy is a modified version of light sheet fluorescence microscopy that increases image acquisition speed while decreasing damage to cells caused by phototoxicity. This is achieved by using a structured light sheet to excite fluorescence in successive planes of a specimen, generating a time series of 3D images which can ...

  7. Relaxation (NMR) - Wikipedia

    en.wikipedia.org/wiki/Relaxation_(NMR)

    The fact that T 1 relaxation involves an interaction with the surroundings is the origin of the alternative description, spin-lattice relaxation. Note that the rates of T 1 relaxation (i.e., 1/ T 1 ) are generally strongly dependent on the NMR frequency and so vary considerably with magnetic field strength B .

  8. Optical tweezers - Wikipedia

    en.wikipedia.org/wiki/Optical_tweezers

    The main mechanism for sorting is the arrangement of the optical lattice points. As the cell flow through the optical lattice, there are forces due to the particles drag force that is competing directly with the optical gradient force (See Physics of optical tweezers) from the optical lattice point. By shifting the arrangement of the optical ...

  9. Rectangular lattice - Wikipedia

    en.wikipedia.org/wiki/Rectangular_lattice

    The rectangular lattice and rhombic lattice (or centered rectangular lattice) constitute two of the five two-dimensional Bravais lattice types. [1] The symmetry categories of these lattices are wallpaper groups pmm and cmm respectively. The conventional translation vectors of the rectangular lattices form an angle of 90° and are of unequal ...
