  2. Scale factor (computer science) - Wikipedia

    en.wikipedia.org/wiki/Scale_factor_(computer...

    Being integers between 0 and 255, these all can be represented precisely with 8 bits. Scaling these by 1 ⁄ 16 is the same as dividing by 16, which is the same as shifting the bits 4 places to the right. In this case, scaling is done by inserting a binary point between the first 4 bits and last 4 bits of each number.

  3. Ferroelectric RAM - Wikipedia

    The lower limit to this scaling process is an important point of comparison. In general, the technology that scales to the smallest cell size will end up being the least expensive per bit. In terms of construction, FeRAM and DRAM are similar, and can in general be built on similar lines at similar sizes.

  4. Timeline of quantum computing and communication - Wikipedia

    A large number of electrons are quantum coupled. [102] Spin–orbit interaction of electrons are measured. [103] Atoms are quantum manipulated in laser light. [104] Light pulses are used to control electron spins. [105] Quantum effects are demonstrated across tens of nanometers. [106] Light pulses are used to accelerate quantum computing ...

  5. Functional magnetic resonance imaging - Wikipedia

    Linear addition means the only operation allowed on the individual responses before they are combined (added together) is a separate scaling of each. Since scaling is just multiplication by a constant number, this means an event that evokes, say, twice the neural response as another, can be modeled as the first event presented twice simultaneously.

  6. Tokamak - Wikipedia

    en.wikipedia.org/wiki/Tokamak

    A second device, similar in concept, is used to separately accelerate electrons to the same energy. The much lighter mass of the electrons makes this device much smaller than its ion counterpart. The two beams then intersect, where the ions and electrons recombine into neutral atoms, allowing them to travel through the magnetic fields.

  7. Nuclear fusion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fusion

    The 15 Mt yield was 150% greater than the predicted 6 Mt and caused unexpected exposure to fallout. To evaluate the usefulness of these reactions, in addition to the reactants, the products, and the energy released, one needs to know something about the nuclear cross section. Any given fusion device has a maximum plasma pressure it can sustain ...

  8. Nuclear reactor - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor

    A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction.They are used for commercial electricity, marine propulsion, weapons production and research.

  9. Diffraction - Wikipedia

    en.wikipedia.org/wiki/Diffraction

    Diffraction of electrons and neutrons is one of the powerful arguments in favor of quantum mechanics. The wavelength associated with a non-relativistic particle is the de Broglie wavelength λ = h p , {\displaystyle \lambda ={\frac {h}{p}}\,,} where h {\displaystyle h} is the Planck constant and p {\displaystyle p} is the momentum of the ...
