  2. Loschmidt's paradox - Wikipedia

    en.wikipedia.org/wiki/Loschmidt's_paradox

    A more recent proposal concentrates on the step of the paradox in which velocities are reversed. At that moment the gas becomes an open system, and in order to reverse the velocities, position and velocity measurements have to be made. [7] Without this, no reversal is possible. These measurements are themselves either irreversible, or reversible.

  3. Algorithms for Recovery and Isolation Exploiting Semantics

    en.wikipedia.org/wiki/Algorithms_for_Recovery...

    The Previous Sequence Number is a reference to the previous log record that was created for this transaction. In the case of an aborted transaction, it's possible to traverse the log file in reverse order using the Previous Sequence Numbers, undoing all actions taken within the specific transaction.

  4. Response bias - Wikipedia

    en.wikipedia.org/wiki/Response_bias

    A survey using a Likert style response set. This is one example of a type of survey that can be highly vulnerable to the effects of response bias. Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions.

  5. Vector projection - Wikipedia

    en.wikipedia.org/wiki/Vector_projection

    The rejection of a vector from a plane is its orthogonal projection on a straight line which is orthogonal to that plane. Both are vectors. The first is parallel to the plane, the second is orthogonal. For a given vector and plane, the sum of projection and rejection is equal to the original vector.

  6. Rankine cycle - Wikipedia

    en.wikipedia.org/wiki/Rankine_cycle

    Constant pressure heat rejection in condenser The wet vapour then enters a condenser , where it is condensed at a constant pressure to become a saturated liquid . In an ideal Rankine cycle the pump and turbine would be isentropic: i.e., the pump and turbine would generate no entropy and would hence maximize the net work output.

  7. Rejection sampling - Wikipedia

    en.wikipedia.org/wiki/Rejection_sampling

    An extension of rejection sampling that can be used to overcome this difficulty and efficiently sample from a wide variety of distributions (provided that they have log-concave density functions, which is in fact the case for most of the common distributions—even those whose density functions are not concave themselves) is known as adaptive ...

  8. Reversible computing - Wikipedia

    en.wikipedia.org/wiki/Reversible_computing

    As was first argued by Rolf Landauer while working at IBM, [7] in order for a computational process to be physically reversible, it must also be logically reversible. Landauer's principle is the observation that the oblivious erasure of n bits of known information must always incur a cost of nkT ln(2) in thermodynamic entropy .

  9. Aversive racism - Wikipedia

    These pairs will also be tested in reverse order (one key for a white person or something good, another for a black person or something bad). The greater the disparity in reaction times and accuracy between the different pair groups, the greater implicit racism is measured in that individual. [11]
