  2. E/A ratio - Wikipedia

    en.wikipedia.org/wiki/E/A_ratio

    The E peak arises due to early diastolic filling. Most filling (70-85%) of the ventricle occurs during this phase. The A peak arises due to atrial contraction, forcing approximately 15-20% of stroke volume into the ventricle. The deceleration time is the time taken from the maximum E point to baseline.

  3. Deceleration parameter - Wikipedia

    en.wikipedia.org/wiki/Deceleration_parameter

    The deceleration parameter in cosmology is a dimensionless measure of the cosmic acceleration of the expansion of space in a Friedmann–Lemaître–Robertson–Walker universe. It is defined by: q = d e f − a ¨ a a ˙ 2 {\displaystyle q\ {\stackrel {\mathrm {def} }{=}}\ -{\frac {{\ddot {a}}a}{{\dot {a}}^{2}}}} where a {\displaystyle a} is ...

  4. Assured clear distance ahead - Wikipedia

    en.wikipedia.org/wiki/Assured_Clear_Distance_Ahead

    The dry rule does allow one to travel faster in dry weather, but expect emergency deceleration to be a bit uncomfortable. If one desires to remember only one rule, use the wet one. However, because the difference between wet and dry is half-a-second at 30 MPH and one second at 60 MPH, and because dividing by two is easier than three, we can use ...

  5. Jerk (physics) - Wikipedia

    en.wikipedia.org/wiki/Jerk_(physics)

    Jerk does not preclude the Geneva drive from being used in applications such as movie projectors and cams. In movie projectors, the film advances frame-by-frame, but the projector operation has low noise and is highly reliable because of the low film load (only a small section of film weighing a few grams is driven), the moderate speed (2.4 m/s ...

  6. Thrust reversal - Wikipedia

    en.wikipedia.org/wiki/Thrust_reversal

    The early deceleration provided by reverse thrust can reduce landing roll by a quarter or more. [5] Regulations dictate, however, that an aircraft must be able to land on a runway without the use of thrust reversal in order to be certified to land there as part of scheduled airline service.

  7. Tidal acceleration - Wikipedia

    en.wikipedia.org/wiki/Tidal_acceleration

    The similar process of tidal deceleration occurs for satellites that have an orbital period that is shorter than the primary's rotational period, or that orbit in a retrograde direction. These satellites will have a higher and higher orbital velocity and a shorter and shorter orbital period, until a final collision with the primary.

  9. Automated emergency braking system - Wikipedia

    en.wikipedia.org/wiki/Automated_emergency...

    AEB differs from forward collision warning: FCW alerts the driver with a warning but does not by itself brake the vehicle. [4] According to Euro NCAP, AEB has three characteristics: [5] Autonomous: the system acts independently of the driver to avoid or mitigate the accident. Emergency: the system will intervene only in a critical situation.
