  2. Braking distance - Wikipedia

    en.wikipedia.org/wiki/Braking_distance

    Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.

  3. Frequency selective surface - Wikipedia

    en.wikipedia.org/wiki/Frequency_selective_surface

    The FSS sheet may be represented in terms of lumped RLC networks placed in parallel across the transmission line. The shunt admittance FSS model is exact only for an infinitesimally thin FSS, for which the tangential electric field is continuous across the FSS; for finite thickness FSS, a tee or pi network can be used as a better approximation.

  4. Optimal stopping - Wikipedia

    en.wikipedia.org/wiki/Optimal_stopping

    Optimal stopping problems can be found in areas of statistics, economics, and mathematical finance (related to the pricing of American options). A key example of an optimal stopping problem is the secretary problem.

  5. Stopping sight distance - Wikipedia

    en.wikipedia.org/wiki/Stopping_sight_distance

    Stopping sight distance is one of several types of sight distance used in road design. It is a near worst-case distance a vehicle driver needs to be able to see in order to have room to stop before colliding with something in the roadway, such as a pedestrian in a crosswalk, a stopped vehicle, or road debris .

  6. Byju's - Wikipedia

    en.wikipedia.org/wiki/Byju's

    The Future School aims to cross the bridge from passive to active learning with an interactive learning platform blended with coding and other subjects like Math, Science, English, Music and Fine arts through storytelling. Byju's will launch the Future School in the United States, United Kingdom, Australia, Brazil, Indonesia and Mexico in May. [47]

  7. Pedestrian crossing - Wikipedia

    en.wikipedia.org/wiki/Pedestrian_crossing

    Notes Informal crossings Crossings giving equal priority to pedestrian and vehicular traffic. A refuge is sometimes installed so that a pedestrian can cross in two stages; called 'unmarked crosswalk' in North America. Zebra crossing Formed of black and white stripes (resembling a Zebra). Pedestrians normally have priority over vehicular traffic.

  8. Collatz conjecture - Wikipedia

    en.wikipedia.org/wiki/Collatz_conjecture

    The smallest i such that a i < a 0 is called the stopping time of n. Similarly, the smallest k such that a k = 1 is called the total stopping time of n. [2] If one of the indexes i or k doesn't exist, we say that the stopping time or the total stopping time, respectively, is infinite. The Collatz conjecture asserts that the total stopping time ...

  9. Newton's method in optimization - Wikipedia

    en.wikipedia.org/wiki/Newton's_method_in...

    The geometric interpretation of Newton's method is that at each iteration, it amounts to the fitting of a parabola to the graph of () at the trial value , having the same slope and curvature as the graph at that point, and then proceeding to the maximum or minimum of that parabola (in higher dimensions, this may also be a saddle point), see below.
