    en.wikipedia.org/wiki/RAMP_Simulation_Software...

    The RAMP Model Processor mimics the system operating over the time period of interest - known in RAMP as a mission - by sampling failure and repair times from probability distributions (with probabilities drawn from a pseudo-random number generator) and combining with other data defined in the RAMP Model Builder to determine state transition ...

    en.wikipedia.org/wiki/Ramp_function

    The ramp function is a unary real function, whose graph is shaped like a ramp. It can be expressed by numerous definitions , for example "0 for negative inputs, output equals input for non-negative inputs".

    Wheelchair ramp, Hotel Montescot, Chartres, France Demonstration inclined plane used in education, Museo Galileo, Florence.. An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load.

    Passenger boarding stairs, sometimes referred to as boarding ramps, stair car or aircraft steps, provide a mobile means to traverse between the aircraft doors and the ground. Because larger aircraft have door sills 5 to 20 feet (1.5 to 6.1 m) high, stairs facilitate safe boarding and deplaning.

  7. Ski-jump (aviation) - Wikipedia

    en.wikipedia.org/wiki/Ski-jump_(aviation)

    A ski-jump ramp at the end of the flight deck redirects the aircraft to a slight upward angle, converting part of the aircraft's forward motion into a positive rate of climb. Since the aircraft is still traveling at an inadequate speed to generate enough lift, its climb rate will start to drop as soon as it leaves the flight deck.

    Block on a ramp and corresponding free body diagram of the block. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the ...
