  2. Spirometry - Wikipedia

    en.wikipedia.org/wiki/Spirometry

    P max is the asymptotically maximal pressure that can be developed by the respiratory muscles at any lung volume and P i is the maximum inspiratory pressure that can be developed at specific lung volumes. [26] This measurement also requires pressure transducers in addition.

    Walmart, the world's largest company by revenue since 2014 [1]. This list comprises the world's largest companies by consolidated revenue, according to the annually ranked Fortune Global 500 published by Fortune magazine, as well as other sources. [2]

  4. Maximum flow problem - Wikipedia

    en.wikipedia.org/wiki/Maximum_flow_problem

    The maximum flow problem was first formulated in 1954 by T. E. Harris and F. S. Ross as a simplified model of Soviet railway traffic flow. [1] [2] [3]In 1955, Lester R. Ford, Jr. and Delbert R. Fulkerson created the first known algorithm, the Ford–Fulkerson algorithm.

    Flux F through a surface, dS is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.

  6. Softmax function - Wikipedia

    en.wikipedia.org/wiki/Softmax_function

    In the language of tropical analysis, the softmax is a deformation or "quantization" of arg max and arg min, corresponding to using the log semiring instead of the max-plus semiring (respectively min-plus semiring), and recovering the arg max or arg min by taking the limit is called "tropicalization" or "dequantization".

  8. Choked flow - Wikipedia

    en.wikipedia.org/wiki/Choked_flow

    If the fluid is a liquid, a different type of limiting condition (also known as choked flow) occurs when the venturi effect acting on the liquid flow through the restriction causes a decrease of the liquid pressure beyond the restriction to below that of the liquid's vapor pressure at the prevailing liquid temperature.

  9. Volumetric flow rate - Wikipedia

    en.wikipedia.org/wiki/Volumetric_flow_rate

    Volumetric flow rate is defined by the limit [3] = ˙ = =, that is, the flow of volume of fluid V through a surface per unit time t.. Since this is only the time derivative of volume, a scalar quantity, the volumetric flow rate is also a scalar quantity.
