Thus it simply translates inflow hydrographs at the upstream end of the conduit to the downstream end, with no delay or change in shape. The normal flow equation is used to relate flow rate to flow area (or depth). This type of routing cannot account for channel storage, backwater effects, entrance/exit losses, flow reversal or pressurized flow.
The operation shift(L) has been studied in formal language theory. For instance, if L is a context-free language , then shift ( L ) is again context-free. [ 6 ] [ 7 ] Also, if L is described by a regular expression of length n , there is a regular expression of length O ( n 3 ) describing shift ( L ).
Note the location of critical flow, subcritical flow, and supercritical flow. The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. (Note, energy and head are synonymous in Fluid Dynamics.
A bitwise AND is a binary operation that takes two equal-length binary representations and performs the logical AND operation on each pair of the corresponding bits. Thus, if both bits in the compared position are 1, the bit in the resulting binary representation is 1 (1 × 1 = 1); otherwise, the result is 0 (1 × 0 = 0 and 0 × 0 = 0).
– bitwise operation "Exclusive OR" The most economical in terms of the amount of computation and expedient for constructing the Zhegalkin polynomial manually is the Pascal method. We build a table consisting of columns and + rows, where N is the number of variables in the function. In the top row of the table we place the vector of function ...
In computer science, a mask or bitmask is data that is used for bitwise operations, particularly in a bit field.Using a mask, multiple bits in a byte, nibble, word, etc. can be set either on or off, or inverted from on to off (or vice versa) in a single bitwise operation.

The Ricci flow, Calabi flow, and Yamabe flow arise in this way (in some cases with normalizations). Curvature flows may or may not preserve volume (the Calabi flow does, while the Ricci flow does not), and if not, the flow may simply shrink or grow the manifold, rather than regularizing the metric. Thus one often normalizes the flow, for ...
