	Stream function - Wikipedia, the free encyclopedia
		The usefulness of the stream function lies in the fact that the velocity components in the x- and y- directions at a given point are given by the partial derivatives of the stream function at that point.
		A stream function may be defined for any flow of dimensions greater than two, however the two dimensional case is generally the easiest to visualize and derive.
		Taken together with the velocity potential, the stream function may be used to derive a complex potential for a fluid flow.

	ANSI and GNU Common Lisp Document: Streams
		The action of closing a stream marks the end of its use as a source or sink of data, permitting the implementation to reclaim its internal data structures, and to free any external resources which might have been locked by the stream when it was opened.
		A concatenated stream is an input stream which is a composite stream of zero or more other input streams, such that the sequence of data which can be read from the concatenated stream is the same as the concatenation of the sequences of data which could be read from each of the constituent streams.
		A stream that is an alias for another stream, which is the value of a dynamic variable whose name is the synonym stream symbol of the synonym stream.

	Stream Function Wave Theory (Site not responding. Last check: 2007-10-09)
		The velocities and total accelerations under the forward half of the stream function wave (it is moving from left to right) can be examined by clicking the mouse at any location within the water.
		The order of the Stream function wave is a measure of how nonlinear the wave is. In deep water, the order can be low, 3 to 5 say, while, in very shallow water, the order can be as great as 30.
		This is an attempt by the Stream Function theory to develop a periodic wave train, not a new wave discovery (Dalrymple and Solano, J. Waterway, Port, Coastal and Ocean Eng, 1986).

		Such a function is called the stream function because its isolines are streamlines (that is lines such that at any given time they are tangent to the velocity vector).
		Stream function and velocity potential are both harmonic functions of space and are related by the following equations
		It is not difficult to demonstrate that by using the Cauchy-Riemann conditions, lines along which the stream function is constant (streamlines) and lines along which the velocity potential is constant (isopotential lines) always intersect at right angles.

	The STREAM_IO signature
		= 0 corresponds to the stream being at end-of-stream.
		Also note that creating an output stream this way means that the stream could be unaware that the writer has been closed until the stream actually attempts to write to it.
		This is intended as a convenience, with the inactive stream providing a handle to the underlying file, but it also provides an opportunity to close a reader or writer being actively used by another stream.

		It is an error to attempt to attach a stream to more than one mixer, or to attempt to generate sample data from a stream when it is attached to a mixer.
		For as long as the stream is attached, the mixer has a reference to it; if you call al_deref_audio_stream(), the stream will destroy itself when it ends.
		A mixer would then be any stream capable of incorporating data from another stream and adjusting its volume, frequency and channel distribution (panning/surround/3D) as well as keeping track of whether the stream is paused or not.

		As a minimum requirement, it should be the case that opening an output stream to a file in a given element type and later opening an input stream to the same file in the same element type should work compatibly.
		The act of closing a file stream ends the association between the stream and its associated file; the transaction with the file system is terminated, and input/output may no longer be performed on the stream.
		It is intended that standard input functions such as read and read-char, when used with this stream, cause echoing of the input into the output side of the stream.

	Abstract (Site not responding. Last check: 2007-10-09)
		The stream function is constant along a streamline, and the difference in its value for two streamlines represents the total flow between these streamlines.
		In the context of the analytic element method (AEM), a technique had been developed which allows the stream function to be used in models which include areal recharge or leakage.
		By treating these solutions to Poisson's equation separately, the stream function can be utilized in a manner similar to that for flow without areal recharge or leakage.

		The function setne is used to set all the flow and state conditions for the exit streams.
		Stream 2 would get 20% of the flow, as a vapor at 400 Tdeg, stream 3 would get 30% as vapor at 300 Tdeg, and stream 4 would get the remaining 50% as liquid at 200 Tdeg.

		This function causes all open streams of the process to be closed and the connection to corresponding files to be broken.
		When writing code which uses streams and which can be used in different contexts it is important to query the orientation of the stream before using it (unless the rules of the library interface demand a specific orientation).
		One of the arguments you pass to this function is a pointer to a handler function that produces the actual output; see section Defining the Output Handler, for information on how to write this function.
