A diagram showing the relationship for flow depth (y) and total Energy (E) for a given flow (Q). 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 ...
The upper half of this diagram shows the frequency spectrum of a modern switching power supply which employs spread spectrum. The lower half is a waterfall plot showing the variation of the frequency spectrum over time during the power supply's heating up period. Spectrogram and 3 styles of waterfall plot of a whistled sequence of 3 notes vs time
This method considers the flow of water down of a series of pagoda roofs. Regions where the water will not flow identify the rainflow cycles which are seen as an interruption to the main cycle. Reduce the time history to a sequence of (tensile) peaks and (compressive) valleys. Imagine that the time history is a template for a rigid sheet ...
An example of waterfall charts. Here, there are 3 total columns called Main Column1, Middle Column, and End Value. The accumulation of successive two intermediate columns from the first total column (Main Column1) as the initial value results in the 2nd total column (Middle Column), and the rest accumulation results in the last total column (End Value) as the final value.
A Campbell diagram plot represents a system's response spectrum as a function of its oscillation regime. It is named for Wilfred Campbell, who introduced the concept. It is named for Wilfred Campbell, who introduced the concept.
Least-squares adjustment is a model for the solution of an overdetermined system of equations based on the principle of least squares of observation residuals. It is used extensively in the disciplines of surveying , geodesy , and photogrammetry —the field of geomatics , collectively.
Data flow diagram with data storage, data flows, function and interface A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system ). The DFD also provides information about the outputs and inputs of each entity and the process itself.
If a fully working design document is present (as is the intent of big design up front and the waterfall model), new team members and new teams should be able to familiarise themselves to the project by reading the documents. [19] The waterfall model provides a structured approach; the model itself progresses linearly through discrete, easily ...
