n.
A data-processing error arising when the absolute value of a computed quantity is smaller than the limits of precision of the computing device, retaining at least one significant digit.

The proposed research focuses on: i) modeling and algorithm development for sediment transport in river and coastal flows and for inland and offshore turbidity currents or debris flows, and ii) experiments and simulations of sediment transport in river and coastal flows, and sediment-laden density underflows in reservoirs and submarine canyons.
More importantly, the underflows and overflows may be caused by expanding of prediction errors during its watermark embedding process, which would cause errors in the recovered data and should be completely prevented.
In addition, the sulfur partitioning capabilities of these units were exploited to ensure that nearly all of the high density pyritic sulfur was captured in the cyclone underflows.
It also converted a froth pump into a unit capable of handling the heavy thickener underflows, a job usually assigned to piston-type pumps.
The change from implementing a control algorithm in floating-point to fixed-point math can take a great amount of time, and overflows and underflows inherent in fixed-point operations can wreak havoc with control loops.
The occurrence of underflows or hyperpycnal currents originating from the mouth of the Salinas River should be no surprise, given the long-known riverine bathometric feature existing between the river and Monterey Canyon ("Sediments sink river's flow into sea," SN: 11/17/01, p.
The remaining computational problems have to do with possible overflows or underflows.
Our (new) lower bounds let us scale the weights, via the choice of w(m), to guarantee without repeated checking that no underflows or overflows occur.
To demonstrate the impact of the NAD-RC on the smoothness of playback video quality, we compare the number of buffer underflows between NAD-RC and SRC using the buffer driven scheme.
Thickeners generate high density underflows with high yield stress, which are often pumped long distances to a final disposal area.
These underflows were detected by tethered vehicles remotely operated from ships and by seafloor instruments, says Kenneth S.
