A rough guide is that if the change in measurement falls outside the margin of error, it is worth attention.

This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647-700 is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.

The map is a rough guide only, and not intended to be 100 % accurate.

The criterion is that the frequency of the least common morph is too high simply to be the result of new mutations or, as a rough guide, that it is greater than 1 percent ( though that is far higher than any normal mutation rate for a single allele ).

The following is a rough guide to equivalencies between modern Chinese words and modern Sino-Japanese on ' yomi readings.

It can cross comparatively rough terrain at high speeds, but is fuel, maintenance, and ammunition-hungry which makes it logistically demanding.

Some passages can be very rough during the winter.

So it can be more useful to think in terms of broad " movements " that have rough beginnings and endings.

As a halite crystal is growing, new atoms can very easily attach to the parts of the surface with rough atomic-scale structure and many dangling bonds.

One of these, Itō's lemma, expresses the composite of an Itō process ( or more generally a semimartingale ) dX < sub > t </ sub > with a twice-differentiable function f. In Itō's lemma, the derivative of the composite function depends not only on dX < sub > t </ sub > and the derivative of f but also on the second derivative of f. The dependence on the second derivative is a consequence of the non-zero quadratic variation of the stochastic process, which broadly speaking means that the process can move up and down in a very rough way.

Such a formula for estimating energy typically has relative error of order of 10 %, but can be used to get a rough qualitative idea and understanding of a molecule.

One often cited description that Mandelbrot published to describe geometric fractals is " a rough or fragmented geometric shape that can be split into parts, each of which is ( at least approximately ) a reduced-size copy of the whole "; this is generally helpful but limited.

Because it relies on volunteers and uses " rough consensus and running code " as its touchstone, results can be slow whenever the number of volunteers is either too small to make progress, or so large as to make consensus difficult, or when volunteers lack the necessary expertise.

This behavior can worsen when the knot is repeatedly strained and let slack, dragged over rough terrain, or repeatedly struck against hard objects such as a masts and flagpoles.

It has been proposed that children acquire these meanings with the use of processes modeled by latent semantic analysis ; that is, when they meet an unfamiliar word, children can use information in its context to correctly guess its rough area of meaning.

Mindmaps can be drawn by hand, either as " rough notes " during a lecture or meeting, for example, or as higher quality pictures when more time is available.

They would have been kept by the Scots and Picts, and used to help in providing part of their diet, namely hoofed game ( archaeological evidence likely supports this in the form of Roman pottery from around 1st Century AD found in Argyll which depicts the deerhunt using large rough hounds ( these can be viewed at the National Museum of Scotland in Edinburgh ).
