The Portuguese system of heraldic differencing is unlike any other.

In some cases, the seasonal differencing may remove most or all of the seasonality effect.

Image differencing is an image processing technique used to determine changes between images.

Visual model differencing allows viewing the changes made between two different versions of a model.

(In the statistical analysis of time series, this operation is known as "first differencing.")

Again this drift can be removed by first differencing y to obtain z which does not drift.

Triple differencing subtracts the receiver difference from time 1 from that of time 2.

Visual differencing and merging of text files.

This initial system of differencing was dropped in favor of a longer-lasting simpler system.

Current differencing buffered amplifier in electronics.

Heraldic cadency;: The development of differencing of coats of arms for kinsmen and other purposes.

Differencing of general binary files goes under the rubric of delta encoding, with a widely-used example being the algorithm used in rsync.

Autocorrelation analysis helps to identify the correct phase of the fitted model while the successive differencing transforms the stochastic drift component into white noise.

Double differencing can be performed by taking the differences of the between satellite difference observed by receiver 1 with that observed by receiver 2.

In this case the non-stationarity can be removed from the data by first differencing, and the differenced variable will have a long-run mean of c and hence no drift.

Together the couple founded the 'Bonkyl' Stewart branch of the clan, and their descendants tended to utilise the 'Bonkyl' buckles as their heraldic differencing.

Nessyahu, H. and E. Tadmor (1990), Non-oscillatory central differencing for hyperbolic conservation laws, J. Comp.

In the course of the time series analysis, identification of cyclical and stochastic drift components is often attempted by alternating autocorrelation analysis and differencing of the trend.

Triple differencing can be performed by taking the difference of double differencing performed at time with that performed at time .

This procedure avoids the stability problems of central differencing while remaining free of the inaccuracies of numerical diffusion associated with the usual upstream differencing.

The encoder makes the role of differentiation; a quantizer precedes the differencing of adjacent quantized samples; the decoder is an accumulator, which if correctly initialized exactly recovers the quantized signal.

The latest edition of Boutell's Heraldry gives a fine series of examples of feudal differencing of arms as assumed by the family of Luterell and their associated and dependent folk.

A current differencing buffered amplifier (CDBA) is a multi-terminal active component with two inputs and two outputs and developed by Cevdet Acar and Serdar Özoğuz.

As these examples show, if the only concern is reconstruction of target, this is easily done, at the expense of a large patch, and the main concern for general-purpose binary differencing is reducing the patch size.

We now describe a method which could potentially be used to estimate the position of receiver 2 given the position of receiver 1 using triple differencing followed by numerical root finding, and a mathematical technique called least squares.
