Constructor Detail

RunningAverage

public RunningAverage(int reductionFactor)

Parameters:

reductionFactor - the factor, by which the number of points count will be reduced for this ExperimentalData.

RunningAverage

public RunningAverage()

Method Detail

process

public List<Point2D> process(List<Point2D> points)

Constructs a deliberately crude representation of this heating curve by calculating a running average.

This is done using a binning algorithm, which will group the time-temperature data associated with this ExperimentalData in count/reductionFactor - 1 bins, calculate the average value for time and temperature within each bin, and collect those values in a List<Point2D>. This is useful to cancel out the effect of signal outliers, e.g. when calculating the half-rise time.

The algorithm is described in more detail in Lunev, A., & Heymer, R. (2020). Review of Scientific Instruments, 91(6), 064902.

Specified by:

process in interface Filter

Parameters:

Returns:

a List<Point2D>, representing the degraded ExperimentalData.
