All Implemented Interfaces:

java.lang.Cloneable

public class VonForresterA_Aff

extends Affector

This affector implements one half of a constant delay through a von Forrester equation. This affector represents the flux INTO the delayed node from the previously delayed node and is for use on both membrane and cytoplasmic nodes. Use VonForresterB_Aff for the flux out of the delayed node.

Effectively, this is a bucket brigade, or conveyor belt, where the delay is implemented as a series of nodes, each a delayed version of the previous. Using too few delay nodes will result in lowpass filtering. In general, you should look at the highest frequency/most rapid change you care about, and use as many delay nodes as necessary to preserve the features you want.

The parameter v is the velocity or rate that one delay node transfers into the next. It should be equal to the number of delay nodes divided by the maximal delay.

Formula
dNodeDelay_N/dt = vNodeDelay_N-1

Parameters

Current delayed node [NodeDelayN]	The delayed node being calculated
Previous delayed node [NodeDelayN-1]	The delayed node feeding into this delayed node
Velocity [v]	The rate of transfer into & out of this node. Should be equal to the number of delay nodes/time of delay

Usage
