WebJul 11, 2011 · An important thing to keep in mind when modeling in Simulink is that blocks run according to their sample time (see this blog post for information how you can look at your block's sample time). So if you are using a zero-order hold block, it will only hold the input for one sample period - you need to sample the sample time of the zero-order hold … WebOct 24, 2013 · Initial Time Point Testing and Use of NOE for Troubleshooting. An important consideration for hold time studies is confi rmation of the amount of endotoxin initially spiked. When the initial time point is assayed directly after NoE spiking, consideration must be taken as to whether the sample matrix has an immediate eff ect on endotoxin recovery.
