The output updater holds the same output value on the same port, until a control signal comes from the instruction decoder to its controller to update the output with a newer value in a certain register.
In the NCS, the discrete-time state-feedback controller is event-driven, the sensor is time-driven and the sampling period is T. The zeroth-order hold device does not update the output value until the new value arrives.
In addition, when the SR-Browser discovers a correct action and a new state, the proxy requests the SR-Browser to send the state information to update the output (lines 14, 16).
If it is the case, it updates the output.
Due to its interactive nature, this program updates the output simultaneously, when any parameter is changed, allowing the user to simulate the FC process.
Damping is implemented globally by multiplying damping factors from each surface onto each resonator it is contact with, up to a maximum, prior to updating the output of the resonator.
When a Shiny application is updating, the output is "grayed out" indicating to the user that processing is taking place.
Simulating the population (1,000 individuals) and updating the output plot using a Shiny application was considerably faster than that achieved by the combined NONMEM® simulation and R processing times (NONMEM® + R method).
The iterative UFIR estimator requires that we start with initial values that are available from the batch algorithm, which typically requires matrix computations on the order of K×K dimensions, and then we iteratively update the estimator output.
The DAQ device was driven by a custom Labview program (available on request) which could monitor an accelerometer mounted to the bayonet holder and update the LED output level every 7 8 ms. In later experiments, we constructed a dedicated device based on an Arduino Uno microcontroller board (www.arduino.cc/) driven by custom firmware.
