A method is provided for maintaining a biomass disposed on a substrate in a bioreactor tank. A number of sub-phases forming a sequence of the pulses are applied to organism, the sequence including an initial pulse an a final pulse. A convolutional neural network can be employed to compute a classification function at multiple positions and take grey-level input which eliminates binarization. As such, the de-shedding blades may cut the matted portions to assist in the removal or untangling of the matted portions of fur. Other embodiments are disclosed. Each second unit of physiological data corresponds to a medical parameter being monitored by the second monitoring device.
