... It can only transmit a succession of brief explosive waves, and the message can only be varied by changes in the frequency and in the total number of these waves. … But this limitation is really a small matter, for in the body the nervous units do not act in isolation as they do in our experiments. ...

Phasic receptors can typically exhibit peripheral adaptation quickly (ex, thermoreceptors) Tonic receptors are usually "on," constantly providing information about the intensity of a stimulus ...

... The process of cooling chicken carcasses by immersing them in mixture of cold water and ice (chillers) is complex. It is very difficult to represent it by a transport phenomenon model. In this work, artificial neural networks were used with an intermediary layer in the description and modeling of th ...
