APPLICATION OF ARTIFICIAL NEURAL NETWORK (ANN) FOR PREDICTION OF SENSIBLE AND LATENT HEAT LOSSES FROM A COW
Keywords:
Artificial neural network. heat losses . evaporative cooling. convective cooling. wet furAbstract
Artificial Neural Network (ANN) based on feed-forward backpropagation model is used to
predict sensible and latent heat losses from the wet-skin surface and fur laver of a cow. A
mathematical model is used 10 generate training data to train the neural network. The
predicted skin temperalures, latent. convective, radiative, sensible and total heat losses
due to the change in the level of wetness. air velocity. relative humidity and ambient air
temperature using ANN agree very closely with those obtained from the mathematical
model used in the analysis .
