The farmer who is not familiar with the importance of marketing and its technology will not be able to succeed in selling their product and may sell your product at a cheaper price and will be deprived of inter...

successful modeling of hydro-environmental processes widely relies on quantity and quality of accessible data and noisy data might effect on the functioning of the modeling. on the other hand in training phase of any artificial intelligence (ai) based model, each training data set is usually a limited sample of possible patterns of the process and hence, might not show the behavior of whole pop...

this paper presents a model of a catchment area in northwest of iran. the researchers have studied ajichai basin which is located in the east part of orumiyeh lake, located at the longitude of 47 52’ e to 45 32’ e and the latitude of 37 26’ n to 38 30’ n. the researchers have chosen the data from tabriz upper air station which is the only one in the area. the research data are seven instability...

the objective of this paper is to develop an artificial neural network (ann) model which can beused to predict temperature rise due to climate change in regional scale. in the present work data recorded overyears 1985-2008 have been used at training and testing steps for ann model. the multilayer perceptron(mlp) network architecture is used for this purpose. three applied optimization methods a...
