In this paper a new strategy for adaptively and autonomously constructing a multi-hidden-layer feedforward neural network (FNN) is introduced. The proposed scheme belongs to a class of structure level adaptation algorithms that adds both new hidden units and new hidden layers one at a time when it is determined to be needed. Using this strategy, a FNN may be constructed having as many hidden la...

between of effective factors in agricultural crops production, climatic conditions is an important task from the view of environmental variables. on the other hand the basic in agricultural development is having detailed knowledge of the environmental characteristics in any place and applying specific management. saffron as the world's most valuable agricultural and medicinal product is among t...

this paper intends to identify and assess ecotourism potentials of different areas in maranjab desert, kashan district. the research is an applied one, and a descriptive-analytical research. both documentary and field studies have been adopted for data collection and thus identification and prioritization of areas with the highest potential for ecotourism development within the desert district ...

in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...

water is the main option of any development, so having an accurate management of groundwater is necessary. this study has been done in damghan sedimentary plain in iran, which is located in northwest of semnan province. the main objective of this research was to estimate the rate and right site of recharge in damghan plain to prevent the aquifer from decreasing the water table. for this purpose...

In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...

We introduce a deterministic chaotic system-the Szilard map-that encapsulates the measurement, control, and erasure protocol by which Maxwellian demons extract work from a heat reservoir. Implementing the demon's control function in a dynamical embodiment, our construction symmetrizes the demon and the thermodynamic system, allowing one to explore their functionality and recover the fundamental...
