In the field of structural health monitoring (SHM), with mature development artificial intelligence, deep learning-based damage identification techniques have attracted wide attention. this paper, convolutional neural network (CNN) is used to extract feature simple supported steel beams. Firstly, transient dynamic analysis beam carried out by finite element software, and acceleration response s...

The objectives of this research were to investigate influences of energy inputs and energy forms on output levels and evaluation of CO2 emissions for hazelnut production in Guilan province of Iran. Moreover, the sensitivity analysis was done by marginal physical productivity (MPP) method for energy inputs and energy using linear regression. Initial data were collected from 120 orchar...

Background & Aim: Energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. If one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. In addition to the net income of the farmers, this issue would play a sign...
