today, with the advanced statistical techniques and neural networks, predictive models of distribution have been rapidly developed in ecology. purpose of this research is to predict and map the distribution of tetranychus urticae koch (acari: tetranychidae) using mlp neural networks combined with genetic algorithm in surface of farm. population data of pest was obtained in 2016 by sampling in 1...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
The erosion is one of the waster factors of land sources. Understanding of erosion danger provides possibility of identifying critical regions and priority of administrative and protective plans. The aim of this research is providing of soil Endanger map by GIS, RS and multi criteria division systems in Doab basin of Lorestan province. For purpose, data of 8 important factors in soil erosion in...
We present a new efficient stereo algorithm addressing robust disparity estimation in the presence of the noises. Originality of this method is a dense disparity map estimation using the dynamic programming constrained by interest points and using Higher Order Statistics (HOS) (Cumulant) criteria for matching noisy images. Hierarchical scheme is used to ameliorate HOS-based correlation method. ...
Among the heavy metals, arsenic is known as a carcinogen material and its high concentrations in the ecosystem can be a major concern for public health and environment. The aim of this study was to evaluate the risk map of arsenic contamination and the possibility of its entering into the food chain using the fuzzy method in the central part of the Hamedan-Bahar plain. For this purpose, arsenic...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
BACKGROUND Near-infrared spectroscopy (NIRS) is a non-invasive neuroimaging technique that recently has been developed to measure the changes of cerebral blood oxygenation associated with brain activities. To date, for functional brain mapping applications, there is no standard on-line method for analysing NIRS data. METHODS In this paper, a novel on-line NIRS data analysis framework taking a...
at the highest signal levels, the masking function for the off-frequency condition seems to become more linear. while some basilar membrane data show more linear growth at high levels, others do not. aim of the present study is to assess function of masking at high levels regarding its clinical appearance. in this experiment we evaluated the hearing thresholds of three different signals (wide-b...
In this paper, in order to study a nonlinear dissipative cavity a linear master equation of the cavity in generalized to a nonlinear one at zero temperature. Then, it is shown that nonlinear coherent states are the only preferred states of the system under decoherence
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
