blood samples (291857) from 24 provinces of iran were tested for abo and rh groups. the rh complexes as well as kell, duffy, kidd, lutheran, kp and xg blood groups were tested only on a part of the material from tehran. results show a great deal of heterogeneity for abo and rh groups in various provinces of iran. the calculated gene frequencies are compared with those of other investigations in...
abstract recent interest in describing the spatial distribution patterns of weeds through using interpolation methods has increased to estimate weed seedling density from spatially refferenced data and evaluation of applicable to site-specific weed management. in this research, a multi layer perceptron neural network (mlpnn) model was developed to predict the spatial distribution of h. glaucum ...
one of the most crucial elements of each country is electricity distribution networks (edn). awareness of accidents in edn could be very important in the conservation and utilization of them. the accurate and periodic inspections can provide a good service to subscribers. the goal of this project is to fabricate a quad rotor, which can do an accurate and a periodic inspection. the design and im...
Introduction: Obesity and hypertension are community health problems. The objective of this study was to diagnose obesity and hypertension in Isfahani students by artificial neural network. Method: The present study was a diagnostic and predictive one that used the information of 460 students aged 7-18 years old in Isfahan to design a neural network with 11 input variables (age, sex, weight, he...
Resilience is defined as the system ability to keep an acceptable performance level against a sever disturbance and to return to a stable condition in a suitable time. Occurrence of inconvenient weather conditions and natural disasters, which are growing in number and severity during the last years, has always led to damages and wide outage throughout the distribution network. Therefore the ass...
Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...
Background and purpose: Chloroform is a disinfection byproducts (DBPs) that results from reactions between residual chlorine and organic compounds as precursors. The presence of these DBPs in chlorinated drinking water can pose a severe public health threat including potential carcinogenicity. In this study chloroform concentrations as an indicator of DBPs of chlorinated water was evaluated in ...
For any agency dealing with the design of the water distribution network, an economic design will be an objective. In this research, Central Force Optimization (CFO) and Differential Evolution (DE) algorithm were used to optimize Ismail Abad water Distribution network. Optimization of the network has been evaluated by developing an optimization model based on CFO and DE algorithm in MATLAB and ...
This paper presents an optimal method of frequency load shedding (UFLS) based on the rate of change of frequency of load (ROCOFL) in islanded distribution networks (DN). The proposed method minimizes the average amount of penalties paid by the independent operator of the network by utilizing the relevant cost function. The function of islanded distribution network occurs after an error in the s...
abstract forecasting electrical energy demand and consumption is one of the important decision-making tools in distributing companies for making contracts scheduling and purchasing electrical energy. this paper studies load consumption modeling in hamedan city province distribution network by applying esn neural network. weather forecasting data such as minimum day temperature, average day temp...
