Due to the heterogeneous distribution of precipitation, predicting its occurrence is one of the primary and basic solutions to prevent possible disasters and damages caused by them. Considering the high amount of precipitation in Sardasht County, the people of this city turning to agriculture in recent years and not using classification models in the studied station, it is necessary to predict ...
Meteorological station records often consist only of precipitation and air temperature data. There is therefore a need for appropriate methods to estimate solar radiation data to enable complete data set creation, by combining observed and estimated data. It is important to know the quality and characteristics of the estimates made in order to understand what impacts the data may have on the us...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
Walnut trees, as well their fruits, represent an important sector of the agricultural industry and cultivation significantly contributes to global economy. Irrigation is a key factor in walnut most problem related accurately estimating need for irrigation water. water use was estimated this study through artificial intelligence methods Artificial Neural Networks (ANNs) Adaptive Neuro-Fuzzy Infe...
abstract the most important part of the design and operation of the supplier systems of agricultural water requirement is the estimating of plant water requirement. in this study by using the lars-wg5 model, downscaled the data of hadcm3 model according a1b, a2 and b1 scenarios that confirmed by ipcc, and was simulated monthly amounts of precipitation, minimum temperature, maximum temperature a...
nowadays enhancing critical thinking in learners is considered one of the foreign language teachers’ tasks due to its high position in foreign language classrooms. when it comes to selecting materials for language classrooms, there are obviously some criteria that teachers should apply. the present study aimed at a critical thinking based analysis of ten picture story books and ten folktales th...
tourism is an element depends on climate so that suitable climate and weather forecast in the destination is an attractive factor for tourists. in this research we used 9 synoptic stations data and tci index of lorestan province for comfort assessment of the province .this index use 7 climatic factors includes: rainfall, temperature, mean and minimum relative humidity, maximum temperature, dail...
The ability to accurately predict daily solar radiation reaching the earth’s surface is essential in applications such as power generation. Given their ease of use, many empirical models have been proposed based on different dependent variables cloud cover, temperature range, etc. In this study we evaluate 23 these for prediction northern coastal zone Iberian Peninsula. Daily measurements durin...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
