accurate prediction of municipal solid waste’s quality and quantity is crucial for designing and programming municipal solid waste management system. but predicting the amount of generated waste is difficult task because various parameters affect it and its fluctuation is high. in this research with application of feed forward artificial neural network, an appropriate model for predicting the...
abstract biometric access control is an automatic system that intelligently provides the access of special actions to predefined individuals. it may use one or more unique features of humans, like fingerprint, iris, gesture, 2d and 3d face images. 2d face image is one of the important features with useful and reliable information for recognition of individuals and systems based on this ...
this study was an attempt to investigate the effect of subtitling on vocabulary learning among iranian intermediate students. to find the homogeneity of the groups, tofel test was administered to student in kish mehr institute in garmsar. after analyzing the data, 60 participants (female students) who scored within the range of one standard deviation above and below the mean, were selected as h...
abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
Introduction: The cost estimation of a hospital information system software refers to estimating the cost and time required to develop the hospital information system software prior to the start of the project, which will continue until the end of production and development of the system. Estimating the cost of software to produce hospital information system is one of the major concerns of proj...

Introduction: Pharmacokinetic (PK) modeling of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely applied in tumor diagnosis and treatment evaluation. Precision analysis of the estimated PK parameters is essential when they are used as a measure for therapy evaluation or treatment planning. In this study, the accuracy of PK parameters in brain DCE...
اندازه گیری رطوبت حجمی خاک و آب قابل دسترس برای گیاهان در رشته های مختلف مانند خاکشناسی، هیدرولوژی و مهندسی آب بسیار مهم است. بنابراین بررسی متعدد رطوبت خاک و میزان قابل استفاده آن برای گیاه از مهم ترین موضوعات در علم رابطه آب، خاک وگیاه است. برای تعیین رطوبت از روش های مختلفی مانند روش مستقیم (روش وزنی) و روش های غیر مستقیم مانند استفاده از دستگاه tdr و شبکه های هوش مصنوعی مانند شبکه عصبی، فاز...
the fao penman - monteith (f-p-m) method is now broadly accepted as the standard for estimating the reference evapotranspiration (et0). the method is also now used for evaluating the temperature-based [blaney-criddle (b-c) and hargreaves-samani (h-s)] and radiation-based [jensen-haise (j-h) and turc (tc)] methods. the objective was to compare the et0 estimated by the b-c, h-s, j-h, tc methods w...
In this paper, several equations were employed to estimate global solar radiation from sunshine hours for a meteorological station in Nigde, Turkey, using only the relative duration of sunshine. These equations included the original Angstrom-Prescott linear regression and modified functions (quadratic, logarithmic and exponential functions). Estimated values were compared with measured values i...
