کلیدواژه: Artificial Network,Decision Tree,Rainfall-Runoff Modeling,Wavelet Transform
نویسندگان: Davanlou Tajbakhsh A., NOURANI V., Molajou A.
ناشر: تحقیقات منابع آب ایران - Iran-Water Resources Research (IWRR)
Rainfall-runoff process is one of the most important and complex phenomena in the hydrological cycle and therefore different views have been presented for modeling the phenomenon. Obviously, the recognition of the behavior of the catchment can play an important role in selecting the appropriate mode... ادامه

کلیدواژه: Artificial Neural Network,Artificial Bee Colony Algorithm,Roller-Compacted Concrete,Compressive strength
نویسندگان: Ranjbar A., Barahmand N., Ghanbari A.
ناشر: - International Journal of Engineering
This study implemented the artificial bee colony (ABC) metaheuristic algorithm to optimize the Artificial Neural Network (ANN) values for improving the accuracy of model and evaluate the developed model. Compressive strength of RCC was investigated using mix design materials in three forms, namely v... ادامه
کلیدواژه: Rainfall Time Series,Disaggregation,Artificial Neural Networks,Wavelet Transform,Hybrid Model
نویسندگان: Farboudfam N., NOURANI V., AMINNEJAD B.
Due to the need to simulate rainfall time series at different time scales for engineering purposes on one hand and lack of recordings for these parameters in small scales caused by the administrative and financial problems, on the other hand, disaggregation of rainfall time series to the desired sca... ادامه
کلیدواژه: Metal Matrix Composite,Drilling,Thrust Force,Surface Roughness,Optimization
نویسندگان: Tahmasbi V., Sousanabadi Farahani A., Baghi M.H., Ghazi khansari D.
ناشر: مهندسی مکانیک مدرس - Modares Mechanical Engineering
Metal composites have received attention from various industries due to their excellent properties, such as a high strength-to-weight ratio and wear resistance. However, due to the presence of hard and abrasive particles, the challenges have always faced machining. Therefore, studying the effective ... ادامه

نویسندگان: ALIZADEH A., YAGHOUBI B., SHABANLOU S.
ناشر: علوم آب و خاک (علوم و فنون کشاورزی و منابع طبیعی) - Journal of Water and Soil Science
In this study, the discharge coefficient of sharp-crested weirs located on circular channels was modeled using the ANFIS and ANFIS-Firefly (ANFIS-FA) algorithm. Also, the Monte Carlo simulations (MCs) were used to enhance the compatibilities of the soft computing models. However, the k-fold cross va... ادامه
