[ 1 ] - Hybrid ANFIS with ant colony optimization algorithm for prediction of shear wave velocity from a carbonate reservoir in Iran
Shear wave velocity (Vs) data are key information for petrophysical, geophysical and geomechanical studies. Although compressional wave velocity (Vp) measurements exist in almost all wells, shear wave velocity is not recorded for most of elderly wells due to lack of technologic tools. Furthermore, measurement of shear wave velocity is to some extent costly. This study proposes a novel methodolo...
[ 2 ] - Multi-Output Adaptive Neuro-Fuzzy Inference System for Prediction of Dissolved Metal Levels in Acid Rock Drainage: a Case Study
Pyrite oxidation, Acid Rock Drainage (ARD) generation, and associated release and transport of toxic metals are a major environmental concern for the mining industry. Estimation of the metal loading in ARD is a major task in developing an appropriate remediation strategy. In this study, an expert system, the Multi-Output Adaptive Neuro-Fuzzy Inference System (MANFIS), was used for estimation of...
[ 3 ] - Application of artificial intelligence methods for estimation of maximum surface settlement caused by EPB shield tunneling
Maximum surface settlement (MSS) is an important parameter for the design and operation of earth pressure balance (EPB) shields that should determine before operate tunneling. Artificial intelligence (AI) methods are accepted as a technology that offers an alternative way to tackle highly complex problems that can’t be modeled in mathematics. They can learn from examples and they are able...
[ 4 ] - تخمین سرعت موج برشی در یکی از مخازن هیدروکربوری جنوب غربی ایران با استفاده از چاه‌نمودارهای مختلف و یک روش جدید ترکیبی هوشمند
تعیین سرعت موج برشی توسط روش‌هایی مانند آنالیز مغزه مستلزم صرف زمان و هزینه گزافی می‌باشد و همچنین به علت نبود مغزه‌های کافی و تغییرات سنگ‌شناسی و ناهمگنی سنگ مخزن، تعیین این پارامتر توسط روش‌های معمول از دقت چندانی برخوردار نمی‌باشد. همچنین تاکنون روابط تجربی فراوانی نیز در مورد محاسبه سرعت امواج برشی ارائه شده است، اما در بیشتر موارد استفاده از این روابط در مناطق مختلف نمی‌تواند مطلوب باشد....
