Modeling of water flow in carbon nanotubes is still a challenge for the classic models of fluid dynamics. In this investigation, an adaptive-network-based fuzzy inference system (ANFIS) is presented to solve this problem. The proposed ANFIS approach can construct an input-output mapping based on both human knowledge in the form of fuzzy if-then rules and stipulated input-output data pairs. Good...

This paper presents a comprehensive study of ANFIS+ARIMA+IT2FLS models for forecasting the weather of Raipur, Chhattisgarh, India. For developing the models, ten year data (2000-2009) comprising daily average temperature (dry-wet), air pressure, and wind-speed etc. have been used. Adaptive Network Based Fuzzy Inference System (ANFIS) and Auto Regressive Moving Average (ARIMA) models based on In...

This paper presents a hybrid adaptive network based fuzzy inference system (ANFIS), computer simulation and time series algorithm to estimate and predict electricity consumption estimation. The difficulty with electricity consumption estimation modeling approach such as time series is the reason for proposing the hybrid approach of this study. The algorithm is ideal for uncertain, ambiguous and...

تقاضای چشمگیر فزاینده برای مصرف آب ناشی از رشد جمعیت از یک سو، و منابع آب محدود از سویی دیگر، کمبود آب را به مسئله ای حیاتی در کشورمان تبدیل می نماید. این امر، به نوبه خود، اثری مخرب بر روی رودخانه ها و جریان های ورودی به مخازن سدها دارد. بنا بر این، پیش بینی جریان رودخانه برای مدیریت کیفیت آب، تولید برق آبی، سیستم های آبیاری و مدیریت بهره برداری از مخازن سدها ضروری است. در سال های اخیر، به است...

This study investigates the ability of a new hybrid neuro-fuzzy model by combining (ANFIS) approach with marine predators’ algorithm (MPA) in predicting short-term (from 1 h ahead to day ahead) significant wave heights. Data from two stations, Cairns and Palm Beach buoy, were used assessing considered methods. The ANFIS-MPA was compared other methods, ANFIS genetic (ANFIS-GA) particle swarm opt...

مقدار دبی یا رواناب خروجی از یک حوضة آبخیز از اهمیت زیادی برخوردار است؛ زیرا کمبود آن ممکن است موجب خسارات مالی و مازاد آن به صورت سیلاب ممکن است موجب خسارات جانی و مالی شود. در این پژوهش با استفاده از شبکة عصبی مصنوعی پرسپترون چندلایه (mlp) و مدل فازی عصبی تطبیقی (anfis) و روش رگرسیون چندمتغیره، فرایند بارش- رواناب به صورت روزانه در حوضة آبخیز خرم آباد شبیه سازی شد. برای ورودی ها از ترکیب های ...

The aim of this paper is to propose a procedure for model selection in Adaptive Neuro-Fuzzy Inference System (ANFIS) for time series forecasting. In this paper, we focus on the model selection based on statistical inference of R incremental. The selecting model is conducted by evaluating the inputs, number of membership functions and rules in architecture of ANFIS until the contribution of R2 i...

This paper presents an application of adaptive neuro-fuzzy (ANFIS) control for switched reluctance motor (SRM) speed. The ANFIS has the advantages of expert knowledge of the fuzzy inference system and the learning capability of neural networks. An adaptive neuro-fuzzy controller of the motor speed is then designed and simulated. Digital simulation results show that the designed ANFIS speed cont...

In this paper we apply an Adaptive Network-Based Fuzzy Inference System (ANFIS) with one input, the dependent variable with one lag, for the forecasting of four macroeconomic variables of US economy, the Gross Domestic Product, the inflation rate, six monthly treasury bills interest rates and unemployment rate. We compare the forecasting performance of ANFIS with those of the widely used linear...

314 Abstract— Neuro-Fuzzy systems are hybrid intelligent systems which combine features of both paradigmsfuzzy logic and artificial neural networks. Adaptive Neuro Fuzzy Inference System (ANFIS) is one of such architecture which is widely used as solution for various real world problems. This paper describes development of an ANFIS model for FPGA implementation. Model can be realized with hardw...
