regression (0.998742). It should also be observed that reliability prediction by TTF time series equally gave a considerably high value for the coefficient of determination of the linear regression line between the predicted values and the actual values (0.9824). Yet ANN model gave a better value. The closeness in the results from the two methods is not unconnected with the size of the data used for the work. Artificial Neural Network models are designed to handle stochastic and complex data analysis problems far beyond the size of example data used in this presentation. When the problem involves few data sets, statistical and probabilistic analysis tools can attempt to rival solutions offered by Artificial intelligence techniques. However, the ANN approach presented in this report still exhibited superior prediction capability over the TTF time series non- parametric analytic approach. This comparison can be done for large amount of data and other artificial intelligence techniques incorporated to fully elicit optimal reliability prediction methodology for deteriorating systems.

An Artificial Neural Network (ANN) Model for Predicting Water Absorption of Nanoclay Epoxy Composites

An Artificial Neural Network (ANN) Model for Predicting Water Absorption of Nanoclay Epoxy Composites

Glass fiber reinforced epoxy (GFRE) composite materials are prone to suffer from water absorption due to their heterogeneous structure. The main proc- ess governing water absorption is diffusion of water molecules through the epoxy matrix. However, hydrolytic degradation may also take place during components service life specially due high temperatures. In order to mitigate the effects of the water diffusive processes in the deterioration of in-service behavior of epoxy matrix composites, the use of chemically modified nano- clays as an additive has been proposed and studied in previous works [1]. In this work, an Artificial Neural Network (ANN) model was developed for bet- ter understanding and predicting the influence of modified and unmodified bentonite addition on the water absorption behavior of epoxy-anhydride sys- tems. An excellent correlation between model and experimental data was found. The ANN model allowed the identification of critical points like the precise temperature at which a particular system’s water uptake goes beyond a predefined threshold, or which system will resist an immersion longer than a particular time.

Estimation of biodiesel properties from chemical composition – an artificial neural network (ANN) approach

Estimation of biodiesel properties from chemical composition – an artificial neural network (ANN) approach

The kinematic viscosity prediction model was developed for biodiesel using an ANN which represents a mathematical relationship between input and output parameters of a system as such a black box model. The selection of input parameters which contribute to the output is therefore a crucial task. It is also desirable to minimize the number of input parameters for an ANN system in order to reduce the computational time. In general, the best input parameters are being selected based on an understanding of the physics of a problem. Published literature suggested that the kinematic viscosity of biodiesel is a function of chemical composition- the fatty acid profile of methyl ester and impurities. In the present study, 27 variables are used as input parameters in developing the ANN for viscosity prediction. These parameters include: mass percentage of 18 fatty acid methyl ester that is commonly found in the biodiesel and 9 parameters listed in Table 2. Among 352 data sets that have been collected from literature, 327 sets are used in the ANN model training process whereas other 25 data sets are randomly selected for simulation.

Predicting heat stressed EEG spectra by self organising feature map and learning vector quantizers——SOFM and LVQ based stress prediction

Predicting heat stressed EEG spectra by self organising feature map and learning vector quantizers——SOFM and LVQ based stress prediction

In the last decade, several works introduced the use of artificial neural network (ANN) as a tool for automated sleep scoring. Most of the system used spectral in- formation of the signal using Fourier transformation [2]. Computerized EEG and other electrophysiological parameters monitoring reduces the problem of huge data handling. Computerization has led to more sophisticated use of EEG, even in effective disorders, where percep- tual processes are significantly distorted [3-5]. Fourier transformation, as a conventional method, has been widely used for the standard quantitative analysis of the spectral decomposition and the clinical application of EEG signals [6]. The ANN programs were developed for the analysis of most of the works that rely on spectral analysis and power spectrum method to evaluate elec- trographic data. In an attempt to classify sleep-wake stages determined, power of FFT or power spectrum band were used for better performance of the system [3,7]. The numerical values of the power of different frequency bands were used as inputs to ANN. As multi- layer perceptron neural network (MLPNN) undergoes some limitations, the performance of SOFM has also been tested to solve the problem at hand. In the present study, an effort has been made to exploit the inherent qualities of SOFM. The results obtained from computer simulations have been found to be very encouraging.

A Survey on Deep Learning Based IoT Approach for Precision Crop Suggestion

In Maharashtra state 27 districts are chosen and in that, publicly available records were taken, these records include parameters like minimum temperature, average temperature, maximum temperature, area, and production. For this dataset Multilayer Perceptron, Neural Network is applied for processing with the help of WEKA tool. But this work suggests that in the Artificial Neural Network based model the prediction capabilities can be improved by considering additional parameters [7]. Amir Haghverdia, Robert A. Washington-Allenb, Brian G. Leibc predicted the cotton lint yield using remote sensing technology. The satellite remote sensing technology is primarily used for assessment and monitoring of the agricultural land in order to determine the area, amount and type of crop production. Deep Learning can be applied and used for this type of problems. In this Artificial Neural Network (ANN) approach is used to generate the models related to individual Crop Indices (CI) and CI phenology to map and predict the yield of cotton lint in two growing seasons.

Radio location of partial discharge sources : a support vector regression approach

Radio location of partial discharge sources : a support vector regression approach

Abstract: Partial discharge (PD) can provide a useful forewarning of asset failure in electricity substations. A significant proportion of assets are susceptible to PD due to incipient weakness in their dielectrics. This paper examines a low cost approach for uninterrupted monitoring of PD using a network of inexpensive radio sensors to sample the spatial patterns of PD received signal strength. Machine learning techniques are proposed for localisation of PD sources. Specifically, two models based on Support Vector Machines (SVMs) are developed: Support Vector Regression (SVR) and Least-Squares Support Vector Regression (LSSVR). These models construct an explicit regression surface in a high dimensional feature space for function estimation. Their performance is compared to that of artificial neural network (ANN) models. The results show that both SVR and LSSVR methods are superior to ANNs in accuracy. LSSVR approach is particularly recommended as practical alternative for PD source localisation due to it low complexity.

ANN Based Modeling for Coagulant Dosage in Drinking Water Treatment Plant

portable water demand, which requires exploration of raw water sources, developing treatment systems. The main function of water treatment plants is to protect human health and the environment from excessive overloading of various pollutants. Coagulation is an essential part of drinking water treatment process allowing the removal of suspended colloidal particles in water. The chemical coagulation is the process of destabilizing the colloidal particles suspended in raw water by the addition of coagulants. The coagulant dosage rate is nonlinearly related to raw water characteristics such as turbidity, pH, and alkalinity. The most common coagulants used are Aluminum Sulfate (Alum). Optimizing coagulation for selecting the best coagulation condition and coagulation dosage is important. The main test used to determine the optimum coagulation conditions is the jar test, which requires a long experimental time. Modeling can be used to overcome this limitation. In this study, a model for approximation of coagulant dosage rate in water treatment plant in Punalur, Kollam has been developed using the Artificial Neural Network (ANN). The ANN is known as an excellent estimator of nonlinear relationships between accumulated input and output numerical data. Using this nature of the ANN, the optimal coagulant dosing rate can be predicted from the operating data with accuracy and in time. Optimization of the Coagulation process using ANN can reduce the amount of chemicals being used, testing time and consequently reduced the operational cost. Document

Nondestructive identification of tea (Camellia sinensis L ) varieties using FT NIR spectroscopy and pattern recognition

Identification results of ANN model Artificial neural network (ANN) is a non-linear pattern recognition method. Many parameters exert to some extent certain influence on the perform- ance of ANN models. These parameters include the number of neurons in the middle layer, scale functions, learning rate factor, momentum factors, and initial weights (Blanco et al. 1999; Mouwen et al. 2006). In this work, the most classical Back Propagation Artificial Neural Network (BP-ANN) with 3 layers construction was used to construct the identification model. These parameters of the BP-ANN model were optimised by cross validation as follows: the number of neurons in the hidden layer was set to 8, the learning rate factor and momentum factor were set to 0.1 each, the initial weight was set to 0.3, and the scale function was set as ‘tanh’ function.

Modelling of the superplastic deformation of the near-a titanium alloy (Ti-2.5AL-1.8MN) using arrhenius-type constitutive model and artificial neural network

The flow behaviour of material during hot forming process is usually complicated. The hardening and softening mechanisms both mainly affect the strain rate and temperature [1–3]. The understanding of metallic alloys deformation behaviour at elevated temperatures helps to provide information about the metal forming processes. Three main categories of models are utilised to describe the stress flow behavior of metallic alloys: (1) physical based; (2) phenomenological and (3) artificial neural network constitutive models [4–8]. Phenomenological constitutive models are usually used in the simulation of hot forming processes due to their practicability and accuracy. For titanium alloys, the more significant part of literature on the constitutive modelling pays particular attention to α + β type alloys, especially Ti-6Al-4V titanium alloy [8–11].

The Adaptive Control of FES-assisted Indoor Rowing Exercise

The Adaptive Control of FES-assisted Indoor Rowing Exercise

Abstract — This paper describes the development of an adaptive control mechanism for FES-assisted indoor rowing exercise (FES-rowing). The FES-rowing is intro- duced as a total body exercise for rehabilitation of function of lower body through the application of functional elec- trical stimulation (FES). A model of the rowing ergometer with humanoid is developed using the visual Nastran soft- ware environment (vN4D). A fuzzy logic control (FLC) scheme is designed in Matlab/Simulink and adapted online by pre-training artificial neural network (ANN) to regulate the muscle stimulation pulse width required to drive FES-rowing. The ANN is used as an adaptation to the system that is required to account for muscle fatigue. The results signify that the adaptive control scheme is able to achieve and maintain better tracking performance. This study indicates that the adaptive control developed may provide an effective mechanism for automatically regulat- ing the stimulation pulse width for FES-rowing to over- come muscle fatigue.

Detection and Classification of Leukaemia using Artificial Neural Network

Detection and Classification of Leukaemia using Artificial Neural Network

Abstract: Blood is the very important biological fluid present in human beings, which has various functions. Leukaemia is a blood disease which affects the normal functioning of the blood. The number of cases of leukaemia reported every year in India is approximately close to 1 million. Detection and classification of Leukaemia into its subtypes manually by humans is difficult and time consuming. Hence an automatic system to identify and classify Leukaemia may overcome this drawback. Technique proposed in this paper aims at quick detection of leukaemia images, and classifies them into their respective subtype. This is achieved using image processing with the help of MATLAB software. Images used are microscopic blood smear images. Using K- means clustering algorithm images are segmented and a Artificial Neural Network (ANN) is designed based on the features extracted. This neural network is trained to classify the images into their respective type.
