In the present scenario, CAD design for circuit components is an useful task. This paper deals with efficient software implementation of neural network in MATLAB environment with simulink to characterize coplanar wa veguide (CPW). This involve the task of implementation of perception neural network using back propagation algorithm until the simulation of the network using MATLAB. The back propagation algorithm used here has memory reduction feature and is the fastest training algorithm for the networks of moderate size. CPWis the one of the very few choices for using in millimeter wave frequency applications.

Hippocampus (HC) is one of the small brain components and its features majorly take part in diagnosing diseases such as Alzheimer and Dementia. The earlier detection of the size changes of HC leads to take preventive action against Alzheimer disease at initial stage. Thus the HC voxel quantification becomes essential to know the severity of the disease and thus induces computerized segmentation process. Several semi-automatic and automatic HC segmentation techniques proposed earlier. Though, it requires large memory space and high computational cost. This paper reduces the risk of searching a high configuration machine and reduces the cost by utilizing limited number of features. It is to be done by using some strategic features based on mathematical framework of wavelet, statistical features and gray level computations called level set. The features fed as input to the supervised machine learning model called backpropagation neural network. A deep study conducted to train the net and analyzed in various views. The results were compared with the similar existing models which were using Random forest, Quicknat and deep learning. The proposed machine learning model produces the higher and similar dice scores of existing model. The validation of the proposed method yields 85% of dice score and 96% of sensitivity and 96% of specificity.

Artificial intelligence technologies were confirmed as a useful tool for wastewater treatment, but its application in the electrochemical nitrate removal had less been reported. In this work, the artificial neural network in machine learning was used to construct the model, which combines the methods of electrochemistry and arti-ficial intelligence to achieve the prediction and intelligent control of nitrate removal. The control system consists of a prediction module with an artificial neural network (ANN) algorithm model and a control module. First, initial nitrate concentration, pH, time and current density were considered as input. An ANN algorithm using 7 hidden layers and a negative feedback regulation mechanism was developed to optimize the model and predict the nitrate removal rate. Results indicates that the proposed prediction model (4-7-1) yields a better coefficient of determination and lower root mean square error. The optimal set-points of the current density in the elec-trochemical process can be obtained according to the water quality change and qualified effluent quality using the ANN model. Also, the proposed intelligent control strategy can eliminate the influence of water quality change on nitrate removal and reduce energy consumption by 15.0 % compared to the post strategy. This work demonstrated the potential of artificial intelligence in the electrochemical process of nitrate removal.

Based on the risk evaluation index system of city fire, a comprehensive evaluation model with the adaptive genetic algorithm and BP neural network (AGA-BP) is established in the article. In former process of the hybrid algorithm, the adaptive genetic algorithm is applied to adjust weights and thresholds of the three-layer BP neural network and train the BP neural network for locating the global optimum, and the error back propagation algorithm is used to search in neighborhoods of the approximate optimal solution in the later process. The program written in VB6.0 is used to learn some samples of city fire risk according to the AGA-BP algorithm and the general BP algorithm. The results show that the learning precision of AGA-BP algorithm is more correctly than that of the general BP algorithm. The training speed and convergence rate of the former is significantly improved because of the combination of AGA and BP algorithm. It is helpful to realize automated evaluation for city fire risk.

This paper describes a new method to identify the type of fabric weave by using a neural network classifier. The characteristic parameters of the input layer, derived from fabric image, are composed of the Markov random field character, the difference between the maximum and the minimum of gray level projections in weft and warp directions, the area ratio of the brightness region to the total area in image, the weft and the warp yarn count. The experimental results show that the neural network classifier can effectively classify fabric weave with 98.33% of accuracy, which is helpful in the recognition of fabric weave parameters.

A new dynamic neural network was constructed by borrowing ideas from Jordan and Elman neural networks. To accelerate the rate of convergence and avoid getting into local extremum, a hybrid learning algorithm by Genetic algorithm (GA) and error back propagation algorithm (BP) was used to tune the weight values of the network. Finally, the improved neural network was utilized to identify the AUV hydrodynamic model. The simulation results show that the new network can remember the history state of hidden layer and tune the effect of the past signal to the current value real-timely. And in the presented network, the feedback of output layer nodes is increased to enhance the ability of handling signals. The neural network by hybrid learning algorithm improves the learning rapidity of convergence and identification precision.

In this paper we study the speed control of a DC motor with conventional (PID) and nonconventional (Neural Network – NN) methods. DC motor model and performance indicators criteria are defined. PID controller is tuned through Matlab scripting and tools and relevant results of closed loops system are received. For nonconventional method inverse model control schema is used, where a three layer NN presents the inverse model, and it is trained by back propagation algorithm. Simulation results are presented to compare the two control methods and conclude the benefits of NN usage in control. Considering the broad range of DC motor usage, where robotics is included, the study is presented as a way for improving the closed system's dynamics.
