In the process of modelling the path loss, the GSM 900 MHz signals are collected experimentally using Test Mobile System (TEMS) tool in the dense urban environment of Hyderabad city. In this paper, the best suited Cost 231 Hata empirical propagation model is implemented using three major dynamic neural networks namely, Focused Time Delay Neural Network (FTDNN), Distributed Time Delay Neural Network (DTDNN) which are feed forward dynamic neural networks and Layer Recurrent Neural Network (LRNN) which is a feedback dynamic neural network. The aim of these implementations is to minimise the errors between simulations and measurements. The dynamic neural networks are trained using Levenberg-Marquardt and Scaled Conjugate Gradient training algorithms. Comparisons are made by varying the number of neurons in the hidden layer and changing the training epochs. The performance is analysed in terms of correlation with the measured data, standard deviation, mean error between the targets and outputs and computation times. From the results it is inferred that, the best correlation between simulations and measurements is 0.9972, standard deviation of error (0.04) and mean error (−5.379e-5) are least for Layer Recurrent Neural Network, trained by Levenberg method, but at the cost of increased computation time. With respect to the feed forward dynamic networks, the results show that FTDNN trained by Levenberg algorithm has a better performance compared to DTDNN.","PeriodicalId":151809,"journal":{"name":"2016 IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics Engineering (UPCON)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117127704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve various problems in design phase, a number of tools and techniques are available and one of them is known as the use of design pattern, which helps to find a better solution for the problems, which are recurring in nature. It is often desired to detect design patterns from the source code of similar category of software, as it improves maintainability of source code of a software. In this study, mining of design pattern technique has been presented, which is based on supervised learning techniques as well as software metrics. During the pattern mining process, metrics-based dataset is developed. Subsequently, machine learning techniques such as Layer Recurrent Neural Network and Random Forest are applied for the pattern mining process.

The probability of its occurrence is usually dominated by the photovoltaic penetration however, as a direct consequence of this, load-inverter dynamic interactions alongside grid-side disturbances can also lead to anomalous instances that can become responsible for accidental island creation and one such anomaly has been described in this work. Given such dynamic behaviours occurring on photovoltaic inverter-integrated distribution feeders, threshold based classical islanding detection can not suffice and hence machine learning based techniques have began to be researched and adopted. However the orientation can be directed towards predictive approaches leveraging knowledge extraction from huge event data available in smart grids. Furthermore, unsupervised learning can be explored for real-time applications to enable self-learning and acting systems. This paper presents preliminary results of application of a self-organizing map neural network for preemptive detection of unintentional islanding by classifying the discovered islanding precursor from other power system events. Classification of a three phase short-circuit fault at the point of common coupling was found to be invariant to input feature reduction however the same gives contrasting results for the other two test cases investigated.","PeriodicalId":151809,"journal":{"name":"2016 IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics Engineering (UPCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125835588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It utilizes a simple DC-DC boost converter as a power conditioning stage between SPV array and the motor drive. The control of solar photovoltaic (SPV) array output power at maximum power point (MPP) and facilitating the soft-starting to the SRM drive, are two prime functions of the boost converter. The use of a 4-phase SRM drive minimizes the torque ripple and increases the number of strokes without incrementing the number of rotor poles. The low number of switches in a mid-point converter used to energize SRM phases further enhances the performance of the system. The speed control of the motor using the pulse width modulation (PWM) switching of split-capacitor converter eliminates the requirement of additional sensors on the motor to control its speed. The proposed water pumping system is designed, modeled and its performance is simulated on MATLAB/Simulink platform and its responses are analyzed, under the varying environmental conditions, which authenticate its appropriateness as an irrigation pump.","PeriodicalId":151809,"journal":{"name":"2016 IEEE Uttar Pradesh Section International Conference on Electrical, Computer and Electronics Engineering (UPCON)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115156787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel hybrid SVM-RBM classifier which recognizes the emotion for both live streaming video and stored video data using audio-visual features; thus recognizes the users' mood based on categorical emotion descriptors. The proposed method is experimented for human emotions recognition for live streaming data using the devices such as Microsoft Kinect and Web Cam.
