A fuzzy confusion matrix based cursive handwritten text categorization has been implemented. Printed text is obtained from handwritten text through Modified Optimal Clustering Algorithm (MOCA). Optimal Clustering Algorithm (OCA) groups texts into different subject categories. Learning is conducted to extract the attributes along with corresponding weights for each subjects. Fuzzy confusion matrix has been used to measure several performance metrics with Holdout method. These are satisfactory. Over and above the text learning and recognition time is very less making the system efficient also.

The paper proposes an algorithm for delineation of ECG data based on multiresolution Discrete Wavelet Transform (DWT) and relative magnitude and slope comparison on selected time windows. The data is initially denoised using linear and nonlinear wavelet based filtering techniques to eliminate both low and high frequency ECG artifacts and also reduce the wide-band noises. The delineation algorithm involves combining specific detailed sub-bands of the denoised data and applying proper thresholds and time windows to identify the wave boundaries (QRS, P and T waves). The characteristic points of each wave (peaks, onset and offset) are then detected using relative magnitude and slope comparison within each wave. The algorithm yields sufficiently high detection sensitivity of 99.85% for QRS regions and also efficiently identifies the P and T wave features, as tested with the MIT-BIH arrhythmia database.

This paper presents development and performance analysis of a sensor node including accelerometer, temperature and humidity sensors for wireless sensor network (WSN) system intended for structural health monitoring (SHM) application. The developed prototype integrates software and hardware based on ARM controller, having excellent processing capability in terms of increased on board RAM and better power management facility. Data from sensor nodes are reliably transmitted to the base station, i.e. sink placed at a distance of about 30m. The system is verified using accelerometer data received at the base station through Fast Fourier Transform and found equivalent with that of a standard vibration data logger. Accelerometer data has also been explored in time-frequency domain using wavelet transform. The study also points out the best wavelet basis in the parlance of low frequency SHM applications.

There are many engineering simulations and scientific computing applications where large linear system of equations are to be solved. With the generous development in scientific computing the use of large linear system of equations also increases. There are many solvers for solving these equations. Jacobi is one of the important solvers for solving linear system of equations. Jacobi method is more efficient when implemented in a pipelined manner in an FPGA and it also shows more parallelism In this paper hardware based implementation of Jacobi solver is discussed. The main idea of Jacobi to obtain preference is its computation that can be trivially done in parallel.

This paper presents a new way to design PID controller for both integer order and fractional order with a time delay for a typical interacting cylindrical tank system using MATLAB FOMCON toolbox. Here, our work aims to study the performance characteristics of integer order and fractional order PID controller on the current integer order plant obtaining minimum objective function by Nelder - Mead optimization technique with different performance metrics ISE, ITSE and IAE. Next our work shows to make comparison between integer order PID controller based on AMIGO model performance and fractional order PID controller on time domain characteristics. The proposed method aims finally to analyze overall desired performance on fractional order PID controller by adding two extra degrees of freedom over the integer order PID controller with different performance criteria.

Integration of Photovoltaic system to grid through voltage source inverter is presented in this paper. The PV-grid system is connected to nonlinear load. To reduce the harmonics due to nonlinear load, a filtering technique is employed. This is nothing but one voltage source inverter which act as active power filter. Incremental Conductance based MPPT is employed which gives the reference value of dc capacitor voltage for the voltage source inverter. PID controller is employed to track reference dc link voltage. Computation of the reference source current is based on the calculation of the active component of current. The actual source current and reference source current are compared using adaptive band hysteresis controller. The value of hysteresis band which depends up on the system parameter, for which constant switching frequency is obtained. The complete system illustrates that the PV system is integrated to grid with reduced harmonic distortion of 4.25% at unity power factor.

Dynamic and diverse disruptions are continuously challenging the functionality of Electrical Grid. Climate change and integration of modern communication technologies in the grid raises new challenges, and past few year events highlight the need to address these challenges especially for the electrical power distribution system. Quick recovery of the grid after an outage is vital in order to minimize its economic, social, and political impacts. Resilience is the terminology that evaluate response and recovery process. This paper proposes a framework for the resilience performance analysis of the electrical grid considering different aspects that evolved around the response of the grid against any kind of disruption. The quality of the outcome after response and speed of the response is affected by the cause of disruptions, need of resources to response against disruptions, the capability of the resources and its performance. Speed and quality of the response are the most used measure of resilience. Relevance of the aspects that considered in the framework is also the part of this study.

This paper presents a simple, cost-effective technique of stator winding inter-turn fault detection that is applied to a single-phase induction machine while in operation. The technique emphasizes on sensing the stator current of the induction motor and analyzing the current for detecting the fault. The technique is minimalist and uses less number of sensors and thus cost-effective and can also be easily implemented. The technique is also non-invasive and thus less intricate. The proposed scheme can be used on-line for fault diagnosis. Experimental studies on a machine with main winding inter-turn fault and comparison of the findings with a healthy machine of similar ratings shows the effectiveness of the proposed method.

In general the delay in the sensor response affects the close loop performance of a control loop resulting in overshoot and prolonged settling time. In this paper the effect of online compensation of sensor delay on the close loop performance has been studied. The shell and tube heat exchanger has been considered as the candidate process since it is one of the most common processes in chemical or other industries where heat transfer is required. The thermocouple is considered as the sensor with an appreciable amount of delay in its response. It is shown in this paper that the close loop response with the compensated sensor has been improved noticeably, in terms of less overshoot and faster settling time, with respect to that of the uncompensated sensor.
