In this paper comparative study of a recently proposed 5-Level T-Type Asymmetrical-H-Bridge (5-L-T-AHB) inverter is carried out for different modulation schemes based on PWM switching. The THD and the fundamental component of the output voltage for different modulation schemes at different frequencies is recorded and compared. The main advantage of high frequency PWM switching is that it reduces the THD in output current and voltages of a multi-level inverter. Matlab/Simulink is used for the simulation purpose. The results show that the variable frequency Phase-Opposite-Disposition PWM (PODPWM) modulation scheme based on triangular carrier wave have the minimum THD of 20.06% in voltage at unity modulation index. While the Third-Harmonic-Injected (THI) reference based PWM shows the highest THD of 25.97%. THI based PWM however, offers the highest fundamental component with 12% more output. Variation of THD and fundamental component is also seen for the varying modulation index (0.6-0.9). THD shows the decreasing trend while the fundamental component increases with increment in modulation index.

This paper deals with sensorless speed estimation of an Induction Motor with minimum mean square error. For sensorless speed estimation, Unscented Kalman Filter (UKF) is used. The performance of this filter depends on the process and the measurement noise covariance parameters of the estimator which estimates stator and rotor current, rotor flux, rotor speed, torque and it is also influenced by three scalar parameters such as alpha, beta, and kappa. As the selection of these values are not of a straight forward approach, an optimization algorithm such as Particle Swarm Optimization (PSO) is used to attain minimum error. The result shows that the filter performance is improved by using PSO tuning and gives optimized minimum error compared to conventional UKF under various machine operating conditions

Passive optical network (PON) employing coherent receiver is a promising technology for future high-speed optical access network. However, the commonly used phase and polarization diverse coherent receiver for long-haul communication is not suitable for cost stringent access network. Therefore, low-complexity (and thereby low-cost) coherent receiver design for access network becomes an attracting research field in current years. In this paper, we propose a simple heterodyne single-polarization coherent receiver by using a 3-dB coupler and a single-ended photodiode to realize a 25-Gb/s optical network unit (ONU) receiver. To make the receiver polarization-insensitive, Alamouti-coded dual polarization 14-Gbaud QPSK transmitter is used at the optical line terminal (OLT) side. By means of computer simulation, it is confirmed that the proposed ONU receiver allows a high split ratio of 1:512 for 30-km transmission length whereas a lower splitting ratio of 1:16 enable the use of long-reach PON (LR-PON) of 100 km.

Due to rapid increase in the population of India, the nation is at an urge to fulfil the needs of the entire population which has led to increase in urbanization, industrialization, deforestation, etc., that further has paved a way to increase in air pollution. Though the needs are fulfilled to some extent, the polluted air has a serious effect on the health of the human as well as the environment. This is the right time to walk through and understand the various sources of pollution, their effects on health of mankind and environment. This paper focusses on describing the various fundamental sources of air pollution, their threat towards the health of human and the guideline provided for those pollutants. We have also collected the concentration of the major air pollutants namely SO2, NO2 and Particulate Matter PM10 at various states of India using the monitoring stations’ data and a statistical analysis of the same is performed to identify the air quality index of the ambient air based on which the harmful effects are predicted. Also we have discussed the reality of the various sensors available for monitoring the concentration of air pollutants in the ambient air and the control measures that could be taken to reduce the concentration to safeguard the population from the threat.

Spam is a genuine and irritating issue for quite a longtime. Despite the fact that a lot of arrangements have been advanced, there still remains a considerable measure to be advanced in separating spam messages all the more proficiently. These days a noteworthy issue in spam separating also as content characterization in common dialect handling is the colossal size of vector space because of the various element terms, which is normally the reason for broad figuring and moderate order. Extracting semantic implications from the substance of writings and utilizing these as highlight terms to develop the vector space, rather than utilizing words as highlight terms in convention ways, could decrease the component of vectors viably and advance the characterization in the meantime. In spite of the fact that there are a wide range of techniques to square spam messages, a large portion of program designers just mean to square spam messages from being conveyed to their customers. In this paper, we present an effective way to deal with keep spam messages from being exchanged.In this work, a Collaborative filtering approach with semantics-based text classification technology was proposed and the related feature terms were selected from the semantic meanings of the text content.

Monitoring and coordinating the remote physical conditions of an environment is found difficult in many user applications. A wireless sensor network can be one of the best solutions in this application. Sensors are inter-connected together in the form of a mesh network to form Wireless Sensor Network (WSN). Transmitter and receiver are embedded in a single sensor called a "NODE" in other words called a transceiver, which is a battery operated and microcontroller enabled intelligent device. Further the nodes can also be interconnected in different topologies viz., Star, Ring, Mesh, etc.While many channel access protocols may be competent for using them in Wireless Sensor Networks, it is commonly found that IEEE 802.15.4 MAC (Medium Access Control) protocol is often used over IEEE standard 802.15.4 ZigBee protocol stack. As there are many other protocols reported in literature, it is felt necessary to revisit all the suitable protocols to find, if any, more efficient protocol for WSN exists. In this paper a study is carried out with CSMA, MACA and GENERIC MAC protocols for their suitability for WSN. The study is done by simulating these protocols in 802.15.4 ZigBee for different number of nodes from 15 to 30. The summary of the characteristics of all these protocols is presented. Qualnet 5.0.2 network simulator is employed to analyze the important characteristics like throughput, end-to- end delay, jitter, total packets received, etc., by varying the various parameters under low, medium and heavy loads.

In recent years several studies have been carried to explore the potential metrics of a mobile sink node to optimize the complex WSN routing and also to regulate the packet delivery rate among the sensor nodes. However, it has major limitations particularly in delay-bound applications, where all data gathered must be forwarded within a given time delay. These bound delays are dependent on the travelling path taken by the mobile sink. Here in order to regulate the mobile sink path a hybrid approach is proposed to address this challenge and also formulated new moving pattern where the mobile-sink node visits only rendezvous points (RPs), as opposed to travelling each nodes in WSN. Information from all other nodes all Sensor nodes that are not RPs forward their payload data via multi-hopping to the nearest RP. Then two basic fundamental problems are arises: computation of mobile sink travelling paths that can visit all RPs within a given time delay and conserving the energy consumption of mobile sink to improve the life time of the WSN. To address the first problem, a heuristic called adoptive rendezvous planning (WRP) is proposed, where each sensor node is assigned a priority corresponding to its hop distance from the mobile sink path taken and the traffic rate that forwards to the closest RP. And energy aware local routing is used for energy efficiency. Finally RP based mobile sink model is validated via extensive network simulation, and through simulation results we proved that proposed RP model allows mobile sink to gather all information within a given time while. Local routing for each RP node reduces energy consumption by 39% and increases network lifetime by 12%, as compared with all other state-of-the-art algorithms.

According to Central Electricity Regulatory Commission, India, all independent power producers should forecast their generation and submit a report regarding the same to RLDC (Regional Load dispatch Centre). If a deviation occurs between forecasted and actual generated power, the renewable energy operators should give penalty to RLDC. In the wind farm scenario, the wind farm operator should predict the wind power accurately to reduce the risk of uncertainty and penalties. To estimate the wind power precisely, the wind farm operators will depend on commercial forecasting methods. The selection of forecasting method is based on forecasting accuracy, system availability, Lead time etc. The aim of this work is to do wind power forecasting using hybrid VMD- ANFIS (Variational Mode Decomposition-Adaptive Neuro Fuzzy Inference System) in different time horizons. The power data for two years is obtained for a site in Maharashtra having 15 wind turbines, each having a capacity of 800kW. Three evaluation indices such as Mean Absolute Percentage Error (MAPE), Root Mean Square Error (RMSE) and % Revenue loss are calculated for one hour ahead and one day ahead forecasting and results are presented.
