In wireless sensor networks, the transmission of data packet devoid of pre-defined scheduled time may lead to unwanted collision and also it can result in under-utilization of the channel. Hence in this paper, we proposed the hybrid Hierarchical adaptive Time Division Multiple Access (TDMA) Medium Access Control protocol (MAC) in Wireless Sensor Networks. In this technique, the node with higher weight value is chosen as cluster head, the value may be calculated from residual energy and delay between the successive transmissions. When the cluster head receives the data packet, it identifies the number of data packets in the queue of the node and assigns TDMA slots to its member nodes based on the queue size and channel utilization. If the queue size value is below a minimum threshold value, slots are not allocated to that node in order to prevent under-utilization. In case of the under utilization the nodes in the network follows the existing CSMA mechanism. To prevent the total power consumption in cluster, collision prevention technique is executed. Based on the simulation results, it is proved that the proposed HAMAC reduces the power interference and enhances the packet throughput, by the way increase the life time of the wireless sensor networks. © 2016 American Scientific Publishers All rights reserved.

Economic Load Dispatch (ELD) is an imperative assignment in contemporary aggressive power demand market. Dearth of power generation in all dimensions of energy resources will result escalating in generation cost wants the optimal power dispatch at minimum fuel cost. Owing to the confined optimum convergence, the predictable optimization methods are not proficient to crack such problems. Evolutionary optimization techniques are proved to be superior to the conventional techniques to solve ELD problems. Differential Evolution Algorithm (DEA) is one of the foremost and recent evolutionary techniques in modern optimization state of affairs. The application of DEA in multi directional ELD problem has been technologically summarized in this paper. © 2017 Elsevier Ltd.

Medical information and health care data is crucial for research but maintaining privacy of the individual is even more important. Recent technologies have lead to storage and usage of huge amount of personal details of users/customers using the shared access media by World Wide Web (WWW), there is a possibility of misuse of individual's data by the competing organizations or the attackers. Privacy preserving techniques should ensure that an individual's sensitive data is not directly used for publication or processing. Privacy preserving should be integrated while mining of these databases and this new domain is called as Privacy Preserving Data Mining (PPDM). In the proposed framework, a feature suppression technique using memetic algorithm and a generalization technique for anonymization is proposed. Memetic Algorithm which uses a statistical based local search on globally searched features by Ant colony Optimization (ACO) is proposed to suppress the features which do affect the classification accuracy. An optimal generalized feature set obtained by the proposed Memetic algorithm is used for classification. The results of classification with manually selected features, ACO based features set and proposed memetic-ACO feature set are compared for parameters such as average classification accuracy, average precision and average recall. The proposed scheme did not reduce the classification accuracy but actually increased the accuracy by 0.22% which is significant for very large datasets. © Copyright 2016 American Scientific Publishers All rights reserved.

In this, a combined experimental and theoretical study on molecular structure and vibrational analysis of P-nitrobenzotrifluoride (PNBTF) is reported. The Fourier transform infrared and FT-Raman was recorded in the solid phase. The molecular geometry and vibrational frequencies of PNBTF in the ground state have been calculated by using density functional method (B3LYP) with 6-311++G(d,p) as basis set. Comparison of the observed fundamental vibrational frequencies with calculated results by density functional methods indicates that B3LYP/6-311++G(d,p) is superior to other methods for molecular vibrational problems. The bioactivity of the compound is analyzed by the HOMO-LUMO analysis. The reactivity sites are identified by mapping of electron density into electrostatic potential surface (MEP). Besides, 13C and 1H nuclear magnetic resonance (NMR) chemical shifts are calculated by using the gauge-invariant atomic orbital (GIAO) method. Furthermore, the compound can be used as a good nonlinear optical material due to the higher value of first hyperpolarizability. Solventation effect of NMR spectra by CPCM model of P-nitrobenzotrifluoride has been analyzed. © 2013 Elsevier B.V. All rights reserved.

This paper deals with the application of Six-Sigma methodology to the flywheel casting process in foundry to minimize the defects in this process. The primary tools used in this interventionist process were the process map, cause-and-effect matrix and the failure mode effective analysis. The present study proposes to measure the performance criteria of the process through investigating the effect of working parameters, namely, moisture content, green strength, permeability, and loss on ignition on sand preparation. The experimental results were statistically analyzed and modeled through response surface methodology (RSM). Based on the findings, the optimized process parameters were taken for experiment and better performance obtained in the production process was confirmed. The comparison between the existing process and the proposed process has been attempted in this paper and the results have been discussed in detail. © 2013 Springer-Verlag London.

From the past few years, vehicle plate recognition is becoming the most challenging and interesting topic of surveillance. It is challenging because number plate comes in different size, shape and written in different font style. It is interesting because of its use in security applications. In this paper we have proposed a robust and simple approach based on edge detection and segmentation with morphological operations. Our suggested approach is performed in three steps: In first step detection of license plate is performed. In second step, segmentation of character is done from detected number plate. While in the third step, recognition of segmented character is performed. We have tested several images taken under different weather condition to check the validity, robustness and efficiency of our algorithm. The result of our experiments is very satisfactory and opens the track of our algorithm to be used in many real life applications. © 2016 IEEE.

Powder forming process is used for fabrication of bulk ceramic components. Optimization of powder forming process parameters in the fabrication of alumina-zirconia composite used in orthopedic implants is done for desired physical property. In this research work,process parameters such as composition of zirconia, compaction pressure and sintering temperature were analyzed using Response Surface Method (RSM). The physical properties such as density, porosity and water absorption characteristics of the proposed composite were studied. To study the influence of the different process parameters over the physical properties of the fabricated composites materials, experimental runs were framed by using Box behnken method. Three factors and two levels were selected with a total of 17 runs and their consecutive tests were carried out. The validity of the model was checked and the significant parameters were identified using Analysis of variance (ANOVA). The results indicate that the sintering temperature is influencing predominantly the physical properties of composites compared to other process parameters. © (2014) Trans Tech Publications, Switzerland.

To take out a variable frequency variable amplitude output voltage a new single-phase H-bridge multilevel inverter (MLI) topology is constructed through VFISCPWM modulated semi-cross switched voltage sources along with a hybrid pulse width modulation (PWM) strategy. The principle avoids a shrewd attitude to employ PWM approach only for a meticulous H bridge that serves to produce the desired level while the remaining add-on modules function with the theory of basic switching. The use of reduced number of switching devices involves for a precise number of output voltage levels in comparison with conservative MLIs. The design of the hybrid PWM appropriate to power the suitable switches add strength to its formulation in the sense it requires only either addition or subtraction to generate the square wave modulated pulses for the power devices in the other units other than that responsible for offering the preferred level of output voltage. Simulation results are obtained from MATLAB SIMULINK environment and validated predict the emergence of a novel variety of MLIs and falsify a diverse dimension for inverter interfaces in power control applications. © 2016 IEEE.
