This paper proposes an efficient method for the design of two-channel, quadrature mirror filter (QMF) bank. The design problem is formulated to minimize an objective function, which is a linear combination of pass-band error and stop-band residual energy of the low-pass analysis filter of the filter bank, and the square error of the overall transfer(More)
Throughput, Traffic Engineering and Load balancing concepts are very important in multi-path adaptive routing algorithm which stresses the need of multi-path adaptive routing algorithm as compared to single path routing algorithm. This paper evaluates the performance of multi-path adaptive routing algorithm in different situations like bottleneck link ,(More)
This paper includes a prospective approach of developing a trust based QOS protocol (TBQP) using meta-heuristic genetic algorithm for optimizing and securing MANET. Genetic algorithm will help in maintaining Quality of Service(QOS) by selecting a fittest i.e. shortest route hence providing better performance. Intelligent optimization approaches or meta(More)
OBJECTIVE To investigate the medicative effects of medium-polar (benzene:acetone, 1:1, v/v) extract of leaves from Stevia rebaudiana (family Asteraceae) on alloxan-induced diabetic rats. MATERIALS AND METHODS Diabetes was induced in adult albino Wistar rats by intraperitoneal (i.p.) injection of alloxan (180 mg/kg). Medium-polar extract was administered(More)
In this study, we systematically document the link between dust episodes and local scale regional aerosol optical properties over Jaipur located in the vicinity of Thar Desert in the northwestern state of Rajasthan. The seasonal variation of AOT(500 nm) (aerosol optical thickness) shows high values (0.51 ± 0.18) during pre-monsoon (dust dominant) season(More)
The main aim of Wireless sensor networks for the current approaches is mostly focused on sensor communication and service strength. Nevertheless, the applications of Wireless Sensor Networks (WSNs) are dignified to make revolution in cooperation with different goals. These methods, mostly deficient for various uses that restricted developers to control(More)
Orthogonal Frequency division multiplexing is a type of multicarrier modulation technique which is used in various wireless & telecommunication standards. In OFDM, higher data rate is split into several narrowband data stream that is transmitted simultaneously over a number of subcarriers. One major disadvantage of using OFDM is high Peak to Average power(More)
Cyber security has become a critical priority for electric utilities. With the increase in the use of intelligent measuring devices like PMUs and more advanced communications and information technology in smart grid, the overall attack surface has increased. Cyber attacks against synchrophasor system critical infrastructure are detrimental to the(More)
