Multilevel inverter is a new breed of power converter which is suited for high power applications. The various topologies of multilevel inverter are diode - clamped, capacitor clamped and cascaded H-bridge inverter. It is an effective solution for increasing the number of levels in output waveform with reduced dc sources and switching elements, thereby dramatically reduces harmonics without increasing...
The authors of [1] proposed the novel balancing technique of the sub module capacitor of Modular Multilevel Converter (MMC) which based on sorting of capacitor voltages, detection of current and the selection of the sub modules. In this paper the versatility of the balancing method has been checked by applying it to one of the applications i.e MMC -HVDC. The comprehensive simulations have been carried...
Several attributes of Quality of Service (QoS) of web service choreography have been proposed based on its meta model. These attributes are single valued and have been primarily used for dynamic selection and substitutivity of competing web service. It is more natural to specify the values of these attributes in terms of their minimum and maximum values either desired by the service requestor or advertised...
Road accident analysis is very challenging task and investigating the dependencies between the attributes become complex because of many environmental and road related factors. In this research work we applied data mining classification techniques to carry out gender based classification of which RndTree and C4.5 using AdaBoost Meta classifier gives high accurate results. The training dataset used...
This paper proposes a sliding mode control scheme for effective speed tracking by obtaining ripple free torque through the inner loop current control for a BLDC motor. The second order mathematical model of the BLDC motor is developed for simulation purposes. Two first order sliding controllers based on the exponential reaching law algorithm are proposed for the inner loop current control and also...
Mobile ad hoc network requires lots of attention towards secure reputed routing. This paper proposed a novel reputed e-ARAN scheme to detect and handle authenticated selfish nodes, based on reputed OCEAN scheme. With description of all four phases of reputed e-ARAN it also proves that the proposed scheme gives better end-to-end delay and throughput as compare to existing ARAN protocol.
From thousands of years back our predecessors have invented several ways of passing information in hidden form with other objects like papyrus scroll, cryptex etc. As decades crossed through earth's vein we are getting matured and invented several steganographic systems for message passing. The availability of internet in every corner of the universe forced the user of steganographic systems to invent...
