In the present study, theoretical approach used to solve the problem of one dimensional non linear partial differential equation for moisture content of soil. The mathematical formulation leads to a non linear partial differential equation and its solution have been obtained by homotopy analysis method. The analytical results of the equation have been obtained in term of negative exponential terms,...

Emerging Mobile Based Technology (MANET) gives Revolutionary Changes in the computer world. As research has moved, several prospects has been explored and yet more to be explored. MANET is based on IEEE 802.11. In MANET, the important thing is that all the nodes are mobile and due to this, it is hard to secure the communication. Power saving is also a major problem in MANET because mobile nodes work...
In cloud computing, data generated in electronic form are large in amount. To maintain this data efficiently, there is a necessity of data recovery services. To cater this, in this paper we propose a smart remote data backup algorithm, Seed Block Algorithm (SBA). The objective of proposed algorithm is twofold, first it help the users to collect information from any remote location in the absence of...
Increasing need of data protection in computer networks led to the development of several cryptographic algorithms hence sending data securely over a transmission link is critically important in many applications. Hardware implementation of cryptographic algorithms are physically secure than software implementations since outside attackers cannot modify them. In order to achieve higher performance...
This paper presents a comparator-analog multiplexer based 6 bit analog to digital converter (ADC) using repetitive block of 2*1 multiplexer. The multiplexer is designed using transmission gates while subtractor is designed from a 2 stage op-amp. Such an approach results in high speed and less chip area. The comparator in the proposed work is latch based one making the overall design speed faster....
Two-dimensional coherent spectroscopy on a series of quantum dot samples with different morphology reveals that biexciton binding is independent of the details of confinement in InAs dots, in contrast to the behavior in GaAs dots.
The frequency-frequency correlation function for excitons in a GaAs quantum well is measured using optical two-dimensional Fourier transform spectroscopy and a numerical fitting procedure. We also report frequency-frequency correlation functions for biexciton and two-exciton states.
The shortage of cheap and abundant energy in India is currently a major roadblock in achieving higher economic growth. Free fuel based solar and wind energy sources can provide sustained economic growth. Lack of understanding regarding the role of photovoltaics (PV) as a major current and future energy conversion technology by policy makers and top businessmen in India is a fundamental roadblock in...

A MANET is a collection of mobile nodes communicating and cooperating with each other to route a packet from the source to their destinations. A MANET is proposed to support dynamic routing strategies in absence of wired infrastructure and centralized administration. In such networks, limited power in mobile nodes is a big challenge. So energy efficient techniques should be implemented with existing...
Distance relays is exclusively used for the protection of HV and EHV line from last few decades. As a result of extensive research studies the distance relays have been upgraded to a distinct level. Introduction of synchronized measurement in power system has opened the new area of research in protection of transmission line. To enhance the power transfer capability of line the shunt Flexible AC Transmission...
Increase in transmittable power, improvement in system stability, reduction in transmission losses, enhancement in voltage control and more flexible power flow control are the factors which promote the use of series compensator on transmission lines. However the presence of series compensator on the line affects the distance protection of the line in the form of under-reach or over-reach of the distance...
A polyurethane/ Polysulfone/ Multi-walled carbon nanotube blend polymer nanocomposite of thickness 25µm were prepared by solution mixing method.
