Anand Engineering College, also known as AEC, Agra, is an engineering college in Agra, India. It is situated at the 18 km milestone on the Agra-Delhi highway , spread across 30 acres at a scenic location overlooking Keetham Lake, one of the greenest areas around the city of Agra. The college, housed in its own building with 500,000 sq ft of covered area, was founded in 1998, and the first students graduated in 2002.It is affiliated to Uttar Pradesh technical university .

The present study deals with dissipative future universe without big rip in context of Eckart formalism. The generalised Chaplygin gas, characterised by equation of state, has been considered as a model for dark energy due to its dark-energy-like evolution at late time. It is demonstrated that, if the cosmic dark energy behaves like a fluid with equation of state p=ωρ; ω<-1 as well as Chaplygin gas simultaneously then the big rip problem does not arise and the scale factor is found to be regular for all time. © 2011 Springer Science+Business Media, LLC.

The Bianchi type III dark energy model with constant deceleration parameter is investigated. The equation of state parameter ω is found to be time dependent and its existing range for this model is consistent with the recent observations of SN Ia data, SN Ia data (with CMBR anisotropy) and galaxy clustering statistics. The physical aspects of the dark energy models is discussed. © 2010 Springer Science+Business Media, LLC.

We have searched for the existence of the late time acceleration of the universe with string fluid as the source of matter in Bianchi - V space-time. To derive a deterministic solution, we choose the scale factor to be an increasing function of time that yields a time dependent deceleration parameter, representing a model which generates a universe showing a transition from an early decelerating phase to a recent accelerating phase. The study reveals that strings dominate the early universe and eventually disappear from the universe for sufficiently large times, i.e. in the present epoch. This picture is consistent with current astronomical observations. The physical behavior of the universe is discussed in detail. © 2012 National Astronomical Observatories of Chinese Academy of Sciences and IOP Publishing Ltd..

This paper presents a new digital distance relaying scheme which takes care of a simultaneous open conductor and ground fault occurring coincidently on the same phase at the same point on a series-compensated double-circuit line. The effect of series compensation, mutual zero-sequence coupling, remote infeed/outfeed, and fault resistance on the relay reach has been considered by the proposed scheme. The conventional digital distance relay having facility of series compensation fails to provide adequate protection in the presence of such conditions. The proposed scheme is based on the derivation of the compensated values of impedance using symmetrical component theory. To validate the proposed scheme, numerous computer simulations have been carried out using MATLAB/SIMULINK software on an existing 400-kV, 300-km-long series-compensated double-circuit transmission line. At the end, a comparative evaluation between the proposed scheme and the conventional scheme having a facility of series compensation is carried out. Simulation results demonstrate the effectiveness of the proposed scheme since the percentage error is within ±4.19%. © 2012 IEEE.

Bianchi type V matter filled universe with varying λ in general relativity are investigated by using the law of variation for the generalized mean Hubble's parameters. This yields the constant value of deceleration parameter and generates two types of solutions for the average scale factor one is of power law type and other is of exponential type. The cosmological constant is found to be a decreasing function of time, which is supported by results from recent type Ia supernovae observations. Also it has been found that cosmological constant λ(t) affects entropy. Some physical and geometric behaviour of the models are discussed. © lectronic Journal of Theoretical Physics.
