The National University of Computer and Emerging science is a private research university and one of the leading technical institutions in Pakistan. It has multiple campuses based in cosmopolitan cities of Pakistan and has distinction of being the first multi-campus university in Pakistan.The Foundation for Advancement of Science and Technology was founded and established by BCCI financier Hasan Abidi that provided a large financial capital for university's purpose to promote research in computer science and emerging technologies in 1980. Established in 2000, it is regarded as one of the leading technical universities in Pakistan. It offers a wide range of programs for undergraduate, postgraduate, and doctoral studies in engineering, management science, business administration, humanities, arts and natural and social science. It is consistently ranked among one of the leading and top institutions of higher learning in the country, securing its top rank in the computer science/IT category by the HEC in 2010.The university's guidelines are committed to producing graduates of the highest order who may act as vanguard of the IT Revolution in Pakistan.

We investigate the exact solutions of a Bianchi type-I space-time in the context of f(R, T) gravity [1], where f(R, T) is an arbitrary function of the Ricci scalar R and the trace of the energy-momentum tensor T. For this purpose, we find two exact solutions using the assumption of a constant deceleration parameter and the variation law of the Hubble parameter. The obtained solutions correspond to two different models of the Universe. The physical behavior of these models is also discussed. © 2014, Pleiades Publishing, Inc. Source

This paper devotedly study the double diffusive Darcian convection flow of Eyring-Powell fluid from a cone embedded in a homogeneous porous medium with the effects of Soret and Dufour. Arising set of non-linear partial differential equations are transformed through a suitable self-similar transformation into a set of nonlinear ordinary differential equations. Further, the numerical and the analytical solutions of the governing equations are elucidated by using numerical method as well as non-perturbation scheme. Numerical values are presented through tables for the skin friction coefficients, Nusselt number and Sherwood number. The obtained results are validated by comparing the analytical results with previously published results obtained by bvp4c for the numerical values of physical quantities. The effect of various parameters on the velocity, temperature and concentration profiles is discussed and also shown graphically. © 2015 Author(s). Source

Swarm intelligence is a relatively novel field. It addresses the study of the collective behaviors of systems made by many components that coordinate using decentralized controls and self-organization. A large part of the research in swarm intelligence has focused on the reverse engineering and the adaptation of collective behaviors observed in natural systems with the aim of designing effective algorithms for distributed optimization. These algorithms, like their natural systems of inspiration, show the desirable properties of being adaptive, scalable, and robust. These are key properties in the context of network routing, and in particular of routing in wireless sensor networks. Therefore, in the last decade, a number of routing protocols for wireless sensor networks have been developed according to the principles of swarm intelligence, and, in particular, taking inspiration from the foraging behaviors of ant and bee colonies. In this paper, we provide an extensive survey of these protocols. We discuss the general principles of swarm intelligence and of its application to routing. We also introduce a novel taxonomy for routing protocols in wireless sensor networks and use it to classify the surveyed protocols. We conclude the paper with a critical analysis of the status of the field, pointing out a number of fundamental issues related to the (mis) use of scientific methodology and evaluation procedures, and we identify some future research directions. © 2011 Elsevier Inc.

The main purpose of this paper is to explore the exact solutions of Bianchi type V spacetime in f(R, T) theory of gravity (Harko et al. 2011). In this context, two exact solutions are investigated using assumptions of the variation law of Hubble parameter and constant deceleration parameter. The first solution corresponds to a singular model while the second solution gives a non-singular model of the universe. The physical quantities for these models are calculated. Moreover, the energy density and pressure of the universe is discussed in each case. © 2014, Springer Science+Business Media New York. Source

The main purpose of this paper is to investigate the exact solutions of plane symmetric spacetime in the context of f(R,T) gravity [Phys. Rev. D 84 (2011) 024020], where f(R,T) is an arbitrary function of Ricci scalar R and trace of the energy momentum tensor T. We explore the exact solutions for two different classes of f(R,T) models. The first class f(R,T) = R + 2f(T) yields a solution which corresponds to Taub's metric while the second class f(R,T) = f1(R) + f2(T) provides two additional solutions which include the well known anti-deSitter spacetime. The energy densities and corresponding functions for f(R,T) models are evaluated in each case. © 2016 Chinese Physical Society and IOP Publishing Ltd. Source
