In this paper, we discussed the peristaltic MHD flow of an incompressible and electrically conducting Williamson fluid in a symmetric planar channel with heat and mass transfer under the effect of inclined magnetic field. Viscous dissipation and Joule heating are also taken into consideration. Mathematical model is presented by using the long wavelength and low Reynolds number approximations. The differential equations governing the flow are highly nonlinear and thus perturbation solution for small Weissenberg number (We < 1) is presented. Effects of the heat and mass transfer on the longitudinal velocity, temperature and concentration are studied in detail. Main observations are presented in the concluding section. The streamlines pattern is also given due attention. © 2016 Author(s).

We studied heat transfer on MHD convective flow of viscous electrically conducting heat generating/absorbing fluid through porous medium in a rotating channel under uniform transverse magnetic field normal to the channel and taking Hall current. The flow is governed by the Brinkman's model. The diagnostic solutions for the velocity and temperature are obtained by perturbation technique and computationally discussed with respect to flow parameters through the graphs. The skin friction and Nusselt number are also evaluated and computationally discussed with reference to pertinent parameters in detail. © 2017 Author(s).

We considered the transient MHD flow of a reactive second grade fluid through porous medium between two infinitely long horizontal parallel plates when one of the plate is set into uniform accelerated motion in the presence of a uniform transverse magnetic field under Arrhenius reaction rate. The governing equations are solved by Laplace transform technique. The effects of the pertinent parameters on the velocity, temperature are discussed in detail. The shear stress and Nusselt number at the plates are also obtained analytically and computationally discussed with reference to governing parameters. © 2017 Author(s).

In this paper, we discussed the theoretical and computational study of peristaltic hemodynamic flow of couple stress fluids through a porous medium under the influence of magnetic field with wall slip condition. Actually this study is motivated towards the physiological flow of the blood in the micro circulatory system by taking account of the particle size effect. We consider the Reynolds number is small enough and the wave length to diameter ratio is large enough to negate inertial effects. The governing equations for the couple stress fluid flow through porous medium based on stoke constitutive equations and Brinkman model. The exact solutions for axial velocity, pressure gradient, frictional force, stream function and mechanical efficiency are obtained analytically, its behaviour computationally discussed with reference to different physical parameters reflecting couple stress parameter, Hartmann number, permeability parameter, slip parameter as well as amplitude ratio on pumping characteristics and frictional force, stream lines pattern and trapping of peristaltic flow pattern are studied with particular emphasis making use of graphs. © 2016 Author(s).

The geographical disasters in past few years have increased in due to environmental effects, which leaves many sufferers isolated from rest systems. It is a challenging issue for both military and recovery teams to re-stabilize the situation in a non-communication environment due to infrastructure loss. Re-stabilizing the system will be slow and expensive, so in such cases short range, mobile devices can be very useful to construct a multihop mobile ad hoc network (MANET) for quick connectivity to reach the sufferers. But this emergency communication system drives an uncertainty to the network stability due to its power resource constraints. From the route discovery analysis, we observed that 5-10% of the power loss occurs during route discovery operation itself by each node to perform the broadcasting, receiving and replying tasks. In totality, it costs a huge power loss in case of the large scalable network. Wetar get this problem and propose a Power Saving Mechanism (PSM) for route discovery through reducing the number of rebroadcasting nodes during route discovery process. The proposal will improve the network lifetime and throughput through reducing the power consumption. An evaluation result of scalability and mobility variation shows the proposal efficiency. © 2017 IEEE.

Multimedia transmission over Mobile Ad-hoc Networks (MANETs) is crucial to many applications. However, MANETs possess several challenges including transmitting large size packets, minimizing delay, loss-tolerant and buffer size estimation. For effective multimedia transmission, delay should be minimized and packets should be received in the defined order. The existing standards such as 802.11b and 802.11e perform well in wireless networks, but exhibit poor response in MANETs for multimedia traffic, especially in multi-hop networks. In this paper, we first establish the dependency of delay on buffer size and packet size, and then present a delay optimization approach for multimedia traffic in MANETs. We use Knapsack algorithm for buffer management to maximize the in-order packets and minimize the out-of-order packets simultaneously. Our approach exploits the buffer internals and dynamically adjusts the buffer usage so that a node transmits the packets in the desired order to its successive nodes. Careful estimation of packet size and buffer size helps in minimizing the delay, improving the capability of receiving packets in the correct order and reducing out-of-order packets in the buffer at intermediate nodes. Our approach also controls the loss of multimedia data packets during transmission. We validate our approach with real-world examples using network simulator. © 2015 Elsevier Ltd.

The present data driven business intelligent systems and associated technologies and protocols are not suitable for agri-business. Distribution of data, poor infrastructure, lower e-readiness and complexity of agribusiness problems pose special challenges for creating and managing data driven agri-business intelligence. A Novel RAIN computing based framework to provide data driven mobile commerce intelligence for agri-businessmen along with a case study was presented in this article. © 2014 IEEE.

For increased profitability and sustainability, the E-commerce systems should be backed by efficient and effective Supply Chain Management and Value Chain Management Systems. However, it is very difficult to build such systems as the functions are complex and systems are CAPEX and OPEX intensive. To overcome these problems, an inexpensive supply chain management system was designed and developed successfully with Real-time Advance Inexpensive Network Computing. The results of the research work are presented in this article. © Springer India 2016.

Though workflow technology is being used for automating enterprise activities but its uses in healthcare domain is at nascent stage. As healthcare workflow directly deals with human life, therefore it must take precautions to undesired situations during its executions. In this paper we analyze the domain and mathematical modeling is done. We present a comprehensive view on genesis of exceptions and corresponding actions. The concept is further explained with the help of a case study. © Springer-Verlag Berlin Heidelberg 2011.
