In modern world intelligent control has become a priority, although the services for providing energy are still being controlled with conventional methods. The conventional method is expensive and time consuming as well as it requires man power for monitoring and data collection of the consumers which may also lead to human errors. The proposed GSM based system integrates digital energy meters installed at consumer unit with an electric supply companies to monitor, profile and control energy flow with the help of Graphical User Interface (GUI). In this two-way communication system, the GSM network is utilized to profile the energy flow with the help of SMS to the energy supplier and showing it on the monitor of the energy supplier using the GUI and can also communicate with the user via SMS. Relay circuit and LCD display is provided to update information like Voltage, Current, Units and billing or sudden power cut to the energy supplier company and is displayed on GUI. Nowadays the main problem in energy supply is that of power theft being done on various scales. Our system can also send an alert to the energy supplier in case of any power theft at the consumer side and cutoff the supply automatically until the power theft is not being cleared. This research highlights the general theory of energy metering system and focuses on our user friendly low power energy metering system design, implementation, power theft control and results.

This study is dedicated to analyze the heat transfer and flow of ethylene glycol and water based copper (Cu) nanoparticles between two squeezed parallel disks with suction/injection effects. The lower disk is assumed to be permeable. Additionally, we have considered the influence of MHD to keep the metallic particles in charge. These particles are normal to the surface and strongly effected by magnetic field. Constructed mathematical model consist of system of partial differential equations in cylindrical coordinates, based upon momentum and energy equations. The governing equations reduced to a nonlinear set of ordinary differential equations. The said set of nonlinear equations consists of squeezing number S, Hartmann number (M), nanoparticle volume fraction / and suction/injection parameter (A) tackled by least square Galerkin method (LSGM). The outcomes are analyzed by means of temperature and velocity profiles for every Cu-water and Cu-ethylene glycol nanofluids. The heat transfer and flow behavior at the surface are studied via graphical plots for local Nusselt number and skin friction. It is observed that local Nusselt number achieved from Cu-water remain lesser than Cu-ethylene glycol while the behavior for skin friction coefficient is totally opposite. We support our theoretical study via a detailed evaluation of outcomes. The obtained results via least square Galerkin method (LSGM) are compared with RK (order-4) and already existing results. Moreover, graphical representation, the error, convergence and comparison analysis of outcomes endorsing that the least square method is extremely effective. The suggested method could be extended to other nonlinear problems

The main emphasis of present work is to investigate the velocity and thermal slip effects on Casson nanofluid with heat and mass transfer phenomena over an inclined permeable stretching cylinder. The cylinder is subject to transverse magnetic field. Buongiorno’s model is adapted to study the Brownian motion and thermphoresis effects which play a dominant role in nanofluid. Governing set of equations are derived in terms of partial differential equations for Casson nanofluid model, consisting continuity, momentum, energy and concentration equation which are transformed into set of coupled nonlinear ordinary differential equations using similarity transformation. The numerical solution is obtained using collocation method. The literature survey shows that the present problem has not been studied before. Physical quantities of interest are nanofluid velocity, temperature, concentration, skin friction coefficient, Nusselt number and Sherwood number which are analyzed through graphs against the emerging physical parameters. It is found that Nb and Nt play a dominant role within the thermal and concentration boundary layer regions. In the same manner, suction parameter and both velocity and thermal slip parameters depicts the dynamic effects in the entire domain of stretching surface of the cylinder.

This article is devoted to analyze the magnetic field, slip, and thermal radiations effects on generalized three-dimensional flow, heat, and mass transfer in a channel of lower stretching wall. We supposed two various lateral direction rates for the lower stretching surface of the wall while the upper wall of the channel is subjected to constant injection. Moreover, influence of thermal slip on the temperature profile beside the viscous dissipation and Joule heating is also taken into account. The governing set of partial differential equations of the heat transfer and flow are transformed to nonlinear set of ordinary differential equations (ODEs) by using the compatible similarity transformations. The obtained nonlinear ODE set tackled by means of a new wavelet algorithm. The outcomes obtained via modified Chebyshev wavelet method are compared with Runge-Kutta (order-4). The worthy comparison, error, and convergence analysis shows an excellent agreement. Additionally, the graphical representation for various physical parameters including the skin friction coefficient, velocity, the temperature gradient, and the temperature profiles are plotted and discussed. It is observed that for a fixed value of velocity slip parameter a suitable selection of stretching ratio parameter can be helpful in hastening the heat transfer rate and in reducing the viscous drag over the stretching sheet. Finally, the convergence analysis is performed which endorsing that this proposed method is well efficient.
