In this article, we present a system-level characterization of the energy consumption for sensor network application scenarios. We compute a power efficiency metric—average watt-per-meter—for each radio transmission and extend this local metric to find the global energy consumption. This analysis shows how overall energy consumption varies with transceiver characteristics, node density, data tr...

Experimental research on the Pb phase coarsening of eutectic Pb/Sn flip chip solder joint under current stressing is reported. Phase growth is observed under different current densities and temperatures. Higher current density leads to faster grain coarsening. Based on the test results, a grain coarsening equation including the influence of current density is proposed, dn dn 0 1⁄4 Kjmt. The cur...

Thermoelectric effects which are responsible for the direct conversion of heat energy into electrical energy and vice versa have recently received renewed attention [1]. So far optimal thermoelectric response has been achieved in traditional doped semiconductors, but recent improvements in both the synthesis of correlated electron systems and the theoretical methods for treating them have gener...

The steady flow of a Reiner-Rivlin fluid with Joule heating and viscous dissipation is studied. We present a novel technique for accelerating the convergence of the spectral-homotopy analysis method. Solutions of the nonlinear momentum and energy equations are obtained using the improved spectral homotopy analysis method. Solutions were also generated using the spectral-homotopy analysis method...

The effects of velocity slip and Joule heating on peristaltic flow of MHD Newtonian fluid in a porous channel with elastic wall properties have been studied under the assumptions of longwavelength and low-Reynolds number. The analytical solution has been derived for the stream function, temperature and heat transfer coefficient. The emerging flow parameters on the velocity, temperature and heat...

Saturated-core fault current limiters (FCLs) are devices that have many applications and potential for use within power networks. At a commercial scale, these devices require high H-field magnets to saturate the steel core, which can typically only be achieved through the use of superconducting coils. Here, we present several challenges that arise in the application of superconducting coils in ...

This paper presents the methodology developed for the SOLARGIS project a Joule project for the integration of renewable forms of energy for dispersed electricity production. The aim is to demonstrate the efficiency of GIS (Geographical Information Systems) as a toll for development of integration plans for renewable forms of energy. We present the methodologies for: renewable resources for in a...
