Energy conservation is an important consideration in wave scattering and transmission from random rough surfaces and is particularly important in passive microwave remote sensing. In this paper, we study energy conservation in scattering from layered random rough surfaces using the second order small perturbation method (SPM2). SPM2 includes both first order incoherent scattering and a second o...

Classic Cartesian staggered mesh schemes have a number of attractive properties. They do not display spurious pressure modes and they have been shown to locally conserve, mass, momentum, kinetic energy, and circulation to machine precision. Recently, a number of generalizations of the staggered mesh approach have been proposed for unstructured (triangular or tetrahedral) meshes. These unstructu...

One of the important issue in MANETs is an energy saving and security. Each node in MANETs has limited energy resource, so that the lifetime of the network is one of the major critical issues. This paper studied SVM data aggregation method for classifying nodes according to their threshold values, this method eliminated the data redundancy and outliers but classification method is not much enou...

The proliferation of wireless services and anytime anywhere communication providing always-on connectivity, mobile devices are getting smaller and smarter. Therefore, third-generation (3G) wireless standards IEEE 802.16e should provide very efficient energy conservation mechanisms to achieve longer battery life while providing enhanced user experience and quality of service (QoS). The emerging ...

Energy conservation and CO2 abatement is currently an important development strategy for China. It is significant to analyze how to reduce energy consumption and CO2 emissions in China’s energy-intensive machinery industry. We not only employ a cointegration method and scenario analysis to predict the future energy demand and CO2 emissions in China’s machinery industry, but we also use the Mont...
