As the explosive growth of mobile networks, green mobile networks have been studied extensively. DLNA protocol, widely used in smart home, does not take any consideration for power saving. In this paper, we propose an energy-efficient mechanism for DLNA (E-DLNA), which can achieve balance between QoS provision and energy efficiency. The core network condition estimation algorithm TES used in E-...

Fracture is a highly dissipative process in which much of the stored elastic energy is consumed in the creation of new surfaces. Surprisingly, many plants use fracture to launch their seeds despite its seemingly prohibitive energy cost. Here we use Impatiens glandulifera as model case to study the impact of fracture on a plant's throwing capacity. I. glandulifera launches its seeds with speeds ...

Effective energy windows (Gamow windows) of astrophysical reaction rates for (p,γ), (p,n), (p,α), (α,γ), (α,n), (α,p), (n,γ), (n,p), and (n,α) on targets with 10 ≤ Z ≤ 83 from protonto neutrondripline are calculated using theoretical cross sections. It is shown that widely used approximation formulae for the relevant energy ranges are not valid for a large number of reactions relevant to hydros...

Mathematical modeling of heterogeneous high-energy explosives poses a vexing problem. These materials have a complex microstructure in which crystalline fragments of the energetic material are held together by an inert plastic binder, and voids and pores abound within the granular aggregate. It is observed that when a sample of such an explosive is subjected to a sufficiently strong stimulus, s...

A considerable amount of energy is released in the form of shock wave from explosive charge detonation. Shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. The rest of the shock wave energy is transferred to rock mass as ground vibration. Ground vibration is conveyed to the adjacent structures by body and surface waves. Geological structures li...

buildings play an important role in the energy demand sector. due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...

air pollution is an example of a negative externality; it imposes harmful effects and costs on people other than polluters. in controlling air pollution, efficiency argument implies that, there is a rolefor the government to play. studies show that taxation of fuels can be a powerful indirect instrumentfor controlling air polluticn because of the association between fuels use and emissions. in ...
