The effect of H2 purity on the combustion, performance, emissions and energy costs in an SI engine
This paper aims to examine the effect of hydrogen purity on the combustion, performance, NOx emissions and energy costs in a spark ignition engine. In accordance with this purpose, two commercial hydrogen gases of different purity (i. e.

Energy efficiency vs. economic cost of cellular networks under co-channel interference [PDF]
In this paper we analyze the efficiency of cellular network designs, by taking into account the co-channel interference among cells, different amounts of available bandwidths, and frequency reuse. A realistic power consumption model is considered for the

Which firms benefit from investments in green energy technologies? – The effect of energy costs
Firms will invest in green energy technologies only if these investments have an economic pay-off. Based on unique firm-level data from Austria, Germany, and Switzerland, we find that the marginal effect of investments in green energy technologies on ...

Cryptographic Energy Costs are Assumable in Ad Hoc Networks [PDF]
Performance of symmetric and asymmetric cryptography algorithms in small devices is presented. Both temporal and energy costs are measured and compared with the basic functional costs of a device. We demonstrate that cryptographic power costs are not
