With zero circuit power, the energy efficiency achieves its maximum value as the spectral efficiency approaches zero.
However, a balance between network function performance and energy efficiency achieved through virtualization has to be resolved.
For example, the energy efficiency achieved through ' just-in-time sensing otherwise sleeping' behavior of sonars introduces latency and possible missouts.
Both approaches exploit information at routing layer in order to deliver data packets much faster, without sacrificing the energy efficiency achieved by the duty-cycle mechanism.
While in the high transmit power region, it is observed that the energy efficiency achieved by EEMax (Aware/Ignorant) is better than that of SRMax (Aware/Ignorant).
Let Z denotes the set of a solution to Problem P8 and f Z denotes the energy efficiency achieved by using the set Z. Thus, the set of the optimal solution is given by Z ∗ = arg max Z f Z.
Methane conversion largely exceeded over equilibrium conversion rate, whereas product selectivity tended to follow equilibrium composition at given temperature: energy cost and energy efficiency achieved 134 MJ/kg H2 and 69%, respectively.
Synergistic effect between barrier discharge and Ni/SiO2 catalyst was clearly observed when bed temperature exceeded 400 °C, energy cost and energy efficiency achieved 134 MJ/kg H2 and 26%, respectively.
Some simulation results comparing the proposed control architecture with other strategies studied in the literature are included, regarding the energy efficiency achieved in steady state and the dynamic behaviour of the controlled variables, where the controllability issues are highlighted.
On the other hand, these Guidelines provide the institutions responsible for protecting the building, the possibility to objectively decide on the level of energy efficiency achieved as a result of the rehabilitation in accordance with the conservation criteria.
