The AP1000 nuclear steam supply system (NSSS) is designed to accept large load rejections without initiating a reactor trip using the reactor power control system, the pressurizer pressure and water level control systems, the feedwater control system, the steam dump control system and the rapid power reduction (RPR) system.
Increasing demand for power reduction in computer systems has led to new trends in computations and computer design including reversible computing.
This leads to an overall power reduction in the communication system.
With this level of power reduction, the adaptive STFC MB-OFDM UWB system could be an energy-efficient alternative for high data rate WBAN applications.
Figures 10 and 11 show the simulation curves depicting BER performance and power reduction for the mentioned system with and without subcarrier selection based on pre-equalization at the transmitter for 2 and 32 users respectively.
Figures 5 and 6 show the simulation curves depicting BER performance and power reduction for the considered system with and without subcarrier selection based on post-equalization at the receiver for 2 and 32 users, respectively.
The latter behavior is also confirmed by the results presented in Figure 3d, where the percentage of overall system power reduction under PCC is up to 70%, with respect to the corresponding one under PC (i.e., from 55 to 17 W).
Although in certain scenarios a loss in system capacity is incurred by the system-wide power reduction (as (22) suggests), the guaranteed energy efficiency gain can compensate this deficit.
Recently, "lazy scheduling" has been proposed for system level power reduction.
Using this model, we show that our proposed statistical task scheduling algorithm can achieve substantial power reduction under different values of system constraints.
Recently, peak power reduction schemes, developed for single antenna systems, have been transferred to the MIMO case.
