Experimental results demonstrate that the optimized energy consumption of WSN, as well as energy harvesting of at least 1 mW (0 dBm) from ambient RF signal, ensure the 'perpetual' operation of WSN.
After obtaining the annual energy saving conferred by the measure (calculated via the difference between original and optimized consumptions and extrapolated for 1 year of homogeneous activity), payback time for the investment was estimated using Eq. 15.
The process was optimized with reasonable consumption of coagulant and quantity of obtained sludge.
On Huawei Mate 7 smartphone (i.e., 1.8GHz Kirin 925 CPU), the practical running time, storage, and memory consumption of optimized AlexNet is 0.95s, 12.60MB, and 74.65MB respectively.
Results showed that: control factors of X1, X2 and X3 are significant at 0.1% probability level by F test of analysis of variance (ANOVA), with orders of importance as X1, X2 and X3; optimized parameters of the rotary blade are X1 30°, X2 52°, and X3 120°; power consumption of the optimized rotary blade is 0.161 kW, with a 12.40% of power consumption reduction compared with the traditional design.
The simulation result shows that the overall energy consumption of the optimized fluid network has a decrease obviously.
Energy consumption of the optimized MC conditions was lower than the conventional process (4.67 kWh vs 6.52 kWh) and the cooking time was decreased by 56% compared to TC.
Confirmatory experiments carried out in these optimized conditions resulted in specific energy consumption of 10.72 kW h/t and size reduction index of 3.91 thus corroborating the validity of the response surface models.
Compared with actual operating scheme, the total air volumes of optimized schemes decrease 2.4%, total power consumption of cooling fans decreases 61.1% and the outlet temperature of clinker decreases 122.9 °C which shows a remarkable energy-saving effect on energy consumption.
For new generation BSs and future developments where the power consumption of the components is optimized, new measurements will be necessary.
