The battery energy storage systems (BESSs) have been increasingly installed in the power system, especially with the growing penetration rate of the renewable energy sources. However, it is difficult for BESSs to be profitable due to high capital costs. In order to boost the economic value of BESSs, this paper proposes a hierarchical energy management system (HiEMS) to aggregate multiple BESSs, and...
A novel ellipse cavity-backed and slot-tuned bow-tie antenna was designed to facilitate the application of ultra-wide band (UWB) ground penetrating radar (GPR) in low frequency. Lumped resistor loading was applied at the end of antenna arms to broaden the impedance bandwidth. Taper tuned method was also used to optimize the current distribution. Antenna characteristic was analyzed by simulation. Finally,...
Binary numbers (BNs) generation is crucial for wireless body sensor networks (WBSNs) security because they can be utilized for authentication or encryption of physiological data in WBSNs for healthcare applications. The paper compared pseudorandom number generators and biometrics based binary number generators for WBSNs, i.e. generated from the linear congruential generator (LCG) and the interpulse...
We have recently proposed a novel CO index, namely pulse time reflection ratio (PTRR), which is extracted from photoplethysmogram and electrocardiogram and measurable from wearable devices, and proved that this index is potentially useful for dynamic CO monitoring in a preliminary study carried out on young, healthy subjects. In this study, we presented an evaluation of this technique against impedance...
Taking the Nonghua 5 peanut as experimental material, the effects of low energy C+ ion (LECI) implantation in four doses on budding rate and other characters in the seedling stage of M1 generation and drought resistance of M3 generation were experimentally studied. The results showed that the ion took little affects on the budding rate and the germination potential, but tended to depress them. The...
