This paper studies the smart control issue for large power systems to effectively solve the problems of security, stability, and economical efficiency. A control scheme called as hierarchical hybrid control is proposed versus the hierarchical structure and hybrid dynamics of large power systems.A novel hybridmodel is first founded to clearly explain the interactive hybrid behaviors of the powe…
Abstract. The natural resonance appears at 16 GHz for (Fe, Ni)/C nanocapsules with (Fe, Ni) alloys as cores and graphite as shells. Reflection loss (RL) exceeding 10 dB was obtained in the whole Ku-band (12.4–18 GHz) for an absorber thickness of 2.0 mm, while it exceeds 20 dB over the 13.6–16.6 GHz range. In addition, the bandwidth does not change dramatically for the thicknesses of …
Abstract: This study examines in situ phosphorus treatment using a combined unit operation and process, a volumetric clarifying filter VCF. Urban rainfall-runoff transports phosphorus in dissolved and particulate phases with the latter phase distributed across the particulate matter PM gradation. From a clean initial condition, the VCF was monitored across 19 events without maintenance, t…
Abstract: As a unit operation, filtration generally requires flow equalization and primary clarification. This study examines the separation of runoff particulate matter (PM) in a volumetric clarifying filter (VCF). The VCF is a detention/retention vault integrating filtration after sedimentation. A paved source area (1,088 m2) directly loaded the vault (4.2 m3) with five radial filte…
