Smart inverters are studied in both the dynamic/transient and steady state in a simulation environment. Using EPRI OpenDSS, five real California feeders are simulated over a 95 day period while the PV penetration and smart inverter fraction are varied. From the simulations, it is shown that smart inverters operating under different Volt/VAr based control schemes improve feeder conditions. The i...

The superconducting (SC) coils of the Divertor Tokamak Test (DTT) facility will be connected to current leads by a set SC feeders, currently designed as cable-in-conduit conductors wound using commercial NbTi strands cooled Supercritical Helium at 4.5 K. feeders are immersed in magnetic field generated coil and plasma outside magnet system, so that maximum on most loaded feeder can reach 4 T fu...

The power quality issues in the world today are critical to development of different nations. Prosperity each nation depends on availability constant supply and is very important required developments past, present future. Constant a major challenge Africa particularly Nigeria where generated less than thirty percent power. metrics voltage sag, flickers, spikes, harmonics, notching, transients ...

Programmable vector elds are an abstraction to represent a new class of devices for distributed, non-prehensile manipulation for applications in parts feeding, sorting, positioning, and assembly. Unlike robot grippers, conveyor belts, or vibratory bowl feeders, these devices generate force vector elds in which the parts move until they may reach a stable equilibrium pose. Recent research in the...

The deep-sea benthic community at the Porcupine Abyssal Plain (NE Atlantic) is a highly food limited system. The annual input of sedimenting phytodetritus, which reaches the sea floor around May/June, is the major input of energy. The relative trophic position of the most abundant components of the benthos (90 species or higher taxonomic groups), including meiofaunal, macrofaunal, and megafauna...

We review the origins, prominent innovations, and major patterns of diversification in suction feeding by vertebrates. Non-vertebrate chordates and larval lamprey suspension-feed by capturing small particles in pharyngeal mucous. In most of these lineages the gentle flows that transport particles are generated by buccal cilia, although larval lamprey and thaliacean urochordates have independent...
