This paper proposes a low power EHC that performs synchronous energy conversion on a tri-plate variable capacitor to improve the maximum achievable power. A tri-plate macro electrostatic generator with capacitor variation of 405 pF to 1.15 nF and 405 pF to 1.07 nF on two complementary adjacent capacitors operating 180° out of phase at 98 Hz is fabricated and used in the characterization of the ...

Several factors interact in influencing aerosol deposition during mechanical ventilation. Among these factors, the artificial airway is a significant barrier for aerosol deposition. Earlier studies overemphasized the impediments created by the artificial airway to aerosol delivery, because the aerosol generator was placed adjacent to the endotracheal tube or was connected to it. When the aeroso...

In this research, a new technetium-99m generator has been developed with addition of Cerium oxide to alumina column.  The adsorption behaviors of 99Mo in the form of molybdate and 99mTc in the form of pertechnetate on CeO2/Al2O3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using Al2O3. Ceric ions were selected as an addit...

this paper provides a review on major ergodic features of semi-independent hyper mv {algebra dynamical systems. theorems are presentedto make contribution to calculate the entropy. particularly, it is proved that thetotal entropy of those semi-independent hyper mv {algebra dynamical systemsthat have a generator can be calculated with respect to their generator ratherthan considering all the par...

This paper presents an approach to calculate the equivalent stray capacitance (SC) of n-turn of the helical flux compression generator (HFCG) coil with multi layer conductor wire filaments (MLCWF) in the form of rectangular cross-section. This approach is based on vespiary regular hexagonal (VRH) model. In this method, wire filaments of the generator coil are separated into many very small simi...
