Robust control of a two-terminal cryogenic current comparator
(Institute of Electrical and Electronics Engineers, 2013-06)
A digital H controller for a two-terminal cryogenic current comparator is designed. To this end, a set of mathematical models covering the actual system is proposed. Simulation results compare the open-and closed-loop ...
Direct Measurements of the Malvinas Current Velocity Structure
(Blackwell Publishing, 2021-03)
Direct velocity measurements of the Malvinas Current (MC) were carried out on multiple occupations of five transects across the flow using a Shipborne Acoustic Current Profiler (SADCP) on the R/V Akademik Sergey Vavilov ...
Current Ripple Amplitude Measurement in Multiphase Power Converters
(Institute of Electrical and Electronics Engineers, 2017-09)
Improvements in the total current ripple in interleaved power converters are mainly determined by differences between the phase inductor values. Several methods have been presented in the literature to mitigate this problem, ...
Crystallographic Texture Study of Nano-SiC-Doped MgB2 Wires
(Institute of Electrical and Electronics Engineers, 2021-08)
In this work, we present the characterization of Ti sheathed MgB2 wires prepared by PIT with two different cross-sections: circular and hexagonal. We determined the crystallographic texture of both the Ti sheath and the ...
Tidal and residual currents observations at the San Matías and San José Gulfs, Northern Patagonia, Argentina
(Coastal Education & Research Foundation, 2009-07-01)
Four current time series, collected at costal locations of the San Matías and San Jose' gulfs, Argentina, are analyzed for tidal and residual currents. Tides dominate San Matías Gulf dynamics, accounting for more than 72% ...
Availability of urinary albumin measurement in Southern Brazilian laboratories
Julia radar studies of electric fields in the equatorial electrojet
(American Geophysical Union, 1997-07)
First results from the JULIA radar at Jicamarca are presented. These include coherent scatter observations of the equatorial electrojet and of 150-km echoes. Interferometry is used to measure the zonal drift rate of kilometer ...
Power transformers monitoring based on electrical measurements: State of the art
(Institution of Engineering and Technology, 2018-07-10)
Faults diagnosis in power transformers has been traditionally based on the insulation resistance measurement, polarisation index, analysis of dissolved gasses in oil, dissipation/power factor measurement, and partial ...
Effectiveness measurement: when will we get it right?
(Universidad ESAN. ESAN EdicionesPE, 2009-12-30)
Credible demonstration of policy or program impacts depends on understanding the distinction between inputs outputs outcomes and indicators. Moreover in order to be trusted public reports on a programs' performance need ...
