Optimal allocation of UPFC based on healthy and stressed zones for critical power systems

open access: yesEngineering Science and Technology, an International Journal, 2023
A unified power flow controller (UPFC) is a versatile compensator providing multi-variable control for the critical power systems (CPS). In an attempt to reduce the search space for optimal allocation of UPFC thereby standardizing the deliberation over ...

Application of hydraulic flow units’ approach for improving reservoir characterization and predicting permeability

open access: yesJournal of Petroleum Exploration and Production Technology, 2019
It is highly essential to characterize the reservoir accurately as possible to implement enhanced oil recovery and development scenarios. Determining complex variations in pore geometry aids in identifying rock types with similar fluid flow properties ...

Impact of Scribes with Flow Coordination Duties on Throughput in an Academic Emergency Department

open access: yesWestern Journal of Emergency Medicine, 2020
Introduction: With the increasing influence of electronic health records in emergency medicine came concerns of decreasing operational efficiencies. Particularly worrisome was increasing patient length of stay (LOS). Medical scribes were identified to be

Synchrotron Self-Compton Model for Rapid Nonthermal Flares in Blazars with Frequency-Dependent Time Lags [PDF]

open access: yes, 2004
We model rapid variability of multifrequency emission from blazars occurring across the electromagnetic spectrum (from radio to gamma-rays). Lower energy emission is produced by the synchrotron mechanism, whereas higher energy emission is due to inverse ...

Litho-stratigraphic characterization of hydrogeological and hydraulic flow units via electrical resistivity, Stratigraphic Modified Lorenz Plots, and flow zone indicator models

open access: yesSolid Earth Sciences
Litho-stratigraphic characterization within hydrogeological units of a major aquifer system in Southern Nigeria was carried out using Electrical Resistivity (ER), Stratigraphic Modified Lorenz Plots (SMLP), and Flow Zone Indicator (FZI) algorithms.
