This article reviews what is known about daily emergency department (ED) surge and ED surge capacity and illustrates its potential relevance during a catastrophic event. Daily ED surge is a sudden increase in the demand for ED services. There is no well-accepted, objective measure of daily ED surge. The authors propose that daily and catastrophic ED surge can be measured by the magnitude of the...

The compressor system is widely used in aerospace, chemical industry, and other industrial fields. Modeling a of great significance to the study hydrodynamics surge characteristics. Modular Dynamic System Greitzer (MDSG) modeling real-time model simulate dynamic response complex systems. An air suction parallel with three compressors modeled simulated by MDSG model, results are compared experim...

quadricuspid aortic valve (qav) is an uncommon congenital anomaly which was an incidental finding during surgery or autopsy in the past. we present the case of a 44-year-old woman with moderately severe aortic regurgitation due to unequal cusp size qav diagnosed via transesophageal echocardiography. due to echocardiographic imaging improvement, the diagnosis of qav is now easier and earlier tha...

This paper aims to measure and analyze of the leakage current of 20 kV polymer and porcelain metal oxide surge arresters under humid ambient conditions by applying different voltages to the arresters terminal. The characteristics of the leakage currents at that stage have been investigated when changes in the ambient humidity were introduced in an artificial fog chamber. It is assumed that magn...

Eye contact captures attention and receives prioritized visual processing. Here we asked whether eye contact might be processed outside conscious awareness. Faces with direct and averted gaze were rendered invisible using interocular suppression. In two experiments we found that faces with direct gaze overcame such suppression more rapidly than faces with averted gaze. Control experiments ruled...

The objective of this paper is to present the modeling and analysis of a 1.7 Mva SMES-based voltage sag corrector devices. The topology of the SMES-based system and its response to an upstream fault are described. This paper details various modeling aspects of the device including methods to generate a triangular signal and an internal reference voltage. Models to characterize the harmonic cont...

This paper briefly summarizes that during the depressurization operation in subsea pipeline for maintenance or prevention of hydrate formation, because flare knock-out drum pump is designed ambient temperature, and cannot deal with low temperature fluid process. Therefore, needs to be heated meet requirement pump. In order avoid volume exceeding surge drum, concept multi stage innovatively prop...

In this paper, a novel active control approach is designed for surge instability in the compressor system using finite-time fuzzy sliding mode scheme. The primary novelty of study lies development presence disturbance and uncertainty characteristic curve also throttle valve. To ensure stability closed-loop Lyapunov's concept, finite time method proposed based on estimation robust adaptive metho...
