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...
Lightning strikes to overhead transmission lines cause travelling waves which propagate along the overhead line and enter substations where they cause overvoltages which can pose a risk to any items of equipment connected, such as cables or transformers. With the use of metal-oxide arresters, these overvoltages are reduced to values which, taking into account an adequate safety margin, are belo...
background: hospital surge capacity (hsc) is essential to the successful management of expected consequences of disasters and mass casualty incidents (mcis). in mcis, an unanticipated number of sick or injured people refer to the hospital, and thus, the hospital is faced with a significant increase in the burden of necessary activities and services. therefore, managing the process in order to m...
Morning blood pressure (BP) surge is reported as a risk factor for cardiovascular events and end-organ damage independent of the 24-h BP level. Controlling morning BP surge is therefore important to help prevent onset of cardiovascular disease. We compared the efficacy of azilsartan and candesartan in controlling morning systolic BP (SBP) surges by analyzing relevant ambulatory BP monitoring da...
