A bidirectional AC-DC converter for charging piles with a backflow power optimization control strategy

Journal of Physics: Conference Series
Abstract This paper proposes a single-stage isolated converter with a backflow power optimization method for V2G charging piles. The modulation algorithm is optimized, and the phase shifts are designed to minimize the backflow power. Due to the suppression of backflow power during the switching period, the power factor correction (PFC ...

Quantum Monte Carlo study of a vortex in superfluid $^4$He and search for a vortex state in the solid

, 2014
We have performed a microscopic study of a straight quantized vortex line in three dimensions in condensed $^4$He at zero temperature using the Shadow Path Integral Ground State method and the fixed-phase approximation.

A Portable Multi‐Parameter Fluid Monitoring Unit for Real‐Time Measurements During Well Development and Geothermal Operations

Groundwater Monitoring &Remediation, EarlyView.
Abstract Monitoring of fluid parameters during well development, groundwater production, or geothermal operation is essential for the understanding of subsurface and well processes. We developed FluMoMax, a portable fluid monitoring unit, that can measure several physicochemical parameters in real‐time, to monitor fluid characteristics and to enable ...

The Milan Score is an Effective Manometric Tool to Predict Gastroesophageal Reflux in Patients With Laryngopharyngeal Symptoms

Neurogastroenterology &Motility, EarlyView.
Patients with isolated LPS demonstrated a lower likelihood of EGJ disruption, pathologic GERD, and abnormal Milan score. The Milan score performed similarly well in the identification of GERD in both LPS and typical symptoms. The Milan score could therefore be used as an upfront test in LPS patients.
