Journal of International Economics, 2012 This paper examines why surges in capital flows to emerging market economies (EMEs) occur, and what determines the allocation of capital across countries during such surge episodes. We use two different methodologies to identify surges in EMEs over 1980-2009, differentiating between those mainly caused by changes in the country's external liabilities ...

Research on Online Diagnosis Method of Fuel Cell Centrifugal Air Compressor Surge Fault
Energies, 2021 Stable operation of fuel cell air compressions is constrained by rotating surge in low flowrate conditions. In this paper, a diagnosis criterion based on wavelet transform to solve the surge fault is proposed. First of all, the Fourier transform was used

Coastal Engineering Proceedings, 1950 Surge is the name applied to wave motion with period intermediate between that of ordinary wind waves and that of the tides; say from one to sixty minutes. An additional characteristic of surge is that it is usually of very low height; perhaps 0.3 ft. is typical.
