Detection of delay time between the alterations of cardiac rhythm and periodic breathing
Figliola, A.; Rosso, O.A.; Serrano, E. - In: Physica A: Statistical Mechanics and its Applications 327 (2003) 1, pp. 174-179
Analysis of time-series multichannel physiological data were performed using wavelets. Wavelet provides a time-scale description and lead us to decompose any signal into frequency bands. A better precision in the frequency domain is often necessary to detect stationary phenomena or characterize...

Measuring Aid Flows: A New Approach
Chang, Charles C.; Fernández-Arias, Eduardo; Servén, Luis - Inter-American Development Bank - 1998
The debate on the effectiveness of foreign aid has intensified in recent years as aid has come under increasing budgetary pressures in donor countries. Whatever the merits of the opposing arguments, the fundamental issue arises of whether conventionally-used measures of aid such as ODA, which...
