Abstract: In this work, the reverse dispersion entropy (RDE) is used to process the squared envelope (SE) signal in order to detect nonstationarites. Based on the idea of spectral kurtosis (SK) and kurtogram, the squared envelope ...

Abstract: The feasibility of small and medium dams in arid environments is studied. A novel method for prioritization of dam commissioning is proposed. The method focuses on key hydrologic and economic factors that affect the ...

Abstract: A model for the water retention behavior of unsaturated granular soil is developed by extending the classic bundled cylindrical capillary representation of pore space to a geometry more closely approximating that of granular ...

Abstract: An approach is presented for predicting saturated hydraulic conductivity (

Abstract: Laboratory fall cone penetration is measured as a function of saturation for four sands using equipment more commonly used to quantify plasticity and undrained strength of fine-grained soils. Relations between penetration ...

Abstract: Rainfall-runoff conceptual models are used largely for river discharge prediction, for waterworks design, and as support for water quality assessment. The generalized split-sample test (GSST) recently was recommended to ...

Abstract: Reference evapotranspiration (ETo) estimates in greenhouses require the measurement of several meteorological variables. These measurements are not always conducted by water managers. The ETo estimates also depend on the ...

Abstract: Estimations of Penman-Monteith reference evapotranspiration (EToPM) in greenhouses can benefit the operation of these intensive agricultural production systems. Meteorological variables required to calculate EToPM within ...

Abstract: The nonorthogonal basis generalized Fourier transform is used as orders extraction technique during machinery speedup and slowdown tests due to nonstationary nature of vibration signals in these tests. The kernels of this ...
