a watershed management program is usually based on the results of watershed modeling. accurate modeling results are decided by the appropriate parameters and input data. precipitation is the most important input for watershed modeling. precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. therefore, properly describing the spatial variation o...

For a non-stationary seismic signal, time–frequency analysis methods often include time window function that serves as weighting and by which the signal is multiplied to form segment. The has highest coefficient for central sample of rest segment, there no adequate representation in frequency spectrum. Here, I propose use multiple orthogonal functions properly represent local spectral property ...

We present a novel approach to image segmentation using iterated Graph Cuts based on multi-scale smoothing. We compute the prior probability obtained by the likelihood from a color histogram and a distance transform using the segmentation results from graph cuts in the previous process, and set the probability as the t-link of the graph for the next process. The proposed method can segment the ...

The wave packet molecular dynamics (WPMD) method provides a variational approximation to the solution of the time-dependent Schrödinger equation. Its application in the field of high-temperature dense plasmas has yielded diverging electron width (spreading), which results in diminishing electron-nuclear interactions. Electron spreading has previously been ascribed to a shortcoming of the WPMD m...

In this paper, a novel technique for detection of healthy (H), myopathy, (M) and amyotrophic lateral sclerosis (ALS) electromyography (EMG) signals is proposed employing robust hyperbolic Stockwell transform (HST). HST an efficient signal processing to analyze any nonstationary in joint time–frequency (T–F) plane. However, major issue with the optimum selection Gaussian window parameters since ...

ABSTRACT The late-time effect of primordial non-Gaussianity offers a window into the physics inflation and very early Universe. In this work, we study consequences particular class that is fully characterized by initial density fluctuations drawn from non-Gaussian probability function, rather than construction form for bispectrum. We numerically generate multiple realizations cosmological struc...

The Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Earth Observing System satellites Terra and Aqua include infrared bands that are designed for the accurate measurement of sea-surface temperature (SST). In addition to the conventional ‘split-window’ bands in the 10-12 μm atmospheric window (similar in spectral properties to the corresponding channels of the heritage instrume...
