Data analysis has been one of the core activities in scientific research, but limited by the
availability of analysis methods in the past, data analysis was often relegated to data …

Emotion can be defined as a voluntary or involuntary reaction to external factors. People
express their emotions through actions, such as words, sounds, facial expressions, and …

In the marine environment, many fields have fluctuations over a large range of different
spatial and temporal scales. These quantities can be nonlinear and non-stationary, and …

In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-
order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series …

Time series of historical annual average temperature, total precipitation, and extreme
weather indices were constructed and analyzed for 103 (for temperature indices) and 115 …

Multi-scale systems, involving complex interacting processes that occur over a range of
temporal and spatial scales, are present in a broad range of disciplines. Several …

Increasing sea level rise will lead to more instances of nuisance flooding along the Virginia
coastline in the coming decades, causing road closures and deteriorating infrastructure …

Abstract Hilbert-Huang Transform (HHT) is a data analysis tool, first developed in 1998,
which can be used to extract the periodic components embedded within oscillatory data …

The objectives are to study and model the aggregate wind power fluctuations dynamics in
the multifractal framework. We present here the analysis of aggregate power output sampled …

This article focuses on the image fusion of high-resolution panchromatic and multispectral
images. We propose a new image fusion method based on a Hue-Saturation-Value (HSV) …
