MOTIVATION Mass spectrometry is a high throughput, fast, and accurate method of protein analysis. Using the peaks detected in spectra, we can compare a normal group with a disease group. However, the spectrum is complicated by scale shifting and is also full of noise. Such shifting makes the spectra non-stationary and need to align before comparison. Consequently, the preprocessing of the mass ...

The Empirical Mode Decomposition is a process for signals which produces Intrinsic Mode Functions from which instantaneous frequencies may be extracted by simple application of the Hilbert transform. The beauty of this method to generate redundant representations is in its simplicity and its effectiveness. Our study has two objectives: first, to provide an alternate characterization of the Intr...

In this paper, we propose a variant of the Empirical Mode Decomposition method to decompose multiscale data into their intrinsic mode functions. Under the assumption that the multiscale data satisfy certain scale separation property, we show that the proposed method can extract the intrinsic mode functions accurately and uniquely.

Sea-level rise (SLR) has become an essential global environmental problem and great importance is attached by all sectors of society. This study aims to estimate the trends SLR from tide-gauge measurements located in different sites Taiwan. Different methods analysis, such as linear-regression method (LRM), Hilbert–Huang transform (HHT), modified harmonic analysis (MHA) are used their applicabi...

This study considers the impact of extreme climates on most world’s land and seas, which may cause average sea level to rise due global climate change. Affected by level, it will change distribution characteristics tides, waves currents. When currents in area changes, changes overall environmental estuary coastal areas, further affects function protection facilities. takes Yilan as an example, ...
