ABSTRACT

Recently a new spectral technique has been developed for the analysis of aperiodic signals from nonlinear systems-the Hilbert-Huang transform. It is shown how this transform can be used to discover synoptic and climatic features: For sea level data, the transforms capture the oceanic tides as well as variations in precipitation patterns. In the case of solar radiation, variations in the diurnal and seasonal cycles are observed. Finally, from barographic data, the Hilbert-Huang...

What is Fourier Transform?
Instrument Business Outlook ; What is Fourier Transform? A Fourier series is a mathematical tool for studying wave phenomena, particularly in relation to time. Fourier transform (FT) is a method of taking data on wave forms and analyzing it to determine the nature of the waves and their sources. In relation to analytical
Computer Vision-Aided Fabric Inspection System for On-Circular Knitting Machine
Textile Research Journal ; ABSTRACT This paper describes a computer vision-based fabric inspection system implemented on a circular knitting machine to inspect the fabric under construction. The study consisted of two parts. In the first part, detection of defects in knitted fabric was performed and the performance of three
Rapid determination of tetracycline in milk by FT-MIR and FT-NIR spectroscopy
Journal of Dairy Science ; ABSTRACT The feasibility of measuring tetracycline at the ppb levels in milk was investigated by Fourier transform mid-infrared (FT-MIR) and Fourier transform near-infrared (FT-NIR) spectroscopic techniques. Milk samples spiked with different concentrations of tetracycline were scanned using FT-MIR
Optical Methods in Experimental Mechanics
Experimental Techniques ; OPTICAL METHODS Back to Basics Part 15: Fourier Optical Processing REVIEW AND PURPOSE Article 14 of this series demonstrated an example of the optical Fourier transform, and it also uncovered a major problem with the Fraunhoffer limitation in that the transform is located far away from the
Digging through the noise in the S&P 500.
Futures (Cedar Falls, Iowa) ; Using the discrete fourier transform to analyze the markets is not for the mathematically faint of heart. But if care and effort are put into the application of this technique, your discrete analysis can lead to some rather absurd profits. Noise is the bane of many market analysts. If only we could
History of fourier transform-infrared spectroscopy
Spectroscopy ; Spectroscopy using interferometric methods dates back to the late l9th century. This very active scientific period has been called the golden age of creativity. Many scientific giants, including Albert A. Michelson, who is credited with developing the first operable interferometer, were
Application of the Fourier transform in antenna pattern measurements.
Microwave Journal ; The Fourier transform of an antenna radiation pattern is the aperture space distribution across the antenna. The transform from a single pattern results in a collapsed distribution and, therefore, is most useful for antennas that are physically long and arrayed in one dimension (typical
C program magnifies spectrum when an FFT can't hack it.(Innovative Designs from Readers; Fast Fourier Transform)
Electronic Design ; Many science and engineering applications require an accurate frequency spectrum or Fourier transform of a signal. The Fourier transform of a sequence of samples of a signal is shown in Equation 1. (1) [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] This equation is written in dimensionless
Structural changes in bacteriorhodopsin during the photocycle measured by time-resolved polarized fourier transform infrared spectroscopy
Biophysical Journal ; ABSTRACT The structural changes in bacteriorhodopsin during the photocycle are investigated. Time resolved polarized infrared spectroscopy in combination with photoselection is used to determine the orientation and motion of certain structural units of the molecule: Asp-85, Asp-96, Asp-1 15, the
