Fourier analysis of the echocardiogram [PDF]
Physics in Medicine & Biology, 1978 Fourier analysis has been applied to the analysis of echocardiograms, with the result that anterior mitral leaflet waveforms have been classified in a manner which is unambiguous and which lends itself easily to present-day automated technology.

Publisher Summary Truly aperiodic functions do not exist. Infinite limits are too far away to be reached in practice, and negative frequencies do not exist. Zero means negligible, or impossible to pick out of the ubiquitous noise, simply not important enough to be considered.

Fourier Analysis and Fourier Transform
2017The origins of Fourier analysis in science can be found in Ptolemy’s decomposing celestial orbits into cycles and epicycles and Pythagoras’ decomposing music into consonances. Its modern history began with the eighteenth century work of Bernoulli, Euler, and Gauss on what later came to be known as Fourier series. J.

Fourier Analysis of Cephalometric Shapes
The Cleft Palate-Craniofacial Journal, 1996Craniofacial growth and development involve both size and shape variations. Shape variations can be assessed independently from size using mathematical methods such as the Fourier series. A method for the reconstruction of outlines starting from selected landmarks and for their Fourier analysis has been developed and applied to analyze the age ...

Publisher Summary One of the most remarkable results in mathematics is the discovery by Fourier that any reasonably well-behaved function f (x) can be represented as the sum of a (possibly infinite) set of sine and cosine functions. This discovery has had major theoretical and practical applications throughout mathematics and physical science.

Publisher Summary This chapter discusses Fourier analysis and associated transform methods for both discrete-time and continuous-time signals and system. Fourier methods are based on using real or complex sinusoids as basic functions, and they allow signals to be represented in terms of sums of sinusoidal components. In order for a digital computer to

Fat Diagonals and Fourier Analysis
SIAM Journal on Matrix Analysis and Applications, 2003The authors use methods from Fourier analysis and from the theory of Toeplitz matrices to study the effect on norms of matrices obtained by various truncations. Examples include the truncation of a matrix to a central band of diagonals, truncation to the off-diagonal part, and the upper triangular truncation. Using Fourier analysis, \textit{R. Bhatia} [
