Spectral modeling synthesis (SMS) is an acoustic modeling approach for speech and other signals. SMS considers sounds as a combination of harmonic content and noise content. Harmonic components are identified based on peaks in the frequency spectrum of the signal, normally as found by the short-time Fourier signal that remains following removal of the spectral components.

SPECTRAL ANALYSIS OF DATA GENERATED BY SIMULATION EXPERIMENTS WITH ECONOMETRIC MODELS' BY THOMAS H. NAYLOR, KENNETH WERTZ, AND THOMAS H. WONNACOTT2 This paper is concerned with the use of spectral analysis to analyze data generated by com- puter simulation experiments with models of economic systems. An example model serves. PhenologyMMS is a simulation model that outlines and quantifies the developmental sequence of different crops under varying levels of water deficits, provides developmental information relevant to each crop, and is intended to be used either independently or inserted into existing crop growth models.

Global Hyperspectral Imaging Spectral-library of Agricultural Crops (GHISA) is a comprehensive collection and collation of a wide range of agricultural crop and vegetation hyperspectral data of agricultural crops, vegetation type, species, their growth stages, and their growing conditions. GHISA is developed by linking the hyperspectral signatures to: 1. precise geographic locations, providing .
