1Spectral modelling synthesis — Spectral Modeling Synthesis or simply SMS is an Acousic 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 …
2Spectral density — In statistical signal processing and physics, the spectral density, power spectral density (PSD), or energy spectral density (ESD), is a positive real function of a frequency variable associated with a stationary stochastic process, or a… …
3Global climate model — AGCM redirects here. For Italian competition regulator, see Autorità Garante della Concorrenza e del Mercato. Climate models are systems of differential equations based on the basic laws of physics, fluid motion, and chemistry. To “run” a model,… …
4Discrete cosine transform — A discrete cosine transform (DCT) expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, from lossy… …
5Wind wave model — NOAA Wavewatch III 120 hour Forecast for the North Atlantic In fluid dynamics, wind wave modeling describes the effort to depict the sea state and predict the evolution of the energy of wind waves using numerical techniques. These simulations… …
6A derivation of the discrete Fourier transform — In mathematics, computer science, and electrical engineering, the discrete Fourier transform (DFT), occasionally called the finite Fourier transform, is a transform for Fourier analysis of finite domain discrete time signals. As with most Fourier …
7Tropical cyclone forecast model — [ National Hurricane Center (NHC)] A tropical cyclone forecast model is a computer program that uses meteorological data to forecast the motion and intensity of tropical cyclones. Such models utilize powerful supercomputers with sophisticated… …
8Inverse scattering transform — In mathematics, the inverse scattering transform is a method for solving some non linear partial differential equations. It is one of the most important developments in mathematical physics in the past 40 years. The method is a non linear… …
9HF Spectral Occupancy Experiment — The HF Spectral Occupancy Experiment is a programme of research undertaken by the Digital Communications Department at University of Manchester Institute of Science and Technology to measure and analyse the usage of the high frequency (HF)… …
10Integrable system — In mathematics and physics, there are various distinct notions that are referred to under the name of integrable systems. In the general theory of differential systems, there is Frobenius integrability, which refers to overdetermined systems. In… …
