TDAT-time domain analysis tool for EEG analysis
IEEE Transactions on Biomedical Engineering, 1990An interactive design and analysis tool for displaying and quantifying multiple channels of data is presented. The system allows one to easily visualize multiple data channels and simultaneously observe the effects of filters on the data and to evaluate signal detection algorithms.

Cost analysis in the time domain
European Journal of Operational Research, 1993Abstract Government cost analysts must often construct models using production data that are limited by a contract between the producer and the government. The producer usually does not share cost data with the government unless the contract requires that data are reported.

Time-Domain Structural Analysis of Speech
2003This paper deals with an auxiliary speech signal parametrisation method based on structural analysis of speech signal in time domain. The method called TIDOSA (TIme-DOmain Structural Analysis) grounds in analysing the "shape" of incoming waveform peaks. The whole input acoustic signal is transformed into a sequence of peak shape class indices.

This chapter describes numerical integration methods for transient stability analysis. Section 8.1 provides a qualitative justification of the need for numerical integration and describes intrinsic limitations of Lyapunov’s direct method. Section 8.2 describes two common models for time domain analysis, namely the current-injection and the power ...

Proceedings of the IEEE, 1970
Time-domain ray analysis is employed in a novel way to explain impulse response waveforms. Examples of reflection from a disk, corner, and paraboloid are discussed and supported by experimental results. It is shown that the reflected waveforms can be readily characterized by superpositions in time of direct, specular, and diffracted rays.

In the frequency domain discussed in the previous chapter, a spectral approximation is used for an arbitrary second-order stationary time series ..., y -1, y 0, y 1,.... In the traditional approach, the variance components in the spectral approximation will be nonzero, thus there is little chance of developing a parsimonious model.

IEEE Computer Applications in Power, 1992
The program Power Electronic Circuit Analysis (PECAN), which has been made to handle some power engineering applications not suited for SPICE or EMTP, is discussed. Time functions of voltages, currents, torque, angular speed, power, and other derived quantities can be calculated and plotted on the screen a printer, or a plotter.

Time-Domain Analysis of the Electrocardiogram
2019The electrocardiogram (ECG) is an affordable and well-studied biosignal, which has a wide presence in clinical research and practice, especially as a frontline diagnostic tool that measures the evolution of the electrical activity of the heart, with characteristic morphologies for atrial and ventricular activity, depending also on the position of ...

Time Domain to Frequency Domain: Spectrum Analysis
2014The concept of spectrum can be attributed to Isaac Newton, who, with the aid of a prism, discovered that sunlight can be decomposed into a spectrum of colors from red to violet in about 1700. This indicates that any light comprises numerous components of light of various colors (wave lengths).
