An enhanced strip theory, basically like that described in the last chapter, has been developed and used extensively over recent years for the analysis of planing boat performance and in designing planing power boats. The mechanics of this book now shifts, by both necessity and availability, from semi-analytical to more semi-numerically predicted boat ...

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.

Robust time-domain frequency analysis
SPIE Proceedings, 1992One domain in which the ordering filters have not appeared is frequency analysis. Simultaneously one must note that the impulse rejection properties of the ordering filters could be very beneficial due to the lack of robustness of the DFT/FFT. Another problem with the DFT/FFT is the ambiguity of the estimate of frequency at a point (frequency ...

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.

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 ...

LLC Resonant Converter-Frequency Domain Analysis or Time Domain Analysis
2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia), 2020Frequency domain based analysis methods have been widely used for resonant converters due to its simplicity and acceptable accuracy. However, considerable errors would exist when the switching frequency is far away from the resonant frequency, where the circuit currents contain rich harmonics, which cannot simply be neglected.

Optimizing Time-Domain Network Analysis
46th ARFTG Conference Digest, 1995In this work, we demonstrate how changes in sample density, time-window size, and waveform averaging affect the accuracy and acquisition time of calibrated time-domain network analysis. One of the key results from this study is that accuracy can be enhanced by eliminating the incident step-edge signal from the time-domain reflection waveform before ...

Accurate time-domain semisymbolic analysis
2010 XIth International Workshop on Symbolic and Numerical Methods, Modeling and Applications to Circuit Design (SM2ACD), 2010The paper deals with a method for accurate semisymbolic time-domain analysis of highly idealized linear lumped circuits. Pulse and step responses can be computed by means of the partial fraction decomposition. The procedure relies on an accurate computation of poles of the transfer function.

Analysis of accumulated timing-jitter in the time domain
IEEE Transactions on Instrumentation and Measurement, 1998This paper deals with the effects of accumulated timing-jitter on the signal-to-noise ratio (SNR) of real sine waves. Such a problem was recently investigated by the author, using the discrete-Fourier method. However, the frequency-domain analysis has some limitations due to the fact that some of the accumulated timing-jitter noise power, found at the ...

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.
