|
| Use of kinematic data in mathematical modeling often requires a consistent set of kinematic variables from the acceleration to the displacement level. A method termed Marjorization was previously developed to combine photographic and sensor- derived variables in an optimal way to produce a consistent set of kinematic variables, which are called Marjorized variables. The computer program that implemented this method was developed in the 1980s on the UNIVAC computer. To ... |

The present investigation sought to evaluate the extent of transfer between real motion and visually-induced apparent motion. In addition, the direction of motion was varied and these two factors, mode of exposure and direction of rotation, were examined in a ... |

| An objective statistical method for isolating timesharing components of performance is described and demonstrated. During the first stage of this method, partial correlation analysis is used to remove the variance attributable to the single-task measures. During the second stage, the resulting dual-task partial correlations are subjected to a form of factor analysis. Data from both Sverko (1977) and Wickens, Mountford, and Schreiner (1981) were reanalyzed and the results compared with ... |

Thus, programs which produced graphic output in the Fourier environment could not run in the RTE environment and conversely. Therefore, it was necessary to develop a standard package of plot subroutines that could run under any operating system. The package is comprised of several FORTRAN ... |

M. S. Weiss; NAVAL BIODYNAMICS LAB NEW ORLEANS LA
|
| The one-sample Kolmogorov-Smirnov goodness-of-fit test (KS) is designed for use with independent data and can be highly sensitive to correlated data. Standard critical values for KS cannot be used with data with known correlations. For data with EEG-like spectra (low frequency, high amplitude spectral peaks) an empirically derived correction for KS provides correct critical values and retains much of the power of the original KS. The correction is based on ... |

M. R. Seemann; NAVAL BIODYNAMICS LAB NEW ORLEANS LA
|
| An error was recently discovered in the CALSPAN 3-dimensional Crash Vehicle Simulation (3DCVS) computer program which causes gross errors in the results when massless segments are used. Additionally even after the error had been corrected, unacceptable computational errors were evident in the 3DCVS output results when a massless segment was used. The sources of the errors were investigated and the significant findings and recommendations resulting form this investigation are presented ... |
