Ordinal comparison of successively presented signal durations requires (a) the encoding of the first signal duration (standard), (b) maintenance of temporal information specific to the standard duration in memory, and (c) timing of the second signal duration (comparison) during which a comparison is made of the first and second durations.
The employment of both millisecond and second durations allowed to better isolate temporal perception mechanisms from more generalized attentional and mnemonic processes.
Millisecond and second durations were used in our study to better isolate deficits specific to temporal processing from more generalized cognitive impairments.
Laser photocoagulation (532 nm wavelength, 75 µm spot size, 0.1 second duration, and 150 mW intensity) was delivered with a slit lamp and a cornea contact lens.
For example, consider a video sequence which is partitioned into segments each with T seg second duration and a server-allocated bandwidth of Ω bit/s.
If threatened, Caribbean reef sharks sometimes perform a threat display, in which they swim in a short, jerky fashion with frequent changes in direction and repeated, brief (1 1.2 second duration) drops of the pectoral fins.
Task parameters were estimated using a Finite Impulse Response model (zero filter order, 2 second duration), and motion parameters were calculated from the initial Siemens PACE/MoCo series data and added to the design matrix as a nuisance variable.
All images were acquired as videos of 2 second duration, and contained 21 frames.
And second, the duration and amplitude of the cycles differ depending on whether one admits asymmetries in the shocks of the trend component, or on those of the cyclical component as well.
Lange appears to base his assertion, first, on the fact that most of the asbestos at the World Trade Center was chrysotile asbestos, and second, that duration of exposure for most workers was brief.
