In this approach, the threshold level of stimuli which refers to
absolute threshold is determined by introducing either a gradual increment until stimulus becomes detectable or a gradual decrement until stimulus becomes undetectable.
Then, the constructed brain functional networks were filtered by three thresholding schemes:
absolute threshold, mean degree, and a novel data-driven scheme based on orthogonal minimal spanning trees (OMST), and graph theoretical measures were calculated.
The "
absolute threshold shift" method first defines the present-day threshold temperature in absolute terms ([degrees]C) and then increases it in the future.
A relative threshold defines that line based on a certain percentage of income or spending compared with everyone else; an
absolute threshold sets it at the cost to meet basic needs.
Under low light, ISO 800 is the
absolute threshold, beyond which the colours start deviating from source.
This instrument, which is no longer manufactured, was designed to measure the
absolute threshold of light perception by measuring the logarithm of light threshold against time of dark adaptation for the whole retina, or a specific location.
Hysteresis margin and
absolute threshold are determined to optimize the handover performance in [10].
Another common approach uses an
absolute threshold, rewarding providers if they exceed a specified level of measured quality (e.g., providers with 50 percent or more patients achieving treatment goals) (Institute of Medicine 2006; Doran et al.
Absolute Threshold. To construct a sparse representation for the boundaries,
absolute threshold discards the examples whose associated coefficients [[beta].sub.(1,2)] are close to zero.
Citing the public health implication of fall prevention, and the report by the Institute of Medicine, the authors wrote, "The
absolute threshold level of [vitamin D] needed to prevent falls in an elderly population is not known in part because of lack of true dose-ranging studies....
Thirty-seven adult dyslexic readers and 40 adult normal readers performed a battery of tests measuring auditory temporal processing (gap detection and dichotic temporal order judgment), auditory intensity processing (
absolute threshold and intensity discrimination), auditory spectral processing (spectral temporal order judgment) and working memory (backward digit span).
absolute threshold - the lowest level of stimulation that a person can detect
