MLD-Based Modeling of Hybrid Systems with Parameter Uncertainty [PDF]

open access: yesIEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009
In this paper, we propose a new modeling method to express discrete-time hybrid systems with parameter uncertainty as a mixed logical dynamical (MLD) model.

Frequency Discrimination and the MLD

The Journal of the Acoustical Society of America, 1972
Binaural frequency difference limens in noise were obtained under homophasic and antiphasic conditions. Signal frequencies of 200, 300, 500, 700, and 1000 Hz were investigated at 5- and 10-dB sensation levels while 500 Hz was also explored at 15, 20, and 25 dB. The masker was a bandlimited noise with a spectrum level of 55 dB.

Metachromatic Leukodystrophy (MLD)

Archives of Neurology, 1983
A 31-year-old woman with adult metachromatic leukodystrophy was seen for a progressive dementia. Computed tomographic scans showed four, nearly mirror-image, hypoabsorptive areas in cerebral white matter. These symmetric bifrontal and biparietal abnormalities were accompanied by mild ventricular enlargement and by a slight to moderate volume loss ...

MLD in Children

Journal of Speech, Language, and Hearing Research, 1997
The first aim of this study was to obtain a more detailed picture of the effect of masker bandwidth (20 Hz to 1000 Hz bandwidth) on the masking level difference (MLD) for a 500-Hz signal as a function of listener age. The results of the pure-tone signal experiment showed that the MLDs of older children differed from adults only for the narrowest masker

MLDs in Forward and Backward Masking

The Journal of the Acoustical Society of America, 1972
Masking-level differences (MLDs) of substantial magnitudes were found in forward and backward masking situations. Their magnitude diminishes exponentially as the silent interval between signal and masker increases. Implications of the data for current models relating to the MLD are suggested.

Microlumbar Discectomy (MLD)

Spine, 1988
This is a retrospective study of microlumbar discectomy (MLD), performed between 1983 and 1987. During that period, 60 patients underwent the procedure. At follow-up, after an average of 33.3 months, MLD provided excellent and good results in 93.3% of cases, fair in 3.3%, and failure in 3.3%.

Manual lymph drainage (MLD)

Journal of the Association of Nurses in AIDS Care, 1998
Treatment review is intended to inform and update nurses about treatments relevant to HIV/AIDS. Information presented in this column does not imply endorsement by ANAC. Additionally, the reader is advised that there is a paucity of scientific data to validate the effectiveness of manual lymph drainage.
