Xviii. Speech Communication'

The objectives of our work are to further our understanding of (a) the process whereby human listeners decode an acoustic speech signal into a sequence of discrete linguistic symbols, such as phonemes; and (b) the process whereby human talkers encode a sequence of discrete linguistic symbols into an acoustic signal. Current research activities related to these objectives include studies, aided ...

Experimental investigation, modeling, and optimization of combined electro-(fenton/coagulation/flotation) process: design of experiments and artificial intelligence systems

In this study, a combined electro-(Fenton/coagulation/flotation) (EF/EC/El) process was studied via degradation of Disperse Orange 25 (DO25) organic dye as a case study. Influences of seven operational parameters on the dye removal efficiency (DR%) were measured: initial pH of the solution (pH0), applied voltage between the anode and cathode (V), initial ferrous ion concentration (CFe), initial...

Xviii. Cutaneous Sensory Mechanisms

We have previously reported1 that dogs raised in restriction cages from puppyhood to maturity have greater difficulty than normally reared littermates in performing a simple black-white discrimination and in subsequent reversal training. Since the restricted dogs had some patterned visual stimulation in their cages, their difficulty in performing a discrimination and then utilizing it in a new ...

Tritiated Digoxin XVIII

Tritiated digoxin turnover studies were performed in nine children aged 4 days to 7 years. Mean serum turnover time was 32.5 (range 18-48) hours, and the 3-day urine and stool excretion was 55% of the total dose administered. These findings are quite similar to those observed in adults and indicate that the larger doses of digoxin required for digitalization in infants are not accompanied by in...
