Improving on hidden Markov models: An articulatorily constrained, maximum likelihood approach to speech recognition and speech coding

Description: The goal of the proposed research is to test a statistical model of speech recognition that incorporates the knowledge that speech is produced by relatively slow motions of the tongue, lips, and other speech articulators. This model is called Maximum Likelihood Continuity Mapping (Malcom). Many speech researchers believe that by using constraints imposed by articulator motions, we can improve or replace the current hidden Markov model based speech recognition algorithms. Unfortunately, previous… more

Exhaust gas sensors. CRADA final report for CRADA Number 94MULT-912ES

Description: This project was canceled shortly after final approval. Thus, there are no accomplishments. The major problem encountered was the extreme effort required to obtain approval (about two years) to start work. No lessons were learned. No close-outs items require addressing. No contracts were let. Only two commitments were scheduled to be completed before the Y-12 cancellation: both involved the industrial partners: (1) the industrial partners were to define the preferred sensor power requirements, … more

Novel approaches to the production of higher alcohols from synthesis gas. Quarterly technical progress report No. 17, October 1, 1994-- December 31, 1994

Description: A series of experiments in which the stirrer speed was varied during a methanol synthesis run with BASF S3-86 catalyst showed that mass transfer limitations were present at 750 psig reactor pressure and at space velocities of 5000 and 10000 sl/kg(cat.)-hr.. There was no effect of stirrer speed on reaction rate at 2500 psig reactor pressure and 16500 sl/kg(cat.)-hr. space velocity. However, this was probably due to a close approach to equilibrium rather than to the lack of a mass transfer effect… more

Adsorption and desorption of sulfur dioxide on novel adsorbents for flue gas desulfurization. Final report, September 1, 1994--February 29, 1996

Description: A sol-gel granulation method was developed to prepare spherical {gamma}-alumina granular supports and supported CuO granular sorbents for flue gas desulfurization. The prepared {gamma}-alumina supported CuO sorbents exhibit desirable pore structure and excellent mechanical properties. The sorbents contain higher loading (30-40 wt. %) of CuO dispersed in the monolayer or sub-monolayer form, giving rise to a larger SO{sub 2} sorption capacity ({gt}20 wt.%) and a faster sorption rate as compared t… more

Novel approaches to the production of higher alcohols from synthesis gas. Quarterly technical progress report No. 20, July 1, 1995--September 30, 1995

Description: Standard thermal stability tests were carried out on four liquids: decahydroquinoline (DHQ); 1, 3-Di-4 piperidylpropane (134PPDP), Naphthenic Base 37 and tetrahydronaphthalene (tetralin). Tetralin was more stable than decahydronaphthalene (Decalin{reg_sign}), and THQ was slightly less stable. Both tetralin and THQ should be evaluated further as slurry liquids in the presence of catalyst and syngas. Naphthenic Base 37 and 134PPDP do not have satisfactory thermal stability. Vapor pressure osmomet… more
