The U.S. chemical industry accounts for over 200 million tons/year of hazardousliquid waste containing organic chemicals. These waste streams are difficult totreat using conventional technologies such as carbon adsorption and steamstripping. Membrane processes--particularly pervaporation--offer energy and costadvantages over conventional techniques. However, current pervaporationmembrane-module ...

Hexavalent chromium, Cr(VI), in the usual form of oxo species, is used in manyindustrial processes and products. As a consequence, Cr(VI)= containingcompounds are often found in wastewater and contaminated sites. Since Cr(VI) isconsidered highly toxic and carcinogenic, it is extremely important to have areliable, easy-to-use, sensitive monitor for determining Cr(VI) concentrationsin process, on ...

AIDING THE HEARING HANDICAPPED IN PERCEIVING SPEECH BY THE SENSE OF TOUCH REQUIRES FIRST THAT SPEECH CUES BE ACQUIRED AND RECONSTRUCTED TO LOW DATA RATE FORM, COMPARABLE TO THAT CONVEYED BY VISUAL SIGNING AND TACTILE BRAILLE. SEVERAL PROMISING CUE EXTRACTING METHODS ARE DESCRIBED BASED ON EXISTING COVOX WORLD RECOGNITION PRODUCTS AS WELL AS ON STATISTICAL SIGNAL PROCESSING TECHNIQUES WHICH USE OVE ...

THE SPECIFIC OBJECTIVE OF THIS STUDY IS TO EVALUATE THE TECHNICAL FEASIBILITY OF EMPLOYING A FIXED FILM ANAEROBIC DIGESTER SYSTEM TO ACHIEVE AN ADEQUATE DEGREE OF BIOLOGICAL SLUDGE DIGESTION WITH A RETENTION TIME WHICH IS ONE ORDER OFMAGNITUDE SHORTER THAN THAT OF THE CONVENTIONAL SUSPENDED- GROWTH DIGESTER. IN ORDER TO MAXIMIZE THE BIOLOGICAL REACTION RATE, THE INFLUENT SLUDGE WILL BE TREATED WIT ...

KNOWLEDGE SOFTWARE PROPOSES TO DETERMINE THE TECHNICAL FEASIBILITY OF USING A MICROCOMPUTER BASED EXPERT SYSTEM TO ASSIST EDUCATORS IN THE DEVELOPMENT OF INSTRUCTIONAL OBJECTIVES. THIS EFFORT SUPPORTS THE DEPARTMENT OF EDUCATION'S GOAL OF DEVELOPING METHODS TO SIMPLIFY AND IMPROVE COURSEWARE CREATION. WE PROPOSE TO DETERMINE FEASIBILITY BY DEVELOPING A MICROCOMPUTER BASED EXPERT SYSTEM. OUR PLAN I ...
