THIS RESEARCH STUDY DEVELOPS AN INTERACTIVE, MICROCOMPUTER-BASED, PICTURE ICON LAYOUT AND AUTHORING SYSTEM FOR EDUCATORS, COMMUNICATIONS SPECIALISTS, AND EDUCATIONAL TECHNOLOGISTS WHO ADAPT OR FABRICATE COMMUNICATIONS AIDS AND SYSTEMS FOR NON-VOCAL OR SPEECH-IMPAIRED CHILDREN OR ADULTS. A PROTOTYPE PICTURE ICON LAYOUT SOFTWARE (PILS) SYSTEM WILL BE DESIGNED FOR THE UNICORN II EXPANDED KEYBOARD (UN ...

AICOM PLANS TO DEVELOP A LOW COST, HIGH QUALITY SPEECH SYNTHESIZER CHIP WHICH MAY BE USED IN THE VISUALLY IMPAIRED MARKET, IN THE EDUCATION MARKET, AND IN THE COMMERCIAL MARKET. IN THIS PHASE, WE PLAN TO STUDY THE ARCHITECTURE OF THE CHIP, THE COMPLEXITY OF THE CIRCUIT, THE POSSIBLE DIE SIZE, THE POWER CONSUMPTION, AND THE TOTAL COST OF PRODUCING THE CHIP. IN ADDITION, WE PLAN ON RUNNING A COMPUTE ...

TWO NEW COMPUTER TECHNOLOGIES PROFOUNDLY CHANGING TEACHING TOOLS ARE MULTIMEDIA TECHNOLOGIES AND DO-IT-YOURSELF PROGRAMMING TECHNOLOGIES. BOTH ARE EMBODIED IN APPLE MACINTOSHC'S HYPERCARD. THESE NEW DEVELOPMENTS ENABLE TEACHERS TO USE, MODIFY, AND CREATE TEACHING MATERIALS THAT COMBINE VISUAL AND AUDITORY MEDIA TO ENHANCE THE LEARNING PROCESS OF ALL STUDENTS AND TO HELP REMEDIATE CERTAIN KINDS OF ...

SOIL WASHING OR FLUSHING HAS BEEN SHOWN TO BE AN EFFECTIVE METHOD FOR REMOVING HEAVY METALS FROM METAL-CONTAMINATED SOILS AT SUPERFUND SITES. SANDY SOILS CAN OFTEN BE WASHED WITH WATER TO MOBILIZE METAL IONS IN AN AQUEOUS PHASE, BUT FOR CLAY SOILS OR SOILS WHICH CONTAIN INSOLUBLE METAL COMPOUNDS, E.G., LEAD SULFATE, OTHER ADDITIVES SUCH AS CHELATING AGENTS (EDTA) ARE USED TO EFFECT TRANSFER OF MET ...

A NEW ADSORPTION--CATALYTIC COMBUSTION SYSTEM WITH APPLICATION TO REMOVAL OF VOLATILE ORGANIC COMPOUND (VOC) EMISSIONS FROM INDUSTRIAL PROCESSES AND COMMERCIAL OPERATIONS ESPECIALLY WHERE LOW CONCENTRATIONS OF VOC ARE PRESENT IN HIGH FLOWS OF OFF-GAS WILL BE INVESTIGATED IN THIS DEMONSTRATION PROGRAM. THIS SYSTEM WILL HAVE THE BENEFITS OF LOW EQUIPMENT COSTS, SIMPLE OPERATION, LOW ENERGY UTILIZATI ...

MCLEAN MEDIA PLANS TO RESEARCH, DESIGN, PRODUCE AND EVALUATEA PROTOTYPE MODULE FOR TEACHING SCIENCE CONCEPTS TO LEARNINGDISABLED, MIDDLE SCHOOL (GRADES 6-8) STUDENTS USING A COMPUTER-BASED, MULTIMEDIA SYSTEM. THE PROTOTYPE WILL INCORPORATE TEXT, GRAPHICS, SOUND AND VIDEO USING HYPERCARD SOFTWARE, AN APPLE MACINTOSH COMPUTER AND A VIDEODISC WITH "REPURPOSED" VIDEOTAPE MATERIAL. RESEARCH WILL FOCUS ...

APPROXIMATELY 1.3 MILLION TONS OF HYDROCARBON VAPORS ARE RELEASED ANNUALLY IN PETROLEUM STORAGE AND TRANSFER OPERATIONS. THIS PROPOSAL DESCRIBES THE DESIGN AND LABORATORY DEMONSTRATION OF A PILOT MEMBRANE SYSTEM ABLE TO CONCENTRATE AND RECOVER THESE VAPORS FROM STORAGE TANK OFF GASES. IN THE PHASE I PROGRAM, EXISTING MEMBRANES WILL BE EVALUATED WITH MODEL GAS MIXTURES IN THE LABORATORY. THESE DATA ...
