IT IS A RECOGNIZED PROBLEM THAT CURRENT COMPUTER AIDED DESIGN (CAD) AND COMPUTER AIDED ENGINEERING (CAE) INTERFACES(1) LIMIT PRODUCTIVITY OF HUMAN DRAFTSPERSONS, (2) DENY CONCEPT SUPPORT TO PRODUCT DEFINERS, AND (3) INHIBIT USE OF THESE SYSTEMS FOR DELIVERY OF KNOWLEDGE BASED CONCURRENT ENGINEERING SUPPORT. THESE PROBLEMS LIMIT INITIATIVES TO BOTH PRODUCE BETTER FIRST DESIGNS AND TO REDUCE THE PRO ...

THIS PROPOSED PROJECT WILL CREATE A SERIES OF SKILL-BUILDINGMATERIALS AIMED AT MEETING THE SPECIAL NEEDS OF BLIND STUDENTS STUDYING MATHEMATICS. MANY EXPERTS HAVE POINTED TO BRAILLE SKILLS AS CENTRAL TO EDUCATIONAL PROGRESS FOR BLIND STUDENTS; SKILL IN USING NEMETH CODE (THE BRAILLE CODE FOR MATHEMATICS AND SCIENCE NOTATION) IS ESPECIALLY CRUCIAL FOR PROGRESS IN MATH AND SCIENCE. RECENT TRENDS IN ...

ENGINEERING APPLICATIONS OF LAYERED COMPOSITES OR LAMINATES ARE VERY IMPORTANT AND DIVERSE. INTERLAYER CRACKSOR DELAMINATIONS IS ONE OF THE MAJOR REASONS OF COMPOSITE STRUCTURAL FAILURE. DELAMINATIONS MAY CAUSE CONSIDERABLE DEGRADATION OF STIFFNESS AND STRENGTH OF COMPOSITE STRUCTURES. THIS PHENOMENON HAS RECEIVED CONSIDERABLE ATTENTION IN RECENT YEARS. BUT, TO ACHIEVE A DEEPER INSIGHT INTO THE PR ...

DIMENSION TECHNOLOGIES INC. ("DTI") PROPOSES TO RESEARCH AND DEVELOP A TECHNOLOGY THAT WILL ALLOW THE MANUFACTURE OF VERY HIGH RESOLUTION AUTOSTEREOSCOPIC (3D) DISPLAYS FOR ADVANCED COMPUTER APPLICATIONS. THIS INNOVATIVE TECHNOLOGY WILL PROVIDE THE SCIENTIFIC COMMUNITY A TRUE 3D ALTERNATIVE TO CURRENT 3D AND 2D IMAGING SYSTEMS. DTI HAS DEVISED A METHOD THAT ALLOWS THE DISPLAY OF IMAGES WITH A RESO ...

THIS PROPOSAL IS TO CONDUCT RESEARCH IN A NOVEL FREQUENCY HOPPING CODE DIVISION MULTIPLE ACCESS (FH/CDMA) PERSONAL COMMUNICATIONS NETWORK (PCN). THIS MOBILE CELLULAR COMMUNICATIONS SYSTEM, WHICH IS TO BE DESIGNED TO MAXIMIZE THE NUMBER OF USERS PER CELL, CAN OPERATE IN A FREQUENCY BAND CONTAINING OTHER USERS. IN ORDER TO MAXIMIZE THE NUMBER OF USERS, SYNCHRONOUS FH/CDMA WILL BE EMPLOYED. FORWARD E ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

THE PROPOSED WORK REPRESENTS A NEW, INNOVATIVE APPROACH IN THE DEVELOPMENT OF IMPROVED HIGH RESOLUTION DISPLAYS. THE CORE FEATURE OF THIS NEW DISPLAY CENTERS ON CONSTRUCTION OF A REVOLUTIONARY NEW LIGHT VALVE WHICH COMBINES STATE-OF-THE-ART CAPABILITIES IN VLSI AND LIQUID CRYSTAL (LC) TECHNOLOGIES. WITH THIS NEW LIGHT VALVE, IT IS, IN PRINCIPLE, POSSIBLE TO CONSTRUCT DISPLAYS WHICH WOULD HAVE PIXE ...

COMMERCIALLY AVAILABLE ION SELECTIVE MEMBRANES WILL BE MODIFIED TO MEET BETTER THE NEEDS OF ORGANIC ELECTROSYNTHETIC PROCESSES. MOST MEMBRANES UTILIZED TODAY WERE SPECIFICALLY DESIGNED FOR EITHER THE CHLORALKALI INDUSTRY OR FOR ELECTRODIALYSIS. AN ELECTROORGANIC PROCESS,HOWEVER, PLACES DIFFERENT REQUIREMENTS ON THE MEMBRANES. THE EXTENT OF TRANSPORT OF SOLVENT AND OTHER NEUTRAL MOLECULES THROUGH T ...
