Non-oxide based ceramic matrix composites (CMCs), such as Silicon Carbide and Carbon-Carbon, are current state-of-the-art (SOA) refractory thermal protection system (TPS) materials for space reentry vehicle leading edge components and hot structures that...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

IN THE TREATMENT OF THE DYNAMIC PROBLEMS OF STRUCTURES, TWO ALTERNATE TESTING METHODS, BASED ON EXTERNAL AND EMBEDDED SENSORS, EXIST IN THE LITERATURE. IF THE SENSORS RESPOND TO THE CHANGES IN THE DYNAMIC CHARACTERISTICS OF THE STRUCTURE, AND/OR THE ENVIRONMENT, THEN THEY ARE REFERRED TO "SMART" STRUCTURES. SMART SENSORS AND SMART MATERIALS HAVE BEEN USED FOR DETECTING STRUCTURAL DAMAGES AND/OR CO ...
