The ability to efficiently process intelligence data is critical to fighting the global war on terror. A major source of this data is recorded speech. Therefore, the performance of speech processing applications (speech recognition and speaker identification applications, for example) depends on pre-processing to find the regions in the recording where speech is present. Although current method ...

The Navy wants the capability of firing over twenty missiles with Mark 72 boosters compared to about a dozen today, which will require a different ablative material than what is currently used. A solution to this problem is needed to get ahead of the curve for the future fleet operations. There is an opportunity to develop new ablative materials for the Mark 41 Vertical Launch System (VLS) with th ...

THE OVERALL OBJECTIVE OF THE PROPOSED RESEARCH IS TO INVESTIGATE THE USE OF THE ELECTRICAL POTENTIAL DROP TECHNIQUE AS AN ACCELERATED TEST METHOD FOR DETERMINING THE STRESS CORROSION CRACKING RESISTANCE OF HY-130 STEEL WELDMENTS UNDER CATHODIC PROTECTION IN NATURAL SEAWATER AT AMBIENT TEMPERATURES. WELDS WILL BE DEPOSITED IN 1-INCH THICK HY-130 STEEL BUTT JOINTS. COMPACT TENSION FRACTURE-MECHANICS ...

MAX phases are an important class of layered machinable ternary carbides and nitrides that exhibit a unique combination of ceramic and metal properties. In 2011, a new family of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides – called MXenes – was discovered via selective etching of the ‘A’ element from MAX phases. Texas Biochemicals Inc., has ...

Current surveillance systems often use mounted cameras to capture video imagery and a range of sophisticated sensors and stand-alone security devices. These current surveillance systems are often point solutions based on a centralized architecture for surveillance applications. Point solution systems use a single control agent to coordinate the actions of the independent sensors. The manpower need ...

PREDICTION OF CATASTROPHIC AND COSTLY FAILURES IN STRUCTURALCOMPONENTS HAS BEEN HAMPERED BY THE INABILITY TO MEASURE STRESS LEVELS IN CRITICAL COMPONENTS WITH ACCURACY. THIS PROPOSAL DESCRIBES THE STEPS NEEDED TO DEVELOP A STRESS MEASUREMENT SYSTEM THAT RELIES ON ULTRASONIC (ACOUSTOELASTIC) WAVE MEASUREMENTS. THE RECENT ADVANCEMENTSMADE IN THE USE OF CRITICALLY REFRACTED LONGITUDINAL WAVES (CRLW), ...

It is likely that next generation electron sources for future accelerators will initially utilize a direct current gun based injector with a semiconductor photocathode for electron production. The goal of this project is to create a recipe or series of recipes that will immunize a photocathode against the background gasses likely to be found under operation in a generic RF gun, thus reducing or e ...

Balcones Technologies, proposes to adapt actively controlled suspension technology developed for high performance off-road vehicles to address NASA's requirement for Active Vibration Control for Ground Support Equipment (GSE). This innovative approach to meeting NASA needs exploits approximately $23M of highly successful R&D since 1993 at the University of Texas Center for Electromechanics (CEM) ...

Robots will play an important role in NASA#39;s upcoming missions to the Moon and beyond.nbsp; They will need to manipulate their environment in complex and useful ways - carrying objects, using tools, and assisting crew.nbsp; NASArsquo;s humanoid robots have highly dexterous end-effectors, but developing software to fully utilize such hands remains a challenging task.nbsp; Grasping strategies are ...

To address the Navy"s need for an innovative manufacturing processes and materials to produce a shower stall that is affordable, modular, corrosion resistant, water tight, and can be built with the minimal number of standardized components to reduce the production time and overall life-cycle maintenance associated with the system, Texas Research Institute Austin, Inc. (TRI/Austin) proposes to leve ...
