Efforts to apply active noise and vibration control commercially, while intensifying, continue to be hampered by the cost of the computers required to implement the active algorithms. Currently, the cost of wide-band control is prohibitive for lightly damped systems such as precision structures or highly reverberant acoustic spaces, even if the system has just one canceling actuator and one error ...

This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative human-computer controversy over how to implement such capabilities, including how to ascertain the ...

The Air Force has identified the need to develop affordable flight control technology to support Air Force Global Engagement objectives. Of particular interest to the Air Force is the development of real-time optimization algorithms for cooperative engagement solutions among Uninhabited Air Vehicles (UAV) in a multiple target environment. DSR proposes developing a real-time, rule based, Cooperat ...

This project involves research and development of a means for reusing existing digital models and test vectors generated using the LASAR and HITS ATPG for digital test programs that are currently hosted on absolete and non-supported automatic test equipment. The approach identified herein promotes translation of LASAR and HITS ATPG into VXIbus-compatible instrument functions that are interoperabl ...

An ultrasonic Rayleigh surface wave method is propose to determine residual stress depth profile in aluminum aircraft wheels. The Rayleigh wave method has several distinct advantages. The residual stress depth profile can be easily obtained by altering the penetration depth of the Rayleigh wave. The Rayleigh wave is bound to the surface of the wheel, enabling measurements on curved and ...

An ultrasonic method is proposed to determine the level of pre-tension in rails of the high speed test-track. The specific ultrasonic approach has the benefits of being able to perform measurements without the need to account for the texture in the sample and can be used on structures with irregular geometries. The ultrasonic technique can also be used to establish the temperature dependent chan ...

This SBIR Phase I project aims to develop a capacitive energy storage system for UPS applications. The challenge is taken in consideration of the dielectric materials, the design of the capacitor array, and the discharge regulation in the circuit. The innovation emphasizes the development of capacitors with nanostructured dielectrics, in which the discharge process is governed by distributed rel ...

Graphite carbon electrodes have been used as the anode in recently commercialized rechargeable lithium batteries. However, the energy densities achieved to date for secondary lithium batteries have fallen far short of the theoretically attained mark. The specific energy or capacity of the Li-ion system, and for the anode process in particular, the Li intercalation efficiency, and the irreversibl ...

As organizations move toward increased performance measurement and accountability, there is an increasing need to measure job performance at the individual worker level. Traditional assessment tools have been criticized as measuring test taking skills more than job performance skills. A number of approaches have been developed to address this weakness by measuring performance in practical proble ...
