Measurement of velocity fields and flow rates is of prime importance in many areas of industry and fluid dynamics research. the research proposed herein would result in a nonintrusive means of determining the magnitude and direction of velocity and the corresponding flow rates by the use of laser… More

A system identification technical is proposed for non-destructive test to detect unbounds in large bonded components. the technique uses the system's time response data due to random input excitation. system's eigenvalues and eigenvectors are retrieved from the time responses and used for the… More

Methods are desperately needed to discern the structural integrity of critical components of weapon systems such as pressure vessel cases. at this time, no technique exists which permits a global monitoring of the operational readiness of any structures, including composite motor cases. the… More

The technical objective of the proposed research is to determine the extent to which language instruction can be implemented and enhanced by the emerging capabilities of computer systems providing personalization, multimedia presentation, and a high degree of human/machine interaction. if… More

The objectives of this work are to develop the pressure and useable energy characteristics for four (4) important explosives. the explosives are pbx-113, pbx-114, pbx-115, and pbx-9404. these analyses will address the close-in regime up to about 10 charge radii from the explosive. the pressure time… More

This investigation intends to evaluate the capability of an established sector shock-tube method for application to lithotripsy. it could provide a quantitatively defined shock wave in terms of wave pressure, duration, energy, and spatial extent for improved patient treatment and use of shock waves… More

The "solvatochromic parameter" database will be expanded andsolubility, distribution, and toxicology properties (xyz) of organic nonelectrolytes will be correlated, rationalized,and predicted through linear solvation energy relationships of the form: xyz = xyz + mv/100 + s pi* + a alpha + b beta,… More

Environmental stress screening (ess) is the tailored application of environmental stresses to manufactured end items to identify and eliminate defective, abnormal, or marginal parts and manufacturing defects. the application of ess to one-shot ordnance devices like fuzes, safe/arming devices and… More

It is proposed to examine a variety of aerosol discrimination techniques especially those concerning recent work on pulse shape and electronic signal processing to obtain improved target detection performance for an active optical fuze in an aerosol environment. based on this study a system concept… More

Two major impediments to the effective use of robotics are 1) the difficulty in developing robust, adaptive, goal-directed behavior based on sensory interactive control and 2) the difficulty in reprogramming a robotic system to carry out new tasks. the objective of this work is to develop a hybrid… More

Dynamics modeling is important for the design, analysis, simulation, and control of robotic and other computer controlled mechanical systems. the formulation of a model and the requirements imposed on the computational algorithmsdiffer from one application to the other. today, accurate modeling can… More
