The Variable Similarity Based Modeling and Virtual Signal Generation algorithms are applied to continuously predict (infer) the values of flow rates and component fractions in between periodic oil well tests. This method uses the time-varying signals collected during irregular well tests to train a nonparametric regression model which represents th...

A comparison between the spatial and temporal requirements for designing adaptive-optic correction systems for aero-optical turbulence over the pupil of a turret on the side of an airborne platform is presented. These systems are necessary to mitigate the deleterious aero-optic effects on an optical beam and to reopen the field of regard. The deriv...

A method for extracting the convection speed and direction of aberrations present in wavefronts due to aero-optical turbulence over the pupil of a turret on the side of an airborne platform is addressed. The method is applied to data from the Airborne Aero-Optics Laboratory (AAOL). Such convection information is useful in designing feed-forward ada...

This paper addresses a method for extracting the convection speed and direction of aberrations present in wavefronts due to aero-optical turbulence over the pupil of a turret on the side of an airborne platform.

Two-dimensional wavefronts were collected in the span-wise direction of a weakly-compressible two-dimensional shear layer. The measurements were made in an attempt to determine the character of the flow in the braid region between coherent structures of the convecting vortical structures. Multiple measurements were taken, including individual wavef...

A novel two-dimensional high-bandwidth Shack-Hartmann wavefront sensor was designed and tested, addressing the high temporal bandwidth of aero-optical aberrations caused by compressible flows. The principle of operation and modifications from an earlier version of the wavefront sensor are presented and compared with a commercially available wavefro...

A novel Shack-Hartmann high bandwidth two-dimensional wave front sensor was designed and tested, addressing high temporal bandwidth light aberrations due to light-fluid interaction. The new sensor's principles of operation and modifications are presented, and compared against a commercially-available two-dimensional wave front sensor with a 33x44 s...
