Abstract

A method for limited-angle sparse computed tomography (CT) reconstruction and is disclosed. The method involves: a) obtaining a sinogram image of an object from a limited number of scan angles; b) constructing sine waves represented in the sinogram image; c) superimposing the sine waves over the sinogram image; and d) creating a Hough Space representation to identify sinusoidal features in the sinogram image. A method for next scan angle prediction to identify and characterize stochastic, internal geometric features of an object is also provided. This method includes: a) identifying intersection angles for pairs of superimposed sine-like features, b) counting the number of intersections at each angle, c) calculating the distance of every unscanned angle from the nearest scanned angle, d) and calculating a score for each unscanned angle. The angle with the highest score is a candidate for the next scan angle. Error metrics for this method are also discussed.

Abstract

The present disclosure defines a morphing airfoil having a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and deflect in response to control inputs to change a lift force without separate movable control surfaces. The anisotropic skin is attached to underlying structure that is both actively controlled and passively supported. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift profile along a span of the airfoil.

Abstract

Abstract

A system for determining a position of a receiver from as few as two or three transmitters. The receiver may be stationary or moving with a known velocity. The system includes a receiver clock having a clock bias and a clock drift relative to a reference clock and may also include a motion sensor. A decoder receives transmitted signals from a number of transmitters and determine pseudo-ranges and transmitter frequencies therefrom and a processing unit receives the pseudo-ranges, the transmitter frequencies and the receiver velocity and determines the position of the receiver therefrom. When only two transmitters are available, the position of the receiver is determined dependent upon a known receiver clock drift. The system may also determine clock bias and, when three or more transmitters are available, receiver clock drift. The processing unit uses ranging and Doppler equations in combination, and may also use a measured velocity.

Abstract

A method for determining the likelihood that a pixel in a video image sequence represents true motion in the image. Light from a scene is captured to yield an original image having a sequence of frames. A prototype image is created from the original image as a geometrically accurate representation of the scene which is substantially free of contamination. A tilt variance-Gaussian mixture model and/or multi-variate Gaussian model, based upon optical turbulence statistics associated with the scene, is developed. Each pixel in the original image sequence of frames is evaluated against the prototype image using a probability density function, to yield a likelihood that the respective pixel represents true motion.

Abstract

A morphing airfoil includes a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and bend in response to control inputs to change a lift force without separate movable control surfaces. A plurality of standoff mounts are attached to an inner surface of anisotropic skin. The standoff mounts include through apertures for receiving a flexible stringer. The anisotropic skin is attached to underlying structure through the flexible stringers. The flexible stringers interface with actuated position control ribs and passive compliant support ribs. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift and drag distributions along a span of the airfoil without separate control surfaces.

Abstract

The present invention relates to a microfluidic flow process for making polymers, polymers made by such processes, and methods of using such polymers. In such process, a novel reagent delivery setup is used in conjunction with microfluidic reaction technology to synthesize anionic polymerization reaction products from superheated monomer orders of magnitude faster than is possible in batch and continuous syntheses. The aforementioned process does not require the cryogenic temperatures which are required for such syntheses in batch or bulk continuous. Thus the aforementioned process is more economically efficient and reduces the environmental impact of linear polymer production.

Abstract

A micro-cavity passive actuator is configured to delay dynamic stall of an airfoil. The micro-cavity actuator is formed in the pressure sidewall surface proximate the leading edge of the airfoil. This cavity remains essentially inactive at low incidence. However, as the wing's effective angle of attack dynamically increases and the stagnation point displaces past the micro-cavity, the accelerating flow grazing the cavity induces a high-frequency resonance phenomenon (known as Rossiter modes). The self-generated small-scale disturbances are carried around the leading-edge through the boundary layer to the wing's upper side where the laminar separation bubble (LSB) amplifies these disturbances. This process delays LSB bursting and dynamic stall. The micro-cavity must be sized such that its naturally emitting oscillations are in a range of frequencies that can be amplified by the LSB.

Abstract

The present disclosure defines a morphing airfoil having a dynamic flexible skin system that is capable of carrying high level aerodynamic (or fluid) pressure loads over a structural surface. The structural surface can morph and deflect in response to control inputs to change a lift force without separate movable control surfaces. The anisotropic skin is attached to underlying structure that is both actively controlled and passively supported. A control system causes the underlying support structure to move to a desired location which in turn causes the skin to bend and/or flex without exceeding a stress threshold and thus vary the lift profile along a span of the airfoil.
