Abrégé
Presented herein are systems and methods related to associating nanobubbles (NBs) with a composition (e.g., a liquid composition). NBs are ultrafine gas domains in liquid with nano-scale diameters that are, on average, smaller than 1000 nm diameter (e.g., about 200nm in diameter or less). NBs have remarkably large interfacial surface areas and have unique physicochemical properties due to their small dimensions. The small size (e.g., diameter) and higher surface tension of NBs increase the interfacial gas-liquid surface area, which in turn promotes mass transfer. In some embodiments, NBs (e.g., oxygen NBs) can be suspended in a composition (e.g., water) long periods of time and produce reactive oxygen species without added catalysts. However, NB applications in water treatment applications have not been widely explored.

Abrégé
Computational fluid dynamics (CFD) computations are performed at time increments using structural properties of the nozzle and flow properties of combustion products flowing through the nozzle. Each CFD computation accounts for movement of the wall geometry of the rocket nozzle due to the flowfield. Structural dynamics computations are performed at each time increment using the CFD computations in order to describe the movement of the wall geometry. Mesh dynamics computations at each time increment redefine the flowfield to account for the movement of the wall geometry. The mesh dynamics computations are based on a spring analogy process. The computations are iterated to solution convergence at each time increment with results being output to an output device.

An angular position sensing system includes a first support with ring-shaped elements disposed thereon and spaced apart from one another in a curvilinear arrangement. Each ring-shaped element includes an electrically-conductive ring and an RFID integrated circuit electrically coupled to its electrically-conductive ring. A second support has an antenna coupled thereto that defines an electrically-conductive path commensurate in size and shape to at least a portion of the electrically-conductive ring. An interrogator transmits a signal to the antenna wherein electric current is generated along the antenna's electrically-conductive path and electromagnetic energy emanates from the antenna. Any ring-shaped element and its RFID integrated circuit energized by the electromagnetic energy generates in response a data transmission for receipt by the interrogator. A processor coupled to the interrogator derives information related to an angular position of one of the first support and second support using the data transmission.

An apparatus and method of wirelessly powering an aerospace vehicle while the vehicle is on the ground is provided to solve a problem of supplying electric power for aircraft while idling on taxiways. Present systems typically require fuel-driven auxiliary power units (APU's) to generate electricity. Running APU's to power aircraft while idling requires over 443 million gallons of jet fuel annually at a cost of $1.3 billion dollars. This results in an estimated 4.7 megatons of carbon dioxide emissions annually. At the gate, shore power is provided via hardline connection.

Chemical pretreatments are used to produce usable water by treating a water source with a chemical pretreatment that contains a hexavalent chromium and an acid to generate a treated water source, wherein the concentration of sulfate compounds in the acid is negligible, and wherein the treated water source remains substantially free of precipitates after the addition of the chemical pretreatment. Other methods include reducing the pH in urine to be distilled for potable water extraction by pretreating the urine before distillation with a pretreatment solution comprising one or more acid sources selected from a group consisting of phosphoric acid, hydrochloric acid, and nitric acid, wherein the urine remains substantially precipitate free after the addition of the pretreatment solution. Another method described comprises a process for reducing precipitation in urine to be processed for water extraction by mixing the urine with a pretreatment solution comprising hexavalent chromium compound and phosphoric acid.

An extremum-seeking control system for formation flight that uses blended performance parameters in a conglomerate performance function that better approximates drag reduction than performance functions formed from individual measurements. Generally, a variety of different measurements are taken and fed to a control system, the measurements are weighted, and are then subjected to a peak-seeking control algorithm. As measurements are continually taken, the aircraft will be guided to a relative position which optimizes the drag reduction of the formation. Two embodiments are discussed. Two approaches are shown for determining relative weightings: “a priori” by which they are qualitatively determined (by minimizing the error between the conglomerate function and the drag reduction function), and by periodically updating the weightings as the formation evolves.

A method of forming a smooth aerodynamic surface that permits laminar flow of air over the smooth aerodynamic surface. Selected portions of a surface of a substrate material are ablated utilizing a laser to form a treated substrate surface having a predefined roughness. The treated substrate surface is coated to form a solid layer of material having a smooth aerodynamic surface that promotes laminar flow. The solid layer of material has a lower modulus of elasticity than the substrate material to provide durotaxis when an insect impacts the solid layer of epoxy material to thereby reduce adhesion of insect residue or other matter to the smooth aerodynamic surface.

An eye movement-based methodology and assessment tool may be used to quantify many aspects of human dynamic visual processing using a relatively simple and short oculomotor task, noninvasive video-based eye tracking, and validated oculometric analysis techniques. By examining the eye movement responses to a task including a radially-organized appropriately randomized sequence of Rashbass-like step-ramp pursuit-tracking trials, distinct performance measurements may be generated that may be associated with, for example, pursuit initiation (e.g., latency and open-loop pursuit acceleration), steady-state tracking (e.g., gain, catch-up saccade amplitude, and the proportion of the steady-state response consisting of smooth movement), direction tuning (e.g., oblique effect amplitude, horizontal-vertical asymmetry, and direction noise), and speed tuning (e.g., speed responsiveness and noise). This quantitative approach may provide fast and results (e.g., a multi-dimensional set of oculometrics and a single scalar impairment index) that can be interpreted by one without a high degree of scientific sophistication or extensive training.

Abrégé
Systems and methods are provided for designing and fabricating contact-free support structures for overhang geometries of parts fabricated using electron beam additive manufacturing. One or more layers of un-melted metallic powder are disposed in an elongate gap between an upper horizontal surface of the support structure and a lower surface of the overhang geometry. The powder conducts heat from the overhang geometry to the support structure. The support structure acts as a heat sink to enhance heat transfer and reduce the temperature and severe thermal gradients due to poor thermal conductivity of metallic powders underneath the overhang. Because the support structure is minimally or not connected to the part, the support structure can be removed with minimal or no post-processing step.

Abrégé
A non-pyrotechnic, normally-closed, zero-leak valve is a replacement for the pyrovalve used for both in-space and launch vehicle applications. The valve utilizes a magnetostrictive alloy for actuation, rather than pyrotechnic charges. The alloy, such as Terfenol-D, experiences magnetostriction, i.e. a gross elongation, when exposed to a magnetic field. This elongation fractures a parent metal seal, allowing fluid flow through the valve. The required magnetic field is generated by redundant coils that are isolated from the working fluid.

The present invention is an improved fiber optic sensing system (FOSS) having the ability to provide both high spatial resolution and high frequency strain measurements. The inventive hybrid FOSS fiber combines sensors from high acquisition speed and low spatial resolution Wavelength-Division Multiplexing (WDM) systems and from low acquisition speed and high spatial resolution Optical Frequency Domain Reflection (OFDR) systems. Two unique light sources utilizing different wavelengths are coupled with the hybrid FOSS fiber to generate reflected data from both the WDM sensors and OFDR sensors operating on a single fiber optic cable without incurring interference from one another. The two data sets are then de-multiplexed for analysis, optionally with conventionally-available WDM and OFDR system analyzers.
