Methods and apparatus are disclosed for assessment of microstructural defects in a large structure. Third order elastic constants engender nonlinear excitation of acoustic modes particularly at points of local stiffness changes or stress concentration such as ends of microcracks. A broadband multimode acoustic signal is transmitted through an interrogation region from a first transducer, whereby a second transducer receives an acoustic signal containing linear and nonlinear components. Linear terms are canceled, and a magnitude of the nonlinear acoustic response is measured using time-resolved spectral analysis, to determine a coefficient for acoustic nonlinearity of the interrogation region that serves as a qualitative or quantitative representation of microcrack damage. Broadband signals avoid mode-specific effects such as shadowing or phase mismatch. Damage location can be identified by region or time-of-flight. Portable or dedicated embodiments can be deployed on a wide range of structures of arbitrary shape.

Abrégé
Systems and devices are disclosed to generate a multidimensional mass fingerprint that allows for identification on a low-resolution mass spectrometer equipped with post-ionization fragmentation. For this approach, rather than interrogating a sample that is processed into peptides using a single high resolution MS scan as in traditional fingerprinting, a raw unprocessed sample (containing all biochemical species: lipids, proteins, peptides, and metabolites) is analyzed by combining Matrix-Assisted Laser Dissociation/Ionization (MALDI) ionization with low resolution tandem mass spectrometry. The proposed system combines improvements in MS hardware and software with state-of-the-art machine learning (ML) approaches to usher in rapid biological detection. This technique does not require any prior separation (liquid or gas chromatography) and is therefore rapid (e.g. less than 5 sec) and amenable to high throughput (e.g. greater than 384 samples/hr).

A system for multiple burns from a solid fuel rocket motor may extinguish rocket fuel after the rocket has been ignited. The motor may be extinguished via rapid decompression of the combustion chamber. The fuel may then be reignited by a suitable igniter, and the process of extinguishing and reigniting may be repeated, enabling multi-burn maneuvers. A decompressive extinguishing plug nozzle may extinguish solid rocket fuel after the rocket has been ignited and/or keep a rocket in a disarmed (zero thrust) state until the rocket is to be armed. The nozzle may include a plug that mostly impedes the opening of the nozzle and an outer cowl that is movable to rapidly decompress the combustion chamber. This rapid decompression extinguishes the solid rocket fuel. In some aspects, the fuel can be reignited and extinguished multiple times.

A signal processing method and apparatus quantifies signal “character” in the frequency domain from highly complex signals in a statistically consistent manner. Particular aspects focus on spectral density analyses such as skewness spectral density (SSD), kurtosis spectral density KSD), and probability spectral density (PDSD), among other types of spectral density. Applications of the inventive technique enable not only identification of signal characteristics, but also quantification of signal behavior in an explainable way. Higher orders of spectral densities are 1) physical and statistical, 2) convergent with boundable error, 3) integrable and relatable to the time-domain, and 4) typically differentiable.

Microwave ignition systems with a launcher affixed to or located within a gun spindle. Use of a planar, impedance matched system that include a launcher affixed to or located within a gun spindle and a receiver affixed the propelling charge, where the receiver is engineered and impedance matched to efficiently deposit energy into the receiving igniter material, may result in significantly better timing and reliability than conventional mechanical gun ignition systems and other microwave ignition systems. A pressure-tolerant feed through system can route the microwave energy to the inside of the breech.

Abrégé
Systems and devices are disclosed to generate a multidimensional mass fingerprint that allows for identification on a low-resolution mass spectrometer equipped with post-ionization fragmentation. For this approach, rather than interrogating a sample that is processed into peptides using a single high resolution MS scan as in traditional fingerprinting, a raw unprocessed sample (containing all biochemical species; lipids, proteins, peptides, and metabolites) is analyzed by combining Matrix-Assisted Laser Dissociation/Ionization (MALDI) ionization with low resolution tandem mass spectrometry. The proposed system combines improvements in MS hardware and software with state-of-the-art machine learning (ML) approaches to usher in rapid biological detection. This technique does not require any prior separation (liquid or gas chromatography) and is therefore rapid (e.g. less than 5 sec) and amenable to high throughput (e.g. greater than 384 samples/hr).
The present disclosure provides system and method embodiments for extracting and separating rare earth elements (REEs) from various starting materials and sources. The system and method embodiments disclosed herein facilitate efficient REE extraction, separation, and/or isolation, even when the REEs are present in a starting material at a relatively low level compared to undesirable metals co-present in the starting material. In at least some examples, the disclosed system and method embodiments may be used to recover one or more REEs from coal derived acid mine drainage.
