Photophysical characterization of toluene and 3 pentanone for quantitative imaging of fuel/air ratio and temperature in combustion systems
… in modern engine research. However, quantitative interpretation of fluorescence signals in terms of fuel/air ratio or temperature requires sound fundamental knowledge of the compound’s photophysical behavior, i.e. the dependence of the LIF-signal on temperature, pressure and bath gas composition. …

Creep Damage Evolution in 316L Stainless Steel: Correlating Cavitation with Acoustic Emission
… of microstructural defects with sophisticated AE signal interpretation, the study elucidates a strong correlation between the applied stress levels and the trajectory of damage evolution. At the lower stress level (241 MPa), fewer but significantly coarser voids were observed, whereas at the …

Fusion of multiprobe NDT data.
… demonstrates that NDT data fusion can facilitate signal interpretation, defect quantification and provide a solution which may be implemented in the use of remotely operated multiple inspection techniques. Non-destructive testing data integration and fusion applied to the inspection of composite …

On the electrolytic nature of molten aluminum and rare earth oxides
… Previous challenges related primarily to signal interpretation during decomposition voltage measurement have hindered determination of Gibbs energy. An electrolytic cell method is proposed herein utilizing the sensitivity of large amplitude alternating current voltammetry, which enabled …

The study of shear and longitudinal velocity measurements of sands and cohesive soils
… arrival detection. To reduce the uncertainty in signal interpretation, a specimen aspect ratio of 1 was adopted, with a minimum wavelength ratio of 2. The second part of the experimentation consisted of using bender elements on Boston Blue Clay, both intact samples as well as Resedimented Boston …

Machine Learning for Predicting Prosthetic Limb Movements
… movement from surfaced electromyography (sEMG) signals using sequence learning techniques. sEMG signals change over time due to multiple factors such as muscle fatigue or user variability. Traditional prosthetics control methods rely on static feature extraction, ignoring how signals change over …

Optimization of indentification of particle impacts using acoustic emission.
… free-falling or air-borne particle impact AE signals - was correlated with particle size, concentration, height, target material and thickness. For a given system, once calibrated for a specific particle type and operating condition, this technique might be sufficient to serve the purpose. …
