How SPARK helps provide that this cyber-physical system will operate as specified. This is Part 3 of the four-part series on ...

Measurement invariance refers to the extent to which a psychometric instrument measures the same underlying construct across different groups or conditions. Establishing invariance is fundamental to ...

Abstract: —Frequency Diverse Array (FDA) radar uses small frequency offsets across antenna array elements to generate a range-angle dependent beampattern. A well-known limitation, however, is that the ...

Abstract: Traditional voltage transformers exhibit nonlinear distortion and frequency dependence in harmonic measurements. The optical voltage sensor (OVS) theoretically enables to measure harmonics, ...

T-symmetry, or time reversal symmetry, is a fundamental concept in physics that asserts the mathematical form of physical laws remains unchanged when time is reversed. This principle challenges the ...

Smartphone-based pupillometry offers potential for widespread neurological monitoring in critical care, including for stroke patients in both hospital and post-hospital rehabilitation settings.

ABSTRACT: Peanuts pods grow underground and mature unevenly, resulting that choosing the correct time to harvest is more complicated than other crops. Pod maturity can be determined by blasting with a ...

ABSTRACT: Planetary gear train is a critical transmission component in large equipment such as helicopters and wind turbines. Conducting damage perception of planetary gear trains is of great ...

Garmin watches are known for their robust activity tracking, but that’s not all these fitness watches can do. Over the years, the company has been adding wellness features to its lineup of watches.

Unlike the Berry phase, the orbital angular momentum (OAM) of magnons with two-dimensional wave vector k in band n is not gauge invariant for arbitrary phase λn(k) and so is not physically observable.
