To solve for u(t) numerically, we expand u(t) into a chebyshev polynomial expansion. This expansion is a sum of time dependent coefficeints times the chebyshev polynomials, which form an orthogonal ...

Abstract: Near-infrared (NIR) technology is an essential online measurement and monitoring technology in modern industrial processes. Although various methods have been developed for spectral ...

Abstract: Frequency estimation was a fundamental problem in radar imaging. The classical Fourier spectral analysis suffered from the Rayleigh limit. The imaging performance deteriorated rapidly in low ...

Detecting concealed explosives and chemical threats constitutes a critical challenge in global security, yet current technologies often face significant operational limitations. While X-ray scanners ...

Note: Forking is not recommended. You may not be able to follow up on the progress of the ongoing project. We shall establish an iFEM-like package or a simplified ...

Laser photoacoustic spectroscopy is a mature technology that has been widely applied in various fields, including the analysis of dissolved gases in transformer oil, environmental monitoring, and ...
