Multiplierless discrete Fourier transform based on moments

Tongxin xuebao, 2009
A novel algorithm to perform Discrete Fourier Transform（DFT） multiplierlessly was proposed.First, by modular mapping and truncating Taylor series expansion, the DFT was expressed in the form of the product of the constants and discrete moments.Second, by

Amino‐functionalized lanthanide metal‐organic frameworks encapsulating boron‐doped graphene quantum dots: A paper based fluorescent sensor to visual detection of salicylic acid

FlexMat, EarlyView.
Abstract Salicylic acid (SA), a widely distributed environmental pollutant, requires accurate detection for effective water quality monitoring and ecological protection. In this work, we developed a highly sensitive fluorescent sensor by encapsulating boron‐doped graphene quantum dots (B‐GQDs) within amino‐functionalized lanthanum‐based metal‐organic ...

PNNL‐TUNAMELT: Toward automating the detection of interactions with marine energy devices using acoustic camera sensors

Limnology and Oceanography: Methods, EarlyView.
Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.
