Microcalcification enhancement and classification on mammograms using the wavelet transform
(2008-11-24)
This paper presents a method to enhance microcalcifications and classify their borders by applying the wavelet transform. Decomposing an image and removing its low frequency sub-band the microcalcifications are enhanced. ...

Make-take decisions under high-frequency trading competition
(Elsevier B.V., 2019)
© 2019 Elsevier B.V.The make-take preferences of investors depend on high-frequency trading (HFT) competition, under which HFT firms endogenously acquire speed and informational advantages. In the case where there are many ...
Measurements of Extremely Low Frequency Waves (1-12 Hz) Produced by Ionospheric High-Frequency Waves
(IEEE, 2017)
In a recent study, a process for the generation of Extremely Low Frequency (ELF) waves in the range of 1-12 Hz produced by diamagnetic currents generated by heat in ionosphere by high frequency (HF) waves has been proposed. ...
Wavelet shrinkage: High frequency multipath reduction from GPS relative positioning
(Springer, 2004-01-01)
The wavelet transform is used to reduce the high frequency multipath of pseudorange and carrier phase GPS double differences (DDs). This transform decomposes the DD signal, thus separating the high frequencies due to ...
