In these two talks, I will present a unified method to construct soliton solutions to NLS type equations by the KP-Toda reduction approach. I will take the NLS equation as a typical example and show h...
High cadmium pollution from sediments in a eutrophic lake caused by dissolved organic matter complexation and reduction of manganese oxide
eutrophication lake pollution dissolved organic matter DOM DGT
2021/7/27
Eutrophication and metal pollution are global environmental problems. The risk of metal pollution is high in the eutrophic lakes because of high mobility of metal in sediments.

Buried Ionizable Amino Acids Reduction Potential Recombinant Myoglobin
2016/5/20
The temperature dependences of the reduction potentials (E degrees') of wild-type human myoglobin (Mb) and three site-directed mutants have been measured by the use of thin-layer spectroelectrochemist...
SINGLE-AND TWO-CHANNEL NOISE REDUCTION FOR ROBUST SPEECH RECOGNITION IN CAR
automatic speech recognition robustness car noise two-channel noise reduction
2015/9/29
Hands-free operation of a mobile phone in car raises major challenges for acoustic enhancement algorithms and speech recognition engines. This is due to a degradation of the speech signal caused by re...
Comparison of Wavelet and FFT Based Single Channel Speech Signal Noise Reduction Techniques
DWT DWPT wavelet wavelet packet FFT noise control speech enhancement noise cancellation filter

This paper compares wavelet and short time Fourier transform based techniques for single channel speechsignal noise reduction. Despite success of wavelet denoising of images, it has not yet been widel...
Possible reduction of earthquake hazard on the Wellington Fault,New Zealand,after the nearby 1855,M 8.2 Wairarapa earthquake and implication for interpreting paleoearthquake intervals
Wellington region changes on Coulombfailure stress earthquake hazard
2015/9/16
Based on the indicative modelling, the changes in Coulomb failure function (?CFS) suggest that the W-HV segment and the T-P segment could be stable in at least the future 300 years and 190 years respe...
Reduction in the ionospheric error for a single-frequency GPS timing solution using tomography
GPS ionosphere tomography timing single-frequency
2015/8/28
Single-frequency Global Positioning System (GPS) receivers do not accurately compensate for the ionospheric delay imposed upon a GPS signal. They rely upon models to compensate for the ionosphere. Thi...
