MULTISPECTRAL PANSHARPENING APPROACH USING PULSE-COUPLED NEURAL NETWORK SEGMENTATION
Pansharpening PCNN Image Fusion Multispectral Imaging Remote Sensing Segmentation
2018/5/14
The paper proposes a novel pansharpening method based on the pulse-coupled neural network segmentation. In the new method, uniform injection gains of each region are estimated through PCNN segmentatio...

《Obsessive–Compulsive Disorder And Its Spectrum: A Life-Span Approach》（图）
A Life-Span Approach Obsessive–Compulsive Disorder
2013/12/6
Obsessive–compulsive spectrum disorders are conditions that, while not meeting diagnostic criteria for obsessive–compulsive disorder, share many similar symptoms. This book reviews the latest research...
A hybrid stochastic hierarchy equations of motion approach to treat the low temperature dynamics of non-Markovian open quantum systems
A hybrid stochastic hierarchy equations low temperature dynamics non-Markovian open quantum systems
2014/9/24
The hierarchical equations of motion technique has found widespread success as a tool to generate the numerically exact dynamics of non-Markovian open quantum systems. However, its application to low ...

A general parallelization approach to improve computation efficiency in a global chemical transport model (GEOS-Chem)
MPI OpenMP parallelization GEOS-Chem modeling performance
2017/8/9
Despite increasing processing power of systems, sequential programs have limitations to achieve corresponding performance gains. Parallelization of sequential programs can exploit the computation pote...
A New Approach to the Calculation of N-15 Chemical Shifts of Cyclic Compounds
N-15 chemical shift Additive parameters Regression analysis
2010/4/16
Two sets of additive parameters used previously for the calculation of C-13 chemical shifts of mono and poly six-membered cycloalkanes were applied for the prediction of N-15 chemical shifts of some m...
