Space-Efficient Approximation Scheme for Circular Earth Mover Distance
Space-Efficient Approximation Scheme Earth Mover Distance
2012/12/4
The Earth Mover Distance (EMD) between point sets A and B is the minimum cost of a bipartite matching between A and B. EMD is an important measure for estimating similarities between objects with quan...
Determining the wavelength of Langmuir wave packets at the Earth's bow shock

2011/8/5
Abstract: The propagation of Langmuir waves in plasmas is known to be sensitive to density fluctuations. Such fluctuations may lead to the coexistence of wave pairs that have almost opposite wave-numb...
