A two-layered ventilated thermocline model is matched with inertial western boundary currents in the southern part of the western boundary region. For general cases the western boundary currents break...
A common time scale for the EPICA ice cores from Dome C (EDC) and Dronning Maud Land (EDML) has been established. Since the EDML core was not drilled on a dome, the development of the EDML1 time scale...
Yun et al. (hereafter YPM) have reported results of a study on the radiating instabilities of nonzonal shear flows as a possible source of the energetic internal temperature fluctuations observed in t...
Matching Pursuits方法综述     字典  原子  匹配逼近  快速算法       < 2008/5/17
Matching Pursuits(匹配逼近)算法是在一个确定的函数集合中自适应地选择一些函数来表示一个信号的计算过程,函数集合中的每个函数都称为原子.多样化的信号特征决定了可以精确刻画信号特征的原子的类型,而重复迭代逼近的贪婪算法又确定了运算效率是MP算法的存在和发展的问题核心.本文围绕MP算法中原子库的生成,原子参数的搜索索引方式和迭代逼近过程中的快速算法等方面,阐述了MP算法发展变化过程.
In [6], Guo and Tan have shown that $2$ is a Laplacianeigenvalue of any tree with perfect matchings. For trees withoutperfect matchings, we study whether $2$ is one of its Laplacianeigenvalues. If th...

Let $T$ be a tree with matching number $\mu(T)$. In this paper we obtain thefollowing result: If $T$ has no perfect matchings, then $\mu(T)$ is a lower bound forthe number of nonzero Laplacian eigenva...
In this paper, we introduce a domain decomposition method with non-matching grids for solving Dirichlet exterior boundary problems by coupling of 痭ite element method (FEM) and natural boundary element...
The automatic co-registration of point clouds, representing 3D surfaces, is a relevant problem in 3D modeling. This registration problem can be defined as a surface matching problem. We treat it as l...
