Least squares 3D surface matching Point clouds Registration Laser scanning Correspondence searching
2015/8/13
An algorithm for least squares matching of overlapping 3D surfaces is presented. It estimates the transformation parameters between
two or more fully 3D surfaces, using the Generalized Gauss-Markoff ...

Electromagnetic corrections to K ->pi pi. II. Dispersive matching
Electromagnetic virtual photons chiral perturbation theory the model of the resonance
2014/12/22
We express the leading electromagnetic corrections in K → ππ as integrals over the virtual photon squared-momentum Q2. The high Q2 behavior is obtained via the operator product expansion. The low Q2 b...

本文研究了心电信号在身份识别中的应用，提出了基于快速傅里叶变换的匹配追踪心电特征提取算法。在预处理阶段，对心电信号进行消噪、标准化和质量检测等预处理，有效去除了心电信号中的噪声和心率变异所带来的干扰。特征提取阶段，对心电模板进行基于快速傅里叶变换的匹配追踪稀疏分解，原子的时频参数和投影值作为特征参数，然后构建支持向量机分类器，实现了身份识别。最后利用MIT-BIH的ST Change、PTB、QT...
Paraxial theory of sum-frequency generation by side-walk alignment and phase-matching in uniaxial crystals
non-linear optics, birefringence, sum-frequency generation
2011/9/5
A formalism in terms of Hertz potentials is presented describing sum-frequency generation in a uniaxial non-linear crystal. A scheme is proposed consisting in aligning the side-walk propagation of ext...
Influence of Phase Matching on the Cooper Minimum in Ar High Harmonic Spectra
the Cooper Minimum Harmonic Spectra
2010/11/16
We study the influence of phase matching on interference minima in high harmonic spectra. We concentrate on structures in atoms due to interference of different angular momentum channels during recom...
Spontaneous Breaking of Conformal Invariance and Trace Anomaly Matching
Conformal Invariance Trace Anomaly Matching
2010/12/22
We argue that when conformal symmetry is spontaneously broken the trace anomalies in the broken and unbroken phases are matched. This puts strong constraints on the various couplings of the dilaton. U...
Matching by solenoids in space charge dominated LEBTs
betatron matching solenoid coupling terms space charge force rotationally asymmetric
2009/9/17
The betatron matching of a rotationally asymmetric beam in space chargedominated low-energy beam transports (LEBTs) where solenoids are used forthe transverse matching has been studied. For better un...

A RELATION BETWEEN THE MATCHING NUMBER AND LAPLACIAN SPECTRUM OF A TREE
Tree Laplacian spectrum matching numbe
2007/8/7
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...
