56. pointwise boundary $\bm{{C}^{1,\alpha}}$ Estimates for some degenerate fully nonlinear elliptic equations on $\bm{C^{1,\alpha}}$ Domains

Author

Li, Xuemei and Li, Dongsheng

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, we establish pointwise boundary ${{C}^{1,\alpha}}$ estimates for viscosity solutions of some degenerate fully nonlinear elliptic equations on ${C^{1,\alpha}}$ domains. Instead of straightening out the boundary, we utilize the perturbation and compactness techniques., Comment: 10 pages

Abstract

In this paper, we show the nondegeneracy of positive bubble solutions for generalized energy-critical Hartree equations (NLH) \begin{equation*} -{\Delta u}\sts{x} -{\bm\alpha}\sts{N,\lambda} \int_{\R^N} { \frac{ u^{p}\sts{y}}{\pabs{\,x-y\,}{\lambda}} }\diff{y}\, u^{p-1}\sts{x} =0,\quad x\in \R^N \end{equation*} where $N\geq 3$, $0<\lambda

65. The address matching method of malfunction service worksheet of power customers based on standard address base

Author

Xu Xin, Fu Jun, Sun Zhijie, and Li Xuemei

Subjects
Engineering (General). Civil engineering (General), TA1-2040
Abstract

Processing methods stay at the manual processing level, which is inefficient. By analyzing the address of 95598 worksheet of power customers, a standard address base structure and matching rules for storing standard data sets are established, and a matching method of 95598 incident worksheet of power customers based on standard address base is proposed. Drawing on the segment of standard address base, the method also defines the maximum length of the forward matching algorithm and can match along the self-defined address matching rules. It reduces the number of matches between the address to be matched and the standard data set, decreases the target data set used in the next participle, and improves the matching efficiency. In addition, by defining ambiguous addresses and expanding the rule tree, the matching success rate of the addresses to be matched and the flexibility of system implementation are improved

66. Research on phase transition and strength under ramp compression with graded density impactor

Author

Tan Ye, Li Xuemei, Yu Yuying, and Jin Ke

Subjects
Physics, QC1-999
Abstract

In our work, graded density impactors fabricated from 8 to 40 layers, are specifically designed to generate desired strain rates (on the order of 105~106 s-1) and thermodynamic path(shock loading-ramp loading-release). And experiments on phase transition and strength for metals (bismuth, LY12 Al) have been performed with light gas gun to peak pressure between 30 GPa and 50 GPa. Particle velocity at sample/window interface in these experiments are simultaneously traced by a distance interferometer system for any reflector, and a wave profile analysis is employed to explore the solidification transition and strength behaviour along elevated isentrope.

99. ${W}^{2,p}$ Estimates for Elliptic Equations on $C^{1,\alpha}$ Domains

Author

Li, Dongsheng, Li, Xuemei, and Zhang, Kai

Subjects
Mathematics - Analysis of PDEs
Abstract

In this paper, a new method is represented to investigate boundary $W^{2,p}$ estimates for elliptic equations, which is, roughly speaking, to derive boundary $W^{2,p}$ estimates from interior $W^{2,p}$ estimates by Whitney decomposition. Using it, $W^{2,p}$ estimates on $C^{1,\alpha}$ domains are obtained for nondivergence form linear elliptic equations and further more, fully nonlinear elliptic equations are also considered., Comment: 17 pages
