Variational Bayesian data analysis on manifold

引用

Control Theory and Technology 2018年第3期16卷 212-220页

作者： yang ming Key Lab of Systems and Control Academy of Mathematics and Systems Science Chinese Academy of Sciences Beijing 100190 China University of Chinese Academy of Sciences Beijing 100190 China

In this paper, variational inference is studied on manifolds with certain metrics. To solve the problem, the analysis is first proposed for the variational Bayesian on Lie group, and then extended to the manifold that is approximated by Lie groups. Then the convergence of the proposed algorithm with respect to the manifold metric is proved in two iterative processes： variational Bayesian expectation （VB-F） step and variational Bayesian maximum （VB-M） step. Moreover, the effective of different metrics for Bayesian analysis is discussed.

Research of Optical Fiber Coil Winding Model Based on Large-deformation Theory of Elasticity and Its Application

引用

Chinese Journal of Aeronautics 2011年第5期24卷 640-647页

作者： JIA ming yang Gongliu School of Instrumentation Science and Opto-electronics Engineering Beihang University Beijing 100191 China

Optical fiber coil winding model is used to guide proper and high precision coil winding for fiber optic gyroscope （FOG） application. Based on the large-deformation theory of elasticity, stress analysis of optical fiber free end has been made and balance equation of infinitesimal fiber is deduced, then deformation equation is derived by substituting terminal conditions. On condition that only axial tensile force exists, approximate curve equation has been built in small angle deformation scope. The comparison of tangent point longitudinal coordinate result between theory and approximation gives constant of integration, and expression with tangent point as origin of coordinate is readjusted. Analyzing the winding parameters of an example, it is clear that the horizontal distance from the highest point of wheel to fiber tangent point has millimeter order of magnitude and significant difference with fiber tension variation, and maintains invariant when wheel radius changes. The height of tension and accurate position of tangent point are defined for proper fiber guide. For application to fiber optic gyroscope, spiral-disc winding method and nonideal deformation of straddle section are analyzed, and then spiral-disc quadrupole pattern winding method has been introduced and realized by winding system. The winding results approve that the winding model is applicable.

DISCUSSION ON MECHANISM OF CAVITATION DAMAGE ON SUPER HIGH DAMS

引用

Journal of Hydrodynamics 2000年第4期12卷 84-87页

作者： yang Zhi-ming Wuhan University of Hydraulic and Electric Engineering Wuhan 430072P.R.China

In this short paper the following viewpoints are discussed: it is possible in super high dams that the discharge flow, either in discharge tunnel or in open channel, may be an air water mixtures (two phase flow) in which the sound speed could reduce sharply depending on concentration of air, and the shock wave could be caused somewhere in super high flow while the flow velocity reaches or exceeds the sound speed in it. Besides bubble collapse, the correlation between shock wave and cavitation bubble collapse should be considered as the main mechanism of serious damage on discharge structures of super high dams.

A modified nearly analytic discrete method and wavefield simulations in transversely isotropic media

引用

Science China Earth Sciences 2005年第8期48卷 1321-1328页

作者： LU ming yang Dinghui Department of Mathematical Sciences Tsinghua University Beijing 100084 China Department of Mathematical Sciences Tsinghua University Beijing 100084 China

Nearly analytic discrete method (NADM) is a higher accurate method for elastic wave equation that can suppress effectively numerical dispersion caused by discretizing the wave equation. In this paper we investigate the efficient implementation of NADM and present a refinement of the original NADM. Our theoretical analyses show that the modified NADM can improve significantly over the original one in numerous perspectives including numerical errors, storage spaces, and computational costs. Three-component synthetic VSP seismograms in 3-layered transversely isotropic (TI) media generated by the modified NADM are also reported. Theoretical analyses and numerical results show that the modified NADM can reduce storage space about 53 percent and computational costs about 30 percent compared with the original NADM. Moreover the accuracy of the modified NADM in time increases from 2-order of the original NADM to 4-order. Numerical results suggest that the modified NADM is more suitable to large-scale modeling because the modified method has little numerical dispersions even when too-coarse grids are used.

In Silico Identification of Co-transcribed Core Cell Cycle Regulators and Transcription Factors in Arabidopsis

引用

Journal of Integrative Plant Biology 2007年第8期49卷 1253-1260页

作者： Yixing Wang ming yang Department of Botany Oklahoma State University Stillwater OK 74078 USA

Regulatory networks involving transcription factors and core cell cycle regulators are expected to play crucial roles in plant growth and development. In this report, we describe the identification of two groups of co-transcribed core cell cycle regulators and transcription factors via a two-step in silico screening. The core cell cycle regulators include TARDY ASYNCHRONOUS MEIOSIS （CYCA1;2）, CYCB1;1, CYCB2;1, CDKB1;2, and CDKB2;2 while the transcription factors include CURLY LEAF, AINTEGUMENTA, a MYB protein, two Forkhead-associated domain proteins, and a SCARECROW family protein. Promoter analysis revealed a potential web of cross- and self-regulations among the identified proteins. Because one criterion for screening for these genes is that they are predominantly transcribed in young organs but not in mature organs, these genes are likely to be particularly involved in Arabidopsis organ growth.

关键词： Arabidopsis cell cycle cyclin-dependent kinases cyclins transcription factors.
