Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：t-stabilities and t-structures for the weighted projective line of type (2)
加权投影线 t-稳定性 t-结构
2023/11/13
We focus on the study of t-stabilities on a triangulated category in the sense of Gorodentsev, Kuleshov and Rudakov. We give an equivalent description for the nest t-stabilities on certain triangulate...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Large deviations principle for weighted means of a recursive numerical method for ergodic SDEs
遍历 SDE递归 数值方法 加权均值 大偏差原理
2023/4/24
For ergodic SDEs, their ergodic limits are usually approximated by the suitable means of numerical methods. To reveal the numerical asymptotic behavior, we study the large deviations principle (LDP) f...
RESOLUTION ENHANCEMENT ALGORITHM FOR SPACEBORN SAR BASED ON HANNING FUNCTION WEIGHTED SIDELOBE SUPPRESSION
SAR image Sidelobe suppression Hunning function
2018/5/14
Resolution and sidelobe are mutual restrict for SAR image. Usually sidelobe suppression is based on resolution reduction. This paper provide a method for resolution enchancement using sidelobe opposit...

Weighted Estimation of the Dependence Function for an Extreme-Value Distribution
Bivariate extreme dependence function jackknife empirical likeli- hood method
2016/1/19
Bivariate extreme-value distributions have been employed in modeling extremes in environmental sciences and risk management. An important issue is to estimate the dependence function such as Pickands ...
Smoothed weighted empirical likelihood ratio confidence intervals for quantiles
bootstrap doubly censored data empirical likelihood interval censored data partly interval censored data right censored data
2015/12/11
Thus far, likelihood-based interval estimates for quantiles have not been studied in the literature on interval censored case 2 data and partly interval censored data, and, in this context, the use of...
The dual weighted residual (DWR) method yields reliable a posteriori error bounds for
linear output functionals provided that the error incurred by the numerical approximation of the
dual solution i...
Gabor Analysis in Weighted Amalgam Spaces
Amalgam spaces frames Gabor expansions Gabor frames modulation spaces phase-space sampling time-frequency analysis Walnut representation
2015/12/10
Gabor frames {e2πinβ·xg(x − kα)}n,k∈Zd provide series representations not only of functions in L2(Rd) but of the entire range of spaces Mν p,q known as the modulation spaces. Membership of a fun...

2015/12/10
In this paper we give a sharp estimate on the norm of the scaling operator Uλf(x) = f(λx) acting on the weighted modulation spaces Mp,q s,t (Rd). In particular, we recover and extend recent results by...

THE MODULI SPACE OF WEIGHTED CONFIGURA TIONS ON PROJECTIVE SPACE.
This paper introduces some notions of e ective dimension for weighted
function spaces. A space has low e ective dimension if the smallest ball
in it that contains a function of variance 1, has no fu...
Given data from a spherical Gaussian distribution with unknown mean
vector θ, estimates of quadratic functionals are constructed by thresholding. Mean
squared error bounds are derived via a comparis...
ESTIMATION OF GRASS YIELD IN LARGE REGION ON GEOGRAPHICALLY WEIGHTED REGRESSION MODEL
Geographically Weighted Regression (GWR) Model Grass Yield
2015/5/6
The grass yield embodies its productivity，and also is ground for developing animal husbandry production management. Now the remote sensing technology has been becoming an efficient and feasible mean...
Inequality for Variance of Weighted Sum of Correlated Random Variables
Variance Covariance Random Variable Chebyshev!ˉs Inequality Correlated Random Variable Positive Semidefinite Matrix Law of Large Numbers
2012/11/23
The upper bound inequality for variance of weighted sum of correlated random variables is derived according to Cauchy-Schwarz's inequality, while the weights are non-negative with sum of 1. We also gi...

2012/8/8
We shall establish a discrete weighted Helmholtz decomposition in edge element
spaces, which is stable uniformly with respect to the jumps in the discontinuous weight
function. The stable decomposit...
