Analysis of the convergence of a modified Weierstrass iteration(一个Weierstrass迭代修正法的收敛性分析)
为了求解多项式方程f(z)=0,我们在Weierstrass迭代的基础上给出了一个同时求解该方程所有根的迭代法,并对其收敛性及收敛的初始条件进行了分析,得出其收敛的初始条件,它仅与迭代的初始点有关而与方程的根无关,同时还证明了在此初始条件下,该迭代是3阶收敛的.

Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

ABSTRACT SnTe is considered a potential alternative to PbTe for thermoelectric applications. However, excessive carrier concentration and thermal conductivity result in poor thermoelectric performance. Herein, p‐type SnTe‐based materials Sn0.8‐xMn0.1Pb0.1SbxTe were synthesized, and the combined effects of Sb, Mn, and Pb were systematically investigated.

Complete convergence for ρ--mixing random fields(ρ--混合随机场的完全收敛性)
讨论了ρ--混合随机场的部分和完全收敛性.在一些适当的条件下,获得了较为一般的ρ--混合随机场的部分和完全收敛性定理,并得到了完全收敛速度与矩条件之间的等价关系.所得结果推广了ρ*-混合随机场和负相伴序列的相应结果.且将Hsu-Robbins型定理推广到ρ--混合随机场的情形.定理的证明基于Rosenthal型最大值不等式、Rosenthal型不等式、几个引理及缓变函数的性质.

Convergence of approximate solutions in stochastic programming(随机规划逼近解的收敛性)
本文对随机规划的逼近解的收敛性作了探讨,证明了当随机向量序列{ζ(k)(ω)}依分布收敛于ζ(ω)时,相应于ζ(k)(ω)的随机规划问题的任何最优解序列将收敛到原问题的最优解,这个结果对如何设计逼近算法提供了一个理论基础.
