摘要:Abstract(#br)In this paper, an iterative algorithm to approximate a common solution of a finite family of minimization problem and fixed point problem for a pair of demicontractive mappings in Hadamard spaces are proposed. Under suitable conditions, some Δ \documentclass[12p...

摘要:To test exponentiality of a population, we modify the test statistic based on the sample entropy in the literature, and establish its limiting distribution theorem under weaker conditions, which improves the existing results.(#br) * 1991 Mathematics Subject Classificat...

摘要:The Ti36Ni41Hf15Cu8 melt-spun ribbon undergoes a B2 ↔ B19' transformation upon cooling and heating. When the Ti36Ni41Hf15Cu8 melt-spun ribbon is annealed at 873 K for 1 h, the spherical (Ti, Hf)2Ni particles with a diameter of 20-40 nm precipitate in the grain interior. The ...

摘要:Consider a non-homogeneous Markov chain {Xn}n ≥ 0 to be used to estimate the global minimum of a given function f defined on S = {1, 2, …N}. We show how ergodicity results can be successfully applied to obtain the desired convergence [image omitted] where [image omitted]

摘要:Pb(Zr 0.52 T 0.48 )O 3 (PZT) thin films with different contents of rare earth europium (Eu) dopant (1 at. %-3 at. %) were fabricated on (111)Pt/Ti/SiO 2 /Si substrates by a sol-gel method with a rapid thermal process. The microstructure and ferroelectric properties such as the P-...

摘要:Abstract(#br)Let { X 1 ,..., X N } be a set of N independent random variables, and let S n be a sum of n random variables chosen without replacement from the set { X 1 ,..., X N } with equal probabilities. In this paper we give an estimate of the remainder term for the normal app...

摘要:Abstract(#br)In this paper we consider a multiple dyadic stationary process with the Walsh spectral density matrix fθ(λ), where θ is an unknown parameter vector. We define a quasi-maximum likelihood estimator % MathType!MTEF!2!1!+-% feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv...
