The uniqueness theorem for generalized solutions of initial-boundary problems for the Marguerre—Vlasov vibrations of shallow
shells with clamped boundary conditions is proved. A unique method developed by the author, based upon a nonstandard treatment
of smoothing operators, is applied instead of using an enclosure theorem at the critical values of indices.

Tails of distributions having the form of the geometric convolution are considered. In the case of light-tailed summands,
a simple proof of the famous Cramér asymptotic formula is given via the change of probability measure. Some related results
are obtained, namely, bounds of the tails of geometric convolutions, expressions for the distribution of the 1st failure time
and failure rate in regenerative systems, and others. In the case of heavy-tailed summands, two-sided bounds of the tail of
the geometric convolution are given in the cases where the summands have either Pareto or Weibull distributions. The results
obtained have the property that the corresponding lower and upper bounds are tailed-equivalent.

The constant stepsize analog of Gelfand–Mitter type discrete-time stochastic recursive algorithms is shown to track an associated stochastic differential equation in the strong sense, i.e., with respect to an appropriate divergence measure. 相似文献

Motivated by many problems in optimization and control, this paper is concerned with singularly perturbed systems involving both diffusions and pure jump processes. Two models are treated. In the first model, the jump process changes very rapidly by comparison with the diffusion processes. In the second model, the diffusions change rapidly in comparison with the jump process. Asymptotic expansions are developed for the transition density vectors via a constructive method; justification of the asymptotic expansions and analysis of the remainders are provided. 相似文献

Evaluation for the performance of learning algorithm has been the main thread of theoretical research of machine learning.
The performance of the regularized regression algorithm based on independent and identically distributed(i.i.d.) samples has
been researched by a large number of references. In the present paper we provide the convergence rates for the performance
of regularized regression based on the inputs of p-order Markov chains. 相似文献

In this paper we generalize the notion of essential codimension of Brown, Douglas, and Fillmore using KK-theory and prove a result which asserts that there is a unitary of the form ‘identity + compact’ which gives the unitary equivalence of two projections if the ‘essential codimension’ of two projections vanishes for certain C∗-algebras employing the proper asymptotic unitary equivalence of KK-theory found by M. Dadarlat and S. Eilers. We also apply our result to study the projections in the corona algebra of C(X)⊗B where X is [0,1], (−∞,∞), [0,∞), and [0,1]/{0,1}. 相似文献

In this article we have studied the peristaltic motion of an incompressible Williamson fluid with constant and radially varying magnetohydrodynamics (MHD) in an endoscope. Using the low Reynolds and long wavelength assumptions, the equations of Williamson fluid model in simplified form are solved using (i) the HAM method and (ii) the Shooting method. The comparisons of both solutions have been found a very good agreement. Graphical results have been presented for various emerging parameters. © British Crown Copyright 2010/MOD.
