The total hadron multiplicity and the multiplicity in the three-jet events ine + e ?-annihilation are considered. The formula for the total multiplicity (with account for the heavy quark contribution) agrees well with experiment. The value of the multiplicity for three-jet events is predicted. 相似文献

On differential stability in stochastic programming 总被引:2,自引:0,他引:2
Alexander Shapiro 《Mathematical Programming》1990,47(1-3):107-116
In this paper optimal solutions of a stochastic programming problem are considered as functions of the underlying probability distribution. Their directional derivatives, in the sense of Gâteaux, are calculated by applying some recent results from the sensitivity analysis of nonlinear programs. These derivatives are employed as a heuristic device in order to derive the asymptotic distribution of statistical estimators of the optimal solutions. 相似文献

The vast size of real world stochastic programming instances requires sampling to make them practically solvable. In this
paper we extend the understanding of how sampling affects the solution quality of multistage stochastic programming problems.
We present a new heuristic for determining good feasible solutions for a multistage decision problem. For power and log-utility
functions we address the question of how tree structures, number of stages, number of outcomes and number of assets affect
the solution quality. We also present a new method for evaluating the quality of first stage decisions. 相似文献

Electrochemical activity and morphology of human erythrocytes at optically transparent ITO electrode
A. Yu. Tsivadze M. Sh. Khubutiya A. K. Evseev I. V. Goroncharovskaya N. V. Borovkova A. I. Shapiro O. V. Batishchev M. M. Goldin 《Doklady Physical Chemistry》2017,477(1):201-204
The electrochemical activity of a suspension of human erythrocytes was found at potentials above +0.4 V. The limiting current of electrooxidation was found to linearly depend on the cell concentration in the suspension. The electrochemical activity of an erythrocyte suspension is accompanied by reversible changes in the cell morphology only in non-buffered media. 相似文献

An asymptotic model of the flow in the laminar boundary layer of a gas-evaporating droplet mixture is constructed within the framework of the two-continuum approximation. The case of evaporation of the droplets into an atmosphere of their own vapor is examined in detail with reference to the example of longitudinal flow over a hot flat plate. Numerical and asymptotic solutions of the boundary layer equations constructed are found for a number of limiting situations (low droplet concentration, no droplet deposition, significant droplet deposition). The development of the flow with respect to the longitudinal coordinate is studied and it is shown that in the absence of droplet deposition a region of pure vapor may be formed near the surface. Similarity criteria are established and the mechanism of surface heat transfer enhancement is studied for a low evaporating droplet concentration in the boundary layer. In the inertial deposition regime the results of calculating the integral heat transfer coefficient are found to correspond with the experimental data [1].Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No.3, pp. 42–50, May–June, 1992. 相似文献

The block mechanism of the formation of J-aggregates from the dimers of various dyes in an aqueous solution under the action
of the multiply charged Eu+3 cation was considered for the first time. It was shown that the structure and the position of the absorption maximum of the
mixed J-aggregates are determined by the length of the dye chromophore moiety. It was concluded that the mixed J-aggregates
are of interest as nanosized optical elements with varying optical and electronic properties depending on the structure of
cyanines used. 相似文献
