Airy elegant Gaussian beam is the airy beam which is modulated by the elegant Gaussian. According to the (2+1)D paraxial wave equation describing the wave propagation of the electric field, Airy elegant Gaussian solution to the paraxial wave equation in spatial field are accessed. The solution of the Airy-Elegant-Largeurre-Gaussian(AiELG) beam, which is the spatiotemporal Airy elegant Gaussian beam modulated by the elegant Larguerre function, can be accessed by solving the (3+1)D Schrödinger equation in the free space. We found that their intensity profiles are determined by three parameters: the azimuthal mode number, the radial mode number and the modulation depth. It is worth mentioning that the radial mode number of AiELG wave packet will change in propagation.

Switches and crossings (S&Cs) are one of the vital subsystems in railway. The main function of an S&C is to help trains to safely move from one track to another track. To do this, an S&C consists of movable and fixed mechanical parts, as well as signaling and electrical systems. Each of these systems requires a proper maintenance and is susceptible to failures which ultimately lead to train disturbances. The aim of the paper is to carry out life cycle cost analysis for railway S&C which operate over more 40 years. We decompose the life cycle of the S&C and break down them into subsystems to identify which of them requires maintenance. We demonstrated how to decide optimal S&C through cost identification and system breakdown.

In this paper, considered approaches to obtaining Z-solutions of a multicriterial problem to obtain a sustainable solution it is desirable to have additional a priori information on the degree of preference for a particular goal, which is specified by various fuzzy operators. A set of fuzzy sets corresponding to various properties of the object of investigation, in particular, qualitative (linguistic) and quantitative information about the characteristics of the object is determined. Proposed the Z-numbers approach to the prediction problem as a multicriterial problem, which reduces to some combination of fuzzy selection criteria, and to the study of complex systems as a hierarchical structure, since in order to obtain a scientifically based forecast, it is often necessary to attract information from social and natural sciences, in which the apparatus of fuzzy sets and Z-numbers is also preferable.

We develop and analyze mean-variance efficient portfolios. Each portfolio comes as a solution of an optimization problem, which approximates the expected value of a utility function. The approximation is an upper bound on the expected value of the utility function. The bound is based on the first two probability moments and cross-moments of the portfolio”s random return. We prove that the optimal solution of the approximate optimization problem yields a mean-variance efficient portfolio. We illustrate how to use the resulting portfolio in practice by designing a daily trading strategy with stocks traded on the New York Stock Exchange (NYSE). The approximate optimization model is solved once every day. Out-of-sample numerical results are presented for 27 years of daily trading for 24 stocks from NYSE.
