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.","PeriodicalId":170576,"journal":{"name":"2019 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132613352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":170576,"journal":{"name":"2019 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133032231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":170576,"journal":{"name":"2019 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132762320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":170576,"journal":{"name":"2019 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123494065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
