Digital electronic technologies are widely used, including banking, bank operations and services as one of important sectors. Application of different types of digital technologies, including computers, computer networks, digital communication, Internet and information and communication technologies, with appropriate software, enables increasing speed, security and efficiency of all banking operations and services. It gives many benefits and advantages to the banks and to users of banking services. Way to use modern digital technologies to effectively transform classical financial data bank into digital data bank on the example of typical commercial/retail bank is proposed and described. It is also proposed organizational model of the digital bank. Advantages of using digital technologies and digital banks compared with classical banks are given.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130970934","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 realistic Zubal head phantom is used as the model and it is illuminated by 36 line sources in different scenarios to investigate the feasibility of method. The diffraction tomography based imaging methods can be confidently used only for weak scatterers. Differential data, which is obtained by measuring scattering fields in different time steps, can be treated as a weak scatterer. In addition, we have used a lossless matching medium with dielectric permittivity of 40, which not only enhances the penetration of microwaves to the brain, but also makes the measurements in far field more reliable. Reconstructed profile is extracted from differential data by solving a linear matrix system with least square method. Numerical results demonstrate that diffraction tomography can be an alternative to the previous methods with its simplicity and fast response time.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121954227","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}

However, assessing noise levels is nontrivial and there are no established tools for holistically monitoring, evaluating, managing, and planning urban noise across, e.g., a city quarter, in a qualified manner. It is the objective of an ongoing smart cities research project, “StadtLärm”, to develop a system for monitoring noise, visualizing it in 3D using spatial noise models, and automatically recognizing predefined scenes and events through classification. The system being developed is built on a platform based on the MQTT protocol. This paper discusses the system's overall and MQTT communications architecture, highlighting advantages of the approach and specific aspects of its realization.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125751366","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}
