Conference Object Citation - Scopus: 2Machine Learning Algorithms Against Hacking Attack and Detection Success Comparison(Institute of Electrical and Electronics Engineers Inc., 2020-09-15) Yavuz, Levent; Soran, Ahmet; Onen, Ahmet; Muyeen, S. M.Power system protection units has got enormous importance with the growing risk of cyber-attacks. To create sustainable and well protected system, power system data must be healthy. For that purpose, many machine learning applications have been developed and used for bad data detection. However, each method has got different detection and application process. Methods has superiority over other methods. Although, an algorithm can detect some injections easily, same algorithm can be fail when injection type changed. So methods have got different success results when the injection types changed. For that reason, different injection types are applied on power system IEEE 14 bus system via created special hacking algorithm. PSCAD and python linkage has been used for simulation and detection parts. 3 different injection types created and applied on the system and five different most popular algorithms (SVM, k- NN, LDA, NB, LR) tested. Each algorithm's performances are compared and evaluated. © 2020 Elsevier B.V., All rights reserved.Conference Object Citation - WoS: 4Citation - Scopus: 10Sağlıkta Blokzincir Tabanlı Sistem Bilişimi Uygulamaları(Institute of Electrical and Electronics Engineers Inc., 2020-10-05) Dedeturk, Beyhan Adanur; Bakir-Güngör, Burcu; Soran, Ahmet; Adanur, BeyhanRecently, the use of blockchain technology in the field of healthcare has increased. Although blockchain technology brought several innovations to healthcare, still there are problems waiting to be resolved. In order to provide alternative solutions to these problems, the use of fog computing together with blockchain technology has been proposed. In this study, the applications of blockchain based fog computing technology in healthcare are investigated. The aim of this study is to provide the readers an idea about the interactive use of blockchain and fog computing in the field of healthcare. For this purpose, firstly, fog computing and blockchain technologies are introduced. Afterwards, the integration of these areas, the advantages and disadvantages of using these technologies in the field of healthcare is discussed and a new system architecture is proposed. © 2021 Elsevier B.V., All rights reserved.Conference Object Citation - Scopus: 1Blokzincir Tabanlı Kullanıcı Yönetim Sistemi(Institute of Electrical and Electronics Engineers Inc., 2020-10-05) Temiz, Mustafa; Soran, Ahmet; Arslan, Halil; Erel, HilalBlockchain is a reliable and transparent structure formed by distributing the data in blocks connected to each other using various cryptography techniques to other points on the network. The difference from the existing database operations is that the authorities and responsibilities do not exist in a single central authority, and that these powers and responsibilities are distributed to the other nodes in the network and the assignment is shared. To provide this, peer to peer network infrastructure is used. However, at this stage, authentication in terms of security is one of the basic security mechanisms. In this study, a user management system which can be integrated with more reliable and current technologies, which is thought to be the solution to speed problems in blockchain, is proposed. © 2021 Elsevier B.V., All rights reserved.
