A Chaotic System with Infinite Equilibria and Its S-Box Constructing Application

Xiong Wang; Akif; Çavuşoğlu, Ünal (MDPI, 2018)

Systems with many equilibrium points have attracted considerable interest recently. A chaotic system with a line equilibrium has been studied in this work. The system has infinite equilibria and exhibits coexisting chaotic ...
A New Chaotic System with Multiple Attractors: Dynamic Analysis, Circuit Realization and S-Box Design

Qiang Lai; Akif Akgul; Chunbiao Li; Guanghui Xu; Çavuşoğlu, Ünal (MDPI AG, 2018)

This paper reports about a novel three-dimensional chaotic system with three nonlinearities. The system has one stable equilibrium, two stable equilibria and one saddle node, two saddle foci and one saddle node for different ...
A new SNMP-based algorithm for network traffic balancing in virtual local area networks

Serdar Kirisoglu; Resul Kara; Özçelik, İbrahim (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2019)

Virtual local area network (VLAN). s are being created for improve performance, easy to manage security and ensure address on local area networks. This paper introduces a new approach for load balancing on virtual local ...
A proposal of SDN based VANET architecture for urban intersection management

Balta, Musa; Özçelik, İbrahim (GAZI UNIV, FAC ENGINEERING ARCHITECTURE, 2019)

One of the main challenges for developed cities is vehicle traffic management. There are many studies about urban intersection managements both in literature and in practice. In recent years, VANET (Vehicular ad hoc networks) ...
A study on application container resource efficiency

Ozmen Emre Demirkol; Öz, Cemil; Arkin Demirkol (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2019)

Nowadays, the IT service environment develops in a dynamic, rapid, and unpredictable way. Microservices and application containers in this process have a significant impact on new generation IT service models. The fact ...
Analysis of Machine Learning Methods in EtherCAT-Based Anomaly Detection

Ovaz Akpınar, Kevser; Özçelik, İbrahim (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)

Today, the use of Ethernet-based protocols in industrial control systems (ICS) communications has led to the emergence of attacks based on information technology (IT) on supervisory control and data acquisition systems. ...
Artificial immune system based wastewater parameter estimation

Cengiz Sertkaya; Yurtay, Nilüfer (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2018)

The basis of a wastewater treatment system is to achieve the desired characteristics of the wastewater treatment process. An estimation of the obtained wastewater treatment characteristics provides the information needed ...
Development of the ECAT Preprocessor with the Trust Communication Approach

Ovaz Akpınar, Kevser; Özçelik, İbrahim (WILEY-HINDAWI, 2018)

In the past several years, attacks over industrial control systems (ICS) have become increasingly frequent and sophisticated. The most common objectives of these types of attacks are controlling/monitoring the physical ...
Development of the ECAT Preprocessor with the Trust Communication Approach (vol 2018, 2639750, 2018)

Ovaz Akpınar, Kevser; Özçelik, İbrahim (WILEY-HINDAWI, 2019)
S-Box Based Image Encryption Application Using a Chaotic System without Equilibrium

Xiong Wang; Çavuşoğlu, Ünal; Sezgin Kacar; Akgül, Akif (MDPI, 2019)

Chaotic systems without equilibrium are of interest because they are the systems with hidden attractors. A nonequilibrium system with chaos is introduced in this work. Chaotic behavior of the system is verified by phase ...
