A new chaotic system with hidden attractor and its engineering applications: analog circuit realization and image encryption

Çavuşoğlu, Ünal; Shirin Panahi; Akgül, Akif; Sajad Jafari; Sezgin Kacar (SPRINGER, 2019)

In this article a simple chaotic flow with hidden attractor is proposed. Various dynamics of this new system such as periodic and chaotic oscillations can be achieved by setting bifurcation parameters in a proper value. ...
A new hybrid approach for intrusion detection using machine learning methods

Çavuşoğlu, Ünal (SPRINGER, 2019)

In this study, a hybrid and layered Intrusion Detection System (IDS) is proposed that uses a combination of different machine learning and feature selection techniques to provide high performance intrusion detection in ...
A Novel Chaotic System With Boomerang-Shaped Equilibrium, Its Circuit Implementation and Application to Sound Encryption

Saleh Mobayen; Sundarapandian Vaidyanathan; Aceng Sambas; Sezgin Kacar; Çavuşoğlu, Ünal (SPRINGER INTERNATIONAL PUBLISHING AG, 2019)

In the chaos literature, there has been much attention paid to chaotic systems with uncountable equilibrium points such as systems with line equilibrium, curve equilibrium. This paper reports a 3-D chaotic system with a ...
A NOVEL S-BOX DESIGN ALGORITHM AND FUZZY-PID CONTROLLER DESIGN FOR A 5-D BURKE-SHAW SYSTEM WITH HIDDEN HYPERCHAOS

Qingxia Ma; Wenqiang Luo; Hadi Jahanshahi; Çavuşoğlu, Ünal; Kif Akgul; Xianguang Lin (ACTA PRESS, 2019)

This paper presents a new S-Box design algorithm of hidden hyperchaos in a 5-D hyperchaotic Burke-Shaw system, which is obtained by adding feedback controllers to the classic Burke-Shaw system. Of particular interest is ...
A software tool development study for solar energy potential analysis

Kaynak, Sümeyye; Kaynak, Baran; Özmen, Ahmet (ELSEVIER SCIENCE SA, 2018)

Analysis of solar radiation on buildings at the urban or individual scale has an important share in the formation of a sustainable environment. The accuracy of solar radiation analysis in buildings depends on the holistic ...
Deep learning approaches in electron microscopy imaging for mitochondria segmentation

Öztel, İsmail; Yolcu Öztel, Gözde; Ilker Ersoy; Tommi A. White; Filiz Bunyak (INDERSCIENCE ENTERPRISES LTD, 2018)

Deep neural networks provide outstanding classification and detection accuracy in biomedical imaging applications. We present a study for mitochondria segmentation in electron microscopy (EM) images. Mitochondria play a ...
Determination of the Gas Density in Binary Gas Mixtures Using Multivariate Data Analysis

Adak, Muhammed Fatih; Akpınar, Mustafa; Yumuşak, Nejat (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2017)

Some solvents in commercial products may have harmful effects on human health. It is important to determine the percentage of this certain solvent in a product to detect any possible health hazards. In this paper, three ...
GPU-Based Dynamic Solar Potential Estimation Tool Using 3D Plans

; Kaynak, Sümeyye; Kaynak, Baran; Özmen, Ahmet (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2020)

Estimations of the solar potential from the building design files may affect placement considerations in favor of more sunlight reception that reduces the energy costs and saves the environment. In this study, a GPU based ...
LIBRARY AUTOMATION DESIGN FOR VISUALLY IMPAIRED PEOPLE

Yurtay, Nilüfer; Yücel Bicil; Sait Çelebi; Çit, Gülüzar; Balta, Deniz (TURKISH ONLINE JOURNAL EDUCATIONAL TECH-TOJET, 2011)

Speech synthesis is a technology used in many different areas in computer science. This technology can bring a solution to reading activity of visually impaired people due to its text to speech conversion. Based on this ...
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 ...
