Additive skew G-codes over finite fields
Dougherty, S. T.; Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz (Springer Link, 2023)We define additive skew G-codes over finite fields and discuss several dualities attached to these codes. We examine the properties of self-dual skew G-codes and in particular we show that the dual, under any duality, of ... -
An application of a virus optimization algorithm to the problem of computing binary self-dual and LCD codes
Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz (American Institute of Mathematical Sciences (AIMS), 2022)In this paper, we employ a virus optimization (VO) algorithm, which is one of the metaheuristic optimization techniques, and a known construction method to compute many new binary [72, 36, 12] self-dual codes and ... -
Combustion characteristics of trimethyl borate, diesel, and trimethyl borate-diesel blend droplets
Yontar, Ahmet Alper; Özgüner, Ayşe Gizem; Adıgüzel, Mehmet Ali; Üstün, Deniz (Elsevier, 2022)In this study, droplet tests were carried out for pure and blended forms of diesel fuel, which is the traditional fuel, and trimethyl borate fuel, which is new generation fuels. In this context, the evolution of fuel droplet ... -
Construction of DNA Codes From Composite Matrices and a Bio-Inspired Optimization Algorithm
Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz; Dougherty, S. T. (IEEE-INST Electrical Electronics Engineers Inc., 2023)Indexed keywords SciVal Topics Metrics Funding details Abstract In this work, we present a new construction method for reversible codes. We employ composite matrices derived from group rings and show how to ... -
Designing of the Artificial Neural Network Model Trained by Using the Different Learning Algorithms to Classify the Electrocardiographic Signals
Çelik, İbrahim; Üstün, Deniz; Akdağlı, Ali (European Journal of Science and Technology, 2022)An artificial neural network model trained by using various learning algorithms is designed to classify the electrocardiographic signals in this study. The model of artificial neural network is constructed on the structure ... -
Dihedral codes with 1-dimensional hulls and 1-dimensional linear complementary pairs of dihedral codes
Dougherty, S. T.; Sahinkaya, Serap; Üstün, Deniz (Springer Link, 2023)In this paper, we study dihedral codes with 1-dimensional hulls and we determine precisely when dihedral codes over fnite felds with 1-dimensional hulls exist. Moreover, we show that these codes come canonically in pairs. ... -
DNA Codes From Reversible Group Codes By A Virus Optimisation Algorithm
Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz (2023)In this paper, we employ group rings and some known results on group codes to study reversible group DNA codes. We define and study reversible cyclic DNA codes from a group ring point of view and we also introduce the ... -
DNA codes from skew dihedral group ring
Dougherty, S. T.; Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz (American Institute of Mathematical Sciences (AIMS), 2022)In this work, we present a matrix construction for reversible codes derived from skew dihedral group rings. By employing this matrix construction, the ring Fj,k and its associated Gray maps, we show how one can construct ... -
Group matrix ring codes and constructions of self-dual codes
Dougherty, S. T.; Korban, Adrian; Şahinkaya, Serap; Üstün, Deniz (Springer Link, 2023)In this work, we study codes generated by elements that come from group matrix rings. We present a matrix construction which we use to generate codes in two different ambient spaces: the matrix ring M-k(R) and the ring R, ... -
Investigation of combustion characteristics on triethyl borate, trimethyl borate, diesel, and gasoline droplets
Değirmenci, Hüseyin; Yontar, Ahmet Alper; Sofuoğlu, Duygu; Değirmenci, Hüseyin; Ayaz, Tahir; Üstün, Deniz (Pergamon Elsevier Science Ltd., 2023)In this study, the evolution of fuel droplet diameter, flame structure, and maximum flame temperature over time was observed using a high-speed camera and a thermal camera at the same time. Traditional fuels (diesel and ... -
New Type I Binary [72,36,12] Self-Dual Codes From Composite Matrices And R-1 Lifts
Korban, Adrian; Sahinkaya, Serap; Üstün, Deniz (American Institute of Mathematical Sciences (AIMS), 2023)In this work, we define three composite matrices derived from group rings. We employ these composite matrices to create generator matrices of the form [In | Ω(v)], where In is the identity matrix and Ω(v) is a composite ... -

Dougherty, S. T.; Sahinkaya, Serap; Üstün, Deniz (Springer Link, 2023)This paper presents an image encryption algorithm by using time signature-dependent S-Boxes, which are based on Latin squares, the Playfair system of cryptography, and functions that are inspired by the behavior of a ... -
An optimized surrogate model using differential evolution algorithm for computing parameters of antennas
Üstün, Deniz; Toktaş, Feyza; Toktaş, Abdurrahim (Wiley, 2022)In this study, a method based on surrogate model (SM) for computational analysis of antenna parameters such as the resonant frequency (RF) and bandwidth (BW) is presented. Moreover, it is attempted to optimize the SM using ... -
Parameter optimization of chaotic system using Pareto-based triple objective artificial bee colony algorithm
Toktaş, Abdurrahim; Erkan, Uğur; Üstün, Deniz; Wang, Xingyuan (Springer London Ltd, 2023)Chaotic map is a kind of discrete chaotic system. The existing chaotic maps suffer from optimal parameters in terms of chaos measurements. In this study, a novel approach of optimization of parametric chaotic map (PCM) ...
