C-shaped split ring resonator type metamaterial antenna design using neural network
Sağık, Metin; Karaaslan, Muharrem; Ünal, Emin; Akgöl, Oğuzhan; Bakır, Mehmet; Akdoğan, Volkan; Özdemir, Ersin; Abdulkarim, Yadgar I. (SPIE, 2021)A C-shaped split ring resonator-based metamaterial (MTM) structure placed on a patch antenna is proposed. An artificial neural network (ANN) is applied to design and determine dimensions of an MTM structure that is similar ... -
Design of a fuzzy safety margin derivation system for grip force control of robotic hand in precision grasp task
İşlek, Canfer; Özdemir, Ersin (SAGE Publications, 2021)In this study, the aim was to grasp and lift an unknown object without causing any permanent change on its shape using a robotic hand. When people lift objects, they add extra force for safety above the minimum limit value ... -
Fuzzy Logic Based Sinter RDI Optimization
Beşkardeş, Ahmet; Hameş, Yakup; Çevik, Serkan; Kaya, Kemal; Özdemir, Ersin (Ieee, 2019)The RDI (Reduction Degradation Index) is an important quality criterion of sinter. In this study, a fuzzy logic based model has been developed to obtain the desired RDI value continuously. The expected RDI value for stable ... -
Mutual Coupling Reduction of Cross-Dipole Antenna for Base Stations by Using a Neural Network Approach
Özdemir, Ersin; Akgöl, Oğuzhan; Alkurt, Fatih Özkan; Karaaslan, Muharrem; Abdulkarim, Yadgar I.; Deng, Lianwen (Mdpi, 2020)In this manuscript, a resonator layer is presented for the purpose of reducing the mutual coupling effect between each antenna element of a cross dipole antenna. In design processes, an artificial neural network approach ... -
Optimizing the Gain and Directivity of a Microstrip Antenna with Metamaterial Structures by Using Artificial Neural Network Approach
Sağık, Metin; Altıntaş, Olcay; Ünal, Emin; Özdemir, Ersin; Demirci, Mustafa; Çolak, Şule; Karaaslan, Muharrem (Springer, 2021)The purpose of this study is to improve the gain and directivity of the microstrip patch antenna by means of metamaterial (MTM) structures. As it is known, antennas have power densities in a certain direction, and the ... -
Recognizing Students and Detecting Student Engagement with Real-Time Image Processing
Uçar, Mustafa Uğur; Özdemir, Ersin (MDPI, 2022)With COVID-19, formal education was interrupted in all countries and the importance of distance learning has increased. It is possible to teach any lesson with various communication tools but it is difficult to know how ...
