Crown shaped edge multiband antenna design for 5G and X-Band applications
Hakanoglu, Baris Gurcan; Kilic, Veli Tayfun; Altindis, Fatih; Turkmen, Mustafa (SPRINGER, 2023)Nowadays we are experiencing the fifth-generation (5G) technology with new frequency bands to achieve high broadband speed, minimum latency and more developed end user devices. Due to the different frequency ranges for ... -
Detection of Epileptic Seizures with Tangent Space Mapping Features of EEG Signals
Altındiş, Fatih; Yılmaz, Bülent (Institute of Electrical and Electronics Engineers Inc., 2021)Detection of epileptic seizures from EEG signals is well-studied topic for the last couple of decades. Lately, automated signal processing and machine learning methods were developed to detect epileptic seizures. However, ... -
Feature Extraction and Classification in A Two-State Brain-Computer Interface
Altindis, Fatih; Yilmaz, Bulent (IEEE, 2015)Brain Computer Interface (BCI) technology is used to help patients who do not have control over motor neurons such as ALS or paralyzed patients, to communicate with outer world. This work aims to classify motor imageries ... -
Parameter investigation of topological data analysis for EEG signals
Altindis, Fatih; Yilmaz, Bulent; Borisenok, Sergey; Icoz, Kutay (ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 01.01.2021)Topological data analysis (TDA) methods have become appealing in EEG signal processing, because they may help the scientists explore new features of complex and large amount of data by simplifying the process from a ... -
Prediction of preference and effect of music on preference: a preliminary study on electroencephalography from young women
Yilmaz, Bulent; Gazeloglu, Cengiz; Altindis, Fatih (TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, ATATURK BULVARI NO 221, KAVAKLIDERE, ANKARA, 00000, TURKEY, 2019)Neuromarketing is the application of the neuroscientific approaches to analyze and understand economically relevant behavior. In this study, the effect of loud and rhythmic music in a sample neuromarketing setup is ... -
