Medical Technologies National Conference, TIPTEKNO 2015 -- 15 October 2015 through 18 October 2015, The aim of this study is to observe the impact on the emotional evaluation of luminance, which is a perceptual feature of visual stimuli from electroencefelography (EEG) data recorded. EEG recordings obtained from 13 healthy individuals in the 25-45 age range were used in the study. Features obtained analysis of these records with Short Time Fourier Transform (STFT) are evaluated by statistically. The increase in the luminance level of the neutral visual stimuli as a result of statistical findings are reflected in the EEG activity, when given a bright neutral visual stimuli, comparable rates of exchange between the first 0-200 ms and 200-400ms on the electrical activity in the brain across the bright neutral stimuli to be higher than originally neutral stimulus were observed. This study has an initial research on the issue. In the following study, the difference in luminance level which regions of the brain, frequency and time, it will try to determine what caused the change. © 2015 IEEE.

Electric Electronics, Computer Science, Biomedical Engineerings Meeting, EBBT 2016 -- 26 April 2016 through 27 April 2016, The aim of this study is to investigate the relationship between the emotional evaluation and luminance over the P300 compenent observed on EEG records. EEG recordings obtained from 13 healthy individuals were used in the study. Features were obtained using wigner ville distribution (WVD) of these records. According to 'accuracy percentage' performance results that the analysis of the obtained features, 92.3% of individual's values in the feature vector obtained from EEG data base of neutral visual stimule in BRIGHT data group to be greater than the ORIGINAL data group were found. The results of studies on the subject of electrophysiology is considered an important parameter that can include methods such as luminance. © 2016 IEEE.

2013 21st Signal Processing and Communications Applications Conference, SIU 2013 -- 24 April 2013 through 26 April 2013 -- Haspolat, As one of the renewable energy sources, wind energy has received great attention in Turkey as in the rest of the world in t he last decade. Despite o f t his t rend, t here is an increasing number of assessment reports stating the impact of wind farms on the performance degradation of electromagnetic propagation systems. In this paper, wind turbines' effects on radar detection performance are investigated using radar data which we constructed using a real terrain scenario and two dimensional propagation analysis employing different numerical electromagnetic techniques. © 2013 IEEE.
