Görüntü Bölütleme Yöntemlerinin Karşilaştirilmasi
(Institute of Electrical and Electronics Engineers Inc., 2019)
Image segmentation is an important image processing method. The segmentation method, which is a process of dividing into different regions, is a meaningful according to certain features of the image. In this paper, histogram ...
Assessment of CSP-based two-stage channel selection approach and local transformation-based feature extraction for classification of motor imagery/movement EEG data
(De Gruyter, 2019)
The main idea of brain-computer interfaces (BCIs) is to facilitate the lives of patients having difficulties to move their muscles due to a disorder of their motor nervous systems but healthy cognitive functions. BCIs are ...
Antioxidant activity of the aqueous extract of Iris taochia and identification of its chemical constituents
(OMICS International, 2018)
In this study, phytochemical components and antioxidant capacity of extracts obtained from Iris taochia plant, which is endemic to Caucasus, were investigated. Fifteen new compounds were detected and identified using a ...
Effect of non-Gaussian noise and primary user traffic on detection performance in cognitive radio [Bilissel Radyoda Gauss Olmayan Gürültünün ve Birincil Kullanici Trafi?inin Algilama B?sarimina Etkisi]
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this study, for channels containing primary user traffic, we investigate how non-Gaussian noise model affects detection performance in cognitive radio. As decision statistic, energy detector has been preferred by ...
Performance analysis of rule based automatic SNN algorithm on big data sets [Kural tabanli otomatik SNN algoritmasinin büyük veri setleri üzerindeki performans incelemesi]
(Institute of Electrical and Electronics Engineers Inc., 2018)
Clustering is defined as the classification of patterns into groups (clusters) without supervision. The clustering of similarities of data is a complex process that can not be done with human hands. There are various ...
Convolution kernel size effect on convolutional neural network in histopathological image processing applications
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this study, the change in the classification success of the convolutional neural network (CNN) is investigated when the dimensions of the convolution window are altered. For this purpose, four different linear convolution ...
Weighting and classification of image features using optimization algorithms
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this study, importance ratios of features extracted from images using feature extraction algorithms are examined. A significance coefficient is determined for each feature parameter. The number of features is reduced ...
A new pseudo random number generator based on Chebyshev maps and parameter switching
(Institute of Electrical and Electronics Engineers Inc., 2018)
Digital implementations of chaotic systems are periodic and they are degraded versions of the original chaotic system. Hence, all digital pseudo random number generators based on chaotic systems inherently contain several ...
Phytochemical screening and in-vitro antioxidant, antimicrobial activity and DNA interaction of Leucojum aestivum
(Parlar Scientific Publications, 2018)
The aim of this study was evaluation of invitro antioxidant and antimicrobial activities of Leucojum aestivum extracts, and determination of the total phenolic compounds of Leucojum aestivum by reverse-phase high-performance ...
Prevalence and characteristics of coronary artery anomalies using invasive coronary angiography in 6237 consecutive patients in a single center in Turkey
(Academy of Medical Sciences of I.R. Iran, 2018)
Background: Coronary artery anomalies (CAAs) include clinically and anatomically diverse types of congenital heart defects occurring in a complicated spectrum. The aim of the present study is to describe congenital anomalies ...
