No full text2019 Scientific Meeting on Electrical-Electronics and Biomedical Engineering and Computer Science, EBBT 2019 -- 24 April 2019 through 26 April 2019 --#nofulltext# --- Atasoy, Mehmet Berkay (Arel Author), Birankar, Eyüp (Arel Author), Arıca, Şafak Abdullah (Arel Author), Duru, Dilek Göksel (Arel Author)In this study, it was aimed to classify the electrical signals recorded from human brain during different season (summer-winter) videos as stimuli. Data have been recorded using 14 channels EEG from four male participants. The power of delta, theta, alpha, beta and gamma frequency bands have been recorded and used to classify the collected data. Decision tree pre-processing method have been used to select the attributes of frequency bands and electrodes. To classify the data, support vector machines (SVM), linear discriminant analysis (LDA) and logistic regression (LR) machine learning algorithms have been used. It was found that it was separated %82.25 with SVM, %81 with LDA and %80.75 with LR. The results of three algorithms have shown similar scores. © 2019 IEEE
The Plight of Marginalized Women in Khaled Hosseini’s a Thousand Splendid Suns in ‘The Third World Feminism’
Get PDFThird World Feminism’ investigates into the resistance and portrayal of women in literature in the oppressive and marginalizing territories. Postcolonial feminism highlights a tendency towards universalizing women by focusing on the involvement of women in the Western lifestyle in the war-stricken lands where they have been, on the one hand, segregated as inferior; yet, on the other hand, upheld as the instigators of resistance towards the betterment of societies in which the full impact of a misguided patriarchal rule breaks the women down emotionally, who are abused, deceived and controlled. Thus, this paper aims at displaying the observations considering local culture, gender discrimination and female passive resistance as far as collected from Khaled Hosseini’s A Thousand Splendid Suns. The novel depicts the conflicts of identification of the women which pave the way for the degradation applied on the characters. Subsequently, from a postcolonial feministic perspective, the paper attempts to investigate the plights of women, which are enforced on them through the patriarchal components and standards of culture

Characterisation and comparison of disc brake pads of heavy vehicles by experimental methods
No full textIn this study, characteristics of disc brake pads of heavy vehicles produced by three different manufacturers were compared experimentally. The former pad is the original (OEM), the latter pad is the subsidiary industrial production (SIPM), and the third pad is the Turkish production (TM). These brake pads which have different compositions; components, wear and friction characteristics, mechanical and physical properties were investigated and also the environment and usage were compared among each other. For chemical analysis, energy distribution spectroscopy (EDS) system integrated with scanning electron microscope (SEM) and X-ray fluorescence (XRF) device were used. Thermal gravimetric (TG) analysis was performed to determine the mass losses in the pad materials. Wear friction tests of pads were made according to JIS D 4411 standard. Apart from these, the hardness, density and internal shear strength values of the pads are measured
Dynamic time warping based connectivity classification of event-related potentials
No full textHuman brain electrical responses measured as Electroencephalogram epochs have different characteristics by means of amplitude and frequency content depending on the conditions and stimuli. Event-related potentials are the responses given to the stimuli and can be measured using the EEG. The average of these epochs are computed to remove the background activity and helps to exhibit the response to stimuli solely. In the concept of this study, dynamic time warping based connectivity features are used to classify the single-trial ERP epochs. Color Stroop test was implemented and ERP data are collected from 10 subjects. Support vector machine and K-NN classifiers are used and accurate classification results are achieved with the use of DTW metrics. © 2019 IEEE
The impact of US monetary growth on Bitcoin trading volume in the current economic uncertainty
No full textThis study examines the effect of US monetary growth on Bitcoin trading volume. To achieve this purpose, firstly, the symmetric causality test is used. Following this test, another symmetric causality test is used to reveal a time-varying causal effect between variables. The data set covers the period from July 2010 to July 2019. The results of the first symmetric causality test, which considers the time interval of the study data as a whole, show that there is no causal relationship between variables. According to the results of the second causality test, these support the previous results substantially. However, an interesting detail is the causal relationship between variables for the period between April 2019 and July 2019. The reason for this relationship could be that investors who are indecisive during the current economic uncertainty add Bitcoin to their portfolios in response to the Federal Reserve's decisions. © 2020, IGI Global

faktörlerden biri, finansal stres yaşayan Yunanistan, İspanya ve Portekiz gibi ülkelerin
makroekonomik temellerindeki dengesizliklerdir. Kriz döneminde, makroekonomik
göstergelerdeki sıkıntılar, küresel yatırımcı algısının bozulması ve risk primindeki
artışla birlikte, söz konusu ülke CDS (kredi temerrüt swap) primlerinin belirgin şekilde
yükselmesine yol açmış; uygulanan tasarruf programlarına rağmen, CDS primleri yüksek
seviyelerini bir süre korumuştur. Bu çalışmanın amacı, Türkiye’de, mali dengeye işaret
eden bütçe açığı/GSYİH ve cari açık/GSYİH oranları ile ülke CDS primleri arasındaki
ilişkinin 2006:Ç1-2018:Ç3 dönemi verileri kullanılarak analiz edilmesidir. Türkiye
İstatistik Kurumu Veritabanı’ndan ve Bloomberg’ten elde edilen çeyrek dönem
verileriyle yapılan analizde, Fourier ADF birimkök testi ve Fourier Granger nedensellik
testi kullanılmıştır. Bu testler, çok sayıda yapısal kırılmanın analizde dikkate alınmasına
olanak sağlayarak, sonuçların güvenirliğinin artmasına katkıda bulunmaktadır. Çalışma
sonuçları, Türkiye’de, 2006:Ç1-2018:Ç3 döneminde cari açık/GSYİH oranı ile CDS
primleri arasında bir nedensellik ilişkisi olduğuna işaret etmektedir. Buna göre, söz
konusu dönemde, mali dengeye indikatörlerinden olan cari açık/GSYİH oranı, CDS
primleri üzerinde kısa dönemde etkiye sahip bulunmaktadır
