Amplitude analysis of Ds+ →π+π0η and first observation of the W-annihilation dominant decays Ds+ →a0 (980)+π0 and Ds+ →a0 (980)0π+
(American Physical Society, 2019)
We present the first amplitude analysis of the decay Ds+→π+π0η. We use an e+e-collision data sample corresponding to an integrated luminosity of 3.19 fb-1 collected with the BESIII detector at a center-of-mass energy of ...
Search for the decay eta ' -> gamma gamma eta
(AMER PHYSICAL SOC, 2019)
Using a data sample of 1.31 x 10(9) J/psi events collected with the BESIII detector, a search for eta' -> gamma gamma eta via J/psi ->gamma eta' is performed for the first time. No significant eta' signal is observed in ...
RIMFRA: Rotation-invariant multi-spectral facial recognition approach by using orthogonal polynomials
(Springer New York LLC, 2019)
This paper proposes a novel rotation-invariant multi-spectral facial recognition approach (RIMFRA) by using orthogonal polynomials. In the first step, a rotation, illumination and noise invariant local descriptor (RinLd) ...
Measurement of branching fractions of psi(3686) -> phi eta ', phi f(1) (1285) and phi eta(1405)
(AMER PHYSICAL SOC, 2019)
Using a sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector, we perform a study of the decay psi(3686) -> phi pi(+)pi(-)eta. The branching fraction of psi(3686) -> phi eta' is determined to be (1.51 ...
The implementation of the high technology methods of cutting on st 50 alloyed steel and the examination of the effects of cutting operation at the surface of material
(2014)
Since competition has risen in the manufacturing methods of present conditions, the chance of competition has lost in the situations which new or high technologies aren't exactly known. The proper selection is important ...
"Ambiguous Plays of Light (Ziya)": The Critics against Ziya Gokalp and Durkheim's Sociology throughout the National Struggle in Turkey and the Journal of Dergah
(ISTANBUL UNIV, 2014)
The intellectual life of the period of National Struggle has been disregarded in the national historiography of Turkey. In parallel, there is an important gap in the biographical studies narrating Ziya Gokalp's intellectual ...
Search for C-parity violation in J/psi -> gamma gamma and gamma phi
(AMER PHYSICAL SOC, 2014)
Using 1.06 x 10(8) psi(3686) events recorded in e(+)e(-) collisions at root s = 3.686 GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/psi -> gamma gamma and gamma phi decays via ...
Success of ensemble algorithms in classification of electrical impadence spectroscopy breast tissue records
(IEEE Computer Society, 2014)
In this study was performed by using records from breast tissue electrical impedance spectroscopy analysis. The aim of the study is to reveal the impact of ensemble algorithms on success of the classification performance ...
Türkiye’deki kadın izleyicilerin televizyon programlarındaki kadını alımlaması : WOMEN'S WOMAN PERCEPTION ON TV PROGRAMMES IN TURKEY
(ISTANBUL UNIV, 2015)
Perception studies reveal how an audience creates meaning, and observes the interaction between the audience and media message. This study aims to reveal and compare how two similar demographic group audiences perceive ...
Türkiye’de Yükseköğretime Geçiş Sistemi : Transition to higher education in Turkey
(2014)
Türkiye gibi, yükseköğretim olanakları sınırlı ve genç nüfus oranı yüksek ülkeler için üniversiteye giriş sınavları, gençlerin geleceğini belirleme ve üniversite öncesi eğitime etkileri bakımından büyük öneme sahiptir. Bu ...
