As displaying different transient optical and X-ray behaviors both among themselves and individually, Be/X-ray binaries (BeXRBs) have been one of the most interesting populations of High Mass X-ray Binaries (HMXBs) since their discovery. Although their standard observational properties can be put together in distinct classes, there still have been several Be/X-ray systems showing unique features beyond these classifications. In this thesis, we first present a new and comprehensive catalog of Be/X-ray binaries and potential candidates in the Galaxy. With this new list, we review the most important properties of all sources and check the evidences leading them to be classsifed as BeXRBs. Next, we investigate the long-term optical/IR and X-ray properties of three BeXRBs selected from the catalog, EXO 0331+530, XTE J1946+274 and SAX J2103.5+4545. We showed that each source has their own characteristics despite their common X-ray outburst types. We also searched for the short-term variations, attributed to the non-radial pulsations (NRP), in the photometric data of the Be stars. Our sample includes IGR J01363+6610, IGR J01583+6713, RX J0440.9+4431, SWIFT J2000.6+3210 and GS 2138+56. Alhtough we did not find any periodic variations, the results are still preliminary since it is an ongoing project.

X-ray analysis of high mass x-ray binary pulsars
Şahiner, Şeyda; Baykal, Altan; İnam, Sıtkı Çağdaş; Department of Physics (2015)
In this thesis, X-ray properties of three high mass X-ray binary (HMXB) pulsars are analysed, using the data of X-ray satellites such as RXTE, INTEGRAL and Swift. Selected sources belong to different subgroups of the HMXB family. The first system, 4U 1907+09 is a classical wind-fed supergiant system with persistent X-ray emission; although it shows irregular flares and dips. SWIFT J1729.9-3437 and SWIFT J0513.4-6547 are newly discovered transient systems. Although the counterpart of SWIFT J1729.9-3437 could...
A Sparse Temporal Mesh Model for Brain Decoding
Afrasiyabi, Arman; Onal, Itir; Yarman Vural, Fatoş Tunay (2016-08-23)
One of the major drawbacks of brain decoding from the functional magnetic resonance images (fMRI) is the very high dimension of feature space which consists of thousands of voxels in sequence of brain volumes, recorded during a cognitive stimulus. In this study, we propose a new architecture, called Sparse Temporal Mesh Model (STMM), which reduces the dimension of the feature space by combining the voxel selection methods with the mesh learning method. We, first, select the "most discriminative" voxels usin...
A Two-Level Homogenization Approach for Polymer Nanocomposites with Coated Inclusions
GÜZEL, DİLEK; Gürses, Ercan (2022-01-01)
In polymer nanocomposites, other than the matrix and inclusion, a third phase so-called interphase, is commonly observed. Inter-phase properties affect the overall macroscopic mechanical behavior. It is crucial to model the interphase and obtain the effective composite properties accordingly. Homogenization theory is very useful and powerful; however, many of the homogenization-based techniques have deficiencies. The goal of the study is to combine two very well-known homogenization techniques to model the ...
Search for ZZ resonances in the 2l2v final state in proton-proton collisions at 13 TeV
Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2018-03-01)
A search for heavy resonances decaying to a pair of Z bosons is performed using data collected with the CMS detector at the LHC. Events are selected by requiring two oppositely charged leptons (electrons or muons), consistent with the decay of a Z boson, and large missing transverse momentum, which is interpreted as arising from the decay of a second Z boson to two neutrinos. The analysis uses data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity ...
The first resolved and detected classical nova shell in X-rays in comparison with the ROSAT detections of hard X-ray emission from classical nova in outburst
Balman, Şölen; Ogelman, HB (2000-01-01)
We present the ROSAT High Resolution Imager (HRI) data of the first resolved and detected classical nova shell in the X-ray wavelengths : The shell of Nova Persei (1901). We find that the shell is composed of knots and has an elliptical shape. The surface brightness is about 703.4+/-54.5 counts arcmin(-2). We estimate that the spectrum is of thermal origin with a luminosity of 8.0x10(31) erg s(-1) and an X-ray temperature of similar to 2.0x10(6) K in the 0.1-2.4 keV energy range. The knots are most likely a...
