In our paper, we consider the dynamics of blood pressure, initiated in [M.U. Akhmet, G.A. Bekmukhambetova, A prototype compartmental model of blood pressure distribution, Nonlinear Anal. RWA (in press)], concentrating on the interaction between systemic arterial pressure and periphery blood pressure. A system of impulsive differential equations is applied as a model. The main result of the present paper is the existence of Devaney's chaos ingredients: sensitivity of solutions, transitivity, and existence of infinitely many periodic solutions, in the case, when the moments of discontinuity are defined as a special initial value problem. The method of creating a chaos [M.U. Akhmet, Dynamical synthesis of the quasi-minimal set, Internat. J. Bifur. Chaos (in press); M.U. Akhmet, Devaney's chaos in a relay system, Commun. Nonlinear Sci. Numer. Simul. 14 (2009) 1486-1493; M.U. Akhmet, Li-Yorke chaos in the system with impacts, J. Math. Anal. Appl. 351 (2009) 804-810] is applied. Appropriate examples are provided, including a simulation of the chaotic attractor.

THE INFLUENCE OF MANUFACTURING DEFECTS ON STRUCTURAL PERFORMANCE OF COMPOSITE OVERWRAPPED PRESSURE VESSELS Yurdakul, Kıvanç; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2022-2-04) In this study, the influence of defects that are occurred in manufacturing operations of filament wound composite overwrapped pressure vessels on burst pressure is investigated experimentally. Firstly, material characterization methods such as tensile testing and fiber volume fraction testing of carbon/epoxy composite specimens are completed. Following determining of different layer configurations for small scale composite pressure vessels, manufacturing and burst testing of vessels are accomplished. Ef...
The Spectral and temporal properties of MAXI J1409-619 Dönmez, Çağatay Kerem; Baykal, Altan; Department of Physics (2019) In this thesis, spectral and timing analysis of the transient high-mass X-ray binary (HMXB) pulsar MAXI J1409-619 are presented. MAXI J1409-619 was discovered in October 2010, and went into an outburst in early December 2010 until February 2011. Observations of Swift and RXTE throughout this period are used in the thesis. The analysis results are in line with the assertion that MAXI J1409-619 is an accretion-powered pulsar. Time-resolved energy spectra of RXTE and Swift data confirm the previously reported ...
Investigation of the fluidity of biological fluids with a PDDTBN spin probe Severcan, Feride; Acar, B; Gokalp, S (1997-06-01) The aim of this study is to ascertain whether the electron spin resonance technique using perdeutero-di-t-butyl nitroxide (PDDTBN) as a spin probe is able to monitor relative fluidity changes occurring in body fluids, such as blood and parotid saliva, according to different physiological conditions. The present study reveals that the spin probe PDDTBN is able to monitor the fluidity changes in parotid saliva related to habitual smoking, and in whole blood related to the estradiol level. The rotational corre...
THE ROLE OF RANDOM NOISE ON EFFORTS IN GROUP CONTESTS İNTİŞAH, Merve; Büyükboyacı Hanay, Mürüvvet İlknur; Department of Economics (2022-2) We theoretically and experimentally study the effect of random noise on effort level in individual and three different types of group contests: perfect-substitutes, best-shot, and weakest-link. Subjects compete for either a high prize value or a low prize value in individual contests. The theoretical model shows that individual effort increases with prize value but decreases with noise variance. Our experiment finds that in individual contests, subjects who compete for a low prize decrease their efforts as ...
The effect of different solvents on the performance of zeolite-filled composite pervaporation membranes Sener, Tansel; Okumus, Emin; Gurkan, Turker; Yılmaz, Levent (2010-10-15) The aim of this research is to study effect of different solvents on the membrane morphology and on the performance of zeolite-filled composite pervaporation membranes. PAN (polyacrylonitrile) was used as a base polymer and zeolite 13x (32 wt.%) was used as the filler. The solvents considered were DMF (dimethyl formamide), DMSO (dimethyl sulfoxide), DMAc (dimethyl acedamide) and THF (tetrahydrofuran). The cross-sectional morphology of manufactured membranes shows three layers: a zeolite-free polymer layer, ...
