Yüksek frekanslı devirsel çökellerde hiyerarşi: platform içi ve pelajik karbonatlardan örnekler

Experimental investigation of silicon carbide formation from high energy ball-milled rice husks via pyrolysis Anık, Alper; Geveci, Ahmet; Department of Metallurgical and Materials Engineering (2012) In this thesis work, it was aimed to optimize the conditions to produce silicon carbide (SiC), from rice husks from Turkish Thrace Region, via pyrolysis. Rice husks, coked at 500oC, were high energy ball-milled prior to pyrolysis, in order to investigate the effects of ball-milling on pyrolysis temperature, pyrolysis time and morphology of the SiC produced. Samples of rice husks subjected to different ball milling conditions, were pyrolyzed at temperatures varying from 1500oC to 1600oC and for times varying...
Finite volume solutions of 1D Euler equations for high spped flows with finite-rare chemistry Erdem, Birşen; Tuncer, İsmail Hakkı; Ak, M. Ali; Department of Aerospace Engineering (2003) In this thesis, chemically reacting flows are studied mainly for detonation problems under 1D, cylindrical and spherical symmetry conditions. The mathematical formulation of chemically reacting, inviscid, unsteady flows with species conservation equations and finite-rate chemistry is described. The Euler equations with finite-rate chemistry are discretized by Finite-Volume method and solved implicitly by using a time-spliting method. Inviscid fluxes are computed using Roe Flux Difference Splitting Model. Th...
Intraday price reversals with high frequency data : applied to BIST 100 index Cingöz, Fatih; Oran, Adil; Department of Financial Mathematics (2021-3-03) Investors are willing to exploit opportunities to earn abnormal profits. Event studymethodology has received considerable attention to catch these opportunities. How-ever, the literature dealing with short-term reactions to large price movements isquite small regarding emerging markets because of difficulties in collecting intra-day dataset. In this thesis, we contribute to the literature by providing evidence aboutthe existence of overreaction and intraday reversal effect over a 13-y...
High performance near/short wavelength infrared megapixel InGaAs focal plane array fabrication development and new design proposals Karaca, Utku; Kocaman, Serdar; Department of Electrical and Electronics Engineering (2018) In0.53Ga0.47As is the most appropriate material system for Short Wavelength Infrared (SWIR) detection at ~1.7 μm cutoff wavelength with its relatively lower cost and high performance. Ultra-low dark current (~ nA/cm2) has been recently demonstrated in InGaAs photodetectors with planar type process by eliminating surface leakage current. Here, a fabrication procedure for planar InGaAs photodetectors with unique pixel isolation methods has been developed and ~10 nA/cm2 dark current density levels were obtaine...
Scanning imaging with energy photons Emre, Eylem; Esendemir, Akif; Department of Physics (2003) An inspection system was required in order to eliminate the difficulties which appear during the inspection of the vehicles according to specific criteria at Turkish Custom Border in a short time and effectively. In this thesis, we performed experiments on such a system to obtain the overall performance of its inspection quality. We firstly give with reasons, why the source of beam is selected as X-ray source. The subsystems of the main system are the accelerator subsystem and detector subsystem. Their stru...
