Receiver functions in central Tibet implications for crustal structure and anisotropy

Seismic images of crustal variations beneath the East Anatolian Plateau (Turkey) from teleseismic receiver functions Özacar, Atilla Arda; Gilbert, Hersh; Beck, Susan L. (2010-12-01) We used teleseismic P-wave receiver functions recorded by the Eastern Turkey Seismic Experiment to determine the crustal structure across an active continent-continent collision zone. Moho depth and V-p/V-s variations in the region are mapped by incorporating crustal multiples and later two-dimsional (2-D) seismic profiles are produced using a common conversion point technique with our crustal V-p/V-s estimates. Moho depths do not correlate with surface topography and reveal a relatively thin crust consiste...
Spatial and temporal distribution of inorganic and organic pollutant concentrations at Northwestern Anatolia Sarısaltık, Ufuk; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2019) Concentrations of inorganic pollutants including NO2, SO2, O3 and organic pollutants including benzene, toluene, ethylbenzene, o-xylene and m&p-xylene, which are known as BTEX compounds were measured on a seasonal basis in 13 cities located in the Central and Northern parts of Anatolian Plateau. Cities included in measurements were Ankara, Bartın, Bolu, Çankırı, Düzce, Eskişehir, Karabük, Kastamonu, Kırıkkale, Kırşehir, Kütahya, Yozgat, and Zonguldak. Sampling was performed in four seasonal campaigns in eac...
Magnetic properties of multiband U=infinity Hubbard model on anisotropic triangular and rectangular lattice strips CHERANOVSKII, VO; Esentürk, Okan; PAMUK, HO (1998-11-01) We study the dependence of the ground state spin of a multiband Hubbard model with infinite electron repulsion on anisotropic triangular and rectangular lattice strips on the model parameters. Considering the results of numerical calculations for the exact spectra of finite triangular lattice strips at different values of hopping integrals, we show the existence of a type of magnetic transitions with the jump of the ground state spin between minimal and maximal values. This transition is found only for spec...
Vibration analysis of cracked beams on elastic foundation using Timoshenko beam theory Batıhan, Ali Çağrı; Kadıoğlu, Fevzi Suat; Department of Mechanical Engineering (2011) In this thesis, transverse vibration of a cracked beam on an elastic foundation and the effect of crack and foundation parameters on transverse vibration natural frequencies are studied. Analytical formulations are derived for a beam with rectangular cross section. The crack is an open type edge crack placed in the medium of the beam and it is uniform along the width of the beam. The cracked beam rests on an elastic foundation. The beam is modeled by two different beam theories, which are Euler-Bernoulli be...
UNIFORM AND NONUNIFORM V-SHAPED ISOTROPIC PLANAR ARRAYS Filik, Tansu; Tuncer, Temel Engin (2008-07-23) In this study, isotropic V-shaped uniform and nonuniform arrays are considered. An isotropic array has the same value for the Cramer-Rao bound (CRB) for all direction of arrival (DOA) angles. The conditions for isotropic V-shaped arrays are presented and closed form expressions for V-shaped uniform and nonuniform arrays are found. These expressions return the V-angle for the array. Therefore, given the number of sensors and sensor displacements, isotropic performance V-angle can be found easily. V-shaped ar...
