Eğri yapı elemanları için karma formulasyon kiriş sonlu elemanı
Sarıtaş, Afşin (null; 2009-06-26)
A curved beam element based on a three-field variational formulation with independent displacement, stress, and strain fields is developed. The displacement field is adapted from Timoshenko beam theory for curved geometry. The nonlinear response of the element arises from the integration of stress-strain relations over several control sections along the element length. The finite element approximation for the beam uses shape functions for stress resultants that satisfy equilibrium and discontinuous strains ...
3D object recognition using scale space of curvatures
Akagündüz, Erdem; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2011)
In this thesis, a generic, scale and resolution invariant method to extract 3D features from 3D surfaces, is proposed. Features are extracted with their scale (metric size and resolution) from range images using scale-space of 3D surface curvatures. Different from previous scale-space approaches; connected components within the classified curvature scale-space are extracted as features. Furthermore, scales of features are extracted invariant of the metric size or the sampling of the range images. Geometric ...
Conserved charges of quadratic curvature gravity theories in arbitrary backgrounds
Devecioğlu, Deniz Olgu; Sarıoğlu, Bahtiyar Özgür; Department of Physics (2010)
We generalize the definition of conserved gravitational Killing charges of quadratic curvature gravity theories to arbitrary backgrounds that admit at least one global (time-like) Killing vector. This charge definition is background gauge invariant and reduces correctly to the already known limit given by [1] when the background is a space of constant curvature. As an application we use this definition to compute the charges of various black holes in New Massive Gravity; namely the BTZ black hole, the black...
Quantum mechanics on curved hypersurfaces
Olpak, Mehmet Ali; Tekin, Bayram; Department of Physics (2010)
In this work, Schrödinger and Dirac equations will be examined in geometries that confine the particles to hypersurfaces. For this purpose, two methods will be considered. The first method is the thin layer method which relies on explicit use of geometrical relations and the squeezing of a certain coordinate of space (or spacetime). The second is Dirac’s quantization procedure involving the modification of canonical quantization making use of the geometrical constraints. For the Dirac equation, only the fir...
Soft decoding of convolutional product codes on an FPGA platform
Sanlı, Mustafa; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2005)
In today̕s world, high speed and accurate data transmission and storage is necessary in many fields of technology. The noise in the transmission channels and read-write errors occurring in the data storage devices cause data loss or slower data transmission. To solve these problems, the error rate of the received information must be minimized. Error correcting codes are used for detecting and correcting the errors. Turbo coding is an efficient error correction method which is commonly used in various commun...
