A real-time, low-latency, FPGA implementation of the two dimensional discrete wavelet transform
Benderli, Oğuz; Tekmen, Yusuf Çağatay; Department of Electrical and Electronics Engineering (2003)
This thesis presents an architecture and an FPGA implementation of the two dimensional discrete wavelet transformation (DWT) for applications where row-based raw image data is streamed in at high bandwidths and local buffering of the entire image is not feasible. The architecture is especially suited for multi-spectral imager systems, such as on board an imaging satellite, however can be used in any application where time to next image constraints require real-time processing of multiple images. The latency...
A Hybrid Perturbational and Transformational Electromagnetics Approach for Modeling Rough Surface Scattering Problems
Kuzuoğlu, Mustafa (2015-07-24)
Perturbation and transformation electromagnetics methods are hybridized for solving electromagnetic scattering from objects with weakly perturbed surfaces within the context of finite element method. A mesh is generated for smooth surface and a transformation medium layer is designed over the smooth surface by using the coordinate transformation technique. The major advantage of this approach is that if multiple solutions are needed for a set of perturbed surfaces, such as in stochastic or inverse problems,...
A new approach to multivariate adaptive regression splines by using Tikhonov regularization and continuous optimization
TAYLAN, PAKİZE; Weber, Gerhard Wilhelm; Ozkurt, Fatma Yerlikaya (2010-12-01)
This paper introduces a model-based approach to the important data mining tool Multivariate adaptive regression splines (MARS), which has originally been organized in a more model-free way. Indeed, MARS denotes a modern methodology from statistical learning which is important in both classification and regression, with an increasing number of applications in many areas of science, economy and technology. It is very useful for high-dimensional problems and shows a great promise for fitting nonlinear multivar...
A new BEM approach for the slow 2D MHD flow about interacting solid particles
Antonie, Sellier; Selçuk, Han Aydın; Tezer, Münevver (2015-07-06)
This work looks at the two-dimensional MagnetoHydrodynamic steady slow flow of a conducting newtonian liquid about two solid insulating particles. It presents a powerful boundary approach to efficiently compute at a reasonable cpu time cost the flow about the particles when the imposed ambient uniform magnetic and the liquid velocity on each particle contour are given. The trick rests on two derived integral representations for the fluid velocity and pressure in the entire liquid domain. The task is thereby...
