Motion estimation using common spatial frequencies in synthetic aperture imaging
(I E E E, 1996)Correlation processing using fully common spatial frequencies of overlapping subapertures is explored for motion estimation between consecutive excitations in multi-element synthetic aperure imaging. Signals derived from ... -
An ergonomic rendering system for industrial design
(Elsevier Science Bv, 1997)Product design is one of the most important stages in production processes depending on commercial aims and current technology. Success in modelling the products guarantees that customers' requests can be supplied by these ... -
Adaptive multi-element synthetic aperture imaging with motion and phase aberration correction
(Ieee-Inst Electrical Electronics Engineers Inc, 1998)Multi-element synthetic aperture techniques employing subaperture processing over successive firing steps can produce good image quality with simple front-end hardware but are susceptible to motion and phase aberration ... -
An alternative algorithm for the refinement of ULV decompositions
(Siam Publications, 2005)The ULV decomposition ( ULVD) is an important member of a class of rank-revealing two-sided orthogonal decompositions used to approximate the singular value decomposition ( SVD). It is useful in applications of the SVD ... -
An efficient algorithm for rank and subspace tracking
(Pergamon-Elsevier Science Ltd, 2006)Traditionally, the singular value decomposition (SVD) has been used in rank and subspace tracking methods. However, the SVD is computationally costly, especially when the problem is recursive in nature and the size of the ... -
Subspace tracking in low-rank real-time systems
(Elsevier Science Inc, 2006)The truncated ULV decomposition (TULVD) provides good approximation to subspaces for the data matrix and can be modified quickly to reflect changes in the data. It also reveals the rank of the matrix. We develop an updating ... -
Application of an adaptive neuro-fuzzy inference system for classification of Behcet disease using the fast Fourier transform method
(Blackwell Publishing, 2007)In this study, ophthalmic arterial Doppler signals were obtained from 200 subjects, 100 of whom suffered from ocular Behcet disease while the rest were healthy subjects. An adaptive neuro-fuzzy inference system (ANFIS) was ... -
Examination of static and 50 Hz electric field effects on tissues by using a hybrid genetic algorithm and neural network
(Wiley, 2008)The effects of electric fields on tissue are the main subject of many investigations. The importance of this subject comes from the electrical properties of the cell membrane and its sensitivity to changes in electrical ... -
Comparison of MLP neural network and neuro-fuzzy system in transcranial doppler signals recorded from the cerebral vessels
(Springer, 2008)Transcranial Doppler signals recorded from cerebral vessels of 110 patients were transferred to a personal computer by using a 16 bit sound card. Spectral analyses of Transcranial Doppler signals were performed for determining ... -
Propagation of modified Bessel-Gaussian beams in turbulence
(Elsevier Sci Ltd, 2008)We investigate the propagation characteristics of modified Bessel-Gaussian beams traveling in a turbulent atmosphere. The source beam formulation comprises a Gaussian exponential and the summation of modified Bessel ... -
Modifiable low-rank approximation to a matrix
(Wiley, 2009)A truncated ULV decomposition (TULVD) of an m x n matrix X of rank k is a decomposition of the form X=ULVT + E, where U and V are left orthogonal matrices, L is a k x k non-singular lower triangular matrix and E is an error ... -
Advanced Adaptation Techniques for Improved Video Perception
(Ieee-Inst Electrical Electronics Engineers Inc, 2012)Three different advanced adaptation techniques for improving the video perception of users are proposed in this paper. The proposed techniques exploit different adaptation decision-taking and adaptation approaches to adapt ... -
Comparison of Principal Component Analysis and Radial Basis Function Network for Diagnosis of Hypertension
(Turgut Ozal Univ, 2012)In this study, from 150 individuals over the age of 30 taken no drugs, sex, age, height, weight, HDL, LDL, Triglyceride, smoking and uric acid were measured. 65 of them are normal but 85 consist of the patients. Data ... -

(2013)Bu çalışmada meslek yüksekokulu bilgisayar programcılığı bölümü öğrencilerinden uzaktan eğitim ve örgün eğitim alan iki farklı grup arasında öğretim metotlarının, öğrenci başarı düzeylerine etkisi incelenmiştir. Araştırmada ... -
Comparison of natural gas fired and induction heating furnaces
(Springer International Publishing, 2014)Generally, in steel processing systems, steels are heated via induction or combustion furnaces. Natural gas fired furnaces have installation costs advantage while the induction furnaces have the advantages of less scale ... -
Comparison of the Proficiency Level of the Course Materials (Animations, Videos, Simulations, E-Books) Used In Distance Education
(Elsevier Science Bv, 2014)Activities in the field of distance education have shown a significant improvement in the world and Turkey in parallel with the technology. Activities in this field started through newspapers and letters and they were ... -
2D quasi-planar or 3D structures? A comparison between CrBn (n=2-10) wheel-like clusters and their corresponding 3D pyramidal clusters, and their hydrogen storage capability
(World Scientific Publ Co Pte Ltd, 2015)In this study, we investigated stable structures for a transition metal atom-boron (CrB) wheel-like clusters and compared them with their corresponding 3D counterparts by means of density functional theory (DFT). In addition, ... -
