Feature extraction in shape recognition using segmentation of the boundary curve
(Elsevier Science BV, 1997-10)We present a new method for feature extraction of two-dimensional shape information based on segmentation of the boundary curve. This approach partitions closed shapes into segments and finds their angular spans. The number ... -
Analysis of self noise in a clock recovery systems with a high-order nonlinearity
(IEEE, 1998)This paper presents a new technique to compute efficiently the I and Q spectra, and the I - Q cross-spectrum of the self noise appearing at the output of the zero-memory, high order nonlinear device employed in a clock ... -
Construction of some classes of two-variable lossless ladder networks with simple lumped elements and uniform transmission lines
(IEEE, 1998)In this paper, explicit two-variable description of some classes of ladder networks of high-pass, bandpass and band-reject types are presented. Up to a certain complexity, for two-element kinds of these type regular ... -
Adaptive identification and equalization of magnetic recording channels
(Wiley-Blackwell, 1998-03)A new RLS adaptive Volterra filter is presented. The nonlinear filtering problem is transformed into an equivalent multichannel, but linear, filtering problem. The multichannel input signal is completely orthogonalized ... -
Adaptive Volterra channel equalisation with lattice orthogonalisation
(Institution of Engineering and Technology, 1998-04)The authors present a new recursive least-squares adaptive nonlinear equaliser based on Volterra series expansion. The main approach is to transform the nonlinear equalisation problem into an equivalent multichannel, but ... -
Kinematic analysis of robotic bevel-gear trains: An application of network model approach
(Springer Netherlands, 1998-04)The network model approach for rigid and multi-rigid body systems developed recently [1,2] can also be used conveniently in formulating system equations or equations of motion of three-dimensional mechanical systems of ... -
A Numerical real frequency broadband matching technique based on parametric representation of scattering parameters

Analysis of self noise in a clock recovery systems with a high-order nonlinearity
(Bogazici University Bebek, 1999)This paper presents a new technique to compute efficiently the I and Q spectra, and the I - Q cross-spectrum of the self noise appearing at the output of the zero-memory, high order nonlinear device employed in a clock ... -
On the kinematic of a 3-DOF Stewart platform
(John Wiley & Sons Inc, 1999-02)The kinematic behavior of the Stewart platform has been discussed in the literature by many researchers. In the present article, a special form of the Stewart platform, namely, the 3-degrees of freedom platform with ... -
Design of optimum nyquist signals based on generalized sampling theory for data communications
(IEEE, Piscataway, NJ, United States, 1999-06)A new method is given for the optimal design of bandlimited Nyquist-type signal shapes for data communications, which maximizes its energy in a given time interval. The method is based on the periodically nonuniform sampling ... -
Analysis of layered media terminated with an impedance surface varying in lateral directions
(Springer-Verlag Berlin, 2000)Determination of the constitutive parameters of a region from data provided by remote sensing is an extremely interesting and important topic from various points of view. In a large class of problems of this type, the ... -
The concept of confluence and the edge conditions for a wedge bounded by material sheets
(IEEE, 2000)The edge conditions which dictate the asymptotic behaviour of the electromagnetic field near the edges play a crucial role in solving boundary-value problems involving boundaries having edges, in analytical studies they ... -
