In this paper, a new Iaguerre domain adaptive filter algorithm, which will be refered to as the Laguerre domain adaptive filter II (LDAF It) has been proposed. The performance of the adaptive filtering algorithms simulated for acoustic echo cancellation application. The performances of the algorithm are specified using various quantities. All the results of the work, for different performance q...

In this paper, a new Ultra-Wideband (UWB) Band-Pass Filter (BPF) for UWB applications is presented. The proposed filter is based on ring resonator with inter-digital coupling at both sides. The inter-digital coupling is used to providing strong coupling and to introduce capacitance effect to achieve at pass-band response. To achieve band rejection characteristics L-shaped open stubs are incorpo...

This paper presents a compact bandpass filter with stopband and high attenuation by using multilayer folded broadside-coupled quarter-wavelength stripline resonators in a low-temperature co-fired ceramic (LTCC) substrate. The proposed bandpass filter centered at 1.1 GHz with a fractional bandwith of 4.5 % shows the first spurious frequency at 3.8 times the center frequency. In comparison to the...

Motivated by the classical TV (total variation) restoration model, we propose a new nonlinear filter-the digital TV filter for denoising and enhancing digital images, or more generally, data living on graphs. The digital TV filter is a data dependent lowpass filter, capable of denoising data without blurring jumps or edges. In iterations, it solves a global total variational (or L(1)) optimizat...

introduction: the accuracy of analyzing functional mri (fmri) data is usually decreases in the presence of noise and artifact sources. a common solution in for analyzing fmri data having high noise is to use suitable preprocessing methods with the aim of data denoising. some effects of preprocessing methods on the parametric methods such as general linear model (glm) have previously been evalua...

here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. these structures are made of a square lattice of silicon rods with the refractive index n1=3.464 surrounded by air (with refractive index n2=1). the broadest photonic band gap occurs at the filling ratio of r/a = 0.17. two linear defect w1 waveguides couple to the ring....

In this paper, we address the design of multichannel L-filters based on marginal data ordering using the Mean-Squared-Error as fidelity criterion. Design procedures subject to the constraints of unbiased or location-invariant estimation or without imposing any constraint are discussed. It is shown by simulations that the proposed multichannel L-filters perform better than other multichannel non...

INTRODUCTION Thrombocytopenia is a potential complication of hemodialysis (HD), and its occurrence has been described even with highly biocompatible polysulfone (PSf) membranes. Dialysis units routinely monitor platelet (PLT) count at the beginning of HD sessions. However, considering that the long-term effects on PLT count could easily be missed, the prevalence of HD-related thrombocytopenia c...
