This paper considers the wavelet transform generated by iterating orthonormal power-complementary IIR filter pairs with perfect reconstruction properties. For the implementation of complementary IIR filter pair, the realization structure based on two allpass subfilters in parallel connection is used. The decomposition and reconstruction properties of the example wavelet banks composed of the fi...

Digital filters with linear phase responses, that is, constant group delay responses are needed in many applications for signal and image processing. In this paper, a novel method is proposed for designing maximally flat IIR filters with flat group delay responses in the passband. First, a system of linear equations are derived from the flatness conditions of IIR filters given in the passband a...

BACKGROUND The primary aim of the study was to investigate the cytokine/chemokine response in the kidney, lung, and liver following acute kidney injury (AKI). The secondary aim was to test whether α-melanocyte-stimulating hormone (α-MSH) could prevent a reduction in organ function, and attenuate the inflammatory cytokine/chemokine response within the kidney, lung, and liver following AKI in rat...

Ginsenoside Rb1 (RB1), the most clinically effective constituent of ginseng, possesses a variety of biological activities. The objectives of this study were to investigate the protective effects of RB1 and its underlying mechanism on renal injury induced by intestinal ischemia-reperfusion (IIR) in mice. RB1 was administered prior to inducing IIR achieved by occluding the superior mesenteric art...

The mannose 6-phosphatelinsulin-like growth factor I1 receptor (M6PlIGF-IIR) is a protein that facilitates the transport of acid hydrolases into the lysosome. We have shown that chronic ethanol consumption lowers the M6PAGF-IIR content in rat hepatocytes. Here, we determined the steady-state level of mRNA encoding M6PlIGF-IIR, as well as the rate of receptor synthesis, to ascertain whether the ...

This paper is focused on the learning algorithms for dynamic multilayer perceptron neural networks where each neuron synapsis is modelled by an infinite impulse response (IIR) filter (IIR MLP). In particular, the Backpropagation Through Time (BPTT) algorithm and its less demanding approximated on-line versions are considered. In fact it is known that the BPTT algorithm is not causal and therefo...

The adequateness of IIR models for acoustic echo cancellation is a long standing question and the answers found in the literature are connicting. We use results from rational Hankel norm and least-squares approximation and we recall a test which provides a priori performance levels for FIR and IIR models. We apply this test to measured acoustic impulse responses. Upon comparing the performance ...

The linear-phase IIR filters are described in many cases, mainly due to distortion-free transmission of signals. One of the major problems of IIR filter design is stability, which can be obtained with suitable value of group delay τ . This paper concerns calculation of filter order N and group delay τ in case of quasi-equiripple design of IIR filters. We propose a novel procedure for determinin...
