This paper proposes a novel active noise control (ANC) approach that uses an IIR filter and neural network techniques to effectively reduce interior noise. We construct a multiple-channel IIR filter module which is a linearly augmented framework with a generic IIR model to generate a primary control signal. A three-layer perceptron neural network is employed for establishing a secondary-path mo...

Digital filters can be broadly classified into two groups: recursive (infinite impulse response (IIR)) and non-recursive (finite impulse response (FIR)). An IIR filter can provide a much better performance than the FIR filter having the same number of coefficients. However, IIR filters might have a multi-modal error surface. Therefore, a reliable design method proposed for IIR filters must be b...

Intestinal ischemia-reperfusion (IIR) injury affects other organs, like the liver. Glutamine may offer liver protection, following IIR injury. Four groups of rats were studied. In Group A, the animals were subjected to 90 minutes of IIR. In Group B Alanyl-Glutamine dipeptide was administered prior to IIR. Group C, was the sham, and in Group D, the animals were given Alanyl-Glutamine dipeptide, ...

The capabilities of Locally Recurrent Neural Networks (LRNNs) in performing on-line Signal Processing (SP) tasks are well known [1,3,5,6,10,11,14,15]. In particular one of the most popular architecture is the Multi Layer Perceptron (MLP) with linear IIR temporal filter synapses (IIR-MLP) [3,5,10,11,14,15]. IIR-MLP is theoretically motivated as a non-linear generalization of linear adaptive IIR ...

The mechanism of G protein-mediated inhibition of an inwardly rectifying K+ current (IIR) in adrenal chromaffin cells was investigated using the whole-cell version of the patch clamp technique. In case of recording with use of ATP-containing patch solution, the IIR was well maintained; otherwise, it ran down within 15 min. This run down was not prevented by replacement with adenylyl-imidodiphos...

Findings of previous studies have revealed that intestinal mucosal mast cells (IMMCs) are involved in small intestinal ischemia‑reperfusion injury (IIRI). However, time-course changes of mast cell counts and mast cell function in this process remain unclear. The present study aimed to observe the number of IMMCs and to investigate the correlation between their activation and small intestine inj...

In this paper an approach to adaptive IIR ltering based on a pseudo-linear regression and a QR matrix decomposition is developed. The algorithm has proved to be stable and has good convergence properties if the unknown system satisses the strictly positive real condition. The derivation of the algorithm is straightforward and the computational complexity is less than the computational complexit...

En aplicaciones de control inteligente, uno los problemas es determinar el número capas y neuronas en cada capa. Esto se vuelve más complejo con ciertos tipos redes neuronales como las basadas wavelets donde traslaciones dilataciones son parámetros adicionales. Este artículo presenta un estudio comparativo para tipo wavelet que muestran mejor desempeño controlar helicóptero Quanser dos grados l...

Cranfield-style evaluations standardised Information Retrieval (IR) evaluation practices, enabling the creation of programmes such as TREC, CLEF, and INEX, and long-term comparability of IR systems. However, the methodology does not translate well into the Interactive IR (IIR) domain, where the inclusion of the user into the search process and the repeated interaction between user and system cr...

In this paper, we propose to use a multi-longitudinal-mode (MLM) laser as the source of an infinite-impulse response (IIR) microwave photonic filter (MPF) to obtain GHz level free spectral range (FSR). The response function of such an IIR-MPF and the degree of coherence of the laser are discussed theoretically. The degree of coherence of the MLM laser shows a periodic structure which is signifi...
