In this paper, human face recognition of still images has been proposed. The proposed system involves five steps: face detection by AdaBoost face detector, region of interest (ROI) extraction, feature extraction using discrete wavelet transform (DWT), dimensionality reduction by employing independent component analysis (ICA) and classification using k-Nearest Neighborhood (k-NN) classifier. Exp...

Diaphragmatic electromyogram (EMGdi) signal plays an important role in the diagnosis and analysis of respiratory diseases. However, EMGdi recordings are often contaminated by electrocardiographic (ECG) interference, which posing serious obstacle to traditional denoising approaches due to overlapped spectra of these signals. In this paper, a novel method based on wavelet transform and independen...

Freshly dissociated myocytes from nonpregnant, pregnant, and postpartum rat uteri have been studied with the tight-seal patch-clamp method. The inward current contains both INa and ICa that are vastly different from those in tissue-cultured material. INa is abolished by Na+-free medium and by 1 microM tetrodotoxin. It first appears at approximately -40 mV, reaches maximum at 0 mV, and reverses ...

The modulation of L-type Ca2+ current (ICa) by changes in stimulation frequency was investigated in single ventricular cardiomyocytes isolated from guinea pig hearts. Electrical recordings were carried out at 21-25 degrees C and at 33-37 degrees C with the whole-cell patch clamp method, under K(+)-free conditions. A comparison is made between the response to frequency changes for ICa in the bas...

the brain – computer interface (bci) provides a communicational channel between human and machine. most of these systems are based on brain activities. brain computer-interfacing is a methodology that provides a way for communication with the outside environment using the brain thoughts. the success of this methodology depends on the selection of methods to process the brain signals in each pha...

BACKGROUND AND PURPOSE Our study evaluated noninvasive tests for the diagnosis of atheromatous internal carotid artery (ICA) pseudo-occlusion. METHODS Twenty patients (17 men, 3 women; mean age +/-SD, 64.3+/-11.6 years) with angiographically proven atheromatous ICA pseudo-occlusion (20 vessels) were prospectively examined with MR angiography (MRA; 2D and 3D time-of-flight techniques), color D...

Combined heat and power (CHP) systems are employed to supply electrical thermal loads of distribution networks (DNs). However, the loss can significantly hinder transfer through pipelines from CHP consumers Therefore, optimal placement sizing reduce losses, including very crucial. To minimize loss, many methods have been proposed for resource allocation. In this paper, a new approach allocation...

This paper focuses on a robust and flexible edge detection technique based on Independent Component Analysis (ICA) on satellite images for recognition and subjective analysis of changes caused due to Japan earthquake 2011 followed by a devastating tsunami. ICA has been applied to satellite image patches to learn the basis functions using the fixed-point FastICA algorithm. As most of the basis f...

In this paper we address the orthogonalization of independent component analysis (ICA) to obtain transform-based image coders. We consider several classes of training images, from which we extract the independent components, followed by orthogonalization, obtaining bases for image coding. Experimental tests show the generalization ability of ICA of natural images, and the adaptation ability to ...
