In computer vision and multimedia search, it is common to use multiple descriptions from different views to represents an object. As one of the popular multi-view learning methods, Multi-view Linear Discriminant Analysis (MLDA) was proposed to maximize discrimination in each view and correlation between two views simultaneously through combining CCA and LDA. However, MLDA does not utilize the local...
As a new computing paradigm, Cloud computing has been advocated by IT industry and academia. It can provide lots of services, however, how to manage these services and guarantee the quality of service, has become one of the key factors for the development of Cloud computing. This paper proposes a hierarchical architecture model of Cloud services resources management and monitoring by integrating the...
Cardiogram recordings include numerous noncardiac containments, which overlap with the cardiac components in the frequency domain. Despite the rich literature in ECG denoising field, there are still noise left in the ECG. Useful information can not be extracted from such ECG. Therefore, the detection ECG validity algorithm was proposed based on wavelet transform. First, signals were preprocessed by...
The bloom of Internet and the convenience of e-Commerce bring a lot of demands of Internet booking applications. There are two challenges in Internet Booking Applications: high volume concurrent processing and complex business processing. Facing these two challenges, we designed an extensible framework for Internet booking applications, which includes an Internet Booking Engine, a rule engine, and...
T-wave alternans (TWA) is a variation in the amplitude or morphology of the T wave of the beat-to-beat ECG which provides a noninvasive and clinically useful marker for the risk of sudden cardiac death (SCD) caused by life threatening arrhythmias. Detection of beat-to-beat microvolt fluctuation of the T wave has been made possible with the use of advanced signal processing techniques and high-resolution...
With the increasing of sudden cardiac death, the developing of a reliable and portable electrocardiograph (ECG) monitor is imminent, especially automated external defibrillators (AEDs). A pivotal component in AEDs is the detection of ventricular fibrillation (VF) by means of appropriate detection algorithms. Various algorithms were proposed, here we proposed a new algorithm, which is based on support...
Respiratory patterns carry clinically useful information. In many cases, ECG signals but not respirations are routinely monitored. We describe a signal processing technique which derives respiratory waveforms from ordinary single-lead ECG. First, we transform the original single-lead ECG signal using quadric B-spline wavelet, then extend R waves of supra ventricular beats in the 2nd approximation...
