In this paper, we focus on the exception handling mechanism of CA-CCML (Context-aware Cooperative Composition Modeling Language). First, according to level of exception generation, we divide Web service exceptions into three broad categories by levels of exception generation, which are Service invocation level exception, Syntax level exception and Semantic level exception. Then we make detail classification...
The thermal power system become more complex as it develops to the direction of large-scale. This brings high efficiency as well as brings much hidden risk. Once the failure appears, less leads to the decrease of operating load, more leads to catastrophic shutdown, and even damage the unit equipment. Therefore, the research on the real-time temperature on-line monitoring system for thermal power units...
Partially occluded faces are common in automatic face recognition in the real world. Existing methods, such as sparse error correction with Markov random fields, correntropy-based sparse representation and robust sparse coding, are all based on error correction, which relies on the perfect reconstruction of the occluded facial image and limits their recognition rates especially when the occluded regions...
In this paper, an effective approach for QRS detection is presented for wearable ECG devices in wireless Body Sensor Networks (wBSN). Significant reduction of high and low frequency noises are obtained under the action of continuous wavelet transform to original ECG signal after the careful selection of scale level. The following Hilbert transform to the transformed signal enables easier location...
A non-uniformly spaced digital FIR filter bank has been proposed for QRS detection in wearable biomedical devices in Body Area Network (BAN) applications. The proposed filter bank is constructed based on frequency-response masking technique and employs two half-band filters as prototype filters, which leads to significant savings in terms of arithmetic operations. The introduction of non-uniformly...
Aiming at the defects & deficiencies existed commonly in the database of dam safety monitoring system used currently such as large data redundancy, bad data consistent, having many difficulties in managing various monitoring data & supporting effectively dam safety monitoring system's successfully running and unsuitable for update & transform, various information, included in the database...
A novel wearable electrocardiograph (ECG) QRS detection algorithm for wearable ECG devices in body area networks is presented in this paper, which utilizes the multistage multiscale mathematical morphology filtering to suppress the impulsive noise and uses the multiframe differential modulus accumulation to remove the baseline drift and enhance the signal. The proposed algorithm, verified with data...
