In this paper, an energy-efficient phonocardiogram (PCG) signal processor is proposed for wearable long-term cardiac monitoring. To achieve high energy efficiency, the proposed PCG processor employs pipelined and memory-less adaptive architecture to implement wavelet-domain statistic based real-time de-noising, heart sound peak detection, false peak filtering, S1/S2 peak identification and cardiac...
This article discussed the time synchronization performance monitoring system in the scope of 1588v2 telecom profile and presented three monitoring system modes: Master-slave monitoring (node-by-node monitoring), Passive-node monitoring on loop topology network (segmental monitoring), and multicast + unicast monitoring (full-path monitoring). The article detailed three monitoring modes' implementation,...
This paper presents a sensor node processor (SNP) with optimized energy efficiency and performance for intelligent sensing through architecture-level optimization and ultra-low voltage operation with timing-error monitoring. Two typical intelligent sensing applications are demonstrated with the proposed processor, consuming 39 and 29pJ/cycle at 0.5V respectively.
Methods based on multivariate statistical projection analysis have been widely applied for batch processes monitoring. However, conventional methods are linear ones that can only model linear combinations of variables and most batch processes are non-linearity. Traditionally, in process modeling, two solutions for non-linearity have been implemented: non-linear models and local linear models. In this...
The paper proposes the architecture of cloud service system of oil and gas exploration and production (CSSOOGEP). The system uses virtualization to pool infrastructure resource, logically unify, manage, and assign host, network or other resources. It takes advantage of service dynamic integration and other technologies to provide services package and registration, query, update, and on-demand integrated...
The paper analyzes the traditional hook and inline hook's imperfection—easily to be detected and be recovered. To improve the inline hook technology, authors put forward a new technology called secret inline hook which has greater confidentiality and can avoid the malware's detection and falsify effectively. The technology has been successfully applied to the automatic analysis system of malware behaviour...
Based on the method of fuzzy mathematical comprehensive evaluation, this paper assesses the quality of atmosphere in Dazhou with selecting SO2, NO2 and PM10 as evaluation factors, consulting the standards relevant to atmosphere environment and building the attaching function and the weight muster. Then compares the results between the methods of fuzzy mathematical comprehensive evaluation and Air...
In this paper, a miniature low-power Electrocardiogram (ECG) signal processing application specific integrated circuit (ASIC) chip is proposed. This chip provides multiple critical functions for ECG analysis using a systematic wavelet transform algorithm and a novel SRAM-based ASIC architecture, while achieves low cost and high performance. Using 0.18 μm CMOS technology and 1 V power supply, this...
In the Color Management System, monitors play an important role. During the digital workflow, people are used to checking files on displays. The realization of soft proofing will not only increase flexibility, but also reduce producing time and materials. This paper describes the theory of display color management and soft proofing. A method is proposed about using CRT display to simulate the printing...
