Design and Realization of an Online Power Quality Monitoring System Based on DSP and GPRS

Advanced materials research (2013)

Dong Li Zhou Yong

In order to evaluate power quality more accurately and synthesize the characteristics of the distribution, which has nodes in large quantity and area, an online power quality monitoring system (PQMS) is developed by using the digital signal processor (DSP) and the general packet radio service (GPRS). This PQMS consists of two parts: the power quality monitor (PQM) which is designed on the structure of DSP and the monitoring software (MS) in upper computer which is designed on the platform of LabVIEW. GPRS network provides the communication channel for these two parts. Therefore, supervisors can monitor and analyze the power quality from a long distance. In this paper, the design and realization of each part are described in detail. Experimental results show that the proposed system is fast in response with high accuracy and has the ability of real-time processing.

Dental caries location with line-structured light and integrated calibration method

Li Chen Zhou Zhehai Guoqing Hu Yinglong Li Ying Qin

During the caries treatment, three-dimensional measurement of tooth profile and caries location is one of key steps in the therapeutic process of caries. We propose a three-dimensional vision measurement of tooth crown and dental caries with line structured light. First, an integrated calibration using right angled spot target is executed and the parameters are obtained rapidly. Subsequently, the profile of the tooth crown is reconstructed and the dental caries area is identified. The results show that the reprojection error could reach tens of micrometers and the caries' area is measured as ~ 2.83 mm2. These results indicate high potential in the diagnosis and treatment of dental caries.

A Method of Joint Programming Based on C++ Builder and Matlab

Computer and Modernization (2006)

Dong Li

When making software,a method of joint programming based on C++ Builder and Matlab is discussed.Using this method,the functions of Matlab can be directly called in C++ Builder environment.So it not only avoids plenty of codes but also can run the software without Matlab platform.This paper mainly introduces how to utilize Matcom to call Matlab functions on C++ Builder platform.The method is proved to be highly effective by an example.

An Evaluation Model for Web Service

Tao Han Heqing Guo Dong Li Ying Gao

The evaluation for Web service is essential to select Web services from many candidates, but current evaluation models evaluate Web service only by common service attributes, which can not meet the requirements of end users. We propose an evaluation model for Web service, which customizes reasonable attributes in different domains as evaluation factors, and computes the weights of evaluation factors using machine learning algorithm. The model is implemented in Web service quality evaluation system (WS-QES), which can provide more accurate, reasonable results to end users

UMap: Enabling Application-driven Optimizations for Page Management

arXiv (Cornell University) (2019)

Ivy Bo Peng Marty McFadden Eric Green Keita Iwabuchi Kai Wu

Leadership supercomputers feature a diversity of storage, from node-local persistent memory and NVMe SSDs to network-interconnected flash memory and HDD. Memory mapping files on different tiers of storage provides a uniform interface in applications. However, system-wide services like mmap are optimized for generality and lack flexibility for enabling application-specific optimizations. In this work, we present Umap to enable user-space page management that can be easily adapted to access patterns in applications and storage characteristics. Umap uses the userfaultfd mechanism to handle page faults in multi-threaded applications efficiently. By providing a data object abstraction layer, Umap is extensible to support various backing stores. The design of Umap supports dynamic load balancing and I/O decoupling for scalable performance. Umap also uses application hints to improve the selection of caching, prefetching, and eviction policies. We evaluate Umap in five benchmarks and real applications on two systems. Our results show that leveraging application knowledge for page management could substantially improve performance. On average, Umap achieved 1.25 to 2.5 times improvement using the adapted configurations compared to the system service.

Effective Boundary Detection Method for Complex Target Based on the Snake Model

Journal of Beijing Institute of Technology (2004)

Dong Li

When image objects have non-convex forms or when there exists lower signal-noise rate in the image, the traditional Snake model often cannot detect the object edge effectively. The article attempts to study the characters of image that have complex shape target or noise, so as to improve the traditional Snake in the energy function and operation strategy. It gives new control energy function and discusses the right values of these functions, meanwhile dynamically arranges the Snake points for different target forms. Simulation proves that the new Snake model decreases greatly the Snake's dependence on initial conditions and overcomes effectively the influence of noise. This method enhances the snake's ability of detecting the object edge.

Enabling Differentially Private in Big Data Machine Learning

2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP) (2019)

Dong Li Xiaojiang Zuo Rui Han

Using the machine learning technology to explore the potential value of Big Data brings us into a smarter world, and the way data is mined through data sharing patterns also threatens the privacy of personal data. Differential privacy is a prevalent mechanism to effectively protect the personal data privacy due to the strict and the provable privacy definition, although there are several achievements have reached by combining the differential privacy and traditional machine learning algorithms in a stand-alone mode, little to talk about the distributed environment. To fill this gap, this paper proposes a method to embed the differential privacy mechanism into distributed platform, respectively implements the DPLloyd, GUPT k-means and GUPT logistic regression on the platform of Spark. The evaluation demonstrates that the approach barely interferes the effect of distributed machine learning algorithms and thus achieves the goal of differential privacy.
