With the rapid incensement of personal vehicles, urban traffics congestion is now a prominent problem in many major cities in China. Electronic Toll Collection (ETC) is an efficient solution for traffic jaw problem. This paper introduces an embedded system designed for Dedicated Short Range Communications (DSRC) standard based ETC system of China. In this system, a STM8L151G micro controller was used...
At present, the lack of actual operation experience of the intelligent substation secondary system results in indeterminate maintenance strategy, time-consuming and laborious routing inspection, blindness in maintenance work and some other issues. Based on this, a comprehensive evaluation system of the operation quality of the secondary system is realized firstly. Secondly, the utility function is...
The current ship reporting procedures are a little cumbersome, a large number of ship reports increased the burden of the ship's officer, to a certain extent, affecting the safety of navigation. In order to simplify the ship reporting procedures and reduce the workload which brings to the ship officer, under the background of the e-navigation construction advocated by IMO (International Maritime Organization),...
A typical way to improve the quality of requirements is to assign them to suitable stakeholders for reviewing. Due to different characteristics of requirements and diverse background of stakeholders, it is needed to find an optimal solution for requirements assignment. Existing search-based requirements assignment solutions focus on maximizing stakeholders' familiarities to assigned requirements and...
In survival analysis, the primary goal is to monitor several entities and model the occurrence of a particular event of interest. In such applications, it is quite often the case that the event of interest may not always be observed during the study period and this gives rise to the problem of censoring which cannot be easily handled in the standard regression approaches. In addition, obtaining sufficient...
We consider discrete-time (DT) systems S in which a DT input is first transformed to a continuous-time (CT) format by phase-amplitude modulation, then modified by a non-linear CT dynamical transformation F, and finally converted back to DT output using an ideal de-modulation scheme. Assuming that F belongs to a special class of CT Volterra series models with fixed degree and memory depth, we provide...
In the context of globalization and mass customization, product configurations are differentiated according to market requirements. This paper focuses on the primary challenge of developing a semantically rich product configuration representation that is amenable to automatic reasoning. We propose a Configuration Semantics Representation (CSR), a rule-based ontological formalism that is consistent...
To build a simple picture of M2M communication under service-oriented M2M architecture, a key innovation underlines the enablement of M2M device abstraction and semantics support. However, state of the art structures of M2M devices/software lack common M2M Service Layer for interoperability. Devices/software rely heavily on specific API implementation-oriented data services and the data definition...
With the rapid development of power system and the integration of renewable energy sources, the uncertainties of power system become more complex, which introduce a more challenging for the assessment of voltage stability. This paper presents an analytical solution of static voltage stability assessment based on the PQ plane analysis method with elaborately selected voltage stability indices, and...
We compensate the phase screens generated by the Fourier Transform method based on Kolmogorov and Von Karman spectrum models with subharmonic method and Zernike polynomials. Then we present the performance comparison of these two compensation methods. The results show that in Kolmogorov spectrum model, Zernike polynomials have better compensation effect but in Von Karman spectrum model, subharmonic...
Purpose To study the outlier detection methods and supply practical tools for data mining. Methods A novel parametric outlier detection method called maximum minimum (MaxMin) was presented to solve the crucial outlier detection issue, i.e., the estimation of the distribution parameters of the target normal distribution 'contaminated' with the outliers. Through an iterative rejection sampling procedure,...
Performance of power transmission lines has a great impact on reliability of a particular power supply system of a country. Unreliable power transmission lines can even lead to total power failures resulting with great financial losses. The lightning back flashover effects are recognized as one of the major causes of transmission line outages. In the research on lightning resisting level of transmission...
As CMOS devices scaling down according to the Moore' law, the reliability and stability of circuit become the main challenge for the chip designs in low supply voltage. Markov Random field (MRF) based design methodology presents a new approach to establish high noise-immune structure for low-power circuit design from the viewpoint of energy. We use global mapping to synthesize all two-input functions...
With the rapid development of data collection methods and the digital Yellow River Project, the data resources of the Yellow River has been constantly accumulated. The data resources of Yellow River areautonomous, heterogeneous and dynamic. The problems encountered by the Yellow River Water Conservancy Commission is becoming increasingly prominent, such as resource sharing and exchange of the Yellow...
The traditional statistical method of reliability assessment based on failure data is infeasible for equipment reliability assessment in the case of small sample, especially for zero failure data. And in engineering application, the method of performance reliability assessment can be adopted, but it is also faced with the problem of insufficient performance data. The Bootstrap method can enlarge the...
Smart grid as the next generation of the electricity infrastructure has been already widely in study and pilot implementation in China, part of the project has initially formed a small electricity information center, but for valid mining power usage information to monitoring and early-warning for smart grid electricity users, there is no effective platform. Smart grid power monitoring and early-warning...
The retail industry is connecting the upstream Production enterprise and downstream consumer, and Chinese retail industry has already been deepened from own energy conservation environmental protection, gradually to green supply chain management. In view of China domestic Retail business's development present situation, this article starts from the analysis of the environment friendly practice's environmental...
Association rules mining is an important task in data mining and the normal measures support and confidence are useful for finding association rules between the items. However, the process of finding frequent items would prune infrequent items which may include some useful relationships of association patterns. The new measures comsup, comcof and comsup' are proposed to resolve this problem effectively...
