The flexible operation modes of microgrid result in an extreme challenge for the protection and control of microgrid. Therefore, this paper proposed a centralized protection and control scheme for microgrid. To identify the faulted region conveniently, the microgrid is divided into several zones in advance. Intelligent circuit breakers communicate with each other, then send real-time information by...
Recent years have witnessed two major trends in the development of complex real-time embedded systems. First, to reduce cost and enhance flexibility, multiple systems are sharing common computing platforms via virtualization technology, instead of being deployed separately on physically isolated hosts. Second, multicore processors are increasingly being used in real-time systems. The integration of...
The hydraulic system and its components can accumulate a significant amount of contaminant after running for a period of time. The accumulated contaminant in the component will degrade its performance and even cause catastrophic failure. Traditional models are distinctly deficient when applied to analyze the performance degradation. In this paper, an improved method is proposed to trace the performance...
In a prior work, we have developed both rate and perceptual quality models for temporal and amplitude (i.e., SNR) scalable video produced by the H.264/SVC encoder. In this paper, we validate from experimental data that the functional form of the rate model is applicable to H.264/AVC encoded video, which has the same temporal scalability but no SNR scalability, but the model parameter values differ...
Visible and near infrared (NIR) spectroscopy was utilized to determine the growing areas of Tremella fuciformis. Principal component analysis (PCA) obtained the cluster plot which shows the difficulty to determine the growing area by the first three principal components. Least-square support vector machine (LS-SVM) was used to establish the calibration model. Successive projections algorithm (SPA)...
As a special kind of security protocol, ecommerce protocols have been analyzed with many formal methods in recent years. However, there is no general specification and verification model checking method to be applied effectively to the four special properties in ecommerce protocols--non-repudiation, accountability, fairness, and timeliness. Based on our previous work on the suitability of colored...
Nowadays, DoS-resistant property has become more and more valuable for designing a cryptographic protocol. In this paper, we concentrate on the suitability of applying CPN Tools to merging Devel-Yao model into Meadows' cost-based framework in the formal analysis of security protocol. Based on Meadows' framework, we propose a formal model for JFK protocol with Colored Petri Nets. Moreover, we add the...
