The Aw-Rascle (AR) model has attracted more and more attention, because it solves the problem of the anisotropic property of traffic flow which is proposed by Daganzo. The AR model possesses an increasing function of the density which be called as the pressure function. The calibration of the pressure function is a primary work in the research of the model application. In this paper, we calibrate...
This article deals with the boundary feedback control of freeway traffic which is modelled by Aw-Rascle traffic flow model. By means of a Riemann invariants approach, we deduce stabilizing control laws of a single freeway segment. The stability condition is extended to a general class of hyperbolic systems which can describe freeway networks. The control laws design based on this conclusion are illustrated...
Purpose Angiogenesis, estimated by microvessel density (MVD), has been shown to predict poor progression-free survival in women with advanced epithelial ovarian cancer. Inhibitor of growth (ING) family proteins inhibit angiogenesis in a number of cancers. We evaluated the role of ING4 in regulation of angiogenesis in patients with epithelial ovarian cancer. Methods Semi-quantitative RT-PCR was used...
Monitoring and fault tolerance are important approaches to give high confidence that long-running online software systems run correctly. But these approaches will certainly cause high overhead cost, i.e. the loss of efficiency. Multi-core platforms can make such cost acceptable because of the advantage of the parallel performance. For allowing ordinary software developers without any knowledge of...
Program understanding plays an important role in the maintenance and reuse of open source code. Rapid evolving and bad documentation makes the understanding and reusing difficult. Design patterns are widely employed in the open source code. In this paper, we propose a design pattern directed clustering approach to help understand the structure of open source code. According to the approach, we have...
