accurate and correct performance of controller in cruise control systems is important. hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. as a matter of fact, in this article three approaches have been conducted to-ward this purpose: mit, direct estimation and indirect estimation. these approaches are used as controllers to track refe...

With the development of underground transportation, in order to reduce impact on surrounding environment and traffic, Hejiaying subway island station adopts concealed excavation method. During construction process, considering method, tunnel layout, ventilation requirements, working face as a multi-conductor cave, more stringent requirements are put forward for tunnel. Through combination theor...

Taking as examples of South Gate tunnel project and Metro Line 2 crossing project in Xi’an, this paper analyses the dynamic response of motor vehicle and train loads acting on a tunnel structure .based on finite element model of three-dimensional dynamics. By comprehensive use of load numerical fixation method and analytic formula method, the vibrating load curves of motor vehicle and subway tr...

Outdoor and indoor (subway) samples were collected by passive sampling in urban Seoul (Korea) and analyzed with computer-controlled scanning electron microscopy coupled with energy dispersive x-ray spectroscopy (CCSEM-EDX). Soil/road dust particles accounted for 42%-60% (by weight) of fine particulate matter larger than 1 µm (PM(2.5-1.0)) in outdoor samples and 18% of PM2.5-1.0 in subway sample...

We previously proposed a Colored Petri Net (CPN) based modeling methodology to model multiagent systems. The methodology creates a component to describe the local behavior for each agent, and then concatenate all components to form a system model. In this paper, we focus on a case study to evaluate our modeling approach. The experiments in the case study are based on modeling and simulation of ...
