Historians looking for first-hand accounts of the experience riding New York subway have their work cut out them. Such information is elusive. Recently, we were given a small vignette what was once going on in mind well-known American fiction writer, Flannery O’Connor. In 1943, at age 18, she traveled from her home rural Milledgeville, Georgia, to City. Riding subway, ensured that two female co...

In this paper, carbon emissions of a monorail transit are calculated using the method whole life cycle, which can be divided into four stages: material manufacturing stage, construction operation stage and demolition stage. phase, units PKT (Passenger Kilometers Travelled) VKT (Vehicle Travelled), while in other three stages, unit is 1 km. The results show that from 1km length 6271.204 tons. ad...

The track fasteners may be damaged by fatigue and impact load during long-term subway operation, resulting in the failure of connecting components between rail plate, spacing support becomes larger, an increase its dynamic deformation, affecting vehicle’s running performance, and, severe cases, endangering safety. A vehicle-subway system model was created to study performance vehicles when fail...

Received: November 30, 2016 Revised: February 13, 2017 Accepted: February 13, 2017 Abstract: Background: Many subway/metro tunnels were constructed using close face shield machines in coarse grain soils in last decades. Configurations of the shield cutterhead and cutting tools are critical in terms of cost and project duration. There are currently no recognized methodologies available for the c...

Streets without names, golden silence on the subway, cables installed above-ground, experimental drive of developers and nosy customers prepare the ground for ultimate perfection. This article analyzes and describes culturally embedded usability scenarios, research activities and geographical and political frameworks of developing mobile technologies in Japan. Furthermore, decisive factors cont...

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 ...

Three years ago, a terrible de agration happened during the excavation of a subway gallery near Neaples. In this paper we describe the geometric modeling and the visual simulation of some possible settings of the catastrophic event. The geometric models and the visual simulation are currently being developed in PLaSM. Both animation and rendering are performed by an Open Inventor interface whic...

AbstractThe Daikai Station subway structure in Japan completely collapsed during the Hyogoken-Nanbu earthquake that occurred on January 17, 1995. Based numerical results obtained by two-dime...
