Zonguldak Hardcoal Basin is the largest bituminous coal region in Turkey where extensive underground mining activity exists. Because of this activity subsidence effects have been experienced in different locations of the city. In this study, surface deformations caused by the subsidence have been observed by D-InSAR technique using C-Band RADARSAT data. InSAR data process of 16 RADARSAT images ...

Original scientific paper The ongoing Marmaray Project is one of the largest transportation infrastructure projects in the world. The total length of the over ground and underground Marmaray project is 76,7 km. The first part of project is the Bosphorus Crossing (BC1) with a length of 13,6 km. The BC1 project contains the construction of three bored tunnels and immersed tunnel under the Istanbu...

The On-Line Electric Vehicle (OLEV) is an innovative electricity-powered transportation system which remotely picks up electricity from power transmitters buried underground. Selected as one of “the 50 Best Innovations of 2010” by TIME Magazine, the OLEV is considered as a potential solution for the next generation electric-powered public bus system in Seoul. The prototype of the OLEV based bus...

We consider various analytic methods intended for the evaluation of operating parameters process gas motion in main technological objects transportation systems. On basis these methods, we develop mathematical models aimed at determining operation underground storages. In view similarity hydro-, gas-, and hemodynamic processes, extend accumulated results to case modeling blood circulation large...

Having the right information at the right time is crucial to make decisions during emergency response. To fulfill this requirement, emergency management systems must provide emergency managers with knowledge management and visualization tools. The goal is twofold: on one hand, to organize knowledge coming from different sources, mainly the emergency response plans (the formal knowledge) and the...

Noise in an underground coal mine has dominant components generated mainly from 3 sources: (a) continuous mining machines, (b) roof bolters, and (c) cars/vehicles used to transport personnel and/or coal. Each of these 3 noise sources also has a number of well-defined sub-sources with their own noise characteristics. Sound level meters were used to collect noise data in the form of instantaneous...

Abstract. Several sulfur hexafluoride (SF6) tracer gas experiments were conducted in a subway system to measure the possible pathways of toxic gas for subway tunnels and stations empirically. A new mobile integrated measuring and analysis system was used to achieve high sample rates and a long measurement time. Due to the mobility of the sensors, tracer gas experiments were also carried out ins...

The research is aim to create MRT: Metropolitan Rapid Transit Authority of Thailand (Underground Train) and BTS: Bangkok Mass Transit System Public Company Limited (Sky Train) interactive route navigation map. This map shows the whole routes of both MRT and BTS train stations which are located in the interactive manner. The design is not only a proposal for showing the whole information about d...

These last years have pointed out a significant increase of the power that needs to be transported by underground power cables. As a consequence, large cross section conductors, up to 2500mm2 are now customarily used. The CIGRE group B1-03 has completed in 2005 a work that analyses the actual AC resistance of these large cross section conductors as a function of their design. The authors discus...

In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...
