This proposal aims at solving one of the long prevailing problems in the Railways. This simple method of continuous monitoring and assessment of the condition of the rail tracks can prevent major disasters and save precious human lives. Our method is capable of alerting the train in case of any dislocations in the track or change in strength of the soil. Also it can avert the collisions of the ...

Search tasks for professional searchers, such as law enforcement agen-cies, police officers, and patent examiners, are often more complex thanopen domain Web search tasks. When professional searchers look for rele-vant information, it is often the case that they need to go through multipleiterations of searches to interact with a system. The Dynamic DomainTrack supports rese...

The main goal of TREC dynamic domain track is to explore and evaluate systems for interactive information retrieval, which reflects real-world search scenarios. Due to the importance of learning from user interactions, this track has been held for the second year. The name of the track contains two parts. “Dynamic” means that the search system dynamically adapts the provided ranking to the user...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

in this work dynamic recrystallization behavior of aisi 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 c -1200 c and strain rate range of 0.001 s-1 - 1 s-1. the obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. the flow stress and strain corresponding to the critical, pe...

This research effort focuses on the evaluation of existing design standards for cold-formed steel stud walls and the development of retrofit wall systems. Full-scale wall systems are tested under uniform static pressure using a vacuum chamber. The resistance functions obtained are used to model the dynamic behavior of the walls and to predict performance under blast conditions. This paper focus...

In this paper, we develop a dynamic framework for the modeling and analysis of supply chain networks with corporate social responsibility through integrated environmental decision-making. Through a multilevel supply chain network, we model the multicriteria decision-making behavior of the various decision-makers (manufacturers, retailers, and consumers), which includes the maximization of profi...

Autonomous racing has increasingly become a research subject as it provides insights into dynamic, high-speed situations. One crucial aspect of handling these situations, especially in the presence dynamic obstacles, is generation collision-free trajectory that represents safe behavior and also competitive case racing. We propose local planning approach generates such trajectories for car on an...

An analysis of a nonlinear control system that was used to track the natural frequency of a MEMS resonator is presented in this paper. A phase-locked loop system is used to track the natural frequency of the resonator due to fatigue of the spring element. A model for the control system is established and the system behavior is analyzed using an averaging method. The analysis provides a quantita...

Active steering system of railway vehicles has proven its ability to bridge the gap between stability and curve friendliness. Generally scaled railway vehicles were developed to reproduce the fundamental dynamic behavior of the full size railway vehicle in laboratory conditions. This paper describes the design of the braking/traction control systems as a part of a 1/5 scaled railway vehicle for...
