Ensuring safe train operation, minimizing service interruptions, and optimizing maintenance procedures are primary railway industry focus areas. To support these goals, a multi-disciplinary team of researchers at the University Illinois Urbana-Champaign proposed wireless, continuous, accurate methodology to monitor track conditions. This project, referred as “Smart Track”, included development ...

dermatophilosis is a bacterial skin infection and wet conditions like, raining and dipping predispose sheep to it. a great economic loss can be caused by this disease because of its effect on the quality of wool. in iran (near saveh), there was an outbreak of the disease in a herd and the clinical manifestation was different from that of typical dermatophilosis. diffuse wide alopecic area accom...

This article discusses the design and implementation of laboratory equipment suitable for teaching and research in the area of embedded and real-time systems, and examines some possible studies and avenues concerning this subject matter. The laboratory is designed and assembled around several commercially available components. Its main software components are the integrated software development...

The operation and maintenance of railroad turnouts for rail vehicle traffic moving at speeds from 200 km/h to 350 significantly differ the processes track without turnouts, curves, crossings. Intensive wear turnout components (switch blade, retaining rods, rails, cross-brace) occurs. movement a on switch causes high-dynamic impact, including vertical, normal, lateral forces. This intensive whee...

Based on cellular automaton and multi-agent model, we propose a novel hybrid model for distributed simulation of train-group in the railway traffic. An improved cellular automaton model is designed for simulating the underlying structure of the railroad and a multi-agent model is used for dynamic scheduling of the train-group. The combination of both models answers for the distributed simulatio...

Railroad transportation of hazardous materials did not receive as much attention as highway transportation in the academic literature, although comparable volumes are shipped via these two transport modes in North America and Europe. In this paper we present an optimization methodology for the railroad tactical planning problem with risk and cost objectives. We determine the routes to be utiliz...

Abstract The type of subgrade a railroad foundation is vital to the overall performance track structure. With train speed and tonnage increase, as well environmental changes, evaluation influence are even more paramount in structure performance. A geomechanics classification for proposed coupling stiffness (resilient modulus) permanent deformation behaviour evaluated by means repeated triaxial ...

FXPAL’s Pantheia system enables users to create virtual models by ‘marking up’ a physical space with pre-printed visual markers. The meanings associated with the markers come from a markup language that enables the system to create models from a relatively sparse set of markers. This paper describes extensions to our markup language and system that support the creation of interactive virtual ob...

The Brazilian freights railroad transportation, in the last five years, is achieving a significant growth. Currently, the railroad transport operators use performance evaluation measures, related to financial and operational aspects, being that in some cases, there isn’t a relation of cause and effect between them. According to the Brazilian research, 85% of the railroad transport companies use...
