In recent years, the rail transport has achieved rapid development. In assuming the responsibility of promoting the transport task of the economic development, it also faces greater challenges of the rapid growth of passenger volume and safety guarantee. To carry out research on rail traffic safety assessment has essential theoretical and practical significance in protecting public property and...

The wheel and rail interaction is the main influence on the dynamic response of a rail vehicle. Any changes in the wheel and rail will change the overall response of the vehicle. The condition monitoring challenge is to interpret these changes into useful condition information. This paper presents the results from initial feasibility studies into model-based condition monitoring at the wheel-ra...

The products in the real-world application to be studied in this thesis are the rail cars used by BASF to transport products between plants and from plants to customers. The transported product poses minimum requirements on certain rail car characteristics (material, heating, etc.). These characteristics define a rail car type. Types with higher quality characteristics can be used as substitute...

The empirical evidence shows that travel time is crucial for rail transport to be a competitor to air transport. However, there are no papers testing whether travel time has a direct effect on airline pricing. This paper is a step towards filling this gap. We test and quantify the effect of rail travel time on airline fares, using unique data at flight-level. We find that airlines design pricin...

Adaptive noise cancelling (ANC) is a technique which is very effective to remove additive noises from the contaminated signals. It has been widely used in the fields of telecommunication, radar and sonar signal processing. However it was seldom used for the surveillance and diagnosis of mechanical systems before late of 1990s. As a promising technique it has gradually been exploited for the pur...

Surface cracks are typical defects in high-speed rail (HSR) slab tracks, which can cause structural deterioration and reduce the service reliability of track system. However, question how to effectively detect quantify surface remains unsolved at present. In this paper, a novel crack-detection method based on infrared thermography is adopted rail-track slabs. method, thermogram acquired by an c...

Commuter rail systems are widely regarded as an effective transportation alternative to reduce energy consumption and emissions in large urban areas. Use of commuter rail systems in the United States is on the rise, with annual ridership increasing by 28 percent between 1997 and 2007 [1]. With growing concerns about the sustainability and environmental impacts of transportation, modal energy ef...

In this work, the possibility of application device with a non-standard (side) piezoelectric sensor installation for rail condition monitoring is considered. The aim reducing risks using single-strand flaw detectors on railway tracks fixation system in form two rebords. Also, allows you to obtain new qualification criterion integrity rail, which located railroad groundwork. This presence signal...

This paper describes a symmetric ultra lowvoltage (ULV) rail-to-rail CMOS amplifiers using floating gates. Simulation of a compact differential ULV amplifier is presented.
