Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design
The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...
متن کاملDesigning an Open Track & Trace System - the Socio-economic Context
The paper presents both the technical and the socio-economic issues that arise from the design of an open, multimodal end-to-end tracking & tracing system. A brief overview of the general technical design choices is followed by a discussion of the associated socio-economic aspects, including the business context, which is heavily influenced by an electronic commerce environment, and user requir...
متن کاملDynamic Characteristics Analysis of Mats of Ballasted Track on Bridge
A complete vehicle-ballasted track-bridge coupling dynamic model is established. A program to analyze dynamic characteristics is also invented, which is the first time to systematically analyze the dynamic characteristics of vehicles, tracks and bridges when using mats under ballast on the rigid foundation of bridge, in China. The results show that:(1) The mats under ballast are able to reduce ...
متن کاملCircular Mean Filtering For Textures Noise Reduction
In this paper, a special preprocessing operations (filter) is proposed to decrease the effects of noise of textures. This filter using average of circular neighbor points (Cmean) to reduce noise effect. Comparing this filter with other average filters such as square mean filter and square median filter indicates that it provides more noise reduction and increases the classification accuracy...
