Signal Feature Extraction and Combination to Enhance the Detection and Localization of Railroad Track Irregularities
(2020)Tracks are critical and expensive railroad asset, requiring frequent maintenance. The stress from heavy car axle loads increases the risk of deviations from uniform track geometry. Irregularities in track geometry, such ... -
Signal Filter Cut-off Frequency Determination to Enhance the Accuracy of Rail Track Irregularity Detection and Localization
(2019)A continuous condition monitoring system to detect and localize railroad track irregularities is achievable with inertial sensors onboard revenue service trains. However, the inaccurate geospatial position estimates of GPS ... -
Sourcing Strategy for Asphalt Production Feedstock Considering Multimodal Transport Options
(2016)This paper examines the logistics and distribution channels for importing heavy crude oil, which is a source of bitumen. The study conducts a sensitivity analysis to assess the suitability of existing or new distillery ... -
Strategic Global Logistics Management for Sourcing Road Oil in the U.S.
(2017)The demand for asphalt and road oil heavily leverages local supply because the product is a hot binder of aggregates that form the final mix needed to pave roads. This paper discusses the supply chain characteristics of ... -
A Systematic Literature Review of Drone Utility in Railway Condition Monitoring
(2023)Drones have recently become a new tool in railway inspection and monitoring (RIM) worldwide, but there is still a lack of information about the specific benefits and costs. This study conducts a systematic literature review ... -
