Grinding Management of Rail Profile Based on Abnormal Hunting of High-speed Train
机车电传动, 2020 To study the influence of the polished depth of rail profile at the gauge angle on the low-frequency vibration of high-speed train, a group of rail profiles were obtained by interpolating between the standard CN60 profile and the measured rail profile ...

Scheduling Freight Trains in Rail-Rail Transshipment Yards [PDF]
Transportation Science, 2011 Transshipment yards, where gantry cranes enable the efficient transfer of containers between freight trains, are important entities in modern railway systems. They facilitate a general shift from point-to-point transport to hub-and-spoke railway systems, a shift being driven by concerted efforts within the European Union (EU) to transfer goods traffic

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.

Angewandte Chemie, EarlyView.Rationally designed DNA multivalent aptamers direct specific protein binding to drive self‐assembly into protein‐DNA frameworks (PDFs). Structurally defined protein‐aptamer interfaces organize proteins into triangles, linear and ladderlike chains, and periodic two‐dimensional arrays, enabling precise control over orientation, connectivity, and overall ...

Do light rail systems reduce traffic externalities? Empirical evidence from mid-size european cities
Transportation Research Part D: Transport and Environment, 2021 This paper examines the impact of urban light rail systems on congestion, travel time and pollution. Drawing on data from mid-size European cities, I estimate the impact of supply changes for the entire sample and applied a differences-in-differences ...
