754 From Star Trek to Star Wars to Terminator, science-fiction movies and TV series teem with morphing robots. If that vision is indeed a sneak preview of things to come, then the future of robotics is lying face down on a table in Mark Yim’s laboratory at the Palo Alto Research Center (PARC) in California. Or rather, was lying face down, because now it’s trying to stand up. First, the 30-centi...

Abstract The numerical and computation aspects of the Knife-edge Equivalent Contact ( KEC ) constraint lookup table LUT methods are compared in this paper. method implementation uses a penetration-based elastic contact model for flange constraint-based formulation at wheel tread. For method, where an infinitely narrow rail contacts equivalent wheel, regularization tread-flange transition is ado...

Abstract Within this paper, a three-dimensional finite element (FE) model of uniformly loaded, single rubber block, is described and run using loading conditions replicative standard slip resistant footwear test. The FE considers hyperelastic viscoelastic material properties, obtained dynamic mechanical analysis. performance the was evaluated through analytical compression analysis experimental...

This article explores Rosanna Raymond’s performative intervention titled “Soli I Tai—Soli Uta” (Tread on the Sea—Tread Land). Today, many cultural institutions try to develop progressive strategies facilitate “intercultural dialogue.” In this endeavor, are explored, some of which developed in collaboration with experts from so-called “source communities.” Such collaborations have longer histori...

The active tectonics of Anatolia is mostly characterized by its westward motion with respect to Eurasia between the Hellenic subduction in west and Arabia-Eurasia continental collision east. Although most deformation suggested be confined along Anatolia?s boundary elements, viz. North East Anatolian shear zones, recent studies indicate a higher magnitude internal strain accumulation, especially...

In the UK, the use of similar vehicle types by a range of privatised operators gives the opportunity to assess the influence of different route conditions and maintenance practices on wheel tread damage, wheelset life and costs. This paper investigates these influences, using data obtained directly from the train operators and maintainers. By disseminating best practice it is expected that whee...

Abstract Tread wear and rolling contact fatigue (RCF) damage propagated on railway wheels are the two extremely important focal points as they can tremendously deteriorate wheel/rail interactions hunting stability destroy wheel surface materials, subsequently, cut down lifetime of wheels. The on-board anti-slip controllers essence aiming to hold back striking slipping powered wheelsets under lo...
