Mechanical track deterioration due to lateral geometry irregularities [PDF]
, 2012 This thesis deals with how a degraded track geometry influences further degradation of the geometry and the formation of rolling contact fatigue (RCF) and wear of rails. The overall objective is optimisation of railway maintenance.

From Entropic Dynamics to Quantum Theory
, 2010 Non-relativistic quantum theory is derived from information codified into an appropriate statistical model. The basic assumption is that there is an irreducible uncertainty in the location of particles: positions constitute a configuration space and the ...

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials
Advanced Engineering Materials, EarlyView.This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Information modelling of track geometry
Journal of Physics: Conference Series, 2020 Abstract The objective of this study is to substantiate a new method for modelling the railway track geometry. The method includes a new way of path measuring and the resulting method for modelling of track geometry. There can be two variants of track measuring with the new method. The first variant includes measuring only the lengths of

A knowledge-based prognostics framework for railway track geometry degradation
Reliability Engineering & System Safety, 2019 This paper proposes a paradigm shift to the problem of infrastructure asset management modelling by focusing towards forecasting the future condition of the assets instead of using empirical modelling approaches based on historical data.
