Advanced numerical solution algorithms for modern em wave propagation problems
(2016)The development of high-order, finite-difference time-domain (FDTD) schemes for modeling and investigating radio-wave propagation problems are presented in this work. The electromagnetic waves can be reproduced precisely ... -
The dynamic response of stereocilia by a gradient elasticity model
(2016)In the inner ear, stereocilia are the mechanosensing organelles of hair cells which respond to fluid motion for the hearing function. Stereocilia are lined up in several rows of increasing height like a stair case. At the ... -
A hybrid two-step approach for evaluating the impact of local rail defect on building vibration
(2017)With the development of light rail transit in urban areas, the effect of railway vibrations on buildings and people inside buildings is a growing problem. In particular, urban transit commonly generates large vibration ... -
Prediction of wave transmission coefficient using neural networks and experimental measurements
(2015)In the present paper, an application of composite modeling is presented, for the estimation of wave transmission through flushing culverts. Specifically, experimental measurements are used and an Artificial Neural Network ... -

Railway-induced ground vibrations in the presence of local track irregularities and wheel flats
(2015)Rapid growth in railway infrastructure has led to numerous environmental technical challenges. This includes ground-borne vibration, which is becoming an increasing problem, particularly in urban environments. A common ... -
Robust optimised design of 3D printed elastic metastructures: A trade-off between complexity and vibration attenuation
(2022)In this work, a strategy for optimal design of mechanical metastructure is proposed taken into account uncertainties arising from additive manufacturing. A locally resonant Π-shaped beam with parallel plate-like insertions ... -
Sensitivity kernels for transmission fibre optics
(2022)Fibre-optic sensing based on transmission offer an alternative to scattering-based distributed acoustic sensing (DAS). The ability to interrogate fibres that are thousands of kilometres long opens opportunities for studies ... -
Simulating the reliability of radio links during superior solar conjunctions
(2018)Some results so far achieved in the framework of the HELIOS (Highly rEliable LInks during sOlar conjunctionS) Project, founded by the European Space Agency (ESA), are presented. The purpose of the project is the definition ... -
Theory of phase transmission fibre-optic deformation sensing
(2022)We present a theory and conceptual examples for fibre-optic deformation sensing based on phase changes of transmitted light. As a first result, we establish an exact relation between observable phase changes and the ... -
Ultrasonic monitoring of bone fracture healing
(2008)Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an ...
