Multiple-Scale Interactions Affecting Tropical Cyclone Track Changes

open access: yesAdvances in Mechanical Engineering, 2011
Tropical Cyclone (TC) track changes associated with Rossby wave energy dispersion are simulated in a shallow water primitive equation model with an initial field where a TC is located south of a subtropical high.

Orographic Influences on Rainfall and Track Deflection Associated with the Passage of a Tropical Cyclone

open access: yesMonthly Weather Review, 2002
Abstract In this study, a nonhydrostatic mesoscale model [Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS)] was adopted to simulate Supertyphoon Bilis (2000) and investigate the dynamics of orographic rain and track deflection accompanying the storm as it passes the Central Mountain Range (CMR) of Taiwan.

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Real-time Vertical Track Deflection Measurement System

open access: yes, 2008
Track quality is a major factor in railroad safety, and one accepted indicator of track quality is the vertical track deflection. Measuring track deflection from a moving railcar is difficult because there is no stable reference for the measurements.

On the Upstream Track Deflection of Tropical Cyclones Past a Mountain Range: Idealized Experiments

open access: yes, 2016
Upstream track deflection of a propagating cyclonic vortex past an isolated mountain range is investigated by using idealized simulations with both boundary layer turbulent mixing and cloud effects.

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

open access: yesAdvanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

Influence of the railway track parameters to the dynamic responses of the track components

open access: yes, 2002
It is well known that defective wheels and/or irregularities of the rails generate impact forces. Generally vertical impact forces are determined using either field measurement or 2D simulation models.

Estimation of vertical bending stress in rails using train-mounted vertical track deflection measurement systems

open access: yes, 2017
This paper presents a new methodology for the estimation of bending stresses over long sections of rails from the vertical track deflections measured using train-mounted instrumentation.

Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry

open access: yesAdvanced Materials, EarlyView.
Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...

Track behaviour: the importance of the sleeper to ballast interface

open access: yes, 2008
The aim of this research is to develop a fuller understanding of the mechanical behaviour of thesleeper/ballast interface, related in particular, to the forces applied by high speed tilting trains onlow radius curves.
