The Loss Characteristics of Curved Fiber at Small Radius
2019 18th International Conference on Optical Communications and Networks (ICOCN), 2019Curved optical fiber sticking onto a round structure has many applications, such as mandrel acoustic sensors and fiber-length scratchable phase modulators. However, the components’ performances are limited by the transmission loss of the wound fibers.

Monitoring of Tram Traffic Noise in the Small Curve Radius
Applied Mechanics and Materials, 2014An excessive noise exposure not only decreases work quality and productivity, it also negatively affects human health. The most accurate data on noise levels can be obtained by measurements; however this approach is really time-consuming and its application is sometimes rather complicated. More frequently, calculation methods are used.

Seismic response analysis on small-radius curve ramp-bridge
2011 International Conference on Multimedia Technology, 2011The urban overpass has developed rapidly with the acceleration of city construction. Ramp-bridge is different from other bridges about construction and stress. In this paper comparative analysis the result by establish finite element model aim at feature of ramp-bridge—cross slope, longitudinal, slope, curvature and stiffness of pier.

Lateral interactions of trains and tracks on small-radius curves: simulation and experiment
Vehicle System Dynamics, 2006The lateral dynamic interaction between trains and tracks on small-radius curves is investigated with theoretical method and field experiment in this article. A vehicle–track spatially coupled model and a simulation software are developed to analyze the dynamic performance of vehicles on elastic tracks. A field experiment is carried out to validate the
