Deflection of Highly Relativistic Particles in a Gravitational Field

, 2002
A novel approach to the calculation of the deflection of highly relativistic test particles in gravitational fields is described. We make use of the light-like boosts of the gravitational fields of the sources.

Estimation of wind deflection of high-speed railway catenary based on nonlinear finite element method

机车电传动, 2023
The electrified railway catenary generates wind deflection and vibration under wind load. The longitudinal wind deflection affects the current collection quality of the contact wire and the pantograph, and causes contact force fluctuations and pantograph-

A Novel Laser and Video-Based Displacement Transducer to Monitor Bridge Deflections

Sensors, 2018
The measurement of static vertical deflections on bridges continues to be a first-level technological challenge. These data are of great interest, especially for the case of long-term bridge monitoring; in fact, they are perhaps more valuable than any ...

Applications of the Gauss-Bonnet theorem to gravitational lensing

, 2008
In this geometrical approach to gravitational lensing theory, we apply the Gauss-Bonnet theorem to the optical metric of a lens, modelled as a static, spherically symmetric, perfect non-relativistic fluid, in the weak deflection limit.

Buckling Assessment in the Dynamics Mechanisms, Stewart Platform Case Study: In the Context of Loads and Joints, Deflection Positions Gradient

Computation, 2023
This study introduces an approach for modeling an arm of a Stewart platform to analyze the location of sections with a high deflection among the arms. Given the dynamic nature of the Stewart platform, its arms experience static and dynamic loads.
