Sustainability of Vibration Mitigation Methods Using Meta-Materials/Structures along Railway Corridors Exposed to Adverse Weather Conditions

Vibration mitigation of railway bridges using adaptive damping control

In this paper, the advantage of an adaptive damping system is presented. A damper with variable stiffness is tuned based on estimates of the real-time frequency response, facilitating optimal vibration mitigation. The performance of the developed routines is investigated on an existing tied arch railway bridge. Based on previous field measurements, resonant behaviour of several hangers was foun...

A conventional approach to nighttime visibility in adverse weather conditions

Uncertainty Comparison of Visual Sensing in Adverse Weather Conditions†

This paper focuses on flood-region detection using monitoring images. However, adverse weather affects the outcome of image segmentation methods. In this paper, we present an experimental comparison of an outdoor visual sensing system using region-growing methods with two different growing rules-namely, GrowCut and RegGro. For each growing rule, several tests on adverse weather and lens-stained...

AUV Hydrodynamics In Shallow Water During Adverse Weather Conditions

My long-term goal is to contribute, by means of an accurate hydrodynamics model, to efficient design, development and operation of autonomous underwater vehicles in energetic shallow waters. From a scientific viewpoint, the development of the AUV hydrodynamic model will contribute to a better understanding of wave-body-current interactions, nonlinear shallow-water waves, wave effects on stabili...

Clutter Characterization and Propagation Measurements During Adverse Weather Conditions

The evaluation of sensor performance under adverse weather conditions is critical for the determination of usability during all weather conditions. The Precisions Armaments Laboratory (PAL) located at the US Army Picatinny Arsenal, New Jersey, USA development will enable automated measurement of propagation effects and clutter characterization under adverse conditions.
