Experimental and numerical investigations on wind characteristics and wind induced vibrations of bridge structures
… researchers and engineers. For such structures, wind load has become one of the most important dominant loads under consideration in the analysis and design of structures. Thus, accurate and reliable evaluations of the wind characteristics are critical, as the evaluations may provide a solid …

Towards A Mobile Damping Robot For Vibration Reduction of Power Lines
… power lines against harsh environments such as wind-induced vibration (WIV). Currently, Inspection robots are used for maintenance efforts while fixed tuned mass dampers (FTMDs) are used to prevent structural damages. However, both solutions are facing many challenges. Inspection robots are …

Dynamic impact induced by tornadoes through simulations based on two-way wind-structure interactions
… This requires in-depth understanding of the wind characteristics of tornadoes and their wind effects on civil structures, based on which design tornadic wind loading can be properly determined. To achieve this, in this study, Computational Fluid Dynamics (CFD) simulations and Computational …

Enabling Validation of a CubeSat Compatible Wind Sensor
… space science instrument that measures neutral wind characteristics in the upper atmosphere. Neutral gas interactions with plasma in the ionosphere/thermosphere are responsible for spacecraft drag, radio frequency disturbances such as scintillation, and other geophysical phenomena. REDD is …

Effects of human development on aeolian sediment transport rates within an adjacent undeveloped backshore enclave
… 2014. Four events were monitored during strong winds to assess wind characteristics and sediment transport across the Dune, Backshore and Foreshore. Wind characteristics were measured using three anemometer towers each with four or five anemometers deployed at the Dune Crest, Dune Toe and Berm …

Aerodynamic stability of bridges
… the Aerodynamic Stability of Suspension Bridges. Wind has wrecked suspension bridges for over a century but the underlying cause, an increasing harmonic amplitude due to wind, has been ignored until recently. For many years bridges have been designed to withstand horizontal wind pressure, but the …

A Biomimetic, Energy-Harvesting, Obstacle-Avoiding, Path-Planning Algorithm for UAVs
… Flow Method (PFM); the other method seeds a wind-field map based on updraft peak analysis and then applies a variant of the Bellman-Ford algorithm to find the minimum-cost path. Both methods are enhanced by taking into account the performance characteristics of the aircraft using advanced …

Air quality at an electric-arc steel manufacturing plant
… reference method for suspended particulates. A wind recording device was installed at the facility to provide a continuous record of wind data for correlation with the particulate concentrations collected. Weather data obtained from the National Weather Service were also used. A relationship …

Development of a feedback controller for the Antenna Positioner on the MeerKAT Radio Telescope
… model defined with parametric uncertainty. Wind disturbance plays a significant role in the pointing performance of the antenna. Therefore, focus is then placed on developing an appropriate wind model to represent the on-site wind characteristics and the relationship to the drive-axis …

Massive stars in the Galactic Center Quintuplet cluster
… > 6.0$) and show mass-loss rates and wind characteristics typical for radiation-driven winds. By comparison with stellar evolutionary models (Meynet \& Maeder 2003a; Langer et al. 1994), the initial masses were estimated and indicate that the Quintuplet WN stars are descendants from …

Probabilistic extreme response analysis of large wind turbines to natural winds
With increases in size and flexibility of modern wind turbines, especially for offshore applications, an improved understanding and assessment of turbine performance under various wind conditions is increasingly important to greatly reduce the risk and increase turbine efficiency and reliability. …
