Re-examination of dynamic load tests on piles
The dynamic load test (DLT) and the rapid load test (RLT) on piles both pursue the full activation of pile capacity during the impact event and evaluate the pile capacity by measuring and analyzing the impact excitation and response signals of pile top ...

The differences in kinematic parameters of hammer throw finalists of the 2017 London athletics world cup [PDF]
Hammer throw is motor-wise an extremely complex throwing discipline with the manifestation of several different forces that impede the rotational movement of the device and the thrower in the projected sagittal plane.

Experimental study on dynamic pipe fracture in consideration of hydropower plant model
In the case of sudden valve closure, water hammer creates the most powerful pressure and damage to pipeline systems. The best way to protect the pipeline system is to eliminate water hammer. The main reasons for water hammer occurrence are valve closure,

A new anti-vibration hammer rust detection algorithm based on improved YOLOv7
Anti-vibration hammer corrosion seriously endangers the safe operation of transmission lines. To better improve the detection effect of anti-vibration hammer corrosion on transmission lines under complex background, in this paper we propose an anti ...
