Sound is one of the important factors in creating a good feeling in a mosque and it can play a role as a sensory medium to communicate spiritually with God. Therefore, the acoustic standards have defined the optimal level ...

This article investigates a new piezoelectric harvester for extracting energy from rotational motions. The harvester''s geometry is selected as a curve to increase the energy harvesting density. For its optimal performance ...

The field of energy harvesting from the environment has emerged as a significant area of research in recent years. Acoustic energy represents a natural source of mechanical energy that can be converted into electrical ...

A vortex-bladeless turbine is a device that works with vortex-induced vibration, which is generated by wind energy. It is one of the innovative devices for wind energy harvesting with some remarkable advantages compared ...

In this paper, a hybrid machine learning/optimization system is developed to identify the optimal configuration of holes on a cantilever beam to achieve a desired natural frequency. Based on a design of experiments, 100 ...

This study focuses on the design and experimental evaluation of a road excitation simulator driven by an electro-hydraulic system. The simulator is employed to create road irregularities, which are then applied to the ...
