Piezoelectric composites have become increasingly important in energy harvesting from vibration and, more recently, flow-induced vibration. The compatibility of piezoelectric devices has allowed tuning harvesters to the ...

In the present paper, wave propagation behavior of porous temperature-dependent functionally graded curved beams within the thermal environment is analyzed for the first time. A recently-developed method is utilized which ...

The knowledge of wave scattering and power flow in waveguide structures is important for many engineering applications. In this paper, power flow and scattering in a straight-helical-straight waveguide structure are ...

Heart attack is one of the leading causes of human death worldwide. Every year, about 610,000 people die of heart attack in the United States alone—that is one in every four deaths—but there are well understood early ...

Today, increasing levels of water demand become a particularly serious challenge for many countries, especially since water is an essential element for production of transportation fuels. Unfortunately, no research efforts ...

This paper compares the models of replacement first, replacement interval, replacement last and replacement overtime to decide which policy would be better before or after a specified time T in the viewpoint of cost saving. ...

Active Noise Control (ANC) is used in controlling low frequency noise where passive control is ineffective. Most (ANC) systems use physical cables to connect various parts of the system for operation. This can be bulky and ...
