A simple practical framework for predictive maintenance (PdM)-based scheduling of multi-state systems (MSS) is developed. The maintenance schedules are derived from a system-perspective using the failure times of the overall system as estimated from its performance degradation trends. The system analyzed in this work is a flow transmission water pipe… (More)
Electrical energy is vital to our daily activities. However, energy cost is increasing while much energy is being wasted into the environment. If we can capture these wasted energies, efficiency of energy utilization will be enhanced, and this is the idea of energy harvesting.
In this work, the transient electrical-thermal response of a simple ESD protection circuit to excessive current during an electrostatic discharge (ESD) event is investigated numerically, using 3-D finite element analysis (FEA). The 3-D transient temperature distribution in the circuit can be revealed and the fusing phenomenon of interconnection is captured… (More)
Single-walled carbon nanotubes (SWCNTs) exhibit strong antibacterial activities. Direct contact between bacterial cells and SWCNTs may likely induce cell damages. Therefore, the understanding of SWCNT-bacteria interactions is essential in order to develop novel SWCNT-based materials for their potential environmental, imaging, therapeutic, and military… (More)
3D integrated circuit technology is an emerging technology for the near future, and has received tremendous attention in the semiconductor community. With the 3D integrated circuit, the temperature and thermo-mechanical stress in the various parts of the IC are highly dependent on the surrounding materials and their materials properties, including their… (More)
