When many Lithium-ion battery cells are integrated into a large pack, the possible outcomes resulting from individual cell faults are complex and difficult to predict. Consequently, there is great interest in developing design tools to aid in the optimization of pack performance as well as to understand and mitigate the effects of individual cell failures from propagating to other cells or even th ...

Future military communication systems will utilize advanced superconductor digital electronics that will require efficient cooling at low temperatures near 4 K. We propose to improve the efficiency of pulse-tube cryocoolers by addressing the two primary performance limitations. These are operation in adverse orientations and performance of the regenerator at low temperatures. We will develop (1) a ...

The presence of noise in piping systems often serves as an early warning of mechanical problems such as faulty or cavitating pumps and valves, or boiling in cooling lines. Additionally, in many Naval environments, especially submarines, minimizing noise radiated from vibrating pipes is highly desirable. The ability to quantify the sound pressure level in fluid-filled pipes with an external sensor ...
