Lih, Shyh-Shiuh; Lee, Hyeong Jae; Bar-Cohen, Yoseph; Badescu, Mircea; Cervantes, William; Simonini, Alan, 2017, "Development and Testing of a Multi-Transducer System for Measuring Height of Condensed Water in Steam Pipes with Steady-State and Turbulent Flow Conditions", https://hdl.handle.net/2014/46254, 2017 SPIE Smart Structures and Materials/NDE Symposium, Portland, Oregon, March 25-29, 2017, JPL Open Repository
One of the critical requirements for ensuring the safety of a steam pipe is to monitor the condensed water level under operation. For this objective, the authors initially developed methods and obtained preliminary test results based on the use of ultrasonic pulse-echo transducer...

Bar-Cohen, Yoseph; Badescu, Mircea; Bao, Xiaoqi; Lee, Hyeong Jae; Sherrit, Stewart; Freeman, David; Campos, Sergio, 2017, "Synchronous Separation, Seaming, Sealing and Sterilization (S4) using Brazing for Sample Containerization and Planetary Protection", https://hdl.handle.net/2014/46257, 2017 SPIE Smart Structures and Materials/NDE Symposium, Portland, Oregon, March 25-29, 2017, JPL Open Repository
The potential return of samples back to Earth from other planetary bodies would be based on planetary protection requirements that vary depending on the type of body [1]. Potential Mars Sample Return would require the protection of our planet from backward contamination. To fulfi...
