Developing a portable, high-speed, low-cost desktop photoacoustic tomography imaging system by Kalva, Sandeep Kumar

“…Usually Nd:YAG-OPO laser is bulky, heavy and needs an optical table to deliver non-fluctuating laser beam and it needs external op- tics (reflectors/prisms) to direct the laser beam onto the sample (there are portable OPO lasers from OpoTek, EKSPLA, and various other companies that do not require optical table but they are more expensive than conventional Nd:YAG-OPO lasers). …”

Optimizing MC-ICP-MS with SEM protocols for determination of U and Th isotope ratios and 230Th ages in carbonates by Lin, Ke, Chiang, Hong-Wei, Lu, Yanbin, Wang, Xianfeng, Liu, Xiaokang

“…Non-linear behavior was not observed in the MasCom SEM with a retarding potential quadrupole in our MC-ICP-MS system when the beam intensity was limited to < ∼1 × 10 6 cps. We performed a series of tests to examine the influence of tuning parameters, peak shift, and operating voltage of the SEM on isotopic measurements. …”

Robot programming using augmented reality by Chong, Jonathan Wun Shiung

“…Collision-free paths for userdefined start and goal configurations are then generated using a beam search strategy. The second part of this work is the development of a new RPAR methodology aimed at applications such as arc welding and laser cutting, where the end-effector of the robot is constrained to follow a user-defined 3D path at a certain orientation, consistently with respect to that path. …”
