PRIME: Powder Removal in Microgravity Environments Experiment

- In Additive Manufacturing (AM) with metal powders, layers of material are deposited and fused to form aerospace 3D printed parts - Remnant powder must be removed from interior cavities and channels to fully clean the part - AM cleaning methods have been a topic of interest

APEX: A Prime EXperiment at Jefferson Lab

APEX is an experiment at Thomas Jefferson National Accelerator Facility (JLab) in Virginia, USA, that searches for a new gauge boson (A' ) with sub-GeV mass and coupling to ordinary matter of g'~ (10{sup -6} - 10{sup -2} )e. Electrons impinge upon a fixed target of high-Z material. An A' is produced via a process analogous to photon bremsstrahlung, decaying to an e +e pair. A test run was held in July of 2010, covering m{sub A'} = 175 to 250 MeV and couplings g'/e > 10{sup -3} . A full run is approved and will cover m{sub A'} 65 to 525 MeV and g'/e > 2.3 x 10{sup -4} .

Laterally Primed Adaptive Resonance Theory

LAPART is an artificial neural network algorithm written in the Python programming language. The algorithm can learn patterns using multi-dimensional hyper boxes. It can also perfrom regression and classification calculations based on learned associations.
