Thermal Control During Additive Manufacturing
THE CHALLENGE Additive manufacturing (AM) has emerged as a powerful tool within engineering. Many AM and coating processes rely on thermal input to soften or melt the materials involved in processing. However, this melting or softening typically results in a higher thermal gradient between deposited material and the workpiece, commonly resulting in...

Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy
The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...
