2012 conference paper

Laser micromachining modeling and laser machined surface errors prediction for biomedical applications

Proceedings of the ASME International Manufacturing Science and Engineering Conference, 2012, 59–68.

By: P. Wongwiwat n, R. Narayan* & Y. Lee n

TL;DR: The analytical model was adapted from the linear function for beam propagation in previous research by using the Gaussian function to improve modeling accuracy and showed how the modeling could solve the complex phenomenon of the overlapping in laser micromachining. (via Semantic Scholar)

A comparison of decision-maker perspectives for optimal cholesterol treatment

IBM JOURNAL OF RESEARCH AND DEVELOPMENT, 56(5).

By: J. Mason n & B. Denton n

TL;DR: A Markov decision process (MDP) is used to show how decision-maker perspectives can influence medical treatment decisions related to cardiovascular risk management in patients with type 2 diabetes, and an inverse MDP model is formulated to estimate the implied monetary value of a year of life, from the societal perspective, according to current U.S. treatment guidelines.
