Analysis of an Inverse Problem Arising in Photolithography [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2010
We consider the inverse problem of determining an optical mask that produces a desired circuit pattern in photolithography. We set the problem as a shape design problem in which the unknown is a two-dimensional domain. The relationship between the target

Bayesian Random Tomography of Particle Systems

open access: yesFrontiers in Molecular Biosciences, 2021
Random tomography is a common problem in imaging science and refers to the task of reconstructing a three-dimensional volume from two-dimensional projection images acquired in unknown random directions. We present a Bayesian approach to random tomography.

Discovery of New Ti-Based Alloys Aimed at Avoiding/Minimizing Formation of α” and ω-Phase Using CALPHAD and Artificial Intelligence

open access: yesMetals, 2020
In this work, we studied a Ti-Nb-Zr-Sn system for exploring novel composition and temperatures that will be helpful in maximizing the stability of β phase while minimizing the formation of α” and ω-phase. The Ti-Nb-Zr-Sn system is free of toxic elements.

A Design Optimization Study for the Die Dimensioning Using the Locking Nut Folding Simulation

open access: yesJournal of Mechanical Engineering, 2021
An inverse analysis based on optimization process is performed to determine die curvatures for a locking nut’s flange folding process which has highly nonlinear material behaviour. The nut material is AISI C1040 steel.

Uncertainties in carbon residence time and NPP-driven carbon uptake in terrestrial ecosystems of the conterminous USA: a Bayesian approach [PDF]

open access: yesTellus: Series B, Chemical and Physical Meteorology, 2012
Carbon (C) residence time is one of the key factors that determine the capacity of ecosystem C storage. However, its uncertainties have not been well quantified, especially at regional scales.

Delayed and rushed motions through time change [PDF]

open access: yes, 2020
We introduce a definition of delayed and rushed processes in terms of lifetimes of base processes and time-changed base processes. Then, we consider time changes given by subordinators and their inverse processes.
