Evaluation of Modeling Approaches for MILD Combustion Systems With Internal Recirculation
Frontiers in Mechanical Engineering, 2020 Numerical simulations employing two different modeling approaches are performed and validated against experimental results from a moderate or intense low-oxygen dilution (MILD) system with internal recirculation. The flamelet-generated manifold (FGM) and

Frameworks and Results in Distributionally Robust Optimization
Open Journal of Mathematical Optimization, 2022 The concepts of risk aversion, chance-constrained optimization, and robust optimization have developed significantly over the last decade. The statistical learning community has also witnessed a rapid theoretical and applied growth by relying on these ...

Robust Combinatorial Optimization with Locally Budgeted Uncertainty
Open Journal of Mathematical Optimization, 2021 Budgeted uncertainty sets have been established as a major influence on uncertainty modeling for robust optimization problems. A drawback of such sets is that the budget constraint only restricts the global amount of cost increase that can be distributed

Multi-objective topology design optimization combined with robust optimization
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2023 Topology optimization (TO), which is a design optimization technique that does not require design parameters, has been attracting attention. TO has a high degree of freedom and can obtain a novel design shape suitable for desired purposes.
