@inproceedings{fang_bolotnov_2016, title={Bubble tracking simulations of turbulent two-phase flows}, DOI={10.1115/fedsm2016-1005}, abstractNote={Bubbly flow is quite common in various natural and engineering phenomena. In particular, nuclear engineers are interested in fundamental understanding of the bubbly flow behavior due to its importance in cooling light water reactor cores. Given the extreme conditions and complex support structures in nuclear reactor cores, it is very challenging to study the flow behavior using high-fidelity experiments. Typically validated computational codes are chosen as practical tools for the thermal-hydraulic and safety analyses. As the new generations of nuclear reactors are being developed, more advanced modeling techniques are required to design safe and efficient systems.}, booktitle={Proceedings of the asme fluids engineering division summer meeting, 2016, vol 1b}, author={Fang, J. and Bolotnov, I.

However, marketing literature has demonstrated that consumers use various heuristics called noncompensatory choices to simplify their choice decisions. This study aims to explore the suitability of compensatory modeling of these noncompensatory choices for the product design search. This is motivated by the limitations of the existing Bayesian-based noncompensatory mode, such as the screening rule assumptions, probabilistic representation of noncompensatory choices, and discontinuous choice probability functions in the Bayesian-based noncompensatory model. Results from using compensatory models show that noncompensatory choices can lead to distinct segments with extreme part-worths. In addition, the product design search problem suggests that the compensatory model would be preferred due to small design errors and inexpensive computational burden.}, booktitle={International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, 2015, vol 2A}, author={Shin, J. and Ferguson, S.}, year={2016} } @article{shin_lee_2015, title={Reliability analysis and reliability-based design optimization of roadway horizontal curves using a first-order reliability method}, volume={47}, number={5}, journal={Engineering Optimization}, author={Shin, J. and Lee, I.}, year={2015}, pages={622–641} } @article{shin_lee_2014, title={Reliability-based vehicle safety assessment and design optimization of roadway radius and speed limit in windy environments}, volume={136}, number={8}, journal={Journal of Mechanical Design (New York, N.Y. : 1990)}, author={Shin, J. and Lee, I.}, year={2014} }
