Interaction Prediction Optimization in Multidisciplinary Design Optimization Problems [PDF]

The Scientific World Journal, 2014
The distributed strategy of Collaborative Optimization (CO) is suitable for large-scale engineering systems. However, it is hard for CO to converge when there is a high level coupled dimension. Furthermore, the discipline objectives cannot be considered in each discipline optimization problem.

TOWARDS MULTIDISCIPLINARY ADJOINT OPTIMIZATION OF TURBOMACHINERY COMPONENTS [PDF]

Proceedings of the VII European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2016), 2016
The current state-of-the-art adjoint design optimizations for turbomachinery components focus solely on aerodynamic cost functions and constraints, yet disregard structural feasibility during the optimization procedure. This paper presents the first steps taken towards including structural constraints in a multidisiplinary adjoint optimization design ...

Application of response surface methodology to stiffened panel optimization [PDF]

, 2006
In a multilevel optimization frame, the use of surrogate models to approximate optimization constraints allows great time saving. Among available metamodelling techniques we chose to use Neural Networks to perform regression of static mechanical criteria,

Referral Patterns and Diagnostic Timeliness in Pediatric Cancer: A Hospital‐Based Study in Indonesia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Timely diagnosis and treatment are critical for improving survival among children with cancer. In low‐ and middle‐income countries (LMICs), delays are common and may be influenced by fragmented referral pathways and diagnostic limitations.
