Aerodynamic shape optimization for minimum robust drag and lift reliability constraint

Papadimitriou D.I., Papadimitriou C. (2016)

A methodology for shape optimization of aerodynamic bodies under uncertainties is presented. Flow-related and geometrical uncertainties are considered and quantified by probability distribution functions. The optimal shape ...

A bayesian framework for optimal experimental design in structural dynamics

Argyris C., Papadimitriou C. (2016)

A Bayesian framework for optimal experimental design in structural dynamics is presented. The optimal design is based on an expected utility function that measures the value of the information arising from alternative ...

Column generation for scheduling shipments within a supply chain network with the minimum number of vehicles

Kozanidis, G. (2014)

We consider the problem of scheduling a set of shipments between different nodes of a supply chain network. Each shipment has a fixed departure time, as well as an origin and a destination node, which, combined, determine ...

Examining travelers "optimal strategies" in transit trip choices, applying a classification tree approach on transit quality of service indicators

Tsami, M. T.; Nathanail, E. G. (2014)

According to Spiess and Florian (1989) [1], at each transfer point passengers may shape the "optimal" for them strategy taking into account minimum generalized travel cost. The generalized cost of trip choices is formulated ...

A hybrid approach to frequent itemset hiding

Gkoulalas-Divanis, A.; Verykios, V. S. (2007)

In this paper, we propose a novel, exact border-based approach that provides an optimal solution for the hiding of sensitive frequent itemsets by (i) minimally extending the original database by a synthetically generated ...

Optimal sensor placement for parameter estimation and virtual sensing of strains on an offshore wind turbine considering sensor installation cost

Mehrjoo A., Song M., Moaveni B., Papadimitriou C., Hines E. (2022)

This paper proposes an optimal sensor placement (OSP) framework for parameter estimation, virtual sensing, and condition monitoring using information theory. The framework uses a Bayesian OSP method combined with modal ...

Robust optimised design of 3D printed elastic metastructures: A trade-off between complexity and vibration attenuation

Cantero-Chinchilla S., Fabro A.T., Meng H., Yan W.-J., Papadimitriou C., Chronopoulos D. (2022)

In this work, a strategy for optimal design of mechanical metastructure is proposed taken into account uncertainties arising from additive manufacturing. A locally resonant Π-shaped beam with parallel plate-like insertions ...
