An aero-structural algorithm to optimize a flying wing in cruise conditions for preliminary design is developed using two-way interaction between the structure and aerodynamics. A particle swarm routine employed solve multi-objective optimization, aiming reduce weight of aerodynamic drag at point. Different shapes are evaluated during optimization process until reaches optimal aspect ratio, tap...

Abstract In the maritime sector, ship grounding incidents continue to be a serious problem that may lead oil spills, capsizing, severe property damage, and even fatalities. Grounding accidents are currently understood utilizing inadequate statistical datasets, probabilistic scenarios, deterministic computational crashworthiness methodologies due lack of practical tools techniques. The implement...

Direct numerical simulations are performed of turbulent planar Couette flow which are seeded with two-way coupled particles at low volume concentration. Based on an understanding of the development of particle stress (horizontal momentum carried vertically on average by the particle phase) in monodisperse systems at various particle Stokes numbers, several bidisperse and continuously polydisper...

We present a coupled two-way clustering approach to gene microarray data analysis. The main idea is to identify subsets of the genes and samples, such that when one of these is used to cluster the other, stable and significant partitions emerge. The search for such subsets is a computationally complex task. We present an algorithm, based on iterative clustering, that performs such a search. Thi...
