ISOGEOMETRIC STRUCTURAL SHAPE OPTIMIZATION USING PARTICLE SWARM ALGORITHM

One primary problem in shape optimization of structures is making a robust link between design model (geometric description) and analysis model. This paper investigates the potential of Isogeometric Analysis (IGA) for solving this problem. The generic framework of shape optimization of structures is presented based on Isogeometric analysis. By discretization of domain via NURBS functions, the a...

Shape Particle Guided Tissue Classification

In many cases, the accuracy of statistical pixel classification can be improved by applying a spatially varying prior that can be derived from a shape model. We propose to represent the prior knowledge on the spatial distribution of tissue classes by a distribution of shape particles, each representing one possible distribution of tissue classes. Classification and shape can then be optimized j...

Shape oscillations of particle-coated bubbles and directional particle expulsion

Bubbles stabilised by colloidal particles can find applications in advanced materials, catalysis and drug delivery. For applications in controlled release, it is desirable to remove the particles from the interface in a programmable fashion. We have previously shown that ultrasound waves excite volumetric oscillations of particle-coated bubbles, resulting in precisely timed particle expulsion d...

Engineering particle trajectories in microfluidic flows using particle shape.

Recent advances in microfluidic technologies have created a demand for techniques to control the motion of flowing microparticles. Here we consider how the shape and geometric confinement of a rigid microparticle can be tailored for 'self-steering' under external flow. We find that an asymmetric particle, weakly confined in one direction and strongly confined in another, will align with the flo...

Equilibrium shape of a buoyant particle

Small particles on supports have been of interest for many years both scientifically and with respect to their uses in heterogeneous catalysis. One of the common and often critical questions is the shape of a small particle, i.e., spherical or faceted, since many of the properties depend upon the relative populations of different surface planes and edges. The question of the equilibrium shape o...
