Dynamic modelling of hepatitis C virus transmission among people who inject drugs: a methodological review [PDF]
, 2014 Equipment sharing among people who inject drugs (PWID) is a key risk factor in infection by hepatitis C virus (HCV). Both the effectiveness and cost-effectiveness of interventions aimed at reducing HCV transmission in this population (such as opioid ...

Microflow valve control system design [PDF]
, 2011 A design synthesis for a microflow control system is presented based on the interrogation of an analytical model, testing, and observation. The key issues relating to controlling a microflow using a variable geometry flow channel are explored through the

Epoxy–amine/metal interphases: Influences from sharp needle-like crystal formation [PDF]
, 2007 When epoxy–amine liquid mixtures are applied onto metallic oxide layer, concomitant amine chemical sorption and metallic surface dissolution appear leading to the organo-metallic complex formation.

Large probe arrays for measuring mean and time dependent local oil volume fraction and local oil velocity component distributions in inclined oil-in-water flows [PDF]
, 2013 Arrays of dual-sensor and four-sensor needle conductance probes have been used to measure the mean and time dependent local properties of upward inclined, bubbly oil-in-water flows (also known as dispersed oil-in-water flows) in a 153mm diameter pipe ...

Optimal sampled-data control, and generalizations on time scales [PDF]
, 2015 In this paper, we derive a version of the Pontryagin maximum principle for general finite-dimensional nonlinear optimal sampled-data control problems. Our framework is actually much more general, and we treat optimal control problems for which the state ...

New double indentation technique for measurement of the elasticity modulus of thin objects [PDF]
, 2011 In this paper we introduce a new method to determine the Young's modulus of thin (biological) samples. The method is especially suitable for small objects with a thickness of a few hundred micrometers.

Phoretic Motion of Spheroidal Particles Due To Self-Generated Solute Gradients
, 2010 We study theoretically the phoretic motion of a spheroidal particle, which generates solute gradients in the surrounding unbounded solvent via chemical reactions active on its surface in a cap-like region centered at one of the poles of the particle.

Compaction of anisotropic granular materials : experiments and simulations [PDF]
, 2004 We present both experimental and numerical investigations of compaction in granular materials composed of rods. As a function of the aspect ratio of the particles, we have observed large variations of the asymptotic packing volume fraction in vertical ...
