Particle tracking in the ILC extraction lines with DIMAD and BDSIM [PDF]
, 2005 The study of beam transport is of central importance to the design and performance assessment of modern particle accelerators. In this paper, we benchmark two contemporary codes, DIMAD and BDSIM, the latter being a relatively new tracking code built ...

Modulation Particle Tracking [PDF]
Biophysical Journal, 2010 In this study, we present a novel optical imaging method that makes use of high precision particle tracking of fluorescent particles to obtain images of nanometer size structures in live cells. Particle tracking not only provides the trajectory of the center of mass but also the particle orientation and size can now be observed, in vivo and real time ...

Combining Particle Filter and Population-based Metaheuristics for Visual Articulated Motion Tracking
ELCVIA Electronic Letters on Computer Vision and Image Analysis, 2005 Visual tracking of articulated motion is a complex task with high computational costs. Because of the fact that articulated objects are usually represented as a set of linked limbs, tracking is performed with the support of a model.

Magnetic particle tracking: A semi-algebraic solution
Chemical Engineering Science, 2023 Magnetic Particle Tracking (MPT) is a relatively new non-invasive measurement technique which is often used to study dense granular flow. Its basic principle relies on tracking the movement of a single magnetic tracer by means of measuring the magnetic field strength at a suitable distance from the tracer. By assumption of a magnetic dipole and the use

Modeling Environmental DNA Transport in the Coastal Ocean Using Lagrangian Particle Tracking
Frontiers in Marine Science, 2019 A number of studies have illustrated the utility of environmental DNA (eDNA) for detecting marine vertebrates. However, little is known about the fate and transport of eDNA in the ocean, thus limiting the ability to interpret eDNA measurements.

Tracking shocked dust: state estimation for a complex plasma during a shock wave
, 2011 We consider a two-dimensional complex (dusty) plasma crystal excited by an electrostatically-induced shock wave. Dust particle kinematics in such a system are usually determined using particle tracking velocimetry.

Two-frame 3D particle tracking [PDF]
Measurement Science and Technology, 2006 A whole-field three-dimensional (3D) particle tracking velocimetry (PTV) tool for diagnostics in fluid mechanics is presented. Specifically, it is demonstrated why and when PTV is the natural choice in 3D applications compared to particle image velocimetry (PIV).
