Optical sorting, as one kind of optical tweezers, is used to separate mixed particles in a background environment. This unusual tool has wide application prospect because the non-contact and non-destructive advantages ideally suit pressing need bio-technology. However, most sorting methods devices have been accomplished based on real-time one-by-one which ignored efficiency not applicable high-...

Mixed-model assembly lines are increasingly accepted in many industrial environments to meet the growing trend of greater product variability, diversification of customer demands, and shorter life cycles. In this research, a new mathematical model is presented considering balancing a mixed-model U-line and human-related issues, simultaneously. The objective function consists of two separate com...

We present a nanoparticle size-separation device based on nanofluidic rocking Brownian motor. It features ratchet-shaped electrostatic particle potential with increasing barrier heights along the transport direction. The sharp drop of current height is exploited to separate suspension into multiple subpopulations. By solving Fokker-Planck equation, we show that physics separation mechanism gove...

Abstract In the original Predicted Particle Properties (P3) bulk microphysics scheme, all ice-phase hydrometeors are represented by one or more “free” ice categories, where physical properties evolve smoothly through changes to four prognostic variables (per category), and with a two-moment representation of particle size distribution. As such, spectral dispersion cannot independently, which th...

BACKGROUND The transport of particles in surrogate and actual arterial geometries has been investigated synergistically by experimentation and numerical simulation. The motivating application for this work is orbital atherectomy which spawns a particle cloud in the process of debulking plaque from arterial walls. METHODS Paired simulations and experiments were performed to prove the capabilit...
