Radar signal sorting is the core part of electronic support measures, which responsible for deinterleaving overlapping pulse sequences received by receiver from complex environment, separating different radiation source signals, and providing identification. Particle swarm optimization (PSO) a population-based global algorithm with great advantages in intelligent can adapt to electromagnetic en...

We characterize through simulation a microfluidic-based particle sorting approach instrumental in flow cytometry for quantifying microtissue features. The microtissues are represented herein as rigid spheres. The numerical solution employed draws on a Lagrangian–Lagrangian (LL), Smoothed Particle Hydrodynamics (SPH) approach for the simulation of the coupled fluid–rigid-body dynamics. The study...

The main research approaches in Computational Fluid Dynamics (CFD) are grid-based (Euler) or based on particle motion (Lagrange). For interactive fluid simulation, techniques have been developed to use the Graphics Processing Unit (GPU) to speed up the computation using an Eulerian approach. This paper describes an approach for setting up a Lagrangian particle based fluid simulation on the GPU....

Particle systems have long been recognized as an essential building block for detail-rich and lively visual environments. Current implementations can handle up to 10,000 particles in realtime simulations and are mostly limited by the transfer of particle data from the main processor to the graphics hardware (GPU) for rendering. This paper introduces a full GPU implementation of both the simulat...

This paper describes an improved microfluidic device that enables hydrodynamic particle concentration and size-dependent separation to be carried out in a continuous manner. In our previous study, a method for hydrodynamic filtration and sorting of particles was proposed using a microchannel having multiple branch points and side channels, and it was applied for continuous concentration and sep...

The objectives of this research were to describe the feed sorting, feeding behavior, and feed intake of cows consuming a close-up ration and to determine if these behaviors are affected by competition for access to the feed bunk. Thirty-six dry Holstein cows, consuming a close-up total mixed ration diet, were assigned to 1 of 2 treatments: 1) noncompetitive (1 cow/feed bin) or 2) competitive (2...

Porous membranes have been fabricated based on the development of the perforated membrane mold [Y. Luo and R. N. Zare, Lab Chip, 2008, 8, 1688-1694] to create a single filter that contains multiple pore sizes ranging from 6.4 to 16.6 µm inside a monolithic three-dimensional poly(dimethylsiloxane) microfluidic structure. By overlapping two filters we are able to achieve smaller pore size opening...

Sorting of colloidal particles of different sizes is of importance in the transport and delivery of such particles in biological, materials science, and other technological contexts. A successful methodology involves the flow of a mixture of particles over designer surfaces presenting a periodic array of traps (optical tweezers) or microfabricated obstacles. The trajectories of the particles ov...
