STUDY ON THE METHOD OF GRAIN HARVESTER HOPPER UNLOADING AND FULL HOPPER SIGNALLING USED

Hopper Lectures-Jkerr

The struggle for gender equality ranks as one of our century's defining movements. This struggle has won women in Canada and around the developed world the right to vote, to own property, to earn an education, and to work outside the home for wages. It has also won them the right to physical safety within their own homes. Where men once had the legal right to beat their wives with a stick no th...

Microfluidic Bead Suspension Hopper

Many high-throughput analytical platforms, from next-generation DNA sequencing to drug discovery, rely on beads as carriers of molecular diversity. Microfluidic systems are ideally suited to handle and analyze such bead libraries with high precision and at minute volume scales; however, the challenge of introducing bead suspensions into devices before they sediment usually confounds microfluidi...

Hopper Bands: Locust Aggregation

Locust swarms cause famine and hunger in parts of Sub-Saharan Africa as they travel across croplands and eat vegetation. Current models start with biological properties of locusts and analyze the macroscopic behavior of the system. These models exhibit the desired migratory behavior, but do so with too many parameters. To account for this, a new model, the Alignment and Intermittent Motion (AIM...

Computer simulation of hopper flow

This paper describes two-dimensional computer simulations of granular flow in plane hoppers. The simulations can reproduce an experimentally observed asymmetric unsteadiness for monodispersed particle sizes, but also could eliminate it by adding a small amount of polydispersity. This appears to be a result of the strong packings that may be formed by monodispersed particles and is thus a noncon...
