China possesses a vast territory, and the manual harvesting of blueberries is time-consuming labor-intensive. Due to planting agronomy differences in other countries, needs develop domestic blueberry harvester realize mechanical harvesting. In process, “collision” core problem. Most literature has studied rigid body–rigid body collision, while few authors have rigid–flexible coupling collision ...

The aim of this paper is the variational study of the contact with adhesion between an elastic material and a rigid foundation in the quasistatic process where the deformations are supposed to be small. The behavior of this material is modelled by a nonlinear elastic law and the contact is modelled with Signorini’s conditions and adhesion. The evolution of bonding field is described by a nonlin...

Our generation has seen unprecedented advances in electromagnetic wave technology such as the microwave oven, the cellular telephone, and the magnetic resonance imager, each a creative exploitation of an invisible electromagnetic signal that was initially met with rigid skepticism. The modern bone growth stimulators that employ pulsed electromagnetic fields (PEMFs) have been available for 20 ye...

Image-based servozng systems are often used to track moving targets and their underlying control architecture is a regulation of the image. This regulation is a function of rigid camera-to-target geometric constraints. Satisfying such constraints requires that the robot motors have suficient velocity bandwidths, and oflen these bandwidths are limited. This paper lays down the foundation for a p...
