The features of the propagation dynamic stresses in a conveyor belt, material properties which correspond to Maxwell element model, are considered. Analytical expressions presented for calculating elastic modulus, loss and angle mechanical depending on frequency longitudinal oscillations belt an extended transport conveyor. To analyze stress process, dimensionless parameters introduced that cha...

Light driven molecule traps. Trapping single ions under vacuum allows for precise spectroscopy in atomic physics. However the confinement of biological molecules in bulk water is hindered by the lack of comparably strong forces. Molecules have been immobilized to surfaces, often with detrimental effects on their function. Here, we optically trap molecules by creating the microscale analog of a ...

A system that reconstructs 3D models from a single camera monitoring fish transported on conveyor is investigated. Models are subsequently used for training species classifier and improving estimates of discarded biomass. It demonstrated monocular camera, combined with conveyor's linear motion produces constrained form multiview structure motion, allows the scene to be reconstructed using conve...

Automated optical inspection systems are frequently utilized to sort out defective objects. However, those objects might actually be reworked or disposed. The combination of defect detection and specific processing in a single operation helps to reduce reworking time and waste. Defect detection on 3D objects is approached by combining the techniques of surface detection and geometry estimation....

Passive tracers are used in an o€-line version of the United Kingdom Fine Resolution Antarctic Model (FRAM) to highlight features of the circulation and provide information on the inter-ocean exchange of water masses. The use of passive tracers allows a picture to be built up of the deep circulation which is not readily apparent from examination of the velocity or density ®elds. Comparison of o...

Crushers play an important role in the comminution of minerals and the control of its operation can lead to an increase of the plant throughput and efficiency. This work presents a simple but effective method for controlling a crusher circuit by acting over the feeder and the speed of the conveyor belt carrying out the mineral up to the crusher. Guidelines for tuning the strategy, as well as pr...

This paper explores a method of manipulating a planar rigid part on a conveyor belt using a robot with just one joint. This approach has the potential of offering a simple and flexible method for feeding parts in industrial automation applications. In this paper we develop a model of this system and of a variation which requires no sensing. We have been able to characterize these systems and to...

Journal of Digital Information Management Volume 9 Number 6 December 2011 ABSTRACT: In order to control reasonably the acceleration and dynamic tension in full-load starting process of conveyor system, accurate design techniques should be adopted. This paper selects the viscoelasticity model suiting to the belt by comparing dynamic performance of some kinds of models, and develops simulation mo...

There has been much debate as to the relative merits of belt conveyors with ploughs vs. chain-slat conveyors with gates for this application. There are experienced engineers in strong support of each alternative. In many cases, the strength of the support for one type is due to bad experience with a poorly designed or under-capacity conveyor of the other. Unfortunately, the majority of conveyor...

We have prepared and detected quantum coherences of trapped cesium atoms with long dephasing times. Controlled transport by an "optical conveyor belt" over macroscopic distances preserves the atomic coherence with slight reduction of coherence time. The limiting dephasing effects are experimentally identified, and we present an analytical model of the reversible and irreversible dephasing mecha...
