Two Decades Dynamics of Belt Conveyor Systems

The quest for a useful design tool that incorporated the effect of dynamics of conveyor belts on the design of a conveyor system started halfway the 1950's. It was however not until halfway the 1980's that the first useful design tool became available. In the early days of using dynamics of belt conveyor systems the attention was focused on an analysis of both the starts and the stops of long o...

On Uncalibrated Motion-Based Inspection for Conveyor-Belt Systems

This paper presents an analytical study and several practical results for computing stable reconstructions with uncalibrated, motion-based inspection and conveyor-belt installations. We achieve metric reconstruction with a simple, efficient algorithm and two nonlinear constraints expressing knowledge readily accessible in a real setup. We analyse the stability and accuracy of reconstruction wit...

Coherence properties and quantum state transportation in an optical conveyor belt.

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...

Synaptic Ribbon Conveyor Belt or Safety Belt?

The synaptic ribbon in neurons that release transmitter via graded potentials has been considered as a conveyor belt that actively moves vesicles toward their release sites. But evidence has accumulated to the contrary, and it now seems plausible that the ribbon serves instead as a safety belt to tether vesicles stably in mutual contact and thus facilitate multivesicular release by compound exo...
