Conveyor-belt clock synchronization [PDF]

open access: yesPhysical Review A, 2004
A protocol for synchronizing distant clocks is proposed that does not rely on the arrival times of the signals which are exchanged, and an optical implementation based on coherent-state pulses is described. This protocol is not limited by any dispersion that may be present in the propagation medium through which the light signals are exchanged ...

A minimalistic and optimized conveyor belt for neutral atoms. [PDF]

open access: yesSci Rep, 2017
Here we report of a design and the performance of an optimized micro-fabricated conveyor belt for precise and adiabatic transportation of cold atoms. A theoretical model is presented to determine optimal currents in conductors used for the transportation.

Vortex conveyor belt for matter-wave coherent splitting and interferometry. [PDF]

open access: yesSci Rep, 2019
We numerically study a matter wave interferometer realized by splitting a trapped Bose-Einstein condensate with phase imprinting. We show that a simple step-like imprinting pattern rapidly decays into a string of vortices that can generate opposite ...

Influence of the elastic modulus of a conveyor belt on the power allocation of multi-drive conveyors. [PDF]

open access: yesPLoS ONE, 2020
The implementation of multiple drives for belt conveyors can solve the problems associated with motor overpower and the excessive tension of conveyor belts powered by a single drive.

Sound-Based Improved DenseNet Conveyor Belt Longitudinal Tear Detection

open access: yesIEEE Access, 2022
At present, conveyor belt tearing is the most serious fault of belt conveyor, causing the greatest loss. This paper aims to overcome the issues of poor accuracy, low precision, and poor real-time performance in the longitudinal tear detection of the ...

Research on energy-saving optimal control method of belt conveyor in coal mine

open access: yesGong-kuang zidonghua, 2022
Due to the discontinuity of coal production, the belt conveyor is often in the running state of no-load, light load and rarely full load. This causes a waste of electricity and exacerbates the wear and tear of equipment.

Can climate models capture the structure of extratropical cyclones? [PDF]

open access: yes, 2009
Composites of wind speeds, equivalent potential temperature, mean sea level pressure, vertical velocity, and relative humidity have been produced for the 100 most intense extratropical cyclones in the Northern Hemisphere winter for the 40-yr ECMWF Re ...

Research on intelligent monitoring system of mine-used belt conveyor

open access: yesGong-kuang zidonghua, 2020
In view of the friction and heating between conveyor belt and key components such as idlers and rollers, the internal damage and tear of steel conveyor belt, and high running power consumption in operation process of mine-used belt conveyor, an ...
