Conveyor belt clock synchronization [PDF]
Physical 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.

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

Existence and Hardness of Conveyor Belts [PDF]
The Electronic Journal of Combinatorics, 2020 An open problem of Manuel Abellanas asks whether every set of disjoint closed unit disks in the plane can be connected by a conveyor belt, which means a tight simple closed curve that touches the boundary of each disk, possibly multiple times. We prove three main results: For unit disks whose centers are both $x$-monotone and $y$-monotone, or whose ...

Sound-Based Improved DenseNet Conveyor Belt Longitudinal Tear Detection
IEEE 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 ...

Chaos on the conveyor belt [PDF]
Physical Review E, 2013 The dynamics of a spring-block train placed on a moving conveyor belt is investigated both by simple experiments and computer simulations. The first block is connected by spring to an external static point, and due to the dragging effect of the belt the blocks undergo complex stick-slip dynamics.

Can climate models capture the structure of extratropical cyclones? [PDF]
, 2006 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 energy-saving optimal control method of belt conveyor in coal mine
Gong-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.
