Timing and probability of arrival for sea lice dispersing between salmon farms

open access: yesRoyal Society Open Science, 2023
Sea lice are a threat to the health of both wild and farmed salmon and an economic burden for salmon farms. With a free-living larval stage, sea lice can disperse tens of kilometres in the ocean between salmon farms, leading to connected sea louse ...

Underground target positioning based on differential error suppression optimization method

open access: yesGong-kuang zidonghua, 2020
In view of problem that positioning accuracy of positioning methods based on time ranging, namely arrival time, one-way ranging, two-way ranging and symmetrical double-sided two-way ranging (SDS-TWR) is disturbed by timing error factors such as clock ...

Variability in Arrival Time of White Storks (Ciconia ciconia L.): Impact of Age, Interindividual Variation, and Global Change

open access: yesFrontiers in Ecology and Evolution, 2022
Global changes are inducing migratory birds to advance their annual cycle. However, changes in the time of arrival at their breeding grounds have significant fitness implications.

Non-linear arrival time tomography

open access: yesAnnals of Geophysics, 1997
The use of 1D or pseudo- 3D ray tracing techniques in linearized tomographic problems leads to solutions for which it is difficult to assess the true resolution and error distribution.

Arrival-Time Detection in Wind-Speed Measurement: Wavelet Transform and Bayesian Information Criteria

open access: yesSensors, 2020
The time-difference method is a common one for measuring wind speed ultrasonically, and its core is the precise arrival-time determination of the ultrasonic echo signal.

Bus arrival time prediction using mixed multi-route arrival time data at previous stop

open access: yesTransport, 2018
The primary objective of this paper is to develop models to predict bus arrival time at a target stop using actual multi-route bus arrival time data from previous stop as inputs. In order to mix and fully utilize the multiple routes bus arrival time data,

Prediction of Bus Arrival Times at Bus Stop

open access: yesInternational Journal of Technology, 2017
Bus arrival time is very important to passengers, not only at the origin terminal but also at every stop. If there is no predicted arrival time at a stop, the headway designed should match the bus frequency at the stop. The uncertainty in bus arrival

Confined Quantum Time of Arrivals [PDF]

open access: yesPhysical Review Letters, 2004
We show that formulating the quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding states that evolve to unitarily collapse at a given point at a definite time. For the spatially confined particle, we show that the problem admits a solution in the form of an eigenvalue problem ...
