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.

On ‘arriving on time’, but what is ‘on time’? [PDF]

open access: yesGeoforum, 2006
The time-geographical concept of coupling constraints, which deWne when, where and for how long individuals have to join other individuals and material objects, can be useful to ‘time squeeze’ studies. Geographers have typically operationalised the ‘when’ dimension of coupling constrains through arrival times at locations in physical space or the ...

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

Probabilistic Time of Arrival Localization [PDF]

open access: yesIEEE Signal Processing Letters, 2019
In this paper, we take a new approach for time of arrival geo-localization. We show that the main sources of error in metropolitan areas are due to environmental imperfections that bias our solutions, and that we can rely on a probabilistic model to learn and compensate for them.

Correlation between RF signal first-arrival and minimum spectral transit time in cancellous bone

open access: yes, 2023
Measurement of the singular ultrasound velocity of a homogeneous sample may be calculated by division of its thickness and propagation transit time, generally utilizing a detection criterion of an RF signal's first-arrival.

A timely arrival for genomic medicine [PDF]

open access: yesGenetics in Medicine, 2011
In this issue of GIM,1 we describe a young boy who presented with unusually aggressive inflammatory bowel disease refractory to medical and surgical treatment. To reach a diagnosis, we were compelled to use genomic technology that, at the time, was not a clinically validated test.
