Quantum optical time-of-arrival model in three dimensions

, 2004
We investigate the three-dimensional formulation of a recently proposed operational arrival-time model. It is shown that within typical conditions for optical transitions the results of the simple one-dimensional version are generally valid.

Operational Time of Arrival in Quantum Phase Space [PDF]

, 1999
An operational time of arrival is introduced using a realistic position and momentum measurement scheme. The phase space measurement involves the dynamics of a quantum particle probed by a measuring device.

Contributed Review: Source-localization algorithms and applications using time of arrival and time difference of arrival measurements [PDF]

Review of Scientific Instruments, 2016
Locating the position of fixed or mobile sources (i.e., transmitters) based on measurements obtained from sensors (i.e., receivers) is an important research area that is attracting much interest. In this paper, we review several representative localization algorithms that use time of arrivals (TOAs) and time difference of arrivals (TDOAs) to achieve ...

The quality of pre-announcement communication and the accuracy of estimated arrival time in critically ill patients, a prospective observational study

BMC Emergency Medicine, 2022
Background Efficient communication between (helicopter) emergency medical services ((H)EMS) and healthcare professionals in the emergency department (ED) is essential to facilitate appropriate team mobilization and preparation for critically ill patients.

The Ulysses Supplement to the BATSE 3B Catalog of Cosmic Gamma-Ray Bursts [PDF]

, 1998
We present Interplanetary Network localization information for 218 gamma-ray bursts in the 3rd BATSE catalog, obtained by analyzing the arrival times of these bursts at the Ulysses and Compton Gamma-Ray Observatory (CGRO) spacecraft.

An Aerial Target Localization Method Using TOA and AOA Measurements with GEO-UAV Bistatic Configuration

Advances in Electrical and Computer Engineering
Based on multi-station spatial diversity capability, GEO-UAV distributed radar could achieve high-precision aerial target localization with the single-transmitting and multiple-receiving configuration. However, the actual observation area can hardly be

Lightning Mapping: Techniques, Challenges, and Opportunities

IEEE Access, 2020
Despite the significant progress in the understanding of the phenomenon of lightning and the physics behind it, locating and mapping its occurrence remain a challenge. Such localization and mapping of very high frequency (VHF) lightning radiation sources

The solution to the problem of time in quantum gravity also solves the time of arrival problem in quantum mechanics

New Journal of Physics, 2022
We introduced with coauthors some years ago a solution to the problem of time in quantum gravity which consists in formulating the quantum theory in terms of real clocks.

Comment on "Measurement of time of arrival in quantum mechanics"

, 2000
The analysis of the model quantum clocks proposed by Aharonov et al. [Phys. Rev. A 57 (1998) 4130 - quant-ph/9709031] requires considering evanescent components, previously ignored.

A Renewal version of the Sanov theorem [PDF]

, 2014
Large deviations for the local time of a process $X_t$ are investigated, where $X_t=x_i$ for $t \in [S_{i-1},S_i[$ and $(x_j)$ are i.i.d.\ random variables on a Polish space, $S_j$ is the $j$-th arrival time of a renewal process depending on $(x_j)$.
