Differentiability of the arrival time [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2015
For a monotonically advancing front, the arrival time is the time when the front reaches a given point. We show that it is twice differentiable everywhere with uniformly bounded second derivative.

Time of Arrival from Bohmian Flow [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2002
We develop a new conception for the quantum mechanical arrival time distribution from the perspective of Bohmian mechanics. A detection probability for detectors sensitive to quite arbitrary spacetime domains is formulated.

Measurement of Time-of-Arrival in Quantum Mechanics [PDF]

open access: yesPhysical Review A, 1997
It is argued that the time-of-arrival cannot be precisely defined and measured in quantum mechanics. By constructing explicit toy models of a measurement, we show that for a free particle it cannot be measured more accurately then $\Delta t_A \sim 1/E_k$,

Confined Quantum Time of Arrivals [PDF]

open access: yesPhysical Review Letters, 2005
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.

Times of arrival: Bohm beats Kijowski [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2005
We prove that the Bohmian arrival time of the 1D Schroedinger evolution violates the quadratic form structure on which Kijowski's axiomatic treatment of arrival times is based. Within Kijowski's framework, for a free right moving wave packet, the various

Times of arrival and gauge invariance [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
We revisit the arguments underlying two well-known arrival-time distributions in quantum mechanics, viz., the Aharonov–Bohm–Kijowski (ABK) distribution, applicable for freely moving particles, and the quantum flux (QF) distribution. An inconsistency in the original axiomatic derivation of Kijowski’s result is pointed out, along with an inescapable ...

Performance Comparison of ToA and TDOA Based Tracking In Underwater Multipath Environments Using Bernoulli Filter

open access: yesPolish Maritime Research, 2023
Underwater localization and tracking is a challenging problem and Time-of-Arrival and Time-Difference-of-Arrival approaches are commonly used. However, the performance difference between these approaches is not well understood or analysed adequately ...

Cooperative positioning using angle of arrival and time of arrival [PDF]

open access: yes2014 Sensor Signal Processing for Defence (SSPD), 2014
Localization has been one of the most highly researched topics in wireless communications in the past decade. Localization of wireless nodes can be achieved using a variety of techniques, in which range measurement and angle measurement are most commonly used. In the presence of both angle and range measurement, a hybrid model can be developed. In this
