Time-of-arrival distribution for arbitrary potentials and Wigner's time-energy uncertainty relation [PDF]
, 1999 A realization of the concept of "crossing state" invoked, but not implemented, by Wigner, allows to advance in two important aspects of the time of arrival in quantum mechanics: (i) For free motion, we find that the limitations described by Aharonov et ...

Effects of arrival time errors on traveltime tomography [PDF]
Geophysical Journal International, 2000 Summary The ISC Bulletin is the most widely used data set for traveltime tomography since it comprises the largest collection of arrival times. The large number of stations and events gives the best ray path coverage of the Earth’s mantle currently available, but the data also contain a considerable amount of noise.

Direct Position Determination of Multiple Radio Signals
EURASIP Journal on Advances in Signal Processing, 2005 The most common methods for position determination of radio signal emitters such as communications or radar transmitters are based on measuring a specified parameter such as angle of arrival (AOA) or time of arrival (TOA) of the signal.

Self-Calibration for the Time Difference of Arrival Positioning
Sensors, 2020 The time-difference-of-arrival (TDOA) self-calibration is an important topic for many applications, such as indoor navigation. One of the most common methods is to perform nonlinear optimization.

Indoor Carrier Phase Positioning Technology Based on OFDM System
Sensors, 2021 Carrier phase measurement is a ranging technique that uses the receiver to determine the phase difference between the received signal and the transmitted signal. Carrier phase ranging has a high resolution; thus, it is an important research direction for

Optimal source localization problem based on TOA measurements [PDF]
Serbian Journal of Electrical Engineering, 2017 Determining an optimal emitting source location based on the time of arrival (TOA) measurements is one of the important problems in Wireless Sensor Networks (WSNs). The nonlinear least-squares (NLS) estimation technique is employed to obtain the

Mind the Gap – Passenger Arrival Patterns in Multi-agent Simulations [PDF]
, 2016 In most studies mathematical models are developed finding the expected waiting time to be a function of the headway. These models have in common that the proportion of passengers that arrive randomly at a public transport stop is less as headway in ...
