A Survey of Latest Wi-Fi Assisted Indoor Positioning on Different Principles
Sensors, 2023 As the location-based service (LBS) plays an increasingly important role in real life, the topic of positioning attracts more and more attention. Under different environments and principles, researchers have proposed a series of positioning schemes and ...

Benefits and Impact of Joint Metric of AOA/RSS/TOF on Indoor Localization Error
Applied Sciences, 2016 The emerging techniques in the Fifth Generation (5G) communication system, like the millimeter-Wave (mmWave) and massive Multiple Input Multiple Output (MIMO), make it possible to measure the Angle-Of-arrival (AOA), Receive Signal Strength (RSS) and Time-

The Value of Observing the Buyer Arrival Time in Dynamic Pricing [PDF]
, 2020 We consider a dynamic pricing problem where a firm sells one item to a single buyer in order to maximize expected revenues. The firm commits to a price function over an infinite horizon.

Time-dependent analysis of virtual waiting time behaviour in discrete time queues [PDF]
, 2005 Discrete time queueing models have been shown previously to be of practical use for modelling the approximate time-dependent behaviour of queue length in systems of the form M(t)/G/c.

A Fractional Programming Method for Target Localization in Asynchronous Networks
IEEE Access, 2018 In this paper, we address the target device localization problem in the asynchronous networks. For the purpose of saving power resources, the target device is not synchronized with the anchor nodes, but is only required to listen to the signals ...

Measurement of time of arrival in quantum mechanics [PDF]
Physical Review A, 1998 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 $Δt_A \sim 1/E_k$, where $E_k$ is the initial kinetic energy of the particle. With a better accuracy, particles reflect off
