Arrival and departure manager cooperation for reducing airborne holding times at destination airports [PDF]

open access: yes, 2011
This thesis addresses the possibility of using a delay-on-ground concept in which flights with less than 1 hour flying time (often referred to as pop-up flights) absorb their arrival sequencing delay at the departure gate by being issued their Arrival ...

Angle of arrival estimation for broadband signals : a comparison [PDF]

open access: yes, 2013
This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix ...

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 ...

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.

A Fractional Programming Method for Target Localization in Asynchronous Networks

open access: yesIEEE 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 ...

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.

The Value of Observing the Buyer Arrival Time in Dynamic Pricing [PDF]

open access: yes, 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]

open access: yes, 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.

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 ...
