A Timely Arrival

2000
Abstract When, at two o’clock in the afternoon on the next day, Natividade boarded the trolley to go on I don’t know what shopping errands at the Rua do Ouvidor, she carried the phrase with her. The view of the bay did not distract her, nor the people passing by, nor the bumps of the street, nothing.

A comparison of prehospital estimated time of arrival and actual time of arrival to an emergency department

The American Journal of Emergency Medicine, 1990
The accuracy of the paramedic's estimated time until arrival (ETA) to an emergency department has never been studied. Two hundred and eighty paramedic runs were prospectively studied in a suburban, residency-affiliated emergency department. The average ETA was 7.39 +/- 3.72 minutes.

Considering Zero-Arrival Time and Block-Arrival Time in Hierarchical Functional Timing Analysis

2006
Timing analysis of complex state-of-the-art designs demands efficient algorithms able to cope with design complexity. Exploring the hierarchical information generally encountered in complex designs became mandatory to perform functional timing analysis (FTA) in acceptable execution times.

Space-time localization using times of arrival

2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
We provide a computationally efficient framework for utilizing Time of Arrival (ToA) sensors to localize multiple events in close proximity in space and time. Conventional ToA-based localization algorithms are typically designed for single events. Na¨ive approaches for associating ToAs with events and then applying a conventional localization algorithm

Maximizing the Probability of Arriving on Time

2013
We study the problem of maximizing the probability of arriving on time in a stochastic network. Nodes and links in the network may be congested or uncongested, and their states change over time and are based on states of adjacent nodes. Given a source, destination, and time limit, the goal is to adaptively choose the next node to visit to maximize the ...

On Time-of-arrival Positioning in a Multipath Environment

IEEE Transactions on Vehicular Technology, 2005
Wireless geolocation in a multipath environment is of particular interest for wideband communications and fast-developing ultrawideband (UWB) technologies. Conventional methods are solely based on first arriving signals. In this paper, it is investigated whether and under what conditions processing delay estimates of multipath components in addition to

Time-of-arrival estimation for blind beamforming

2013 18th International Conference on Digital Signal Processing (DSP), 2013
Ad-hoc arrays formed by mobile devices are increasingly available to capture audio and video in social events. Using spatial signal processing algorithms, e.g., beamforming, with microphone signals of such arrays is hindered by the unknown locations of the devices and the lack of temporal synchronization between them. While self-calibration methods can

Arriving-on-Time Problem

Transportation Research Record: Journal of the Transportation Research Board, 2006
Finding optimal paths in stochastic networks is an important topic in many scientific and engineering fields. To cope with uncertainty, various performance measures, including expected travel time, reliability, value at risk, and expectation with chance constraint, have been introduced. The literature has shown that adaptive strategies that incorporate

Time of arrival and Time Sum of arrival based NLOS identification and localization

2012 IEEE 14th International Conference on Communication Technology, 2012
Non-Line of Sight (NLOS) error due to the blockage of direct paths has been considered as the major problem in the wireless localization. Therefore, this paper studies the influence on different algorithms caused by the same NLOS error in order to identify LOS base stations (BS) from NLOS BS. Specifically, Time of Arrival (TOA) based algorithm and Time
