A Combined PDR and Wi-Fi Trilateration Algorithm for Indoor Localization
Digital Signal Processing and Signal Processing Education Workshop, 2019Indoor localization using Wi-Fi or pedestrian dead reckoning (PDR) has several limitations in terms of Wi-Fi signal fluctuations and PDR drift errors. To overcome these limitations, we propose a sensor fusion framework for Wi-Fi and PDR systems.

Pedestrian localization with PDR supplemented by GNSS
Mexican International Conference on Computer Science, 2019Pedestrian localization in urban areas is often inaccurate, because GNSS signals could be blocked, attenuated or reflected by existing obstacles. The use of a combination of GNSS could reduce the drawbacks related to the scenario.

Indoor Localization using PDR with Wi-Fi Weighted Path Loss Algorithm
Information and Communication Technology Convergence, 2019Localization using pedestrian dead reckoning (PDR) and received signal strength indication (RSSI) signals from Wi-Fi enhance the indoor positioning accuracy by reducing the inertial measurement unit (IMU) sensor errors and Wi-Fi RSSI signal fluctuations ...

2017 Formal Methods in Computer Aided Design (FMCAD), 2017
Property Directed Reachability (PDR) is an efficient model checking technique. However, the intrinsic high computational complexity prevents PDR from meeting the challenges of real world verification. To address this problem, this paper introduces the parallel algorithm P3 based on: 1) partitioning of the input problem, 2) exchanging of learned ...

PDR Models – Radiative properties
EAS Publications Series, 2008Some recent results on radiative transfer in standard PDR models (1D, stationary) are presented and illustrated with the Meudon PDR code. It is shown that current modeling capacities are sufficient to go beyond the usual (mostly escape probabilities) approximations. A few more sophisticated works adapted to more complex physical

Two concerns came to mind as I read "The Physicians' Desk Reference [ PDR ]: Problems and Possible Improvements" by Cohen and Insel. 1 The PDR 2 must be viewed as a form of advertising (in a reference format) in which pharmaceutical manufacturers present information on medications that they pick and choose by presenting package insert information ...

A Fusion Algorithm of Indoor Positioning Based on PDR and RSS Fingerprint
IEEE Sensors Journal, 2018The pedestrian dead reckoning (PDR) positioning has small noise and high stability in the short term, but it cannot use for long term because of its cumulative error.

Results of PDR Treatments: The AMC PDR Experience
2013Pulsed-dose-rate (PDR) brachytherapy has been introduced for the treatment of intermediate-/high-risk prostate cancer. A dose of 28–35 Gy PDR brachytherapy is given as a boost to external beam radiotherapy of 46–50 Gy. The reported 5-year biochemical-free survival is 85.6–89.5 %. The incidence of grade 2–3 rectal complications is limited (12–15 %). The
