Fabrication of Pdop/Ag/Pdop Film on NiTi Alloys for Enhancing Their Corrosion Resistant and Antibacterial Properties

Science of Advanced Materials, 2019
NiTi alloys have been intensively applied in biomedical fields because of their unique intrinsic properties. However, the high content of nickel of NiTi alloys is the major concern on their applications of biomedical fields. In addition, the postoperative infections still may be occurred due to the intrinsic unsatisfied antibacterial activity of NiTi.

Effect of PDOP on performance of Kalman Filters for GNSS-based space vehicle position estimation

GPS Solutions, 2017
A theoretical performance analysis of Kalman Filters for Global Navigation Satellite System GNSS-based space vehicle position estimation in varying Position Dilution of Precision (PDOP) conditions is presented. The PDOP indicates the possible accuracy of GNSS measurements using Least Square Estimation (LSE).

PDOP-Based Receiver Selection Algorithm for Target Localization in PCL System

2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019
Passive Coherent Location (PCL) system is a field of radar systems that exploits non-cooperative illuminator of opportunity to detect and track a target. Due to bistatic configuration of PCL system, the locations of transmitter and receiver with respect to a target are important to target estimation accuracy.

Minimum of PDOP and its applications in inter-satellite links (ISL) establishment of Walker-δ constellation

Advances in Space Research, 2014
Abstract Within the next decade, there will be a number of GNSS (Global Navigation Satellite System) available, i.e. modernized GPS, Galileo, restored GLONASS, BeiDou and many other regional GNSS augmentation systems. Thus, measurement redundancies and geometry of the satellites can be improved.
