Physicists find direct evidence of strong electron correlation in a 2D material for the first time（图）
二维材料 强电子 相关性 非常规超导性
2022/3/17
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-f...
Static program checking tools can find many serious bugs in software, but due to analysis limitations they also frequently emit false error reports. Such false positives can easily render the error ch...
With the successful implementation of the Wide Area Augmentation System (WAAS) for the North America, there is interest in implementing similar systems in other parts of the world. The ionosphere over...
Linear Time-of-Arrival Estimation in a Multipath Environment by Inverse Correlation Method
Linear Time-of-Arrival Estimation Multipath Environment Inverse Correlation Method
2015/6/26
The Maximum Likelihood Estimator (MLE) is most often used to estimate the signal time delay in a multipath en vironment. There are various implementations of the MLE which can be divided into the time...

To fulfill the envisioned role of a backup navigation system to the GPS, Loran needs to satisfy the user requirements of accuracy, integrity, continuity, and availability. The biggest obstacle to accu...
Correlation of GPS signal fades due to ionospheric scintillation for aviation applications
Ionospheric scintillation Global Positioning System (GPS) Wide Area Augmentation System (WAAS) Aviation Availability
2015/6/24
Deep and frequent Global Positioning System (GPS) signal fading due to strong ionospheric scintillation is a major concern for GPS-guided aviation in equatorial areas during high solar activity. A GPS...
