Data assimilation experiment of precipitable water vapor observed by a hyper-dense GNSS receiver network using a nested NHM-LETKF system

Earth, Planets and Space, 2018
We studied the assimilation of high-resolution precipitable water vapor (PWV) data derived from a hyper-dense global navigation satellite system network around Uji city, Kyoto, Japan, which had a mean inter-station distance of about 1.7 km. We focused on

How much can horizontal head movements influence the real-ear measurement accuracy of open-canal fittings?

, 2010
The modified pressure with stored equalisation (MPSE) method of soundfield equalisation is universally recommended for use in clinical practice during the real-ear measurement (REM) verification of open-canal (OC) hearing aids.

HORIZONTAL MERGERS FOR BUYER POWER [PDF]

Salant et al. (1983) showed in a Cournot setting that horizontal mergers are unprofitable because outsiders react by increasing their output. We show that this negative effect may be compensated by the positive effect that horizontal mergers have on the ...

Method for Improved Performance of Fixed-Gain Self-Alignment in the Temperature Stabilizing State

Sensors, 2020
Self-alignment (or initial alignment) is the process by which the Inertial Navigation System (INS) is aligned using only measurements from the inertial sensors and the reference navigation information in the stationary state.
