We developed a data assimilation method that incorporates the microwave imager (MWI) brightness temperatures (TBs) into the cloud-resolving model (CRM) developed by the Japan Meteorological Agency (JMANHM). This method consisted of a displacement error correction scheme and an Ensemble-based variational assimilation scheme. In the displacement error correction scheme, we obtained the optimum di...

Bridge displacement is the most basic evaluation index of the health status of a bridge structure. The existing measurement methods for bridge displacement basically fail to realize long-term and real-time dynamic monitoring of bridge structures, because of the low degree of automation and the insufficient precision, causing bottlenecks and restriction. To solve this problem, we proposed a brid...

This paper introduces a kind of measurement method of the displacement for the liquid level by the use of the laser triangulation and the angular displacement tracking. Based on the principle of the laser reflection and the principle of the source synchronous tracking, according to the triangulation method and the optoelectronic matrix imaging technology, it realize the corresponding relationsh...
