Surface Wave Investigation and Monitoring (SWIM) will be launched on board the Chinese French Ocean SATellite (CFOSAT) in 2018. This paper proposes a joint method to simultaneously retrieve wave spectra at different scales from spaceborne Synthetic Aperture Radar (SAR) and CFOSAT SWIM wave spectrometer data. The method combines the output from the two different sensors to overcome retrieval limitations...
China launched two new spaceborne microwave sensors in August and September 2016. One is the C band multi-polarization high resolution synthetic aperture radar (SAR) on board satellite GF-3. The other is the Ku band wide swath Interferometric Imaging Radar Altimeter (InIRA) on board space laboratory TG-2. This paper gives some preliminary results for the quantitative remote sensing of ocean winds...
As is well known, earthquake often inflicts severe casualties and property losses. The occurrence of earthquakes cannot be reliably predicted by current technology, therefore the earthquake emergency and rescue is an important part of protecting against and mitigating earthquake disasters. Basic geographical data play an important role in earthquake emergency work. However, it is hard to acquire the...
As one of the most powerful air-sea interactions in the weather system, a typhoon usually accompanies with a wide range of heavy rainfall. Due to the influence of rainfall on the radar signal, the inversion precision of sea surface wind field from space-borne radar declines. In this paper, based on C band scatterometer rain effect model and Synthetic Aperture Radar (SAR) rainfall backscattering model,...
The Interferometric Imaging Radar Altimeter (InIRA) is a new generation radar altimeter developed by China, which combines the function of interferometric radar altimeter and Synthetic Aperture Radar (SAR). In this paper, we explored the retrieval method of wind speed from simulated InIRA echoes. The combined significant wave height (Hs) was first statistically derived from sea surface height (SSH),...
In 2004, Innopower began the R&D work to develop saturated iron core type SFCL. The initial reasons to choose this technology are to avoid the direct impact by the quench of the superconductor coils during fault current limiting, which results in long recovery time and complicated protection requirement. The saturated iron core type SFCL have been proved to be practical and suitable for utility...
Building an automated, intelligent, informationized integrated maintenance support information system (IMSIS) for aviation equipment is an important guarantee to enhance combat effectiveness. Having analyzed the characteristics of the aviation equipment support of the advanced countries, we built up IMSIS support system, analyzed the functional components of the system and the goals to achieve, put...
The recombinant single-chain trispecific antibody against three toxins including Okadaic acid (OA), saxitoxin (STX) and tetrodotoxin (TTX) was developed. Three single-chain variable fragment (ScFv) genes were linked via linkers (Gly4-Ser)3 to construct fusion ScFv gene OST-ScFv through splicing by overlapping extension. Fusion gene OST-ScFv was 2 256 bp, encoding 752 amino acids, and was inserted...
The following results are obtained based on the study of in-situ stress measurements using stress relief by overcoring technique and stability of surrounding rock masses in the some deeply buried metal mine: (1) the dominative stress at depth of 820m is tectonic stress and the maximum principal stress is 28.1MPa. The principal stress dispersion is 21.4MPa very big and which is apt to cause the rib...
In order to prevent particle swarm optimization from being trapped in local optima, a new vector called the weighted individual best position of the other particles is introduced. On the one hand, the behavior of each particle is not only influenced by its own best position and the global best position but also by the individual best positions of the others in the swarm. On the other hand, fitness...
