Computational Investigation of Multiple Oscillating Hydrofoils and its Effect on Thrust Augmentation [PDF]

MATEC Web of Conferences, 2021
Previous investigations of flapping hydrofoils for the purpose of thrust production have been limited to one or two in tandem. Tandem foils were found to have superior performance because the performance of the aft foil was augmented by the vortices shed

Parameterized Modeling and Calibration for Orbital Error in TanDEM-X Bistatic SAR Interferometry over Complex Terrain Areas

Remote Sensing, 2021
The TerraSAR-X add-on for Digital Elevation Measurements (TanDEM-X) bistatic system provides high-resolution and high-quality interferometric data for global topographic measurement. Since the twin TanDEM-X satellites fly in a close helix formation, they

Simultaneous determination of 10 N-nitrosamines in drinking water by tandem solid phase extraction-gas chromatography tandem mass spectrometry

环境与职业医学, 2022
BackgroundN-nitrosamines, a group of by-products of drinking water disinfection, have strong cytotoxicity to mammals. N-nitrosamines in drinking water are at the ng·L−1 level, and its accurate qualitative and quantitative analysis is difficult, so it is ...
