Analytical algorithm for longitudinal deformation profile of a deep tunnel

Journal of Rock Mechanics and Geotechnical Engineering, 2021
To investigate the longitudinal deformation profile (LDP) of a deep tunnel in non-hydrostatic condition, an analytical model is proposed in our study. In this model, the problem is considered as a superposition of two partial models, and the displacement

Development of a Semi-Analytical Algorithm for the Retrieval of Suspended Particulate Matter from Remote Sensing over Clear to Very Turbid Waters

Remote Sensing, 2016
Remote sensing of suspended particulate matter, SPM, from space has long been used to assess its spatio-temporal variability in various coastal areas. The associated algorithms were generally site specific or developed over a relatively narrow range of ...

Chlorophyll-a concentrations inversion based on the modified Quasi-Analytical Algorithm and Sentinel-3 OLCI in Daihai Lake, China

Water supply : the review journal of the International Water Supply Association, 2021
The Quasi-Analytical Algorithm (QAA) is effective in retrieving water inherent optical properties (IOPs) from remote sensing spectral reflectance and has wider applications in studies of the open ocean and coastal waters than of inland waters.
