SChina20: A Stable Geodetic Reference Frame for Ground Movement and Structural Deformation Monitoring in South China
Publisher: ASCE
Abstract: We have established a stable regional geodetic reference frame, designated as SChina20, using approximately 10-year observations (2010–2019) at 40 Global Navigation Satellite System (GNSS) sites in South China. The regional ...
Comparisons of Ground-Based and Building-Based CORS: A Case Study in the Region of Puerto Rico and the Virgin Islands
Publisher: American Society of Civil Engineers
Abstract: This study investigated long-term observations from three pairs of closely spaced, continuously operating reference stations (CORS): STVI and VITH (2008–2014, 0.6 km apart), BYSP and PRHL (2008–2014, 3.2 km apart), and ...
Millimeter-Accuracy Structural Deformation Monitoring Using Stand-Alone GPS: Case Study in Beijing, China
Publisher: American Society of Civil Engineers
Abstract: Structural monitoring and engineering surveys that use the Global Positioning System (GPS) have traditionally performed using a so-called carrier-phase double-difference method in data processing. The method requires at ...
Delineating Beach and Dune Morphology from Massive Terrestrial Laser-Scanning Data Using <i>Generic Mapping Tools</i>
Publisher: American Society of Civil Engineers
Abstract: Terrestrial laser-scanning (TLS) techniques have been proven to be efficient tools for collecting three-dimensional high-density and high-accuracy point clouds for coastal research and resource management. However, TLS ...
Numerical Investigation of Effects of Turbulence Intensity on Aerodynamic Performance for Straight-Bladed Vertical-Axis Wind Turbines
Publisher: ASCE
Abstract: Vertical-axis wind turbines (VAWTs) may be subjected to varying degrees of turbulence in practice. In the present study, the computational fluid dynamics (CFD) method and improved delayed detached eddy simulation (IDDES) ...
