Abstract: With the use of the global positioning system, World Geodetic System 1984 (WGS84) [or The International Terrestrial Reference Frame (ITRF)] has been widely accepted as a global geodetic reference system and adopted by many ...

Abstract: This research aims to develop an alternative solution to computing the three-axis orientations of a tunnel-boring machine (TBM) during microtunneling and pipe-jacking operations. Comprehensive geometric foundations are ...

Abstract: Our research has investigated the feasibility of directly sourcing autonomous operations data from a construction-vehicle positioning system, so as to enable productivity analysis and simulation modeling in the practical ...

Abstract: This research aims to develop an automated and cost-effective solution to guide the advance of a tunnel-boring machine (TBM) during microtunneling and pipe jacking operations. Pros and cons of currently available TBM ...

Abstract: Extreme natural hazards pose huge challenges to public administration. In the era of social media, governmental response takes the form of complex adaptive systems, applying information technology to support public ...

Abstract: In southeast China, along the northern coast of the Hangzhou Bay from Ganpu to Jinshan, there is a stable deep channel, the Northern Channel, which is suitable for harbor construction and navigation. The possible siltation ...

Abstract: Experiments were carried out in a wave flume on internal solitary wave (ISW) of depression-type propagating over a submarine ridge in triangular shape. Tests were arranged in series from ...
