Hong Kong's surface visibility has decreased in recent years due to air pollution from rapid social and economic development in the region. In addition to deteriorating health standards, reduced visibility disrupts routine civil and public operations, most notably transportation and aviation. Regional estimates of visibility solved operationally using available ground and satellite-based estima...

A solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. To develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. To achieve the objective, the yield stress is defined by the friction coefficient throu...

Abstract Research on new seismic sources and data has already performed in 2016 to 2017. Four shallow crustal fault were observed surrounding the city of Semarang, capital Central Java Province, Indonesia. The parameters related with mechanism (reverse fault) maximum magnitude prediction (6.5 Mw) for each was also released based 2017 research. Following this research, structural evaluation espe...

Excavator’s main tasks include digging, trenching, and ground leveling at construction sites, as well work efficiency safety can be improved by using an autonomous excavator. A prerequisite step to achieving excavation is obtain a sound perception of the surrounding ground. For this, LiDAR sensor has been widely used scan environment. However, point cloud generated not ideal for surface reconst...
