RISDomain Ontology for Utility Infrastructure: Coupling the Semantics of CityGML Utility Network ADE and Domain Glossaries
Publisher: ASCE
Abstract: With the utility infrastructure domain becoming more technologically advanced with the modeling of all types of information across varying sectors, it is imperative to develop a domain ontology to enable the interoperability ...
Experimental Study of Filtration Performance of Disc Filter with Discrete Channel Structure
Publisher: ASCE
Abstract: The large head loss of the disc filter has always been one of its main limiting factors, which may affect its working efficiency and service life. Disc flow channel structure is an important factor affecting the performance ...
GIS-Based Information System for Automated Building Façade Assessment Based on Unmanned Aerial Vehicles and Artificial Intelligence
Publisher: ASCE
Abstract: Unmanned aerial vehicles (UAVs) have recently become popular in building façade inspections to maintain a safe and well-performed built environment. A camera-equipped UAV system can capture numerous high-resolution façade ...
Experimental Study on Capillary Water Absorption Performance of Coral Sand Concrete in High-Salt Environment
Publisher: American Society of Civil Engineers
Abstract: The high-salt fog environment under a marine climate affects the capillary water absorption performance of porous building materials, causing changes in the thermal and wet properties of the materials and in their structural ...
A Learning Variable Structure Controller of a Flexible One-Link Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, tip regulation of a flexible one-link manipulator by Learning Variable Structure Control (LVSC) is investigated. Switching surface is designed according to a selected reference ...
A Gain Scheduled Sliding Mode Control Scheme Using Filtering Techniques With Applications to Multilink Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a gain scheduled sliding mode control (SMC) scheme is proposed for tracking control tasks of multilink robotic manipulators. In the new scheme, filtering techniques play the key ...
Early Warning of Abrupt Displacement Change at the Yemaomian Landslide of the Three Gorge Region, China
Publisher: American Society of Civil Engineers
Abstract: Like most natural systems, landslides also have critical points at which a great change in displacement occurs. The displacement may recover increasingly slowly from small perturbations when landslides approach an abrupt ...
Automating Utility Permitting within Highway Right-of-Way via a Generic UML/OCL Model and Natural Language Processing
Publisher: ASCE
Abstract: Each year, thousands of new utilities are installed within the highway right-of-way (ROW) nationwide. This proliferation of utilities yields a great challenge to the traditional practice at road agencies to review, process, ...
Enhanced Risk-Based Quality Control for Hydraulic Engineering Construction Projects Considering the Risk-Influencing Mechanism
Publisher: American Society of Civil Engineers
Abstract: Construction inspection is essential for maintaining the quality of hydraulic engineering projects. Due to the inefficiency and inaccuracy of existing inspection methods, a risk-based approach has been explored to identify ...
