Scaled Boundary FEM Model for Interaction of Short-Crested Waves with a Concentric Porous Cylindrical Structure
Publisher: American Society of Civil Engineers
Abstract: This paper describes the development of an efficient scaled boundary finite-element model (FEM) for the simulation of short-crested wave interaction with a concentric porous cylindrical structure. By weakening the governing ...
Automatic Detection of Tangential Discontinuities in Point Cloud Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A point cloud data set, a dense set of discrete coordinate points scanned or sampled from the surface of a 3D physical object or design model, is emerging as a new representation format for ...
Robust Initial Matching of Free-Form Objects Represented by Point Clouds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of best matching two point cloud data sets or, mathematically, identifying the best rigid-body transformation matrix between them, arises in many application areas such as geometric ...
Effects of High Temperature on Creep Properties of Cement and Emulsified Asphalt Mortar
Publisher: ASCE
Abstract: As an inorganic–organic composite material, cement and emulsified asphalt (CA) mortar has been used widely in ballastless slab track structures, and its performance is influenced significantly by environmental conditions. ...
Direct Inversion Algorithm for Pipe Resistance Coefficient Calibration of Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: To enable a water distribution system (WDS) model to yield predictions with a reasonably good match to measurements, pipe resistance coefficients (PRCs) of the model often need to be calibrated. The majority of methods ...
