Motion and Visual Data-Driven Distant Object Localization for Field Reporting
(American Society of Civil Engineers, 2018)The field reporting methods in the architecture/engineering/construction and facility management (AEC/FM) industry are in the middle of a major change in terms of how tasks are being conducted in the field. One of the key ... -
Identification and Characterization of Particle Shapes from Images of Sand Assemblies Using Pattern Recognition
(American Society of Civil Engineers, 2018)Pattern recognition was used on images of contacting three-dimensional sand particle assemblies to detect foreground sand grains that exhibit full-particle projections. Once identified, the roundness and sphericity of those ... -
Application of an Inexpensive Sensor in Calculating the International Roughness Index
(American Society of Civil Engineers, 2018)The international roughness index (IRI) is one of the most common indices applied in the assessment of road roughness. The initial step in calculating the IRI is to collect depth data from a road surface. Depth data is ... -
Hybrid Reliability Analysis Framework for Reliability Analysis of Tunnels
(American Society of Civil Engineers, 2018)Numerical modelling of tunnels, generally carried out by using some numerical analysis tools [e.g., finite element (FE) method, discrete element method], is often computationally expensive. Hence, it becomes extremely ... -
Optimum Seismic Design of 3D Irregular Steel Frames Using Recently Developed Metaheuristic Algorithms
