RISQualitative Analysis of Natural Pozzolanas, Fly Ashes, and Blast Furnace Slags by XRD
Publisher: American Society of Civil Engineers
Abstract: This paper contributes to the knowledge of materials known as active additions, which can be added to Portland cement to give it properties that improve its performance behavior. This knowledge is obtained by X‐ray diffraction ...
Object Tracking With a Range Camera for Augmented Reality Assembly Assistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces a 3D object tracking method for an augmented reality (AR) assembly assistance application. The tracking method relies on point clouds; it uses 3D feature descriptors and point cloud matching with the ...
Evaluation of Economic Impact of Three-Dimensional Modeling in Precast Concrete Engineering
Publisher: American Society of Civil Engineers
Abstract: Sophisticated three-dimensional parametric modeling software for design and detailing of precast/prestressed concrete construction is currently under development. The technology holds the potential to reduce costs, shorten ...
PBL Stratiform Cloud Inhomogeneities Thermally Induced by the Orography: A Parameterization for Climate Models
Publisher: American Meteorological Society
Abstract: This paper proposes a parameterization for use in climate models of the orographic variance and associated thermal circulation's impact on the macroscopic behavior of planetary boundary layer (PBL) stratiform clouds. ...
Agent-Based Simulation of General Contractor–Subcontractor Interactions in a Multiproject Environment
Publisher: ASCE
Abstract: The behavioral dynamics of general contractors and subcontractors in bidding, construction planning, and production control influence the outcomes of construction projects. To date, researchers have modeled these interactions ...
Clustering Information Types for Semantic Enrichment of Building Information Models to Support Automated Code Compliance Checking
Publisher: ASCE
Abstract: Missing, incomplete, implicit, and/or incorrect information are major obstacles to automated code compliance checking in the construction industry. All existing platforms for automated code checking require users to ...
Production Control in Earthworks: Concepts and Metrics
Publisher: ASCE
Abstract: The lean construction theoretical lens afforded by the Transformation-Flow-Value (TFV) theory has led to changes in the way production is understood in building construction projects. However, this new perception of ...
Behavior of Bimetallic Absorber in Parabolic Collectors During DSG to Low Powers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal and mechanical behaviors of absorbers of different material for its application in parabolic collectors during the direct steam generation, with low mass flows (90kg∕hto120kg∕h) and low ...
Impacts of the Social Subcontract and Last Planner System Interventions on the Trade-Crew Workflows of Multistory Residential Construction Projects
Publisher: American Society of Civil Engineers
Abstract: Despite empirical evidence of the effects of the Last Planner System. (LPS), the mechanisms by which it works are less well understood. Its strengthening of the social networks within construction projects implies the ...
