RISModel of Equipment Sharing between Contractors on Construction Projects
Publisher: American Society of Civil Engineers
Abstract: Because of significant characteristics such as complexity and uncertainty, the construction schedules of large-scale projects are often postponed as a result of a shortage of important equipment. By sharing its own incentive ...
Acoustic Wave Splitting and Wave Trapping Designs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic metasurfaces use the phase gradient of a single layer to reflect/refract waves in any direction. This study shows that other than wave steering, acoustic metasurfaces can exhibit wave splitting or trapping through ...
Relationship Network Structure and Organizational Competitiveness: Evidence from BIM Implementation Practices in the Construction Industry
Publisher: American Society of Civil Engineers
Abstract: Using the structural social capital perspective and a longitudinal data set on building information modeling (BIM) implementation practices in the construction industry in Shanghai, China, from 27 to 215, this study explores ...
Dynamics of Collaborative Networks between Contractors and Subcontractors in the Construction Industry: Evidence from National Quality Award Projects in China
Publisher: American Society of Civil Engineers
Abstract: Using the method of stochastic actor-oriented models and a longitudinal data set of the National Quality Award Projects in China during 1998–217, this study empirically investigates how project-based collaborative networks ...
Exponential Stability of Impulsive Switched Nonlinear Systems With Partial Unmeasurable States on Time Scales
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the stability of a class of partially unmeasurable nonlinear impulsive switched dynamical systems on time scales. It provides sufficient conditions for ensuring exponential stability of impulsive ...
Proactive Safety Measures: Quantifying the Upright Standing Stability after Sustained Rebar Tying Postures
Publisher: American Society of Civil Engineers
Abstract: Fall accidents (FAs) constitute a substantial proportion of construction accidents. While the predominant prevention strategy relies on passive approaches (e.g., guardrails), research on proactive measures is lacking, ...
Recognizing Diverse Construction Activities in Site Images via Relevance Networks of Construction-Related Objects Detected by Convolutional Neural Networks
Publisher: American Society of Civil Engineers
Abstract: Timely and overall knowledge of the states and resource allocation of diverse activities on construction sites is critical to resource leveling, progress tracking, and productivity analysis. Despite its importance, this ...
Modeling the Implementation Process for New Construction Technologies: Thematic Analysis Based on Australian and U.S. Practices
Publisher: American Society of Civil Engineers
Abstract: With the boom of innovative technologies, information technologies in construction are getting enough attention, whereas construction technology implementation remains an undiscovered area. This paper explores the process ...
