RISConditional Nonlinear Optimal Perturbations: Adjoint-Free Calculation Method and Preliminary Test
Publisher: American Meteorological Society
Abstract: An ensemble-based approach is proposed to obtain conditional nonlinear optimal perturbation (CNOP), which is a natural extension of linear singular vector to a nonlinear regime. The new approach avoids the use of adjoint ...
Biomechanical Cell Model by Liquid-Crystal Elastomers
Publisher: American Society of Civil Engineers
Abstract: In this work, a soft matter cell model is proposed to simulate the cellular cytoskeleton network and motions of intermediate filaments during cell contact and adhesion, in an attempt to explain mechanical information ...
Exploring the Quantitative Impact of Localization Accuracy on Localization-Based Safety Monitoring’s Performance on a Construction Jobsite
Publisher: American Society of Civil Engineers
Abstract: The construction industry continues to be one of the industries with the highest accident rate. With the recent advancement of computing and sensing technologies, more efforts have been made in the field of context-aware ...
TableGraph: An Image Segmentation–Based Table Knowledge Interpretation Model for Civil and Construction Inspection Documentation
Publisher: ASCE
Abstract: There are many manuals and codes to normalize each procedure in civil and construction engineering projects. Data tables in the codes offer various references and are playing a more and more valuable role in knowledge ...
Cloud-IDA-MSA Conversion of Fragility Curves for Efficient and High-Fidelity Resilience Assessment
Publisher: ASCE
Abstract: In performance-based earthquake engineering framework, seismic fragility functions play a fundamental role for quantifying the seismic resilience. There are three main approaches for performing the seismic fragility analysis: ...
Embodied Cost of Collusive Bidding: Evidence from China’s Construction Industry
Publisher: ASCE
Abstract: Collusive bidding is regarded as one of the most socially harmful, anticompetitive, and illegal practices in the construction sector. The process of collusion is hidden from public sight, making it difficult to calculate ...
The Spatial Distribution of Microbially Induced Carbonate Precipitation in Sand Column with Different Grouting Strategies
Publisher: ASCE
Abstract: For ground improvement via microbially induced carbonate precipitation (MICP), the spatial distribution of biocementation considerably affects the mechanical performance of soil. This study systematically assessed the CaCO3 ...
Ductile Behavior of Scoured RC Pile-Group Foundations for Bridges in Cohesionless Soils: Parametric Incremental Dynamic Analysis
Publisher: ASCE
Abstract: Scoured pile-group foundations (SPGFs) are susceptible to inelastic deformation during earthquakes. Hence, the ductile behavior of SPGFs has become a rising concern in academic and industrial communities. Traditionally, ...
Impact of Age on Construction Workers’ Preattentive and Attentive Visual Processing for Hazard Detection
Publisher: ASCE
Abstract: The growing number of older workers affects occupational safety in the context of the construction industry’s aging workforce. The first step in proactively reducing safety accidents is hazard detection, which involves ...
Effects of Physical Fatigue on Construction Workers’ Visual Search Patterns during Hazard Identification
Publisher: American Society of Civil Engineers
Abstract: Physical fatigue is a frequent factor in construction workplaces that threatens workers’ safety. This study examines whether fatigue alters visual search patterns adopted by workers during hazard identification, thereby ...
