Construction Activity Recognition and Ergonomic Risk Assessment Using a Wearable Insole Pressure System
Publisher: ASCE
Abstract: Overexertion-related construction activities are identified as a leading cause of work-related musculoskeletal disorders (WMSDs) among construction workers. However, few studies have focused on the automated recognition ...
Sweat Analysis-Based Fatigue Monitoring during Construction Rebar Bending Tasks
Publisher: ASCE
Abstract: This study proposes a novel approach to monitor the fatigue levels of construction rebar benders by measuring chemical biomarkers using sweat sensors. Fatigue resulting from dehydration and energy depletion can severely ...
Online Assessment of Spontaneous Mental Fatigue in Construction Workers Considering Data Quality: Improved Online Sequential Extreme Learning Machine
Publisher: American Society of Civil Engineers
Abstract: Biological data-based methods for monitoring workers’ mental fatigue have become widely adopted in recent years. However, few have concentrated on the online monitoring and assessment of mental fatigue considering the ...
Ontology-Based Semantic Modeling of Knowledge in Construction: Classification and Identification of Hazards Implied in Images
Publisher: ASCE
Abstract: Identifying potential hazards of construction project is a data-intensive process that involves various types of information such as site data, specifications, and engineering documents. How to effectively convert the ...
