Assessing manual lifting tasks based on segment angle interpolations.
This study investigates the effects of the number of interpolation points on the prediction accuracy of segment angle trajectory during lifting. Ten participants performed various lifting tasks while a motion tracking system recorded their movements. Two-point through ten-point equal time-spaced segment angles extracted from major segment trajectory data captured by the motion tracking system w...
متن کاملThe Effect of Lifting Speed on Cumulative and Peak Biomechanical Loading for Symmetric Lifting Tasks
BACKGROUND To determine the influence of lifting speed and type on peak and cumulative back compressive force (BCF) and shoulder moment (SM) loads during symmetric lifting. Another aim of the study was to compare static and dynamic lifting models. METHODS Ten male participants performed a floor-to-shoulder, floor-to-waist, and waist-to-shoulder lift at three different speeds [slow (0.34 m/s),...
متن کاملEvaluation of a Harmony Search Algorithm for Manual Lifting Tasks Optimization
This paper presents near optimal solution method to find safe work place design using harmony search algorithm. Revised NIOSH equations are considered to minimize relative estimate of the physical stress associated with a manual-lifting job. The proposed algorithm will assist occupational safety and health practioners in evaluating lifting tasks and reducing the incidence of low back injuries i...
متن کاملA field evaluation method for assessing whole body biomechanical joint stress in manual lifting tasks.
Work-related musculoskeletal injuries are often associated with overexertion of the body at work. The manual materials handling activity of lifting is a major source of work-related musculoskeletal disorders. Biomechanical evaluation offers useful information about the physical stress imposed on the worker's body joints; however, biomechanical analysis is usually tedious and complex. For evalua...
متن کاملOptimal Type Lifting Optimal Type Lifting
Modern compilers for ML-like polymorphic languages have used explicit run-time type passing to support advanced optimizations such as intensional type analysis, representation analysis and tagless garbage collection. Unfortunately, maintaining type information at run time can incur a large overhead to the time and space usage of a program. In this paper, we present an optimal type-lifting algor...
