Three methods for measuring range of motion while wearing protective clothing: A comparative study
(Elsevier, 1993-10)
This paper evaluates three methods for objectively measuring ROM while workers are wearing protective clothing: a universal goniometer, a Leighton Flexometer, and an electrogoniometer. Ten male subjects performed a set of ...
Hand-arm frequency-weighted vibration effects on tactility
(Elsevier, 1990-07)
This study reports results of an investigation into the short-term effects of power hand tool vibration on deep sense tactile sensitivity. Five subjects operated a simulated hand tool using a 30 s / 30 s work / rest duty ...
The strengths and limitations of lecture-based training in the acquisition of ergonomics knowledge and skill
(Elsevier, 1990-03)
A common approach to training designers of workplaces to incorporate ergonomic considerations in their designs is a two- to five-day course based primarily on lectures by experts. A quiz, designed to test the acquisition ...
Validation of a biodynamic model of pushing and pulling
(Elsevier, 1991)
Pushing and pulling during manual material handling can increase the compressive forces on the lumbar disc region while creating high shear forces at the shoe-floor interface. A sagittal plane dynamic model derived from ...
Simulated annealing for constrained global optimization
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-09)
Hide-and-Seek is a powerful yet simple and easily implemented continuous simulated annealing algorithm for finding the maximum of a continuous function over an arbitrary closed, bounded and full-dimensional body. The ...
Base-stock control for single-product tandem make-to-stock systems
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
In this paper, we consider a multiple-stage tandem production/inventory system producing a single product. Processing time at each stage is assumed to have a general stationary processing time distribution. The cost of ...
Evaluating posture behavior during seated tasks
(Elsevier, 1991-12)
A method was developed to evaluate posture behavior of the trunk, neck, eye, and upper extremity in three-dimensional space during the performance of static, seated tasks. Body postures were measured using an ultrasonic ...
Pure adaptive search in global optimization
(Springer-Verlag; The Mathematical Programming Society, Inc., 1992-01)
Pure adaptive seach iteratively constructs a sequence of interior points uniformly distributed within the corresponding sequence of nested improving regions of the feasible space. That is, at any iteration, the next point ...
Note on combinatorial optimization with max-linear objective functions
(Elsevier, 1993-04-27)
We consider combinatorial optimization problems with a feasible solution set S[subset of or equal to]{0,1}n specified by a system of linear constraints in 0-1 variables. Additionally, several cost functions c1,...,cp are ...
Denumerable state nonhomogeneous Markov decision processes
(Elsevier, 1990-11-15)
We consider denumerable state nonhomogeneous Markov decision processes and extend results from both denumerable state homogeneous and finite state non-homogeneous problems. We show that, under weak ergodicity, accumulation ...
