Prediction of slip resistance in climbing systems
(Elsevier, 1991-07)
The objective of this study was to develop a predictive model describing the slip resistance of various climbing surfaces. In a four-factor experiment, seven commonly used metal grating step surfaces were evaluated, along ...
Simplex Algorithm for Countable-state Discounted Markov Decision Processes
(2014-11-18)
We consider discounted Markov Decision Processes (MDPs) with countably-infinite state spaces, finite action spaces, and unbounded rewards. Typical examples of such MDPs are inventory management and queueing control problems ...
A checklist for evaluating ergonomic risk factors resulting from awkward postures of the legs, trunk and neck
(Elsevier, 1992-06)
A one-page checklist for determining the presence of ergonomic risk factors associateed with awkward postures of the lower extremities, trunk and neck was developed and evaluated as part of a joint labor-management ergonomics ...
A Hit-and-Run approach for generating scale invariant Small World networks
(Wiley Subscription Services, Inc., A Wiley Company, 2009-01)
Hit-and-Run is a well-known class of Markov chain algorithms for sampling from essentially arbitrary distributions over bounded regions of the Euclidean space. We present a class of Small World network models constructed ...
A Reach and Bound algorithm for acyclic dynamic-programming networks
(Wiley Subscription Services, Inc., A Wiley Company, 2008-08)
Node pruning is a commonly used technique for solution acceleration in a dynamic-programming network. In pruning, nodes are adaptively removed from the dynamic programming network when they are determined not to lie on an ...
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 ...
Rank-Cluster-and-Prune: An algorithm for generating clusters in complex set partitioning problems
(Wiley Subscription Services, Inc., A Wiley Company, 2009-04)
Clustering problems are often difficult to solve due to nonlinear cost functions and complicating constraints. Set partitioning formulations can help overcome these challenges, but at the cost of a very large number of ...
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 ...
Control of manufacturing networks which contain a batch processing machine
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-11)
We consider the control of a batch processing machine which is part of a larger manufacturing network of machines. Systems consisting of a batch processing machine and one or more unit-capacity machines in tandem are ...
