Estimating Passive Stress Acting On A Grain Entrapment Victim’S Chest, Salah F. Issa, Carl Wassgren, Charles V. Schwab, Richard Stroshine, William E. Field

Agricultural and Biosystems Engineering Publications

Grain entrapments remain a major concern in the grain industry, with 1,100 incidents documented since the 1970s. One particular concern is the ability of a victim to breathe while entrapped in grain. Anecdotal reports suggest that victims struggle to breathe when entrapped in grain to a depth that covers their chests, yet some evidence indicates that victims should be able to breathe normally as long as their airways are not blocked regardless of depth. The hypothesis for this discrepancy is that previously published experiments measured an active stress state in the grain, while a person breathing also experiences a ...


Prediction Of Extraction Forces For Entrapment Victim In Common Grain Storage Conditions, Charles V. Schwab, Pamela J. Schwab, Lauren E. Schwab Jan 2018

Prediction Of Extraction Forces For Entrapment Victim In Common Grain Storage Conditions, Charles V. Schwab, Pamela J. Schwab, Lauren E. Schwab

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

One contributor to agriculture’s high death rate is confined space fatalities caused by entrapment in granular materials. Over 1,000 grain-related fatalities have been documented by researchers in 43 states, and those states with the largest grain storage capacities have been shown to experience a proportionally large number of the suffocation fatalities. Several researchers have measured extraction forces in specific conditions, but a reference standard for estimating the extraction forces for a grain suffocation victim in common conditions is needed. A prediction model for estimating extraction forces was developed using the principle of boundary shear, an approximation of human ...

Systematic Design For Trait Introgression Projects, John N. Cameron, Ye Han, Lizhi Wang, William D. Beavis

Industrial and Manufacturing Systems Engineering Publications

We demonstrate an innovative approach for designing Trait Introgression (TI) projects based on optimization principles from Operations Research. If the designs of TI projects are based on clear and measurable objectives, they can be translated into mathematical models with decision variables and constraints that can be translated into Pareto optimality plots associated with any arbitrary selection strategy. The Pareto plots can be used to make rational decisions concerning the trade-offs between maximizing the probability of success while minimizing costs and time. The systematic rigor associated with a cost, time and probability of success (CTP) framework is well suited to designing ...
