• Motion Editing and Reuse Techniques and Their Role in Studying Events Between a Machine and its Operator
  4/1/2002 - Conference papers
  The first part of this paper is a review of several new techniques developed to facilitate the manipulation, noise reduction, storage and reuse of captured data, which have a potential to reduce the overall cost of motion simulation and improve its real...
• Verification and Validation of Roof Bolter Simulation Models for Studying Events Between a Machine and its Operator
  6/1/2001 - Conference papers
  This paper presents the results of a study to verify and validate a computer model that represents and analyzes motions and hazardous events in a simulated three-dimensional workplace. The purpose of the computer model is to support research that is in...
• Computer Modeling of Catch Benches to Mitigate Rockfall Hazards in Open Pit Mines
  7/1/2000 - Conference papers
  In a computer analysis of bench stability, bench-scale plane shears and tetrahedral wedges are simulated and stochastically analyzed to estimate the probability of retaining specified catch-bench widths.
• A Simulation Approach Analyzing Random Motion Events Between a Machine and its Operator
  1/1/2000 - Conference papers
  An approach for representing and analyzing random motions and hazardous events in a simulated three-dimensional workplace, providing designers and analysts with a new technique for evaluating operator-machine interaction hazards in virtual environments.
• Use of Strain-Gauged Rock Bolts to Measure Rock Mass Strain During Drift Development
  6/1/1999 - Conference papers
  An experiment is described in which instrumented rock bolts were used to measure strain in the rock mass during drift development at the Stillwater Mine, Nye, Montana, USA.
• Design Analysis of Underground Mine Ore Passes: Current Research Approaches
  5/1/1998 - Conference papers
  The U.S. Mine Safety and Health Administration (MSHA) has identified ore pass hazards as s significant safety problem in underground metal mines in the United States. Researchers at the Spokane Research Laboratory of the National Institute for Occupati...
