A Light Transmission Model For Biological Materials, R. A. Cavaletto, Shrinivasa Upadhyaya, Michael O'Brien
A Light Transmission Model For Biological Materials, R. A. Cavaletto, Shrinivasa Upadhyaya, Michael O'Brien
Richard Cavaletto
This paper describes a model to predict light transmission in biological materials. The model can be used for any shaped sample. Scattering and absorption coefficients are used in the model and may be varied throughout the sample, thus allowing both uniformly distributed and concentrated defects to be modelled.
Evaluation Of Two Models For Light Transmission In Biological Materials, R. A. Cavaletto, S. Upadhyaya, M. O'Brien, T. Cahill
Evaluation Of Two Models For Light Transmission In Biological Materials, R. A. Cavaletto, S. Upadhyaya, M. O'Brien, T. Cahill
Richard Cavaletto
Two light transmission models for biological materials are developed and evaluated. The energy balance model showed promise. It's developed as a 3 coefficient model permitting varied sample absorption and scattering properties. The second model performed unsatisfactorily.
Spray Drift Reduction With Shrouded Boom Sprayers, Ronald J. Fehringer, Richard Cavaletto
Spray Drift Reduction With Shrouded Boom Sprayers, Ronald J. Fehringer, Richard Cavaletto
Richard Cavaletto
Downwind drift was measured from a standard boom sprayer and a shrouded boom sprayer. Using 8002 flat fan nozzles, the hooded sprayer provided a 180 to 275% reduction in drift. The effectiveness of the shroud is dependent upon the spray droplet spectrum.
Evaluating Strength & Energy Requirements For Workers Picking Vegetables, R. A. Cavaletto, J. Miles, J. Meyers, J. Mehlschau
Evaluating Strength & Energy Requirements For Workers Picking Vegetables, R. A. Cavaletto, J. Miles, J. Meyers, J. Mehlschau
Richard Cavaletto
The paper discusses the need to obtain field data to evaluate the strength and energy requirements for workers picking a variety of vegetables. This information is central to the evaluation of hazards related to repetitive motion, excessive stress, and fatigue. Results can be used to select activities which should be targeted for future engineering design projects. Preliminary data from a commercial broccoli harvesting operation is included.
Guarding Of Table Saws With Light Beams: The Light Guard Concept, R. A. Cavaletto, M. S. Kaminaka, C. M. Zahner
Guarding Of Table Saws With Light Beams: The Light Guard Concept, R. A. Cavaletto, M. S. Kaminaka, C. M. Zahner
Richard Cavaletto
This paper describes a unique type of psychological safety guard for hazardous tools such as table saws, presses. and other tools with areas and components which are dangerous to human fingers, hands, and limbs. It is not a piece of hardware but rather a shalt of light which defines a danger zone around the saw blade or cutting area.
