Limited research has been directed toward bulk crop (i.e., potato, sugarbeet, etc.) yield monitoring over the last several years (Hofman et ai., 1995; Rawlins et ai., 1995; Campbell et al. , 1994; and Walter et al., 1996). Results have shown that the

A field study was conducted to evaluate three real-time weighing systems to measure sugarbeet yield. Two systems permit use of the storage hopper onboard the harvester. The effects of tare on yield measurement were investigated. Parallel yield data f

A site-specific sugarbeet yield monitoring system was developed and tested. Two weight-sensing systems were developed, tested, and evaluated on a laboratory test conveyor. One system used 152 mm (6 in.) idler wheels attached to load cells. The instru

A novel segmentation approach that partitions color images into two uniform regions is described. This unsupervised procedure is based on a self–organizing map neural network and fuzzy c–means clustering (SOM_FCM). The self–organizing map allow

A filtration system was developed to test for particulate matter in 1.6 liter samples of fuel. Four micron, absolute, filter paper was used. Four alkali refined sunflower oils, two of which were also dewaxed, were tested along with 50:50% and 25:75%

A ventilation system was designed, implemented, and evaluated for the reduction of sugar losses in stored sugar beets. Design parameters for ventilation and freezing were determined and an above ground duct system was built and installed. Sugar beets
