Chipper - A Novel Algorithm for Concept Description
In this paper, several demands placed on concept description algorithms are identified and discussed. The most important criterion is the ability to produce compact rule sets that, in a natural and accurate way, describe the most important relationships in the underlying domain. An algorithm based on the identified criteria is presented and evaluated. The algorithm, named Chipper, produces deci...
متن کاملMachine Vision Systems for Processing Hardwood Lumber and Logs
Machine vision and automated processing systems are under development at Virginia Tech University with support and cooperation from the USDA Forest Service. Our goals are to help U.S. hardwood producers automate, reduce costs, increase product volume and value recovery, and market higher value, more accurately graded and described products. Any vision system is composed of two bread tasks: imag...
متن کاملElectroweak Double-logs at Small X
We investigate enhanced EW corrections to inclusive hard processes in the TeV energy region with emphasis on the small-x situation, in which the hard scale Q is significantly smaller than the available energy √ s ≡ Q/x. We first propose and justify a general factorization formula in which the (double-log) EW form factor at scale Q is factorized from EW parton distribution functions, which satis...
متن کاملComminution of Logging Residues with Evolution 910R chipper, MOHA chipper truck, and Morbark 1200 tub grinder
This study is part of the ongoing national Bioenergy Research Programme in Finland. The study looked into the quality of chips made of logging residues composed predominantly of spruce wood. In addition, the productivity of the Evolution 910R chipper, the MOHA chipper truck, and the Morbark 1200 tub grinder was studied. The three machines studied were capable of producing acceptable chips for h...
متن کاملEVALUATION OF CHIPPER - FORWARDER BIC & fASS HARVESTING
-A chipper-fonuarder system offers an alternative for biomass hawcstfng. Components are a small feller buncher for felling and bunching. and a chipper-forwarder that chips at the pile and transports the chips to roadside. In a case study on a mixed pine and hardwood site in Georgia after conventional hawesting, production rates and cost estimates for a prototype chfpperforwarder were developed....
