This paper discusses methods enhancing the selection of a “best” parsing tree from the output of natural language syntactic analysis. It presents a method for cutting away redundant parse trees based on the information obtained from a dependency tree-bank corpus. The effectivity of the enhanced parser is demonstrated by results of intersystem parser comparison. The test were run on the standard...

Rooted stem cuttings of forest trees are increasingly being used around the world to deploy elite genotypes in intensive forest plantations. In 1992, the NCSU Loblolly and Slash Pine Rooted Cutting Program was formed as an industrially sponsored research cooperative. The primary mission of the program is to conduct research to facilitate the operational use of rooted cuttings for the pines of t...

The encroachment of Eastern redcedar (ERC) (Juniperus virginiana L.) onto Great Plains prairies has become a serious threat to ecosystem functioning and grazing productivity. uncontrolled spread this invasive tree species been called »green glacier« converting grasslands into closed canopy woodlands. A pasture cutting robot was developed using tracked Autonomous Ground Vehicle (AGV) equipped wi...

Remnant trees, spared from cutting when tropical forests are cleared for agriculture or grazing, act as nuclei of forest regeneration following field abandonment. Previous studies on remnant trees were primarily conducted in active pasture or old fields abandoned in the previous 2-3 years, and focused on structure and species richness of regenerating forest, but not species composition. Our stu...

Plants cut at different times produce resprouts that vary in their nutritional value relative to when they are cut. To determine how vegetation management in transportation (road and rail) corridors at different times of the year could influence browse quality in the years following cutting, and how this could potentially influence encounters between herbivores and vehicles, we undertook a 3-ye...

Most tropical forests are government-owned, with timber being harvested under concession agreements awarded to private logging companies. Those agreements tend to be short-term harvesting licenses lasting no more than one to a few years. In the absence of regulation, loggers can be expected to ignore the negative environmental impacts of logging, as they derive little or no financial gain from ...
