ABSTRACT To reduce the damage caused by logging in Amazon rainforest, new metaheuristics have been implemented and tested to ensure sustainability of this economic segment. Therefore, study aimed compare alternatives for road sizing log deck allocation. In a forest management unit, skidding decks was evaluated two different areas. determine skidding/log relation, georeferenced points were gener...

Recently, Pawlik et al. have shown that triangle-free intersection graphs of line segments in the plane can have arbitrarily large chromatic number. Specifically, they construct triangle-free segment intersection graphs with chromatic number Θ(log log n). Essentially the same construction produces Θ(log log n)-chromatic triangle-free intersection graphs of a variety of other geometric shapes—th...

This paper examines the effect of the default interface language on the usage of a bilingual digital library. In 2005 the default interface language of a bilingual digital library was alternated on a monthly basis between Māori and English. A comprehensive transaction log analysis over this period reveals that not only did usage in a particular language increase when the default interface langu...
