Forest is a very important ecosystem and natural resource for living things. Based on forest inventories, government is able to make decisions to converse, improve and manage forests in a sustainable ...
Length of prematurity period in wheat cultivars determines maximum cereal aphid abundance
flowering time Metopolophium dirhodum population Rhopalosiphum padi Sitobion avenae spring wheat
2016/9/2
Maximum aphid numbers on wheat are positively related to the length of the period elapsed from immigration to the population peak. We predicted that maximum abundances on late maturing cultivars would...
BEYOND MAXIMUM INDEPENDENT SET: AN EXTENDED MODEL FOR POINT-FEATURE LABEL PLACEMENT
Map labeling point-feature label placement NP-hard
2016/7/8
Map labeling is a classical problem of cartography that has frequently been approached by combinatorial optimization. Given a set of features in the map and for each feature a set of label candidates,...
