A Feature preserved mesh simplification algorithm

  Large-volume mesh model faces challenge in rendering, storing, and transmission due to large size of polygon data. Mesh simplification is one of solutions to reduce the data size.This paper presents a mesh simplification method based on feature extraction withcurvature estimation to triangle mesh. The simplified topology preserves good geometricalfeatures in the area with distinct...

Commodity futures market mechanism: Mathematical formulation and some analytical properties

  This paper deals with the internal structure of a commodity futures market. We proposed a mathematical model representing the mechanism of this market. The model shows the links between market components (transactional prices, transactional quantities, open interest) and traders' states (position, position’s average price, potential wealth and realized wealth). Later, we stated and demonstrated some...
