ABSTRACT In previous work, a periodic surface model for computeraided nano-design (CAND) was developed. This implicit surface model can construct Euclidean and hyperbolic nano geometries parametrically and represent morphologies of particle aggregates and polymers. In this paper, we study the characteristics of degree elevation and reduction based on a generalized periodic surface model. Method...

Abstract. Lossy compression has been applied to the data of large-scale Earth system model (ESMD) due its advantages a high ratio. However, few lossy methods consider both global and local multidimensional coupling correlations, which could lead information loss in approximation compression. Here, an adaptive method, hierarchical geospatial field representation (Adaptive-HGFDR), is developed ba...
