A nominal finite element solver is proposed for data-driven strain elasticity. It bypasses the need a constitutive model by considering database of deformation gradient/first Piola–Kirchhoff stress tensors pairs. The boundary value problem reformulated as constrained minimization distance between (i) mechanical states, i.e. strain–stress, in body and (ii) material states coming from database. c...

Knowledge embedded in a data stream is likely to be changed as time goes by. Identifying the recent change of the knowledge quickly can provide valuable information for the analysis of the data stream. However, most mining algorithms over a data stream are not able to extract the recent change of knowledge in a data stream adaptively. This is because the obsolete information of old data element...

This paper presents a graph parsing approach to recognizing common stereotypical computational structures called clich es in com puter programs Recognition is a powerful technique for e ciently recon structing useful design information from existing software We use a ow graph formalism which is closely related to hypergraph formalisms to represent programs and clich es and we use attributed ow ...

The coding and compression of weather imagery can be improved by following a domain-specific approach in which the characteristics of the data are taken into account in devising the encoding scheme. We show that by predicting that the next valid data element is identical to the current one, a dramatic reduction in source entropy (information content) is achieved. We also show that encoding runs...
