Supernovae and supernova remnants: Proceedings International Astronomical Union Colloquium, Volume 145

Dramatic advances in ground-based and house astronomy, including serendipitous observations of Supernova 1987a, have made the research of supernovae and supernova remnants the most lively and worthwhile fields in astrophysics. To take inventory of those interesting advancements and to provide concentration to destiny study, the foreign Astronomical Union held a colloquium in Xian, China, for the world's major specialists and this quantity gathers jointly their articles.

Execution time ratio of C-DOVLEI to C-ORDPATH (horizontal axis: depth of node) Fig. 13. Execution time ratio of C-DOVLEI to C-ORDPATH (horizontal axis: XML document) all delimiters one by one. Figure 13 shows the execution time ratio using the document tables. From these results, we deduce that the execution times for extracting depth information and parent labels using the C-DO-VLEI code are about 25% and 15% less than execution times using C-ORDPATH, respectively, which indicates that the proposed method can achieve high performance in such applications as XPath query and keyword search.

Lm we define – – – – – – P to be a legal path, if l1 = ρ and li ∈ E for all i ∈ [1, n−1]1. ¯ denoted by P ⊆ P, ¯ if n ≤ m and li = ¯li for all i ∈ [1, n]. P to be a prefix of P, ¯ ¯ if P ⊆ P¯ and n < m. P to be a strict prefix of P, denoted by P ⊂ P, length(P ) = n to denote the length of P . P, ¯ to be l1 . ¯l1 . ¯lm . the concatenation of P and P, ¯ ¯ to be the intersection of P and P if both are legal paths, denoted by P ∩ P, ¯ the longest path that is a prefix of both P and P . For example, referring to Fig.

Iii) The restrictions on fields means that we only consider inclusion between text/attribute nodes, whereas the keyref mechanism also allows for inclusion between element nodes. We should mention that the restrictions discussed in (i) - (iii) are not intrinsic to our approach, and our definition of an XIND can easily be extended to handle these extension. Our reason for not considering these extensions here is so that we can concentrate on the main contribution of our paper, which is to apply different semantics to an XIND so as to extend relational semantics.
