A Data Parallel Algorithm for XML DOM Parsing
A Data Parallel Algorithm for XML DOM Parsing

... Abstract. The extensible markup language XML has become the de facto standard for information representation and interchange on the Internet. XML parsing is a core operation performed on an XML document for it to be accessed and manipulated. This operation is known to cause performance bottlenecks i ...

... structure which searches an element in equal amount of time as binary search requires O(log2 N)[1][5]. But it is difficult to maintain and manipulate binary search tree. The second option to implement binary search on linked list is to copy all the elements of linked list into either sorted array or ...

... Index pages can typically hold many more entries than leaf pages. Variable sized records and search keys mean different nodes will contain different numbers of entries. Even with fixed length fields, multiple records with the same search key value (duplicates) can lead to variable-sized data entr ...

The problem with these indices is that they require space several times the text size in addition to the text itself. Thus ...

... the tree on the right. Since vertex reductions do not change the essential structure of the contour tree, we prefer them to leaf prunes. Also, pruning the only up- or down- edge at a saddle is prohibited to preserve the edge for a later vertex reduction. It is clear that these operations can simplif ...

Quadtree



A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
