Tree patterns are one of the main abstractions used to access XML data. Tree patterns are used, for instance, to define XML indexes, and support a number of efficient evaluation algorithms. Unfortunately deciding whether a particular query, or query fragment, is a tree pattern is undecidable for most XML Query languages. In this paper, we identify a subset of XQuery for which the problem is dec...
in this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $nondeterministic$ $fuzzy$$finite$ $tree$ $automata$ (nffta). initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). inorder to eliminate these limitations and increasing theefficiency of ffta, we defin...
in this paper we give sharp upper bounds on the zagreb indices and characterize all trees achieving equality in these bounds. also, we give lower bound on first zagreb coindex of trees.
In this study, some silvicultural and growth characteristics of Cercis siliqustrum L. were assessed at Pol-dokhtar and Shineh in northwest and southwest of Khoramabad in Lorestan province. The study areas were delimitated on topographic map by field observations and using GPS. Data were collected from 30 circular plots of 0.1 ha area, by random sampling design. Quantitative and qualitative ch...
Association of Dowling-Degos disease and multiple seborrheick-eratosis in a “Christmas tree pattern”
Dowling-Degos disease is a rare sporadic or autosomal dominant pigmentary entity, in which clusters of papules and reticulate macules slowly develop with predominance in flexural regions. This entity is due to mutations in the keratin 5 gene, and is related with other cutaneous disorders. We report the sporadic form of Dowling-Degos disease in an elderly man with multiple seborrheickeratosis ...
A Framework for Mapping User-designed Forms to Relational Databases Ritu Khare Yuan An, Ph. D. In the quest for database usability, several applications enable users to design custom forms using a graphical interface, and forward engineer the forms into new databases. The path-breaking aspect of such applications is that users are completely shielded from the technicalities of database creation...
