Updating the prepost plane in monetdbxquery

However, once updates are involved, variable-length surrogates are often considered the better choice, mainly as a straightforward implementation of structural XML updates using fixed-length surrogates faces two performance bottlenecks: (i) high physical cost (the preorder ranks of all nodes following the update position must be modified—on average 50% of the document), and (ii) low transaction concurrency (updating the size of all ancestor nodes causes lock contention on the document root).

AB - Relational XQuery processors aim at leveraging mature relational DBMS query processing technology to provide scalability and efficiency.

From 1999 - 2002 he was a consultant to Sandia National Laboratories providing documentation, verification and validation for the constitutive models used by the Engineering & Manufacturing Mechanics Group.

He has a strong interest in verification and validation in computational solid mechanics, and is the recent past Chair of the ASME Standards Committee on Verification and Validation in Computational Solid Mechanics.

Additional time is allocated at the end of each day for one-on-one participant discussion with the instructor.

Really a great course and one I would highly recommend to others.

Recent research [1] showed a clear advantage of the former for efficient evaluation of XPath location steps, exploiting techniques like cheap node order tests, positional lookup, and node skipping in staircase join [7].

Len Schwer has worked on concrete & geomaterial applications, and developed constitutive models, for the past 25 years; he has been a DYNA3D user since 1983 and an LS-DYNA user since 1998.

His early work at SRI International included the development of a Mohr-Coulomb constitutive model for modeling the rock surrounding tunnels under very high pressure loadings.
