XTFDs: FDs for XML Documents

Functional Dependencies (FDs) are a common constraint for many applications. Specifying FDs in XML documents, however, is difficult because XML documents do not have uniform structures. We introduce XML Template Functional Dependencies (XTFDs), which can specify FDs in XML documents, in this paper. Previously, we defined XTFDs in terms of variables only (Mok, 2005). In this paper, we extend our...

Fds+evac Evacuation Model: Recent Developments

This paper lists the recent developments in the FDS+Evac evacuation model. FDS+Evac is an agent based emergency egress simulation model which is embedded in the fire simulation program FDS, thus, enabling simultaneous simulation of the fire and egress processes. The main new feature of the evacuation module is better treatment of different behavioral types of the evacuees using herding type alg...

Chiral Perturbation Theory for fDS/fD and BBS/BB

The decay constants for the D and DS mesons, denoted fD and fDS respectively, are equal in the SU(3)V limit, as are the hadronic amplitudes for BS−BS and B0−B 0 mixing. The leading SU(3)V violating contribution to (fDS/fD) and to the ratio of hadronic matrix elements relevant for BS − BS and B − B 0 mixing amplitudes are calculated in chiral perturbation theory. We discuss the formalism needed ...
