One of the most commonly used means to characterize potential energy surfaces of reactions and chemical systems is the Hessian calculation, whose analytic evaluation is computationally and memory demanding. A new scalable distributed data analytic Hessian algorithm is presented. Features of the distributed data parallel coupled perturbed Hartree-Fock (CPHF) are (a) columns of density-like and F...

The Network management, analysis, and testing environment (Netmate) project addresses research and experimental issues in distributed network management of large, heterogeneous networks. This paper describes the Netmate architecture, and its model for network management information, which emphasizes the definition of generic network objects and relationships chosen specifically for efficient ne...

extended abstract 1. introduction city is a living creature formed through the interaction of different forces in unique substantiality. one of the main aspects of each city is its landscape; urban landscape is the experience of people as the members of society. landscape is an objective and subjective phenomenon that is the part of peoples’ nature in a city. in fact, the process of landscape p...

Previous analytic approaches for all-optical networks have only allowed a random wavelength assignment policy in spite of the fact that network performance can be improved by other wavelength assignment policies such as first-fit wavelength assignment. In this paper, we develop an approximate analytic method to allow flexible wavelength assignment policies by virtue of a layeredgraph approach. ...
