The next generation of electronic components will require new low-k dielectrics or other novel thin films in the sub-micron level to be integrated into their...
This paper describes our experiences in developing a highly configurable, extensible, component-based tool for the creation of conformance tests for XML...
Evaluating competing technologies on a common problem set is a powerful way to improve the state of the art and hasten technology transfer. Yet poorly designed...
Traditional approaches to network provisioning assume availability of the reliable estimates for the expected demands. This assumption, however, oversimplifies...
Finding shortest feasible paths in a weighted graph has numerous applications including admission and routing in communication networks. This paper discusses a...
High-capacity optical-fiber backbone networks protect information flows belonging to their premium customers by routing two copies of the customer's data over...

A multi-phase field model was used to study the three-dimensional dynamics of morphology evolution in binary eutectics. Performing the calculations in three...
For several decades maleated polypropylene (mPP) has been blended with polypropylene (PP) in an effort to improve the adhesion of PP to composite reinforcements...
Droplet breakup in homogeneous shear flow at super critical Capillary numbers and a viscosity ratio of unity is studied using a lattice Boltzmann method. We...
In the extrusion of polyethylene (PE), fluoropolymer-processing additives (PPA) are used to eliminate the surface defect known as sharkskin by coating the die...
The dispersal of high boiling point liquid fire suppression agents around solid obstacles is investigated to obtain a better understanding of the physical...
